关于封闭独立小微水体水质改善的设计探讨——以闵行区华漕镇北杜巷宅河为例

Discussion on Design of Water Quality Improvement of Closed and Independent Small and Micro Water Bodies

为解决小微水体黑臭污染问题,工程设计中须考虑综合整治措施。结合上海地区某工程实例,整体分析污染原因,梳理整治思路。根据水体自身特点,总结分析治理措施,结合后期监测数据验证治理成效,完善小微水体整治研究。该类水体整治应从控源截污入手,结合底泥疏浚、水系调度或沟通、水体形态优化、构建生态驳岸、水生态系统构建等,达到较理想的效果。

To solve the problem of small and micro water black-odor pollution, the comprehensive treatment measures must be considered in the engineering design. Taking Beiduxiangzhai River in Huacao Town of Minhang District as an engineering example, this paper analyzes the pollution causes and sorts out the treatment ideas. Based on the features of water body, this paper summarizes and analyzes the treatment measures. Combined with the late monitoring data, the treatment efficiency is verified, and the study of small and micro water treatment is perfected. This kind of water treatment should start with controlling the sources and intercepting the pollution. Combined with the dredging of sediment, scheduling or communication of water system, shape optimization of water body, building of ecological revetment and construction of water ecosystem, the ideal result is achieved.
