摘　　要：研究了泥炭生物滤塔处理含低浓度H2 S恶臭气体的技术 .实验考察并研究了气体停留时间和H2 S进气负荷对H2 S去除率的影响 ,生物滤塔的抗冲击负荷能力以及生物降解宏观动力学 .结果表明 ,当停留时间为 2 5— 30s时 ,进气浓度为 3— 70mg m3 ,去除率达到 99%以上 ,且具有较强的抗冲击负荷 .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.
