摘　　要：新桥河是长湖的重要二级支流,其上游骏马工业园污水处理厂处理后尾水和附近居民的生活污水汇入,导致水质不能稳定达到Ⅲ类水质,属于受损河流,亟须在截污、清淤的基础上开展生态修复。在调研收集资料基础上,核算新桥河进入湿地水量,科学比选设计方案,采用垂直潜流人工湿地,并在前段布置高效沉淀池预处理,设计处理规模为2.0万m^(3)/d,出水水质满足《地表水环境质量标准》(GB 3838-2002)Ⅲ类标准,能有效削减污染物入湖总量,恢复河湖生态系统。新桥河复合人工湿地工程可以为平原湖区小流域生态修复提供有益的借鉴。Xinqiao River is an important secondary tributary of Changhu Lake.The tail water treated by the sewage treatment plant of Junma Industrial Park and the domestic sewage from nearby residents are imported into Xinqiao River upstream,which leads to the water quality cannot be stable to reach class iii water quality,belonging to damaged rivers.It is urgent to carry out ecological restoration on the basis of pollution interception and silt removal.On the basis of investigation and data collection,the water volume of Xinqiao River entering the wetland was calculated.Scientific selection of design schemes,and the vertical subsurface flow constructed wetland was adopted,and the high efficiency sedimentation tank was arranged in the front section for pretreatment.The designed treatment scale was 20000 m^(3)/d,and the effluent water quality met the class Ⅲ standard of Surface Water Environmental Quality Standard(GB3838-2002),effectively reducing the total amount of pollutants into the lake,and restoring the river and lake ecosystem.The Xinqiao River composite artificial wetland project can provide useful reference for ecological restoration of small watersheds in plain lake areas.
