摘　　要：通过静态浸泡实验和动态淋溶实验,研究了用粉煤灰处理矿井水重金属污染的可行性,结果表明:粉煤灰处理矿井水中高浓度的重金属时效果较好;对Cu,Zn,Pb和Cr的去除效果较好,去除Cd的效果较差;粉煤灰投加量和重金属的去除率成正相关性。hrough static soaking and dynamic leaching experiments, the feasibility study was made on the application of fly ash to dispose the heavy metal pollution of mine water. Study results indicated that the effect of using fly ash to dispose heavy metal is good when the heavy mental concentration in mine water is high, its effect is better for the removal of Cu,Zn,Pb and Cr, but is worse for the removal of Cd the adding amount od fly ash is in direct proportion to the removal rate of the heavy metal.
