| Abstract: | Nowadays, the soil contamination from heavy metals, e.g. Hg, has become one of the most important environmental issues. In order to remove Hg from the soil and fulfill the requirements of industrial or agriculture use, numerous measures were proposed. Thermal desorption among them is paid much attention due to some unique advantages. The paper describes the system layout and general working principle of thermal desorption. In addition, the key points when adopting this method for Hg-contaminated soil remediation, are summarized according to the existing scientific studies and engineering cases. Finally, the direction for future development of the technique is also pointed out. |
