Problems solved by technology

The microorganisms attached to the filler tend to gradually decrease along the direction of liquid flow, which limits the further improvement of the treatment capacity of the biofilter
At the same time, the liquid flow state in the traditional biofilter and the attachment growth mode of microorganisms reduce the biological growth and biomass accumulation along the bottom of the filter bed, and the corresponding reduction in the thickness of the biofilm, which leads to a gradual decrease in the treatment capacity of the filter bed at the bottom, which inhibits The treatment capacity of the biofilter is further improved, especially for high-concentration ammonia-nitrogen influent, and the low concentration of organic matter at the bottom of the filter bed is not conducive to the occurrence of denitrification process

Abstract

A biologic dripping filter pool is composed of water inlet pipeline, water distributor, layered frame structure, guide tracks, drawer-type filler baskets, filtering material layer, and water corrector. Said layered frame structure has at least 4 guide track layers and relative drawer-type filler baskets.

Description

Biological drip tank Technical field: The invention belongs to the field of water treatment, and in particular relates to a sewage treatment device, in particular to an energy-saving, modular, layered, drawer-type biological filter. Background technique: The biological trickling filter is mainly used for sewage treatment and is a kind of biological filter. Traditional biofilters generally adopt a relatively closed columnar structure. During the ventilation process of this type of biofilter, air passes through the filter bed from bottom to top or top to bottom. After literature search, it is found that the Chinese patent number 02215898.7 is called an integrated biological filter. The patented technology reads as follows: the utility model integrated biological filter includes a biological filter, a sedimentation tank, a gap ring groove of the sedimentation tank, and a drainage tank. The mud outlet, the drain outlet, is characterized in that: there is a column on the sedim...
