ROTATING BIOLOGICAL CONTACTOR APPARATUS & METHOD

摘要

A wastewater treatment facility with a rotating biological contactor ("RBC") that has a control system. The RBC sits in a tank that receives wastewater to be purified over which a reversible rotatable shaft is supported. One or more stages of rotating disk assembles progressively purify incoming wastewater. Each stage is oriented transversely to the shaft and has a plurality of disk assemblies. Each disk assembly has a number of disks that are sandwiched between end plates. Each of the disks comprises multiple concentric truncated pie-shaped segments. Posts extend from the front and back faces of the disks for stirring wastewater and for offering numerous sites to which biomass may adhere and be suspended in the wastewater or exposed to ambient atmosphere during rotation
