Abstract

Abstract

In this paper, a coupling mathematical model of the moisture reactive petroleum pollutant migration is established on the bases of field investigation and indoor and outdoor tests in Shenyang Fushun irrigation area. In this model, the numerical method is first used to simulate the distribution pattern of the soluble oil (effective oil) and to analyze quantitatively the feasibilities of different restoration projects for the oil polluted soils. The research results show that the chemical reaction in the soil may lower the migration speed of the soluble oil far less than the penetration speed of the soil water. Therefore, the soluble oil is mainly distributed in the ploughed soil layer, making it difficult to pollute directly the groundwater by the penetration of the polluted water for irrigation. In addition, the controlling plans of the irrigation by the mixed clean and polluted water and of the change in the crop structures may greatly reduce the soluble oil concentration in the soil, but the complete elimination of the oil polluted soil must depend on the reasonable irrigation by the surface water or/and groundwater.
