  • 摘要: 针对日处理量为1 500 m3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8~12 g/L,缺氧池和好氧池水力停留时间(HRT)分别为3 h和7 h,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65.8 mg/L时,出水COD、总氮、氨氮平均浓度分别为16.5、13.4和0.7 mg/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0.8 mg/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/T 18920-2002)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0.58 kWh/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 anoxic 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 phosphorus 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 economic analysis showed that the electicity cost of the systerm is 0.58 kWh/m3.
