生(sheng)(sheng)(sheng)活(huo)(huo)污(wu)(wu)水(shui)(shui)是居民日常生(sheng)(sheng)(sheng)活(huo)(huo)中(zhong)排(pai)出的(de)廢水(shui)(shui)，主(zhu)要來源于居住建(jian)筑和(he)(he)公共(gong)建(jian)筑，如(ru)住宅、機(ji)關、學校、醫院、商店、公共(gong)場所(suo)及工業企業衛生(sheng)(sheng)(sheng)間等(deng)。生(sheng)(sheng)(sheng)活(huo)(huo)污(wu)(wu)水(shui)(shui)所(suo)含(han)的(de)污(wu)(wu)染(ran)物(wu)主(zhu)要是有機(ji)物(wu)(如(ru)蛋白質、碳水(shui)(shui)化合(he)物(wu)、脂肪、尿素、氨氮等(deng)) 和(he)(he)大量病(bing)(bing)原微(wei)生(sheng)(sheng)(sheng)物(wu)(如(ru)寄(ji)生(sheng)(sheng)(sheng)蟲卵(luan)和(he)(he)腸道傳(chuan)染(ran)病(bing)(bing)毒(du)等(deng))。存在于生(sheng)(sheng)(sheng)活(huo)(huo)污(wu)(wu)水(shui)(shui)中(zhong)的(de)有機(ji)物(wu)極不穩定，容易腐化而產生(sheng)(sheng)(sheng)惡臭。細菌和(he)(he)病(bing)(bing)原體(ti)以生(sheng)(sheng)(sheng)活(huo)(huo)污(wu)(wu)水(shui)(shui)中(zhong)有機(ji)物(wu)為營(ying)養而大量繁殖(zhi)，可導致傳(chuan)染(ran)病(bing)(bing)蔓延(yan)流行。因此(ci)，生(sheng)(sheng)(sheng)活(huo)(huo)污(wu)(wu)水(shui)(shui)排(pai)放前必(bi)須進行處理。
