生活污水處理工程

生(sheng)(sheng)(sheng)(sheng)活污水(shui)(shui)是居民日常生(sheng)(sheng)(sheng)(sheng)活中(zhong)(zhong)(zhong)排(pai)出的(de)廢水(shui)(shui)，主(zhu)要(yao)來源于居住(zhu)建(jian)筑(zhu)(zhu)和(he)公共建(jian)筑(zhu)(zhu)，如住(zhu)宅、機關、學校、醫院、商店(dian)、公共場所及(ji)工業企(qi)業衛生(sheng)(sheng)(sheng)(sheng)間等(deng)(deng)。生(sheng)(sheng)(sheng)(sheng)活污水(shui)(shui)所含的(de)污染物(wu)(wu)主(zhu)要(yao)是有(you)機物(wu)(wu)(如蛋白質、碳水(shui)(shui)化(hua)合物(wu)(wu)、脂肪、尿(niao)素、氨氮(dan)等(deng)(deng)) 和(he)大(da)量病(bing)原(yuan)微生(sheng)(sheng)(sheng)(sheng)物(wu)(wu)(如寄生(sheng)(sheng)(sheng)(sheng)蟲卵(luan)和(he)腸道傳染病(bing)毒等(deng)(deng))。存在于生(sheng)(sheng)(sheng)(sheng)活污水(shui)(shui)中(zhong)(zhong)(zhong)的(de)有(you)機物(wu)(wu)極不穩定，容易(yi)腐化(hua)而產生(sheng)(sheng)(sheng)(sheng)惡(e)臭。細(xi)菌(jun)和(he)病(bing)原(yuan)體以生(sheng)(sheng)(sheng)(sheng)活污水(shui)(shui)中(zhong)(zhong)(zhong)有(you)機物(wu)(wu)為營(ying)養(yang)而大(da)量繁殖(zhi)，可(ke)導致傳染病(bing)蔓延流行。因此(ci)，生(sheng)(sheng)(sheng)(sheng)活污水(shui)(shui)排(pai)放前(qian)必(bi)須進行處理。
