2、按工(gong)業(ye)廢(fei)(fei)(fei)(fei)水(shui)(shui)(shui)中所含(han)主要污(wu)染(ran)物(wu)的化學(xue)性(xing)質分類，可分為(wei)含(han)無機污(wu)染(ran)物(wu)為(wei)主的無機廢(fei)(fei)(fei)(fei)水(shui)(shui)(shui)、含(han)有機污(wu)染(ran)物(wu)為(wei)主的有機廢(fei)(fei)(fei)(fei)水(shui)(shui)(shui)、兼含(han)有機物(wu)和(he)無機物(wu)的混(hun)合廢(fei)(fei)(fei)(fei)水(shui)(shui)(shui)、重金屬(shu)廢(fei)(fei)(fei)(fei)水(shui)(shui)(shui)、含(han)放射性(xing)物(wu)質的廢(fei)(fei)(fei)(fei)水(shui)(shui)(shui)和(he)僅受熱污(wu)染(ran)的冷卻水(shui)(shui)(shui)。例如電(dian)鍍(du)廢(fei)(fei)(fei)(fei)水(shui)(shui)(shui)和(he)礦(kuang)物(wu)加工(gong)過程(cheng)的廢(fei)(fei)(fei)(fei)水(shui)(shui)(shui)是無機廢(fei)(fei)(fei)(fei)水(shui)(shui)(shui)，食品或石(shi)油加工(gong)過程(cheng)的廢(fei)(fei)(fei)(fei)水(shui)(shui)(shui)是有機廢(fei)(fei)(fei)(fei)水(shui)(shui)(shui)。

3、按工(gong)業企業的產(chan)品和加工(gong)對(dui)象可分為造紙廢(fei)(fei)水(shui)、紡織(zhi)廢(fei)(fei)水(shui)、制革廢(fei)(fei)水(shui)、農藥(yao)廢(fei)(fei)水(shui)、冶(ye)金(jin)廢(fei)(fei)水(shui)、煉(lian)油廢(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
