　　工業廢(fei)(fei)水(shui)(industrial wastewater)，指工藝生(sheng)產過程中(zhong)(zhong)排出的廢(fei)(fei)水(shui)和(he)廢(fei)(fei)液，其中(zhong)(zhong)含有隨水(shui)流(liu)失(shi)的工業生(sheng)產用料、中(zhong)(zhong)間產物、副產品以及生(sheng)產過程中(zhong)(zhong)產生(sheng)的污染(ran)物，是造(zao)成(cheng)環(huan)境污染(ran)，特(te)別是水(shui)污染(ran)的重要(yao)原因(yin)。工業廢(fei)(fei)水(shui)的處(chu)理雖然(ran)早(zao)在19世紀末(mo)已經開始，但(dan)由于許多工業廢(fei)(fei)水(shui)成(cheng)分復雜(za)，性質多變，仍(reng)有一些技(ji)術(shu)問題(ti)沒有完全解決。水(shui)處(chu)理設備

基本分類(lei)

1、按(an)受(shou)污(wu)染程(cheng)度不同，工業廢(fei)水(shui)(shui)可(ke)分(fen)為生產(chan)廢(fei)水(shui)(shui)及生產(chan)污(wu)水(shui)(shui)兩(liang)類。生產(chan)廢(fei)水(shui)(shui)是(shi)指在使(shi)用(yong)(yong)過程(cheng)中受(shou)到輕度污(wu)染或(huo)溫度增(zeng)高的水(shui)(shui)(如設備冷卻水(shui)(shui));生產(chan)污(wu)水(shui)(shui)是(shi)指在使(shi)用(yong)(yong)過程(cheng)中受(shou)到嚴(yan)重(zhong)污(wu)染的水(shui)(shui)，大多具有嚴(yan)重(zhong)的危害性。

2、按工(gong)業廢(fei)(fei)水(shui)(shui)(shui)中所(suo)含(han)主要污(wu)染(ran)物(wu)(wu)(wu)的化(hua)學性(xing)質分類，可分為含(han)無(wu)(wu)機(ji)(ji)污(wu)染(ran)物(wu)(wu)(wu)為主的無(wu)(wu)機(ji)(ji)廢(fei)(fei)水(shui)(shui)(shui)、含(han)有(you)機(ji)(ji)污(wu)染(ran)物(wu)(wu)(wu)為主的有(you)機(ji)(ji)廢(fei)(fei)水(shui)(shui)(shui)、兼(jian)含(han)有(you)機(ji)(ji)物(wu)(wu)(wu)和無(wu)(wu)機(ji)(ji)物(wu)(wu)(wu)的混合廢(fei)(fei)水(shui)(shui)(shui)、重(zhong)金屬廢(fei)(fei)水(shui)(shui)(shui)、含(han)放射性(xing)物(wu)(wu)(wu)質的廢(fei)(fei)水(shui)(shui)(shui)和僅受熱污(wu)染(ran)的冷卻(que)水(shui)(shui)(shui)。例如電鍍(du)廢(fei)(fei)水(shui)(shui)(shui)和礦物(wu)(wu)(wu)加(jia)工(gong)過程的廢(fei)(fei)水(shui)(shui)(shui)是無(wu)(wu)機(ji)(ji)廢(fei)(fei)水(shui)(shui)(shui)，食品或石(shi)油加(jia)工(gong)過程的廢(fei)(fei)水(shui)(shui)(shui)是有(you)機(ji)(ji)廢(fei)(fei)水(shui)(shui)(shui)。

3、按工業企業的產品和加工對象可分為造紙廢(fei)(fei)水(shui)(shui)、紡織廢(fei)(fei)水(shui)(shui)、制革廢(fei)(fei)水(shui)(shui)、農藥(yao)廢(fei)(fei)水(shui)(shui)、冶金廢(fei)(fei)水(shui)(shui)、煉(lian)油廢(fei)(fei)水(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
