摘　　要：文章根据氧化铝工业产生赤泥的成分和性质,探索了赤泥和粉煤灰用于工业烟气脱硫的可行性。通过小型固定床反应器脱硫实验,分析了赤泥和粉煤灰的比例、样品含水量、SO2浓度等对脱硫效率的影响,为赤泥和粉煤灰在烟气脱硫领域的综合利用提供了参考。Based on the composition and properties of red mud generated by the alumina industry,the paper explored the feasibility of using red mud and coal ash for industrial flue gas desulfurization.The influences of the ratio of red mud to coal ash,the water content of sample and SO2 concentration on the desulfurization efficiency were analyzed through the desulfurization experiment in a small-sized fixed bed reactor,thus providing a reference for the comprehensive utilization of red mud and coal ash in the field of flue gas desulfurization.
