Experimental study on the treatment of odor gas containing hydrogen sulfide by peat biofilter

摘要：研究了泥炭生物滤塔处理含低浓度H₂S恶臭气体的技术.实验考察并研究了气体停留时间和H₂S进气负荷对H₂S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25—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.

Abstract：Biofiltration technique for treating H₂S-contaminated gas streams was investigated. The effects of retention time and volumetric mass loading on H₂S 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 30s, the H₂S removal efficiency was higher than 99%, and the reactor was robust enough to recover reasonably quickly in a shock loading scenario.
