摘要
零价铁可渗活性栅(Fe0-PRB)技术,被证明是一项修复由卤代烃、卤代芳烃和有机氯农药以及一些有毒金属(如铬、硒、铀、砷和锝等)引起的土壤及地下水污染的有效技术。本文介绍了零价铁还原脱氯的机理以及影响反应速率的因素;进一步讨论了国内外利用零价铁修复受污染土壤及地下水的研究现状和发展趋势。
The Fe^0 Permeable Reactive Barrier （PRB） is an effective technology for the remediation of soil and groundwater contaminated by chlorinated hydrocarbons, chlorinated aromatic hydrocarbons, chlorinated pesticides and toxic metals such as chromium,selenium, uranium, arsenic and technetium. The reduction of chlorinated compound by zero-valent iron was discussed on the mechanism and the effects of the dechlorlnated rate, as well as the study and progress of the remediation thchnics contaminated soil and groundwater using zero-valent iron.
