Saving water is beneficial to the present and will make great contributions to the future. After discussion, the students came up with some ways to save water in life:
1. Washing vegetables with rice-washing water and then with clear water not only saves water, but also effectively removes pesticide residues on vegetables;
Second, wash the mop, sweep the floor, and then flush the toilet. The second washing water for washing clothes cleans doors and windows, furniture, shoes and socks, etc.
Third, flush the toilet after urinating, try not to open the big water pipe for flushing, and make full use of the used "dirty water";
4. Sprinkle water on the indoor and outdoor ground in summer to cool down, try not to use clear water, and use washing water after washing;
5. When cleaning bicycles and family cars, don't wash them with water, but wipe them with a wet cloth. If it is too dirty, wash it with the water left over from washing clothes.
6. Flushing the toilet: If you use water-saving equipment, you can save 4-5 kilograms of water each time;
Seven, family watering flowers, appropriate use Taomi water, tea, laundry water, etc. ;
Eight, household washing towels, small objects, fruits and other small amounts of water. It is advisable to use a basin to hold water instead of turning on the tap to flush;
9. Washing the floor: scrubbing with a mop can save more than 200 kilograms of water than washing each household with a faucet;
Ten, faucet used for a long time leaks. You can cut the rubber cover of the small penicillin bottle open to ensure no water leakage;
1 1. Adjust the floating ball in the toilet water tank down by 2 cm, saving nearly 3 kg of water each time; If you use it four times a day at home, you can save 4380kg of medicine a year.
Twelve, washing vegetables: a pot of a pot, do not run the faucet, a meal can save 50kg;;
13. Shower: If you turn off the tap to wipe soap, you can save 60kg of water by taking a shower;
14. Hand-washing clothes: If you use the washbasin to wash clothes, you will save 200kg of water each time compared with turning on the tap;
15. Washing clothes with a washing machine: I suggest you fill a bucket before washing. If washed twice separately, it will consume120kg; More water.
Sixteen, car washing: scrubbing with a rag can save at least 400kg. Compared with washing with a faucet, the water consumption is much less each time;

Small measures to save electricity
Although these are small measures to save electricity, in the face of serious power shortage, as long as we can start from small things and start from ourselves, we can tide over the difficulties and support the good development of local economy.
The set temperature of the air conditioner should not be too low, and it is best to set it at 27 to 28 degrees Celsius in midsummer. This can not only save electricity, but also prevent colds due to excessive temperature difference between indoor and outdoor. Take a 3-horse air conditioner at home as an example, its power is 2205 kW, and it is turned on 12 hours every day in summer, saving 2.205× 5 %×12 =1.323 kWh of electricity and electricity every month 16 yuan.
Household appliances are in standby state, and each household pays an extra 40-80 yuan electricity fee: the power consumption of electrical equipment in standby state is generally about 10% of its starting power, ranging from 5 watts to 15 watts. Every household has an electrical spare, and its energy consumption is equivalent to a 30-50 watt light bulb. If these appliances stand idly by for an average of 5- 10 hours every day, the annual standby power consumption will exceed 9 1- 180 kwh, saving about 40-80 yuan's electricity bill every year.
Saving 50 yuan by changing an energy-saving lamp for each household: Take a 5-watt high-quality energy-saving lamp as an example, the price is 20 yuan, the measured service life is 5000 hours, the electricity fee per kilowatt-hour is 0.403 yuan, the electricity fee for 5000 hours is used (16. 12 yuan), and the lamp purchase fee is 36. 1 yuan; Its lighting effect is equivalent to a 40-watt incandescent lamp (service life 1000 hours). If you use the same electricity price for 5,000 hours (5 lamps are needed, each lamp is 1 yuan), it will cost 80.6 yuan and 85.6 yuan to buy lamps with 5 yuan money. That is to say, every household will save about 50 yuan by replacing 40-watt incandescent lamps with 8-watt energy-saving lamps with the same brightness.
Master the trick of saving water and drive the whole family with one person.
Water resources are increasingly scarce, and water charges continue to rise, so that everyone has to pay more attention to water conservation. In addition to using new water-saving faucet and other products, there are some water-saving tips. This can not only save a sum of living expenses, but also respond to the call of the state to save energy, which can be described as killing two birds with one stone. Of course, water-saving appliances and methods are actually secondary, and the key is consciousness. If you really have a sense of saving water, you can naturally "open source and cut expenditure" and drive the whole family by one person.
Habitual article
The most important thing to save water is to change personal water habits. A good habit can help you save a lot of water. For example, many people often forget to turn off the tap when the water is not interrupted. I prefer to let the water flow when I wash my hands, face and brush my teeth, but I don't know that these habits waste a lot of water. According to analysis, a family can save about 70% of water as long as they pay attention to getting rid of bad habits and develop a good awareness of water saving.
It is also an important habit to regularly check whether toilets, pools, faucets or other water pipe joints, as well as walls or underground pipes are leaking. Because water leakage at home is a common occurrence and a great waste. A faucet can drop five or six liters of water a night, so if it leaks, it must be repaired immediately or simply replaced with a new water-saving product.
In fact, there are many similar good habits, such as putting a container under the faucet and accepting water for washing hands and fruits at any time; Don't use the toilet to flush cigarette butts and small garbage; Don't waste a lot of water for a glass of cold water. ...
Method article
There are many ways to save water. The following are some feasible and general methods for your reference.
Washing clothes and water can be reused.
Water saving efficiency: ★★★★★
Laundry is a big household water user. In order to save water, clothes should not be washed separately one by one. Small pieces and small batches of clothes advocate hand washing, which can save a lot of water. If it is too much trouble to wash one by one manually, you can accumulate more dirty clothes and throw them into the washing machine. Because, when the washing machine washes a small amount of clothes, the water level is set too high, and the clothes drift around in it, and there is no friction between them. On the contrary, it is not clean and wastes water. In addition, if the rinsing water is left as the washing water for the next batch of clothes, 30-40 liters of clean water can be saved at a time.
Take a bath, don't let the water run away in vain.
Water saving efficiency: ★★★★★
First of all, shower should be advocated in bathing, which is more water-saving than bath. If you like bathing very much, you can use a water-saving bathtub, because it is not only small in size but also uses circulating water. When choosing a shower, don't leave the water running all the time. You should choose a low-flow shower head and learn to adjust the ratio of hot and cold water. Secondly, try to get wet from head to toe, then wipe the whole body with soap and wash it again at last. If you must take a bath in the bathtub, be careful not to fill it with water. 1/3- 1/4 is enough. Many people in the family need to take a bath, but they can queue up one after another to take a bath, which can save the amount of cold water lost before the hot water flows out.
Toilet, reduce the amount of flushing
Water saving efficiency: ★★★★
If you think the water tank of the toilet is too big, you can put a brick or a bottle full of coke vertically in the water tank to reduce the amount of water you flush each time. You can also lower the fan-shaped support frame on the overflow pipe in the water tank to 20 mm away from the ball valve, that is, only allow the ball valve to rise to 20 mm or open a small hole on the rubber ball valve to control the water outlet of the water tank.
Multi-purpose, environment-friendly and water-saving method
Water saving efficiency: ★★★★
To put it bluntly, don't let the available water flow away in vain, let them be fully utilized. As mentioned above, the water for washing clothes is used for the next washing or flushing the toilet. You can also wash dishes and chopsticks with rice washing water and boiled noodles to remove oil and save water; Washing water such as vegetable washing water, washing water, dish washing water and car washing water for watering flowers and washing cars; The water from fish farming is used to water flowers (which can also promote the growth of flowers and trees); You can wash your feet with face wash water and then flush the toilet.
Water, the basic substance on the earth, deserves our praise! She gave birth to the world and all sentient beings; It is she who provides energy for life and makes life survive; Or did she let life develop continuously and become more and more prosperous? Therefore, it is no exaggeration to say that "water is the source of life".
But is water inexhaustible? We can definitely answer: No, although 70.8% of the earth is covered with water, 97.55% of the water is seawater, which can neither be directly drunk nor irrigated. Of the remaining 2.5% fresh water, the water that humans can really use is less than 1% of the global total fresh water. It is true that from the appearance of primitive life on earth to the present, water has been serving life, working hard and never stopping. But I don't know if you have thought that there is a limit to the endurance of water, and now water resources are in short supply! There are two main reasons for this situation: first, the lack of nature itself; Second, man-made destruction. Of course, we can't blame God for being unfair to us and giving us a planet short of water. On the contrary, we should thank God for creating a beautiful home for us.
However, it is in this emergency that we humans continue to waste and destroy water resources. Because a large amount of industrial wastewater is discharged into Lian and Rong rivers, the water quality of the two rivers is seriously polluted, and the water quality only reaches the third class standard, so it can neither be drunk nor used for irrigation. As an island county like South Australia, its water use depends entirely on "God's arrangement"-the rainwater collection area of all Shantang reservoirs, including flood diversion projects, only accounts for 3 1%, and it is still difficult for industrial and agricultural production and people's living water. It can be seen that it is urgent to properly handle the pollution and destruction of water resources. However, there is a serious shortage of water resources in the world today, and wars caused by water are increasing day by day. For example, of all the resources in the Middle East, water is the most likely to cause crisis, and water in the Middle East is more expensive than oil. Most countries in the Middle East are seriously short of water. The Middle East has suffered from drought for more than ten years and is facing a serious water crisis. The Little Jordan River has given birth to two major religions, which is the most hotly contested water source in the Middle East, and four wars in the Middle East have been related to this. The Jordan River provides two-thirds of the water for Lake Galilee, Israel's main water source. The Johnston agreement of 1955 stipulated the water quantity of all parties, but only Israel signed it, and Arab countries wanted to cut off the Jordan River in the 1960s. 1965, the Israeli army bombed the interception equipment in Syria. Both Arab countries and Israel take the destruction of competitive water resources as their primary strategic goal, and Israel has occupied the Golan Heights, the birthplace of the Jordan River. One of the difficulties in Syrian-Israeli negotiations is that Israel insists on occupying most of the water sources in the West Bank. At present, the water resources in Palestine are completely controlled by Israel, and the per capita water consumption is only three-quarters of that of Jewish settlers, but the cost is as high as twice. Pakistan had to over-extract groundwater, which made the water quality worse. The groundwater in Gaza has become too salty to be used. Since the violent conflict, Pakistan's water resources have been neglected, and the water shortage is more serious.
There is no comprehensive agreement on sharing water resources among the three major water systems in the Middle East, and disputes continue. The Nile flows through 10 countries, and the upper reaches are influenced by Egypt. Egypt built the Aswan Dam, which solved the water problem, but it caused dissatisfaction among upstream countries. Whenever there is a dispute, Sudan threatens to cut off water. Ethiopia signed an agreement with Sudan in 199 1 to extract 4 billion tons of river water every year. Egypt strongly opposes it. Turkey is rich in water resources, and the construction of South Water by Turkey to reduce the water flow to Syria and Iraq has been strongly opposed by both countries. Turkey and Israel have reached an agreement to transport the Manafort River to Israel by world ships, and Jordan and Syria are also considering buying water from the soil. Turkey hopes to play its role as a water power and promote cooperation and stability in the Middle East. Israel wants Turkey to increase its water supply to Syria. In exchange for Syria's concession to the border of Lake Gali, Turkey refused to get involved in the complicated Arab-Israeli dispute.
It can be seen that the shortage of water resources will be buffered for a period of time in order to use the right. It is not easy. The only way is to save water, and in this respect, Israel has done better. Two-thirds of Israel is desert, and there is no rain for seven months in a year. The per capita water resource is nearly 70 cubic meters, which is less than 1/4 in the Middle East, 3% in the world and 1/8 in China. However, it is in this barren and water-deficient land that Israel has built modern agriculture through scientific water use, which has amazed the world.
Agriculture is the foundation of Israel's founding. 1952, Israel spent 100 and 500 million dollars, and completed 10/45 km of "South-to-North Water Diversion Project". In the mid-1960s, the scientific water use method of drip irrigation was popularized, which promoted the rapid development of agricultural economy. The agricultural population in Israel has dropped from 60% to 3%, and a farmer can support 90 people, with a per capita GNP 1 80,000 USD, ranking first in the world 12. Israel cherishes water resources very much and regards water as its lifeline. Saving water is a systematic process, involving all aspects of society. Therefore, success has been achieved.
Water makes green grass greener.
Water makes flowers bloom.
Water makes trees tall and straight.
But you are getting haggard every day.
Aging every day.
Tears again and again.
If people do not cherish water resources, then the last drop of water in the world is people's tears.
