摘　　要：为进一步掌握生物除铁、除锰滤层中铁、锰的氧化还原关系,以天然高铁高锰地下水为原水、成熟生物除锰滤料为试验材料,进行了一系列静态和动态试验。结果表明:高浓度的Fe2+能够还原高价态锰氧化物而溶出Mn2+,同时破坏滤层上部的生物除锰滤层结构,迫使高效生物除锰段下移,这一现象与微生物的存在与否无关,属于物理化学反应。In order to further investigate the redox relationship between Fe and Mn in biological filter layer for iron and manganese removal, a series of static and dynamic experiments were done, with mature media from the biological filter for manganese removal and natural groundwater containing high concentrations of Fe （ ]I ） and Mn （ 1] ）. The results show that the high valence manganese formed by bio- logical oxidation can be reduced to Mn（ I1 ） by Fe（ lI ） in the high concentration. As a result, the struc- ture of the biological layer for manganese removal is destroyed, and the efficient manganese removal can only take place in the lower-middle part of the filter. It is a physicochemical reaction, no correlation with the presence or absence of microorganisms.
