Abstract

In this study, electrokinetic remediation tests were performed with spiked fine-grained soil by phenanthrene which is representative hydrophobic organic contaminant of petroleum hydrocarbon. And also, the enhanced method was used with surfactant concentration variation and elapsed time to achieve more higher removal efficiency than conventional electrokinetic treatment. In conventional electrokinetic treatment, most phenanthrene was not transported. But, in the enhanced method used by the surfactant, phenanthrene moved form anode to cathode region and accumulated in cathode region. Also, the transportation rate of phenanthrene was increased with surfactant concentration increasement and elapsed time.

본 연구는 유류 화합물 중 대표적인 소수성 유기 오염물인 phenanthrene으로 오염된 세립질 지반을 실내에서 인위적으로 조성하여 Electrokinetic 정화 처리를 실시하였고, 또한 향상기법으로 계면활성제를 적용하여 정화효율과 거동을 분석하였다. 비향상된 EK 정화 처리에서는 phenanthrene의 이동은 거의 발생하지 않았고, 계면활성제를 이용한 향상기법에서는 양극(+) 근처의 phenanthrene이 음극(-)쪽으로 이동하여 누적되었다. 또한, 계면활성제의 농도가 높을수록 이동 현상이 크게 나타났으며, 시간을 증가할수록 누적된 phenenthrene이 음극(-)저수조로 전기삼투 흐름에 의해 제거되는 것을 알 수 있었다.
