【Abstract】 Biofiltration technique for treating H 2S-contaminated gas streams was investigated. The effects of retention time and volumetric mass loading on H 2S removal efficiency, the ability of biofilter to buffer shock loading of the peat biofilter and removal kinetics were studied. The results showed that when the gas retention time was 30*!s, the H 2S removal efficiency was higher than 99%, and the reactor was robust enough to recover reasonably quickly in a shock loading scenario.更多还原
