Abstract In order to culture the cell of the microbe and flora or fauna, under the environment of rich nutrition,high density,rich dissolved oxygen,and high viscosity,a new 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 are studied,the best air distribution is chosen.The result indicate that this kind of membrane bioreactors can 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 can be widely used in medium and small-sized reactor.bioreactor;membrane;admixture;air rate;energy save
