生活污水處理工程

生(sheng)(sheng)(sheng)活(huo)污(wu)水(shui)(shui)是(shi)居民日常生(sheng)(sheng)(sheng)活(huo)中排出(chu)的廢水(shui)(shui)，主(zhu)要來源(yuan)于居住(zhu)建筑和(he)公(gong)(gong)共建筑，如(ru)住(zhu)宅、機(ji)關、學校、醫院、商(shang)店(dian)、公(gong)(gong)共場所(suo)及工業企業衛生(sheng)(sheng)(sheng)間等(deng)。生(sheng)(sheng)(sheng)活(huo)污(wu)水(shui)(shui)所(suo)含(han)的污(wu)染物(wu)主(zhu)要是(shi)有機(ji)物(wu)(如(ru)蛋(dan)白質、碳水(shui)(shui)化合物(wu)、脂肪、尿素(su)、氨氮等(deng)) 和(he)大(da)量病(bing)(bing)原(yuan)微生(sheng)(sheng)(sheng)物(wu)(如(ru)寄生(sheng)(sheng)(sheng)蟲卵和(he)腸道(dao)傳染病(bing)(bing)毒等(deng))。存在于生(sheng)(sheng)(sheng)活(huo)污(wu)水(shui)(shui)中的有機(ji)物(wu)極(ji)不穩定(ding)，容易腐(fu)化而產(chan)生(sheng)(sheng)(sheng)惡臭。細(xi)菌和(he)病(bing)(bing)原(yuan)體以生(sheng)(sheng)(sheng)活(huo)污(wu)水(shui)(shui)中有機(ji)物(wu)為營養而大(da)量繁殖，可導致傳染病(bing)(bing)蔓延流行。因此，生(sheng)(sheng)(sheng)活(huo)污(wu)水(shui)(shui)排放前必須進行處理。
