Abstract

This research was performed to evaluate the feasibility of in situ soil flushing for TPH-contaminated soil remediation. It was conducted in batch test as fundamental research for in situ soil flushing. The 30% of initial TPH concentration was removed by shaking only in batch test. The removal efficiency of TPH in case of groundwater as surfactant dilution solution was approximate 2~6% lower than that of distilled water. Mixing ratio of soil to surfactant solution did not practically effect on the TPH removal efficiency. In the experiment of using single or mixed surfactant solution with 0.1~4.0 wt%, Tween-80, SWA-1503, SWA-1503+SDS showed averagely over 80%. It was determined that the optimum surfactant concentration was 0.1 wt% because there was no significant difference between concentrations of 0.1~4.0 wt%.

본 연구는 실제 유류오염토양을 in situ 토양세정법으로 정화시 기술 적용성을 평가하기 위한 회분식 기초연구로 적정 계면활성제의 종류와 농도를 결정하고자 하였다. 증류수만의 진탕효과로 인한 TPH 제거는 약 30%이었으며, 계면활성제 희석시 사용되는 용액으로는 증류수를 사용한 경우에 비하여 지하수(해수 혼합)의 유입으로 인하여 약 2~6%의 효율저하가 나타났다. 토양과 계면활성제 용액비는 회분식 실험에서 TPH 제거효율에 미치는 영향이 미미하였다. 단독 또는 혼합 계면활성제 농도를 0.1~4.0 wt%까지 변화시켜 세정한 결과 종류별로는 Tween-80, SWA-1503, SWA-1503+SDS에서 평균 제거율이 80% 이상으로 대체적으로 높은 효율을 보였으며, 농도에 따른 차이는 크지 않아 0.1 wt% 농도를 최적 농도로 판단하였다.
