大型截污渠箱在广州某黑臭水体整治工程中的应用

Application of Large Sewage Interception Underdrain in Black and Stinky Water Reclamation Project

城市黑臭水体治理的关键是实现流域范围内彻底"控源截污"。广州均禾涌大型截污渠箱工程是"控源截污"的典型案例,通过在河底设置大型截污渠箱,彻底截流旱季污水及初期雨水,减轻水体污染,提升河涌水质。通过对该工程污染源的调查及水量分析,介绍了截污渠箱及其入流井的具体布置方式,以供其他工程参考。

A comprehensive implementation of the ＂Water Pollution Source Control＂ at the watershed level is the key to the black and stinky water reclamation project. The large sewage interception underdrain project on the Junhe River is a typical project of ＂Water Pollution Source Control＂. The sewage and the initial rainwater are intercepted thoroughly by planting large sewage interception underdrain in the bottom of the river. Through the investigation of the pollution sources and the analysis of the water quantity in this project, the layout of the large underdrain and its inflow well was introduced. The experience of this project could provide reference for other projects.
