摘    要:将A2/O生物处理单元与MBR相结合构建了的处理能力为2 000 m3/d的A2/O-MBR工艺,并应用于缺水地区校园生活污水的处理与回用。该系统运行稳定,运行阶段的实验结果表明,在进水COD为100~200 mg/L、NH4+-N为19~33 mg/L、TN为25~43 mg/L、TP为3~5 mg/L和低碳氮比的情况下,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) 的要求,且全部用于杂用及校园绿化等。经分析该工艺运行成本为0.96 元/m3,每年可节省自来水73万t,获得较好的环境效益与经济效益。

关 键 词:A2/O-MBR工艺|低负荷|校园生活污水|运行成本

Abstract:A2/O-MBR combined process was developed for campus wastewater treatment and reuse with the treatment capability of 2 000 m3/d. Water quality analysis was conducted during steady operation period, and the experimental results indicated that the A2/O-MBR combined process showed good performance in campus wastewater treatment. Though the influent concentrations of COD, NH4+-N, TN and TP were in the range of 100~200 mg/L, 19~33 mg/L, 25~43 mg/L and 3~5 mg/L, respectively, and the C/N ratio of influent was very low, the effluent quality was superior to the requirements of Water Quality Standard for Urban Miscellaneous Water Consumption (GB 18920-2002). All the effluent was reused for toilet flushing, gardening, and so on. By running cost analysis, it was found that the running cost of this combined process was about 0.96 yuan/m3 and each year about 730 000 tons of drinking water could be saved. The system brought excellent environmental and economic benefits.
Keywords:A2/O-MBR process|low loading|campus wastewater|running cost
