生活污水處理工程

生(sheng)(sheng)(sheng)(sheng)活(huo)(huo)(huo)污(wu)水(shui)(shui)(shui)是(shi)(shi)居(ju)(ju)民日常生(sheng)(sheng)(sheng)(sheng)活(huo)(huo)(huo)中(zhong)排出的廢水(shui)(shui)(shui)，主要來源于(yu)居(ju)(ju)住(zhu)建筑(zhu)和(he)(he)公共(gong)建筑(zhu)，如住(zhu)宅、機(ji)(ji)關、學(xue)校、醫院、商店、公共(gong)場所及工(gong)業企業衛生(sheng)(sheng)(sheng)(sheng)間等(deng)。生(sheng)(sheng)(sheng)(sheng)活(huo)(huo)(huo)污(wu)水(shui)(shui)(shui)所含的污(wu)染物(wu)(wu)(wu)主要是(shi)(shi)有(you)機(ji)(ji)物(wu)(wu)(wu)(如蛋白質、碳(tan)水(shui)(shui)(shui)化合物(wu)(wu)(wu)、脂肪、尿素、氨氮等(deng)) 和(he)(he)大(da)量病原(yuan)微生(sheng)(sheng)(sheng)(sheng)物(wu)(wu)(wu)(如寄生(sheng)(sheng)(sheng)(sheng)蟲卵和(he)(he)腸道傳染病毒(du)等(deng))。存在(zai)于(yu)生(sheng)(sheng)(sheng)(sheng)活(huo)(huo)(huo)污(wu)水(shui)(shui)(shui)中(zhong)的有(you)機(ji)(ji)物(wu)(wu)(wu)極不穩定，容易腐化而產生(sheng)(sheng)(sheng)(sheng)惡臭(chou)。細菌和(he)(he)病原(yuan)體以生(sheng)(sheng)(sheng)(sheng)活(huo)(huo)(huo)污(wu)水(shui)(shui)(shui)中(zhong)有(you)機(ji)(ji)物(wu)(wu)(wu)為營養(yang)而大(da)量繁殖(zhi)，可(ke)導致傳染病蔓延(yan)流行。因此，生(sheng)(sheng)(sheng)(sheng)活(huo)(huo)(huo)污(wu)水(shui)(shui)(shui)排放前必須進行處理。
