Stepped biological rotating disc process system

Abstract

The invention discloses a stepped biological rotating disc process system. The stepped biological rotating disc process system comprises a chassis module and a plurality of biological rotating disc units, which are assembled, the chassis module comprises a base and inserting footstands, every biological rotating disc unit comprises an oxidation tank, a shaft rod and a rotating disc, bearing assemblies are arranged at the upper parts of two ends of the oxidation tank, shaft rods are mounted at two ends of the oxidation tank through the bearing assemblies, the rotating discs sleeve the shaft rods and are distributed at equal intervals relative to the shaft rods, connecting columns are welded to two sides of the lower portion of the outer end face of the oxidation tank, connecting screws arewelded to two sides of the upper portion of the outer end face of the oxidation tank, gear discs are sleeved at one ends, located outside the oxidation tank, of the shaft rods, an overflow pipe is fixedly inserted in the middle of the front side of the oxidation tank, and a water tank with an open upper portion is welded to a part, located among the four inserting footstands, of the upper surfaceof the base. The system has the advantages of simple building process, easiness in operation, small occupied horizontal space, and facilitation of promotion and application.

Description

technical field [0001] The invention relates to the technical field of biological turntables, in particular to a step biological turntable process system. Background technique [0002] Biological turntable is a kind of biofilm sewage treatment technology, which was created by the former Federal Republic of Germany in the 1960s. It was developed on the basis of biological filters, also known as submerged biological filters. The process has the advantages of flexible system design, convenient installation, simple operation, reliable system, and low operating and operating costs; it does not require aeration or sludge return, which saves energy and can obtain higher The purification effect has been widely used in the treatment of various domestic sewage and industrial sewage. [0003] However, most of the existing biological turntables are tiled in the process of construction and use. Therefore, in the case of high standards for the treated water quality, the entire biological...

AI Technical Summary

Problems solved by technology

[0003] However, most of the existing biological turntables are tiled in the process of construction and use. Therefore, in the case of high standards for the treated water quality, the entire biological turntable will have the disadvantage of occupying a larger floor space.
