用赤泥去除酸性矿井水中重金属污染物的初步研究

Preliminary Study on the Removal of Heavy Metal Contaminants in Acidic Mine Drainage using Red Mud

摘要: 利用碱性赤泥去除酸性矿井水中的污染物。通过比较不同的赤泥改性方法、赤泥改性温度、反应温度、反应时间及赤泥和矿井水不同的固液比等条件下水样中的pH值和Cu、Zn、As、Cd、Hg、Pb重金属元素的去除率，获得各污染物元素的最佳去除条件。为治理赤泥和酸性矿井水的污染开辟一条新的途径。

Abstract: A method using alkali red mud(RM) to remove the contaminant elements in acidic mine drainage(AMD) was proposed.Some factors influencing the removal efficiency of the heavy metal contaminants,such as reaction temperature and time,pH value and ratio of soli
