Combined biological turntable processing device

Abstract

The invention discloses a combined biological turntable treatment device, the structure of which comprises a filter screen, a turntable fixed casing, a rotating shaft, a turntable roller, a turntable strain continuous supply device, a turntable base, an output port, and the bottom end of the filter screen is installed in an embedded manner. Inside the top of the turntable fixed casing, the end of the rotating shaft close to the filter screen is installed at the axial center of the bottom end of the turntable fixed casing by embedding, and the bottom end of the turntable fixed casing is fixedly installed with a turntable base. The seed culture mechanism and the reverse centrifugal strain culture mechanism, under the forward and reverse action of the rotating shaft, are driven by the cover plate to generate centrifugal force through the action of the gravity block set inside itself, so that the two opposite direction strain tanks are intermittently The sewage is supplied with high-purity microbial strains to ensure the density of the strains to meet the purification requirements of each batch of sewage.

Description

technical field [0001] The invention relates to the field of biological turntables, in particular to a combined biological turntable processing device. Background technique [0002] The biological turntable is an efficient and economical sewage biological treatment equipment developed on the basis of the biological filter. The biological turntable is a biological treatment structure composed of a tank and a rotating disk partially submerged in sewage. The microorganisms growing on the surface of the disk The membrane repeatedly contacts the sewage in the tank and the oxygen in the air to purify the sewage. [0003] The existing biological turntables mainly purify sewage through internally cultivated microbial strains. When the frequency of sewage purification needs to increase, the microbial strains inside the biological turntable in the purification tank will be carried along with the discharge of sewage. As a result, its density is reduced, and the reduction of the densit...

Problems solved by technology

[0003] The existing biological turntables mainly purify sewage through internally cultivated microbial strains. When the frequency of sewage purification needs to increase, the microbial strains inside the biological turntable in the purification tank will be carried along with the discharge of sewage. As a result, its density is reduced, and the reduction of the density of the purified bacteria will make it difficult for the next batch of sewage to obtain the purification requirements based on the standard line.
