生活污水處理工程

生(sheng)(sheng)(sheng)(sheng)(sheng)活(huo)(huo)污(wu)(wu)水(shui)是居民日常生(sheng)(sheng)(sheng)(sheng)(sheng)活(huo)(huo)中(zhong)(zhong)排出的廢(fei)水(shui)，主要來源于(yu)居住(zhu)(zhu)建(jian)筑和(he)公(gong)共建(jian)筑，如住(zhu)(zhu)宅、機(ji)(ji)關、學校、醫院、商店、公(gong)共場所(suo)及(ji)工(gong)業企業衛生(sheng)(sheng)(sheng)(sheng)(sheng)間等(deng)。生(sheng)(sheng)(sheng)(sheng)(sheng)活(huo)(huo)污(wu)(wu)水(shui)所(suo)含的污(wu)(wu)染(ran)(ran)物主要是有(you)機(ji)(ji)物(如蛋白(bai)質、碳水(shui)化(hua)合(he)物、脂(zhi)肪、尿素(su)、氨氮等(deng)) 和(he)大量(liang)病(bing)原(yuan)微生(sheng)(sheng)(sheng)(sheng)(sheng)物(如寄生(sheng)(sheng)(sheng)(sheng)(sheng)蟲(chong)卵和(he)腸道傳染(ran)(ran)病(bing)毒等(deng))。存在于(yu)生(sheng)(sheng)(sheng)(sheng)(sheng)活(huo)(huo)污(wu)(wu)水(shui)中(zhong)(zhong)的有(you)機(ji)(ji)物極不穩定(ding)，容易腐(fu)化(hua)而產生(sheng)(sheng)(sheng)(sheng)(sheng)惡(e)臭(chou)。細(xi)菌和(he)病(bing)原(yuan)體以生(sheng)(sheng)(sheng)(sheng)(sheng)活(huo)(huo)污(wu)(wu)水(shui)中(zhong)(zhong)有(you)機(ji)(ji)物為營(ying)養而大量(liang)繁殖，可導致傳染(ran)(ran)病(bing)蔓(man)延流行。因此，生(sheng)(sheng)(sheng)(sheng)(sheng)活(huo)(huo)污(wu)(wu)水(shui)排放前必須進行處理(li)。
