摘　　要：采用UASB-生物接触氧化组合工艺处理猪粪污水,研究其对高浓度有机废水的处理效果。结果表明,污水经过初次沉淀、厌氧、好氧、混凝沉淀、过滤、消毒等处理后,化学需氧量(CODcr)、生物需氧量(BOD5)、悬浮物(SS)、氨氮(NH3-N)去除率分别达到99%、99.5%、98.7%、99.7%;大肠杆菌和蛔虫卵均未检出;出水水质达到了国家中水回用标准(GJ/T48-1999),完全可以作为猪栏冲洗用水,达到中水回用的目的。Study on advanced treatment of piggery wastewater with UASB-biological contact oxidation was conducted to research the effect of treatment on high concentration organic wastewater. The results showed that the removal ratios of CODcr, BOD5, SS and NH3-N separately reached high levels of 99%, 99.5%, 98.7% and 99.7% after treatments of initial deposition, anaerobic, aerobic, flocculation sedimentation, filtration and disinfection. Colon bacillus and Helminthic nit were not detected. The treated wastewater can reach the national standard of reclaimed water reuse （GJ/T48-1999）and can be used as washing water for piggery.
