生活污水處理工程

生(sheng)(sheng)活(huo)(huo)(huo)(huo)污(wu)水(shui)(shui)(shui)(shui)是居民日常生(sheng)(sheng)活(huo)(huo)(huo)(huo)中(zhong)排出的廢(fei)水(shui)(shui)(shui)(shui)，主(zhu)要來(lai)源于居住建筑和(he)公共建筑，如住宅、機(ji)(ji)關、學(xue)校、醫院、商店(dian)、公共場所及(ji)工業(ye)(ye)企(qi)業(ye)(ye)衛生(sheng)(sheng)間等。生(sheng)(sheng)活(huo)(huo)(huo)(huo)污(wu)水(shui)(shui)(shui)(shui)所含的污(wu)染(ran)(ran)物(wu)主(zhu)要是有(you)機(ji)(ji)物(wu)(如蛋白質、碳水(shui)(shui)(shui)(shui)化合物(wu)、脂肪、尿素(su)、氨氮等) 和(he)大量(liang)病原微生(sheng)(sheng)物(wu)(如寄生(sheng)(sheng)蟲卵和(he)腸道傳染(ran)(ran)病毒等)。存在于生(sheng)(sheng)活(huo)(huo)(huo)(huo)污(wu)水(shui)(shui)(shui)(shui)中(zhong)的有(you)機(ji)(ji)物(wu)極不(bu)穩定，容(rong)易(yi)腐化而產生(sheng)(sheng)惡(e)臭。細菌和(he)病原體以生(sheng)(sheng)活(huo)(huo)(huo)(huo)污(wu)水(shui)(shui)(shui)(shui)中(zhong)有(you)機(ji)(ji)物(wu)為營養而大量(liang)繁(fan)殖，可導(dao)致傳染(ran)(ran)病蔓延流行(xing)(xing)。因此(ci)，生(sheng)(sheng)活(huo)(huo)(huo)(huo)污(wu)水(shui)(shui)(shui)(shui)排放前必(bi)須進行(xing)(xing)處(chu)理。
