摘要: 钒是典型的氧化还原敏感元素,其在地壳中储量丰富,又是现代工业中性能优异的催化剂. 由于地质风化作用及密集的开采、冶炼、应用等人类活动,导致土壤地下水钒污染日益严重,引起研究者的广泛关注. 从物理法、化学法和生物法3个方面,综述了土壤地下水钒污染修复技术的最新研究进展. 物理法主要包括改土法和电解法,化学法主要包括化学淋洗、化学吸附及化学还原固定,生物法主要包括植物修复和微生物修复. 同时展望了钒污染土壤地下水修复技术的发展趋势,为后续研究提供参考.Abstract: Vanadium is a typical redox-sensitive element that is abundant in the crust and is a superior catalyst in modern industry. Due to the geological weathering and intensive human activities such as mining, smelting and applications, vanadium pollution in soil and groundwater is becoming more and more serious, arousing widespread concern of researchers. This article reviews the latest research progress of remediation of vanadium contamination in soil and groundwater from three aspects: physical methods, chemical methods and biological methods. Physical methods include soil replacement and electrolysis. Chemical methods include chemical leaching, chemical adsorption and chemical reduction immobilization. Biological methods include phytoremediation and microbial remediation. Meanwhile, the trend of the development in remediation technology of vanadium contaminated soil and groundwater is also forecasted, which will provide reference for subsequent researches.
