工(gong)業污水

　　工(gong)(gong)(gong)業廢(fei)(fei)水(shui)(shui)(industrial wastewater)，指工(gong)(gong)(gong)藝生(sheng)(sheng)產(chan)過程中(zhong)(zhong)(zhong)(zhong)排出(chu)的(de)廢(fei)(fei)水(shui)(shui)和(he)廢(fei)(fei)液，其中(zhong)(zhong)(zhong)(zhong)含有隨(sui)水(shui)(shui)流失的(de)工(gong)(gong)(gong)業生(sheng)(sheng)產(chan)用料、中(zhong)(zhong)(zhong)(zhong)間產(chan)物、副(fu)產(chan)品以及生(sheng)(sheng)產(chan)過程中(zhong)(zhong)(zhong)(zhong)產(chan)生(sheng)(sheng)的(de)污(wu)染物，是造成環境污(wu)染，特別是水(shui)(shui)污(wu)染的(de)重要原因。工(gong)(gong)(gong)業廢(fei)(fei)水(shui)(shui)的(de)處理雖(sui)然早在19世紀(ji)末已(yi)經開始(shi)，但由于(yu)許(xu)多工(gong)(gong)(gong)業廢(fei)(fei)水(shui)(shui)成分復雜，性質多變，仍有一些(xie)技術問題沒有完全解決。水(shui)(shui)處理設(she)備

基本分類

1、按受污(wu)染程(cheng)度(du)不(bu)同，工業廢水(shui)可(ke)分(fen)為生(sheng)產(chan)廢水(shui)及(ji)生(sheng)產(chan)污(wu)水(shui)兩類。生(sheng)產(chan)廢水(shui)是指在(zai)使(shi)用過(guo)程(cheng)中(zhong)受到輕度(du)污(wu)染或溫度(du)增高(gao)的水(shui)(如設備冷(leng)卻(que)水(shui));生(sheng)產(chan)污(wu)水(shui)是指在(zai)使(shi)用過(guo)程(cheng)中(zhong)受到嚴重污(wu)染的水(shui)，大多具(ju)有嚴重的危害性。

2、按工(gong)(gong)業廢(fei)水(shui)(shui)(shui)中所含(han)(han)(han)主(zhu)(zhu)要污(wu)染(ran)物(wu)(wu)的(de)化學性質分類，可分為(wei)含(han)(han)(han)無機(ji)(ji)污(wu)染(ran)物(wu)(wu)為(wei)主(zhu)(zhu)的(de)無機(ji)(ji)廢(fei)水(shui)(shui)(shui)、含(han)(han)(han)有機(ji)(ji)污(wu)染(ran)物(wu)(wu)為(wei)主(zhu)(zhu)的(de)有機(ji)(ji)廢(fei)水(shui)(shui)(shui)、兼含(han)(han)(han)有機(ji)(ji)物(wu)(wu)和(he)無機(ji)(ji)物(wu)(wu)的(de)混(hun)合廢(fei)水(shui)(shui)(shui)、重金屬(shu)廢(fei)水(shui)(shui)(shui)、含(han)(han)(han)放射性物(wu)(wu)質的(de)廢(fei)水(shui)(shui)(shui)和(he)僅受熱污(wu)染(ran)的(de)冷(leng)卻水(shui)(shui)(shui)。例(li)如電鍍(du)廢(fei)水(shui)(shui)(shui)和(he)礦(kuang)物(wu)(wu)加(jia)工(gong)(gong)過(guo)(guo)程(cheng)的(de)廢(fei)水(shui)(shui)(shui)是(shi)無機(ji)(ji)廢(fei)水(shui)(shui)(shui)，食品(pin)或石油加(jia)工(gong)(gong)過(guo)(guo)程(cheng)的(de)廢(fei)水(shui)(shui)(shui)是(shi)有機(ji)(ji)廢(fei)水(shui)(shui)(shui)。

3、按工業(ye)企業(ye)的產品和加工對象可(ke)分為(wei)造紙(zhi)廢(fei)(fei)水、紡(fang)織廢(fei)(fei)水、制(zhi)革廢(fei)(fei)水、農藥廢(fei)(fei)水、冶(ye)金廢(fei)(fei)水、煉油廢(fei)(fei)水等(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
