Description

Anaerobic fermentation tank of categorised filler of hybrid

Technical Field

The invention relates to the technical field of fermentation, in particular to an anaerobic fermentation tank with mixed classified fillers.

Background

Anaerobic fermentation device utilizes anaerobic microorganisms to degrade organic pollutants in waste water and store partial marsh gas, raw materials enter the tank body and react with anaerobic microorganisms generated in the tank body, so that the organic pollutants in the raw materials are degraded, most of the raw materials are decayed when being sent into the anaerobic fermentation device, large odor is generated, air around a classification place is polluted, therefore, the odor generated by the raw materials needs to be treated, the mode of treating the odor by adopting a biofilter is most environment-friendly and most clean, and the biofilter filler is a biological carrier for treating the odor.
