摘要
受矿山废水排放的影响,金昌市地下水的污染物以重金属离子为主.同时金昌地区有着巨厚的包气带,其物质组成由砂砾石、亚粉土、亚粘土为主.本文在对污染组分进行取样分析的基础上,对包气带的吸附能力进行研究,结论认为其对重金属离子有着较强的吸附能力,可以有效降低地下水的污染水平.
As the impact of the discharge of the mine wastewater,heavy metal ions dominate in the groundwater contaminate in Jinchang,in which existing thick zone of aeration primarily consisting of sand gravel,silty soil and clay.This text studys the ability of adsorption on the base of sampling and analysis of the contaminant components,drawing a conclusion that the local zone of aeration has a relatively high level of adsorptive capacity by which it can bring down the level of contamination in groudwater efficiently.3figs.,1tab.,2refs.
