[0002] The interior of the anaerobic biological filter is filled with solid fillers, such as slag, porcelain rings, plastics, etc. Some anaerobic microorganisms attach and grow on the fillers to form anaerobic biofilms, while the other part is suspended in the gaps between the fillers. During the flow, organic sewage comes into contact with the fillers where anaerobic bacteria grow, and a longer sludge age can be obtained under shorter hydraulic retention time conditions. The average sludge age can be as long as 100 days or more.
