摘　　要：利用高铁酸钾氧化性能,研究了影响高铁酸钾对矿井废水中COD氧化去除效果的因素。结果表明,在pH=7～10时,其氧化性发挥较好;20℃～50℃时,温度对高铁酸钾氧化性基本上没有影响。水中硬度、SO42-和低含量的钠对高铁酸钾的氧化性基本没有影响,但当钠的质量浓度30mg·L-1时,能够轻微增加有机物的去除效率。Potassium ferrate （K2FeO4） was used to treat COD in mine water, and the influence factors of the potassium ferrate oxidizability were studied. The results showed that the oxidizability of potassium ferrate was rather difficult to bring into full utilization in acidic conditions, but play better when pH was 7-10. The hardness, SO4^2- and low concentration sodium had no effect on the oxidizability of potassium ferrate, but high concentration sodium （30 mg·L^-1） was able to slightly increase the removal efficiency to organic matter.
