摘　　要：针对生物滤层同步去除地下水中铁锰离子过程中'漏锰'现象进行了研究,明确了'漏锰'是由亚铁离子对锰化物氧化还原引起的,试验证明了影响反应的主要因素为MnOx质量、原水中Fe2+浓度及pH值等.Mn2+溶出的浓度与MnOx及Fe2+浓度均呈二次曲线关系,pH值小于5.0时促进反应发生,大于7.5时则抑制锰的析出.Leakage of manganese usually occurs in bio-fihers for simultaneous removal of iron and manganese from groundwater is conducted in this paper. The paper argues that reduction of MnOx by Fe^2＋ causes the phenomenon of leakage of manganese. The reaction is affected mainly by mass of MnOx, concentration of Fe^2＋ and pH value, and which is promoted while pH value below 5.0 and inhibited while pH value is over 7.5. Released manganese concentrations showed quadratic curve relationship with mass of MnOx and also Fe^2＋ concentration.
