摘　　要：通过对北京市目前运行的4种典型再生水处理工艺中的主要处理单元出水水质进行监测,得到各种再生水处理工艺对主要水质指标的去除情况。结果表明,4种再生水处理工艺出水基本能满足设计及使用要求;TN和NH3—N浓度仍然是影响多数再生水厂最终出水水质的限制性指标;再生水用于地下水回灌时水质要求较高,尤其是其中的"井灌"对水质要求很高,一般的沉淀过滤、超滤及MBR工艺较难满足要求。We got the main water quality removal efficiencies of the four typical wastewater reclamation processes running in Beijing by monitoring the effluents of the main treating units.The results showed that effluents of the four wastewater reclamation processes can meet the design and use requirement basically.TN and NH3—N are still the limited items to final effluent qualities of the water reclamation plants.The reclaimed water quality is required more strictly when it is used for groundwater recharge,especially for injection recharge,and normal filtration and MBR processes are very difficult to meet it.
