| Outline of Final Research Achievements |
The contamination of the ground has become a social problem. There is no established technology for recovering machine oil with high adhesion and viscosity to soil and poor volatility from inside the ground by non-excavation. In this study, some experiments to record the progress of purification by surfactant in simulated oil contaminated ground using the laboratory soil tanks were conducted under various conditions. The relationship between the conditions such as the surfactant injection pattern, the method of injection / suction, the scale of the laboratory soil tanks, and the progress of purification was considered. As a result, a point of control of flow field with high purification efficiency was found.
