Integrated sewage treatment equipmentThe principle of the effectiveness of anaerobic biofilters:
1. Filtration effect: The packing material intercepts and filters large particles and suspended solids in the incoming water

2. Hydrolysis effect: Anaerobic microorganisms can hydrolyze insoluble substances of large molecules into soluble substances of small molecules
3. Absorption effect: Anaerobic microorganisms adsorb and absorb organic pollutants in water, partially for their own growth and reproduction, and partially in the form of biogas that is sealed in a U-shaped water seal

4. Denitrification effect: Denitrifying bacteria that reflux the effluent from the touch oxidation bed to the anaerobic microorganisms in the anaerobic filter can use the nitrate nitrogen in the reflux water and convert it into nitrogen to remove nitrogen substances from the wastewater. After anaerobic filtration treatment, the concentration of suspended solids, organic pollutants, and nitrogen in rural sewage is reduced, and the subsequent load on the touch oxidation bed is also reduced.
