ある。The process for treating activated sludge, which is excessively attached to body particles, is complicated and requires a separate dedicated device, and the sludge has poor liquefaction efficiency. The present invention relates to a fluidized bed catalytic oxidation method, and is characterized in that microbial membrane adhesion (1) uses woody polymer granules that become insoluble hydrated polymer phase particles in water. 1. In other words, activated sludge firmly adheres to the hydrated polymer phase particles as a single body, and this allows direct aeration to the lower part of the moving bed, and the tank structure is in the cylinder. The activated sludge sticks can be easily fluidized, and the excess activated sludge can be properly peeled off at all times, and it can be sedimented and removed or flowed out of the fluidized bed together with the treated water, making it possible to remove excess activated sludge. It has the advantage that no mechanism is required.

The particle size may be 5 mm to 7 mm in the mouth, which is required for the exfoliated sludge to pass through, and is larger than the mesh mouth body, that is, about 8 mm to 20 mm.
