Progress in fundamental research on thermal desorption remediation of organic compound-contaminated soil

摘要

Abstract 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.
