负压排水技术在河道截污工程中的应用

Application of Negative Pressure Drainage Technology in River Sewage Interception Project

2021年12月31日,国家发展和改革委员会印发了《“十四五”重点流域水环境综合治理规划》,为持续做好重点流域水环境综合治理指明了方向。作为水环境治理的重要一环,河道截污工程所处环境往往较为复杂,传统模式无论从经济性还是从技术可行性方面都无法有效实现。本文基于我国河道截污工程现状,分析负压排水技术在河道截污工程中的应用,并结合实际案例进行论证,为国内河道截污工程的实施提供借鉴。

On December 31,2021,the National Development and Reform Commission issued the "14th Five-Year Plan for Comprehensive Water Environment Management of Key River Basins",which pointed out the direction for the continuous improvement of the comprehensive water environment management of key river basins.As an important part of water environment governance,the environment in which river sewage interception projects are located is often complex,and the traditional model cannot be effectively realized in terms of economics and technical feasibility.Based on the current situation of river sewage interception projects in China,this paper analyzes the application of negative pressure drainage technology in river sewage interception projects,and demonstrates it in combination with actual cases,so as to provide reference for the implementation of domestic river sewage interception projects.
