Abstract
The heating characteristics of water and sand were investigated to understand the basic features of a microwave soil pollution treatment system and the reasonableness of this method was examined. The evaporation and temperature change of water by microwave irradiation were dependent on its volume and sand showed a three-fold temperature change compared with water. When microwave energy was applied, water showed an even variation in temperature on the whole, however, there was approximately 30□ difference according to the location inside the sand. Sand temperature was observed to show a larger difference as it was horizontally and vertically closer to the microwave irradiation point and horizontal temperature variations were more evenly distributed than vertical variations. Heating characteristics according to the particle size of sand showed that the temperature change was larger when the particle size became smaller and the moisture content of sand was found to influence its heating behavior. In the conditions of experiment, about 50% of the benzene in sand was volatized after 23 minutes of heating and 85% of the total benzene was removed from the sand after 60 minutes of microwave irradiation. For real soil test, more than 70% of BTEX was successfully removed from the soil after 120 minutes of heating. Copyright © Taylor & Francis Group, LLC.
