Novel biological rotating disc

Abstract

The invention discloses a novel biological rotating disc. The novel biological rotating disc comprises a fixed support, a sewage inlet, a clear water outlet, a sewage tank and a disc, wherein the fixed support is provided with a support flange, the disc is arranged on the fixed support, a rotating disc shaft with a driven wheel is arranged at the center of the disc, a motor and a speed reducer are arranged outside the sewage tank, the speed reducer is used for driving the rotating disc shaft to rotate through a driving wheel, a driving chain and the driven wheel of the rotating disc shaft, the disc is a full circular body composed of n fan-shaped sheet bodies with angles of 360 degrees / n (n is an even number) which are combined together, each fan-shaped sheet body comprises a disc side, a disc support part for connecting the disc side and the center and a reticulate structure for growth of a biological membrane, a disc fixing part is arranged at the joint of the disc support part and the disc side, and a fixing hole is arranged in the middle part of the disc support part. The novel biological rotating disc is simple in structure and low in energy consumption, occupies a small space, is free of noise due to no use of a draught fan for aeration, hardly generates odor and has good practicability. The sewage treatment efficiency of the novel biological rotating disc can be effectively improved.

Description

technical field [0001] The invention belongs to the field of organic wastewater treatment in sewage treatment engineering, and in particular relates to a novel biological turntable. Background technique [0002] The biological turntable is an earlier biofilm process for sewage treatment. At present, the discs of domestic biological turntables are basically flat discs or corrugated discs. The discs of biological turntables have disadvantages such as small specific surface area, poor film-hanging and releasing performance, low processing efficiency, and large floor space. Has not been widely promoted and applied. Although the original biological turntable has many advantages such as low noise (no blower is used) and low odor, its large-scale use is limited by the disadvantages of large footprint, high energy consumption, and low efficiency. Contents of the invention [0003] In order to solve the above problems, the object of the present invention is to provide a new type ...
