Abstract

The invention relates to a biological rotating disc. The biological rotating disc comprises a contact reaction tank, a rotating shaft and a plurality of microporous disc sheets, wherein the two ends of the rotating shaft are separately rotatably arranged on a first end face and a second end face, which are opposite, of the contact reaction tank, the microporous disc sheets are sequentially fixed to the rotating shaft along a length direction of the rotating shaft and are of radiating arrangement in a cross section direction of the rotating shaft, disc faces of the microporous disc sheets are all arranged parallel to the rotating shaft, and the rotating shaft is connected with a driving device. According to the biological rotating disc disclosed by the invention, microbes and activated sludge are high in adhesive power, the microbes and the activated sludge in the disc are high in growth quality, and the sewage treatment efficiency is high.

Description

technical field [0001] The invention relates to the field of sewage treatment technology and equipment, in particular to a biological turntable. Background technique [0002] The biological turntable process is a kind of biofilm sewage biological treatment technology, which is an artificial enhancement of sewage irrigation and land treatment. This treatment method makes microbes such as bacteria and fungi, and micro-animals such as protozoa grow and breed on the filler carrier of the biological turntable to form a film-like biological sludge—biofilm. After primary treatment in the sedimentation tank, the sewage is in contact with the biofilm, and the microorganisms on the biofilm absorb the organic pollutants in the sewage as nutrients to purify the sewage. [0003] In the existing process of treating environmental sewage with a biological turntable, a plurality of coaxial circular discs are usually rotated around the rotation axis to attach microorganisms and then adsorb a...
