生活污水處理工程

生(sheng)(sheng)活(huo)污(wu)水(shui)(shui)(shui)(shui)是居民日常生(sheng)(sheng)活(huo)中(zhong)(zhong)排出的廢水(shui)(shui)(shui)(shui)，主要來(lai)源于(yu)居住建筑和公共建筑，如住宅、機關、學校、醫院(yuan)、商店、公共場所及(ji)工業(ye)企業(ye)衛生(sheng)(sheng)間等(deng)(deng)。生(sheng)(sheng)活(huo)污(wu)水(shui)(shui)(shui)(shui)所含(han)的污(wu)染物主要是有(you)機物(如蛋白質、碳水(shui)(shui)(shui)(shui)化合物、脂肪、尿素、氨氮等(deng)(deng)) 和大量病原微生(sheng)(sheng)物(如寄生(sheng)(sheng)蟲(chong)卵和腸道傳染病毒(du)等(deng)(deng))。存在于(yu)生(sheng)(sheng)活(huo)污(wu)水(shui)(shui)(shui)(shui)中(zhong)(zhong)的有(you)機物極(ji)不穩定，容(rong)易腐(fu)化而產生(sheng)(sheng)惡(e)臭。細菌和病原體以生(sheng)(sheng)活(huo)污(wu)水(shui)(shui)(shui)(shui)中(zhong)(zhong)有(you)機物為營養而大量繁殖，可導致傳染病蔓延流行(xing)。因此，生(sheng)(sheng)活(huo)污(wu)水(shui)(shui)(shui)(shui)排放前(qian)必須進(jin)行(xing)處理(li)。
