%X Using sawdust as filler, biofiltration technique for treating H2S-contaminated gas streams was investigated. The suitable technological conditions and removal kinetics were studied. The results showed that the multilayer biofilter had a higher removal rate of H2S than that of the single layer biofilter. The removal rate of H2S was higher than 90% when the inlet volumetric loading rate of H2S was below 153.2 g H2S/(m3·d). When the inlet hydrogen sulfide was lower than 70 mg/m3, the bottom layer which was 200 mm thick removed more than 50% of the total H2S removal. The biofilter worked well as the moisture content ranged from 50% to 60%.The removal kinetics were researched based on the Michaelis-Menten model, two kinetic parameters were Ks with a value of 22.5 mg/m3 and Vm with a value of 1 000 g H2S/(m3·d).
