生活污水處理工程

生(sheng)(sheng)(sheng)(sheng)活(huo)污(wu)水(shui)是(shi)居民日常生(sheng)(sheng)(sheng)(sheng)活(huo)中排出的廢水(shui)，主要來源于居住建筑和公(gong)共建筑，如(ru)住宅、機(ji)(ji)關(guan)、學(xue)校、醫院、商店、公(gong)共場所(suo)及(ji)工業企業衛生(sheng)(sheng)(sheng)(sheng)間等。生(sheng)(sheng)(sheng)(sheng)活(huo)污(wu)水(shui)所(suo)含的污(wu)染(ran)物主要是(shi)有(you)(you)機(ji)(ji)物(如(ru)蛋白質、碳(tan)水(shui)化合物、脂肪、尿(niao)素、氨氮等) 和大量病原微生(sheng)(sheng)(sheng)(sheng)物(如(ru)寄生(sheng)(sheng)(sheng)(sheng)蟲(chong)卵和腸道傳染(ran)病毒等)。存在于生(sheng)(sheng)(sheng)(sheng)活(huo)污(wu)水(shui)中的有(you)(you)機(ji)(ji)物極不(bu)穩定，容(rong)易腐化而產(chan)生(sheng)(sheng)(sheng)(sheng)惡臭。細菌和病原體以生(sheng)(sheng)(sheng)(sheng)活(huo)污(wu)水(shui)中有(you)(you)機(ji)(ji)物為營養而大量繁殖(zhi)，可導致傳染(ran)病蔓延(yan)流行。因此(ci)，生(sheng)(sheng)(sheng)(sheng)活(huo)污(wu)水(shui)排放(fang)前必須(xu)進行處(chu)理。
