摘要
地下水溶质运移模型是找出污染物迁移规律、确定污染范围及污染物浓度分布的重要手段,可以为地下水资源管理和地下水污染修复提供定量依据。以北京市西郊典型地段为研究区,利用GMS软件建立地下水溶质运移模型,在南水北调来水后,地下水开采方案改变条件下,预测了Cl-、NO23-和THD浓度场。结果表明:垃圾填埋场污染物浓度整体呈上升趋势,劣质水面积增大,需要对原有地下水开采方案进行调整,防止地下水污染范围扩大。
Solute transport in groundwater model is an important way to identify the contamination transfer rule and define the scope of pollution and the concentration distribution.It can provide the quantitative basis for the groundwater resource management and groundwater pollution repair.Using GMS software to establish groundwater solute transport model for a case study on the typical district trash dump of the western suburbs of Beijing,the concontration field of Cl-,NO2-3 and THD was predicted in the conditions of underground extraction program change after south-to-north water diversion project.The results show that the landfill pollutant concentration is in the overall upward trend and poor-quality water areas are becoming larger.So it is needs to adjust the original programs and prevent groundwater pollution scope expanding.
