摘　　要：重金属污染土壤的修复是一项长期而艰巨的任务。作为化学修复的一种,钝化技术成本低、高效省时,而被广泛应用。从石灰性物质、含磷材料、黏土矿物、生物炭、其他材料五大方面归纳了钝化修复的种类,并介绍了钝化修复的作用机制,最后分析了钝化剂修复土壤中重金属的影响因素——钝化剂的投加量、pH、钝化剂的稳定性。基于目前研究现状以及钝化修复存在的问题,对钝化修复今后的发展趋势进行了展望。Remediation of heavy metal contaminated soil is a long-term and arduous task.At present,soil heavy metal pollution remediation technology is mainly divided into physical remediation,chemical remediation and bioremediation.As a kind of chemical repair,passivation technology is widely used because of its low cost,high efficiency and time saving.This paper summarizes the types of passivation remediation from five aspects:calcareous materials,phosphorus-containing materials,clay minerals,biochar and other materials,and introduces the mechanism of passivation remediation.Finally,it analyzes the influencing factors of passivation remediation of heavy metals in soil-the dosage of passivation agent,pH value and the stability of passivation agent.Based on current research status and problems of passivation repair,the future development trend of passivation repair was prospected.
