可渗透反应栅(墙)技术综述

A review of permeable reactive barrier technologies

为了促进可渗透反应栅(墙)PRB技术在我国地下水修复领域的应用和发展,对PRB技术进行简要综述,包括PRB类型、原理,污染羽流的类型和污染方式,设计和安装PRB之前勘察的内容,反应介质材料类型的介绍和选择等,PRB的设计与施工、后期的维护与监测,并对PRB技术的经济性进行评价与分析。提出我国在研究PRB技术时,不应局限于研究反应介质,还应考虑前期勘察、结构、运行监测等方面的因素,并选择合理的地下水修复投融资方式和途径。

In order to promote the application of permeable reactive barrier（PRB） technologies to groundwater remediation in China,this paper presents a brief review of PRB technologies,including the types and concept of PRB,the types of contaminant plumes and ways of contamination,the investigated items before design and installation of PRB,the introduction to and selection of material types of the reaction medium,and design and construction of PRB and post-maintenance and monitoring.Moreover,the economics of PRB technologies is evaluated and analyzed.It is pointed out that research focuses should be placed not only on the reaction medium,but also on pre-investigation,structure,monitoring,and reasonable investment and financing policies for groundwater remediation.
