摘　　要：采用中和处理法研究了酸性矿山废水中锰离子的去除机制。通过对比不同加碱速率和处理工艺对锰离子去除效果的影响,结果表明,曝气搅拌处理相较于传统机械搅拌工艺去除效果更为显著,综合考虑去除效率和经济成本因素,选定最佳加碱速率为8.88 g/L。同时,本文还阐释了共存离子去除酸性矿山废水中锰离子的机理。结果表明,Al^(3+)对锰离子去除效率的促进作用作为显著,Fe^(2+)在不同处理工艺中影响机制有所差别。The neutralization method was used to study the removal mechanism of manganese ions in acid mine waste-water.According to the comparison of the effects of different alkali addition rates and treatment processes on the removal effect of manganese ions,the result of experiments showed that the removal effect of aeration and stirring treatment was more significant than that of the traditional mechanical stirring process.Considering the influence of removal efficiency and economic cost factors,the rate of 8.88 g/L was considered comprehensively to select the best.At the same time,the mechanism of coexisting ions to remove manganese ions in acid mine waste-water was also explained.The results illustrated that the promotion effect of Al^(3+)on the removal efficiency of manganese ions was significant,and the influence mechanism of Fe^(2+)was different in different treatment processes.
