The biological filler has the characteristics of large effective surface area and suitability for microorganism adsorption growth. The structure of the filler is characterized by having a protected internal surface area available for microbial growth. When aeration and oxygenation are carried out, the rising buoyancy of the air bubbles pushes the filler and the surrounding water body to flow, and when the air flow passes through the gaps between the water flow and the filler, the air flow is blocked by the filler and is divided into small bubbles. In such a process, the filler is thoroughly stirred and mixed with the water stream, while the air stream is thoroughly divided into fine bubbles, increasing the contact of the biofilm with oxygen and the oxygen transfer efficiency. Under anaerobic condition, the water flow and the filler flow fully under the action of the submersible mixer, so as to achieve the aim of fully contacting the biological membrane with the treated pollutant for biological decomposition.
