摘　　要：研究了组合式圆盘涡轮 (CDT)生物反应器在非牛顿流体体系中动力学及传氧特性 ,采用空气 羧甲基纤维素钠 (CMC)水溶液体系进行了冷模实验研究 ,拟合出氧传递系数方程。实验结果表明 ,该反应器氧传递性能优于传统的六平叶圆盘涡轮(DT) 。Dynamic mechanism and oxygen transfer properties of combined disc turbine (CDT) in non-Newtonian fluid system are studied. Equation of oxygen transfer coefficient is derived from experimental results based on air-carboxymethyl cellulose sodium salt aqueous system. Experiment results show that CDT bioreactor is superior to traditional disc turbine. CDT bioreactor is suitably used as a bioreactor in non-Newtonian fluid system.
