Abstract
|
|
|
|
A biofiltration system using activated carbon/polyurethane composite as solid support inoculated with Bacillus sp. was developed for treating a gaseous stream containing high concentrations of HS. The effects of operating condition such as the influent HS concentration and the empty bed contact time (EBCT) on the removal efficiency of HS were investigated. The biofilter showed the stable removal efficiencies of over 99 ％ under the EBCT range from 15 to 60 sec at the 300 ppmv of HS inlet concentration. When the inlet concentration of HS was increased, the removal efficiencies decreased, reaching 95 and 74％, at EBCTs of 10 and 7.5 sec, respectively. The maximum elimination capacity in the biofilter packed with activated carbon/polyurethane composite media was 157 g/m/hr.
