摘　　要：本文对比了几种修复锑污染土壤的方法,发现固化/稳定化技术是一种成熟有效的处理方法,该技术具有快速、彻底、经济的优点,但存在固化后的锑易被二次活化、后期监测困难、固化后土壤难以二次利用等问题。同时对不同的固化剂、稳定化剂的作用原理进行总结,概述了水泥、石灰/粉煤灰、药剂类对最终修复效果的影响,分析了在土壤理化性质、环境因素影响下锑的再活化行为,提出了应选择高效的试剂、将其与其他修复技术联合使用的研究方向。After comparing several methods for remediation of antimony contaminated soil,it is found that the solidification/stabilization technology is a mature and effective treatment method.This technology has the advantages of fast,thorough and economic.However,there are some problems such as the secondary activation of solidified antimony,difficulties in later monitoring,and difficulties in secondary utilization of solidified soil.At the same time,the action principle of different curing agents and stabilizing agents is summarized,the influence of cement,lime/fly ash and agents on the final remediation effect is summarized,the reactivation behavior of antimony under the influence of soil physical and chemical properties and environmental factors is analyzed,and the research direction of selecting efficient agents and using them together with other remediation technologies is proposed.
