海绵城市背景下的城市污水处理问题及技术发展分析——以二沉池为例

Urban Sewage Treatment Issues and Technological Development Analysis under the Background of Sponge City:Taking Secondary Sedimentation Tanks as an Example

从海绵城市背景出发,对城市污水处理的概况和发展进行概括与分析。对城市污水处理存在的总体性问题进行阐述,因处理系统的复杂性,选取污水处理环节中的二沉池作为研究对象,对其存在的问题以及未来展望进行分析研究。以二沉池的研究成果作为参考,引申出对未来城市污水处理的技术展望和发展,以期为城市水资源管理与利用提供经验和建议。

Starting from the background of sponge cities,this paper provides an overview and analysis of the development of urban sewage treatment.It elaborates on the overall problems existing in urban sewage treatment and selects the secondary sedimentation tank as a research object due to the complexity of the treatment system.The problems and future prospects of the secondary sedimentation tank are analyzed.Taking the research results of the secondary sedimentation tank as a reference,this paper extends to the technological outlook and development of future urban sewage treatment,aiming to provide experience and suggestions for urban water resource management and utilization.
