生活污水處理工程

生(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)活(huo)污(wu)水(shui)(shui)是(shi)居民日常生(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)活(huo)中排(pai)出的(de)廢(fei)水(shui)(shui)，主要來(lai)源(yuan)于居住建筑和(he)公共建筑，如住宅、機(ji)關、學校、醫院(yuan)、商店、公共場所(suo)(suo)及工(gong)業企(qi)業衛生(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)間等。生(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)活(huo)污(wu)水(shui)(shui)所(suo)(suo)含的(de)污(wu)染(ran)物(wu)主要是(shi)有(you)機(ji)物(wu)(如蛋白質(zhi)、碳水(shui)(shui)化合(he)物(wu)、脂(zhi)肪、尿(niao)素(su)、氨氮等) 和(he)大量病(bing)原微生(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)物(wu)(如寄生(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)蟲卵和(he)腸道(dao)傳染(ran)病(bing)毒等)。存在于生(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)活(huo)污(wu)水(shui)(shui)中的(de)有(you)機(ji)物(wu)極不穩(wen)定(ding)，容(rong)易腐化而(er)產生(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)惡臭。細菌和(he)病(bing)原體以(yi)生(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)活(huo)污(wu)水(shui)(shui)中有(you)機(ji)物(wu)為營養而(er)大量繁殖，可導(dao)致傳染(ran)病(bing)蔓延流(liu)行。因此，生(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)活(huo)污(wu)水(shui)(shui)排(pai)放(fang)前必須進行處理。
