摘要
在已有资料的基础上,以云南省丽江市某矿区为研究对象,通过对该研究区的水文地质条件进行了详细调查后,结合研究区监测井,利用 GMS 软件建立该区域的地下水水流场模型和溶质运移模型.在合理的误差范围内模拟计算了水流场模型,且模拟预测了主要污染物 Mn离子在地下水中的运移规律.研究结果表明,在污染物持续泄露了 28a 预测期内,Mn 离子扩散约 335 m,需合理对地下水进行监测、做好厂区的防渗工作和应急管理工作,对下游饮用的及作为农业用水、生活用水中的泉点作系统监测.场地水土环境质量评价及地下水污染治理可用本文的研究作为科学依据.
Abstract
Based on the existing data,this paper takes a mining area in Lijiang City,Yunnan Province as the research object.After a detailed investigation of the hydrogeological conditions in the study area,combined with the monitoring wells in the study area,the GMS software is used to establish the groundwater flow field model and solute transport model in the area.The flow field model is simulated and calculated within a reasonable error range,and the migration law of main pollutant Mn ion in groundwater is simulated and predicted.The research results show that during the 28-year prediction period of the continuous leakage of pollutants,the diffusion of Mn ions is about 335m,so it is necessary to reasonably monitor the groundwater,do a good job in the anti-seepage work and emergency management of the plant,and systematically monitor the spring points in the downstream drinking water and as agricultural water and domestic water.The research of this paper can be used as the scientific basis for the evaluation of soil and water environmental quality and the treatment of groundwater pollution.
