正常工况下石油类污染物运移及对地下水的污染分析

Study on oil contaminants transfer and pollution of groundwater under normal working conditions

以兰州市某原油储备库为例,建立符合实际情况的三维地下水流数值模型,应用危害最大化原则模拟该油库营运后未来50 a内地下水中污染物迁移情况。结果表明:在正常工况下,油类污染物质量浓度为0.3 mg/L的等值线临近黄河最快需40 a;建立原油储备库不会对三滩水源地、黄河水质带来影响。

Using a crude oil reserve depot in Lanzhou as an example, a three-dimensional numerical model of groundwater was developed. The pattern of pollutant transportation in the groundwater after 50 years of operation of the crude oil reserve depot was simulated based on the maximized-hazard principle. The results show that the 0.3 mg/L isoline of oil contaminants will take 40 years to move from the crude oil reserve depot to the Yellow River, and the Santan water source and Yellow River will not be polluted under normal working conditions.
