摘　　要：沼气脱硫是能源高效利用的重要组成部分。较成熟的干法及湿法脱硫已在工业上应用较多,重点介绍了生物脱硫的研究发展现状。生物脱硫通过微生物作用将硫化物转化成单质硫予以脱除,能耗低且无二次污染,具有极好的发展前景。另外对现有的单质硫回收方法也进行了简要概括。Biogas desulfurization is an important part of the effective fuel utilization. Based on the comparatively mature desulfurization technology contained dry and wet desulfurization in industry application, the research and development slatus of biological desulfurization was emphatically introduced in this paper. With biological desulfurization, sulfide was transformed into sulfur by microorganisms and removed. This technology would have excellent prospects for development with low energy consumption and no secondary pollution. In addition, the existing recovery technology of element sulfur was briefly summarized.
