Preferably, the process occurring in the processing space 32 is:

(1) water-soluble infiltration: the surface of the filler is covered with a water layer, and chemical substances in odor are dissolved in the surface layer after contacting the filler and are converted into a water phase from a gas phase, so that bacteria in the filler can be further absorbed and decomposed. In addition, the porosity of the filler enables the filler to have an ultra-large specific surface area, so that the gas phase and the water phase have larger contact areas, and the transmission and diffusion rate of the gas phase chemical substances in the water phase is effectively increased. Therefore, the water-soluble permeation process is actually a physical action process, and the high speed of transmission diffusion means that the filler can rapidly reduce the concentration of the odor to an extremely low level.

(2) Biological absorption: the malodorous components in the aqueous solution are adsorbed and absorbed by the microorganisms, and the malodorous components are transferred from the water to the microorganisms.

(3) Biological oxidation: a process for degrading contaminants by biological oxidation. The obligate bacteria (the processing strains obtained by screening according to the type of the odor source) in the filler take the pollutants as food, convert the pollutants into self nutrient substances, and enter the self circulation process of the microorganisms, thereby achieving the purpose of degradation.

Reaction when the microorganism decomposes the malodor component:

hydrogen sulfide: h₂S+2O₂→H₂SO₄

Methyl mercaptan: 2CH₃SH+7O₂→2H₂SO₄+2CO₂+2H₂O

And (3) methylated sulfur: (CH)₃)2S+5O₂→H₂SO₄+2CO₂+2H₂O
