%X Study on the gas holdup and oxygen transfer in a internal-circulation three-phase biofluidised bed (ITFB) with tap water was conducted. The results showed that oxygen transfer condition in a ITFB was better than that in a conventional three-phase biofluidised bed.When gas flux was low, the riser oxygen transfer coefficient K_(Lal) was greater than K_(la2) in downcomer, while, K_(La2) was greater than K_(La2) when gas flux was high. K_(La) increase with the increase of carrier concentration when the total amount of carrier was above 1. 6 kg.
