生活污水處理工程

生(sheng)(sheng)(sheng)活(huo)污(wu)(wu)水(shui)是(shi)居(ju)民日常生(sheng)(sheng)(sheng)活(huo)中(zhong)(zhong)排(pai)出的廢水(shui)，主要(yao)來源于居(ju)住建(jian)筑和公(gong)共(gong)建(jian)筑，如住宅、機(ji)關、學校、醫(yi)院、商店(dian)、公(gong)共(gong)場(chang)所及工業企業衛生(sheng)(sheng)(sheng)間等。生(sheng)(sheng)(sheng)活(huo)污(wu)(wu)水(shui)所含(han)的污(wu)(wu)染(ran)(ran)(ran)物(wu)主要(yao)是(shi)有(you)(you)機(ji)物(wu)(如蛋白質、碳水(shui)化(hua)合物(wu)、脂(zhi)肪、尿(niao)素、氨氮(dan)等) 和大(da)量(liang)病原微生(sheng)(sheng)(sheng)物(wu)(如寄生(sheng)(sheng)(sheng)蟲(chong)卵和腸道傳(chuan)染(ran)(ran)(ran)病毒等)。存(cun)在于生(sheng)(sheng)(sheng)活(huo)污(wu)(wu)水(shui)中(zhong)(zhong)的有(you)(you)機(ji)物(wu)極不穩定，容易腐化(hua)而產生(sheng)(sheng)(sheng)惡臭。細(xi)菌和病原體以生(sheng)(sheng)(sheng)活(huo)污(wu)(wu)水(shui)中(zhong)(zhong)有(you)(you)機(ji)物(wu)為營(ying)養(yang)而大(da)量(liang)繁殖，可導(dao)致傳(chuan)染(ran)(ran)(ran)病蔓延流行。因此(ci)，生(sheng)(sheng)(sheng)活(huo)污(wu)(wu)水(shui)排(pai)放前(qian)必須進行處(chu)理。
