Application of ex-situ thermal desorption technology and equipment in contaminated site remediation projects in China

The ex-situ thermal desorption technology has significant advantages such as high removal efficiency, short remediation period and strong application scope, which has been proven to be one of the most effective techniques for organic contaminated sites remediation. This paper introduces the research status at home and abroad, and application situation of ex-situ thermal desorption technology and equipment in China by means of data, literature review and field investigation. Meanwhile, combined with the engineering cases in China, the corresponding technology routes of direct and indirect thermal desorption equipment are analyzed, respectively. The equipment selection recommendations for the practical contaminated site remediation is proposed, as well as the theoretical research and equipment development orientation of thermal desorption technology, which will provide reference for the popularization and application of ex-situ thermal desorption technology in organic contaminated sites remediation in China.
