Abstract: This paper discusses the migration of the total petroleum hydrocarbon (TPH) contamination, which concludes the migration rule of the TPH contamination through designing indoor soil column leaching experiments. Through researching the migration concentration of TPH in different leaching amount, results shows that the ability of migration of TPH is more powerful when there is more leaching amount. But overall, the affection caused by different leaching amount is not obvious. The results of this research can provide guidance to the nonproliferation and remediation of petroleum contamination.

Abstract: 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.

Abstract: 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.

Abstract: Petroleum contamination in soil has become one of the important contamination issues. Aiming at large areas petroleum contamination in soil, this paper introduce risk assessment and contamination quantitative calculation method. Based on risk assessment model and related quantitative calculation method, select a specific petroleum contaminated site, conduct risk assessment for it and then calculated the volume of contaminated soils. As a research case, the study can provide guidance to the preliminary investigation and a basis for effective remediation.
