摘要
Abstract
[Objective] The groundwater pollution status of a depot in Huangling County of Shaanxi Province were simulated to provide scientific guidance for auxiliary prediction and prevention of groundwater pollution in oil depot area.[Methods] Based on the initial parameters obtained through field investigation,we established a groundwater flow model using Visual Modflow software.Then through model identification and verification,we obtained the final hydrogeological parameters.And we derived a groundwater solute transport model in reference to water flow equation and contaminant transport equation.[Results] We simulated two hypothetical scenarios:one is under normal working condition and another one is when oil leakage happened for the oil tank.The range and degree of pollution were predicted by numerical simulation.The impact of pollutants was predicted that it would become the greatest in the following 20th year of leakage.[Conclusion] The results obviously showed that the contaminant transport mainly via flow direction,the impact on water environment tends to gradually increase with time going on.And there was a negative correlation between the concentration of pollution and the distance from oil tank.Oil tank leakage will cause more severe pollution to the water environment than normal operation can do,under that case,pollution is far beyond the scope of the depot area.关键词
