    • A method and device for treating manganese containing water, wherein meltable manganese in water is removed by crystallizing by passing untreated water containing carbonic acid ions in an upstream direction to a fluidized-bed reaction column having no support bed and using manganese sand as a fluidizing medium and by regulating a pH value of treated water inside the fluidized bed. Meltable manganese in untreated water, as well as suspended manganese, being removed by removing a suspended material layer in untreated water that has passed the fluidized bed at the upper portion of the manganese sand fluidized bed of the fluidized-bed reaction column and a required amount of treated water being introduced into untreated water for cyclic use.
    • 一种处理方法和装置,用于通过将待处理的水作为向上的流通过不具有载体床的流化床反应塔,通过在待处理的水中结晶并除去待处理的水中的可溶性锰来处理含锰水; 并且通过调节所述流化床中待处理的水的pH值来测量。 通过除去所述悬浮固体层,还将悬浮的锰与所述可溶性锰一起除去待处理的水中,通过在所述锰砂流化床中形成待处理的水中的悬浮固体成一层。 此外,将所需量的处理水引入待处理的水循环使用。
