生活污水處理工程

生(sheng)(sheng)(sheng)(sheng)(sheng)活污(wu)(wu)水(shui)(shui)(shui)(shui)是(shi)居(ju)民(min)日(ri)常生(sheng)(sheng)(sheng)(sheng)(sheng)活中排出的(de)(de)廢水(shui)(shui)(shui)(shui)，主要(yao)來源于居(ju)住(zhu)建(jian)筑(zhu)和公共建(jian)筑(zhu)，如(ru)住(zhu)宅、機關、學校(xiao)、醫院、商(shang)店(dian)、公共場所及工業(ye)(ye)企業(ye)(ye)衛生(sheng)(sheng)(sheng)(sheng)(sheng)間等。生(sheng)(sheng)(sheng)(sheng)(sheng)活污(wu)(wu)水(shui)(shui)(shui)(shui)所含(han)的(de)(de)污(wu)(wu)染(ran)物(wu)(wu)(wu)主要(yao)是(shi)有(you)(you)機物(wu)(wu)(wu)(如(ru)蛋白質、碳水(shui)(shui)(shui)(shui)化(hua)合物(wu)(wu)(wu)、脂肪、尿素、氨(an)氮等) 和大量(liang)病原微生(sheng)(sheng)(sheng)(sheng)(sheng)物(wu)(wu)(wu)(如(ru)寄生(sheng)(sheng)(sheng)(sheng)(sheng)蟲卵和腸(chang)道傳染(ran)病毒等)。存在于生(sheng)(sheng)(sheng)(sheng)(sheng)活污(wu)(wu)水(shui)(shui)(shui)(shui)中的(de)(de)有(you)(you)機物(wu)(wu)(wu)極不穩定，容易腐化(hua)而(er)產生(sheng)(sheng)(sheng)(sheng)(sheng)惡臭(chou)。細(xi)菌和病原體以(yi)生(sheng)(sheng)(sheng)(sheng)(sheng)活污(wu)(wu)水(shui)(shui)(shui)(shui)中有(you)(you)機物(wu)(wu)(wu)為營養(yang)而(er)大量(liang)繁殖，可導(dao)致(zhi)傳染(ran)病蔓延流行。因此(ci)，生(sheng)(sheng)(sheng)(sheng)(sheng)活污(wu)(wu)水(shui)(shui)(shui)(shui)排放前必須進行處(chu)理。
