基于GMS的固废垃圾填埋场地下水环境影响评价

Groundwater Environmental Impact Assessment of Solid Waste Landfill Based on GMS

摘要: 本文以某垃圾填埋区固体填埋项目为研究对象，在完成野外水文地质调查和勘察的基础上，建立了研究区的地下水数值模型，利用数值模拟软件GMS对垃圾填埋区的特征离子化学需氧量进行了模拟和预测。结果显示，填埋区在污染物持续泄露情况下会随着地下水流的运动呈现逐渐增大的的趋势，污染下游地下水。因此，基于数值模拟软件的预测结果，会对项目区地下水环境预测和防治保护提供技术支撑。

Abstract: This paper takes a solid accumulation project in a landfill area as the research object. On the basis of completing the field hydrogeological survey and survey, a numerical model of groundwater in the study area is established. The numerical simulation software GMS is used to analyze the characteristic ion chemical requirements of the landfill area. Oxygen levels were simulated and predicted. The results show that the landfill area will gradually increase with the movement of ground-water flow under the condition of continuous leakage of pollutants, polluting the downstream groundwater. Therefore, the prediction results based on the numerical simulation software will provide technical support for the prediction, prevention and protection of groundwater environment in the project area.
