유류오염된 연안 토양의 유분제거를 위한

Abstract

A lot of waste oil or oil mixtures like fuel oil and lubricant oil can be leaked to coastal water and soil due to destruction of vessel, industrial work and military operation. The soil in the accident was seriously polluted by waste oil or oil mixtures. It is urgently necessary to research on cleaning up and restoring from the polluted soil by environment-friendly and economical methods. Physical and chemical washing method which was adopted in this thesis can also prevent and decrease subsequent pollution. In this research, experiment was conducted for the choice of a proper surfactant. Data were collected for the surfactant and analyzed to verify the Alkyl Polyglucoside(APG)'s effectiveness. In this experiment, when APG was used as the surfactant, substantial reduction of Total Petroleum Hydrocarbon(TPH) was observed. TPH test was conducted by changing time period, APG density, and types of soil. 99% of polluted oil was removed by 1st washing. It is expected that if the polluted soil was washed with fresh water once again, the better result would be observed.
