新型气力搅拌式生物反应器的实验研究
Experimental study on new pneumatic stirring bioreactor
摘要
Abstract
In order to culture the cell of the microbe and flora or fauna, a new membrane bioreactor was developed.The microporous rubber membrane was used for lowering the stirring shear force to meet the stirring demand for the fluid media with rich dissolved oxygen, high density and high viscosity. In this experiment, the flow characteristic,pressure loss, gas holdup and dissolved oxygen mass concentration for the reactor were investigated, and the microporous rubber membrane with better comprehensive properties was selected. The result indicates that this kind of membrane bioreactor is featured by homogeneous air bubble, high rate of oxygen supply, good properties of blending and no mechanical shear damage on the liquid medium in the reactor. Compared with the conventional mechanical string membrane bioreactor, the reactor has obvious advantages and can be widely used in the mediumsize and small-size reactors that have higher requirement for the shear properties of medium.关键词
