摘　　要：研究了泥炭和接种活性污泥的泥炭作为填料的生物过滤器去除甲硫醚 (DMS)恶臭气体的情况 ,确定了生物过滤器中降解DMS的优势微生物种群。填料是原始泥炭的生物过滤器几乎不能去除DMS ,接种活性污泥的泥炭生物过滤器则能有效地去除低浓度DMS气体。去除DMS适宜的pH值范围是 7～ 5 45。微生物学分析表明 。The removal characteristics of dimethyl sulfide (DMS) with a peat biofilter were studied The peat itself did not remove DMS The peat inoculated with activated sludge as a source of microorganisms showed an efficient removal of DMS The optimum pH of DMS removal by the biofilter was 7～5 45 Dominant microorganisms for degradation of DMS in the peat biofilter were some chemolithotrophic and non acidophilic sulfur oxidizing microorganisms originating from sludge
