摘　　要：研究铁粉的除砷效果,考察铁粉与石英砂的质量比对除砷效果的影响。结果表明,采用m(铁粉)∶m(石英砂)=2.0∶100的填料能有效去除高砷地下水中的砷,出水总砷质量浓度<50μg/L。该方法高效、经济,具有良好的应用前景。The removing efficiency of arsenic from high arsenic groundwater by using mixed iron powder and quartz sand has been studied. The effect of mass ratio of iron powder and quartz sand on the removal efficiency of arsenic has been investigated. It shows that arsenic in groundwater containing high arsenic can be removed efficiently, when the filling ratio of m （iron powder）：m（quartz sands）=2.0：100. The mass concentration of arsenic in the effluent water can be lower than 50 μg/L. The method is economic, highly efficient and highly promising.
