Description

Gear-driven biological rotating disc

Technical Field

The utility model relates to a gear drive biological rotating disc belongs to the biological rotating disc field.

Background

The biological rotating disc is a sewage treatment technology by a biomembrane method, and the process has the advantages of flexible system design, convenient installation, simple operation, reliable system, low operation and running cost and the like; does not need aeration and sludge backflow, saves energy, can obtain higher purification effect within shorter contact time, and is widely applied to the treatment of various domestic sewage and industrial sewage. The mechanism of purifying organic matters is basically the same as that of the biological filter, but the structure form is different from that of the biological filter.

The working principle of the biological rotating disc is as follows: the mechanism of forming, growing and degrading organic matter of the biological film is basically the same as that of the biological filter, and the main difference is that a series of rotating disc bodies replace fixed filter materials, and the biological film grows on a rotating disc. When the biological rotating disc rotates, sewage flows along the disc gaps in the reaction tank, and organic matters in the sewage are adsorbed by the biological film on the rotating disc. When the disc rotates away from the water surface, a layer of sewage film is formed on the surface of the disc layer, oxygen in the air is continuously dissolved into water and microorganisms absorb the dissolved oxygen, and adsorbed organic pollutants are oxidized and decomposed. Every time the disk turns for one week, the adsorption-oxygen absorption-decomposition process is carried out. The rotating disc continuously rotates, pollutants are continuously oxidized and decomposed, the biological membrane gradually becomes thick, and the aged biological membrane falls off under the action of water flow shearing force and is discharged out of the sedimentation tank along with sewage. The rotating disc also makes the sewage in the tank stir continuously to oxygenate, and the dropped biomembrane is in suspension state in the tank and continues to play a role in purification, so that the biological rotating disc has the function of an activated sludge pool.
