| 摘 要： | The Bacillus firmus was immobilized into Ca-alginate beads according to the different initial biomass concentration, calcification time and activation time.Three types of immobilized Bacillus firmus beads were packed respectively in trickling biofilter to purify xylene contained waste gases,and the performance of immobilized-cell biofilter was compared with traditional biofilm attached biofilter packed with two types of ceramic pellets.The results showed that three types of immobilized beads had different capabilities for removing xylene and life-spans.Higher initial biomass in immobilized beads resulted in better performance but shorter life-span.Activation process can remarkably enhance the activity of bacteria,and the removal efficiency of xylene can substantially be improved.Calcification time had influence on life-span of immobilized beads.Without acclimation,the cell-entrapped biofilter can obtain the maximum elimination capacity of 92.4 g/(m~3·h).However,compared with biofilm attached biofilter,it has a poorer intrinsic drawback in volatile organic compounds (VOCs) removal due to the existence of excess mass transfer resistance.

| Abstract: | The Bacillus firmus was immobilized into Ca-alginate beads according to the different initial biomass concentration, calcification time and activation
time. Three types of immobilized Bacillus firmus beads were packed respectively in trickling biofilter to purify xylene contained waste gases, and the performance of immobilized-cell
biofilter was compared with traditional biofilm attached biofilter packed with two types of ceramic pellets. The results showed
that three types of immobilized beads had different capabilities for removing xylene and life-spans. Higher initial biomass
in immobilized beads resulted in better performance but shorter life-span. Activation process can remarkably enhance the activity
of bacteria, and the removal efficiency of xylene can substantially be improved. Calcification time had influence on life-span
of immobilized beads. Without acclimation, the cell-entrapped biofilter can obtain the maximum elimination capacity of 92.4
g/(m3·h). However, compared with biofilm attached biofilter, it has a poorer intrinsic drawback in volatile organic compounds (VOCs)
removal due to the existence of excess mass transfer resistance.
