摘要
可渗透反应墙是一种替代抽提技术的创新型地下水原位修复技术。在实际工程中大量不同种类的填料被应用在墙体上,通过吸附、沉淀、氧化还原和生物降解等作用,可处理包括重金属、苯系物、卤代烃、芳香烃、农药以及无机阴离子等污染物。综述了可渗透反应墙的结构、去除污染物机理、优缺点以及活性填料的应用,详细介绍了可渗透反应墙技术的最新研究进展,指出该技术虽已得到广泛认可,但其长期性能尚待实践证明。
Permeable reactive barrier（PRB） is one of the innovative technologies as an alternative to the＆quot;pump and treat＆quot;for in situ remediation of groundwater. In practice, a variety of packing materials have been em-ployed in permeable reactive barrier to remove contaminants such as heavy meatls, BTEX, halogenated hydrocar-bons, aromatic hydrocarbons, pesticides, inorganic anions and so on, through adsorption, precipitation, redox, bio-logical degradation and some other processes. The structure, contaminants-removing mechanism, merits and limi-tations of PRB and application of active packing materials were summarized with the research progress of the said technology introduced in detail also. It was pointed out that, although PRB technology had been wildely acknowl-edged, its long-term performance should be proved through practice.
