"Water is the source of life, and we must protect every drop of water." This sentence is true. If there is no water, the earth will dry up; if there is no water, we humans may die of thirst. ; If there was no water, there would be no beautiful world of ours. We must cherish every drop of water and every tear of Mother Earth.
There are many students in our school who, after class, run to the faucet, turn on the faucet, and then pour water on others. He didn't turn off the faucet when he left, he just ran as fast as he could.
I once did such a "stupid" thing.
Every week, my sister and I play with water. We turn on the faucet, and the red triangle in the water meter starts spinning. The bigger you turn the faucet, the faster the red triangle spins, and the more you pay for water.
One day, my sister and I were playing with water again. As soon as my sister turned on the faucet, the red triangle in the water meter started spinning again. My sister looked at it and said to herself: "It would be great if the water flowed out and the water meter didn't run!" I happened to hear this sentence by the side. I thought about it and said: "Sister, we As long as you turn the faucet down, the water meter will stop running." "Really?" my sister asked in surprise. "If you don't believe me, try it yourself." My sister tried it, and sure enough, it was just as I said. My sister asked happily and surprised: "Who told you?" "No one told me." "Yesterday, after I washed my face, I didn't close the faucet tightly. The water flowed out drop by drop, but the water meter didn't move at all. "I said to her mysteriously. "Okay, okay, okay! Then let's accumulate water quickly." But when she thought about it, she frowned, and her sister said, "This is too slow!" "It doesn't matter, we only need to accumulate water from morning to noon, right? A lot of water?" She immediately stepped forward and said, "A little adds up to a lot." After saying that, we both let out a low knowing laugh.
This "secret" was finally discovered by my father.
We rushed to tell our dad this "secret", thinking that dad would praise us. Who knew, my father said to us earnestly: "Do you know what you are doing? This is stealing water!" "Ah? My sister and I were stunned. We have all become thieves, it's so serious! Dad said again: " If everyone is like you, who will pay the water bill for the country! Didn’t you steal the country’s water? After all, it’s inappropriate to waste water! "After hearing these thought-provoking words from my father, my sister and I's faces suddenly turned red. After a while, I suddenly raised my head, pointed at the basin of water and said, "Dad, let's hand over this basin of water. Bar! "That's not necessary. You can't do this again in the future." "Dad said to us seriously. We answered resoundingly: "Yes! ”
Students, if you are like this, please correct it quickly!
Water is the source of life, we must save every drop of water...

Water is one of the important resources for human survival and development. It is an indispensable and irreplaceable special resource. Without water, there will be no life and no progress in civilization. Water is limited and cannot be used without limit. In today's world, with the continuous growth of population and the continuous development of economy, the demand for fresh water resources is increasing; at the same time, due to unreasonable utilization, the already scarce fresh water resources are becoming increasingly tense. .
Historically, my country is a country with frequent droughts. It is known as "nine droughts in ten years". In more than 2,200 years of historical records, major droughts have occurred 1,300 times. my country's per capita water resources are only about 2,300 cubic meters, which is about one-quarter of the world's per capita water resources. my country's water resources are not only small per capita, but also extremely unevenly distributed. The watershed area north of the Yangtze River accounts for 10% of the country's total land area. However, water resources account for 19% of the country's total area. With the development of my country's society and economy, the water gap is getting bigger and bigger. At present, the average annual water shortage for agricultural irrigation in our country is more than 30 billion cubic meters, and there are still more than 30 billion cubic meters of water in rural areas across the country. More than 30 million people have difficulty drinking water. More than 400 cities across the country are short of water, and there are more than 110 cities with serious water shortages. The daily water shortage in cities across the country is 16 million cubic meters. Every year, the industrial output value is affected by more than 200 billion yuan due to water shortage. , affecting an urban population of about 40 million people.
It can be said that through years of efforts, my country's water conservation industry has made great progress, but compared with some developed countries, we still lag behind. .
Agriculture is a large user of water resources and a large waste of water resources. In our country, the agricultural irrigation method of "earth canal water delivery and flood irrigation" is still widely used. Half of the irrigation water is lost through leakage during water delivery. The utilization coefficient of irrigation water is mostly only 0.4, which is lower than that of some developed countries. half level. In my country, the grain yield increased by 0.5 kilograms per square meter of water irrigation, while in developed countries it can reach 2 kilograms. In industry, due to the backward technology of existing water facilities, my country's current industrial water consumption per 10,000 yuan of output value is 103 cubic meters, compared with 8 cubic meters in the United States and only 6 cubic meters in Japan, which is 10 to 20 times that of developed countries; reuse of industrial water in my country The rate is only about 40%, while the average in developed countries is 75% to 85%. The phenomenon of urban residents not saving water for domestic use is very serious. In Beijing alone, 360,000 tons of water escape and leak every year.
We should learn from some good foreign methods, such as: carrying out "water resources education", raising people's awareness of water conservation, building pipelines to collect sewage from urban residents and public facilities, and urban sewage management. Recycle after secondary or tertiary treatment and purification, improve toilet flushing equipment, and adopt water-saving household equipment, so that we can better save water!

——A gift for the "Sixth Five-Year Plan" World Environment Day
Water is the source and foundation of life. Human health starts with water. Come. People can go several days without eating, but they cannot go several days without drinking water. Now, 2 billion people in the world are suffering from severe water shortage! In other words, water is the lifeblood of 2 billion people. And 50 million children die every year around the world because of drinking unclean water! This number is so shocking! The water crisis has sounded the alarm to mankind! Saving water and protecting water resources is the top priority now!
How important water is to us! If everyone pays attention to saving water, I don’t know how many people will benefit from it; on the contrary, if everyone wastes water resources without caring, then many people may suffer from drinking water difficulties! For example, if the water pipes in some public places leak, you can find someone to repair them, but if they are not repaired in time, it will be a waste of our drinking water. However, if the water is thrown out, it will never come back. This means that water resources are wasted. How inappropriate this is!
Some factories do not pay attention to protecting water resources and discharge industrial wastewater into rivers and lakes, causing pollution in many rivers and lakes. However, such results are compelling. If fish and shrimp drink such water, they will die; if humans use such water to bathe, they will get sick; if humans drink such water, it will be harmful to their health. The water ring is devouring the health of humans and animals! Just imagine, even if the factory employees make a lot of money, but the water is polluted, then people will have no clean water to drink. How will they survive then? What's the use of having so much money at that time? This is so harmful to others and not beneficial to oneself!
Some people have developed a bad habit of throwing garbage into rivers, lakes or other inappropriate places for temporary convenience. Just imagine, if each of us throws garbage into rivers and lakes, then a lot of water resources will be polluted; if everyone throws garbage randomly, then when it rains, the rain will wash the garbage into the rivers and lakes. , thus polluting the water resources we depend on for survival. How can we survive if a large amount of water resources are polluted? I think this bad habit is just for temporary convenience and will cause lifelong harm. It must be eradicated!
Now, due to the pollution of water resources in many aspects, and the pollution is getting more and more serious, there is less and less water for human beings to drink. However, without water, humans cannot live. This means that we must take active actions now to save and protect water resources. In order to save and protect water resources, I think everyone should put an end to the bad habit of throwing away garbage casually and throw garbage into the trash can; uncles and aunts in the factory must resolutely prevent industrial wastewater from flowing into rivers and lakes, and must conduct harmless treatment before discharging it. ; If there is a leak in the water pipe at home, you should find someone to repair it immediately; you should develop a good habit of saving water and not waste water resources casually (such as playing with water guns, water used for washing vegetables and clothes can be used to flush the toilet, etc.).
Let us join hands to save water and protect water resources! I believe that through the efforts of all of us, we will be able to do it!
Methods to save water
When taking a bath, first use the nozzle to wet the body from head to toe, then apply soap or body wash all over the body, and finally rinse it all at once. When washing your face or brushing your teeth, try to use a basin and cup instead of letting the faucet flow.
Wash when the washing machine is full of clothes. And, keep the water from the last rinse as the washing water for the next batch of clothes.
If you think the toilet water tank is too big, you can put a Coke bottle filled with water in the water tank to reduce the amount of water required each time.
Use one water for multiple uses. Use rice washing water and cooking water to wash dishes and chopsticks to remove oil and save water; use vegetable washing water, laundry water, and dishwashing water to water flowers and wash cars; after using face wash water, you can wash your feet, flush the toilet, etc.
When washing hands, washing in a basin saves more water than using a long flow of water. The same is true when washing vegetables, fruits or washing dishes. Continuous rinsing with the faucet on is very water-consuming. Intermittent rinsing can save water. . Save used water and use it again.
Washing machines in homes consume a lot of water. In order to save water, manufacturers and scientific researchers have made great efforts to save water as much as possible while ensuring clean clothes.
This inclined shape is not for beauty or novelty. The 10-degree inclined plane design has its own reasons. After the washing drum is tilted 10 degrees, its water level will be relatively deeper, which can achieve the washing effect of a larger amount of water. So it saves water.
The program set by the washing machine is generally one wash and two rinses. The water is mainly consumed in rinsing. If you don’t use washing powder, wouldn’t you be able to save rinsing water?
This ultrasonic washing machine can emit 20,000 shock waves per second, which can "shock" dirt from clothes. The washing machine is also equipped with a special electrolytic water device, which can decompose water molecules in tap water into hydrogen ions and oxygen ions, and use the ions to decompose and adsorb stains and dust to clean clothes. With a two-pronged approach, this washing machine that does not use washing powder can save more than 30% of water than ordinary washing machines.
Also, don’t set the water level in the washing machine too high, otherwise there will be a lack of friction between the clothes and the clothes will not be washed clean, but water will be wasted.
In addition to washing machines, toilets are also major water users in households, accounting for about 35% of residents’ water consumption. A family of three will flush more than 3,000 liters of water a month.
Technicians have developed a new type of toilet that uses only 4 liters of water each time, saving one-third to one-half of the water than the existing toilet.
Its water tank accumulates air while filling with water. It uses the pressure in the water supply pipe to compress the air accumulated inside, and then pushes the water to flow into the toilet at a higher speed. Different from the "pull" force of traditional sanitary ware, this new type of sanitary ware uses "push" force to discharge dirt, and the impact is large, so it can save water.
In fact, other domestic water in the home can also be used to flush the toilet. For example, after the last rinse, the clothes have been washed clean, and the water discharged from the washing machine looks relatively clean and flows directly into the sewer pipe. It's a pity. It would also be nice if the water used after washing your face and washing dishes could be reused. Amateur inventor Wu Hanping developed a domestic water reuse device and obtained a national patent. He connected the kitchen sink, bathroom basin and toilet cistern to a water storage tank. The relatively clean water flowing out of the sink and basin enters the water storage tank for toilet flushing.
Now let me teach you some tips for saving water: 1. Use a water-saving toilet, and install a 2-stage flushing accessory for a regular toilet. 2. Remove the floating cake at the bottom of the water tank to achieve stepless water control.
3. Shorten the flushing time of the automatic urinal flusher. 4. Use rice water, laundry water, dishwashing water, bath water and other clean water to water flowers, wash cars, and scrub floors. 5. Change the carpet cleaning method from wet or steam type to dry powder type. 6. Recycle the water collected by the dehumidifier and the waste water from water purification equipment such as pure water machines and distilled water machines for reuse.
Now that I have finished talking about the 6 water-saving secrets, do you think of a better way to save water than me? Are you saving water? I think you should be saving water!
For a long time, people have generally believed that water is "inexhaustible" and they do not know how to cherish it, but waste it.
In fact, water resources are becoming increasingly scarce, and our city's urban water supply is struggling to survive on the verge of serious water shortages. Tap water is hard to come by.
No one can live without water for a day. Water is the source of life. Cherishing water means cherishing your own life! Here, we introduce some common sense of water conservation in daily life:
Brushing teeth
Waste: Discharge water continuously for 30 seconds, using about 6 liters of water.
Water saving: use a mouth cup to collect water, a 3-mouth cup uses 0.6 liters of water. A family of three can save 486 liters of water per month by using it twice a day.
Laundry
Waste: The washing machine continuously fills, rinses and drains water, which requires about 165 liters of water each time.
Water saving: The washing machine uses washing-dehydration-water injection-dehydration-water injection-dehydration. It uses 110 liters of water each time and can save 55 liters of water each time. It can be washed 4 times a month and can save 220 water. Lift.
In addition, centralized washing of clothes can reduce the number of washes; hand washing of small items and small quantities of clothes is recommended, which can save a lot of water; excessive use of detergent will waste a lot of water.
Bathing
Waste: If you shower continuously for too long, a lot of water will be wasted.
If you put too much water in the bath and overflow it, or if you open the water plug and fill the bath with water at the same time, the waste will be staggering.
Water saving: intermittent water shower (such as foot-operated, induction type, etc.). Turn off the water in time when scrubbing. Avoid prolonged showers.
The water after bathing can be used for laundry, car washing, toilet flushing, mopping, etc.
Cooking
Waste: open the faucet wide and rinse for a long time. If you boil water for too long, a large amount of water vapor will evaporate. Rinse vegetables and fruits with tap water.
Water saving: Use paper to wipe off oil stains on cooking utensils and utensils before washing them to save water.
Control the flow rate of the faucet and change from uninterrupted flushing to intermittent flushing.
Car washing
Waste: Rinse with a water pipe for 20 minutes, using about 240 liters of water.
Water saving: Use buckets of water to wash the car, which requires 3 buckets of water and about 30 liters of water. Use washing water and laundry water to wash the car. Use a water-saving spray gun to rinse. Use mechanical automatic car washing and car wash water treatment and recycling.
Small ways to save water:
Saving water will benefit the present and serve the future. After discussion, students have worked out some small ways to save water in daily life:
1. Wash vegetables with rice water and then rinse with clean water, which not only saves water, but also effectively removes residual pesticides on vegetables;
2. Wash mops and floors with laundry water, and then rinse bathroom. The second step is to use laundry water to clean clothes, wipe doors, windows and furniture, wash shoes and socks, etc.;
Third, flush the toilet after defecation and urination, try not to turn on a large water pipe for flushing, and make full use of the used "dirty water" ”;
4. In summer, sprinkle water on indoor and outdoor floors to cool down. Try not to use clean water, but use laundry water after washing;
5. When cleaning bicycles and family cars, do not use water To flush, use a damp cloth instead. For areas that are too dirty, use the remaining water after washing clothes to rinse;
6. Flush the toilet: If you use water-saving equipment, you can save 4 tons of water each time 5kg;
7. When watering flowers at home, it is advisable to use rice water, tea water, laundry water, etc.;
8. Use a small amount of water for washing hand towels, small objects, fruits, etc. at home. It is better to use a basin to hold water rather than open a faucet to rinse;
9. Wash the floor: scrub with a mop, which can save more than 200kg of water per household each time compared to flushing with a faucet;
10. . If the faucet leaks after being used for a long time, you can use the rubber cover of the small medicine bottle containing penicillin to cut a gasket that is the same as the original one and put it in to ensure that water does not leak;
11. Remove the float ball of the water tank in the bathroom Adjusting it downward by 2 centimeters can save nearly 3kg of water per flush; assuming that a family uses it four times a day, 4380kg of potion can be saved in a year.
12. Wash vegetables: wash basin by basin, do not open the faucet, you can save 50kg per meal;
13. Shower: If you turn off the faucet and wipe Soap and one bath can save 60kg of water;
14. Washing clothes by hand: If you use a wash basin to wash and clean clothes, you will save 200kg of water each time than leaving the faucet on;
15. Use a washing machine to wash clothes: It is recommended that you fill the bucket before washing. If you wash it twice, it will consume 120kg more water;
16. Car washing: scrubbing with a rag is better than rinsing with a faucet. At least 400kg of water can be saved each time;

Cherish water resources
Zhaoqing No. 16 Primary School
·Summary of content
Water is the source of life. On which billions of lives depend. People continue to waste water resources, but very few people do it. Although nearly 5/9 of the earth is covered with water, 97% is inedible seawater, and of the remaining 3% of fresh water, only 1/3 is drinkable. This shows how precious water is.
·Introduction
"Water is the source of life, and we must protect every drop of water." This sentence is correct. If there is no water, the earth will dry up; if there is no water, the earth will dry up; Without water, we humans may die of thirst; without water, there would be no such beautiful world of ours. We must cherish every drop of water and every tear of Mother Earth.
If there is no water, we can’t wash our faces, brush our teeth, or quench our thirst. There will be no fish and shrimps on the table, we can’t see flowers and trees, and we don’t know what swimming is. All ships will be scrapped, concrete blocks will not be built, and high-rise buildings will not be able to swim. Jian, even the little baby has no tears when he cries... In short, water is very precious. But often many people don't know how to cherish it. Water was flowing from the faucet, but the person was nowhere to be found; when taking a shower, a large vat of water was poured in, soaked for ten minutes and then left to flow away...
So, our technology team I decided to conduct investigation, analysis, and write a paper, and at the same time called on people to save water and protect water resources.
1. Investigation and analysis of the overall water consumption situation of Guangdong people
The water usage habits of most of our Guangdong people can be summarized in two words - waste. It is reported that the comprehensive water consumption per capita in Guangdong in 2007 was 493 cubic meters, while the national comprehensive water consumption per capita in 2007 was only 438 cubic meters. In the minds of ordinary people, Guangdong is located at the southernmost tip of mainland China, with abundant rainfall and abundant water resources. Therefore, Guangdong people have long formed the habit of using water as they want without worrying about it. Regardless of agriculture, industry, or urban domestic water use, there is serious waste. Water quotas for various industries are generally higher than other provinces. However, the actual water resources available are not high. According to reports, the current per capita water resources in Guangdong is 2,118 cubic meters, which is less than the national per capita level of 2,200 cubic meters and only equivalent to a quarter of the world's per capita water resources. In recent years, the frequency of drought and water shortage has increased significantly than in the past. Especially when coastal areas suffer from drought, the water level of rivers often drops, causing salt tide disasters to take advantage of the situation.
Therefore, the water shortage problem has become an important constraint for Guangdong to achieve the goal of a comprehensive moderately prosperous society and continue rapid and sustainable economic development in the next 20 years.
Similarly, there is a water-wasting action that we all often do. Nowadays, we see that many stores use sterilized tableware wrapped in plastic for customers to use, but some diners still habitually rinse it with hot tea before using it. This is a waste of water. Regarding this habit, if we look at it from the perspective of water conservation, it is a very big waste. If calculated as 1/8 liter of a cup of water, 8 customers will use 1 liter. 8,000 customers is 1 ton of water, which is 1 cubic meter of water, and 80,000 customers is 10 cubic meters of water. According to Guangzhou's permanent resident plus floating population at the beginning of last year, it had reached 12 million people. A rough calculation shows that if each person goes to a restaurant to eat once a day, 1,500 cubic meters of water will be wasted just for rinsing tableware, which amounts to 547,500 cubic meters of water in a year.
Of course, Cantonese people are gradually becoming more economical. He Guoqing, deputy director of the Hydrology Bureau of Guangdong Province, and other experts talked about building a water-saving society at a water use event on the 11th of this month. They believed that Guangdong has great potential and broad prospects for water conservation. The first is the potential for industrial water conservation. Currently, Guangdong's industrial water intake quota is high, the reuse rate is low, and leakage and leakage are serious. The national industrial water reuse rate is about 55%, while that in developed countries is 75% to 85%. The reuse rate across Guangdong is generally only 20% to 40%. Therefore, experts believe that the main channel for industrial water conservation is to strengthen water conservation in key industries such as thermal power generation, chemical industry, papermaking, metallurgy, textiles, building materials, food, etc. Secondly, there is the potential for agricultural water-saving. The utilization rate of agricultural irrigation water in the province is only about 40%, while it reaches 70% to 80% in advanced countries. The area of ??Guangdong’s water-saving irrigation projects accounts for less than 1/3 of the effective irrigation area, and the anti-seepage rate of channels The irrigated area using advanced water-saving measures such as sprinkler irrigation and drip irrigation is very small. Experts believe there is much potential in this regard.
3. Investigation and analysis of common water waste situations
1. Due to backward management level and low economic strength, advanced water technology, equipment, processes and management methods are not available. use. For example, farmers in many places in our country still cling to the old concept of using flood irrigation and filling the entire field with water. In some places, one ton of water is used to produce one kilogram of rice. In addition, our country's production technology is backward, industrial production requires huge amounts of water, the water reuse rate is low, and water consumption is large.
2. The maintenance and replacement of water-saving equipment and facilities is not timely, resulting in a waste of water. For example, due to disrepair, urban water supply pipelines leak during the water delivery process; managers forget to turn off the faucets due to negligence; household faucets are not closed tightly, causing water leakage, etc.
3. Failure to use water-saving facilities or water-saving devices causes waste. Some people are reluctant to replace water-saving appliances, but in fact the extra water bills they pay are enough to purchase water-saving appliances. Nowadays, there are more and more types of water-saving appliances. Take toilets as an example. Old-style toilets waste 4-5 kilograms of water each time than water-saving toilets, and drain 3 to 25 tons of water a month. If there are 200,000 toilets , 50 million tons of water will be lost a year.
4. The water-saving system is not perfect, the management level is low, and the implementation is weak. Some water-using units take advantage of loopholes in the system, resulting in wastage of water.
5. People’s weak awareness of water conservation is the most fundamental reason for wasting water. If each of us pays a little attention, we can save at least 1 kilogram of water per person per day.
6. In households, it is not surprising that water is wasted. When some people use water, they like to open the faucet very loudly and rinse for a long time, which wastes a lot of water. It is also common for some people to waste money by "loving the new and hating the old" when storing water. But human beings are still unable to realize how many precious lives on the earth will be lost due to their so-called "favouring the new and hating the old".
7. In schools, water waste is even more common. Usually, some students always forget to turn off the faucet after using water; when taking a bath, they flush like crazy for their own temporary happiness. Your own negligence not only brings inconvenience to others, but also reaps the consequences. During the peak shower period, water outages often occur. But this has always been the case, why bother in the first place? After investigation, our school consumes a lot of water and is wasted seriously. The boys' dormitory is often short of water. If this continues, there may be serious consequences.
8. In agriculture, water resources are also seriously wasted.
According to data, 2004 was the most severe drought in 26 years. It was difficult to get a rain. As of early February this year, the drought-stricken area of ????crops in the province reached 2.71 million acres, accounting for 43.34% of the cultivated land area. 291,600 people and 112,800 large livestock have difficulty drinking water. However, in most areas, water conservancy is still opened arbitrarily and irrigation is unreasonable.
Faced with this situation, can humans have the heart to treat the liquid of life like this? Can you bear to let this beautiful water ball dry up? Are you willing to turn a blind eye like this? So let’s work together to find ways to save water.
IV. Measures and Suggestions
(1) Methods and measures for saving water
①. Bathroom water
1. Bathing Using a shower can save at least 50% of water consumption, about 50 liters, compared with a bathtub.
2. Use low-flow shower heads, such as installing a "water saver" on the shower head, which can not only save 50% of water consumption, but also save energy consumption of water heaters.
3. Do not throw away the water after bathing. It can be used for flushing the toilet, washing clothes, watering flowers, etc.
4. When filling water, prevent excess water or overflow and loss.
5. Faucet water saver can be installed.
6. Develop a good habit of turning off the faucet whenever you are not using water. Check whether the faucet is completely closed before going to bed or when leaving home.
②. Sanitary water
1. Bottles of appropriate size can be placed in the toilet box to reduce water consumption.
2. Adjust the float height to control the water output.
3. Use other stored water to flush the toilet.
4. Install a water-saving toilet, or install a two-stage flushing accessory on an existing general flush toilet.
5. If there is leakage in the toilet or water tank, please ask someone to repair it as soon as possible.
6. Do not throw tissues and other items into the toilet to increase water consumption.
③. Laundry water
1. Control the amount of clothes to avoid too much or too little in the washing machine.
2. When washing for the first time, only remove water once before washing, which can save water and washing time.
3. Choose the appropriate washing time according to the type of clothes.
④. Reuse of water
1. When washing dishes, vegetables, or laundry, do not flush directly at the faucet. Instead, put an appropriate amount of water in the basin to reduce water use.
2. The water used for washing rice and cooking noodles can be used to wash dishes and chopsticks.
3. Vegetable washing water, laundry water, dishwashing water and bathing water can be used to water flowers, wash cars and mop floors.
4. The water collected by the dehumidifier and the waste water from water purification equipment such as pure water machines and distilled water machines can be recycled and reused.
5. Food that needs to be defrosted can be taken out of the refrigerator as soon as possible, or defrosted in a microwave oven to reduce water consumption.
