【 摘 要 】

Based on study of the hydrogeological condition and the characteristics of petroleum hydrocarbons pollution in karst groundwater, an oil refinery located in western part of a certain city is chosen as the study site to have an analysis on the control factors of groundwater petroleum hydrocarbons contamination. The study result shows that the control factors of groundwater petroleum hydrocarbons contamination are hydrogeological condition and biodegradation. The soil layer of Quaternary is very thin, the limestone is exposed in the surface, which makes the petroleum hydrocarbons easy to permeate into the water bearing layer. Karst-fractured zone in aquifer determines the migration way of petroleum hydrocarbons to be convection, but the magmatic rock in northern part has certain blocking effect on the migration of petroleum hydrocarbons. Biodegradation makes both the contamination plume area of petroleum hydrocarbons and the content of petroleum hydrocarbons decreased.
