汽車及其零部件的塗裝是汽車製造過程中產生廢水排放最多的環節之一。塗裝廢水含有樹脂、表面活性劑、重金屬離子，Oil、PO43-、油漆、顏料、有機溶劑等污染物，CODCr值高，若不妥善處理，會對環境產生嚴重污染。對此類廢水，傳統的方法是直接對混合廢水進行混凝處理，治理效果不理想，出水水質不穩定，較難達到排放標准。特別是其中的噴漆廢水，含大量溶於水的有機溶劑，直接採用混凝法處理效果很差。我們在上海某汽車廠經過實地勘查、大量分析調研和小試，針對塗裝廢水的特點，採用分質預處理再進行後續處理的二步處理的方法，並選擇芬頓氧化—混凝沉澱，氣浮物化工藝進行處理，達到了排放標准，CODCr去除率達到80%以上。
1廢水的來源和主要污染物
1.1 塗裝廢水的來源及有害物質

2．塗裝廢水處理工藝設計
汽車塗裝廢水處理工藝的關鍵之一在於合理的清濁分質。對部分難處理或影響後續處理的廢水，根據其性質和排放規律，先進行間歇的預處理，再和其它廢水集中連續處理，這樣不僅可以取得較好的和穩定的處理效果，而且在經濟上也合理可行。
2.1 塗裝廢水處理工藝流程
塗裝廢水處理工藝流程如圖1所示。
圖1某汽車廠塗裝廢水處理站處理流程
2.2 間歇預處理
2.2.1 脫脂廢液
對脫脂廢液採用酸化法進行破乳預處理，向脫脂廢液中投加無機酸將pH調至2～3，使乳化劑中的高級脂肪酸皂析出脂肪酸，這些高級脂肪酸不溶於水而溶於油，從而使脫脂廢液破乳析油。
另外，加酸後使脫脂廢液中的陰離子表面活性劑在酸性溶液中易分解而失去穩定性，失去了原有的親油和親水的平衡，從而達到破乳。經預處理後CODCr從2500～4000mg/L降低到1500～2400mg/L，去除率在40%左右；而含油量從300～950 mg/L降至50～70 mg/L，去除率高達90%～95%。
2.2.2 電泳廢液
在陰極電泳廢水中含有大量高分子有機物，CODCr最高可達20000mg/L，還含大量電泳渣，這些物質在水中呈細小懸浮物或呈負電性的膠體狀。處理中加入適當的陽離子型聚丙烯醯胺（PAM）和聚合氯化鋁（PAC）作混凝劑，利用絮凝劑的吸附架橋作用來快速去除廢水中的污染物。電泳廢液在預處理時要求pH值在11～12之間，有較好的沉澱效果。反應後的出水CODCr在2000 mg/L左右。
2.2.3 噴漆廢水
對噴漆廢水先採用Fenton試劑（H2O2+FeSO4）對其進行預處理，使其中的有機物氧化分解，CODCr去除效率約在30%左右，再加入PAC和PAM對其進行混凝沉澱，經過此兩步處理，CODCr的總去除率可達到60%～80％，由3000～20000mg/L降至1200～4000mg/L。出水排入混合廢水調節池。
Fenton試劑具有很強的氧化能力，當pH值較低時（控制在3左右），H2O2被Fe2+催化分解生成羥基自由基（·OH），並引發更多的其他自由基，從而引發一系列的鏈反應[1]。通過具有極強的氧化能力的·OH與有機物的反應，使廢水中的難降解有機物發生部分氧化、使廢水中的有機物C—C鍵斷裂，最終分解成H2O、CO2等，使CODCr降低。或者發生偶合或氧化，改變其電子雲密度和結構，形成分子量不太大的中間產物，從而改變它們的溶解性和混凝沉澱性。同時，Fe2+被氧化生成Fe(OH)3在一定酸度下以膠體形態存在，具有凝聚、吸附性能，還可除去水中部分懸浮物和雜質。出水通過後續的混凝沉澱進一步去除污染物，以達到凈化的目的[2]。
2.3 連續處理
經預處理的各類廢水排入均和調節池中，與其它廢水混合後進入連續處理流程。混合後的廢水CODCr約為700～900mg/L。連續處理分為二級：混凝沉澱和混凝氣浮。
在塗裝廢水中，油、高分子樹脂（環氧樹脂）、顏料（碳黑）、粉劑、磷酸鹽等在表面活性劑、溶劑及各種助劑的作用下，以膠體的形式穩定地分散在水溶液中。可以靠投加化學葯劑來破壞膠體的細微懸浮顆粒在水中形成的穩定體系，使其聚集成有明顯沉澱性能的絮凝體，然後形成沉澱或浮渣加以除去[3]。
在廢水中加入一定量的無機絮凝劑後，它們可中和乳化油或高分子樹脂的電位，壓縮雙電層，膠粒碰撞促進凝集，完成脫穩過程，形成細小密實的絮凝物。這樣可使塗裝廢水中的金屬離子和磷酸根離子在鹼性條件下生成的固體小顆粒形成沉澱物[4]。所以混凝處理可有效地去除汽車塗裝廢水中的油、高分子樹脂、顏料和粉劑[5]。
重金屬離子和磷酸鹽中，由於Ni2+生成Ni(OH)2沉澱以及PO43-生成Ca3 (PO4) 2沉澱的最佳pH值是10以上；而Zn2+生成氫氧化物沉澱的最佳pH值范圍是8.5～9.5，pH過高會形成ZnO22－而溶解。所以要分二級混凝反應以分別去除Ni2+，PO43-和Zn2+ 。同時，混凝反應後的固液分離分別採用的是斜板沉澱池和氣浮池，這樣既可以用斜板沉澱池來去除比重較大的重金屬化合物沉澱，又可以用氣浮池來去除比重較輕的有機物等。
2.3.1 混凝沉澱
第一級為混凝沉澱調節pH值為10～10.5。
反應槽採用推流式反應槽，分為三格。第一格加鹼將pH調高至10～10.5，加入CaCl2，第二格加FeSO4，第三格加混凝劑PAM，反應後進入斜板沉澱池進行固液分離。三格停留時間分別為15min、15min、7.5min。斜板沉澱池表面負荷按2m3/m2·h設計。一級反應CODCr去除率為50%～60%。圖2為一級反應槽示意圖。
圖2 一級反應槽示意圖
2.3.2 混凝氣浮
二級反應的反應槽，也採用推流式反應槽，分為三格。第一格加酸將pH回調至8.5～9，第二格加PAC，第三格加PAM，反應後進入氣浮池進行固液分離。二級反應槽三格停留時間分別為10min、10min、5min。氣浮池的溶氣水按處理水量的30%設計。二級反應CODCr去除率為20%～25%，同時氣浮也去除了Zn2+和一部分的表面活性劑。
2.4 深度處理
深度處理採用砂濾和活性炭過濾。從運行情況看，經砂濾後的出水即能達到排放標准（CODCr≤300mg/L）。砂濾裝置的過濾速度控制在10～12m3/（m2·h）。反沖洗水由監測水箱中的水加壓後提供，反沖洗強度控制在16～18L/（m2·s）。
砂濾後的出水已能達到排放要求，因此，活性炭過濾只是一個應急保證措施，一般情況下較少使用。
2.5 污泥處理
污泥處理的好壞，直接影響廢水處理站的運行。由於污泥含油量高，直接進行壓濾效果較差，在污泥濃縮槽中加入Ca（OH）2，pH調整至10左右，能達到較好的壓濾效果。污泥含水率經板框壓濾機後可由99%下降至75%～80%。
2.6 連續處理去除率分析
連續處理過程去除率如表3所示。

斜板沉澱池出口 50%～60%
氣浮池出口 20%～25%

*廢水處理裝置進口指連續處理裝置進口。
** Zn2+、Mn2+、Ni2+本次監測未分析，表中所列為該廠廢水處理站日常分析數據。
由上表可以看出，經處理後的廢水以上海市《污水綜合排放標准》（DB31/199—1997）進行評價，其中CODCr、BOD5、SS按三級標准評價（廢水處理後排入安亭水質凈化廠），其餘採用二級標准及第一類污染物最高允許排放濃度，均能達到工程設計指標。
目前，處理裝置運行穩定，出水均能達標。
4．技術經濟分析
工程造價和運行費用是人們在選用處理方法時所必須考慮和關心的問題。本工程採用分質處理後，與一般的集中物化處理比較，節省了加葯量，污泥產量也有所減少，在一定程度上減少了運行費用，更重要的是保證了出水水質的穩定達標。本項目的技術經濟指標見表5。

5．結論
1、本工程採用分質處理、混凝沉澱、混凝氣浮、砂濾等工藝對汽車塗裝廢水進行處理在技術和經濟上是合理可行的。實際運行結果證明，此工藝對重金屬、SS、Oil的去除效率超過90%，對CODCr的去除率大於80%。
2、汽車塗裝廢水水量和水質變化大，要特別的重視廢水水量、水質均衡和分質預處理。根據工程實踐證明，對脫脂廢液，電泳廢水、廢液和噴漆廢水這三股廢水分別進行間歇預處理，這不僅有利於後續處理效率的提高，體現出技術和經濟的統一，而且對整個系統的穩定運行和出水的穩定達標至關重要。

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 求廢水處理英文文獻一篇
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.).
㈨ 有關污水排放建議的英語作文帶翻譯
處理污水，造福人類
Sewage, the benefit of mankind
隨著科學技術的進步，幾乎每個城市都有許多的工廠，工廠里每天排出的污水都污染了許多江河、湖泊，導致大部分的魚蝦中毒死亡；同時也威脅這自然界里的生物和人類的安危，對人類的生活造成了極大的影響。
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.
我時常幻想著，假如這些污水經過處理，變成干凈的、能飲用的水，那該多好啊！於是我就想到了需要一種能隨意變大變小的「污水處理儀器」，我把它簡稱為「處污器」。它可以放在家裡、學校里、也可以安裝在工廠里。這個「處污器」是個正方形，外殼是一種踩不爛壓不扁的塑料；它的心臟是由一塊伸縮自如且永久使用的過濾網，一個具有除臭功能且永不變形的旋轉筒和一片微型的智能電動晶元組成。這個「處污器」的電是用之不竭的，只要有一絲光亮，它就立刻把光能轉化為電能，非常環保。這個「處污器」可以自動計算需要排出的污水量，然後根據排污量來改變自己的大小。比如：一間造紙廠每天生產一噸紙，只要你輕輕按紅色按鈕，它就自動計算出這間工廠的排污量，根據排污量把自己變大。再輕輕一按綠色按鈕，「處污器」馬上開始工作。污水流經入口的過濾網，所有的大大小小的垃圾就會被過濾掉。沒有垃圾的污水直接流入旋轉筒，旋轉筒不停地轉動去除臭味，再凈化。同時，它會加入人體所需要的礦物質和微量元素，然後再通過出口排出來。這些經過處理的水非常神奇，人們喝了既可以美容又可以強身健體，少生病。動物喝了會更肥壯，再兇猛的動物喝了也會變得善良可愛。這些水用來澆灌禾苗，稻穀的產量會更高。這個「處污器」放在家裡的時候，它會自動變小。家裡的生活用水經過「處污器」可以循環利用。這樣，我們不但達到了節約用水的目的，還保護了地球的生態環境。想到這里，我彷彿就生活在一個綠樹成蔭、鳥語花香、物產豐富、山清水秀……沒有一絲污染的國家裡。
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.
