In the ordinary daily life, we all often come into contact with the essay, right, the essay must do to focus on the theme, around the same theme for in-depth elaboration, avoid East and West, the theme of lax or even no theme. Do you know how to write a good essay? The following is my visit to the sewage treatment plant essay, welcome to read, I hope you can enjoy.
Visiting the sewage treatment plant essay 1Monday afternoon, our class teachers and students came to visit the new source of sewage treatment plant. At this time I really can't wait to see how the black sewage actually processed to become clear water, I walked into the sewage treatment plant with questions in mind.
We lined up in a neat line, under the leadership of the staff, the strange odor, black and dirty water made me dumbfounded.
Then, we went to the "screen" system, "screen" can be separated from large objects, separated from the water into the biochemical pool, "microbial" treatment. If the microorganisms are still many, they will be sent to the dewatering machine room for dewatering. At this time, the water from the "biochemical tank" flows into the "sedimentation tank" when the sound is deafening, but the smell of water is still very big. On the way to the "sedimentation tank", the water under the feet of the water flowing straight down, it is frightening.
We soon came to the "sedimentation tank", see the top is clear water, the bottom is sludge. The water finally flowed into the "disinfection pool", ultraviolet disinfection, can be discharged to the water out of the pool out of the water.
On the way back, I pondered: water is an important material for human survival, we must cherish every drop of water. Although I can not stop the destruction of the environment too much, but I can start from me, from the small things around me to do, do their part to protect water resources.
A visit to the sewage treatment plant essay 2Today, my father and I got up early, because today I want to participate in the activities of small reporters. Looking out of the window wind and sunshine, my mood is very excited.
Our small reporter activity this time is to visit Zhuzhou Longquan sewage treatment plant, to understand how the city sewage is treated. About twenty minutes drive we arrived at the destination. Walking to the entrance of the Longquan sewage treatment plant, I saw a tall building sixteen big words "realistic and innovative, harmonious development, green humanities, pollution control and water purification" is very eye-catching, I can not wait to go in to find out.
In the teacher and Uncle Miao led us to start today's visit. Uncle Miao on the way to visit always remind us "must pay attention to safety", because there are a lot of machines and pools, if you are not careful will be dangerous. Throughout the morning, we visited the water inlet, sand sedimentation tank, biochemical tank, MBR tank and UV disinfection tank of the wastewater treatment plant. The role of each pool is different. Through Uncle Miao's explanation, I learned that this place can treat about 200,000 tons of sewage every day, and there are more than 30 staff members. Every day, the dirty and smelly sewage is turned into clean and clear water after being treated in these pools, and then discharged into the Xiangjiang River by the Jianning Port, which ensures the quality of the water of our mother river.
Through today's visit, I know that the original city sewage is treated in this way, after a number of procedures sewage can also be turned into our living water. This small reporter activity is very interesting, very meaningful, I hope the next time I can participate!

This morning, our class to carry out social practice activities, organized to visit the sewage treatment plant.
Early in the morning, the students early to concentrate on the school's gate, we lined up in a long line boarded the coach to the town of Tieshan Xinxi Village. Personnel arrived, the vehicle slowly drove to the outskirts of the countryside, a high-rise buildings from the car window passed by, in a short while, we came to the destination.
The tour bus drove into the sewage treatment plant, everything in front of me stunned! A neat house, in front of the house is neatly trimmed turf. 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, the uncle of the plant to take us to visit the sewage treatment plant. We visit, while listening attentively to the uncle said: "Our factory is located in the suburbs of the town of Tieshan Xinxi Village, the plant has been put into operation for 6. 7 years, can handle 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 work, there are aeration and sedimentation tanks, sedimentation tanks and many machines. Inside the fine grid fence and coarse grid fence is used to filter a variety of debris, pre-treatment of wastewater; biological pool is the use of biological and chemical principles of wastewater treatment, reduce the wastewater in a variety of harmful substances; two pools of water is processed, can be directly discharged into the Longjin River.
After the tour, we returned to the office building, watched the first floor posted information about the sewage treatment plant.
Ah! Sewage treatment plant uncles and aunts, you are the beautician of the environment, you use the hands of hard work, the sewage in our lives into a clear river, for our lives to create a beautiful environment, you have worked hard, we thank you!
Visiting the sewage treatment plant essay 4Yesterday, the weather was cool, a trace of white clouds drifting through the sky. I and ou net small reporter with a happy mood, drive to the sewage treatment plant.
First visit the sewage treatment exhibition hall, the walls of the hall are hung on the knowledge of water resources and sewage treatment project propaganda, image realistic. Today's lecturer is the Tang master, vividly introduced CAST reactor treatment device, is the sewage treatment plant is a scaled-down version of the model can give the water oxygenation.
Next, we entered the sewage treatment plant, the first to see the coarse grating, which can clean up more than 20MM garbage. "Oh! So there's a lot of trash on the coarse grate," I called out. "Yes." Master Tang said as he guided us onward. The stench along the way was so bad that we had to cover our noses to get to the pump pit. Pump pit 11 meters deep, can use high-voltage current, the water will be lifted to the pump room. And then carry on the fine grating to remove 2MM of garbage, after the sewage into the biochemical pool, oxygenation, sedimentation, water. Finally, it is discharged to Oujiang River. Precipitated sludge is compressed and dried by the machine, and sent to Longwan Binhai incineration power generation.
Sewage treatment plant is how amazing! The household water, factory wastewater discharged through the city pipe network convergence, after treatment of waste into treasure. When I grow up, I want to invent a more amazing machine, better protect our environment.
Visiting the sewage treatment plant essay 5Tuesday afternoon, the teacher took the third grade 6 class of small reporters to visit Xiangxiang City sewage treatment plant, almost to the time when the teacher gave us a question: sewage to go through what procedures in order to turn into clear water? We came to the wastewater treatment plant with a curious mood, the environment here is beautiful and clean. Zhou manager brought us to the meeting room, he introduced us to some of the plant's basic situation: the investment of 120 million built sewage plant, the daily sewage can be plant 25,000 tons. The students were amazed at the capacity of the plant.
The plant's technician led us to visit the sewage treatment plant, he told us that the sewage first through the coarse grating, new grating to remove impurities in the water, and then through the cyclone desanding tank filter sediment, flow out of the water on the clear, and then through the ultraviolet ray disinfection, so that the water will be clean, you can rest assured that the discharge of the Mother River.
In the past, the Lianshui River was floating with a layer of garbage, the river was dirty, people's environmental awareness is poor, the garbage is dumped into the river, the sewage from factories is not processed, and discharged directly into the river, which seriously polluted the environment and seriously affected people's health. Since the sewage treatment plant, the river water is clear, no longer see the garbage, the sewage from the factory to the sewage treatment plant, purified and then discharged. In summer, the river is a good place for people to swim. This is all the credit of the sewage treatment plant ah!
The tour is over, more let me understand: if everyone has a good sense of environmental protection, protect our environment, protect our mother river, the world will be better!
Visit to the sewage treatment plant essay 6
Today, our small press group went to visit the sewage treatment plant in the north of the city.
Just when we got there, a big machine was shown in front of us. Uncle told us that this huge machine is called Yingtai Mountain, is used to clean up the garbage in the water, and I also found a strange place, in a room there is a long like a big comb machine, but much bigger than a comb, and on top of it there are headaches of garbage - plastic bags and so on. My uncle told me that it was used to clean up the bigger garbage. Then we went to the second station - the Cyclone Sedimentation Pool, which is a pool where the sand sinks. Then we came to the third station, called hydrolysis acidification pool, in one corner of the pool is full of duckweed, uncle said, these duckweed can help us play a role in purifying sewage. Later we passed through the aeration pool, oxidation pool, etc., they also play a different role.
Finally, we went into the complex, and watched the missionary film inside, especially when I saw the decomposition of a small water droplet into a dozen small water droplets, I feel very surprised.
From the sewage treatment plant, I was thinking that if people are not so selfish, less garbage, do not discharge sewage, protect our surrounding environment, but also a beautiful nature. There would be no need for sewage treatment.
A visit to the sewage treatment plant essay 7The warm sun and warm, the breeze, the sky cloudless, really a good day for traveling. Pack your bags, sit on the "special car", all the way to enjoy the wild scenery of the mountains, has been put other things behind you.
To the destination - Kaifa County Wastewater Treatment Plant, followed the teacher's pace, hit the plant inside. We first watched the first process of sewage treatment - filtering waste. That is, the sewage flowing from the city, through a coarse grille, some of the larger garbage filtered out, and then through a fine grille, the smaller garbage filtered out. The filtered garbage is much cleaner than the original sewage, and I had to marvel at the wonders of this sewage plant.
Then, the technician uncle led us to the second process of treatment location - sedimentation tank. The beauty of the name is that the impurities that can not be filtered out of the coarse grille, after precipitation, and water detachment. We a **** saw four pools, each pool of water emitted a slight odor.
I thought of these waters because we usually do not pay attention to environmental protection, randomly dispose of garbage to the river to become dirty and stinky, my heart is full of guilt. In the future, I must protect the ecological environment, do not throw away garbage, so that the hometown, become clean and beautiful again.
Finally, we went to the outlet, looking at the big piles of clear water flowing into the river, my mood also changed for the better. Today, I witnessed the whole process of turning sewage into clear water, and the only shortcoming `...... may be that this water is undrinkable! However, I believe that soon, sewage can not only become clear water, but also into drinking water!
On the way home, the sun seems to be brighter, and even the wildflowers on the roadside look better!
Visiting the Wastewater Treatment Plant Essay 8
A few days ago, we visited the South District Wastewater Treatment Plant in Ningbo!
Into the scene, a stench coming from the nose, we can not help but use their hands to cover their noses, needless to say that this is the entrance to the sewage, which is the first barrier to sewage treatment, and here to "meet" the sewage is a coarse Geshan, they are like a guard, will be larger garbage (such as plastic bags, leaves, etc.) iron face to stop the garbage, and the sewage is not a good idea, it is a good idea. (such as plastic bags, leaves, etc.) Ironically retained down. Next into the pump to sewage constantly sucked into the sewage will be in the sand sedimentation tank obediently accept the "transformation" Oh!
The second stage of treatment is the sewage into the biological reaction tank. In a large circular pool, a variety of microorganisms will sewage pollutants as their meal, the sewage is still yellow, but the water quality has been purified. Then the sewage will enter the second sedimentation tank, where they will be "self-reflection" for about 13 hours, oh, particulate waste will be "consciously" precipitated, the sewage is slowly becoming clean.
The last level is ultraviolet disinfection, the narrator uncle played a small bucket of treated water to come, "Wow, clean! We 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! So kids, we need to save water, reduce sewage is also to protect the environment!
Visit to the sewage treatment plant essay 9Sunday, the weather is sunny, cloudless, we ten years of light team together to visit the Qingjiang sewage treatment plant.
As soon as we entered the door, we smelled a stench, the first station we saw the anaerobic pool, anaerobic pool of water bubbling with bubbles with stink and smell, the smell really makes people want to vomit. We also saw a basin of water, because people throw garbage in the water, making the water very dirty and stink. The second stop was called the coarse grating well, which had a lot of garbage and little bugs in it. The third station we came to the fine grating well, the role of this station is very similar to the previous station, the coarse grating well is to filter out the sewage in the slightly larger garbage, fine grating well is to filter out the small bit of garbage. The fourth station is the aerobic tank, it is a manual hoist and submersible mixer to transport the garbage out, followed by the second sinking tank, the second sinking tank also has sewage, but the water is much cleaner than the previous stations, but you can still see a large pile of soil. Behind is the dosing final sedimentation tank, it is to add drugs to the sewage side of the clean, and finally the clear pool, the clear pool is to add drugs to the sewage, garbage, and bugs discharged after a series of sewage purification, sewage will become clean, clear.
Today, I visited the sewage treatment plant, not only learned the knowledge also let us know, the earth is only one we have to protect it, love it, do not throw garbage, do not create pollution, care for water, protect the environment.
Visiting the sewage treatment plant essay 10Last Sunday, we white moon team went to the center of the park and Yueqing Bay together to observe the water pollution. We first went to the center of the park, a park door, see there is a small river, there are many small fish in the river, suddenly, we saw a dead fish. The fish was covered with a red dress, floating on the river, half of its body was exposed. Such a beautiful park had this situation, and we were not in a good mood. Walking further, we saw another big river, beside the big river stood a sign, on the sign was written many sentences to protect the environment. Along the river, we observed the river in the center park all over again and took photos to record the water pollution situation in the river, thinking about why people are not protecting the river. The second step, we went to Yueqing Bay, continue to observe, we came to the embankment, we saw a wooden bridge, behind the wooden bridge there are a lot of loose and soft soil, looking to the left, there is a large sea, there are more than enough clams on the roadside, some clams are buried in the soil, and others piled up into a small mountain, I think, all these should be fished out from the sea! Suddenly, a large pile of garbage appeared in front of us, the pile of garbage smelled very bad, stinking just want to avoid it, the heart can not help but for the sea heartache.
After observing the Center Park and Yueqing Bay, we discussed that most of this pollution comes from ourselves, so I really hope that people can protect the environment, and I hope that the water will be cleaner than now!
Visiting the Wastewater Treatment Plant Essay 11"If water is not cherished, the last drop of water in the world will be human tears." After our sixth grade teachers and students visited the Wujin urban sewage treatment plant together, I was y touched by this sentence.
The sewage treatment plant is located in the Wujin Hi-Tech Development Zone, People's East Road, the service area of forty-five square kilometers, service area of nearly 450,000 people. Centralized treatment of Changzhou City, west of Cailing Harbor, east of Drowning City Road, north of the Wunan River, Changzhou City, south of the region as well as the town of Hutang, the University City and the western part of the high-tech zone of the city's sewage.
We first went to the general control room of the sewage treatment plant, which is its "heart", all the monitoring of sewage treatment are here. Here you can see the entire process of sewage treatment, Mr. Wu said: "This is the flow of sewage treatment schematic ...... front of the two computers are always monitoring the operation of sewage treatment ...... "Accompanied by Mr. Wu's detailed explanation, I have long wanted to witness the most important link - sand sedimentation tank.
The sedimentation tank is where the larger inorganic particles settle and are discharged into an anaerobic ditch. The anaerobic tanks have very little oxygen, which allows the microbial cells to multiply quickly and fight the microbes. Teacher introduced while pointing to those floating in the pool of large chunks of things, said to us "students, look carefully you will find the oxygen ditch on the floating turbid small objects, which is microorganisms and organic matter, phosphorus and nitrogen "struggle" in the process of the bodies left behind. The students were surprised to hear this.
After a thrilling "fight", clean water into the ultraviolet disinfection pool. And then after ultraviolet disinfection, the water becomes to meet the discharge standards, can be discharged into the Cailin Harbor. From the sewage can be used as ink to extremely clean water, this is really a magical process!
After this visit, I realized that we need to produce as little sewage as possible in our lives to contribute to the protection of the Earth's home.

A sunny day, the teacher walked with a group of lively and lovely "bunnies" in the park on the embankment, this group of rabbits who is it? It is our 252 classmates! The teacher is taking us to the sewage treatment plant.
We laughed and joked along the way and saw a lot of garbage, so we picked up the garbage on the way with our garbage bags and put it in the bag. In a flash we arrived at the long-awaited sewage treatment plant. Ah, as far as the eye could see many machines were right in front of us, surrounded by green grass and red flowers, one big one big one, it was so beautiful! We went up the stairs, ah, a lot of sewage, some of the sewage floating oil, some of the bottom of the water is full of garbage, there is a sickening and unpleasant odor, we do not want to go forward, is a huge machine, so that the sewage in the pool kept rolling, what is going on? After listening to the explanation of the uncle and aunt, I realized that this machine can increase oxygen, promote the growth of microorganisms, so that the microorganisms will eat the harmful bacteria in the water, so that there is no bacteria in the sewage. Although there is no more bacteria in the sewage, it is still smelly and dirty. Under the teacher's guidance, we came to another machine, this time not to see the machine, but to see the garbage under the leaky net next to the machine, under the leaky net, the garbage was piled up, piled up as high as a mountain. The clean water was like a big mirror, no match for the sewage. From the two big mouths out of the water is clean, no stains, these clean water will flow into the Lianshui River, the teacher took us to the drainage port, the white waves lapping at the water surface, embraced into the mother's arms. Time is up, we have to go, still reluctant to leave the sewage treatment plant.

A visit to the sewage treatment plant essay 14Today, Mr. Li organized us to visit the sewage treatment plant.
With my classmates to participate in collective activities, my heart is incredibly happy, all the way to talk and laugh with my classmates, but as soon as we arrived at the sewage treatment plant, I smelled a bad smell, and immediately frowned.
The staff led us on a tour and explained the whole process of sewage treatment.
Sister Worker led us to the first process of sewage treatment - the interceptor well.
We saw a pile of sludge-like things on the trolley, a share of the unpleasant odor coming, sister told us that is the interceptor well salvaged people threw into the river clothes, plastic bottles and other waste, I heart not only a sinking, yes, we usually live without paying attention to the random littering, really should not. Later, my sister explained to us the specific role of the coarse grating, fine grating, oxidation ditch, two sedimentation tanks and so on ......
The activity is over, but my heart can not be calm for a long time. This can not help but let me think of our school next to the river, Dad said he was a child this is a clear river, they often play in the river, but now it has become a stinky stinky ditch.
This is because not only industrial wastewater is discharged here, even people living in the vicinity of the river for the convenience of domestic garbage, construction waste is also thrown into the river, our little river has become today's appearance.
We say all day long, "I want to protect the environment", but just say no is useless, let us take practical action, from the little things around us to do.
In order to let the river continue to clear, in order to make the sky more blue, in order to let the animals and plants to have a living home, let us together "for the environment, dedication".
Visiting the sewage treatment plant essay 15Today, I came to school early, because today our school is going to visit the sewage treatment plant, we are under the leadership of Mr. Wan, came to the six Wei sewage treatment plant.
As soon as the bus drove into the sewage plant, everything in front of me surprised me: a neat house, in front of the house is a neatly trimmed lawn. I thought the sewage plant will be very messy, very dirty, I did not realize that this is too different from what I thought. After getting off the bus, we lined up, by the plant's uncle and aunt to take us to visit, we listen to the uncle and aunt's explanation, while taking notes.
First of all, we visited the water collection well, listening to the uncle said, this water collection well has 10 meters deep it! Then we came to the machine room of the magnetic levitation blower, and learned that the blower is the equivalent of microorganisms to deliver oxygen to the machine. There are many microorganisms in the sewage. Finally, we came to the biological tank, the secondary sedimentation tank and the distribution well. The biological pool is called so because there are many microorganisms in this pool, and its function is to utilize the organisms to treat the wastewater and reduce various harmful substances in the wastewater. After the action of the second sedimentation tank, the purified water can be directly discharged into the Grand Canal.
At the end of the visit, I want to say to the uncle and aunt of the sewage treatment plant: "You work hard! You are the environmental beautician, if not for your hard work, we live in the sewage certainly can not be dealt with, then the last drop of water in our world is our tears. Thank you!"
