E. 有关污水排放建议的英语作文带翻译
处理污水，造福人类
Sewage, the benefit of mankind
随着科学技术的进步，几乎每个城市都有许多的工厂，工厂里每天排出的污水都污染了许多江河、湖泊，导致大部分的鱼虾中毒死亡；同时也威胁这自然界里的生物和人类的安危，对人类的生活造成了极大的影响。
With the progress of science and technology, almost every city has many factories, factory every day discharge sewage pollution of many rivers, lakes, cause most of the deaths of fish and shrimp; Also threaten the creatures of the nature and the human safety, caused great impact on human life.
我时常幻想着，假如这些污水经过处理，变成干净的、能饮用的水，那该多好啊！于是我就想到了需要一种能随意变大变小的“污水处理仪器”，我把它简称为“处污器”。它可以放在家里、学校里、也可以安装在工厂里。这个“处污器”是个正方形，外壳是一种踩不烂压不扁的塑料；它的心脏是由一块伸缩自如且永久使用的过滤网，一个具有除臭功能且永不变形的旋转筒和一片微型的智能电动芯片组成。这个“处污器”的电是用之不竭的，只要有一丝光亮，它就立刻把光能转化为电能，非常环保。这个“处污器”可以自动计算需要排出的污水量，然后根据排污量来改变自己的大小。比如：一间造纸厂每天生产一吨纸，只要你轻轻按红色按钮，它就自动计算出这间工厂的排污量，根据排污量把自己变大。再轻轻一按绿色按钮，“处污器”马上开始工作。污水流经入口的过滤网，所有的大大小小的垃圾就会被过滤掉。没有垃圾的污水直接流入旋转筒，旋转筒不停地转动去除臭味，再净化。同时，它会加入人体所需要的矿物质和微量元素，然后再通过出口排出来。这些经过处理的水非常神奇，人们喝了既可以美容又可以强身健体，少生病。动物喝了会更肥壮，再凶猛的动物喝了也会变得善良可爱。这些水用来浇灌禾苗，稻谷的产量会更高。这个“处污器”放在家里的时候，它会自动变小。家里的生活用水经过“处污器”可以循环利用。这样，我们不但达到了节约用水的目的，还保护了地球的生态环境。想到这里，我仿佛就生活在一个绿树成荫、鸟语花香、物产丰富、山清水秀……没有一丝污染的国家里。

The "basin" electricity is unlimited, as long as there is light, it immediately to convert light energy into electrical energy, environmental protection very much. The "basin" can automatically calculate need amount of sewage discharge, and then according to the size of the emissions to change itself. For example: a paper mill procing one ton of paper a day, as long as you gently press the red button, it will automatically calculate the emissions from the factory, according to position themselves. Gently press the green button again, "basin" start work immediately. The filter on the sewage through the entrance, all the big and small garbage will be filtered out. No garbage sewage directly into the rotating drum, rotating cylinder kept turning to remove odor, purify again. At the same time, it will join the minerals and trace elements of human need, and then discharged through exports. The treated water is very magical, people drink can not only beauty but it can strengthen physical health, sick less often. Animals drink will be more fat, and then drank the ferocious animals will become kind and lovely. The water used to irrigate the movie, the output of rice is higher. The "basin" at home, it will automatically become smaller. Home after "basin" of domestic water can be recycled. In this way, we not only achieved the purpose of saving water, protect the ecological environment of the earth. Thought of here, I like to live in a tree-lined, charactizing a fine spring day, rich natural resources, beautiful scenery... No any pollution in a country.
想到这里，我惊醒了，我想：这绝不是幻想的，这是我的梦想、理想。同学们，让我们行动起来，一起努力，保护环境，节约用水，珍惜水资源，处理污水，造福人类，为现实吧！
Thought of here, I woke with a start, I thought: this is not fantasy, this is my dream and ideal. Boys and girls, let's action, and work together to protect the environment, save water, cherish water, sewage, and for the benefit of humanity, for real!

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.
翻译：
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
G. 关于污水处理过程的英语作文
Title: Process in Recycle of Used Water.
A huge amount of used water are proced in our daily life. Treatment of used water not only prevents environmental pollution also saves water resource. Recyle of used water is usually involved in the following process. First, used water is introced into a sewage plant where the water are left steady for certain time. Precipitates are separated and used for fertilizers. The remaining water can be regarded as ordinary water which either is discharged into river or introced into a purification plant for fresh water.
Therefore, we must save water in our daily life!

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):
