摘要:

尽管赤泥在重金属污染环境修复研究中的应用越来越受到重视,但赤泥给污染环境修复带来突破的同时也给环境带来风险。目前,在赤泥的重金属环境修复研究中,针对赤泥的修复效果和修复过程研究较多,而对赤泥的钝化机理研究不够深入,赤泥修复的环境安全风险评价才刚起步。本文对近年来国内外关于赤泥修复重金属污染的研究进行综述,并指出了赤泥在今后的重金属污染治理中应加强的方向:一是深入赤泥对重金属钝化机制的研究;二是探索有效的赤泥安全评价方法;三是联合赤泥修复和生物修复技术(植物和微生物)对重金属和有机物复合污染进行修复。

Abstract: The application of red mud in the remediation of heavy metals-polluted environment has raised great concerns. This application does make a breakthrough in the remediation of heavy metals-polluted environment, but brings about environmental risks at the same time. In the present studies on the application of red mud in the remediation of heavy metalspolluted environment, more attentions focus on the remediation effectiveness or remediation process, but few focuses on the deactivation mechanisms of heavy metals by red mud. The environmental riskassessment of red mud remediation is still at the beginning. This paper reviewed the research progress in the application of red mud in the remediation of heavy metalspolluted environment, and gave comments to the future studies on the application of red mud in the management of heavy metals pollution: 1) to further study the deactivation mechanisms of heavy metals by red mud, 2) to approach the effective safety assessment means of red mud application, and 3) to integrate the red mud remediation and bio-remediation (plants or microorganisms) to remediate the heavy metals and organic compound pollution.
