镇江虹桥港上游黑臭水体系统性治理工程设计

Project Design of Systematic Treatment of Black-smelly Water Body in Upstream of Hongqiaogang,Zhenjiang City

针对镇江虹桥港源头黑臭水体治理需求,开展了虹桥港服务范围系统性综合整治工程建设,运用海绵城市建设理念,提出了源头低影响开发(LID)改造、过程管网转输调蓄和末端灰绿蓝生态处理的系统性治理方案,并进行了相应工程设计。详述了工程运行工况模式、主要处理设施和构筑物的设计参数以及工艺特点。工程完成后河道源头黑臭消除,河道主要水质指标达到了地表水Ⅳ类标准,片区实现了水安全、水环境、水生态和水景观的综合提升。

In order to treat black-smelly water body,the systematic comprehensive treatment project was constructed in Zhenjiang Hongqiaogang.Based on sponge city idea,the systematic treatment scheme was elaborated induding source low impact development(LID),process transmission and storage of pipe network and end treatment with gray-green-blue infrastructure.The project operation mode,treatment facilities,design parameters of each unit and process design characteristics were described in detail.As a result,the black-smelly water issue was solved and the key water quality indexes met the class Ⅳ surface water standard,which improved comprehensive benefits of water safety,water environment,water ecology and water landscape.
