| 摘 要： | 针对Et处理量为1500m3的高校中水处理设施，论述了缺氧／好氧-MBR（A／O—MBR）处理工艺运行特性，完成了长效监测及经济性评价。系统MBR池污泥浓度（MLSS）控制在8～12g／L，缺氧池和好氧池水力停留时间（HRT）分别为3h和7h，污泥回流比为200％～300％。当进水COD、总氮、氨氮平均浓度分别为481．3、75．1和65．8mg／L时，出水COD、总氮、氨氮平均浓度分别为16．5、13．4和0．7mg／L，平均去除率分别为96．4％、81．9％和99．0％。在进行化学除磷的情况下，出水总磷的平均浓度为0．8mg／L，平均去除率86．5％。出水水质优于《城市污水再生利用城市杂用水水质》（GB／T18920—2002）中的相应水质指标要求。经济性分析结果显示，该中水站的电耗为0．58kWh／m3。

| Abstract: | An A/O-MBR process with the capacity of 1 500 m3/d was employed aiming at the reclamation of sewage in a university, and the water quality monitoring and economic analysis were conducted in the long- term operation. The MLSS of the MBR was maintained between 8 g/L to 12 g/L. The HRT of the anoxie tank and the aerobic tank was 3 h and 7 h, respectively, and the sludge return ratio was 200% -300%. When the average influent concentration of COD, total nitrogen and ammonia nitrogen were 481.3,75.1 and 65.8 mg/L, respectively, the average effluent concentration of COD, total nitrogen and ammonia nitrogen were 16.5,13.4 and 0. 7 mg/L, and the corresponding removal efficiency were 96.4% , 81.9% and 99.0% , respectively. The chemical phosphorus removal was achieved with the PAC coagulation, the effluent concentration of total phos- phorus was 0.8 mg/L and the average removal efficiency was 86.5%. The water quality is better than that of the National Water Quality Standard for Urban Miscellaneous Water Consumption （GB/T 18920-2002）. The eco- nomic analysis showed that the electicity cost of the systerm is 0.58 kWh/m3. |
