摘　　要：热脱附技术是修复持久性有机物污染土壤最有效的技术之一。由于其修复周期短、效率高、适用范围广等特点,受到了广泛的关注。本文综述了热脱附技术处理持久性有机物污染土壤的研究进展,就国内外学者的研究现状总结了热脱附技术的影响因素、尾气处置以及工程应用。针对目前热脱附过程能耗高、传统尾气净化方式处置不完全的问题,未来的研究方向应聚焦在多种修复方式协同热脱附以降低能耗、提高效率,采用新型尾气处置方式促进气态污染物的去除,实现持久性有机污染物的全过程控制。Thermal desorption is one of the most effective technologies for remediation of soil contaminated by persistent organic pollutants.Because of its short repair cycle,high efficiency and wide range of application,it has received extensive attentions.In this paper,the research progress of thermal desorption technology in the treatment of persistent organic pollutants contaminated soil is reviewed,and the influence factors,tail gas treatment and engineering application of thermal desorption are summarized based on the research status of domestic and foreign scholars.In view of the current problems of high energy consumption in the thermal desorption process and incomplete disposal of the traditional tail gas purification method,the future research should focus on the synergetic thermal desorption of multiple remediation methods for reducing energy consumption and improving efficiency,and on the new tail gas treatment methods to for promoting the removal of gaseous pollutants and realizing the whole-process control of persistent organic pollutants.
