摘　　要：地下水铬污染问题日益突出物理、化学和生物修复技术处理铬污染地下水都具有应用潜力。本文概述了地下水铬污染的来源和潜在影响,并论述了吸附、氧化、还原、离子交换、生物修复等修复技术处理铬污染地下水的机制。提出当前修复铬污染地下水问题需要跨学科的综合方法和创新技术来解决,以现有认知可以证实上述修复技术去除六价铬(Cr(Ⅵ))和三价铬(Cr(Ⅲ))核心技术的应用潜力。此外,也提出了限制各种修复技术发展的瓶颈在于修复成本高和长期稳定性差等,在今后的研究中有必要给予足够的关注,以推动多种修复技术走向应用。The problem of chromium contamination in groundwater is becoming increasingly prominent,and physical,chemical,and biological remediation technologies show promising potential for treating chromium-polluted groundwater.This paper provides an overview of the sources and potential impacts of chromium pollution in groundwater and discusses the mechanisms of remediation techniques such as adsorption,oxidation,reduction,ion exchange,and bioremediation.It is suggested that addressing the current challenges of chromium-contaminated groundwater requires comprehensive interdisciplinary approaches and innovative technologies.Current knowledge substantiates the application potential of these remediation techniques for removing hexavalent chromium(Cr(Ⅵ))and trivalent chromium(Cr(Ⅲ)).Furthermore,this study identifies that the key barriers to the development of various remediation technologies lie in high remediation costs and poor long-term stability.Future research should focus on these issues to facilitate the practical application of diverse remediation technologies.
