摘　　要：九江市十里河是中心城区的一条重要内河,整治前水体污染较为严重,下游7.20 km河道被确定为黑臭水体。十里河水环境系统综合治理工程以控源截污、内源治理、生态修复、活水提质为主要措施,通过源头小区改造、二级管网及截污管新建及修复、调蓄池建设、污水处理厂建设、生态清淤、水生态系统构建、补水活水等工程措施的实施,十里河黑臭现象全面消除,氨氮、化学需氧量、溶解氧等主要水质指标已达到地表水Ⅳ类标准。此外,本工程实施后,小区污水系统出口COD浓度明显提升,污水处理能力大幅提高,生态效益充分显现,取得了良好的环境效益和社会效益。Shili River is an important inland river in downtown Jiujiang.Before remediation,the river was seriously polluted,and 7.20 km downstream river was determined as a black and odorous water body.The comprehensive treatment project of Shili River water environment mainly included source control,sewage interception,internal source control,ecological remediation and ecological water compensation.The black and odorous water was completely eliminated in Shili River through reconstruction of source community,construction and repair of the secondary pipe network and sewage interceptor sewer,construction of regulation and storage tank,construction of sewage treatment plant,ecological desilting,construction of water ecosystem,ecological water compensation and other engineering measures,and the main water quality indicators such as ammonia nitrogen,COD and DO all reached the classⅣsurface water standards.In addition,after the implementation of the project,COD at the outlet of the community sewage system increased significantly,the sewage treatment capacity increased greatly,the ecological benefits fully displayed,and good environmental and social benefits were achieved.
