㈠ 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!

1.4工艺简介
采用A/A/O处理工艺
重庆市某污水处理厂二期处理程度为一级处理、二级生物处理、消毒及污泥处理，执行中华人民共和国国家标准GB8978—1996《污水综合排放标准》中的一级标准，即：BOD5≤20mg/1，SS≤20mg/1，CODcr≤60mg/1，NH3-N≤15mg/1，TP≤0.5mg/1。
该污水处理厂采用A/A/O生化处理工艺。它是在A/O工艺基础上增加了一个缺氧区，具有同步脱氮除磷的功能。
A/A/O工艺处理污水首先进入厌氧区，兼性厌氧发酵细菌将污水中可生物降解的有机物转化为VFA（挥发性脂肪酸类）这类低分子发酵中间产物。而聚磷菌可将其体内存储的聚磷酸盐分解，所释放的能量可供好氧的聚磷菌在厌氧环境下维持生存，另一部分能量还可供聚磷菌主动吸收环境中的VFA类低分子有机物，并以PHB（聚羟β丁酸）的形式在其体内储存起来。随后污水进入缺氧区，反硝化菌就利用好氧区回流混合液带来的硝酸盐，以及污水中可生物降解有机物作碳源进行反硝化，达到同时降低BOD5与脱氮的目的。接着污水进入曝气的好氧区，聚磷菌在吸收、利用污水中残剩的可生物降解有机物的同时，主要是通过分解体内储存的PHB释放能量来维持其生长繁殖。同时过量的摄取周围环境中的溶解磷，并以聚磷的形式在体内储积起来，使出水中溶解磷浓度达到最低。而有机物经厌氧区、缺氧区分别被聚磷和反硝化细菌利用后，到达好氧区时浓度已相当低，这有利于自养型硝化菌的生长繁殖，并通过硝化作用将氨氮转化为硝酸盐。非除磷的好氧性异养菌虽然也能存在，但他在厌氧区中受到严重的压抑，在好氧区又得不到充足的营养，因此在与其他生理类群的微生物竞争中处于相对劣势。排放的剩余污泥中，由于含有大量能超量储积聚磷的聚磷菌，污泥含磷量可以达到6%（干重）以上。从以上分析可以看出A/A/O工艺具有同步脱氮除磷的功能。
A/A/O工艺的优点是厌氧、缺氧、好氧交替运行，可以达到同时去除有机物、脱氮、除磷的目的，而且这种运行状况丝状菌不宜生长繁殖，基本不存在污泥膨胀问题。A/A/O工艺流程简单，总水力停留时间少于其他同类工艺，并且不需外加碳源，缺氧、缺氧段只进行缓速搅拌，运行费用低。
雨、污水经过上述处理合格，符合国家排放标准的污水直接排入长江。

㈥ 求助！！生活污水处理的外文文献
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.).
