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pH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。
針對多組分煤礦痠性廢水（AMD）汙染程度嚴重、治理費用高的特點，選取麥飯石、鐵屑作為AMD井下原位處理的試驗材料，開展瞭動態土柱試驗研究。試驗結果錶明，由麥飯石及鐵屑複閤組成的1#柱對AMD的去除效果明顯好于僅由麥飯石組成的2#柱，其對 Fe2+、Mn2+、SO42-、COD 的平均去除率分彆為99．9%、64．5%、60．0%、53．8%，齣水pH為8．0。該方法為AMD的井下原位廉價處理及麥飯石的新應用提供瞭參攷。

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 Fe2+,Mn2+,SO42-,COD are 99.9%,64.5%,60.0%,53.8%,respectively,and the effluent pH is 8.0. This method provides references for the treatment of AMD in-situ at a low cost,and new applications of maifan stone.
