토양세척공법의 현장 적용을 통한 유류오염토양정화

Soil washing was applied as a supplementary step of soil remediation at a petroleum oil contaminated site. A soil washing system was designed, assembled, and operated at the site. A field screening method with PetroFlagTM was adopted at the site to find the exact boundary of contaminated area as soil excavation progressed and to verify the concentration of treated soil. The system operation showed the cleanup efficiency of 90% at the compatible cost compared to other methods.
