生活污水處理工程

生(sheng)(sheng)(sheng)活(huo)(huo)(huo)污水(shui)(shui)(shui)是居民日常生(sheng)(sheng)(sheng)活(huo)(huo)(huo)中(zhong)(zhong)排(pai)出(chu)的(de)廢(fei)水(shui)(shui)(shui)，主(zhu)要來源(yuan)于居住(zhu)建(jian)筑(zhu)和公共(gong)建(jian)筑(zhu)，如(ru)住(zhu)宅、機(ji)關、學校(xiao)、醫院、商店、公共(gong)場所及工業企業衛生(sheng)(sheng)(sheng)間等。生(sheng)(sheng)(sheng)活(huo)(huo)(huo)污水(shui)(shui)(shui)所含(han)的(de)污染物(wu)主(zhu)要是有(you)機(ji)物(wu)(如(ru)蛋白(bai)質、碳(tan)水(shui)(shui)(shui)化合(he)物(wu)、脂肪、尿素、氨(an)氮等) 和大量(liang)病原微生(sheng)(sheng)(sheng)物(wu)(如(ru)寄生(sheng)(sheng)(sheng)蟲卵和腸道(dao)傳染病毒(du)等)。存(cun)在于生(sheng)(sheng)(sheng)活(huo)(huo)(huo)污水(shui)(shui)(shui)中(zhong)(zhong)的(de)有(you)機(ji)物(wu)極不穩定，容易腐化而產生(sheng)(sheng)(sheng)惡臭。細(xi)菌和病原體以生(sheng)(sheng)(sheng)活(huo)(huo)(huo)污水(shui)(shui)(shui)中(zhong)(zhong)有(you)機(ji)物(wu)為營養而大量(liang)繁殖(zhi)，可導(dao)致傳染病蔓延流行(xing)。因(yin)此(ci)，生(sheng)(sheng)(sheng)活(huo)(huo)(huo)污水(shui)(shui)(shui)排(pai)放前必須進行(xing)處理(li)。
