　　工(gong)(gong)(gong)業(ye)(ye)廢(fei)(fei)水(shui)(shui)(industrial wastewater)，指(zhi)工(gong)(gong)(gong)藝生產(chan)過(guo)程中(zhong)(zhong)排出的(de)廢(fei)(fei)水(shui)(shui)和廢(fei)(fei)液，其中(zhong)(zhong)含有(you)隨水(shui)(shui)流失(shi)的(de)工(gong)(gong)(gong)業(ye)(ye)生產(chan)用料、中(zhong)(zhong)間產(chan)物(wu)、副產(chan)品以及生產(chan)過(guo)程中(zhong)(zhong)產(chan)生的(de)污(wu)(wu)染(ran)(ran)物(wu)，是造成(cheng)環境污(wu)(wu)染(ran)(ran)，特別(bie)是水(shui)(shui)污(wu)(wu)染(ran)(ran)的(de)重要(yao)原因(yin)。工(gong)(gong)(gong)業(ye)(ye)廢(fei)(fei)水(shui)(shui)的(de)處理(li)雖然早在19世(shi)紀(ji)末已經開始(shi)，但由(you)于(yu)許(xu)多工(gong)(gong)(gong)業(ye)(ye)廢(fei)(fei)水(shui)(shui)成(cheng)分(fen)復雜(za)，性質多變，仍有(you)一些技術問題(ti)沒有(you)完(wan)全(quan)解決。水(shui)(shui)處理(li)設備

基本(ben)分類(lei)

1、按受污(wu)染程(cheng)(cheng)度不同，工業廢(fei)水(shui)可分(fen)為生產廢(fei)水(shui)及生產污(wu)水(shui)兩類。生產廢(fei)水(shui)是(shi)指在使用過(guo)程(cheng)(cheng)中(zhong)受到輕(qing)度污(wu)染或溫度增高的(de)水(shui)(如設備冷卻水(shui));生產污(wu)水(shui)是(shi)指在使用過(guo)程(cheng)(cheng)中(zhong)受到嚴重污(wu)染的(de)水(shui)，大多具(ju)有嚴重的(de)危害性。

2、按工(gong)業廢(fei)(fei)(fei)(fei)水(shui)(shui)中(zhong)所含主(zhu)要(yao)污(wu)染物(wu)(wu)的化學性(xing)質(zhi)分(fen)類，可分(fen)為(wei)(wei)含無(wu)(wu)機污(wu)染物(wu)(wu)為(wei)(wei)主(zhu)的無(wu)(wu)機廢(fei)(fei)(fei)(fei)水(shui)(shui)、含有(you)機污(wu)染物(wu)(wu)為(wei)(wei)主(zhu)的有(you)機廢(fei)(fei)(fei)(fei)水(shui)(shui)、兼含有(you)機物(wu)(wu)和無(wu)(wu)機物(wu)(wu)的混合廢(fei)(fei)(fei)(fei)水(shui)(shui)、重(zhong)金屬廢(fei)(fei)(fei)(fei)水(shui)(shui)、含放射性(xing)物(wu)(wu)質(zhi)的廢(fei)(fei)(fei)(fei)水(shui)(shui)和僅(jin)受熱污(wu)染的冷卻水(shui)(shui)。例如(ru)電鍍廢(fei)(fei)(fei)(fei)水(shui)(shui)和礦(kuang)物(wu)(wu)加工(gong)過程的廢(fei)(fei)(fei)(fei)水(shui)(shui)是無(wu)(wu)機廢(fei)(fei)(fei)(fei)水(shui)(shui)，食品或(huo)石油加工(gong)過程的廢(fei)(fei)(fei)(fei)水(shui)(shui)是有(you)機廢(fei)(fei)(fei)(fei)水(shui)(shui)。

3、按工業企業的產品(pin)和(he)加工對象可分為造(zao)紙(zhi)廢水(shui)(shui)、紡織廢水(shui)(shui)、制革廢水(shui)(shui)、農藥廢水(shui)(shui)、冶金廢水(shui)(shui)、煉油廢水(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
