[0022] Degradation of organic matter: The filter material in the biofilter module provides a large amount of surface area and attachment sites, providing conditions for the attachment and growth of microorganisms; through the attachment and metabolism of the biofilm, the biofilter module can effectively degrade the organic matter in the sewage and convert it into harmless inorganic substances;

[0023] Biofilm formation: In the biofilter module, a biofilm is formed on the surface of the filter material, which is a thin film of organic matter where microorganisms gather. The biofilm has a high degree of adhesion and biodegradability, which is conducive to the growth and metabolism of microorganisms and increases the biological effective area of ​​the system.

When stacking is required, the base 3 on a group of frames 1 is placed on the top of the frame 1, and the frame 1 is stuck in the inside of the splicing interface 12 during the placement process to complete the stacking work. After multiple groups of frames 1 are stacked, the steel bars are inserted into the inside of the multiple groups of steel bar insertion holes 9, and then the multiple groups of frames 1 are connected together to ensure the stability of the connection.
