Abstract: The bioremediation of soils contaminated by different types of petroleum were carried out with composting process in a prepared bed. By the measures of nutrient and microbiological agent addition, and moisture and pHcontrol, an ideal environment for microbes was obtained. When total petroleum hydrocarbons, which consist of thin oil, high condensation oil, special viscous oil, and viscous oil, were in the range of 25.8~77.2g·kg-1 dry soil, the petroleum removal rate could reach 38.37~56.74% by 2 months operation. The contents of aromatic hydrocarbon, asphaltum and resin were important factors controlling the degradation of petroleum. 6 fungi, 6 bacteria and 1 actinomyces were found to be the dominant strains for petroleum degradation.The results could provide theoretical bases for remediation of soil contaminated by petroleum.
