Flow Field Numerical Simulation on the Membrane Aeration Biofilm Reactor
Abstract:
Based on the design of membrane bioreactor three-dimensional finite element model is established,Finite volume method was applied to sewage treatment in the process of membrane bioreactor internal flow field is unsteady flow numerical simulation and analysis. The results of numerical simulation can be seen at the bottom of the membrane module speed change is small, to purify sewage full contact with membrane module, the upper change is bigger, treated sewage can be quickly exhaust to the outside world. This study on flow field of the bioreactor of in-depth study, the new structure design and optimization has its far-reaching significance.
