Article Preview

A full-field investigation was conducted of thermal desorption remediation of soil polluted by 1, 2-dichloroethane (1, 2-DCA). The effects of soil type, system temperature, thermal desorption time, and stirring speed on the residual concentration of 1, 2-DCA were determined. The residual concentration of 1, 2-DCA decreased with increasing viscosity, system temperature, thermal desorption time, and stirring speed. Optimal thermal desorption conditions for moderately polluted clay soil were a system temperature of 130°C and thermal desorption time of 50 min with stirring. Optimal thermal desorption conditions for heavily polluted clay soil were a system temperature of 130°C and thermal desorption time of 90 min with stirring. This study provides technological parameters and theoretical guidance for engineering.
