Abstract

The invention relates to a membrane bio-aeration filter, which comprises a bio-aeration filter body, the bio-aeration filter body comprises a filter body, a water distribution plate, a gas distribution pipe and a filler, the top of the filter body is open, the water distribution plate is installed in the middle of the filter body, the water distribution plate and the bottom of the filter body define an anaerobic zone, the anaerobic zone is communicated with the outside through a water inlet pipe and a blow-down pipe respectively, the upper part of the water distribution plate is filled with the filler, a gas distribution pipe is mounted on the water distribution plate, a support frame, a membrane component, a self-priming pump and a water production tank are provided, the support frame is mounted above the water distribution plate, the filler is positioned below the support frame, the membrane component is fixedly mounted on the support frame, and a liquid outlet of the membrane component is communicated with the water production tank through the self-priming pump. According to the invention, the membrane component is combined with the biological aeration filter, so that the concentration and mud-water separation efficiency of the biological aeration filter tank are improved, the sewage treatment efficiency is integrally improved, and the biological aeration filter has a good application prospect.

Description

technical field [0001] The invention relates to the technical field of sewage treatment equipment, in particular to a membrane biological aeration filter. Background technique [0002] Biological aerated filter is a structure for sewage treatment, referred to as BAF. The tank is filled with granular filter material as a carrier to form a fixed bed, and the microbial group is attached to the surface of the carrier to form a biofilm. The middle and lower part of the filter material layer is aerated to supply oxygen. The filter layer relies on the biofilm attached to the surface of the carrier to adsorb, oxidize and decompose the pollutants, which can purify the sewage. The granular material layer also has a certain flow interception and filtration effect, but the interception effect is not very good. And as the water flows, the biofilm attached to the surface of the filter material will also be lost. [0003] Therefore, in order to separate the muddy water in the filtered se...
