生活污水處理工程

生(sheng)(sheng)(sheng)(sheng)活(huo)(huo)污(wu)(wu)水是居民日常生(sheng)(sheng)(sheng)(sheng)活(huo)(huo)中排出(chu)的廢水，主(zhu)要來源于居住建筑和公共建筑，如住宅、機(ji)(ji)關、學校、醫院、商店、公共場(chang)所及工業企業衛生(sheng)(sheng)(sheng)(sheng)間等。生(sheng)(sheng)(sheng)(sheng)活(huo)(huo)污(wu)(wu)水所含的污(wu)(wu)染(ran)物主(zhu)要是有(you)(you)機(ji)(ji)物(如蛋白質、碳水化合物、脂肪(fang)、尿素、氨氮等) 和大(da)量(liang)病(bing)原微生(sheng)(sheng)(sheng)(sheng)物(如寄生(sheng)(sheng)(sheng)(sheng)蟲(chong)卵和腸道傳染(ran)病(bing)毒等)。存在于生(sheng)(sheng)(sheng)(sheng)活(huo)(huo)污(wu)(wu)水中的有(you)(you)機(ji)(ji)物極不穩定，容易腐(fu)化而產生(sheng)(sheng)(sheng)(sheng)惡臭(chou)。細菌和病(bing)原體(ti)以生(sheng)(sheng)(sheng)(sheng)活(huo)(huo)污(wu)(wu)水中有(you)(you)機(ji)(ji)物為營養而大(da)量(liang)繁殖，可導致傳染(ran)病(bing)蔓(man)延流(liu)行。因此，生(sheng)(sheng)(sheng)(sheng)活(huo)(huo)污(wu)(wu)水排放前必(bi)須進行處(chu)理。
