摘要
在鼓泡塔式 (BubbleColumns ,BC)和气升式循环 (AirliftLoop ,AL)生物反应器基础上 ,于内循环管中加装蜂窝陶瓷载体 ,开发出蜂窝陶瓷固定化细胞的气升式内循环生物反应器 (InternalAirliftLoopBioreactorwithCellsImmobilizedontoCeramicHoneycombSupport,IALBR CICHS) .采用示踪技术通过测定反应器的水力停留时间分布来考察上述 3种反应器的有效工作体积和反应器内走旁路流体的比例 .实验和理论分析表明 ,IALBR CICHS可大大提高反应器的有效工作体积 ,减少流体走旁路的比例 .
An internal airlift loop biorector with cells immobilized onto ceramic honeycomb support(IALBR CICHS)was developed based on the bubble columns(BC)and airlift(AL)bioreactor by installing a ceramic honeycomb support in the draught tube.Their hydrodynamics were respectively studied by the tracer element to determine their retention time distribution (RTD).Experiment and theory analysis indicated that the IALBR CICHS had more efficacious reactive volume rate( η )and less short circuit rate( λ )for fluid flow compared with the BC and AL bioreactor.
