基于HYDRUS-1D模型研究石油烃污染物在土壤中的运移规律

Study on the Migration Rule of Petroleum Hydrocarbon Pollutants in Soil of Petrochemical Enterprises Based on HYDROS-1D Model

石化企业运行过程中发生物料泄漏,不仅会对地下水环境造成影响,也会对土壤环境造成一定影响。文章针对石化企业可能发生的罐区物料泄漏的情景,应用HYDRUS-1D软件构建土壤非饱和带水流模型及溶质运移模型,对石油烃污染物在土壤环境中的运移深度、运移时间及浓度变化进行模拟预测,进一步提出保护土壤环境的相关措施,为石化企业保护土壤环境提供技术支持。

During the operation of petrochemical enterprises, the leakage of biomass will not only affect the groundwater environment,but also the soil environment.In view of the possible leakage in the tank farm of petrochemical enterprises, HYDRUS-1D model is applied to build the water flow model and solute transport model in the unsaturated zone of soil, simulate and predict the transport depth, transport time and concentration change of petroleum hydrocarbon pollutants in the soil, and further put forward relevant measures to protect the soil environment, so as to provide technical support for petrochemical enterprises to protect the soil environment.
