유류오염토양 복원을 위한 지중 오존산화기술의 현장규모 적용

Abstract

Field scale application of in-situ ozonation were carried out for remediation of variably saturated soils contaminated with diesel fuel with 3 dimensional test cell (3mx2mx2m). After 20 days of ozone injection, more than 90% of removal rate was observed through the 3-D test cell. This result might be caused by uniform distribution, relatively low oxidant demand, and low water content of soils, as well as high oxidation potential of ozone. However, less than 50 % of injected ozone was monitored through the 3-D test cell even after 20 days of injection.
