摘　　要：再生水回用于河道是缓解水资源短缺与地下水位下降的一种有效措施,但由于再生水成分复杂,长期回用可能会对河道水体和地下水环境产生影响。以典型再生水回用区--北京潮白河顺义段为例,综述再生水回用对地表水环境的影响,及长期入渗对地下水中溶解盐类、氮素、微量有机物、微生物群落与功能的影响,以期为类似再生水回用工程提供经验。The reuse of reclaimed water to replenish rivers is considered to be an effective measure to alleviate water shortage and groundwater level decline.However,due to the complexity of reclaimed water,long-term recharge may have an impact on the river and groundwater environment.The Shunyi section of Chaobai River,a typical reclaimed water recharge area in Beijing,was selected as an example to summarize the impact of reclaimed water recharge on the surface water environment.In addition,the effects of long-term infiltration on dissolved salts,nitrogen,trace organic matter,microbial community and function in groundwater were studied,which provide experience for similar reclaimed water recharge projects.
