摘　　要：生物除锰滤柱培养成熟后,通过改变试验用水pH值、进水浓度、亚铁离子等影响因素,得出以下结论(1)在铁锰细菌适宜的pH范围内,其对锰的氧化效率也随着pH的升高而提高。(2)在本实验条件下,进水锰浓度最高可以提高到3mg/L。(3)Fe2+对生物过滤除锰有明显的影响,在进水中不含Fe2+的情况下,生物滤柱出水锰很快就会超标。The experiments were done by changing the influencing factors such as pH value, influent concentration, ferrous ions, and others after the biological manganese removal filter has been brought up. Conclusions are drawn as follows： （ 1 ）In the appropriate range of pH, the oxidation efficiency of bacteria on manganese raises with the increasing of pH. （2） In the experimental conditions, the highest manganese concentration of the influent can reach to 3mg/L. （3） There is significant impact of Fe^2＋ on biological manganese removal filter and the manganese concentration of the effluent would soon be over standard if without Fe^2＋.
