沿江某城市建成区污水处理系统问题分析及对策研究

Problems Analysis and Countermeasures Investigation of Sewage Treatment System in a Built-up Area of a City along the Yangtze River

以沿江某城市建成区污水收集及处理系统为例,通过水质和水量的定性定量分析、管网排查检测、现场踏勘等方法,探究外水类型及占比,分析污水收集及处理系统中的污染物沿程浓度变化。因地制宜,从“挤外水”角度提出提质增效对策措施,提高污水处理系统进水污染物浓度,促进该沿江城市建成区污水收集及处理系统的提质增效,加快推进区域水环境的质量改善。

Taking the sewage collection and treatment system in the urban built-up area along the Yangtze River as an example,various methods including qualitative and quantitative analysis of water quality and quantity,pipeline network detection and site survey were adopted.The type and proportion of external water and the variations of contaminants concentration in sewage collection and treatment system along the way were analyzed.According to local conditions,the countermeasures of improving quality and increasing efficiency are put forward from the perspective of“squeezing the external water”,including increasing the concentration of pollutants in the sewage treatment system,promoting the quality and efficiency of the sewage collection and treatment system in the built-up area of a city along the Yangtze River,and accelerating the improvement of the quality of the regional water environment.
