| 中文摘要 |
| 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 (Internal Airlift Loop Bioreactor with Cells Immobilized onto Ceramic Honeycomb Support,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 . |
| 英文摘要 |
| 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. |
