生活污水處理工程

生(sheng)(sheng)(sheng)(sheng)活(huo)污(wu)水(shui)(shui)是居民(min)日常生(sheng)(sheng)(sheng)(sheng)活(huo)中(zhong)(zhong)排出(chu)的廢水(shui)(shui)，主要來源于居住(zhu)建筑和(he)公共(gong)建筑，如住(zhu)宅、機(ji)關、學校、醫(yi)院、商店、公共(gong)場所及(ji)工業企業衛生(sheng)(sheng)(sheng)(sheng)間等(deng)(deng)。生(sheng)(sheng)(sheng)(sheng)活(huo)污(wu)水(shui)(shui)所含的污(wu)染(ran)物主要是有機(ji)物(如蛋白質、碳水(shui)(shui)化合物、脂肪、尿(niao)素(su)、氨氮(dan)等(deng)(deng)) 和(he)大(da)量(liang)病(bing)(bing)原(yuan)微(wei)生(sheng)(sheng)(sheng)(sheng)物(如寄(ji)生(sheng)(sheng)(sheng)(sheng)蟲卵和(he)腸道傳染(ran)病(bing)(bing)毒等(deng)(deng))。存在于生(sheng)(sheng)(sheng)(sheng)活(huo)污(wu)水(shui)(shui)中(zhong)(zhong)的有機(ji)物極不(bu)穩定，容易(yi)腐(fu)化而產生(sheng)(sheng)(sheng)(sheng)惡臭。細(xi)菌和(he)病(bing)(bing)原(yuan)體(ti)以生(sheng)(sheng)(sheng)(sheng)活(huo)污(wu)水(shui)(shui)中(zhong)(zhong)有機(ji)物為營養而大(da)量(liang)繁殖，可(ke)導致(zhi)傳染(ran)病(bing)(bing)蔓延(yan)流行。因此，生(sheng)(sheng)(sheng)(sheng)活(huo)污(wu)水(shui)(shui)排放前必須(xu)進行處理。
