摘　　要：采用A2O-MBR系统处理校园污水,考察该工艺对各类污染物的去除效果及其关键影响因素。研究结果表明:A2O-MBR工艺在稳定运行条件下各项出水水质优良,但由于受碳源限制,出水TP浓度不能稳定达标。水温对A2O-MBR系统去除CODCr和NH3-N的效果影响较小,而对TN去除效果的影响较为显著;低水温条件下维持系统污泥质量浓度在6 g/L以上可获得较高的NH3-N及TN去除率;为保障处理效果和降低运行成本,低水温条件下(9~12℃),应提高DO的质量浓度至1.0 mg/L左右。Using A2O-MBR process to treat campus sewage, the effect of it on pollutants removal and the influencing factors were investigated. The results of the test showed that, with the stable operation of the said sys- tem, the effluent water quality was good; however, restricted by carbon source, the TP concentration in the efflu- ent water can＇t meet the discharge standard steadily. Although water temperature had only a little influence on the removal rates of CODCr and NH3-N, the removal rate of TN was affected by it obviously; therefore, with low water temperature, higher removal rates of NH3-N and TN could be obtained when mass concentration of the sludge was maintained at above 6 g/L. In order to ensure good treatment effect and reduce operation cost, the mass con- centration of DO should be enhanced to about l.O mg/L under low water temperature（9~12°C） condition.
