④ 写一篇关于污水的作文大全
今天，学校的科技节开幕了。今年的主题是环保，就是低碳生活、节能减排。
说起环境保护，我不禁想起了《读者》上的一篇我认为很好的文章——《莱茵河为何总是清的》。德国莱茵河素来以清澈闻名。在德国境内，莱茵河畔有大大小小企业3000多家，它们所产生的污水绝不在少量，可莱茵河的水为什么总是那么清呢?
在许多国家看来，污水处理是一个很大的负担，因为需要采购大量设备、仪器，还要长期配备工人、电力、物力等，负担自然不小。然而，对于德国企业来说，处理污水并不意味着增加成本，而是一项有收益的产业投资。以德国杜伊斯堡为例，有三家大型企业合建了一个污水处理厂，使之成为一家独立的股份制企业，再由政府派人、出钱来监督管理。原本应由三家企业各自承担的污水处理系统，现在变成了三家共同承担。如果附近有新企业成立，政府便会建议他们挖一条管道把污水排进那三家企业合建的污水处理厂就行了，虽然这家企业要交一笔不菲的费用，但与建设污水处理系统相比根本不值一提。这就是污水处理厂可以产生的效益。同样，这座城市53万人口的生活污水也排进这家污水处理厂，每位市民根据各自使用量缴纳50%的污水处理费。对于这项有明确用途且为数不多的费用，全德国无人反对。这项费用也是污水处理厂的利润。再加上那些处理干净的水又会被循环利用，或以低价出售给企业和庄园，这又是一笔可观的收入。
由此，我们就不难理解莱茵河的水为什么总是清的了，也不难理解我们的母亲河长江、黄河为什么总是“污不忍睹”了!人为利死，鸟为食亡。人总喜欢做对自己有利的事情。在我国，企业认为建设、运营污水处理系统很费人力、物力、财力，是企业的一个负担，再说乱排污水又不会被罚或罚得很少，谁还会做污水处理的“傻事”。于是有些企业的污水处理设备只是做做样子，只有上面来检查时才会开启，检查组走了就关停，污水照样乱排。而德国企业认为污水处理是有利可图的，所以非常乐意做，以致于德国政府只能暂停审批建设新的污水处理厂。
好孩子是夸出来的，而不是打罚出来的。我认为污水处理也一样。如果我们能学习德国人的做法，使污水处理从企业的负担变成利润，结果将会发生根本改变。因为只罚不奖未必有效果，只有奖罚并用才能出现良好效果。
有时候问题不是出在别人身上，而是在源头自身，改变自己的同时，世界也随之改变。今天的日记请让我用杜伊斯堡市市长的话来结束：
如果一提公益就意味着要增加某些人的负担，显然这不是真正的公益。我们提倡但不依靠人们主动去做公益事业，也不施压力逼迫人们去做，而是用我们的智慧去规划和部署，让公益事业也成为一种盈利事业，从而实现真正的公益。
⑤ 治理废水的措施初三英语作文带翻译
成长,就好比我人生中的一艘小船,行驶在波面上.有时风平浪静,有时也会遇到汹涌澎湃的海浪.但我的成长之舟,并不是一帆风顺的,其中也经历着各种风波.对我而言,酸甜苦辣咸,样样都有.
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.
回想起自己小的时候,生活是多么轻松,无忧无虑,自由自在,身边根本就没什么烦恼.但是随着岁月的流逝,前方的海浪也更大了,海面也更波折了,我成为一个小学生了,往日那个我已经荡然无存了.我个子高了,上学时间长了,回家作业增了,学习科目多了,我的双肩背起了更重的书包,心中的压力也不断加重.如果是小时候,我无论做错什么事,没有人会来责怪我,再加上还有父母为我当“向导”.可现在的我,长大了,懂事了,要适应独立了,凡是做事都要小心翼翼,三思而后行.这与小时候那悠闲自在的日子相比也渐渐地拉开了距离.
小时候,身为小孩子的我,虽然生活地会自在些,可是我却处处受着长辈与他人的约束,走路时,有父母掺着；摔倒了,有父母扶着.但是我知道,在自己长大了
⑥ 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!

⑧ 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.).
