隨著電鍍污染物排放標準的發布，特別是對污水中COD去除要求，引起了不少電鍍企業的廣泛重視，由于采用常規化學沉淀法處理效果并不穩定，容易出現超標情況，特別是一些絡合態的重金屬產品更是難以達到新標準的要求。

原因塑(su)(su)料電鍍層鋅生產(chan)方(fang)式制(zhi)作工(gong)(gong)(gong)藝技(ji)術(shu)各不是(shi)一樣的(de)，主產(chan)生的(de)塑(su)(su)料電鍍層鋅化(hua)(hua)工(gong)(gong)(gong)廢(fei)氣(qi)的(de)特點也各不是(shi)一樣的(de)，故此塑(su)(su)料電鍍層鋅化(hua)(hua)工(gong)(gong)(gong)廢(fei)氣(qi)清理工(gong)(gong)(gong)學(xue)藝技(ji)術(shu)應只能(neng)根據化(hua)(hua)工(gong)(gong)(gong)廢(fei)氣(qi)方(fang)式、水(shui)的(de)質量(liang)來選(xuan)取。

般鍍膜中小企業(ye)所排出到的廢(fei)(fei)(fei)污水(shui)(shui)以(yi)及有酸、堿等前工作(zuo)廢(fei)(fei)(fei)污水(shui)(shui)，氰化鍍銅的含鉻廢(fei)(fei)(fei)污水(shui)(shui)、含氰廢(fei)(fei)(fei)污水(shui)(shui)等天價屬廢(fei)(fei)(fei)污水(shui)(shui)，更有就是更有多鍍膜廢(fei)(fei)(fei)水(shui)(shui)引(yin)起。

談談有(you)差(cha)異 于(yu)內(nei)型生活污水(shui)，有(you)有(you)差(cha)異 于(yu)鍍膜生活污水(shui)加工(gong)步驟，各自(zi)介紹一(yi)下以下：

1、含鉻污廢水 ——鉻回歸法  

含鉻(ge)塑膠電鍍焦化(hua)(hua)廢(fei)水普通(tong)分為鉻(ge)完(wan)美(mei)重現法來清理，方(fang)式是在弱酸(suan)性能力下(xia)，加藥(yao)完(wan)美(mei)重現劑鹽(yan)酸(suan)亞鐵、亞鹽(yan)酸(suan)氫鈉(na)、亞鹽(yan)酸(suan)鈉(na)、二(er)陽(yang)(yang)(yang)極鈍(dun)化(hua)(hua)反(fan)應(ying)(ying)(ying)硫等(deng)，將六(liu)價(jia)鉻(ge)完(wan)美(mei)重現成(cheng)三價(jia)鉻(ge)，第二(er)加藥(yao)氫陽(yang)(yang)(yang)極鈍(dun)化(hua)(hua)反(fan)應(ying)(ying)(ying)鈣、氫陽(yang)(yang)(yang)極鈍(dun)化(hua)(hua)反(fan)應(ying)(ying)(ying)鈉(na)、陽(yang)(yang)(yang)極氧化(hua)(hua)鈣等(deng)，調pH值，使其繪制三價(jia)鉻(ge)氫陽(yang)(yang)(yang)極鈍(dun)化(hua)(hua)反(fan)應(ying)(ying)(ying)物(wu)濾渣從焦化(hua)(hua)廢(fei)池中分割(ge)。

2、含氰污水——咸性氯化法操作

現今工(gong)作含氰(qing)塑膠電(dian)(dian)鍍(du)層污水(shui)(shui)多采(cai)取酸(suan)性氯化法工(gong)作，需(xu)用注(zhu)意事項(xiang)含氰(qing)污水(shui)(shui)與另一個污水(shui)(shui)從嚴分(fen)科，禁(jin)止摻入鎳、鐵等(deng)不銹鋼陰離子，如果塑膠電(dian)(dian)鍍(du)層污水(shui)(shui)工(gong)作下去會很不便。

的原理是廢(fei)氣在酸堿度要(yao)求(qiu)下，按照氯系被(bei)氧化反應將(jiang)氰化物嚴重破壞而刪去的的辦法，治(zhi)理 時段(duan).可分為二個時段(duan).：

一將氰脫(tuo)色(se)為(wei)氰酸鹽(yan)，對氰嚴重破(po)壞不(bu)全面，稱為(wei)不(bu)非常(chang)脫(tuo)色(se)一階段中；二(er)將氰酸鹽(yan)進一大步(bu)脫(tuo)色(se)拆分成二(er)脫(tuo)色(se)碳和水，叫(jiao)非常(chang)脫(tuo)色(se)一階段中。

3、綜合性天價屬工業廢水——氫空氣化合物沉淀物的技術

綜合(he)天(tian)價屬廢氣是由含銅、鎳(nie)、鋅等(deng)非絡(luo)合(he)物的(de)天(tian)價屬廢氣，同時(shi)酸、堿前解(jie)決廢氣所結構。類似于化(hua)學(xue)鍍(du)廢氣解(jie)決技(ji)巧較(jiao)為單(dan)純，主要采用咸性要求下轉成(cheng)氫被化(hua)合(he)物積累(lei)的(de)技(ji)藝就能。

方法(fa)方法(fa)為：全方位的血本屬焦化(hua)廢(fei)水(shui)→調結池(chi)→快混池(chi)→慢混池(chi)→斜管結晶池(chi)→過慮→pH調整池(chi)→尾(wei)氣排放(fang)。

4、三種真空鍍膜污污水 基礎性清理——污污水 分配清理

當鍍(du)膜廠包(bao)含很(hen)多(duo)廢氣(qi)(qi)(qi)加(jia)(jia)(jia)(jia)工(gong)實(shi)(shi)(shi)行(xing)(xing)(xing)(xing)(xing)(xing)除(chu)(chu)(chu)理(li)(li)(li)(li)(li)辦(ban)(ban)(ban)法(fa)(fa)(fa)時(shi)（如含鉻廢氣(qi)(qi)(qi)加(jia)(jia)(jia)(jia)工(gong)實(shi)(shi)(shi)行(xing)(xing)(xing)(xing)(xing)(xing)除(chu)(chu)(chu)理(li)(li)(li)(li)(li)辦(ban)(ban)(ban)法(fa)(fa)(fa)、含氰廢氣(qi)(qi)(qi)加(jia)(jia)(jia)(jia)工(gong)實(shi)(shi)(shi)行(xing)(xing)(xing)(xing)(xing)(xing)除(chu)(chu)(chu)理(li)(li)(li)(li)(li)辦(ban)(ban)(ban)法(fa)(fa)(fa)、含酸堿性、血本屬等(deng)合(he)理(li)(li)(li)(li)(li)廢氣(qi)(qi)(qi)加(jia)(jia)(jia)(jia)工(gong)實(shi)(shi)(shi)行(xing)(xing)(xing)(xing)(xing)(xing)除(chu)(chu)(chu)理(li)(li)(li)(li)(li)辦(ban)(ban)(ban)法(fa)(fa)(fa)），鍍(du)膜廢氣(qi)(qi)(qi)加(jia)(jia)(jia)(jia)工(gong)實(shi)(shi)(shi)行(xing)(xing)(xing)(xing)(xing)(xing)除(chu)(chu)(chu)理(li)(li)(li)(li)(li)辦(ban)(ban)(ban)法(fa)(fa)(fa)加(jia)(jia)(jia)(jia)工(gong)實(shi)(shi)(shi)行(xing)(xing)(xing)(xing)(xing)(xing)除(chu)(chu)(chu)理(li)(li)(li)(li)(li)工(gong)學藝基本考慮廢氣(qi)(qi)(qi)加(jia)(jia)(jia)(jia)工(gong)實(shi)(shi)(shi)行(xing)(xing)(xing)(xing)(xing)(xing)除(chu)(chu)(chu)理(li)(li)(li)(li)(li)辦(ban)(ban)(ban)法(fa)(fa)(fa)過(guo)渡加(jia)(jia)(jia)(jia)工(gong)實(shi)(shi)(shi)行(xing)(xing)(xing)(xing)(xing)(xing)除(chu)(chu)(chu)理(li)(li)(li)(li)(li)法(fa)(fa)(fa)，含鉻廢氣(qi)(qi)(qi)加(jia)(jia)(jia)(jia)工(gong)實(shi)(shi)(shi)行(xing)(xing)(xing)(xing)(xing)(xing)除(chu)(chu)(chu)理(li)(li)(li)(li)(li)辦(ban)(ban)(ban)法(fa)(fa)(fa)、含氰廢氣(qi)(qi)(qi)加(jia)(jia)(jia)(jia)工(gong)實(shi)(shi)(shi)行(xing)(xing)(xing)(xing)(xing)(xing)除(chu)(chu)(chu)理(li)(li)(li)(li)(li)辦(ban)(ban)(ban)法(fa)(fa)(fa)從產(chan)出線分開(kai)過(guo)渡抽取后，各分為決定所訴(su)相應的(de)的(de)辦(ban)(ban)(ban)法(fa)(fa)(fa)對(dui)含鉻、含氰廢氣(qi)(qi)(qi)加(jia)(jia)(jia)(jia)工(gong)實(shi)(shi)(shi)行(xing)(xing)(xing)(xing)(xing)(xing)除(chu)(chu)(chu)理(li)(li)(li)(li)(li)辦(ban)(ban)(ban)法(fa)(fa)(fa)實(shi)(shi)(shi)行(xing)(xing)(xing)(xing)(xing)(xing)加(jia)(jia)(jia)(jia)工(gong)實(shi)(shi)(shi)行(xing)(xing)(xing)(xing)(xing)(xing)除(chu)(chu)(chu)理(li)(li)(li)(li)(li)，加(jia)(jia)(jia)(jia)工(gong)實(shi)(shi)(shi)行(xing)(xing)(xing)(xing)(xing)(xing)除(chu)(chu)(chu)理(li)(li)(li)(li)(li)后的(de)廢氣(qi)(qi)(qi)加(jia)(jia)(jia)(jia)工(gong)實(shi)(shi)(shi)行(xing)(xing)(xing)(xing)(xing)(xing)除(chu)(chu)(chu)理(li)(li)(li)(li)(li)辦(ban)(ban)(ban)法(fa)(fa)(fa)摻拌在合(he)理(li)(li)(li)(li)(li)廢氣(qi)(qi)(qi)加(jia)(jia)(jia)(jia)工(gong)實(shi)(shi)(shi)行(xing)(xing)(xing)(xing)(xing)(xing)除(chu)(chu)(chu)理(li)(li)(li)(li)(li)辦(ban)(ban)(ban)法(fa)(fa)(fa)中和(he)其一塊兒(er)用(yong)到混泥土濾渣辦(ban)(ban)(ban)法(fa)(fa)(fa)實(shi)(shi)(shi)行(xing)(xing)(xing)(xing)(xing)(xing)后期加(jia)(jia)(jia)(jia)工(gong)實(shi)(shi)(shi)行(xing)(xing)(xing)(xing)(xing)(xing)除(chu)(chu)(chu)理(li)(li)(li)(li)(li)。

很多電鍍鋅污(wu)水處里藝操作流程(cheng)相應:

含(han)鉻廢(fei)渣→控制池→鉻恢復原池→綜合管理廢(fei)渣池；

含氰電鍍(du)廢水(shui)(shui)→調(diao)低池(chi)(chi)→4級破氰池(chi)(chi)→二次(ci)元破氰池(chi)(chi)→合(he)理電鍍(du)廢蓄水(shui)(shui)池(chi)(chi)；

標準化(hua)管理(li)生活污水→標準化(hua)管理(li)生活污洗手池→快混池→慢混池→斜(xie)管結(jie)晶池→里面池→過濾(lv)水器→pH乖離率指標池→釋放。
