The biological turning disc is one organic wastewater treatment equipment, which process with microbial. It has combines touch-oxidation method, biological filtration tank method and active sludge method.
The turning discs are installed on the oxidation tank, and 45% of the area is emerged in the wastewater, under the driving force, the discs will turn in slow speed, and the biological membrane growing on the disc will adsorb the organics in the wastewater. And when the discs leave the wastewater, the microbial will touch the oxygen in the air, and will decompose the organics into water, harmless inorganic and gas.
