摘要: 对海绵城市建设中城市人工湿地的设计方法进行研究,表征海绵城市建设中人工湿地所发挥的净化雨水的重要作用。当改建项目人工湿地的处理能力低于设计水量时,应在湿地前端增设强化处理设施,以达到削减污染负荷、降低SS、减少湿地堵塞及雨水深度净化的要求;人工湿地工程前置强化处理设施、稳定塘、潜流湿地、表流湿地、出水池等各工艺段经过内部结构设计和合理优化,能够有效削减海绵城市建设中雨水污染负荷;人工湿地出水水质随泵站雨水负荷变化,呈现水质不稳定的特点,为此建议适当降低雨水处理量的措施,确保达标排放。

Abstract: This paper studies the design method of urban constructed wetlands in sponge city construction,characterizing the important role of constructed wetlands in purifying rainwater in sponge city construction. When the treatment capacity of the constructed wetland in the renovation project is lower than the designed water volume,enhanced treatment facilities should be added at the front end of the wetland to meet the requirements of reducing pollution load,reducing SS,reducing wetland blockage,and deep rainwater purification. After internal structural design and reasonable optimization of various process sections such as pre-enhanced treatment facilities,stabilization ponds,subsurface wetlands,surface flow wetlands,and outlet ponds,constructed wetland projects could effectively reduce the rainwater pollution load in sponge city construction. The effluent quality of constructed wetlands varies with the rainwater load of the pumping station,showing the characteristics of unstable water quality. It is recommended to take appropriate measures to reduce the rainwater treatment capacity to ensure compliance with discharge standards.
