Experimental Disquisition of Membrane Aeration Bioreactor

摘要

In order to culture the cell of the microbe and flora and fauna, under the environment of rich nutrition, high density, rich dissolved oxygen, high viscosity, a new style membrane aeration bioreactor is developed. The key part is the distribution of membrane aeration bioreactor. The flow characteristic, pressure reduction, air-contained rate for the reactor which assembled many kinds of air distribution, the best air distribution is chosen. The result indicate: this kind of membrane bioreactor could generate homogeneous air bubble, have high rate of oxygen supply, have good nature of blending and have no mechanical shear damage on mediator. Compared to mechanical string membrane bioreactor, the reactor can save about half of electric energy and it can be widely used in mediums and small-size reactor.
