Abstract
Thermal treatment is one of the effective methods to rapidly treat the oil-contaminated soil. However this method costs much due to the high energy consumption comparing with other conventional treatments. Microwave is recently regarded as an energy source to enhance the energy efficiency for the thermal treatment of the oil-contaminated soil. In this study, the feasibility of microwave thermal desorption technology was investigated to treat the polluted lubricating oil-contaminated soil. Microwave thermal desorption technology has been recently developed in Korea as a technically-effective as well as cost-effective technology for the remediation of lubricating oil-polluted soil. This technology uses microwave and microwave absorber as an energy source to enhance the energy efficiency for the thermal treatment of the lubricating oil-contaminated soil. Based on a series of field test results from this study, it was found that microwave thermal desorption technology can substantially reduce the remediation cost of oil-contaminated soil with low electric power consumption and contribute to low CO2 emission.
