Description

Technical Field

[0001] The utility model relates to the technical field of anaerobic biological waste gas treatment, in particular to an anaerobic biological treatment device. Background Art

[0002] The interior of the anaerobic biofilter is filled with solid fillers such as slag, porcelain rings, and plastics. Some anaerobic microorganisms adhere to and grow on the fillers, forming anaerobic biofilms, while the rest remain suspended in the gaps between the fillers. During the flow of organic sewage, it comes into contact with the fillers where anaerobic bacteria grow, which can achieve a longer sludge age under conditions of shorter hydraulic retention time. A large amount of waste gas is usually generated during the chemical manufacturing process. Usually, the waste gas contains many impurities and toxic substances. These impurities and toxic substances cannot be filtered well and are directly discharged into the air, causing air pollution. Therefore, anaerobic biofilters are needed to filter and purify them to avoid pollution caused by waste gas.

However, the existing treatment device has a relatively simple method for treating the exhaust gas, resulting in low working efficiency of the treatment equipment.
