Jet flow aeration biological film reaction tank

Abstract

The invention discloses a jet flow aeration biological film reaction tank. The jet flow aeration biological film reaction tank is characterized in that a tank body is separated into a biochemical reaction zone and a settling zone through a separating plate; a through hole is formed in the lower end of the separating plate, so that the biochemical reaction zone is communicated with the settling zone; a biological film is arranged at the upper part of the biochemical zone; a sludge discharging device is arranged at the bottom part of the biochemical reaction zone; the biochemical reaction zone is also internally provided with a submersible jet flow aeration machine and a submersible stirrer which stretch under the biological film; a water inlet pipe in which sewage can flow is arranged on the upper end of the biochemical reaction zone; a sludge-water separator is arranged in a position, which corresponds to the through hole formed in the bottom part of the separating plate, of the bottom part of the settling zone; inclined pipes are arranged at the upper part of the sludge-water separator in the settling zone; a water collection tank is arranged at the upper parts of the inclined pipes; a water outlet pipe which corresponds to the water collection tank and is communicated with the water collection tank is arranged at the outer part of the settling zone. The jet flow aeration biological film reaction tank disclosed by the invention has the beneficial effect that the key technical effect of effectively realizing microorganism immobilization on the basis that mass transfer and microbial activity are not influenced is realized; a relatively wide application prospect is obtained.

Description

technical field [0001] The invention relates to a biofilm reaction tank, in particular to a jet aeration biofilm reaction tank. Background technique [0002] At present, my country's rural sewage treatment has just started and is still in the exploratory stage. Due to the backward economy and low level of technical management in rural areas, it is not suitable to directly apply the urban sewage treatment model. Rural sewage treatment lacks low construction costs, low operating costs, and good treatment effects suitable for large-scale promotion, and lacks corresponding planning guidelines. At present, the sewage treatment technologies that are widely used in rural areas of our country mainly include: domestic sewage biogas digester technology, constructed wetland treatment technology, stabilization pond treatment technology and biofilm treatment technology. According to the main structure of the constructed sewage treatment facilities, rural sewage treatment facilities are ...
