%X The characteristics of gas-liquid mass transfer of three-phase system comprising air, tap water/wastewater, and hollow glass beads were studied in a laboratory-scale inverse turbulent bed reactor. The influence of operational factors and liquid property on volumetric liquid-phase mass transfer coefficient kLa was investigated under the conditions of superficial gas velocity (0.53mm xs(-1) - 10mx s(-1) solid hold-up (0 - 0.3), and superficial liquid velocity (0 - 0.2mm x s(-1)). The results showed that the coefficient value was 0.0456 - 1. 414min -, which increased with superficial gas velocity and liquid velocity. The coefficient attained the maximum value at solid hold-up of 0.05 - 0.08. Compared with the coefficient value in tap water, that in synthetic wastewater and industrial wastewater is decreased by 39.0% and 50.9%, respectively. These data have provided a basis for the process analysis and mathematical simulation of inverse turbulent bed reactor.
