Water is the source of human life. Without water, human beings can't survive, everything can't grow, and the world won't be so colorful, so saving water has become a virtue all over the world. Below I have collected and sorted out "Composition on Water Saving" for you. Welcome to read for reference!
Composition on saving water 1
Water is the source of life. Without water, nothing can grow. However, with the development of the times, people waste more and more water resources. In order to save water, several sewage treatment plants have been built in the urban area to purify the sewage and reuse it. 20_ is the 26th "Urban Water Saving Week". This time, I was lucky enough to walk into Wu Nan Sewage Treatment Plant, a garden-like modern factory with reporter Qingying.
Wu Nan Sewage Treatment Plant is located in Xiacheng Road, Wujin High-tech Zone, covering an area of about 250 mu. It was officially put into operation in May, 2000, and was responsible for the collection and treatment of domestic and some industrial wastewater in six areas, including High-tech Zone, University Town, Nanxiashu, Lijia, Luoyang and Huang Qian. At present, the average daily sewage treatment capacity is 3. 20,000 tons, gathered to create a new model and concept of environmental protection and water control integrating sewage treatment, ecological wetland, urban landscape, reclaimed water reuse and popular science education. It is the second largest sewage treatment plant in Changzhou.
Walking into Wu Nan Sewage Treatment Plant, the green velvet grass here is dotted with wild flowers, butterflies are dancing, bridges are flowing, and sewage treatment equipment is hidden in dense trees. The beautiful scenery here is really like a beautiful landscape painting.
"How is the sewage treated?" "What is at work?" We scrambled to ask the uncle in charge of the crowd in the factory. Uncle Chao showed us around and explained that chemical technology and biotechnology are used in sewage treatment. The chemical process mainly includes stirring tank, sedimentation tank, oxidation tank and ultraviolet disinfection lamp. And biotechnology is used to treat animals, microorganisms, plants, etc. The water treated by chemical technology is reused by biology.
For further purification. This makes us admire again and again and gives us a world of life knowledge outside the textbook.
This visit is very short, but it made me understand that although there are sewage treatment plants, we still can't waste water resources. In our daily life, we can recycle water, and domestic sewage is filtered before being discharged ... Every bit of our daily life is water-saving, so we should start from ourselves and start from the side. Water saving and love the water are not far away.
Composition 2 on saving water
Water is the most precious thing that nature has given us. But we went to waste, and the Yangtze River and Yellow River were tossed and deformed. At this rate, the last drop of water will dry up sooner or later.
The water consumption per person per day is 0.0 15 tons. China people use about 0./kloc-0. 95 billion tons of water every day. There are 760 billion cubic acres of water in the Yangtze River, which can be drunk by the people of China for about 49,230 days. Although this is a long time for each of us, it is extremely short for the universe. And if we save a drop of water every day, we can save 65.438+300 million drops of water every day. What a big number this is!
It is easy to save a drop of water every day, or even more. For example, in winter, we can wash our feet with water. Flush the toilet with vegetable washing water; Water the flowers with the water that has been scoured; I also learned that the United States uses tons of plastic balls to cover the water in reservoirs to prevent the water from evaporating.
I noticed some bad habits of wasting water. The tap is on, but there is no water user. After washing your hands, the tap didn't turn off. I washed my face and took a big basin of water, but it poured out easily. Some people only wash a few clothes, but use several pots of water. These are shameful and wasteful behaviors.
A few days ago, my faucet broke down and it was leaking slowly. I connected it to the bottom with a bucket. When I saw it the next morning, I actually took a bucket full of water. Seeing this, dad quickly called the plumber. But the plumber has something to do and won't be here for a few days. We must put more barrels under it.
When the plumber came to repair it, we had received seven or eight barrels of water. From this matter. I know. We should save water.
Save water, start with me.
Composition 3 about saving water
People may also know that when the resources on the earth are about to be exhausted, most of them can find "substitutes" with human technology, but nothing can be replaced by water resources. Water is inexhaustible. The idea of "inexhaustible" should be corrected in our minds. According to some data, all the fresh water on the earth only accounts for about 2% of it. Excluding 1.7% glacier solid fresh water, the fresh water available for human development and utilization only accounts for 0.3% of the total water of the earth. In other words, water is scarcer and harder to find than air and sunlight.
How important water is to us! If everyone pays attention to saving water, I wonder how many people will benefit from it; On the contrary, if everyone wastes water resources carelessly, many people may suffer from drinking water difficulties! For example, some people have developed a bad habit, that is, they like to throw garbage into rivers and lakes or other inappropriate places at will for convenience. Imagine that if everyone throws garbage into rivers and lakes, a lot of water resources will be polluted; If everyone litters at will, when it rains, the rain will wash the garbage into rivers and lakes, thus polluting the water resources on which we depend. If a lot of water resources are polluted, how can we survive? I think this bad habit is a temporary convenience and a lifelong hazard, which must be eradicated!
We should learn some good methods from abroad, such as: carrying out "water resources education" to raise people's awareness of water saving, building pipelines to collect sewage from urban residents and public facilities, recycling urban sewage after secondary or tertiary treatment and purification, improving toilet washing equipment and adopting water-saving household equipment, so that we can save water better!
Let's 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!
Composition 4 Save water
Do you know that?/You know what? Now that the water is polluted, there is not much water to drink. China is actually a country short of water.
Please look at this scene: an old farmer slides a seven-or eight-year-old child into a deep well with a thick rope for a bucket or two of clean drinking water. If you don't want the last drop of water on the earth to be your own tears, please save water. Come and listen to my opinion:
1. Wash your face and hands. Don't turn on the tap too much. Turn on a small amount of water and turn it off in time.
Brush your teeth, run water continuously for 30 seconds, and then use 6 liters of water. Connect water with a cup, three glasses of water, only 0.6 liters of water. Three people twice a day, saving 486 liters of water a month.
Don't turn on the tap too big when cooking, it will waste water if you wash it for a long time. The flow rate of the faucet should be controlled, and the uninterrupted flushing should be changed to intermittent flushing.
4. Flush the toilet with foot washing water.
When washing dishes, wipe them with water before washing them, which can save water.
6. Don't let the water run for a long time in the shower, which will waste a lot of water. Don't drain too much water when using the basin, because whoever washes too much fruit will come out, which is a waste. When you use the bathtub, don't drain water at the same time, which will waste a lot of water. Everyone should put water in the shower intermittently, and turn off the water in time when scrubbing to avoid washing for a long time. After washing in the bathtub, the water can be used for washing clothes, washing cars, flushing toilets, mopping the floor and so on.
7. Wash the car, not with a hose. Although it only takes 20 minutes, it will take about 240 liters of water. Washing a car with bottled water requires only three barrels of water, using about 30 liters of water, saving about 2 10 liters of water. After listening to my advice, you will know to save water! If everyone saves a drop of water, it will save1300 million drops of water. If everyone wastes a drop of water, it will waste1300 million drops. Every little makes a mickle, save one drop a day, ten drops in ten days and a hundred drops in a hundred days. Then there will be no shortage of water.
Every little makes a mickle, and a drop of water can keep your life going.
Composition 5 about saving water
As we all know, with the rapid development of population, people's demand for water resources is getting less and less.
At present, China is one of the few countries lacking water in the world, but there are still many phenomena of wasting water around us. For example, in the bathroom, the tap is always on. After washing their hands, the students either forgot to turn off the tap, or the tap was not closed tightly, resulting in a lot of water flowing away in vain. How much green land can these wasted tap water irrigate? How many deserts can be turned into oases?
Today, the school launched a water-saving activity to let us know that there is no life without water. Groundwater is limited, not inexhaustible. So the students began to take action, especially when drinking pure water, which was not wasted at all. When they pour water, they always fill the bottle and accidentally spill it all over the floor. Since the launch of water-saving activities, students can drink as much as they can, and no one can waste water any more. Our class used to need three barrels of pure water a week, but now it needs two barrels a week.
Many of our classmates have come up with many good ways to save water. For example, rice washing water can be used to wash vegetables, fish farming water can be used to water flowers, and laundry water can be used to flush toilets and scrub floors. We also suggest that the headmaster's office replace the water tank that automatically flushes the toilet every five minutes in the school toilet with a hand-drawn water tank ... We not only put these ideas into practice, but also inspired everyone around us. Imagine if each of us saves a glass of water every day, then the water saved by people all over the world can be gathered into a running river … it will make our living environment better. "Don't let the last drop of water on the earth become human tears!" This statement is not alarmist. Saving is the traditional virtue of the Chinese nation. Let's act quickly to inherit this virtue!
