生活污水處理工程

生(sheng)活(huo)污(wu)(wu)水(shui)(shui)(shui)(shui)(shui)是(shi)居民日常生(sheng)活(huo)中(zhong)排(pai)出的廢水(shui)(shui)(shui)(shui)(shui)，主要(yao)來源于(yu)居住(zhu)建筑(zhu)和(he)(he)公(gong)共(gong)(gong)建筑(zhu)，如住(zhu)宅、機關(guan)、學(xue)校、醫院、商店、公(gong)共(gong)(gong)場(chang)所及(ji)工業(ye)企業(ye)衛生(sheng)間等。生(sheng)活(huo)污(wu)(wu)水(shui)(shui)(shui)(shui)(shui)所含的污(wu)(wu)染物(wu)主要(yao)是(shi)有機物(wu)(如蛋白質(zhi)、碳水(shui)(shui)(shui)(shui)(shui)化合(he)物(wu)、脂(zhi)肪、尿素、氨(an)氮等) 和(he)(he)大量病(bing)(bing)原(yuan)微生(sheng)物(wu)(如寄生(sheng)蟲卵和(he)(he)腸道(dao)傳染病(bing)(bing)毒(du)等)。存(cun)在于(yu)生(sheng)活(huo)污(wu)(wu)水(shui)(shui)(shui)(shui)(shui)中(zhong)的有機物(wu)極不穩定(ding)，容易腐(fu)化而產生(sheng)惡臭。細菌和(he)(he)病(bing)(bing)原(yuan)體以生(sheng)活(huo)污(wu)(wu)水(shui)(shui)(shui)(shui)(shui)中(zhong)有機物(wu)為營養(yang)而大量繁殖，可導致傳染病(bing)(bing)蔓延流行。因此，生(sheng)活(huo)污(wu)(wu)水(shui)(shui)(shui)(shui)(shui)排(pai)放前(qian)必須進行處理。
