Abstract

Soil remediation has become a hotspot in China. There are many researches on soil thermal remediation but little attention has been paid to the change of soil property during thermal remediation. This paper compares eight typical soil thermal repair technologies and analyzes each thermal repair technology in terms of target pollutants and costs. Then, from the perspective of sustainable repair, it discusses innovative thermal repair technology. Effects on soil properties such as soil pH, organic matter, mineral structure, biological structure, vegetation, secondary pollution, etc. are analyzed. Next an in-depth approach to soil reuse after thermal repair is explored. In the end, suggestions are given to the thermal repair technologies and soil reuse after remediation so as to provide a certain theoretical basis for sustainable application of thermal repair technology.
