摘　　要：针对多组分煤矿酸性废水(AMD)污染程度严重、治理费用高的特点,选取麦饭石、铁屑作为AMD井下原位处理的试验材料,开展了动态土柱试验研究。试验结果表明,由麦饭石及铁屑复合组成的1#柱对AMD的去除效果明显好于仅由麦饭石组成的2#柱,其对Fe2+、Mn2+、SO42-、COD的平均去除率分别为99.9%、64.5%、60.0%、53.8%,出水p H为8.0。该方法为AMD的井下原位廉价处理及麦饭石的新应用提供了参考。Aimed at the acidic mine drainage（AMD） characteristics,such as serious contamination and expensive treatment cost,a dynamic pillar study has been executed by using maifan stone and scrape iron as materials for the in-situ treatment of AMD under the shaft. The experiments show that Column 1 which consists of maifan stone and scrap iron has obviously better removing capacity than Column 2 which consists of maifan stone alone. In Column 1,the average removing rates of Fe^2＋,Mn^2＋,SO4^2-,COD are 99.9%,64.5%,60.0%,53.8%,respectively,and the effluent p H is 8.0. This method provides references for the treatment of AMD in-situ at a low cost,and new applications of maifan stone.
