Abstract
This study was conducted to observe the removal efficiency of oil-contaminated soil by various tests using microwaves and high-temperature heating elements. The water content was measured with the treatment amount, which was lowered to 300g in a relatively short amount of time. The treatment rate of TPH(Total Petroleum Hydrocarbons) showed the highest value with 70.1% when the SiC-activated carbon heating element was at 4 kW/kg, compared to the SiC heating element used alone. In particular, the higher electric power became, the higher treatment rate became, except at 3 kW. In the case of the heating element made by the fusion of SiC and activated carbon, the internal temperature exceeded $300^{\circ}C$ and again fell when it was treated at 4 kW for about 2 minutes. Then, after about 8 minutes, it rose again. On the basis of such results, the energy content necessary for the sample was calculated according to the electric power of microwaves, and tthe constant of TPH treatment was measured by tests on the treatment characteristics of oil-contaminated soil.
