A fluidized biofilm media formed by two or more outer mesh media, each medium having a vessel- shaped structure formed with a plurality of tubular pores or through holes of a variety of shapes in order to have a large specific surface, and for the water current and bubbles to smoothly communicate, a spacing formed by the media and filled with a microorganism contact material having a large specific surface and porosity, wherein one or more of a group comprising the first and second outer media and the microorganism contact material is formed with one or more materials out of synthetic resin substance and ceramic substance having a relatively larger specific gravity, and the other one or more is formed with synthetic resin substance having a relatively smaller specific gravity, such that a weighted average specific gravity of the assembly- completed biofilm media can be accurately adjusted to cater to the fluidity, and the outer media is disposed with a plurality of assembly holes and assembly rods, enabling to simply and fixedly couple the first and second outer media. |
