『壹』 求一篇关于废水处理的英文文章
Raw Influent (Sewage) is the liquid waste from toilets, baths, showers, kitchens, sinks etc. Household waste that is disposed of via sewers. In many areas sewage also includes some liquid waste from instry and commerce. In the UK, the waste from toilets is termed foul waste, the waste from items such as basins, baths, kitchens is termed sullage water, and the instrial and commercial waste is termed trade waste.
The division of household water drains into greywater and blackwater is becoming more common in the developed world, with greywater being permitted to be used for watering plants or recycled for flushing toilets. A lot of sewage also includes some surface water from roofs or hard-standing areas. Municipal wastewater therefore includes residential, commercial, and instrial liquid waste discharges, and may include stormwater runoff. Sewage systems capable of handling stormwater are known as combined systems. Such systems are usually avoided since they complicate and thereby rece the efficiency of sewage treatment plants owing to their seasonality. In addition, heavy storms may overwhelm the sewage treatment system, causing a spill or overflow. It is preferable to have a separate storm drain system for stormwater.
The construction of combined sewers is a less common practice in the United States and Canada than in the past and is no longer accepted within building regulations in the UK and other European countries. Instead, liquid waste and stormwater are collected and conveyed in separate sewer systems, referred to as sanitary sewers and storm sewers in the U.S. and as foul sewers and surface water sewers in the UK. Overflows from foul sewers designed to relieve pressure from heavy rainfall are termed storm sewers or combined sewer overflows.
As rainfall runs over the surface of roofs and the ground, it may pick up various contaminants including soil particles, (sediment), heavy metals, organic compounds, animal waste, and oil and grease. Some jurisdictions require stormwater to receive some level of treatment before being discharged directly into waterways. Examples of treatment processes used for stormwater include sedimentation basins, wetlands, and vortex separators (to remove coarse solids).
The site where the process is concted is called a sewage treatment plant. The flow scheme of a sewage treatment plant is generally the same for all countries:
Mechanical treatment;
Influx (Influent)
Removal of large objects
Removal of sand and grit
Pre-precipitation
Biological treatment;
Oxidation bed (oxidizing bed) or aeration system
Post precipitation
Effluent
Chemical treatment (this step is usually combined with settling and other processes to remove solids, such as filtration. The combination is referred to in the US as physical-chemical treatment.).

『伍』 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。
I often fantasize about, if the wastewater has been treated, can become clean, drinking water, that it would be good! So I was thinking about can need a casual becomes big small "sewage treatment instrument", I put it referred to as the "basin". It can be put in the home, school, also can be installed in the factory. The "basin" is a square, the shell is a kind of trample bad pressure not flat plastic; Its heart is a piece of retractile and permanent use of filter, a deodorization function and never deformation and the rotating drum and a chip of the intelligent electric chip. 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!

现在,因为我长大了,正在变成大人,所以在家长眼中,我已不再是小孩了,已变得有意识,有胆量,有知识了.有时,他们东一句“你已经长大了!”西一句“你不再是小孩了!” 听得我头都疼了.现在的我无论做什么事,自己都要先认好“罗盘针”,都必须要有原则在身,不能马虎完成,也不能粗心对待,如果稍有差池,随时都会招来暴风雪.

『拾』 五水共治英语作文还能做什么
五水共治是指治污水、防洪水、排涝水、保供水、抓节水，这的确是五个要非常重视的的问题，可为什么会在江南水乡出现这个问题呢？原来，现在有好多工厂都把废水和赃物排放到河里，造成很多河流严重污染水质；所以，才会出现“五水共治”。
我在书上看到过江南水乡以前的美丽风景，山上有郁郁葱葱的树木，满山遍地开花，还有清得可见底的山涧，以前，在这种美景还在的时候，只要，伸手进去，就会摸到一串夏日时青蛙产下的卵……可是现在，各大化工企业都排出恶心的污水，我们都不敢伸手了。当我们想伸手时，妈妈就吓我们说：“碰了黑水手会烂的！”这下，我终于明白了：不治污水，污水泛滥，水不能喝了，会臭水的，所以要节水……
原来，江南水乡一片片绿绿的水，蓝蓝的天。可现在，全是黑、灰这单调的颜色，我很讨厌。
“五水共治”确实很重要，如果不遵守“五水共治”里的几项规定，严重破坏了水中生物的家园与生活。
五水共治中最重要的就是抓节水了，你要想：人不节水，水被用光了，能喝的水都没了，做饭都没水了，喝污水，那你还不恶心？到没水的时候，你还不得渴死了？所以，节水很重要！节水这项工程还是需要大家共同努力的，水没了，那前面的四项都用不上了，人也要死了，那多不好！再说了，只有这一项是我们力所能及的，可以从自己做起的。
还有一条“治污水”这个也是靠我们一起合作完成的小部分，只要不让白色垃圾污染河流就可以了，可有些人却不会这样，老往河里扔垃圾。
哎，“五水共治”太难了，但是，只要尽力而为，都没关系，我相信，只要大家都努力了，就可以把这“五水”治好！她以她那丰富的乳汁哺育着我们，呵护着我们的成长，不能让他毁在我们的手上，我们应该让他更好！
