摘　　要：以KMnO4改性锰砂、未经改性锰砂、陶粒和碳酸盐岩4种载体材料,分为接种Mn(Ⅱ)氧化细菌试验组和未接种试验组,在好氧条件下探究不同Mn2+浓度、HRT、重金属离子以及pH值对接种Mn(Ⅱ)氧化细菌在不同填料上去除Mn2+效果的影响。试验结果表明,在进水Mn2+浓度为20 mg/L时各组去除效果最佳;重金属存在对各组影响不明显;在Fe2+存在的条件下,接种改性锰砂和非改性锰砂组处理效果优于非接种组;低pH值对Mn(Ⅱ)氧化细菌影响显著。Effects of different initial Mn2＋ concentrations, hydraulic retention times （HRTs）, initial heavy metal ions concen- trations and pH on treatment of manganese in acid mine drainage by manganese-oxidizing bacteria inoculated on 4 different base materials as modified manganese sand, unmodified manganese sand, ceramsite and carbonatite, static test under aerobic conditions were studied. Experiment results showed that in the condition of initial Mn2＋ concentration 20 mg/L, Mn2＋ removal efficiency of each group was stabilized and was found to be the best. The existence of heavy metal ions did not affect the Mn2＋ removal efficiency of each group effectively. In the existence of Fe2＋, Mn2＋ removal efficiencies of inoculated groups were better than uninoculated groups. Low pH affected manganese-oxidizing bacteria obviously.
