生活污水處理工程

生(sheng)(sheng)(sheng)(sheng)(sheng)活(huo)(huo)污水(shui)(shui)是居民(min)日常生(sheng)(sheng)(sheng)(sheng)(sheng)活(huo)(huo)中排出的廢水(shui)(shui)，主要(yao)來源于居住建(jian)筑和公(gong)共建(jian)筑，如(ru)住宅、機關、學校、醫(yi)院、商店、公(gong)共場所及工業企業衛生(sheng)(sheng)(sheng)(sheng)(sheng)間(jian)等。生(sheng)(sheng)(sheng)(sheng)(sheng)活(huo)(huo)污水(shui)(shui)所含(han)的污染(ran)物(wu)(wu)主要(yao)是有(you)機物(wu)(wu)(如(ru)蛋白(bai)質、碳水(shui)(shui)化合物(wu)(wu)、脂肪、尿素、氨氮(dan)等) 和大(da)量病(bing)(bing)原微生(sheng)(sheng)(sheng)(sheng)(sheng)物(wu)(wu)(如(ru)寄生(sheng)(sheng)(sheng)(sheng)(sheng)蟲卵和腸道傳染(ran)病(bing)(bing)毒等)。存在于生(sheng)(sheng)(sheng)(sheng)(sheng)活(huo)(huo)污水(shui)(shui)中的有(you)機物(wu)(wu)極(ji)不穩定，容易(yi)腐化而(er)產(chan)生(sheng)(sheng)(sheng)(sheng)(sheng)惡臭。細菌(jun)和病(bing)(bing)原體(ti)以生(sheng)(sheng)(sheng)(sheng)(sheng)活(huo)(huo)污水(shui)(shui)中有(you)機物(wu)(wu)為營養(yang)而(er)大(da)量繁殖，可導致(zhi)傳染(ran)病(bing)(bing)蔓(man)延流行(xing)。因此，生(sheng)(sheng)(sheng)(sheng)(sheng)活(huo)(huo)污水(shui)(shui)排放(fang)前必須進行(xing)處(chu)理。
