摘　　要：城市污水再生处理反渗透(mWRRO)系统RO浓水中除了含有常规化学污染物外,还存在危害人类健康和生态环境的难生物降解有机物和高风险有毒有害物质。针对mWRRO系统RO浓水水质特征,系统总结和分析了mWRRO系统RO浓水的中间处理、循环处理、厂外排放处理和直接排放处理4种处理方式,详细论述了各处理方式的适用条件、处理目标、控制方法和目前已报道的处理技术。并根据mWRRO的工艺特征,提出了中间处理与循环处理相结合的mWRRO系统RO浓水的综合处理模式。Except the common chemical pollutants, there are persistent organic pollutants and high-risk toxic substances, which are threats to human health and ecological environment, in the concentrated wastewater from the municipal wastewater reclamation reverse osmosis （mWRRO） system. Based on the characteristics of concentrated wastewater from mWRRO, this paper summa- rized and analyzed its four processing modes including intermediate treatment, recycle treatment, outside WRP （wastewater reclamation plant） treatment and direct discharge treatment. The appli- cable condition, removal target, control method and corresponding treatment technology of the four modes were also analyzed and presented. In addition, this paper put forward a comprehensive RO concentrate treatment model by combining intermediate treatment with recycle treatment, under the technological characteristics of mWRRO process.
