　　工(gong)(gong)業(ye)廢(fei)水(shui)(industrial wastewater)，指工(gong)(gong)藝生(sheng)產(chan)過(guo)程中(zhong)排出(chu)的廢(fei)水(shui)和廢(fei)液，其中(zhong)含有(you)隨水(shui)流失的工(gong)(gong)業(ye)生(sheng)產(chan)用料(liao)、中(zhong)間產(chan)物、副產(chan)品以及生(sheng)產(chan)過(guo)程中(zhong)產(chan)生(sheng)的污染物，是造成環境(jing)污染，特別是水(shui)污染的重要原因。工(gong)(gong)業(ye)廢(fei)水(shui)的處理(li)雖然(ran)早在19世紀末已經開始，但(dan)由(you)于(yu)許(xu)多工(gong)(gong)業(ye)廢(fei)水(shui)成分復(fu)雜，性質多變，仍有(you)一些(xie)技術問(wen)題沒有(you)完全解決。水(shui)處理(li)設備

基本分(fen)類

1、按受(shou)(shou)污(wu)(wu)染程(cheng)(cheng)度(du)(du)不同，工業廢(fei)水(shui)(shui)(shui)可分(fen)為生(sheng)產廢(fei)水(shui)(shui)(shui)及生(sheng)產污(wu)(wu)水(shui)(shui)(shui)兩類。生(sheng)產廢(fei)水(shui)(shui)(shui)是(shi)指在使用過程(cheng)(cheng)中(zhong)受(shou)(shou)到輕度(du)(du)污(wu)(wu)染或(huo)溫度(du)(du)增高的水(shui)(shui)(shui)(如設備冷卻水(shui)(shui)(shui));生(sheng)產污(wu)(wu)水(shui)(shui)(shui)是(shi)指在使用過程(cheng)(cheng)中(zhong)受(shou)(shou)到嚴(yan)重污(wu)(wu)染的水(shui)(shui)(shui)，大多具(ju)有嚴(yan)重的危害性。

2、按工(gong)業廢水(shui)(shui)中所含(han)(han)主要污(wu)(wu)染(ran)物(wu)的(de)化學性(xing)質分(fen)類，可(ke)分(fen)為(wei)含(han)(han)無機(ji)污(wu)(wu)染(ran)物(wu)為(wei)主的(de)無機(ji)廢水(shui)(shui)、含(han)(han)有機(ji)污(wu)(wu)染(ran)物(wu)為(wei)主的(de)有機(ji)廢水(shui)(shui)、兼含(han)(han)有機(ji)物(wu)和無機(ji)物(wu)的(de)混合(he)廢水(shui)(shui)、重(zhong)金屬廢水(shui)(shui)、含(han)(han)放射性(xing)物(wu)質的(de)廢水(shui)(shui)和僅受熱污(wu)(wu)染(ran)的(de)冷(leng)卻(que)水(shui)(shui)。例如電鍍(du)廢水(shui)(shui)和礦物(wu)加工(gong)過(guo)程的(de)廢水(shui)(shui)是無機(ji)廢水(shui)(shui)，食品或石(shi)油加工(gong)過(guo)程的(de)廢水(shui)(shui)是有機(ji)廢水(shui)(shui)。

3、按工(gong)業企業的(de)產品和加工(gong)對象可分為造紙廢(fei)(fei)(fei)水(shui)、紡織(zhi)廢(fei)(fei)(fei)水(shui)、制革(ge)廢(fei)(fei)(fei)水(shui)、農藥廢(fei)(fei)(fei)水(shui)、冶金(jin)廢(fei)(fei)(fei)水(shui)、煉油廢(fei)(fei)(fei)水(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
