電(dian)鍍(du)(du)是一(yi)種(zhong)借助電(dian)流的(de)(de)(de)作用，將有(you)關金屬均勻涂(tu)覆到基底材料表(biao)(biao)面(mian)的(de)(de)(de)過程。作為(wei)一(yi)種(zhong)表(biao)(biao)面(mian)精湛的(de)(de)(de)工(gong)(gong)藝，電(dian)鍍(du)(du)已成(cheng)為(wei)機械、電(dian)子、儀器、儀表(biao)(biao)、輕工(gong)(gong)、航天等(deng)諸多領(ling)域中提(ti)(ti)升產(chan)品(pin)質量(liang)檔次的(de)(de)(de)一(yi)種(zhong)必不可少的(de)(de)(de)重要(yao)手段。它伴隨著(zhu)被鍍(du)(du)產(chan)品(pin)的(de)(de)(de)發(fa)展而發(fa)展，同(tong)時又對被鍍(du)(du)產(chan)品(pin)質量(liang)的(de)(de)(de)提(ti)(ti)高起著(zhu)重要(yao)作用，其特(te)有(you)的(de)(de)(de)裝飾(shi)性、防護性及多功能(neng)賦予了被鍍(du)(du)產(chan)品(pin)多種(zhong)新的(de)(de)(de)功能(neng)，能(neng)夠更好(hao)地滿足工(gong)(gong)業(ye)(ye)和人們日常生(sheng)活的(de)(de)(de)需要(yao)，是被鍍(du)(du)產(chan)品(pin)在激烈(lie)競(jing)爭(zheng)中占領(ling)市場(chang)的(de)(de)(de)重要(yao)支撐。電(dian)鍍(du)(du)工(gong)(gong)業(ye)(ye)已經(jing)成(cheng)為(wei)我國(guo)重要(yao)的(de)(de)(de)加工(gong)(gong)行業(ye)(ye)之一(yi)，在國(guo)民經(jing)濟中占有(you)舉足輕重的(de)(de)(de)地位(wei)。

據粗(cu)略統計(ji)，全國現有電(dian)(dian)(dian)鍍(du)(du)(du)(du)(du)生(sheng)產(chan)企(qi)(qi)業(ye)(ye)約15000多(duo)(duo)家，與電(dian)(dian)(dian)鍍(du)(du)(du)(du)(du)生(sheng)產(chan)企(qi)(qi)業(ye)(ye)配套(tao)的(de)企(qi)(qi)業(ye)(ye)數(shu)百家，形成了5000多(duo)(duo)條不同規(gui)模的(de)生(sheng)產(chan)線(xian)，年(nian)生(sheng)產(chan)能力達到3×109㎡以上的(de)電(dian)(dian)(dian)鍍(du)(du)(du)(du)(du)面積。近十年(nian)來，民營電(dian)(dian)(dian)鍍(du)(du)(du)(du)(du)企(qi)(qi)業(ye)(ye)發展(zhan)迅速，但企(qi)(qi)業(ye)(ye)規(gui)模普遍較小，年(nian)電(dian)(dian)(dian)鍍(du)(du)(du)(du)(du)能力超過105㎡的(de)企(qi)(qi)業(ye)(ye)不足500家，大(da)多(duo)(duo)數(shu)企(qi)(qi)業(ye)(ye)使用(yong)的(de)技(ji)術和設備較為陳(chen)舊(jiu)，生(sheng)產(chan)線(xian)一(yi)般為半機(ji)械化(hua)和半自(zi)動化(hua)控制，少數(shu)仍(reng)然是手工(gong)(gong)操(cao)作。從(cong)行業(ye)(ye)分(fen)布(bu)上講，電(dian)(dian)(dian)鍍(du)(du)(du)(du)(du)企(qi)(qi)業(ye)(ye)中約有33.8%分(fen)布(bu)在(zai)(zai)機(ji)器制造工(gong)(gong)業(ye)(ye)，20.2%在(zai)(zai)輕工(gong)(gong)業(ye)(ye)，5-10%在(zai)(zai)電(dian)(dian)(dian)子(zi)工(gong)(gong)業(ye)(ye)，其(qi)余主要分(fen)布(bu)在(zai)(zai)航空、航天及(ji)儀(yi)器、儀(yi)表工(gong)(gong)業(ye)(ye)。從(cong)電(dian)(dian)(dian)鍍(du)(du)(du)(du)(du)品種(zhong)上講，我國電(dian)(dian)(dian)鍍(du)(du)(du)(du)(du)加工(gong)(gong)中涉及(ji)最廣的(de)是電(dian)(dian)(dian)鍍(du)(du)(du)(du)(du)鋅、銅(tong)、鎳(nie)和鉻，其(qi)中鍍(du)(du)(du)(du)(du)鋅占(zhan)45-50%，鍍(du)(du)(du)(du)(du)銅(tong)鎳(nie)鉻占(zhan)30%，氧化(hua)鋁和陽極化(hua)膜(mo)占(zhan)15%，電(dian)(dian)(dian)子(zi)產(chan)品鍍(du)(du)(du)(du)(du)鉛、錫和金(jin)銀等貴重金(jin)屬約占(zhan)5%。

電(dian)鍍(du)(du)行業(ye)是全(quan)球三(san)大污染(ran)工業(ye)之一。我國(guo)電(dian)鍍(du)(du)行業(ye)目前迅速發(fa)展，同時帶來(lai)的(de)(de)電(dian)鍍(du)(du)廢(fei)(fei)(fei)(fei)水(shui)(shui)(shui)(shui)(shui)(shui)對環(huan)境污染(ran)的(de)(de)問題相當嚴重(zhong)，全(quan)國(guo)電(dian)鍍(du)(du)行業(ye)每年生(sheng)(sheng)產廢(fei)(fei)(fei)(fei)水(shui)(shui)(shui)(shui)(shui)(shui)大約有40億噸(dun)，嚴重(zhong)加劇水(shui)(shui)(shui)(shui)(shui)(shui)資(zi)源(yuan)短缺，制約電(dian)鍍(du)(du)行業(ye)在我國(guo)的(de)(de)可持(chi)續(xu)發(fa)展。對電(dian)鍍(du)(du)行業(ye)實行清潔生(sheng)(sheng)產，改(gai)變鍍(du)(du)液組成部分，清洗方法及(ji)設備改(gai)造以減少廢(fei)(fei)(fei)(fei)水(shui)(shui)(shui)(shui)(shui)(shui)排放量和(he)污染(ran)物濃度。電(dian)鍍(du)(du)廢(fei)(fei)(fei)(fei)水(shui)(shui)(shui)(shui)(shui)(shui)主要包括(kuo)酸堿除油(you)廢(fei)(fei)(fei)(fei)水(shui)(shui)(shui)(shui)(shui)(shui)、鍍(du)(du)件(jian)漂洗水(shui)(shui)(shui)(shui)(shui)(shui)，廢(fei)(fei)(fei)(fei)槽液，冷卻水(shui)(shui)(shui)(shui)(shui)(shui)等，一般(ban)分為含氰(qing)廢(fei)(fei)(fei)(fei)水(shui)(shui)(shui)(shui)(shui)(shui)，廢(fei)(fei)(fei)(fei)水(shui)(shui)(shui)(shui)(shui)(shui)(20—70mg/L)，重(zhong)金屬廢(fei)(fei)(fei)(fei)水(shui)(shui)(shui)(shui)(shui)(shui)(20—100 mg/L)，酸堿等三(san)種廢(fei)(fei)(fei)(fei)水(shui)(shui)(shui)(shui)(shui)(shui)系統。廢(fei)(fei)(fei)(fei)水(shui)(shui)(shui)(shui)(shui)(shui)流(liu)量隨生(sheng)(sheng)產規模和(he)生(sheng)(sheng)產工藝而異。
