摘要：

铁渗透反应格栅技术修复地下水中氯代烃，尤其是四氯乙烯和三氯乙烯，已日臻成熟；近年，研究者对该技术的关注已集中到影响格栅长期运行性能的因素上。文章从地下水的常量化学组分、铁表面形成的矿物沉淀、铁渗透反应格栅中的微生物和共存有机污染物4个方面，对影响其长期运行性能的因素进行了综述。分析表明，铁表面矿物的长期积累是降低格栅长期运行性能的主要因素,并对该技术的发展进行了展望。

Abstract:

Ironbased permeable reactive barriers (Fe0PRBs) for insitu groundwater remediation of chlorinated hydrocarbons such as perchloroethylene and trichloroethylene have become a mature technology. Results published recently focus on the evaluation of longterm performance of Fe0PRBs. This paper reviews the factors impacting on the longterm performance of Fe0PRBs in treating chlorinated solvents, including groundwater chemistry, mineral precipitates formed on iron surface, microbes within Fe0PRBs and other coexistent organic pollutants. It is mineral precipitates accumulating within Fe0PRBs that become the predominant factor to decrease barriers reactivity over time. Moreover, future research on multimedia permeable reactive barriers and sequential ones based on Fe0PRBs have been recommended.

Key words: granular iron, groundwater remediation, chlorinated hydrocarbon, permeable reactive barrier (PRB), longterm performance
