Beijing's water saving goal in 2005 is 40 million cubic meters. Jiao Zhizhong, director of the Municipal Water Affairs Bureau, announced seven water-saving plans: first, new and expanded projects must be equipped with reclaimed water utilization facilities at the same time, and metering management should be fully implemented; Second, the industry should set water consumption quotas, and large households with annual water consumption of more than one million tons should sign water supply agreements; Third, the water consumption index of social units should be further compressed10%; The fourth is to complete 35 industrial water-saving technological transformations, and Yizhuang will build a water-saving demonstration zone; Fifth, popularize household water-saving appliances, and 50% of households will switch to water-saving appliances during the year; Sixth, newly installed reclaimed water pipeline 100 km during the year to expand the scope of reclaimed water users; Seventh, continue to select water-saving models, and every citizen can strive to be a water-saving model.
Water-saving scheme of enterprise units
We have designed a set of water-saving schemes for enterprises. After implementing this scheme (or taking one of the measures in this scheme), we guarantee that you will receive good water-saving effect, save energy, reduce expenses and reduce labor force for you, thus improving work efficiency and getting twice the result with half the effort.
Step 1: Carry out water balance test, which is the most scientific method to find out the water use situation of enterprises (units). After the water balance test, the number and usage of water pipes and appliances in the unit, the daily, monthly and annual water consumption, and the water consumption of various water points (such as boilers, bathing, car washing, swimming, etc.). ) You can clearly check through the test, and find out the reasons for unreasonable water use through the analysis of water consumption data, so as to take corresponding measures. Please visit the "Water Balance Test" section of this website for specific methods and steps of water balance test.
Step 2: Ask for water from scientific management. Formulate a scientific water use system, take measures such as index decomposition, responsibility to people, saving rewards and punishing inferior ones, and fully mobilize people's enthusiasm. This is the basis of water-saving work. For specific experience, welcome to visit and study in "Northern Transportation Energy Saving Service Center".
Step 3: Ask for water from science and technology and use water-saving appliances so that water cannot be wasted. The specific method is as follows:
1. faucet with ceramic chip, variable distance, self-closing and high-tech content. This faucet not only has no water leakage and long service life, but also has the characteristics of short opening and closing time, water loss prevention, automatic closing without water pressure and so on, and all of them have a warranty period of more than three years.
2. The urinal (bucket) adopts infrared water-saving controller, which can stop the flow when people come, which can not only achieve the effect of cleaning without odor, but also save water by more than 70%.
3. Toilet squat pit adopts foot valve, which is not only sanitary, but also convenient to use. "Wu Fang" brand fittings can be used for high containers, and different flushing volumes can be used for defecation and defecation, saving water by 50%.
4. Water the lawn with "micro-spraying system". Micro-spray saves water by 80% compared with flood irrigation and 50% compared with ordinary large spray, and it has low cost and long service life.
5. The bathroom shower head adopts diaphragm pedal shower head, which fundamentally prevents dripping and water leakage, and the use effect is very good.
6. The swimming pool adopts circulating water treatment equipment, which basically does not need to replenish water.
7. Construction of "reclaimed water treatment project". Sewage, such as bath water, laundry water, vegetable washing water and toilet flushing water, is collected, filtered, precipitated, biochemical and disinfected by the reclaimed water treatment station, making it a reusable water source. The treated water can be used to water green spaces, wash cars, spray playgrounds and flush toilets. The construction of reclaimed water treatment station in general units costs little, but it has achieved great results, especially in today's rising water charges, which is really cost-effective.
Family water saving plan
We designed a water-saving scheme for the family. After implementing this scheme (or taking one of the measures in this scheme), we guarantee that you will receive good water-saving effect, save energy, reduce expenses and reduce unnecessary troubles (such as water leakage, noisy people, flooded furniture, etc.). ).
For families, there is generally no problem of wasting water casually. After all, you have to pay for it yourself. The main problems are: first, the consciousness of saving water is not strong; Second, water appliances are backward; Third, I don't know what water saver to use and where to buy it. Here are some household water-saving appliances.
1. Bathroom water saving: According to statistics, bathroom water accounts for more than 50% of household water consumption, mainly due to unreasonable structure and waste of water. Toilets are divided into 15 liters, 9 liters and 6 liters according to their capacity. 15 liters of the country has been clearly eliminated, and now 6 liters of toilets are vigorously promoted. However, because the 6-liter toilet is a systematic project (involving bucket structure, material smoothness, inclination angle, etc. ), can be used in new buildings, not in old buildings, because it is difficult to wash with less water, and it is for users to replace. According to the structure, it can be divided into straight drop type, flap type, siphon type, hydraulic type and differential pressure type. The straight plate type has been explicitly eliminated by the state, and now most users use the flip plate type. The new toilet combines siphon and pressure difference, as well as toilet seat and urinal seat, achieving the purpose of saving water. So what should the toilet do to save water?
1. A full set of new ones. It is suggested to choose two-stage siphon pressure difference water-saving toilet. This kind of sanitary ware not only saves water, but also is very convenient to use. Old people and children can use it. This method costs a lot, it can be done around 400 yuan, and it can be installed at home.
2. Do not replace the water tank and bucket, only replace the water tank accessories. This is also a good idea. 48 yuan's Li brand and 88 yuan's Zhonghua Ding brand are also patented products, which save 50% water and have a three-year warranty. It is also worth changing.
Without changing anything, you can get twice the result with half the effort by taking a few measures. (1) Adding a small plastic-coated spring to the racket can not only make the racket more airtight, but also control the water consumption by yourself. If you want to use half a box, you can use one box. According to estimates, after using water-saving springs, water can be saved by 20-40%. Don't underestimate this small spring, it is also a patented product, 3 yuan money will solve the problem, and the installation only takes half a minute; (2) Fill the water cup and coke bottle with water and put them into the water tank. I don't need to tell you that you will understand the truth. Of course, bricks can also be used.
Second, the faucet saves water. The old rotary faucet can't be used, which is a waste of water and labor, and the valve stem is easy to seep and get dirty, not to mention how uncomfortable it is.
High-tech faucets with ceramic plates, variable distance and self-closing are adopted. These faucets not only have no leakage and long service life, but also have the characteristics of short opening and closing time, water loss prevention and self-closing without water pressure, and all have a warranty period of more than three years. What should I do if I forget to turn off the tap after stopping the water? The furniture was washed away, the household appliances were soaked, and the neighbors came. What a nuisance. Don't worry if you install a safe self-closing faucet. It will automatically turn off after stopping using it, and there will be no drop of water coming out. There is absolutely no need to worry about the time when the water overflows Jinshan after use, and it can be opened at 360 degrees and rotated at any angle, which is very convenient and hygienic. There is also a variable distance faucet. With this faucet, the past drip flow and line flow can't be discussed at all, but the friend who stole water by this means is sorry, and its closing speed is only 0. 16 seconds (others need 1-3 seconds). Don't underestimate this time. As time goes on, the water saved is considerable.
Third, air conditioning saves water. Air conditioning can also save water, don't make a mistake? Yes, but it should be "making" water. Listen: summer is burning, every air conditioner is running, and the poor neighbor is miserable and can't sleep. The problem of air conditioning dripping has been bothering us for many years. If you lead the drain pipe to your home and connect it to a bucket, the problem will be solved, and the amount of water is still considerable, and you will receive a liter of water in 2 hours. The water can be used for watering flowers, washing hands and flushing toilets. Neighbors are happy, too. Is this a good idea?
