工(gong)業污水

　　工(gong)業(ye)(ye)廢(fei)(fei)水(shui)(shui)(industrial wastewater)，指工(gong)藝生(sheng)(sheng)產(chan)(chan)過(guo)程中(zhong)排出(chu)的(de)廢(fei)(fei)水(shui)(shui)和廢(fei)(fei)液，其中(zhong)含有(you)隨(sui)水(shui)(shui)流失的(de)工(gong)業(ye)(ye)生(sheng)(sheng)產(chan)(chan)用(yong)料(liao)、中(zhong)間(jian)產(chan)(chan)物、副產(chan)(chan)品以(yi)及生(sheng)(sheng)產(chan)(chan)過(guo)程中(zhong)產(chan)(chan)生(sheng)(sheng)的(de)污(wu)染物，是(shi)造成環境污(wu)染，特別(bie)是(shi)水(shui)(shui)污(wu)染的(de)重要(yao)原(yuan)因。工(gong)業(ye)(ye)廢(fei)(fei)水(shui)(shui)的(de)處理雖(sui)然早(zao)在19世紀(ji)末已經開始，但由于許(xu)多工(gong)業(ye)(ye)廢(fei)(fei)水(shui)(shui)成分復(fu)雜，性質多變，仍有(you)一些技術問題沒有(you)完(wan)全解決。水(shui)(shui)處理設備(bei)

基本分(fen)類

1、按受(shou)(shou)污(wu)(wu)(wu)染(ran)程度(du)不同，工業廢水(shui)(shui)(shui)可分為生(sheng)產(chan)廢水(shui)(shui)(shui)及生(sheng)產(chan)污(wu)(wu)(wu)水(shui)(shui)(shui)兩類。生(sheng)產(chan)廢水(shui)(shui)(shui)是(shi)指在(zai)使(shi)用過(guo)程中受(shou)(shou)到(dao)輕(qing)度(du)污(wu)(wu)(wu)染(ran)或(huo)溫度(du)增高(gao)的(de)(de)水(shui)(shui)(shui)(如(ru)設備(bei)冷卻水(shui)(shui)(shui));生(sheng)產(chan)污(wu)(wu)(wu)水(shui)(shui)(shui)是(shi)指在(zai)使(shi)用過(guo)程中受(shou)(shou)到(dao)嚴重污(wu)(wu)(wu)染(ran)的(de)(de)水(shui)(shui)(shui)，大多具有(you)嚴重的(de)(de)危(wei)害(hai)性。

2、按工(gong)(gong)業(ye)廢(fei)(fei)水(shui)(shui)(shui)(shui)(shui)中所含(han)(han)主(zhu)要污染(ran)物的化學性(xing)質分類，可分為含(han)(han)無(wu)(wu)(wu)機(ji)污染(ran)物為主(zhu)的無(wu)(wu)(wu)機(ji)廢(fei)(fei)水(shui)(shui)(shui)(shui)(shui)、含(han)(han)有(you)機(ji)污染(ran)物為主(zhu)的有(you)機(ji)廢(fei)(fei)水(shui)(shui)(shui)(shui)(shui)、兼含(han)(han)有(you)機(ji)物和(he)(he)無(wu)(wu)(wu)機(ji)物的混合廢(fei)(fei)水(shui)(shui)(shui)(shui)(shui)、重金屬廢(fei)(fei)水(shui)(shui)(shui)(shui)(shui)、含(han)(han)放射性(xing)物質的廢(fei)(fei)水(shui)(shui)(shui)(shui)(shui)和(he)(he)僅受熱污染(ran)的冷(leng)卻水(shui)(shui)(shui)(shui)(shui)。例如(ru)電鍍(du)廢(fei)(fei)水(shui)(shui)(shui)(shui)(shui)和(he)(he)礦(kuang)物加工(gong)(gong)過程(cheng)(cheng)的廢(fei)(fei)水(shui)(shui)(shui)(shui)(shui)是(shi)無(wu)(wu)(wu)機(ji)廢(fei)(fei)水(shui)(shui)(shui)(shui)(shui)，食品或(huo)石(shi)油加工(gong)(gong)過程(cheng)(cheng)的廢(fei)(fei)水(shui)(shui)(shui)(shui)(shui)是(shi)有(you)機(ji)廢(fei)(fei)水(shui)(shui)(shui)(shui)(shui)。

3、按(an)工(gong)業企業的產品和(he)加工(gong)對象(xiang)可(ke)分為造紙廢水、紡(fang)織廢水、制(zhi)革廢水、農(nong)藥廢水、冶金廢水、煉油廢水等。

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
