본 논문은 유류오염토양의 마이크로웨이브를 활용한 열탈착시스템의 적용성 평가를 목적으로 한다. 마이크로웨이브 제너레이터와 마이크로웨이브 반응발열체 및 토양컨테이너로 이루어진 열탈착시스템을 제작하여 유류오염토양 정화시험을 수행하였다. 열탈착시스템의 발열온도(350, 550℃)를 조절하면서 유류(경유)오염토양 (TPH 8,420mg/kg)의 정화특성을 분석한 결과, 발열온도 변화에 따라 정화율이 약 20% (76→98%) 증가되는 것으로 나타나 마이크로웨이브 열탈착시스템을 활용한 유류오염토양의 정화가 가능하였다.
In this paper, the applicability evaluation of using microwave thermal desorption technology was investigated to treat the oil-contaminated soil. Oil contaminated soil remediation test was performed to produce a thermal desorption system consisting of microwave generator, microwave absorber and a test container. Heating temperature(350, 550℃) was controlled by microwave thermal desorption system. then, the result of the remediation property of diesel contaminated soil(TPH 8,420mg/kg) was found to increase approximately 20% (76→98%) of removal efficiency according to the heating temperature. From the lab test, it is found that this technology has a potential to complete the remediation process of the oilcontaminated soil.
