Abstract： |
The present invention relates to a method for treating polychlorobiphenyls (PCBs) in polluted soil. It is characterized by that it uses wirowave as heat source to heat the soil polluted by PCBs in container, utilizes the lots of aqueous vapour produced by action of microwave and water in soil to carry off the PCBs molecules from soil, namely microwave thermal desorption process, to implement separation of PCBs and soil, then the volatilized pollutant can be trapped, and treated by alkali-catalyzed decomposition process. |
