Among household water consumption, laundry water consumption accounts for a large proportion of the total water consumption. Whether it is hand washing or machine washing, the general method is to first use a small amount of water and detergent (soap\washing powder, etc.) to wash away the stains, and then rinse it with clean water several times. The water consumption mainly occurs in the rinsing stage. In order to achieve the desired results during the rinsing process, To keep things clean and save water, here are a few tips:
Selected cleaning programs
When washing a small amount of clothes in the washing machine, the water level is set too high, and the clothes will float in the high water. Floating back and forth, there is a lack of friction between them, so they cannot be washed clean and water is wasted. At present, in terms of program control of washing machines, washing machine manufacturers have developed more washing machines with water level sections, refining the water level sections, and reducing the washing start water level by 1/2; the washing function can be set to the first clean, second clean or third clean function. , we can choose different washing water levels and cleaning times according to different needs, so as to achieve the purpose of saving water.
Soak in advance to reduce water consumption
The washing time can be determined by the type of fabric and the degree of soiling of the clothes. Soaking clothes before washing can reduce the number of rinses and reduce the water consumption of rinses.
Add an appropriate amount of washing powder
The amount of washing powder (that is, the concentration of washing powder in the water when the washing machine is at the appropriate water level) should be mastered. This is the key to the rinsing process and also The key to saving water and electricity. Taking a washing machine with a rated washing capacity of 2 kg as an example, a low-water level, low-foaming detergent requires about 40 grams when the washing capacity is small, and about 50 grams when the water level is high. Calculated based on dosage, the optimal washing concentration is 0.1 to 0.3. The solution with this concentration has the greatest surface activity and better decontamination effect. There are many varieties of laundry detergents on the market with different functions, and you can choose according to your family's habits. Putting too much washing powder will inevitably increase the difficulty and frequency of rinsing.
Wash clothes together
If there are too few clothes, don’t wash them. If you have more clothes, wait and wash them together. This is also a way to save water.
Make full use of rinsing
(1) Increase the number of rinsing times. The amount of water for each rinse should be less but not too much, so as to basically submerge the clothes. (2) Use the same amount of rinsing water each time. (3) After each rinse, wring the clothes as dry as possible and then add clean water. (4) If the rinsing water is retained as washing water for the next batch of clothes, 30-40 liters of clean water can be saved at one time.
In the scorching sun, the number of times we take showers has greatly increased. How can we save our bath water?
Use a shower head to take a shower: Using a shower head to take a shower saves up to 80% of the water than using a bathtub to take a bath. Therefore, it is recommended that everyone use showers more often and less or no bathtubs.
(1) Learn to adjust the ratio of hot and cold water.
(2) Avoid showering for too long when taking a bath, and turn off the water in time when scrubbing; do not leave the water on the nozzle all the time, let alone leave it open.
(3) Wet it from head to toe as much as possible, then apply soap and scrub the whole body, and rinse thoroughly for the last time. Do not wash your hair, upper body, lower body and feet separately.
(4) When taking a bath, you must concentrate on taking the time and do not take it leisurely or chat while washing. Don't even have a big fight with your best friends in the bathroom. Remember: time is water!
(5) Do not use the opportunity of taking a bath to wash clothes and shoes "by the way".
When taking a bath in the bathtub, be careful not to fill it with water. 1/3-1/4 basin is enough. The water after bathing can be used for multiple purposes, such as flushing toilets and mopping floors.
Other tips for saving water at home:
What to do if the toilet leaks
A common cause of toilet leaks is that the hemispherical rubber cover that covers the drain is too small Light. After the water tank is drained, the gravity is not enough and it is not tight enough when it falls, causing water leakage. It often needs to be repeated many times to seal it tightly. The solution is to tie some heavy objects, such as large nuts, toothpaste rinds, etc., to the connecting rod connected to the rubber cover. Pay attention to the bundled objects as close as possible to the rubber cover, so that the rubber cover can more easily cover the drain outlet, and the leakage problem will be solved. .
Use water-saving appliances
Families with the conditions should replace water-saving sanitary appliances. It is recommended that everyone install and use water-saving water appliances or sanitary ware, and use ceramic chip sealed faucets. , eliminate the screw-lift iron faucet, transform the toilet water tank of more than 9 liters, and use the toilet water tank of no more than 6 liters. For existing non-water-saving toilets, you can try placing a brick and a salt water bottle in the water tank to reduce the amount of flushing water.
Domestic water
Domestic water should be used in series as much as possible. One water can be used for multiple purposes. For example: rice washing water can be used to wash vegetables. It is also helpful for removing pesticides on the surface of vegetables. Vegetable water can also be used for flushing the toilet; bath water, laundry water, and face (feet) water can be used for mopping the floor and flushing the toilet.
It is advocated that one household has one meter to reduce the leakage rate of the pipe network behind the meter.
In areas with high water pressure, residents may wish to control the water pressure by adjusting the tap water valve, which can save a considerable amount of water.
Never turn the tap on for long periods of time to wash hands, laundry or vegetables. When washing vegetables and fruits, the flow rate of the faucet should be controlled, and washing with regular running water should be changed to intermittent washing.
Repair dripping faucets and other water appliances promptly. Leaking faucets can consume 70 liters of water per day.
People’s suggestions: Using water-saving appliances can effectively save water
Mr. Zhang, who has always been concerned about water-saving issues, believes that it is necessary to develop and promote some low-priced water-saving appliances and Unified installation in each residential area is an effective way to save water in Beijing. Mr. Zhang said that he had a water-saving invention, changing the ordinary toilet into a two-stop toilet. The large water can be controlled at 6 to 9 liters at a time, and the small water can be controlled at 2 to 3 liters. Different ones can be selected according to different situations. Toilet water level.
Another citizen, Zhang Xueliang, said that he invented a water-saving faucet that can automatically close even if you forget to turn off the faucet after using water. This patent is currently being trialled at Capital Airport and Miyun.
Mr. Hu suggested that wastewater recycling water-saving devices can be installed in residential buildings. After the domestic sewage is filtered and deodorized by the water-saving device, it can be directly used for flushing toilets. As a result, residents' monthly domestic water consumption can be reduced by approximately 30%. In addition, it can effectively reduce sewage discharge and reduce the burden on the urban sewage treatment system. Mr. Rong suggested that the water in many Tongzi buildings in Beijing is still public. It is possible to separate the public water in Tongzi buildings and equip public faucets with private keys that can record water consumption, so that who has used how much water can be seen at a glance.
Mr. Cheng said that when watering many green spaces now, they often use rubber water pipes to irrigate directly. This not only wastes water resources, but also easily causes the sidewalks next to the green spaces to be filled with water. In fact, the water-saving sprinkler irrigation method for green spaces now being vigorously promoted in some areas in Beijing is very advanced. In addition, the drip irrigation method adopted by Israel for green spaces is also very helpful in saving water.
