Apparatus of multi-staged fluidized biofilter

摘要

According to the present invention, the compartments in which the perforated holes separating the stages of the fluidized bed biofilters are arranged are not directly bonded to the inner wall of the fluidized bed biofilter by welding or the like for each height of the stages perpendicular to the height direction of the fluidized bed biofilter. There are no problems such as difficulty of work due to space occlusion, and a window connected to the outside of the inner wall of each stage of the fluidized biofilter to fill the fluidized microbial carrier from the outside of the fluidized biofilter to each stage of the fluidized biofilter. The multistage fluidized bed biofilter does not require additional installation.
