工業污水

　　工(gong)業(ye)廢水(shui)(industrial wastewater)，指工(gong)藝生(sheng)產過程中(zhong)(zhong)(zhong)排出的(de)(de)廢水(shui)和廢液，其中(zhong)(zhong)(zhong)含有隨水(shui)流失(shi)的(de)(de)工(gong)業(ye)生(sheng)產用料(liao)、中(zhong)(zhong)(zhong)間產物、副產品以及生(sheng)產過程中(zhong)(zhong)(zhong)產生(sheng)的(de)(de)污(wu)染物，是造成(cheng)(cheng)環境污(wu)染，特別是水(shui)污(wu)染的(de)(de)重要(yao)原(yuan)因。工(gong)業(ye)廢水(shui)的(de)(de)處理(li)雖然早在19世紀末已經開(kai)始，但(dan)由于許多工(gong)業(ye)廢水(shui)成(cheng)(cheng)分(fen)復雜，性質多變(bian)，仍有一(yi)些技術(shu)問題(ti)沒有完全解(jie)決。水(shui)處理(li)設(she)備(bei)

基本分(fen)類

1、按受(shou)污(wu)染(ran)(ran)(ran)程度不同，工業(ye)廢(fei)水(shui)(shui)(shui)可分為生產(chan)廢(fei)水(shui)(shui)(shui)及生產(chan)污(wu)水(shui)(shui)(shui)兩類。生產(chan)廢(fei)水(shui)(shui)(shui)是(shi)指在(zai)使用(yong)過(guo)程中(zhong)(zhong)受(shou)到輕(qing)度污(wu)染(ran)(ran)(ran)或溫度增(zeng)高的水(shui)(shui)(shui)(如設備(bei)冷卻水(shui)(shui)(shui));生產(chan)污(wu)水(shui)(shui)(shui)是(shi)指在(zai)使用(yong)過(guo)程中(zhong)(zhong)受(shou)到嚴重(zhong)污(wu)染(ran)(ran)(ran)的水(shui)(shui)(shui)，大多(duo)具有(you)嚴重(zhong)的危(wei)害性。

2、按工業(ye)廢(fei)(fei)水(shui)(shui)中所含(han)主要污染物(wu)的化學性質(zhi)分(fen)類(lei)，可分(fen)為(wei)含(han)無(wu)(wu)(wu)機污染物(wu)為(wei)主的無(wu)(wu)(wu)機廢(fei)(fei)水(shui)(shui)、含(han)有機污染物(wu)為(wei)主的有機廢(fei)(fei)水(shui)(shui)、兼含(han)有機物(wu)和無(wu)(wu)(wu)機物(wu)的混(hun)合廢(fei)(fei)水(shui)(shui)、重金屬廢(fei)(fei)水(shui)(shui)、含(han)放射(she)性物(wu)質(zhi)的廢(fei)(fei)水(shui)(shui)和僅受熱污染的冷卻水(shui)(shui)。例如電鍍廢(fei)(fei)水(shui)(shui)和礦(kuang)物(wu)加工過(guo)程(cheng)的廢(fei)(fei)水(shui)(shui)是無(wu)(wu)(wu)機廢(fei)(fei)水(shui)(shui)，食品或石油加工過(guo)程(cheng)的廢(fei)(fei)水(shui)(shui)是有機廢(fei)(fei)水(shui)(shui)。

3、按工(gong)業(ye)企業(ye)的產品和加工(gong)對象可分(fen)為造紙廢(fei)(fei)水(shui)、紡織廢(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)、煉油廢(fei)(fei)水(shui)等(deng)。

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
