在我们的前期工作中，一种新型的转鼓生物反应器（RDB）的体积为18 L和96 L，显示了高固体浓度的生物浸出过程的潜力。本文对容积为703 L的大型RDB进行了放大，考察了96 L和703 L RDB的操作条件和挡板参数对功耗的影响。结果表明，比功耗随转速的增大而增大，对曝气量的变化不敏感。同时，比功耗与负载系数呈负相关，与RDB直径呈正相关。结果表明，随着挡板数量和挡板宽度的增加，功率消耗也随之增加。当703 L RDB配备8个0°折流板时，传质性能最经济。在相同的比功率下，703 L RDB的传质性能接近于商业上使用的搅拌槽生物反应器（STB）。对于Al 2 O3料浆系统，703 L RDB的比功耗小于相同直径的传统STB的1/3。
A novel rotating drum bioreactor (RDB) with the volume of 18 L and 96 L in our previous work has shown the potential for bioleaching processes with high solid concentration. In this paper, a larger RDB with a volume of 703 L was scaled up, and effect of operation condition and baffle parameters on power consumption in the 96 L and 703 L RDBs was investigated. The results showed that the specific power consumption increased with the rotation speed and was insensitive to aeration rate. Meanwhile, the specific power consumption was negatively related to loading coefficient and was positively related to diameter of RDB. It was found that the power consumption increased with the increase of number and width of baffles. The mass transfer performance was most economic, when the 703 L RDB was equipped with 8 baffles with a 0° angle. The mass transfer performance of the 703 L RDB at the same specific power was close to that of a stirred tank bioreactor (STB) commercially used. For the Al2O3slurry system, the specific power consumption in the 703 L RDB was less than 1/3 of that in the traditional STB with the same diameter.
