The first article: 600 words of three-level composition on protecting water resources.

On May 16, a reporter from Da Qiao Primary School visited Mengwan Algae-Water Separation Plant and Lucun Sewage Treatment Plant under the guidance of a teacher.

We first came to Mengwan algae-water separation plant. When we got there, everyone was talking, and some said, "What are those big pools for?" Some said, "How can the cyanobacteria in this water be separated?" The staff smiled and said, "Don't worry, you will know in a moment." We quickly followed the staff to the conference room. After we were seated, the staff began to introduce us. She said, "First, we pump the water containing cyanobacteria into the separation tank of the separation plant, and then bubbles will be generated in the water. With the increase of bubbles, cyanobacteria will float to the water surface, and then the machine will scrape off the cyanobacteria floating on the water surface and put the treated water back into Taihu Lake. " After listening to the introduction of the staff, I suddenly realized that it is no wonder that there are so many large pools in the factory, and each pool has different separation functions. The staff also told us: "The separated cyanobacteria are not waste. We can use it to generate electricity, make organic fertilizer and make fuel oil with low cost. " I think: It turns out that cyanobacteria can also be useful things.

Then, our team came to Lucun Sewage Treatment Plant. After we entered the treatment plant, an uncle showed us around. The first thing I saw was the coarse grid house, which intercepted the large pieces of domestic garbage in the sewage, and these garbage were loaded on trucks and transported to the garbage factory. Next, we came to the grid room, only to see the machine intercept the small particles and soft garbage in the sewage and transport them to the garbage treatment plant. At this time, I quickly asked: "What should I do next?" My uncle touched my head and said, "Don't worry, you continue to look down." I walked forward curiously and saw the high-pressure water pump, which is responsible for lifting the water to a height of 8 meters, and then the water will slide into various treatment tanks along the direction of gravity, such as microbial treatment tanks, so that microorganisms can remove toxic and harmful substances such as nitrogen and phosphorus. The second tank is responsible for the separation of microorganisms in the water, and then the water is transported out by the pneumatic water truck through the iron mesh filter tank and the filter cloth filter tank, and the preliminarily treated water is deeply cleaned.

This visit let me witness the superb sewage treatment technology with my own eyes, and also let us know the importance of protecting water sources and building a "sponge city". I want to work hard with you and strive to be a little environmental defender.

Chapter 2: Protecting Water Resources: 600 words for the third grade composition.

"Water is the source of life!" If there is no water, the earth will dry up; If there is no water, living things will perish; If there is no water, there will be no our beautiful world. We should cherish every drop of water and every tear of Mother Earth.

According to the data, the fresh water resources that can be directly used by human beings on the earth only account for 0.3% of the earth. Most parts of the earth are seriously short of water. Many trees, villages and fields are swallowed up by the desert, and the area of the desert is gradually expanding. The reduction of fresh water resources has seriously affected human economic construction and threatened human survival. Saving water and protecting water resources have attracted great attention of all mankind.

But how many people will save water resources? In our real life, around us, if you pay attention to observation, you will find that the waste of water resources is very amazing. Let's talk about our school first. We often find that there is no one near the faucet in public toilets, but the water in the faucet is dripping out, which will waste a lot of water. We have also seen that the faucet or water pipe in the school is broken and a lot of water flows out. Whenever I see this situation, I will run over and turn off the tap. If I can't turn it off, I'll tell the teacher to fix it in time.

In life, we often don't pay attention to saving water at home. For example, the water for washing vegetables and washing your face is poured into the sewer with a pot. In fact, the water can be reused. I saw my mother washing vegetables with this water. My mother said that the water for washing vegetables also has the function of sterilization and disinfection, and the water for washing vegetables is reserved for washing dishes. The water for washing clothes and washing face is used to flush the toilet. I used to brush my teeth and wash at the same time. When my father saw it, he severely criticized me, reasoned with me and tested it on the spot, letting me know how much water was wasted by brushing my teeth. Dad took a bucket and put it under the tap for two minutes. He said that this is the water that I have to waste at least once when brushing my teeth. I don't know. I don't know. I was really shocked when I saw it. Most of the clean water was inadvertently wasted by me and flowed into the sewer in vain. Since then, this bad habit has disappeared from me, and I know how to cherish and save water better.

There are not many fresh water resources in China. As the advertisement says, "The last drop of water in the world will be the tears of mankind". If we waste water resources, the river will dry up one day. "Without water, wood will wither, without water, wood will dry up." Please start from yourself and save water from now on!

The composition of protecting water resources in grade three is 600 words.

Danjiangkou Reservoir is the water intake of the Middle Route of South-to-North Water Transfer Project, and Zhushan County of Hubei Province is one of the core water sources of the Middle Route of South-to-North Water Transfer Project. Zhushan, located in the hinterland of Qinba Mountain, covers an area of 3,586 square kilometers, governs 17 townships, 254 administrative villages and has a population of 470,000. Bamboo forest landscape resources are very rich, with dozens of rivers. The blocked river in the county is a tributary of the Han River, which runs through Zhushan for more than 200 kilometers from south to north, with an average annual runoff of more than 7 billion cubic meters. It accounts for 20% of Danjiangkou inflow. The success or failure of South-to-North Water Transfer Project depends on water quality and ecological protection. As one of the core water source areas of the Middle Route of South-to-North Water Transfer Project, Zhushan faces the dual pressures of water quality protection and economic development. Therefore, the Zhushan County Party Committee and the government regard serving the South-to-North Water Transfer Project as the top priority of the people of the county, abide by the historical mission, and strive to create a "high-quality water source area for the South-to-North Water Transfer Project". In order to ensure the realization of the goal of sending clear water from one river to the North, Zhushan has shut down and rejected more than 60 polluting enterprises, launched "ecological tough battle" and "green action plan" with high standards, vigorously strengthened ecological construction, environmental protection, pollution control and soil and water conservation, and launched a comprehensive water quality defense war in the water source area, making the water source area of South-to-North Water Transfer Project well known. Under the leadership of the county party committee and government, people in Zhushan County have successively implemented environmental protection measures such as returning farmland to forests, planting trees, returning farmland to grassland, and relocating immigrants, which have made great contributions to this project.

After years of hard work, the environment of Zhushan has undergone earth-shaking changes. Less arable land, more forests; There is less yellow and more green; There is less waste of water and more people save water resources; There is less sewage, and the river becomes clear; With less waste gas, the sky turns blue; There are fewer people littering casually, and the streets are cleaner. Environmental protection has become everyone's knowledge, and water saving has become people's conscious action.

Although the middle route project of South-to-North Water Diversion Project has been officially opened, the South-to-North Water Diversion Project is not over yet, and neither is our labor enthusiasm. In the days to come, we people in Zhushan County will, as always, cooperate with the South-to-North Water Diversion Project and continue to contribute to the South-to-North Water Diversion Project, so that this project can be successfully completed and one river and clear water can stay in the North and Beijing forever.

Chapter IV: The composition of protecting water resources in grade three is 600 words.

Water is a valuable resource for us. We use water every day: cooking, washing vegetables, washing hands, washing faces, bathing, even vehicles, and almost all objects use water. With water, we have this beautiful life. In the past, the water in the river was crystal clear, and you could almost see small animals and algae at the bottom of the river. When fish of all sizes see that you want to catch them, they will run away at once, but the clear water helps us. Those fish want to escape to other places. When we see where they swim, we stand in front of them so that the fish can't escape.

Now, the water in the river suddenly turns black. People continue to build factories and society becomes modern. The discharged waste gas and sewage blacken rivers and water in other places. In some areas, the river stinks to death, so people should hold their noses when they walk by. The water in the river is polluted, and the pests will be happy. This river is full of thousands of mosquitoes and flies in Qian Qian. People use lunch boxes, plastic bags, residual branches and leaves, discarded umbrellas, broken balls, feces pulled by animals and countless rubbish. People can see sewage discharged from pipelines along the river bank everywhere. We should go swimming less in summer to avoid being hurt by sewage. The exhaust gas from the factory is black, which will also pollute the water body.

We should protect water resources. Water is the source of our life. Let's not litter everywhere. Society should protect water resources. We should throw the garbage in order and put the cans in the yellow trash can; Put the lunch box in the white trash can; Put daily necessities in the green trash can; Put the paper in the red trash can. We not only throw rubbish everywhere, but also form a good habit of saving water.

We usually don't play with water whenever we have time. Some schools have set up several special places to wash their hands, but some people turn on the tap very loudly and seal the drain, so that more and more water flows in the basin and precious water is wasted. At present, the water on the earth accounts for 70% of the whole earth. Don't think there is so much water. Not 70% water can be drunk, only 10% water can be drunk, and the rest can't be drunk. Even this poor water, human beings still don't cherish it. At present, some countries are competing for oil. If we humans continue to pollute water resources in this way, we may cause a tragic water war in the future. The whole world should cherish water resources and save water, so that human beings can have a colorful life.
