       含油(you)(you)废水(shui)主要来源于石(shi)油(you)(you)、石(shi)油(you)(you)化工、钢铁、焦化、煤气发生(sheng)站(zhan)、机械加(jia)工等工业部门(men)。废水(shui)中油(you)(you)类污染物质，除(chu)重焦油(you)(you)的(de)相对密度为(wei)1．1以上(shang)外，其余的(de)相对密度都小(xiao)于1。

　　含油(you)(you)(you)(you)废(fei)(fei)(fei)(fei)水(shui)(shui)(shui)(shui)中(zhong)(zhong)(zhong)所含的(de)油(you)(you)(you)(you)类物(wu)质，包括天然(ran)石油(you)(you)(you)(you)、石油(you)(you)(you)(you)产(chan)(chan)品、焦(jiao)油(you)(you)(you)(you)及其分馏物(wu)，以及食用(yong)动植物(wu)油(you)(you)(you)(you)和(he)(he)脂肪(fang)类。从(cong)对水(shui)(shui)(shui)(shui)体的(de)污染来说，主要(yao)是(shi)石油(you)(you)(you)(you)和(he)(he)焦(jiao)油(you)(you)(you)(you)。由于不同工业(ye)部门排出(chu)的(de)废(fei)(fei)(fei)(fei)水(shui)(shui)(shui)(shui)中(zhong)(zhong)(zhong)含油(you)(you)(you)(you)浓度差异很大，如炼油(you)(you)(you)(you)过程中(zhong)(zhong)(zhong)产(chan)(chan)生废(fei)(fei)(fei)(fei)水(shui)(shui)(shui)(shui)，含油(you)(you)(you)(you)量约(yue)为150一(yi)1000mg/L，焦(jiao)化(hua)废(fei)(fei)(fei)(fei)水(shui)(shui)(shui)(shui)中(zhong)(zhong)(zhong)焦(jiao)油(you)(you)(you)(you)含量约(yue)为500一(yi)800mg/L，煤气发(fa)生站排出(chu)废(fei)(fei)(fei)(fei)水(shui)(shui)(shui)(shui)中(zhong)(zhong)(zhong)的(de)焦(jiao)油(you)(you)(you)(you)含量可达2000一(yi)3000mg/L。因(yin)此，含油(you)(you)(you)(you)废(fei)(fei)(fei)(fei)水(shui)(shui)(shui)(shui)的(de)治理(li)应(ying)首(shou)先利用(yong)隔油(you)(you)(you)(you)池(chi)，回收(shou)浮油(you)(you)(you)(you)或重(zhong)油(you)(you)(you)(you)，处(chu)理(li)效(xiao)率为60%一(yi)80%，出(chu)水(shui)(shui)(shui)(shui)中(zhong)(zhong)(zhong)含油(you)(you)(you)(you)量约(yue)为100一(yi)200mg/L；废(fei)(fei)(fei)(fei)水(shui)(shui)(shui)(shui)中(zhong)(zhong)(zhong)的(de)乳化(hua)油(you)(you)(you)(you)和(he)(he)分散油(you)(you)(you)(you)较难处(chu)理(li)，故应(ying)防止或减(jian)轻乳化(hua)现象。方法之*，是(shi)在(zai)生产(chan)(chan)过程中(zhong)(zhong)(zhong)注(zhu)意减(jian)轻废(fei)(fei)(fei)(fei)水(shui)(shui)(shui)(shui)中(zhong)(zhong)(zhong)油(you)(you)(you)(you)的(de)乳化(hua)；其二，是(shi)在(zai)处(chu)理(li)过程中(zhong)(zhong)(zhong)，尽量减(jian)少用(yong)泵提升废(fei)(fei)(fei)(fei)水(shui)(shui)(shui)(shui)的(de)次数、以免增加乳化(hua)程度。处(chu)理(li)方法通常(chang)采用(yong)气浮法和(he)(he)破乳法。

　　含(han)油(you)废水如果(guo)不加以回收处(chu)理(li)，会(hui)造成浪(lang)费；排入河流(liu)、湖(hu)泊或海湾(wan),会(hui)污染水体,影响水生生物(wu)生存；用于农业灌溉，则会(hui)堵塞土(tu)壤空隙，妨碍(ai)农作(zuo)物(wu)生长。

　　含(han)油(you)(you)废水(shui)的处理(li)应首先(xian)考虑回(hui)收油(you)(you)类物(wu)质，并充分(fen)利用(yong)(yong)经过处理(li)的水(shui)资源。因(yin)此，含(han)油(you)(you)废水(shui)的处理(li)可(ke)首先(xian)利用(yong)(yong)隔油(you)(you)池(chi)，回(hui)收浮油(you)(you)或重油(you)(you)。隔油(you)(you)池(chi)适(shi)用(yong)(yong)于分(fen)离废水(shui)中(zhong)颗粒较大的油(you)(you)品(pin)，处理(li)效率为60～80%，出(chu)水(shui)中(zhong)含(han)油(you)(you)量约为100～200毫克/升(sheng)。
