Abstract

Abstract

Microwave thermal desorption of organic contaminants from soil has gained much attention due to its high efficiency and cleanliness. In recent years, most of the microwave soil thermal desorption research devices are converted from household microwave ovens, and cannot meet the high power requirement for the practical application of microwave thermal desorption, high-precision temperature control, and other conditions. Therefore, in this paper, o-xylene in benzene was chosen as the target pollutant, the self-matched contaminated soil was used as the sample, a self-made microwave thermal desorption device was used as the platform for the experiments, and single-factor influence experiments were conducted for the process conditions such as microwave power, microwave heating duration, and soil moisture content, etc. Meanwhile, a microwave heating soil model was constructed, the same conditions were set, and the matching results were obtained. The model was also used to speculate the hypothesis of other single-factor influence experiments. The experimental and simulation results showed that the optimal power of microwave thermal desorption of soil was 1600 W, the thermal desorption time was 27 min, the water content was 17%, and it was presumed that the best removal rate of o-xylene was achieved when the sample was placed near the center of the heating chamber.
