The purpose of this study was to develop the soil washing recycling system by Dissolved Air Flotation(DAF) process. DAF Process was applied to contribute to environmental protection from soil restoration work that is friendly remediation of a soil washing process. The contamination removal efficiency was established from the pilot plant of waste soil washing recycling system on S company's oil storage property site in P city. It Measured treatment efficiency of whole soil washing recycling system with CODMn, SS, T-N, n-H(mineral oil), pH. The optimal operating condition of the soil washing recycling system using the Dissolved Air Flotation(DAF) process are hydraculic retention time(HRT) 10min, return ratio(RR) 50%, skimming ratio(SR) 5%.
