Abstract: The article a analysis of the existing mathematical models of airlift bioreactors-clarifiers have been presented. The design and principle of operation of the investigated biological wastewater treatment facility are presented. A brief review of the application of computational fluid dynamics programs for the theoretical study of the motion of liquid and water-air flows in airlift biological reactors is carried out. Hydrodynamic parameters of flows in the airlift bioreactor-clarifier were calculated by a software package «FlowVision». The results of calculations in the absence of a load on the clarifier and a circulation rate of 200 m3/(m2·h) for various semi-empirical turbulence models are presented: standard «k-e» model, «quadratic k-e» model, SST-model, «k-e FlowVision» model. Has been determined the semi-empirical turbulent model, which most accurately characterizes the parameters of the eddy zone of the airlift bioreactor-clarifier.
Keywords: airlift bioreactor, clarifier, computational fluid dynamics, turbulence model, waste water treatment.
