汽车及其零部件的涂装是汽车制造过程中产生废水排放最多的环节之一。涂装废水含有树脂、表面活性剂、重金属离子，Oil、PO43-、油漆、颜料、有机溶剂等污染物，CODCr值高，若不妥善处理，会对环境产生严重污染。对此类废水，传统的方法是直接对混合废水进行混凝处理，治理效果不理想，出水水质不稳定，较难达到排放标准。特别是其中的喷漆废水，含大量溶于水的有机溶剂，直接采用混凝法处理效果很差。我们在上海某汽车厂经过实地勘查、大量分析调研和小试，针对涂装废水的特点，采用分质预处理再进行后续处理的二步处理的方法，并选择芬顿氧化—混凝沉淀，气浮物化工艺进行处理，达到了排放标准，CODCr去除率达到80%以上。
1废水的来源和主要污染物
1.1 涂装废水的来源及有害物质

2．涂装废水处理工艺设计
汽车涂装废水处理工艺的关键之一在于合理的清浊分质。对部分难处理或影响后续处理的废水，根据其性质和排放规律，先进行间歇的预处理，再和其它废水集中连续处理，这样不仅可以取得较好的和稳定的处理效果，而且在经济上也合理可行。
2.1 涂装废水处理工艺流程
涂装废水处理工艺流程如图1所示。
图1某汽车厂涂装废水处理站处理流程
2.2 间歇预处理
2.2.1 脱脂废液
对脱脂废液采用酸化法进行破乳预处理，向脱脂废液中投加无机酸将pH调至2～3，使乳化剂中的高级脂肪酸皂析出脂肪酸，这些高级脂肪酸不溶于水而溶于油，从而使脱脂废液破乳析油。
另外，加酸后使脱脂废液中的阴离子表面活性剂在酸性溶液中易分解而失去稳定性，失去了原有的亲油和亲水的平衡，从而达到破乳。经预处理后CODCr从2500～4000mg/L降低到1500～2400mg/L，去除率在40%左右；而含油量从300～950 mg/L降至50～70 mg/L，去除率高达90%～95%。
2.2.2 电泳废液
在阴极电泳废水中含有大量高分子有机物，CODCr最高可达20000mg/L，还含大量电泳渣，这些物质在水中呈细小悬浮物或呈负电性的胶体状。处理中加入适当的阳离子型聚丙烯酰胺（PAM）和聚合氯化铝（PAC）作混凝剂，利用絮凝剂的吸附架桥作用来快速去除废水中的污染物。电泳废液在预处理时要求pH值在11～12之间，有较好的沉淀效果。反应后的出水CODCr在2000 mg/L左右。
2.2.3 喷漆废水
对喷漆废水先采用Fenton试剂（H2O2+FeSO4）对其进行预处理，使其中的有机物氧化分解，CODCr去除效率约在30%左右，再加入PAC和PAM对其进行混凝沉淀，经过此两步处理，CODCr的总去除率可达到60%～80％，由3000～20000mg/L降至1200～4000mg/L。出水排入混合废水调节池。
Fenton试剂具有很强的氧化能力，当pH值较低时（控制在3左右），H2O2被Fe2+催化分解生成羟基自由基（·OH），并引发更多的其他自由基，从而引发一系列的链反应[1]。通过具有极强的氧化能力的·OH与有机物的反应，使废水中的难降解有机物发生部分氧化、使废水中的有机物C—C键断裂，最终分解成H2O、CO2等，使CODCr降低。或者发生偶合或氧化，改变其电子云密度和结构，形成分子量不太大的中间产物，从而改变它们的溶解性和混凝沉淀性。同时，Fe2+被氧化生成Fe(OH)3在一定酸度下以胶体形态存在，具有凝聚、吸附性能，还可除去水中部分悬浮物和杂质。出水通过后续的混凝沉淀进一步去除污染物，以达到净化的目的[2]。
2.3 连续处理
经预处理的各类废水排入均和调节池中，与其它废水混合后进入连续处理流程。混合后的废水CODCr约为700～900mg/L。连续处理分为二级：混凝沉淀和混凝气浮。
在涂装废水中，油、高分子树脂（环氧树脂）、颜料（碳黑）、粉剂、磷酸盐等在表面活性剂、溶剂及各种助剂的作用下，以胶体的形式稳定地分散在水溶液中。可以靠投加化学药剂来破坏胶体的细微悬浮颗粒在水中形成的稳定体系，使其聚集成有明显沉淀性能的絮凝体，然后形成沉淀或浮渣加以除去[3]。
在废水中加入一定量的无机絮凝剂后，它们可中和乳化油或高分子树脂的电位，压缩双电层，胶粒碰撞促进凝集，完成脱稳过程，形成细小密实的絮凝物。这样可使涂装废水中的金属离子和磷酸根离子在碱性条件下生成的固体小颗粒形成沉淀物[4]。所以混凝处理可有效地去除汽车涂装废水中的油、高分子树脂、颜料和粉剂[5]。
重金属离子和磷酸盐中，由于Ni2+生成Ni(OH)2沉淀以及PO43-生成Ca3 (PO4) 2沉淀的最佳pH值是10以上；而Zn2+生成氢氧化物沉淀的最佳pH值范围是8.5～9.5，pH过高会形成ZnO22－而溶解。所以要分二级混凝反应以分别去除Ni2+，PO43-和Zn2+ 。同时，混凝反应后的固液分离分别采用的是斜板沉淀池和气浮池，这样既可以用斜板沉淀池来去除比重较大的重金属化合物沉淀，又可以用气浮池来去除比重较轻的有机物等。
2.3.1 混凝沉淀
第一级为混凝沉淀调节pH值为10～10.5。
反应槽采用推流式反应槽，分为三格。第一格加碱将pH调高至10～10.5，加入CaCl2，第二格加FeSO4，第三格加混凝剂PAM，反应后进入斜板沉淀池进行固液分离。三格停留时间分别为15min、15min、7.5min。斜板沉淀池表面负荷按2m3/m2·h设计。一级反应CODCr去除率为50%～60%。图2为一级反应槽示意图。
图2 一级反应槽示意图
2.3.2 混凝气浮
二级反应的反应槽，也采用推流式反应槽，分为三格。第一格加酸将pH回调至8.5～9，第二格加PAC，第三格加PAM，反应后进入气浮池进行固液分离。二级反应槽三格停留时间分别为10min、10min、5min。气浮池的溶气水按处理水量的30%设计。二级反应CODCr去除率为20%～25%，同时气浮也去除了Zn2+和一部分的表面活性剂。
2.4 深度处理
深度处理采用砂滤和活性炭过滤。从运行情况看，经砂滤后的出水即能达到排放标准（CODCr≤300mg/L）。砂滤装置的过滤速度控制在10～12m3/（m2·h）。反冲洗水由监测水箱中的水加压后提供，反冲洗强度控制在16～18L/（m2·s）。
砂滤后的出水已能达到排放要求，因此，活性炭过滤只是一个应急保证措施，一般情况下较少使用。
2.5 污泥处理
污泥处理的好坏，直接影响废水处理站的运行。由于污泥含油量高，直接进行压滤效果较差，在污泥浓缩槽中加入Ca（OH）2，pH调整至10左右，能达到较好的压滤效果。污泥含水率经板框压滤机后可由99%下降至75%～80%。
2.6 连续处理去除率分析
连续处理过程去除率如表3所示。
表3 连续处理效率
出水位置 CODCr去除率
斜板沉淀池出口 50%～60%
气浮池出口 20%～25%
砂滤出口 15%

该工程自2002年运行至今，处理效果稳定，表4为上海市环境监测中心2004年对该厂的监测分析报告数据汇总。监测时间为3天，每天取样12次（1小时取样一次，包括废水处理装置进口和出口）。

由上表可以看出，经处理后的废水以上海市《污水综合排放标准》（DB31/199—1997）进行评价，其中CODCr、BOD5、SS按三级标准评价（废水处理后排入安亭水质净化厂），其余采用二级标准及第一类污染物最高允许排放浓度，均能达到工程设计指标。
目前，处理装置运行稳定，出水均能达标。
4．技术经济分析
工程造价和运行费用是人们在选用处理方法时所必须考虑和关心的问题。本工程采用分质处理后，与一般的集中物化处理比较，节省了加药量，污泥产量也有所减少，在一定程度上减少了运行费用，更重要的是保证了出水水质的稳定达标。本项目的技术经济指标见表5。

5．结论
1、本工程采用分质处理、混凝沉淀、混凝气浮、砂滤等工艺对汽车涂装废水进行处理在技术和经济上是合理可行的。实际运行结果证明，此工艺对重金属、SS、Oil的去除效率超过90%，对CODCr的去除率大于80%。
2、汽车涂装废水水量和水质变化大，要特别的重视废水水量、水质均衡和分质预处理。根据工程实践证明，对脱脂废液，电泳废水、废液和喷漆废水这三股废水分别进行间歇预处理，这不仅有利于后续处理效率的提高，体现出技术和经济的统一，而且对整个系统的稳定运行和出水的稳定达标至关重要。

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!

㈧ 求废水处理英文文献一篇
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.).

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!
