生活污水處理工程

生(sheng)(sheng)(sheng)活(huo)污(wu)水(shui)(shui)是居(ju)民日常生(sheng)(sheng)(sheng)活(huo)中(zhong)(zhong)排出的(de)廢(fei)水(shui)(shui)，主要來源(yuan)于居(ju)住(zhu)建(jian)筑(zhu)和(he)公共建(jian)筑(zhu)，如住(zhu)宅、機關、學(xue)校、醫院、商店、公共場所(suo)及工(gong)業企業衛生(sheng)(sheng)(sheng)間等。生(sheng)(sheng)(sheng)活(huo)污(wu)水(shui)(shui)所(suo)含(han)的(de)污(wu)染物(wu)主要是有(you)機物(wu)(如蛋白(bai)質、碳水(shui)(shui)化(hua)合物(wu)、脂肪、尿素、氨氮等) 和(he)大量(liang)病原微(wei)生(sheng)(sheng)(sheng)物(wu)(如寄生(sheng)(sheng)(sheng)蟲卵和(he)腸道傳染病毒等)。存在于生(sheng)(sheng)(sheng)活(huo)污(wu)水(shui)(shui)中(zhong)(zhong)的(de)有(you)機物(wu)極不(bu)穩定，容易腐化(hua)而產生(sheng)(sheng)(sheng)惡臭。細菌和(he)病原體以生(sheng)(sheng)(sheng)活(huo)污(wu)水(shui)(shui)中(zhong)(zhong)有(you)機物(wu)為營養而大量(liang)繁殖(zhi)，可導致傳染病蔓延流(liu)行(xing)。因此，生(sheng)(sheng)(sheng)活(huo)污(wu)水(shui)(shui)排放前必須進行(xing)處理。
