【 摘 要 】

Solid waste landfill will produce leachate during its landfill phase and after the closure. The pollutants will pollute the regional groundwater. A three-dimensional coupled numerical model of groundwater flow and solute transport was established based on Modflow by researching a solid landfill project to simulate the migration process and range of Cr6+ in leachate when both horizontal and vertical anti-seepage layers are damaged. The results show that the migration range of Cr6+ is small and the pollution on groundwater is weak. Therefore, the feasibility of landfill disposal of solid waste in this area is proposed, which provides a theoretical basis for landfill disposal.
