Thermal desorption (TD) is a mainstream technology for the remediation of organic compound-contaminated soil. By reviewing the domestic and foreign research on the remediation of organic compound-contaminated soil by TD, this paper systematically introduces the principle, characteristics, and classification of TD. The impact of key operating parameters (such as heating temperature and heating time), certain physical and chemical properties (such as soil texture, moisture content), and external conditions (such as additives and the carrier gas) on the TD process is summarized. Next, pollutants’ migration and their transformation processes, as well as the laws governing the TD process, are briefly described. Finally, the prospects of TD, in terms of its future research and development directions, are described, with the aim of providing references for the application and promotion of TD.

热脱附（TD）是用于修复受有机化合物污染的土壤的主流技术。通过对国内外有关TD修复有机化合物污染土壤的研究进行综述，系统地介绍了TD的原理，特点和分类。总结了关键操作参数（例如加热温度和加热时间），某些物理和化学性质（例如土壤质地，水分含量）以及外部条件（例如添加剂和载气）对TD工艺的影响。接下来，简要描述污染物的迁移及其转化过程，以及控制TD过程的法律。最后，就TD的未来研究和发展方向描述了TD的前景，
