山区县污水系统问题成因与治理路径研究

Research on the Problems Causes and Treatment Paths of Sewage System in Mountain County

为了落实生态环境部、住房和城乡建设部的行动计划部署,恢复城镇污水处理系统功能,改善城镇水环境质量,进一步提升设施整体污染收集、处理和减排效果,通过查阅文献、实地踏勘、调查以及工程案例研究,从前期方案、施工建设、管理协调和养护水平4个维度分析了山区县污水系统运行低效的典型原因,并从系统完善、片区衔接、初期雨水处理、溢流污染控制和运营维护5个方面制定了相应的治理路径。为山区县特别是沿江地区以合流制为主的污水系统提质增效工作提供了一种新的思路。

In order to implement the action plan and deployment of the Ministry of Ecology and Environment and the Ministry of Housing and Urban-Rural Development, restore the functions of the urban sewage treatment system,improve the quality of the urban water environment, and further enhance the overall pollution collection, treatment and emission reduction effects of the facilities, literature review, field survey, investigation and project case studies are carried out. T typical causes of inefficient operation of sewage system in mountain counties are analyzed from four dimensions of preliminary scheme, construction, management coordination and maintenance level in the paper. The corresponding treatment paths are determined from five aspects of system improvement, area connection, initial rainwater treatment, overflow pollution control and operation and maintenance. It provides a new idea for improving the quality and efficiency of sewage system based on confluence system in mountainous counties, especially riverside areas.
