摘要
依据渣库现状和污水水质特点、污染途径、水文地质条件,采用GMS地下水数值模拟系统分别对场地的地下水流场和溶质运移情况进行了数值模拟,模拟出污染迁移途径。根据模拟运移结果及水位地质勘察成果,采用防污染立体复合防渗屏障系统,实现污染源与底部及周边土壤、地下水、地表水的多重严密隔离,能够最大程度管控污染源泄漏污染地下水及土壤。
According to the present situation of the slag depot,the characteristics of sewage quality,pollution routes and hydrogeological conditions,the groundwater flow field and solute transport in the site were numerically simulated by GMS groundwater numerical simulation system,and the pollution migration routes were simulated.According to the results of simulated migration and geological survey of water level,the pollution-proof three-dimensional composite seepage-proof specific pathogen free is adopted to realize multiple tight isolation of pollution sources from the bottom and surrounding soil,groundwater and surface water,which can control the leakage of pollution sources to pollute groundwater and soil to the greatest extent.
