Combined type biological rotating disk processing device

Abstract

The invention discloses a combined type biological rotating disk processing device. The combined type biological rotating disk processing device comprises a filter screen, a rotating disk fixing sleeve shell, a rotating shaft, a rotating disk roller, a rotating disk bacterial strain continuous supply device, a rotating disk pedestal, and an outlet; the bottom end of the filter screen is embedded into the top end of the rotating disk fixing sleeve shell; one end of the rotating shaft close to the filter screen is embedded at the axis center of the bottom end of the rotating disk fixing sleeve shell; the bottom end of the internal part of the rotating disk fixing sleeve shell is fixedly provided with the rotating disk pedestal. In using process, a forward centrifugation bacterial strain culture mechanism and a backward centrifugation bacterial strain culture mechanism are driven to perform positive and negative rotation using the rotating shaft, centrifugation force is generated by weight blocks in the forward centrifugation bacterial strain culture mechanism and the backward centrifugation bacterial strain culture mechanism under the driving effect of a cover plate, so that the forward centrifugation bacterial strain culture mechanism and the backward centrifugation bacterial strain culture mechanism rotating in opposite directions are used for intermit supply of sewage with high purity microbial strains, bacterial strain density is ensured, and the purifying requirements of each batch of sewage are satisfied.

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.
