广西平果铝赤泥堆场在生产氧化铝时会产生碱性比较高的赤泥淋滤液,同时也会产生硫酸盐、氟化物、铝等污染物。赤泥淋虑液下渗到地下水污染比较敏感的岩溶区会对地下水岩溶含水层造成污染。运用GMS软件模拟赤泥淋滤液在岩溶含水系统的运移情况,找出污染物的运移规律、来预测赤泥堆场的建设对地下含水层的污染,确定污染物的范围和浓度的分布。模拟结果表明：堆场离南部的岩溶管道有一定的距离,下渗的赤泥淋滤液不能很快的流入岩溶管道中,污染物主要是在裂隙和孔隙的岩体介质中运移,主要以分子扩散的形式运动,运动的速度十分缓慢。污染晕大致呈圆形向四周扩散,30 a后扩散带向东北向扩散的最远距离才...

Red mud stack field in Pingguo contry Guangxi will produce alkaline higher red mud filtrate in the production of alumina, at the same time can produce sulphate, fluoride, aluminum and other pollutants.Red mud filtrate can cause pollution of groundwater in the karst aquifer when infiltrates into groundwarter to pollute more sensitive karst area.GMS software was used to simulate migration of red mud leachate in karst aquifer system, from which found out contamination' s regular pattern and determined contamination' s ditribution and concentration.The simulation results showed that there was cert...
