⑵ 我急需一篇关于污水处理的英文文章要带译文 希望大家帮帮忙
有关SBR污水处理法的英文文献
(中文):
SBR( Sequencing Batch Reactor Activated Sludge Process )是一种好氧微生物污水处理技术,是连续进水、间歇排水的周期循环间歇曝气系统。该工艺集调节、初沉、曝气、二沉、生物脱氮等过程于一池,按不同的时间顺序进行各种目的不同的操作,全部过程都在一个池体内周而复始地进行,工艺流程简洁,布局紧凑合理,是一种先进的污水处理系统。该技术适用于处理市政生活污水和中低浓度有机工业废水,能有效地去除废水中BOD5和悬浮固体(SS),将废水中的氮化合物转成硝酸盐,进而转成氨气,使出水的氨氮(NH3-N)含量大大降低。与之相比较,传统的连续流水处理系统CFS( Continuous Flow System )是在空间上设置不同的设施而在同一时间内进行各种操作。该工艺将调节、初沉、曝气、二沉、生物脱氮等过程设于多个池内进行,限制了反应器的功能,扩大了使用空间和占地面积,使运行速度迟缓,空间和地面的有效利用率降低,不适应于大中城市工业废水、生活污水和其它多种复杂环境中各种废水处理的需要。
(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.

水污染英语作文
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节，天气变得越来越暖和。我和我的同学们进行了一次环城一日游，所到之处景色宜人。但当我看到沿着城区流过的河流时，我感到很惋惜，想了很多。 随着现代工农业的发展，越来越多的污水排进河里，河水被严重污染。河水变得如此的肮脏以致于生物不能在里面生活。河水发出难闻的气味。
我们急切呼吁采取措施改变这种状况。政府应当建立各种设备，例如污水处理厂，并且鼓励科学家们想出更多更好的办法以减少水污染。 水是生命之源，保护水资源十分重要。
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，我和我的同学去春游，我们玩得都很高兴。但同时，我也注意到我们城市的水污染变得越来越严重了。
沿途我们看到许多妇女在河边洗衣，河面上漂着垃圾，一家化工厂正将废水排入河中。河中看不到一条鱼，河水也不像从前那样清澈了，水质很差。对此我深感担忧，因为水对于所有生物都非常重要。没有水人类将无法生存。我希望人们能多关注这个问题，特别是政府部门，争取及早解决水污染问题。
最后，我想说“保护水就是保护生命。”
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，我是崔学荣，今天我要和大家谈一谈水的重要性。
水对生物很重要，没有水，地球上就没有生命。所有的动植物都需要水。人类也需要水。
水几乎无处不在。即使在世界上最干燥的地方，空气中也有水。
水，正如你所了解的，有固态、液态和气态。当它是固态时，它可以像砖一样硬；当它是液态时，你可以将它从容器中倒出；当它是气态时，你看不见或感觉不到它。
虽然地球表面70％是水覆盖着，但是随着工农业的迅速发展，水的需要量越来越大。因此，许多地方缺水。而且，许多河流湖泊被工厂排放的污水所污染，鱼不能生存。同时，废水给人们的健康带来极大的危害。
为了保持河流湖泊清洁，防止水污染，我们必须采取措施，阻止各种污染
⑷ 关于海洋污染和如何保护的英语作文、
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.
