【 摘 要 】
The oxygen mass transfer characteristics in a Micro-Pressure Inner-Loop bioreactor (MPR) were studied by clean water oxygenation experiment, the results show that when the aeration adopt by 0.1, 0.2, 0.4, 0.6 m3•h-1, respectively, the oxygen mass transfer coefficient KLa(20) in the reactor increases with the increase of the aeration. KLa(20)shows a good linear correlation with the aeration. The rate is 0.2128 h•m-3•min-1 and the correlation coefficient R=0.993. However, the trend of EO2increases first and then decreases with the increase of aeration. When the aeration increased to 0.4 m3•h-1, the EO2reaches the maximum. If aeration increases constantly, EO2begin to decrease excessive aeration may lead to an increase in energy waste during reactor operation.
