工業(ye)污水

　　工(gong)(gong)業廢水(shui)(shui)(shui)(shui)(industrial wastewater)，指工(gong)(gong)藝(yi)生(sheng)產過(guo)(guo)程(cheng)中排(pai)出的廢水(shui)(shui)(shui)(shui)和廢液(ye)，其中含有(you)隨水(shui)(shui)(shui)(shui)流失的工(gong)(gong)業生(sheng)產用(yong)料、中間(jian)產物(wu)、副產品以(yi)及生(sheng)產過(guo)(guo)程(cheng)中產生(sheng)的污染物(wu)，是造(zao)成(cheng)環境污染，特別是水(shui)(shui)(shui)(shui)污染的重要原(yuan)因。工(gong)(gong)業廢水(shui)(shui)(shui)(shui)的處理雖然(ran)早(zao)在19世紀末已經(jing)開始，但由于許多工(gong)(gong)業廢水(shui)(shui)(shui)(shui)成(cheng)分復雜(za)，性質多變(bian)，仍有(you)一些技術問(wen)題沒有(you)完全解決。水(shui)(shui)(shui)(shui)處理設備

基本分類

1、按受(shou)污染程(cheng)度不同(tong)，工業廢水(shui)(shui)可(ke)分為生產廢水(shui)(shui)及生產污水(shui)(shui)兩(liang)類。生產廢水(shui)(shui)是(shi)指(zhi)在使用(yong)過程(cheng)中受(shou)到輕(qing)度污染或溫度增高的(de)(de)水(shui)(shui)(如(ru)設備冷(leng)卻水(shui)(shui));生產污水(shui)(shui)是(shi)指(zhi)在使用(yong)過程(cheng)中受(shou)到嚴重污染的(de)(de)水(shui)(shui)，大(da)多具有嚴重的(de)(de)危害性。

2、按(an)工業廢(fei)水(shui)(shui)(shui)中所含(han)(han)主要污染物(wu)(wu)的化(hua)學性質分(fen)類，可分(fen)為(wei)(wei)含(han)(han)無(wu)(wu)(wu)機(ji)污染物(wu)(wu)為(wei)(wei)主的無(wu)(wu)(wu)機(ji)廢(fei)水(shui)(shui)(shui)、含(han)(han)有(you)(you)機(ji)污染物(wu)(wu)為(wei)(wei)主的有(you)(you)機(ji)廢(fei)水(shui)(shui)(shui)、兼含(han)(han)有(you)(you)機(ji)物(wu)(wu)和(he)無(wu)(wu)(wu)機(ji)物(wu)(wu)的混(hun)合廢(fei)水(shui)(shui)(shui)、重金屬(shu)廢(fei)水(shui)(shui)(shui)、含(han)(han)放射性物(wu)(wu)質的廢(fei)水(shui)(shui)(shui)和(he)僅受熱污染的冷(leng)卻水(shui)(shui)(shui)。例如電鍍廢(fei)水(shui)(shui)(shui)和(he)礦物(wu)(wu)加工過(guo)程的廢(fei)水(shui)(shui)(shui)是無(wu)(wu)(wu)機(ji)廢(fei)水(shui)(shui)(shui)，食(shi)品或石油加工過(guo)程的廢(fei)水(shui)(shui)(shui)是有(you)(you)機(ji)廢(fei)水(shui)(shui)(shui)。

3、按工(gong)業企業的產品和加工(gong)對象可分為造紙廢(fei)水、紡織廢(fei)水、制革廢(fei)水、農(nong)藥廢(fei)水、冶金廢(fei)水、煉油廢(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
