生活污水處理工程

生(sheng)(sheng)(sheng)(sheng)活污水是(shi)居(ju)民日(ri)常生(sheng)(sheng)(sheng)(sheng)活中(zhong)(zhong)排(pai)出的廢水，主(zhu)要(yao)(yao)來源于(yu)居(ju)住建筑(zhu)和(he)公共(gong)建筑(zhu)，如(ru)住宅(zhai)、機關、學校、醫院(yuan)、商(shang)店、公共(gong)場所及工業企業衛生(sheng)(sheng)(sheng)(sheng)間等(deng)。生(sheng)(sheng)(sheng)(sheng)活污水所含的污染物(wu)主(zhu)要(yao)(yao)是(shi)有(you)機物(wu)(如(ru)蛋白質、碳(tan)水化(hua)合物(wu)、脂肪、尿素(su)、氨氮(dan)等(deng)) 和(he)大(da)量(liang)病(bing)(bing)原微生(sheng)(sheng)(sheng)(sheng)物(wu)(如(ru)寄生(sheng)(sheng)(sheng)(sheng)蟲卵(luan)和(he)腸道(dao)傳染病(bing)(bing)毒(du)等(deng))。存在于(yu)生(sheng)(sheng)(sheng)(sheng)活污水中(zhong)(zhong)的有(you)機物(wu)極不穩(wen)定(ding)，容易腐化(hua)而(er)產生(sheng)(sheng)(sheng)(sheng)惡臭。細菌和(he)病(bing)(bing)原體(ti)以生(sheng)(sheng)(sheng)(sheng)活污水中(zhong)(zhong)有(you)機物(wu)為(wei)營養而(er)大(da)量(liang)繁(fan)殖，可導致傳染病(bing)(bing)蔓延流行。因(yin)此(ci)，生(sheng)(sheng)(sheng)(sheng)活污水排(pai)放前必須進行處(chu)理。
