Abstract:has advantages such as no need to excavate and transport soil, high equipment mobility and short reme⁃diation cycle. Previous research focused on the repair effect and influencing factors of in-situ thermaldesorption. However, the research on repair mechanism and removal path was more conducive toprocess optimization. The occurrence characteristics and influencing factors of organic pollutantsin soilwere introduced. The desorption mechanism of organic pollutants during soil heating was analyzed. Thetreatment process of organic pollutants,which was transferred to tail gas,was discussed, and some sug⁃gestions for further application research were put forward. Close-
