有關SBR污水處理法的英文文獻
(中文):
SBR( Sequencing Batch Reactor Activated Sludge Process )是一種好氧微生物污水處理技術,是連續進水、間歇排水的周期循環間歇曝氣系統。該工藝集調節、初沉、曝氣、二沉、生物脫氮等過程於一池,按不同的時間順序進行各種目的不同的操作,全部過程都在一個池體內周而復始地進行,工藝流程簡潔,布局緊湊合理,是一種先進的污水處理系統。該技術適用於處理市政生活污水和中低濃度有機工業廢水,能有效地去除廢水中BOD5和懸浮固體(SS),將廢水中的氮化合物轉成硝酸鹽,進而轉成氨氣,使出水的氨氮(NH3-N)含量大大降低。與之相比較,傳統的連續流水處理系統CFS( Continuous Flow System )是在空間上設置不同的設施而在同一時間內進行各種操作。該工藝將調節、初沉、曝氣、二沉、生物脫氮等過程設於多個池內進行,限制了反應器的功能,擴大了使用空間和佔地面積,使運行速度遲緩,空間和地面的有效利用率降低,不適應於大中城市工業廢水、生活污水和其它多種復雜環境中各種廢水處理的需要。
(英文):
SBR (Sequencing Batch Reactor Activated Sludge Process) is one kind of good oxygen microorganism sewage treatment technology, is enters the water, the intermittent draining water cycle of motion intermittence aeration system continuously.This craft collection adjustment, initially sinks, the aeration, two sinks, processes and so on biological denitrogenation in one, carries on each kind of goal different operation according to the different time order, the complete process all again and again carries on in a cell body, the technical process is succinct, layout compact reasonable, is one kind of advanced sewage treatment system.This technology is suitable for the processing municipal administration sanitary sewage and the low concentration organic instrial waste, can remove in effectively the waste water BOD5 and suspended solid (SS), transfers the waste water in nitrogen compound the nitrate, then transfers the ammonia, causes the water leakage the ammonia nitrogen (NH3-N) content to rece greatly.Compares with it, traditional continuum water disposal system CFS (Continuous Flow System) is establishes the different facility in the space to carry on each kind of operation ring the same period of time.This craft will adjust, initially sinks, the aeration, two sinks, processes and so on biological denitrogenation supposes Yu Duoge in the pond to carry on, has limited the reactor function, expanded the use space and the area, caused the running rate to be slow, spatial and the ground effective use factor reced, did not adapt in the big or media-sized cities instrial waste, the sanitary sewage and other many kinds of complex environment each kind of waste water processing need.

水污染英語作文
pring is tht best season of the year. The weather gets warmer and warmer. My clas i'amates and I took a one-day sightseeing around our city.The scene was pretty. But when we saw the rivers along our city, I felt very sorry, and thoughit a lot.
With the development of modern agriculture and instry, more and more waste water is being poured into rivers. It has caused serious pollution. The river is becoming so dirty that no living things can live in it. The river is giving off a terrible smell.
We make an urgent appeal that measures should be taken to cope with the situation. Our government should start building various facilities such as sewage treatment!plant and encourage scientists to work out more and better ways to rece the pollution of water. Water is tho source of our lives. It is very important to protect water.
春天是一年中最好的季節，天氣變得越來越暖和。我和我的同學們進行了一次環城一日游，所到之處景色宜人。但當我看到沿著城區流過的河流時，我感到很惋惜，想了很多。 隨著現代工農業的發展，越來越多的污水排進河裡，河水被嚴重污染。河水變得如此的骯臟以致於生物不能在裡面生活。河水發出難聞的氣味。
我們急切呼籲採取措施改變這種狀況。政府應當建立各種設備，例如污水處理廠，並且鼓勵科學家們想出更多更好的辦法以減少水污染。 水是生命之源，保護水資源十分重要。
My classmates and I had an outing this spring. We had a good time. But meanwhile I noticed that water pollution in our city was becoming more and more serious.
On our way, we could see women washing clothes in the river. Litter was floating on the river. Waste water proced by a chemical factory was being discharged into the river. We did not see any fish in the river. The fiver was not so clear as before. Water quality was very bad. I am worried
about it because water is important to all living things. Man can not live without water. I hope people pay more attention to this problem, especially the government. Try to control the pollution of water as early as possible.
At last I would like to say, "To protect water is to protect life."
今年春天，我和我的同學去春遊，我們玩得都很高興。但同時，我也注意到我們城市的水污染變得越來越嚴重了。
沿途我們看到許多婦女在河邊洗衣，河面上漂著垃圾，一家化工廠正將廢水排入河中。河中看不到一條魚，河水也不像從前那樣清澈了，水質很差。對此我深感擔憂，因為水對於所有生物都非常重要。沒有水人類將無法生存。我希望人們能多關注這個問題，特別是政府部門，爭取及早解決水污染問題。
最後，我想說「保護水就是保護生命。」
The Importance of Water
hello,my name is cui xuerong,today I'm going to talk about the importance of water. Water is very important for living things. Without water there can be no life on earth. All animals and plants need water. Man also needs water.
Water is found atmosteverywhere. Even in the driest part of the world there is some water in the air.
As we all have found out, water may be a solid, or a liquid or a gas.When it isa solid, it may be as hard as brick, When itis a liquid, you can pour it out of a container. When it is a gas, you cannot see or feel it.
Although about 70 percent of the earth's surface is covered with water, But with the rapid development of agriculture and instry, more and more water is needed. Therefore, water is becoming scarce in many places. What's more, a lot of rivers and lakes are beginning polluted by the waste watcr from factories. Fish can't live in them any longer. At the same time, thc waste water does great harm to people's health.
In order to make rivers and lakes clean and prevent water from being polluted,we must do something to stop all sorts of pollution.

大家好，我是崔學榮，今天我要和大家談一談水的重要性。
水對生物很重要，沒有水，地球上就沒有生命。所有的動植物都需要水。人類也需要水。
水幾乎無處不在。即使在世界上最乾燥的地方，空氣中也有水。
水，正如你所了解的，有固態、液態和氣態。當它是固態時，它可以像磚一樣硬；當它是液態時，你可以將它從容器中倒出；當它是氣態時，你看不見或感覺不到它。
雖然地球表面70％是水覆蓋著，但是隨著工農業的迅速發展，水的需要量越來越大。因此，許多地方缺水。而且，許多河流湖泊被工廠排放的污水所污染，魚不能生存。同時，廢水給人們的健康帶來極大的危害。
為了保持河流湖泊清潔，防止水污染，我們必須採取措施，阻止各種污染
⑷ 關於海洋污染和如何保護的英語作文、
The simplest water pollution definition would be any contamination of water bodies with some pollutant(s) that changes physical, biological, and chemical conditions of any body of water making this water harmful for environment and surrounding ecosystems.
Water pollution occurs once too much pollutants (mostly in form of different waste) are discharged directly or indirectly into water bodies. Water pollution does not only cause great environmental damage but is also the leading worldwide cause of deaths and diseases responsible for the deaths of more than 14,000 people each day, mostly in developing countries.
Many people are not aware that water pollution is serious problem in almost all parts of the world, and not just in third world countries like some choose to believe. In fact many experts will tell you that reality is completely different than the common belief, and that actually water pollution problem is already out of control.
Water pollution problem is in most cases connected with the careless handling of chemical agents, toxins introced into our water through instrial mping, and farm runoff. All these factors make our water unsafe to drink.
For instance, the chlorine that is widely used to disinfect our water is believed by many to be carcinogenic, and therefore a major health issue that significantly contributed to worldwide rise of cancer rates.
Basically chlorine is present in every glass of water we draw from our tap, and although some studies have confirmed that chlorine can indeed be one of the cancer risk factors we simply cannot do without it because by removing chlorine from our water we would open the door to many waterborne diseases that would kill millions of people around the globe.
So how to protect yourself from water pollution? The best option available to us is to install a multi-layered home water filtering system in your home. The best option is multi media block system that has an activated granular carbon filter, a sub micron filter, and an ion exchange. This system is capable to prevent up to 99.99% of all of the harmful contaminants present in our water from entering your home.
High quality home water filtering system is really your best ally against water pollution.
