%X A treatment engineering of prepared bed was set up for the bioremediation of oil contaminated soil with oil in this study, soils contaminated with different type of oils were treated using composting process in the prepared bed and the treatment period was divided into 2 phases with total time of 210 days. When the concentration of total petroleum hydrocarbons (TPH), which consist of thin oil, high condensation oil, special viscous oil, and viscous oil, were in the range of 25.8-77.2 g.kg-1 dry soil, petroleum removal rates can reach 38.37%-56.74% by 53 days operation. In the second phase, total petroleum removal rates reached 66.59%-80.96% by the 156 days operation in the next year. The results showed that most hydrocarbon pollutants that are easier to be degraded were removed in the first phase, the remedying efficiency obviously dropped in the second phase.
