Abstract
This study was performed to evaluate effect of extraction mode on SVE efficiency for fuel-contaminated soil. A gas station was selected for this study. As a result of pressure test in well head, soil texture of contaminated site under the gas station was very different from site to site. SVE system was operated in intermittent mode (1hr extraction / 3hr rest) or continuous mode. Capacity of air blower was
본 연구에서는 유류로 오염된 현장 주유소를 대상으로 토양증기추출 공정 적용시 연속추출과 간헐추출 운전의 효율성을 검토하였다. 공기주입 후 압력을 측정한 결과 동일 조건에서도 공기주입정 헤드(head) 압력이 상이하게 나타나 실험부지내 토양이 매우 불균일하다는 것을 알 수 있었다. 간헐식은 1시간 가동 후 3시간 정지시켰으며, 연속식은 50분 가동 후 10분 휴지하는 것을 연속추출한 것으로 가정하였다. 송풍기의 용량은
