Abstract:
A bench-scale removal experiment of mixed gas containing hydrogen sulfide and benzene is carried out by using biotrickling filter. The effect of inlet concentration, spray water amount and shock loading on the removal efficiency are investigated. The results show that removal efficiency of hydrogen sulfide is higher than 92. 6% when its inlet concentration is lower than 213 mg /m3 . The removal efficiency of benzene is higher than 37% when its inlet concentration is lower than 34 mg /m3 . Removal efficiency of hydrogen sulfide is not affected by benzene when the inlet concentration of benzene is lower than 38. 4 mg /m3 . The mixed gases have the higher removal efficiency when the spray water is 6. 7 ~ 12 L /h. The results show that the biotrickling filter has strong ability to resist shock loading,being easily operated and realized.
