地下水渗透反应格栅技术发展综述

Permeable Reactive Barrier for Groundwater Pollution Remediation: An Overview

面对日益严重的地下水污染,地下水渗透反应格栅技术作为一种原位、简易、被动技术在地下水污染修复中被广泛研究和应用。依据渗透反应格栅技术的定义及发展历程,渗透反应格栅技术的发展大致可以分为2个阶段,即2000年以前的传统零价铁渗透反应格栅阶段和2000年以后的新型复合介质渗透反应格栅阶段。伴随地下水污染形势的日益复杂化,以及渗透反应格栅技术的不断应用和材料科学等其他学科的飞速发展,未来渗透反应格栅技术的发展将主要集中于复合介质与新介质的开发、组合式渗透反应格栅技术的研发、渗透反应格栅技术与其他修复技术的联用以及渗透反应格栅工程的长期监测及管理。

As an in situ, simple and passive technology, Permeable Reactive Barrier （PRB） is becoming widely used in groundwater remediation. Based on its definition and development process, the development of PRB can be divided into two stages： The traditional zero-valent iron PRB before 2000 and the PRB composed of novel mixed media after 2000. With the rapid worsening of groundwater pollution, the increasing application of PRB and the rapid development of materials science, the development of PRB technology in future will be mainly focused on the investigation of mixed and novel media, the design of mixed PRBs, the combination of PRB technology with other remediation technology, and the long-term monitoring and management of PRB projects.
