生物滤层中Fe^(2+)的作用及对除锰的影响

The Function of Fe^(2+) and Its Effect on Manganese Removal in Biofilter Bed

通过无菌滤层与生物滤层的除铁、除锰对照试验 ,得出了生物滤层不但可以同时去除原水中的铁与锰离子 ,而且Fe2 + 参与了除锰菌的代谢 ,对维系生物滤层中生物群系的平衡起到了至关重要的作用。同时 ,生物滤层对Fe3+

Based on the comparative test for the removal of iron and manganese in aseptic filter bed and biofilter bed, a conclusion was drawn that simultaneous removal of iron and manganese ion from raw water is achieved in biofilter bed, while Fe 2+ participates in the metabolism of manganese removal bacteria. It has important effect on the balance of biologic community in biofilter bed. Furthermore, the biofilter bed serves as a good function of trapping the Fe 3+ solid micro-particles.
