Now that I have finished six secret recipes for water saving, have you thought of a better way to save water than me? Are you saving water? I think you should save water!
For a long time, people generally believe that water is "inexhaustible". If you don't know how to cherish it, you will waste it. In fact, water resources are increasingly scarce, and the urban water supply work in our city is struggling on the edge of serious water shortage, and tap water is hard to come by.
People can't live without water for a day. Water is the source of life. Cherishing water means cherishing your own life! Here, we introduce some water-saving common sense in daily life:
Brush your teeth/teeth
Waste: continuously drain water for 30 seconds and use about 6 liters of water.
Water saving: cups are connected with water, 3 cups use 0.6 liters of water. A family of three can save 486 liters of water twice a day.
wash clothes
Waste: The washing machine continuously washes and drains water while filling water, which requires about 165 liters of water each time.
Water saving: the washing machine adopts the washing-dehydration-water injection-dehydration-water injection-dehydration mode, and the water consumption is 1 10 liter each time, which can save 55 liters and 220 liters each time.
In addition, centralized laundry can reduce the number of laundry; Hand washing is advocated for small pieces and a small amount of clothes, which can save a lot of water; Too much detergent will waste a lot of water.
have a bath
Waste: A long uninterrupted water shower will waste a lot of water.
Too much bath water, or even overflow, or open the water plug and inject water at the same time, the waste will be amazing.
Water saving: intermittent water shower (such as pedaling, induction, etc.). ). Turn off the water in time when scrubbing. Avoid taking a long shower.
The water after bathing can be used for washing clothes, washing cars, flushing toilets and mopping floors.
cook
Waste: the tap was left on for a long time. Boiling water for too long, a lot of water vapor evaporates. Rinse vegetables and fruits with tap water.
Water saving: oil stains on cookware and tableware can be wiped off with paper before washing, which can save water.
Control the flow of the faucet, and change the uninterrupted flushing into intermittent flushing.
wash a car

A faucet that doesn't close tightly drains 1 to 6 cubic meters a month, and a leaky toilet drains 3 to 25 cubic meters a month. It hurts to waste all kinds of domestic water! Experts say that if all urban households in China replace toilets or showers with water-saving products, it is estimated that 490 million tons of water can be saved every month. In the face of frequent water emergencies in China, every family's water-saving action is indispensable for building a conservation-oriented society.
Water-saving washing machine: 7 14 Kunming Lake can save one year.
In fact, there is a lot of hidden waste of domestic water. Taking Beijing as an example, a survey conducted by Beijing Water Conservation Office shows that the domestic water consumption of Beijing residents seriously exceeds the standard, and users who consume more than 8 tons/month account for 50% to 80% of the total users, among which household laundry water waste accounts for a considerable proportion.
According to statistics, laundry water accounts for 1/3 of all household water consumption. In general, most of the water used by ordinary washing machines for washing clothes at one time is between 150- 180 liters. At present, there are about 65.438+0.2 billion washing machines in urban society in China. Roughly estimated by the frequency of use three times a week, the annual water consumption of all washing machines is at least 3 billion cubic meters. If all these washing machines are replaced by water-saving washing machines, about 7 14 Kunming Lake or 93 Huairou Reservoir can be saved a year.
But among all water-saving products, washing machine is the most easily overlooked. In the water-saving technology of washing machines, many manufacturers have invested money and manpower in R&D transformation and launched a series of products. But so far, water saving has not become the core element for consumers to buy washing machines. Experts analyzed the reasons: First, the water-saving of washing machines did not cause visual impact to residents, and their awareness was not strong; Second, residents have the concern of "saving water, so the cleanliness of laundry will be reduced".
3/6 liter double-key toilet: a family saves nearly 2000 liters of water every month.
Flushing the toilet is inseparable from boiling water. In the past, a toilet needed about 10 liter of water for each flush. Take Beijing as an example, and make a simple calculation:
Beijing residence 1 10,000 sets. If you use the toilet six times a day, the daily water consumption is about 60 liters, which is 210.6 million tons per year. This should be a serious problem for Beijing, which is very short of water resources.
According to Yue, a senior engineer of the bid-winning certification center, the water consumption in toilets accounts for 60% to 70% of the household water consumption, and the large water tank in toilets is an important reason for the large water consumption. In April 2000, China Building Decoration Association formulated the industry standard "6-liter toilet supporting system" (JC/T856-2000), which is a powerful measure to save water in toilets. A building materials salesman told reporters that ordinary toilets with a displacement of 8 liters are not selling well at present, and water-saving toilets below 6 liters are more popular. Among them, the "two-gear" double-spoon toilet (a toilet with 3 liters or 6 liters of water as required) has become the mainstream product.
How much water can be saved by controlling the water quantity through the double-key toilet? Yue calculated an account for the reporter:
Calculated by three people in each family, each person washes 4 times a day. Take a 9-liter toilet as an example, the monthly water consumption is about 3240 liters. If you use a 3/6 liter toilet, it will be 1350 liters per month, which not only saves 1890 liters of tap water, but also reduces the discharge of 1890 liters of sewage.
Water-saving faucet: 200,000 times without water leakage.
According to the data of Beijing Water Saving Management Center, the waste of "running and leaking" caused by the faucet not being closed tightly is amazing. According to the measurement, Didi can collect 3.6 kilograms of water in one hour and 2.6 tons of water in one month. If it is a continuous line of small water flow, it can collect 17 kg per hour and 12 tons per month.
The popularization of water-saving appliances, including water-saving taps, is imminent, but the situation is not optimistic. Take Beijing as an example. At present, the total penetration rate of household water-saving appliances in the city is only 30%, and there are still water-saving faucets "sleeping" in the market.
Yue said that not all water-saving faucets with special functions, whether they are dual-control, induction, pedal or self-closing water-saving faucets with special functions, must first look at the quality of the faucets.
"The key to the quality of the faucet lies in the valve core. At present, the faucets on the market mainly use rubber valve core, ball valve core and stainless steel valve core, among which stainless steel valve core is a new generation of valve core material with the characteristics of good sealing and long service life. In addition, a good faucet should be cast as a whole. It feels heavy in your hand, and it sounds dull when you knock. If the sound is brittle, it is probably made of stainless steel. The quality of this faucet is one grade worse than that of copper faucet. " Yue said to him:
Yue said that whether the faucet saves water is mainly judged by the water flow data of the faucet. Generally speaking, the flow rate of water-saving faucet is 9 liters/minute, and it will not leak after being used for 200,000 times. According to the frequency of ordinary life use, it can be used for at least 5 years.
Yue introduced that at present, relevant water-saving faucet certification units have been established in China, and water-saving faucets can be identified by certification marks with the word "clean". In addition, some high-end brands of faucets reduce the actual water flow of faucets by increasing the air content and pressure in the water flow, that is, the "softening system" to achieve the purpose of saving water. However, this kind of faucet also has problems such as decreased sensitivity after long-term use, which is more difficult to maintain than ordinary faucets, and consumers should consider it.
Get rid of bad water habits: it can save water by about 70%
Ordinary families have many bad water habits. For example, use the toilet to flush cigarette butts and break garbage; Wash potatoes and carrots before peeling; Rinse the vegetables before picking them; Open the door, answer the phone and change the TV channel without turning off the tap when using water; Forget to turn off the tap when stopping water, and the water flow is unattended when coming; Wash your hands, brush your teeth, wash your face without turning off the tap and so on. According to the analysis of water-saving experts, as long as we get rid of these bad habits, we can save about 70% of water, not only saving money for ourselves, but also saving water resources for the society.
What are the tricks for household water saving? We have combined the opinions of some experts:
Multi-purpose of one water: you can wash your feet after using the face washing water, and then flush the toilet; A vat for collecting waste water should be prepared at home to collect domestic waste water such as washing clothes, flushing toilets and mopping the floor. Such a family of three can save about 1 ton of water every month.
Washing dishes and chopsticks with rice washing water and boiled noodles can save domestic water and reduce detergent pollution; Washing water such as vegetable washing water, washing water, dish washing water and bath water for watering flowers and washing cars; Watering flowers with water from fish farming can also promote the growth of flowers and trees.
When washing fruits and vegetables with detergent, you need to rinse them with clear water several times before you dare to eat them safely. It can be disinfected by soaking in salt, and washing once is enough.
If you think the water tank of the toilet is too big, you can put a brick or a coke bottle filled with water vertically in the water tank to reduce the amount of water flushed each time. However, it should be noted that bricks or coke bottles should not interfere with the movement of water tank components. However, these fillers sometimes prevent the physical objects from being washed away, or cause water pipes to be blocked, causing safety hazards. Especially for toilets under 6 liters, there is no need to put these things.
The glaze quality of toilet or washbasin will affect the water consumption. Products with fine and smooth glaze, uniform glaze color and low water absorption can save water when washing and can be cleaned at one time. It can be verified by experiments, such as dropping a few drops of red liquid on the glaze and drying it with a wet cloth after a few seconds. It is best to have no dirty spots on the glaze.
Drop a few drops of food coloring into the water tank and wait for 20 minutes (make sure no one goes to the toilet during this time). If colored water flows into the toilet, it means that the water tank leaks.
Turn off all faucets and make sure that there is no water and the water meter is still moving during this time, indicating that the water pipes in the house or underground are leaking; It's still dripping after the tap is turned off. Change the rubber pad quickly.
Replacing the fully rotating faucet with 1/4 rotating faucet can reduce the water loss by shortening the on-off time of the faucet;
In winter, special attention should be paid to the inspection of water pipes to prevent water pipes from breaking: the covering sand washed away by floods in rainy season should be filled in before winter to prevent water pipes from being damaged by shallow freezing; Outdoor faucets and water pipes should be equipped with anti-freezing equipment (anti-freezing bolts, anti-freezing wooden cases, etc.). ); Where there is ice at home, it should also be wrapped in sacks and wrapped with straw ropes; Once the water pipe freezes, don't bake it with fire or burn it with boiling water, which will damage the water pipe and faucet due to sudden expansion. You should wrap the faucet with a hot towel to help thaw it.
Use a low-flow shower nozzle when taking a shower, or install a slow-flow faucet vaporizer.
Change the bath into a shower, use a low-flow shower head to avoid taking a long shower; When many people take a shower, don't keep one after another, which can save the loss of cold water before the hot water flows out.
Wash the car with a hose with a plug or scrub it with a bucket and sponge rag.
Control the appropriate amount of clothes to avoid too much or too little clothes in washing machines and dishwashers; Choosing a washing machine with automatic water regulation, dewatering once before washing and cleaning can save water and cleaning time; If you leave the rinsing water to the next batch of washing water, you can save 30 to 40 liters of clean water at a time.
