چکیده انگلیسی
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 (0.53-10 mm·sâ1), solid hold-up (0-0.3), and superficial liquid velocity (0-0·2 mm·sâ1). The results showed that the coefficient value was 0.0456-1.414 minâ1, 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, the one 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 the inverse turbulent bed reactor.
