摘要: 镉是一种毒性较强的重金属元素,易被动植物吸收富集而产生危害。目前,镉及镉化合物被广泛应用,导致越来越多的土壤被镉等重金属污染,环境问题也变得越来越突出,因而土壤镉污染的防治与修复技术受到诸多学科的高度重视和研究。综述了我国近年来常用的修复技术,如电修复、生物修复等,讨论了不同修复技术的修复机制、应用和优缺点,并对未来重金属修复技术的研究方向进行了展望,旨为镉等重金属修复提供理论依据。

Abstract: Cadmium(Cd)is a strongly toxic heavy metal that can be easily absorbed by plants and accumulated in human body through food chains so that result in health problems. Due to the increasingly wide use of cadmium and its compounds,there come more and more heavy-metal contaminated soil and other environmental problems,therefore the technologies of preventing and remedying cadmium-contaminated soil have attracted much attentions of many researchers in several fields. In this review,we introduce frequently-used remediation technologies in recent years,such as electrochemical-remediation,bioremediation,and so on,and followed a discussion about the mechanisms,applications,advantages and shortcomings of these remediation technologies. Moreover,we prospecte the future development trend of heavy-metal remediation technology,aiming at providing theory supports for the research and development of heavy metal repair.

Key words: cadmium-contaminated soil, electrochemical remediation, in situ fixation, phytoremediation, combined remediation
