工(gong)業污水

　　工(gong)(gong)業(ye)(ye)(ye)(ye)廢水(shui)(shui)(shui)(industrial wastewater)，指工(gong)(gong)藝生(sheng)(sheng)(sheng)產過程(cheng)中(zhong)(zhong)排出的廢水(shui)(shui)(shui)和廢液，其中(zhong)(zhong)含有隨(sui)水(shui)(shui)(shui)流失的工(gong)(gong)業(ye)(ye)(ye)(ye)生(sheng)(sheng)(sheng)產用料、中(zhong)(zhong)間產物、副產品以及(ji)生(sheng)(sheng)(sheng)產過程(cheng)中(zhong)(zhong)產生(sheng)(sheng)(sheng)的污(wu)染(ran)物，是造成環境污(wu)染(ran)，特別是水(shui)(shui)(shui)污(wu)染(ran)的重(zhong)要原因。工(gong)(gong)業(ye)(ye)(ye)(ye)廢水(shui)(shui)(shui)的處理(li)雖然早在19世紀(ji)末(mo)已(yi)經開始，但由于許多工(gong)(gong)業(ye)(ye)(ye)(ye)廢水(shui)(shui)(shui)成分復雜，性(xing)質多變，仍(reng)有一些(xie)技術問題沒有完全解決。水(shui)(shui)(shui)處理(li)設備

基本分(fen)類

1、按(an)受(shou)(shou)污(wu)染程度(du)不(bu)同，工業(ye)廢水(shui)(shui)可(ke)分為生(sheng)(sheng)產廢水(shui)(shui)及生(sheng)(sheng)產污(wu)水(shui)(shui)兩類。生(sheng)(sheng)產廢水(shui)(shui)是指(zhi)在使(shi)用過程中受(shou)(shou)到(dao)輕(qing)度(du)污(wu)染或溫度(du)增高的水(shui)(shui)(如設備冷(leng)卻(que)水(shui)(shui));生(sheng)(sheng)產污(wu)水(shui)(shui)是指(zhi)在使(shi)用過程中受(shou)(shou)到(dao)嚴(yan)重污(wu)染的水(shui)(shui)，大多具有嚴(yan)重的危害(hai)性。

2、按工業(ye)廢水(shui)(shui)(shui)(shui)中所含(han)主(zhu)要污(wu)染物(wu)的(de)化學(xue)性質分(fen)類，可分(fen)為(wei)含(han)無(wu)機(ji)污(wu)染物(wu)為(wei)主(zhu)的(de)無(wu)機(ji)廢水(shui)(shui)(shui)(shui)、含(han)有(you)機(ji)污(wu)染物(wu)為(wei)主(zhu)的(de)有(you)機(ji)廢水(shui)(shui)(shui)(shui)、兼含(han)有(you)機(ji)物(wu)和無(wu)機(ji)物(wu)的(de)混合廢水(shui)(shui)(shui)(shui)、重金屬(shu)廢水(shui)(shui)(shui)(shui)、含(han)放射性物(wu)質的(de)廢水(shui)(shui)(shui)(shui)和僅受熱污(wu)染的(de)冷(leng)卻水(shui)(shui)(shui)(shui)。例如(ru)電鍍廢水(shui)(shui)(shui)(shui)和礦物(wu)加(jia)工過(guo)程的(de)廢水(shui)(shui)(shui)(shui)是無(wu)機(ji)廢水(shui)(shui)(shui)(shui)，食品或石(shi)油(you)加(jia)工過(guo)程的(de)廢水(shui)(shui)(shui)(shui)是有(you)機(ji)廢水(shui)(shui)(shui)(shui)。

3、按工業(ye)(ye)企業(ye)(ye)的產品(pin)和(he)加工對(dui)象可分為(wei)造紙廢(fei)水(shui)(shui)(shui)、紡織廢(fei)水(shui)(shui)(shui)、制(zhi)革廢(fei)水(shui)(shui)(shui)、農藥(yao)廢(fei)水(shui)(shui)(shui)、冶(ye)金廢(fei)水(shui)(shui)(shui)、煉油廢(fei)水(shui)(shui)(shui)等。

4、按廢水中所含污染物的主要成分可分為酸性廢水、堿性廢水、含酚廢水、含鉻廢水、含有機磷廢水和放射性廢水等。新疆污水處理設備
