基本分類(lei)

1、按受污染程度不同，工業廢(fei)(fei)水(shui)可(ke)分(fen)為生(sheng)(sheng)產(chan)廢(fei)(fei)水(shui)及生(sheng)(sheng)產(chan)污水(shui)兩類。生(sheng)(sheng)產(chan)廢(fei)(fei)水(shui)是指在使用(yong)過(guo)(guo)程中受到(dao)輕度污染或溫度增(zeng)高的水(shui)(如設(she)備(bei)冷(leng)卻水(shui));生(sheng)(sheng)產(chan)污水(shui)是指在使用(yong)過(guo)(guo)程中受到(dao)嚴重(zhong)(zhong)污染的水(shui)，大多(duo)具有嚴重(zhong)(zhong)的危害性。

2、按工業(ye)廢(fei)水(shui)中所含主(zhu)要污(wu)(wu)染(ran)物(wu)的化學(xue)性質分(fen)類，可分(fen)為(wei)含無(wu)(wu)(wu)機(ji)污(wu)(wu)染(ran)物(wu)為(wei)主(zhu)的無(wu)(wu)(wu)機(ji)廢(fei)水(shui)、含有機(ji)污(wu)(wu)染(ran)物(wu)為(wei)主(zhu)的有機(ji)廢(fei)水(shui)、兼含有機(ji)物(wu)和無(wu)(wu)(wu)機(ji)物(wu)的混(hun)合廢(fei)水(shui)、重金屬廢(fei)水(shui)、含放(fang)射性物(wu)質的廢(fei)水(shui)和僅受熱污(wu)(wu)染(ran)的冷卻水(shui)。例(li)如(ru)電鍍廢(fei)水(shui)和礦物(wu)加工過程的廢(fei)水(shui)是無(wu)(wu)(wu)機(ji)廢(fei)水(shui)，食品或石油加工過程的廢(fei)水(shui)是有機(ji)廢(fei)水(shui)。

3、按工業企業的產品和加(jia)工對象可分為(wei)造紙廢(fei)(fei)水、紡(fang)織廢(fei)(fei)水、制革廢(fei)(fei)水、農藥廢(fei)(fei)水、冶金廢(fei)(fei)水、煉油廢(fei)(fei)水等。

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
