摘　　要：试验表明 ,生物接触A/O工艺对官厅水库入库水中COD、氨氮等污染物有明显的去除效果 ,可以有效地改善官厅水库入库水的水质 .在单位供气量 (空气 /氨氮 )≥ 0 1L/mg ,进水氨氮负荷≤ 0 0 8kg/ (m3 ·d)的条件下 ,处理后出水COD稳定在 30mg/L左右 ,氨氮去除率 >6 0 % ,TN的去除率为 1 0 %～ 31 3% .进水氨氮负荷是主要的控制参数 ,应控制在≤ 0 0 8kg/ (m3 ·d) .The results of the experiments showed that biological contact A/O process had evident removal effect of contaminations such as COD、ammonia nitrogen in water entering into Guanting Reservior and could successfully resume the quality. Under the conditions that air supply flux(gas/ ammonia nitrogen)was more than 0.1L/mg and influent ammonia nitrogen loading was lower than 0.08kg/(m 3·d), effluent COD was steadily 30mg/L around, ammonia nitrogen removal rate was higher than 60%, and TN removal rate was 1.0%～31.3%.The main control parameter was influent ammonia nitrogen loading, which was proposed to be lower than 0.08kg/(m 3·d).
