生活污水處理工程

生(sheng)(sheng)(sheng)活(huo)(huo)(huo)污(wu)(wu)水(shui)(shui)(shui)是(shi)居民日常生(sheng)(sheng)(sheng)活(huo)(huo)(huo)中排出的(de)(de)廢水(shui)(shui)(shui)，主要來(lai)源(yuan)于(yu)居住建筑和公共建筑，如(ru)住宅、機(ji)(ji)關、學校、醫院、商店、公共場(chang)所及(ji)工業(ye)企業(ye)衛(wei)生(sheng)(sheng)(sheng)間等。生(sheng)(sheng)(sheng)活(huo)(huo)(huo)污(wu)(wu)水(shui)(shui)(shui)所含的(de)(de)污(wu)(wu)染(ran)物主要是(shi)有(you)機(ji)(ji)物(如(ru)蛋白質、碳水(shui)(shui)(shui)化合物、脂肪、尿(niao)素、氨氮等) 和大量(liang)病(bing)原(yuan)微生(sheng)(sheng)(sheng)物(如(ru)寄生(sheng)(sheng)(sheng)蟲(chong)卵和腸道傳染(ran)病(bing)毒(du)等)。存在于(yu)生(sheng)(sheng)(sheng)活(huo)(huo)(huo)污(wu)(wu)水(shui)(shui)(shui)中的(de)(de)有(you)機(ji)(ji)物極不(bu)穩(wen)定，容易(yi)腐(fu)化而產生(sheng)(sheng)(sheng)惡(e)臭。細菌(jun)和病(bing)原(yuan)體以生(sheng)(sheng)(sheng)活(huo)(huo)(huo)污(wu)(wu)水(shui)(shui)(shui)中有(you)機(ji)(ji)物為營養而大量(liang)繁(fan)殖，可導致傳染(ran)病(bing)蔓延(yan)流行(xing)。因此，生(sheng)(sheng)(sheng)活(huo)(huo)(huo)污(wu)(wu)水(shui)(shui)(shui)排放前必須進行(xing)處理。
