珠三角城市流域水环境治理思路与勘察设计关键技术探讨

针对珠三角城市流域水环境治理,以珠海市前山河流域水环境综合治理工程为研究实例,分析探讨了流域治理思路和水环境治理勘察设计的部分关键技术.珠三角城市流域治理以流域本底情况为根本依据,综合治理措施以“控源、截污、清淤、补水、修复”为主;流域治理以污水收集处理完善为核心,提升管网摸查与成图设计效率,精准设计管道关键接驳节点,...

Discussion on Management Idea and Key Technology of Investigation and Design in Urban Watershed of Pearl River Delta

Aiming at the water environment management of the Pearl River Delta city basin,taking the Qianshan River Basin water environment comprehensive management project in Zhuhai city as an example,this paper analyzed and discussed the watershed management ideas and some key technologies of water environment management survey and design.The urban watershed management of the Pearl River Delta was based on the background of the watershed,and the comprehensive control measures were mainly"source control,interception,dredging,water replenishment and restoration".The watershed management was focus on the improvement of sewage collection and treatment,and the efficiency of checking and mapping of pipeline network should be improved,the key connection nodes of the pipeline should be accurately designed.,and the appropriate status quo network management and repair technology should be adopted to ensure the effectiveness of the implementation of urban watershed management.
