Problems solved by technology

Most of the currently used biological turntable discs are made of corrugated plastic plates, glass steel plates, etc. The discs have a single shape, small specific surface area, poor film-forming performance, low processing efficiency, and short service life. Therefore, a large specific surface area is found. Disc materials with good performance, light weight and corrosion resistance are a main direction of current RBC research

Embodiment Construction

[0025] The biological turntable directly uses chitosan fiber net to make a cage instead of a disc, and adds modified peanut shell filler in the cage, the biofilm can be fixed on the surface of the filler and the cage, and the lower half of the cage is immersed in water. As the rotating cage rotates, the carrier and the biofilm on the rotating cage are alternately exposed to air and submerged in water to achieve the purpose of oxygenation and wastewater treatment. Chitosan fiber is made of chitosan as the main raw material, dissolved in an appropriate solvent, prepared into a certain concentration of spinning stock solution, and then processed by spinning, coagulation forming, stretching and other processes to obtain high molecular weight with a certain strength. functional materials. The modified peanut shell filler is to wash the peanut shells with tap water and deionized water, dry, crush, and sieve to make peanut shell particles between 300 μm. The above peanut shell parti...

Abstract

The invention discloses a biological rotating disk treatment method for synthetic leather wastewater. A biological rotating disk is directly manufactured into a rotating cage through a chitosan fiber web to replace a disk, and peanut shell filler is fed into the rotating cage. A biological membrane can be fixed to the surfaces of the filler and the rotating cage, a lower half portion of the rotating cage is immersed in water and rotates along with the rotating cage, the biological membrane on a carrier and the rotating cage is alternatively exposed in air and immersed into water, and a purpose of oxygenating and treating wastewater are achieved. A reactor has the advantages of simple equipment, easiness to manufacture, small invest cost and the like.

Description

technical field [0001] The invention belongs to the technical field of synthetic leather wastewater treatment, and in particular relates to a biological turntable treatment method for synthetic leather wastewater. Background technique [0002] The biological turntable method (RBC) has a history of more than 50 years in treating sewage / wastewater. It is a kind of biofilm method for treating wastewater. It was developed on the basis of biological filters and has been widely used in various domestic sewage. and industrial wastewater treatment. [0003] The biological turntable is composed of a series of discs installed on the horizontal shaft. The wastewater enters the oxidation tank at a certain flow rate, and the discs are partially submerged in water (about 40%-45%). When the speed rotates in the tank, the microorganisms adsorbed on the disc contact with the organic matter in the waste water and the oxygen in the air alternately, and carry out facultative anaerobic and aero...
