采用添加硫酸盐还原菌（SRB）与零价铁（Fe0）构建以麦饭石（MFS）为主体的可渗透性反应墙，模拟井下煤矿酸性废水（AMD）原位修复过程，比较生化强化与物化强化两种方式对处理能力的影响。结果表明，添加硫酸盐还原菌的麦饭石（SRB-MFS）和添加零价铁的麦饭石（Fe0-MFS）去除能力均强于单独MFS；SRB-MFS对SO42-的去除有明显优势，但对Mn2+的去除不及Fe0-MFS，两种强化方式对可溶性Fe2+的去除效果差别不大，出水均为弱碱性。%Sulfate reducing bacteria (SRB) and zero-valent iron (Fe0) were added to permeable reactive barriers (PRB) containing maifan stone (MFS) respectively. An experiment simulated the process of treating AMD in-situ by these PRBs was conducted to investigate the effects of different reinforcement modes:one strengthened by biochemistry and the other strengthened by physicochemistry. The results showed that both PRB-1(SRB-MFS) packed with SRB and MFS and PRB-2 (Fe0-MFS) packed with Fe0 and MFS had a batter performance than PRB-3 packed with MFS alone. The SRB-MFS had a higher SO42-removal efifciency than others, but lower Mn2+removal efifciency when compared to Fe0-MFS. However approximate Fe2+removal efifciencies were achieved by SRB-MFS and Fe0-MFS, as well as both eflfuent pH value were neutral or alkalescency.
