摘　　要：本文考察了厌氧-缺氧-移动床复合生物处理工艺(anoxic+anaerobic/moving-bed biofilm reactor,A2/MBBR)在长期运行下对模拟生活污水的净化效能,在水力停留时间为6.8 h,溶解氧为1.5~2.5 mg/L的条件下,中试运行1个月,稳定运行6个月,生物需氧量(BOD)平均去除率可达到94%以上、化学需氧量(COD)的平均去除率可达到91%以上、NH4+-N平均去除率为98%、总氮(TN)的去除率可达到76%以上、总磷(TP)的去除率可达到81%以上,达到回用水水源标准.The contaminant removal efficiency of A^2/MBBR process used in purification of simulated domestic wastewater was investigated. Under the hydraulic retention time of 6.8 h and dissolved oxygen of 1.5 - 2. 5 mg/L conditions, the pilot-scale equipment continuously ran for one month. After six months stable running,A^2/MBBR process displayed positive effects in wastewater treatment. The results shown that the average removal efficiency of BOD,COD,NH4^＋-N,TN and TP reached 94% ,91% ,98% ,76% and 81% or more,respectively. These indexes have met the request of reused water.
