生活污水處理工程

生(sheng)(sheng)(sheng)(sheng)(sheng)活污水(shui)是居(ju)民(min)日常生(sheng)(sheng)(sheng)(sheng)(sheng)活中(zhong)排出的(de)(de)廢水(shui)，主(zhu)要來(lai)源(yuan)于(yu)(yu)居(ju)住建筑(zhu)和公共(gong)建筑(zhu)，如住宅(zhai)、機(ji)關(guan)、學校、醫院、商(shang)店(dian)、公共(gong)場所(suo)及工(gong)業企業衛生(sheng)(sheng)(sheng)(sheng)(sheng)間(jian)等(deng)(deng)。生(sheng)(sheng)(sheng)(sheng)(sheng)活污水(shui)所(suo)含的(de)(de)污染物主(zhu)要是有(you)(you)機(ji)物(如蛋白質、碳水(shui)化(hua)合物、脂肪、尿素、氨氮(dan)等(deng)(deng)) 和大量病(bing)(bing)原微生(sheng)(sheng)(sheng)(sheng)(sheng)物(如寄生(sheng)(sheng)(sheng)(sheng)(sheng)蟲卵和腸道傳染病(bing)(bing)毒(du)等(deng)(deng))。存在于(yu)(yu)生(sheng)(sheng)(sheng)(sheng)(sheng)活污水(shui)中(zhong)的(de)(de)有(you)(you)機(ji)物極(ji)不(bu)穩定(ding)，容易腐(fu)化(hua)而產生(sheng)(sheng)(sheng)(sheng)(sheng)惡(e)臭。細(xi)菌和病(bing)(bing)原體以(yi)生(sheng)(sheng)(sheng)(sheng)(sheng)活污水(shui)中(zhong)有(you)(you)機(ji)物為營養(yang)而大量繁殖(zhi)，可導(dao)致傳染病(bing)(bing)蔓(man)延流行。因此(ci)，生(sheng)(sheng)(sheng)(sheng)(sheng)活污水(shui)排放前必須(xu)進行處(chu)理。
