生活污水處理工程

生(sheng)(sheng)(sheng)活(huo)污水(shui)是(shi)(shi)居民日常生(sheng)(sheng)(sheng)活(huo)中排出(chu)的廢水(shui)，主(zhu)(zhu)要來源于(yu)居住(zhu)建筑和公(gong)共(gong)建筑，如(ru)住(zhu)宅、機關(guan)、學校、醫院、商店、公(gong)共(gong)場所及工(gong)業企業衛生(sheng)(sheng)(sheng)間等。生(sheng)(sheng)(sheng)活(huo)污水(shui)所含的污染物(wu)主(zhu)(zhu)要是(shi)(shi)有(you)機物(wu)(如(ru)蛋(dan)白質、碳水(shui)化合物(wu)、脂肪、尿(niao)素、氨氮等) 和大量(liang)病(bing)原(yuan)微生(sheng)(sheng)(sheng)物(wu)(如(ru)寄生(sheng)(sheng)(sheng)蟲(chong)卵和腸道傳染病(bing)毒等)。存在于(yu)生(sheng)(sheng)(sheng)活(huo)污水(shui)中的有(you)機物(wu)極不穩定，容易腐化而(er)產生(sheng)(sheng)(sheng)惡臭。細菌和病(bing)原(yuan)體以生(sheng)(sheng)(sheng)活(huo)污水(shui)中有(you)機物(wu)為營養而(er)大量(liang)繁(fan)殖，可導致傳染病(bing)蔓延流(liu)行。因(yin)此，生(sheng)(sheng)(sheng)活(huo)污水(shui)排放前必須進行處(chu)理。
