摘　　要：我国大气污染的主要污染物是烟尘(TSP)、SO2和NOx,其中以SO2对环境的污染最为严重。因此,发展洁净煤技术降低煤炭使用过程中对环境的污染迫在眉睫。分析了煤中硫的形态及存在方式,比较了煤的燃前脱硫、燃烧中固硫和燃烧后烟气脱硫技术,介绍了煤的微生物预处理浮选脱硫技术的原理,阐述了国内外对该技术的研究现状,指出了研究中存在对微生物在黄铁矿颗粒表面的吸附和改性机理研究不够深入、缺少工业应用等问题,指出广泛引入微生物学等其他学科理论及技术,积极推广工业应用。In China,TSP,SO2 and NOx were the main pollutant. Among them,SO2 was the most serious pollutant. Since most of SO2 was from coal combustion,so developing clean coal technology was extremely urgent. The sulfur speciation and existence in coal was intro-duced. The desulfurization technologies before combustion,sulfur solidifying technologies during combustion and flue gas desulfurization were compared. The mechanism and application of coal desulfurization by microbial pretreatment and flotation separation was introduced. On the surface of pyrite particles,the research of adsorption and modification mechanism of microorganisms was still not deep,there were also no referable industrial application examples. So the introduce of microbiology theory and technology,relevant industrial application pro-motion were the main measures.
