2、按工(gong)(gong)業廢(fei)水(shui)(shui)(shui)(shui)(shui)中所含(han)主(zhu)(zhu)要污(wu)(wu)染物的(de)化學(xue)性質(zhi)分(fen)類，可(ke)分(fen)為含(han)無(wu)機(ji)(ji)污(wu)(wu)染物為主(zhu)(zhu)的(de)無(wu)機(ji)(ji)廢(fei)水(shui)(shui)(shui)(shui)(shui)、含(han)有機(ji)(ji)污(wu)(wu)染物為主(zhu)(zhu)的(de)有機(ji)(ji)廢(fei)水(shui)(shui)(shui)(shui)(shui)、兼含(han)有機(ji)(ji)物和(he)無(wu)機(ji)(ji)物的(de)混(hun)合廢(fei)水(shui)(shui)(shui)(shui)(shui)、重金屬廢(fei)水(shui)(shui)(shui)(shui)(shui)、含(han)放射性物質(zhi)的(de)廢(fei)水(shui)(shui)(shui)(shui)(shui)和(he)僅受熱污(wu)(wu)染的(de)冷(leng)卻水(shui)(shui)(shui)(shui)(shui)。例如電鍍廢(fei)水(shui)(shui)(shui)(shui)(shui)和(he)礦物加工(gong)(gong)過程的(de)廢(fei)水(shui)(shui)(shui)(shui)(shui)是無(wu)機(ji)(ji)廢(fei)水(shui)(shui)(shui)(shui)(shui)，食品或石油(you)加工(gong)(gong)過程的(de)廢(fei)水(shui)(shui)(shui)(shui)(shui)是有機(ji)(ji)廢(fei)水(shui)(shui)(shui)(shui)(shui)。

3、按(an)工(gong)業企業的(de)產品和加工(gong)對(dui)象可分為造紙廢(fei)水(shui)、紡織廢(fei)水(shui)、制革廢(fei)水(shui)、農藥廢(fei)水(shui)、冶金(jin)廢(fei)水(shui)、煉油廢(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
