摘　　要：我国地下水重金属污染在空间、种类等方面具有广泛性、多样性,其危害具有复杂性、长期性,亟需发展和推广经济实用且环境友好型修复技术。可渗透反应墙(Permeable Reactive Barrier,PRB)技术被认为是最有潜力的地下水处理技术之一,具有效率高、成本低、安装简单、环境干扰小等优点,作用关键在于其反应介质的特性。本文归纳总结了反应介质的分类组合及作用机理,并整合目前国内外PRB的应用情况,为反应介质的研发、PRB技术的工程应用提供重要参考。Heavy metal contamination in groundwater in China is extensive and diverse in terms of space and type, and its hazards are complex and long-term, so there is an urgent need to develop and promote economical, practical and environmentally friendly remediation technologies.The permeable reaction barrier(PRB) technology is considered one of the most promising groundwater treatment technologies, with the advantages of high efficiency, low cost, simple installation and low environmental disturbance, the key to its role lies in the characteristics of its reaction medium. This paper summarizes the classification combination and action mechanism of reaction media, and integrates the current application of PRB at home and abroad to provide an important reference for the research and development of reaction media and the engineering application of PRB technology.
