摘　　要：为保证廊坊市龙河出境断面水质稳定达标、改善河道水环境质量,建立以水平潜流+表面流组合人工湿地工艺为核心的处理系统,阐述了工艺设计要点,并对污染物去除效果进行分析。运行结果显示,该处理系统对河水中COD、NH_(3-)N和TP的去除率平均值分别为45.3%、54.2%和64.8%,使出水水质能够稳定达到《地表水环境质量标准》(GB 3838-2002)Ⅴ类水体标准。In order to ensure that the water quality of Longhe River exit section in Langfang city is stably up to standard,and to improve the water environment,a treatment process based on the combination of horizontal subsurface flow constructed wetland and surface flow constructed wetland was established.Design points of the process were introduced,and performances of the system were analyzed.Results showed that the average of removal efficiency of COD,NH_(3-)N and TP were 45.3%,54.2%and 64.8%respectively,which could ensure that the water quality of the effluent meet V level of Environmental quality standards for surface water(GB 3838-2002)stably.
