Abstract: The principles, application and industrialization of biological desulphurisation methods are reviewed including biological filtering, biological trickling and biological scrubbing. At the same time, related researches on the biotreatment of H2S containing gas by using these biological desulphurisation methods are described. These biotreatment methods have been widely used in industry out of China for the purification of H2S containing gases such as natural gas, synthetic gas and fuel gas as well as and from ethylamine is made to absorb renewable process acid gas desulphurization. Mortherland relatively mature，industrial application instance has many been realized preliminary，such as emission desulphurisation，wet desulphurisation loop fluid circulation and regeneationzaisheng，etc. With Compared with mature development of the physical and chemical methods, the biological compared to the biochip method has its special superiority，such as low - cost，second pollution small，and so on.

摘要： 综述了生物过滤法、生物滴滤法和生物洗涤法3种生物脱硫方法的原理、应用特点及工业化情况。同时介绍了3种生物脱硫方法用于处理含H2S气体的国内外研究状况。国外在该方面研究较成熟，已实现多领域、多种含H2S气体净化的工业应用，如天然气、合成气、燃料气和来自胺吸收再生过程酸性气体的脱硫；国内起步晚，初步实现了工业化应用，如废气脱硫、湿法脱硫循环液再生等。与发展成熟的物理法和化学法相比，生物法有其特殊的优越性，如成本低、二次污染小等。
