生活污水處理工程

生(sheng)(sheng)活(huo)(huo)污(wu)(wu)水(shui)(shui)(shui)(shui)是居民日常生(sheng)(sheng)活(huo)(huo)中(zhong)(zhong)排出的(de)(de)廢水(shui)(shui)(shui)(shui)，主要(yao)來源(yuan)于居住(zhu)建筑和公(gong)共(gong)建筑，如(ru)(ru)住(zhu)宅、機關、學校、醫院、商店(dian)、公(gong)共(gong)場所及工業(ye)企業(ye)衛(wei)生(sheng)(sheng)間等(deng)。生(sheng)(sheng)活(huo)(huo)污(wu)(wu)水(shui)(shui)(shui)(shui)所含的(de)(de)污(wu)(wu)染(ran)物(wu)(wu)(wu)(wu)主要(yao)是有機物(wu)(wu)(wu)(wu)(如(ru)(ru)蛋白質、碳水(shui)(shui)(shui)(shui)化合物(wu)(wu)(wu)(wu)、脂肪、尿素、氨氮等(deng)) 和大量(liang)病(bing)原微生(sheng)(sheng)物(wu)(wu)(wu)(wu)(如(ru)(ru)寄生(sheng)(sheng)蟲卵和腸(chang)道傳染(ran)病(bing)毒(du)等(deng))。存(cun)在于生(sheng)(sheng)活(huo)(huo)污(wu)(wu)水(shui)(shui)(shui)(shui)中(zhong)(zhong)的(de)(de)有機物(wu)(wu)(wu)(wu)極不穩定(ding)，容易腐(fu)化而產(chan)生(sheng)(sheng)惡(e)臭。細菌和病(bing)原體以生(sheng)(sheng)活(huo)(huo)污(wu)(wu)水(shui)(shui)(shui)(shui)中(zhong)(zhong)有機物(wu)(wu)(wu)(wu)為營養(yang)而大量(liang)繁殖，可導致傳染(ran)病(bing)蔓延流行。因(yin)此，生(sheng)(sheng)活(huo)(huo)污(wu)(wu)水(shui)(shui)(shui)(shui)排放前必須(xu)進行處理。
