Abstract
A fluidized bed bioreactor including microbial consortium was used to remove benzene and toluene simultaneously. The microbial consortium was obtained from sewage treatment plant, and showed maximum benzene degradation rate of 45.2 mg/lㆍhㆍmg cell in 30 ℃ and pH 7.0, and maximum toluene degradation rate of 44.4 mg/lㆍhㆍmg cell in 30 ℃ and pH 8.0. The optimum operating condition of the fluidized bed bioreactor was 30 ℃, pH 7.0 and 150 cm of liquid bed height. The average removal efficiency of benzene was 94% for inlet concentration of 53(±5)_x000D_
ppm benzene and that of toluene was 96% for an inlet concentration 48(±5) ppm toluene at 600 l/h of gas volumetric flow rate. The maximum removal capacity in the experimental condition was 22.3 g/m(3)ㆍh for benzene and 16.3 g/m(3)ㆍh for toluene.
