On Monday afternoon, our class teachers and students came to visit the Xinzhiyuan Sewage Treatment Plant. At this time, I really couldn't wait to see how the black sewage was treated before it turned into clean water. I walked into the sewage treatment plant with questions in my mind.

We lined up neatly, and under the leadership of the staff, I was stunned by the extremely smelly, dark and dirty water.

Next, we went to the "gauze" system. The "gauze" can separate large objects. The separated water enters the biochemical tank for "microbial" treatment. If there are still many microorganisms, send them to the dehydration machine room for dehydration. At this time, the sound of the water from the "biochemical tank" flowing into the "sedimentation tank" was deafening, but the smell of the water was still very strong. On the way to the "sedimentation tank", the water flowed down under my feet, which was frightening.

We soon came to the "sedimentation tank" and saw that there was clear water above and sludge below. This water finally flows into the "disinfection pool", undergoes ultraviolet disinfection, and then can be discharged to the outlet pool.

On the way back, I pondered: Water is an important substance for human survival, and every drop of water must be cherished. Although I can't stop too many things that damage the environment, I can start from myself, starting from the small things around me, and do my part to protect water resources.

Today, my father and I got up early because I wanted to participate in the little reporter activity today. Looking out the window at the beautiful wind and sunny weather, I felt very excited.

Our little reporter activity this time is to visit Zhuzhou Longquan Sewage Treatment Plant to understand how urban sewage is treated. After about twenty minutes' drive we arrived at our destination. When I walked to the entrance of Longquan Sewage Treatment Plant, I saw sixteen big characters on a tall building: "Realistic and innovative, harmonious development, green humanities, pollution control and water purification". It was very eye-catching. I couldn't wait to go in and find out.

Under the leadership of the teacher and Uncle Miao, we started today’s visit. Uncle Miao never forgot to remind us to "pay attention to safety" during the visit, because there are many machines and pools here, and it will be dangerous if we don't pay attention. Throughout the morning, we visited the water inlet, grit tank, biochemical tank, MBR tank, and ultraviolet disinfection tank of the sewage treatment plant. Each pool has a different function. Through Uncle Miao's explanation, I learned that this place can process about 200,000 tons of sewage every day. There are more than 30 staff members. The dirty and smelly sewage every day is processed by these pools. It becomes clean water and is then discharged into the Xiangjiang River from Jianning Port, thus ensuring the water quality of our mother river.

Through today’s visit, I learned that this is how urban sewage is treated. After multiple processes, sewage can also become our domestic water. This little reporter activity was very interesting and meaningful. I hope to participate again next time! Visiting the Sewage Treatment Plant Essay 3

This morning, our class carried out social practice activities and organized everyone to visit the sewage treatment plant.

Early in the morning, the students gathered at the school gate early, and we lined up to board the tourist bus bound for Xinxi Village, Tieshan Town. After everyone arrived, the vehicle slowly drove towards the suburbs. High-rise buildings flashed past the car window. After a while, we arrived at our destination.

As soon as the tourist bus drove into the sewage treatment plant, I was shocked by what I saw! There are neat houses with neatly trimmed lawns in front and back. ah! What a beautiful sewage treatment plant! I thought the sewage treatment plant was dirty! It's so far from what I imagined.

After getting off the bus, we lined up and the uncle from the factory took us to visit the sewage treatment plant.

While we were visiting, we listened attentively to our uncle's introduction: "Our factory is located in Xinxi Village, Tieshan Town, on the outskirts of the city. It has been 6.7 years since the factory was completed and put into operation. It can treat hundreds of tons of sewage every day." I was very surprised to hear the explanation.

Then my uncle took us to the machine room where they worked, where there were aeration grit tanks, sedimentation tanks and many machines. The fine grid fence and coarse grid fence inside are used to filter various debris and pretreat wastewater; the biological pool uses biological and chemical principles to treat wastewater and reduce various harmful substances in the wastewater; the second-layer pool The water has been processed and can be discharged directly into the Longjin River.

After the tour, we returned to the office building and looked at the relevant information about the sewage treatment plant posted on the first floor.

Ah! Uncles and aunts at the sewage treatment plant, you are the beauticians of the environment. With your hard-working hands, you have turned the sewage in our lives into clear rivers and created a beautiful environment for our lives. Thanks to your hard work, we Thank you!

Yesterday, the weather was cool and a trace of white clouds drifted across the sky. The Ou.com reporter and I drove to the sewage treatment plant in a happy mood.

First visit the sewage treatment exhibition hall. The walls of the hall are hung with information about water resources and propaganda about sewage treatment projects, which are lifelike. Today's lecturer is Master Tang, who vividly introduces the CAST reactor treatment device, which is a scaled-down model of a sewage treatment plant that can oxygenate water.

Next we entered the sewage treatment plant, and the first thing we saw was the coarse grille, which can clean more than 20MM of garbage. "Oh! So there's a lot of junk on the thick grille," I yelled. "Yes". Master Tang guided us to continue walking forward as he spoke. The stench was so bad that we had to cover our noses when we reached the pump pit. The pump pit is 11 meters deep and can use high-voltage current to lift water to the pump room. Then a fine grille is used to remove 2MM of garbage, and then the sewage enters the biochemical tank for oxygenation, sedimentation, and water discharge. Finally it is discharged into Oujiang River. The settled sludge is compressed and dried by machines and sent to Longwan Binhai for incineration and power generation.

How magical the sewage treatment plant is! The domestic water used by every household and the wastewater discharged from factories are collected through the urban pipe network, and the waste is turned into treasure after treatment. When I grow up, I will invent a more magical machine to better protect our environment. Visiting the Sewage Treatment Plant Essay 5

On Tuesday afternoon, the teacher took the young reporters from Class 6, Grade 3 to visit the Xiangxiang Sewage Treatment Plant. When we were about to arrive, the teacher asked us a question: The sewage must pass through What procedures can turn it into clean water? We came to the sewage treatment plant with curiosity. The environment here is beautiful and clean. Manager Zhou took us to the conference room and introduced us to some basic information about the factory: the sewage plant built with an investment of 120 million can produce 25,000 tons of sewage every day. The students were surprised by its factory capabilities.

The technician in the factory led us to visit the sewage treatment plant. He told us that the sewage first passes through the coarse grating and the new grating to remove impurities in the water, and then passes through the cyclone desanding tank to filter the sediment and flows out. The water will be clear, and then after ultraviolet disinfection, the water will be clean and can be safely discharged into the mother river.

In the past, there was a layer of garbage floating in the Lianshui River. The river water was filthy, and people had poor environmental awareness. The garbage was poured into the river. The sewage in the factory was not treated and was directly discharged into the river, seriously polluting the environment and seriously polluting the environment. Affect people's health. Since the establishment of the sewage treatment plant, the river water has become clear and there is no more garbage. The sewage from the factory comes to the sewage treatment plant and is purified before being discharged. The river is also a good place for people to swim in summer. This is all the result of the sewage treatment plant!

The visit is over, and I understand even more: if everyone has a good awareness of environmental protection, protects our environment, and protects our mother river, the world will be better! Visiting the Sewage Treatment Plant Essay 6

Today, our small press group went to visit the Chengbei Sewage Treatment Plant.

As soon as we arrived, a big machine was displayed in front of us.

My uncle told us that this huge machine is called Yingtai Mountain, which is used to clean up garbage in the water. In addition, I also found a strange place. In a room, there is a long machine that looks like a big comb, but it is much bigger than a comb. , and there is also troublesome garbage on it - plastic bags and so on. My uncle told me that it was used to clean up larger garbage. Then we arrived at the second stop - the whirlpool sand sink, which is a pool where sand sinks. Then we came to the third stop, called the hydrolysis and acidification tank. A corner of the tank was covered with duckweeds. My uncle said that these duckweeds can help us purify sewage. Later we passed aeration tanks, oxidation tanks, etc., and they all played different roles.

Finally we entered the complex building and watched the educational film inside. I was very surprised when I saw one small water droplet decomposed into more than a dozen small water droplets. .

After coming out of the sewage treatment plant, I was thinking that if people were not so selfish, produced less garbage, stopped discharging sewage indiscriminately, protected the environment around us, and returned us a beautiful nature. There is no need for sewage treatment anymore. Essay on Visiting the Sewage Treatment Plant 7

The sun is warm, the breeze is blowing, and the sky is cloudless. It is really a good day for traveling. I packed my bags, got on the "special car", and admired the wild scenery of the mountains all the way, forgetting everything else.

When we arrived at our destination - the Kaihua County Sewage Treatment Plant, we followed the teacher's lead and penetrated into the factory. We first watched the first step in sewage treatment - filtering garbage. That is to say, the sewage flowing from the urban area passes through a coarse grille to filter out some larger garbage, and then passes through a fine grille to filter out smaller garbage. The filtered garbage is much cleaner than the original sewage. I have to marvel at the wonder of this sewage plant.

Then, the technician uncle led us to the processing location of the second process - the sedimentation tank. The euphemistic name means that the impurities that cannot be filtered out by the coarse grid are separated from the water through precipitation. We saw four pools in one go, and the water in each pool exuded the slightest smell.

When I think that this water becomes dirty and smelly because we don’t pay attention to environmental protection and throw garbage into the river at will, I feel full of guilt. In the future, I must protect the ecological environment, not throw away garbage at will, and make my hometown clean and beautiful again.

Finally, we went to the water outlet and looked at large piles of clear water flowing into the river. My mood also improved. Today, I witnessed the whole process of turning sewage into clean water. The only drawback...maybe it is that the water is not drinkable! However, I believe that soon, sewage will not only become clean water, but also drinking water!

On the way home, the sun seemed to be getting brighter, and even the wild flowers on the roadside became more beautiful! Visiting the Sewage Treatment Plant Essay 8

A few days ago, we visited the Ningbo Shinan District Sewage Treatment Plant!

Entering the site, a smell hit our noses. We had to cover our noses with our hands. Needless to say, this is the entrance of sewage. This is the first level of sewage treatment, and here " What greets the "sewage" are thick grates, which are like guards, intercepting larger garbage (such as plastic bags, leaves, etc.) without mercy. Next, the water inlet pump will continuously suck in the sewage, and the sewage will be "transformed" obediently in the grit chamber!

The second stage of treatment is that the sewage enters the biological reaction tank. In the large circular pools, various microorganisms will treat the pollutants in the sewage as their meal. Although the sewage is still yellow, the water quality has been purified. Then the sewage will enter the secondary sedimentation tank, where they will "self-reflect" for about 13 hours. The small granular garbage will "consciously" settle down, and the sewage will slowly become cleaner.

The last level is ultraviolet disinfection. The instructor brought a small bucket of treated water up, "Wow, it's clean!" We all shouted in unison! The treated sewage can be discharged directly into the Fenghua River!

The machines here work 24 hours a day, so they must be tired too! So kids, we need to save water and reduce sewage to protect the environment! Visiting the Sewage Treatment Plant Essay 9

On Sunday, the weather was sunny and cloudless. Our ten-year team went to visit the Qingjiang Sewage Treatment Plant together.

We smelled a stink as soon as we entered the door. The first stop we saw was the Wei Pond. The bubbling water in the Wei Pond was smelly and unpleasant. The smell really made people want to vomit. We also saw a basin of water, which was caused by people throwing rubbish in the water, making the waterside very dirty and smelly. The second stop was called the Rough Grid Well, which contained a lot of garbage and bugs. At the third stop, we came to the fine grate well. The function of this station is very similar to the previous one. The coarse grate well filters out the larger garbage in the sewage, while the fine grate well filters out the smaller garbage. Filter out. The fourth station is the aerobic tank, which uses a manual hoist and a submersible mixer to transport the garbage out. Next is the secondary sedimentation tank. There is also sewage in the secondary sedimentation tank, but it is much cleaner than the water in the previous stations, but you can still see it. To a big pile of dirt. At the back is the chemical final settling tank, which cleans the treated sewage. Finally, there is the clear water tank, which discharges the treated sewage, garbage, and insects. After a series of sewage purification , the sewage becomes clean and clear.

Today, I visited the sewage treatment plant. Not only did I learn knowledge, but also let us know that there is only one earth. We must protect it and cherish it. Do not litter, do not create pollution, protect water sources, and protect water. environment. Visiting the Sewage Treatment Plant Essay 10

Last Sunday, our White Moon team went to the Central Park and Yueqing Bay to observe the water pollution situation. We went to the Central Park first. As soon as we entered the park gate, we saw a small river with many small fish in it. Suddenly, we saw a dead fish. The fish was covered in red clothes, floating on the river, half of its body exposed. Such a situation happened in such a beautiful park, and we were not in a good mood. Going further, we saw another big river. Next to the river was a sign with many sentences about protecting the environment written on it. Along the river, we observed the river water in the Central Park, took photos to record the water pollution in the river, and thought about why people did not protect the river water. In the second step, we arrived at Yueqing Bay and continued to observe. When we came to the embankment, we saw a wooden bridge. There was a lot of loose and soft soil behind the wooden bridge. Looking to the left, there was a large sea, and there was so much on the roadside. There are so many clams, some are buried in the soil, and some are piled up into a hill. I think these should be fished out from the sea! Suddenly, a large pile of garbage appeared in front of us. The garbage smelled so bad that we just wanted to avoid it, and we couldn't help but feel sorry for the sea.

After observing Central Park and Yueqing Bay, we discussed that most of the pollution comes from ourselves, so I really hope people can protect the environment. I hope the water in the future will be cleaner than now! Essay on visiting the sewage treatment plant 11

"If you don't cherish water, the last drop of water in the world will be human tears." After our sixth-grade teachers and students visited the Wujin City Sewage Treatment Plant, I was very impressed. This sentence is deeply touching.

The sewage treatment plant is located on Renmin East Road, Wujin High-tech Development Zone, with a service area of ??45 square kilometers and a service area of ??nearly 450,000 people. Centralized treatment of urban sewage in the area west of Cailing Port, east of Yancheng Road, north of Wunan River, south of Changzhou City, as well as Hutang Town, University Town and the West District of the High-tech Zone.

Let’s first go to the main control room of the sewage treatment plant. This is its “heart” and all monitoring of sewage treatment is here.

Here you can see the entire process of sewage treatment. Teacher Wu introduced: "This is a schematic diagram of the process of sewage treatment... The two computers in front monitor the operation of sewage treatment at all times..." With Teacher Wu's detailed explanation, I I have long wanted to see the most important part - the grit settling tank.

The grit chamber is used to precipitate larger inorganic particles and discharge them into anaerobic ditches. There is very little oxygen in the anaerobic ditch, which allows microbial cells to multiply rapidly and fight against microorganisms. While introducing, the teacher pointed to the large pieces of things floating on the pool and said to us, "Students, if you look carefully, you will find that there are turbid and small objects floating on the oxygen ditch. These are microorganisms and organic matter, phosphorus and nitrogen." The corpses left behind during the "struggle". Hearing this, the students were extremely surprised.

After the thrilling "struggle", the clean water flowed into the ultraviolet disinfection pool. After ultraviolet disinfection, the water reaches the discharge standard and can be discharged into Cailing Port. It is a magical process from sewage that can be used as ink to extremely clean water!

After this visit, I understood that we should produce as little domestic sewage as possible in our lives and contribute to protecting the home of the earth. Essay on Visiting Sewage Treatment Plant 12

There are many sewage on our earth. We, the young reporters from Class 252, went to the sewage treatment plant together.

The large group set off, laughing and chasing each other all the way. Some students were enjoying the scenery by the river, and some were enjoying the scenery by the river. While eating snacks, some students were competing and running... The male students were so excited that they really wanted to go there and play, regardless of the dewdrops falling drop by drop on their bodies.

A gust of breeze blew through. Thousands of green willows are blowing, and peach blossoms and cherry blossoms are smiling. This scene is like a painting! The birds in the sky are greeting us, and the sun is smiling at us.

When we got there, we couldn't help but cover our noses as soon as we entered the door. We knew how the sewage was discharged. We talked as we walked. When we saw the water in the pool opposite, I was surprised and said: Ah, how come the smelly water is there? How could it become such clear water? I was puzzled. There were countless small fishes swimming around in my mind. The water was so clear that it looked like the spray of two dragons. We passed by many sewage tourist areas. The most unforgettable thing for me is the single-plank bridge. There is clean and clear water under the single-plank bridge. As soon as we step on it, we will tremble nervously.

Looking forward to it, we finally came to the question-and-answer session. Everyone asked our uncle and aunt. Questions were really like little reporters chattering away. Time flies, we have to go back to school, and everyone left reluctantly.

Passing the sewage treatment plant. The visit made me understand that there is only one earth and we must take good care of it. Water resources are precious and we must save water. Essay on Visiting the Sewage Treatment Plant 13

One sunny day, the teacher. A group of lively and cute "little rabbits" are walking on the embankment of the park. Who are these rabbits? They are our classmates in Class 252!

We are taking us to the sewage treatment plant. We were talking and laughing along the way and saw a lot of garbage, so we picked up the garbage on the road and put it in the bags. In a blink of an eye, we arrived at the long-awaited sewage treatment plant. Ah, we looked around and saw many machines. Directly in front of us, there are green grass and red flowers all around. They are so beautiful! We went up the stairs, and there was a lot of sewage. Some of the sewage had oil floating on it, some of the water was filled with garbage, and some had a disgusting smell. We didn’t want to go forward. It was a huge machine. The machine makes the sewage keep rolling in the pool. What's going on? After listening to my uncle and aunt's explanation, I learned that this machine can increase oxygen, promote the growth of microorganisms, and allow the microorganisms to eat harmful bacteria in the water, so that there will be no bacteria in the sewage. Although there are no bacteria in the sewage, it is still smelly and dirty. Under the leadership of the teacher, we came to another machine. This time we were not looking at the machine, but at the garbage under the leakage net next to the machine. There were piles of garbage under the leakage net, as high as a mountain.

The clean water is like a big mirror, which is simply incomparable with the sewage. The water coming out of the two big holes is clean without any stains. This clean water will flow into the Lianshui River. The teacher took us to the drainage outlet. The white waves lapped the water and we hugged our mother's arms. When the time came, we had to leave, and we reluctantly left the sewage treatment plant.

Here, I call on everyone not to litter and to protect the environment. One earth is enough, one ocean is enough, but what is not enough is the environment. Visiting the Sewage Treatment Plant Essay 14

Today, Teacher Li organized us to visit the sewage treatment plant.

I was extremely happy to participate in group activities with my classmates. I talked and laughed with my classmates along the way. However, as soon as I arrived at the sewage treatment plant, I smelled an unpleasant smell and immediately wrinkled. He frowned.

The staff led us to visit and explained to us the whole process of sewage treatment.

The staff sister led us to the first step of sewage treatment-the intercepting well.

We saw piles of sludge-like things on the trolley, and a bad smell came to our faces. My sister told us that they were thrown into the river by people salvaged from the intercepting well. clothes, plastic bottles and other waste, my heart sank. Yes, we don’t pay attention in our daily lives and litter at will. This is really not the way to go. Later, my sister explained to us the specific functions of coarse grilles, fine grilles, oxidation ditches, secondary sedimentation tanks, etc...

The activity was over, but my heart could not be calm for a long time. This reminds me of the river next to our school. My father said that when he was a child, it was a clear river. They often played by the river, but now it has become a stinking ditch.

This is because not only industrial wastewater is discharged here, but also people living nearby throw domestic garbage and construction waste here for convenience. Our creek has become what it is today.

We say "I want to protect the environment" all day long, but it is useless to just talk without doing it. Let us take practical actions and start from the little things around us.

In order to keep the river clear, to make the sky bluer, and to give animals and plants a home to live in again, let us "contribute to environmental protection" together. Visiting the Sewage Treatment Plant Essay 15

Today, I came to the school early because today our school is going to visit the sewage treatment plant. Under the leadership of Teacher Wan, we came to the Liuwei Sewage Treatment Plant.

As soon as the bus drove into the sewage treatment plant, I was surprised by what I saw: neat houses with neatly trimmed lawns in front and behind. I thought the sewage treatment plant would be very messy and dirty, but I didn't expect it to be very different from what I imagined. After getting off the bus, we lined up and were taken around by uncles and aunts in the factory. We listened to their explanations and took notes.

First of all, we visited the water collection well. My uncle said that this water collection well is 10 meters deep! Then we came to the machine room of the magnetic levitation blower and learned that the blower is equivalent to a machine that delivers oxygen to microorganisms. There are many microorganisms in sewage. Finally, we came to the biological pond, secondary settling pond and water distribution well. The reason why the biological pool is called this is because there are many microorganisms in this pool. Its function is to use organisms to treat wastewater and reduce various harmful substances in the wastewater. After the secondary sedimentation tank, the purified water can be directly discharged into the Grand Canal.

After the visit, I want to say to the uncles and aunts at the sewage treatment plant: "You have worked hard! You are environmental beauticians. Without your hard work, the sewage in our lives would definitely not be able to be treated. Then The last drop of water in our world is our tears. ”
