摘　　要：根据兼性塘和A/O工艺原理,提出并设计了升流式一体化A/O生物膜反应器(UFIBR),并就反应器处理生活污水的效果和运行参数进行了试验研究。结果表明,当缺氧区HRT5h,好氧区HRT3h,在几种运行条件下,COD、BOD5、SS和NH+4-N平均去除率分别为86.7%,91%,95%和72%;总氮平均去除率当回流比为100%时为40%,回流比为200%时为57%的;缺氧段处于酸化状态;剩余污泥少,无需频繁排泥。According to the principles of Facultative Pond and A/O process,an Upflow Integrated A/O Biofilm Reactor (UFIBR) was brought forward and designed for the first time.The treatment effect on domestic wastewater by the reactor (UFIBR) and its running parameters were studied in laboratory scale. In case when HRT in anoxic area is 5h, and HRT in aerobic area is 3h, high removal efficiencies can be achieved for various parameters, such as COD 86.7%, BOD5 91%, and NH4-N72%; mean removal of 40%, 57% for TN under recycling rate of 100% and 200% respectively can be guaranteed.The anoxic area is observed to be on acidification stage.Some microorganism grows as biofilm, the yield of waste sludge is low in UFIBR.
