可渗透反应墙的研究与发展现状

Research and Development Status of Permeable Reactive Barrier

原位修复技术可渗透反应墙(Permeable Reactive Barrier,PRB),不仅经济有效、节约土地资源,而且对环境干扰小,不占用地面空间,可以实现地下水的持续原位修复,因此,有着良好的应用前景。综述了PRB的结构类型;介绍了PRB的国内外研究现状;零价铁PRB去除污染物的作用效果及机理;同时也分析了目前PRB存在的一些问题,对可渗透反应墙未来的发展方向进行了展望。

Permeable Reactive Barrier(PRB)as a in-situ remediation technology,which is not only cost-effective,saves land resources,but also has little interference to the environment,it does not occupy the ground space,and can achieve continuous in-situ remediation of groundwater.Therefore,it has a good application prospect.This paper reviewed the structure types of PRB,introduced the development of PRB at home and abroad,the removal effect and mechanism of pollutants by zero-valent iron PRB,and also analyzed the current problems exist of PRB,and the future development direction of the permeable reactive barrier was put forward.
