摘　　要：介绍了倒置A2/O+MBR工艺处理矿区生活污水工程的设计与调试,考察了工艺的运行特性、膜污染控制方法及效果。结果表明,倒置A2/O+MBR工艺处理生活污水的效果稳定高效,抗冲击负荷能力强,出水COD、SS、NH3-N、TN、TP、BOD5等主要水质指标可达到和优于国家城镇污水处理厂污染物排放标准(GB 18918-2002)一级A标准;MLSS质量浓度在9 000 mg/L以下,保持SRT为30 d条件下,在线清洗和体外化学清洗可保证污水处理系统的正常稳定运行。倒置A2/O+MBR工艺处理矿区生活污水具有较大的适用性,可大规模推广应用。Here we introduced the design and operation of the reversed A^2/O combined MBR （A^2/O-MBR） process for treatment of domestic sewage in a mining area. The operating characteristic of this process, control methods and effect of membrane fouling were also investigated. The results showed that the performance of the A^2/O-MBR process was stable, efficient and with strong resista ce to impact load. The quality of effluent （COD,SS,NH3-N,TN,TP,BODs） met or better than the national standard class 1A criteria specified in discharge standard of pollutants for municipal wastewater treatment plant （GB 18918-- 2002）. When the MLSS〈9 000 mg/L and SRT=30 d, on-line cleaning and in vitro chemical cleaning can guarantee the normal and stable operation of A^2/O-MBR system. It is shown that the A^2/O-MBR process is a promising technology to be applied in treatment of the domestic sewage in the mining area.
