  • In this study, the kinetic behaviors between acetone and composite bead were investigated. The microbial growth rate decreases with increasing the average inlet concentration and increases with increasing the operation temperature at the average inlet concentration ranging from 50 to 300 ppm and the operation temperature ranging from 30 to 40. The microbial growth rate would be inhibited as the average inlet concentration increases and the inhibitive effect is more pronounced at the higher operation temperature. The microbial growth rate would be enhanced as the operation temperature increases and the enhancive effect is more pronounced at the higher average inlet concentration. The value of maximum rate Vm and half-saturation constant Ks are range from 0.04 to 0.05 g-C/h-kg packing material and from 37.19 to 42.77 ppm, respectively. The biochemical reaction model could be regarded as the zero-order kinetic with the diffusion rate limitation. The biochemical reaction rate decreases with increasing the average inlet concentration and increases with increasing the operation temperature. The biochemical reaction rate would be inhibited at the high average inlet concentration and the inhibitive effect is more pronounced at the lower operation temperature. The biochemical reaction rate would be enhanced as the operation temperature increases and the enhancive effect is more pronounced at the higher average inlet concentration. The maximum elimination capacity of biofilter increases with increasing the operation temperature. The value of critical and maximum elimination capacity are ranging from 0.07 to 0.15 and from 0.13 to 0.16 g-C/h-kg packing material, respectively.
