生活污水處理工程

生(sheng)(sheng)(sheng)活(huo)污(wu)水(shui)是(shi)居民(min)日(ri)常生(sheng)(sheng)(sheng)活(huo)中排(pai)出的廢水(shui)，主(zhu)(zhu)要來源于居住(zhu)建(jian)筑(zhu)和公共(gong)建(jian)筑(zhu)，如(ru)住(zhu)宅、機(ji)關、學校、醫院、商店(dian)、公共(gong)場所及工業(ye)企業(ye)衛生(sheng)(sheng)(sheng)間等。生(sheng)(sheng)(sheng)活(huo)污(wu)水(shui)所含的污(wu)染物(wu)(wu)(wu)主(zhu)(zhu)要是(shi)有機(ji)物(wu)(wu)(wu)(如(ru)蛋白質、碳(tan)水(shui)化合物(wu)(wu)(wu)、脂(zhi)肪、尿素、氨氮(dan)等) 和大量(liang)病(bing)原微生(sheng)(sheng)(sheng)物(wu)(wu)(wu)(如(ru)寄(ji)生(sheng)(sheng)(sheng)蟲卵和腸(chang)道傳(chuan)染病(bing)毒等)。存在于生(sheng)(sheng)(sheng)活(huo)污(wu)水(shui)中的有機(ji)物(wu)(wu)(wu)極不穩定(ding)，容易腐化而(er)產生(sheng)(sheng)(sheng)惡(e)臭。細(xi)菌(jun)和病(bing)原體(ti)以生(sheng)(sheng)(sheng)活(huo)污(wu)水(shui)中有機(ji)物(wu)(wu)(wu)為營養而(er)大量(liang)繁(fan)殖，可導致傳(chuan)染病(bing)蔓(man)延(yan)流行。因此，生(sheng)(sheng)(sheng)活(huo)污(wu)水(shui)排(pai)放(fang)前必(bi)須進行處理。
