摘　　要：生物燃气具有清洁、高效、安全和可再生四大特征,在替代和补充天然气方面具有巨大潜力,正成为我国新能源战略的拓展方向之一.生物燃气的高值利用是推进产业化应用的重点,脱硫环节直接影响设备运行、产品品质和工程质量.与传统的脱硫工艺相比,生物脱硫具有效率高、无二次污染、处理成本低等优点,是新的研发热点和产业化应用方向之一.本文综述了生物燃气生物脱硫的基本原理、主要菌种、工艺过程、工程案例等最新研究与应用情况.重点对化能营养型硫细菌的生理生化特性及其脱硫性能进行了综合比较分析,并对它们基于生物洗涤塔原理的两段式沼气脱硫工艺的应用案例进行剖析.最后,对我国发展生物脱硫技术和工程应用提出了深入研发高效工艺、实现生物燃气产业化的建议.With the advantages of cleanliness, efficiency, safety, and renewability, biogas as an alternative and complementary natural gas is becoming the new direction of energy development strategy of China. Biogas desulfurization is one of the key points for biogas high-value utilization and industrial application. The desulfurization process directly impacts equipment operation, product quality and engineering quality. Compared with the traditional desulfurization process, bio-desulfurization has high efficiency, no secondary pollution and low cost, therefore a research hot spot and industrial application for biogas desulfurization. This paper reviews the basic principles ofbio-desulfurization, main effective bacteria, desulfurization process, project cases and the latest research and application. The major emphasis of this review is the comparison analysis of the physiological and biochemical characteristics of chemotrophic bacteria, and their desulfurization performance. It also lays emphasis on the application case of two-stage biogas desulfurization process based on the bioscrubber. At last, this review puts forward suggestions on development of bio-desulfurization technology and industrialization in China, including making further technological innovation, doing in-depth research of bio-desulfurization process, as well as increasing the number and expanding scale of engineering applications.
