生活污水處理工程

生(sheng)(sheng)(sheng)活(huo)(huo)污(wu)水(shui)(shui)(shui)是居民(min)日常生(sheng)(sheng)(sheng)活(huo)(huo)中(zhong)排出的廢水(shui)(shui)(shui)，主要來(lai)源于居住(zhu)建筑和公共(gong)建筑，如(ru)住(zhu)宅、機(ji)關、學校、醫院(yuan)、商店(dian)、公共(gong)場所及工(gong)業(ye)企(qi)業(ye)衛(wei)生(sheng)(sheng)(sheng)間等(deng)(deng)。生(sheng)(sheng)(sheng)活(huo)(huo)污(wu)水(shui)(shui)(shui)所含的污(wu)染物(wu)(wu)主要是有(you)機(ji)物(wu)(wu)(如(ru)蛋白質、碳水(shui)(shui)(shui)化合物(wu)(wu)、脂(zhi)肪、尿素、氨氮(dan)等(deng)(deng)) 和大量(liang)病原(yuan)微(wei)生(sheng)(sheng)(sheng)物(wu)(wu)(如(ru)寄生(sheng)(sheng)(sheng)蟲(chong)卵(luan)和腸(chang)道(dao)傳染病毒等(deng)(deng))。存(cun)在(zai)于生(sheng)(sheng)(sheng)活(huo)(huo)污(wu)水(shui)(shui)(shui)中(zhong)的有(you)機(ji)物(wu)(wu)極(ji)不穩定，容易腐化而產生(sheng)(sheng)(sheng)惡臭。細菌和病原(yuan)體(ti)以生(sheng)(sheng)(sheng)活(huo)(huo)污(wu)水(shui)(shui)(shui)中(zhong)有(you)機(ji)物(wu)(wu)為營(ying)養而大量(liang)繁(fan)殖，可導致傳染病蔓延(yan)流行。因此，生(sheng)(sheng)(sheng)活(huo)(huo)污(wu)水(shui)(shui)(shui)排放前必須進行處(chu)理。
