    Abstract:

    Rotating packed bed(RPB) was applied in adsorption removal of phenol from simulation wastewater, with the activated carbon as adsorbent. The influence of operating parameters of RPB on removal efficiency such as high gravity factor, flow rate and initial concentration of phenol wastewater were examined to determine the optimum operating conditions. The pseudo-first-order model and the pseudo-second-order model were used to study the adsorption kinetics. The effect of operating parameters on the adsorption rate constant were studied. The removal efficiency and adsorption rate constant were compared with those of traditional adsorption method. Results show that under the operational conditions: high gravity factor of 44.68, flow rate of 35 L·h-1, initial concentration of phenol wastewater of 1000 mg·L-1, the adsorption time of 2 h, the removal efficiency of phenol can reach maximum about 90%, which is 30% higher than the traditional adsorption method. The adsorption rate constant obtained by pseudo-second-order model increases with the increasing of high gravity factor and flow rate. The kinetics equations in RPB and traditional adsorption method under the optimum condition are as follows: t/qt=0.02648+0.77932t, t/qt=0.02869+1.55707t, and the adsorption rate constant improves from 5.28×10-4 to 9.02×10-4.
