Integrated biological deodorization deviceChemical reaction formula for microbial decomposition of odorous components
a. Hydrogen sulfide
H2S+202 →H2SO4
b. Methyl mercaptan
2CH3SH+7O2→2H2SO4+2CO2+2H2O
c. Methyl sulfide
（CH3）2S+5O2 → H2SO4+2CO2+2H2O
d. Dimethyl disulfide
2（CH3）2S2+13O2 →4 H2SO4+4CO2+2H2O
e. Ammonia
NH3+2O2 → HNO3+H2O
f. Amine
2(CH3)3N+13O2→2HNO3+6CO2+8H2O
As shown in the above reaction, the odorous components will decompose into substances such as carbon dioxide, water, and sulfuric acid. Spraying water can flush out these metabolites and maintain an environment suitable for microbial growth and metabolism.

Integrated biological deodorization deviceAfter being collected through pipelines, the odorous gas enters the biological filtration deodorization device. The airflow and circulating liquid complete three processes of biological gas-liquid diffusion, liquid-solid diffusion, and biological oxidation during the process of passing through the biological packing layer. The microorganisms in the biofilm on the surface of the biological packing take the odorous gas substances as nutrients, and the odorous substances and VOCs are oxidized and decomposed by the microorganisms, generating energy during the transformation process to provide energy for the growth and reproduction of microorganisms. The transformation of odorous gas substances continues, and the purified gas is discharged from the induced draft fan.

Parameters of biological deodorization device:

Note:

If the water source needs to be filtered, a filtering device should be equipped, and the head of the water pump should consider the pressure loss of the filtering device.

2. The determination of fan pressure requires detailed calculation of duct losses.
