This paper is about the migration of the total petroleum hydrocarbon (TPH) contamination, which concludes the migration rule of the TPH contamination through designing indoor soil column leaching experiment. Through researching the migration concentration of different components of TPH, experiment concludes that different components have different relative transfer abilities in typical soil, and the transfer ability has an inverse relation to the molecular weight and the ring numbers of aromatic hydrocarbon. The purpose of this research is to provide guidance to nonproliferation and remediation of the petroleum contamination.

Petroleum contamination has become one of the major soil contaminations. Aiming at petroleum hydrocarbon contamination, the multi-group opposite experiments is set; this paper use some petroleum hydrocarbon-decomposing bacteria to remedy the soil contaminated by different carbon chain petroleum hydrocarbons. Compare and study the remedial results, and study the growth of the bacteria in the decomposing process. The Study shows that the degradation rate of the bacteria to short-chain petroleum hydrocarbons is relatively high; Within 40 days without nutrient substance, degradation rate of bacteria to gasoline and diesel is 80%, degradation rate of bacteria to aromatics and lubricants is 50%, the trend of bacteria’s growth curve and the degradation rate curve of each component are approximate.
