Abstract
The cage bio-reactor is a new high-efficient sewage treatment reactor. The flowing inside of reactor influences the sewage treatment effect of reactor so numerical simulation is adopted to analyze the flowing inside of reactor in an attempt to identify the factors that influence the effect of sewage treatment, and provides the data for the following structure optimization of bio-reactor. In this paper, a coupled dynamic mesh with two-phase flow is used to analyze the hydrodynamic characteristic of the rotating-cage bio-reactor; the computation results show that the air flow enters into the bio-reactor, and then it rises toward right, bumps into the cage wall with the anti-clockwise rotation, scatters, and forms two back-flows in the upper of the bio-reactor. The backflow center has the tendency to form cavity; however, under the central shaft, the air flow does not disperse, where the volume fraction of the gas phase is low.
