昆山珠泾中心河黑臭河道的系统施治设计与应用效果

Design and Application Effect of Systematic Treatment of Black and Odorous River in Zhujing Central River,Kunshan

河道是一个生态系统,黑臭河道的根治需要进行系统施治,不仅要考虑河道本身,更重要的是考虑河道汇水区各种污染来源。针对城市河道黑臭现象严重及内涝问题,设计开发了"控源+生态治理"的模式对河道进行生态修复治理。这种系统施治思维已在昆山珠泾中心河得以实施,最终实现河道水体主要指标稳定达到《地表水环境质量标准》(GB 3838—2002)Ⅳ类水标准,同时缓解了河道周边的内涝问题。

The river channel is an ecological system.The remediation of black and odorous river requires holistic treatment,not only considering the channel itself,but also considering various pollution sources in its catchment area.Aiming at the serious black and odor phenomenon and urban flooding problems in rivers,the mode of source control,ecological management was designed and developed to carry out ecological restoration and treatment of channels.The idea has been implemented in Kunshan Zhujing Central River.Finally,the main indicators of river water quality stably reach level Ⅳ of Environmental Quality Standards for Surface Water( GB 3838-2002).At the same time,it relieves flooding problem of the catchment area.
