Abstract

The invention provides a biological membrane processing device used for processing black water. The biological membrane processing device comprises a biological reaction tank, wherein a biological rotary disc is arranged inside the reaction tank, and the biological rotary disc comprises a rotating shaft, and a plurality of discs arranged on the rotating shaft; a gas guiding pipe is arranged insidethe rotating shaft, and a plurality of aeration pieces are arranged on the rotating shaft; the aeration pieces are arranged along the length direction of the rotating shaft, and are internally provided with aeration pipes; the gas guiding pipe is communicated with the aeration pipes, and the upper surfaces of the aeration pieces are provided with multiple aeration holes communicated with the aeration pipes. The multiple aeration pieces are arranged on the rotating shaft, so that sufficient aeration can be realized.

Description

technical field [0001] The invention relates to a biofilm treatment device for controlling black water. Background technique [0002] In the prior art, the biological turntable process is a kind of biofilm sewage biological treatment technology, which is the artificial reinforcement of sewage irrigation and land treatment. It grows and breeds on the filler carrier of the biological turntable to form a film-like biological sludge—biofilm. [0003] As a bioreactor for aerobic treatment of wastewater, the biological turntable can be said to have emerged with the popularity of plastics. The reactor is composed of a water tank and a set of discs: dozens or nearly a hundred pieces of plastic or fiberglass discs are connected by shafts and placed flat on the surface of a bar-shaped tank with a semicircular cross-section. The diameter of the disc is generally no more than 4 meters, and the diameter of the groove is about a few centimeters larger. There is a motor and a reduction d...
