摘　　要：试验研究了利用氧化亚铁硫杆菌和Fe离子协同脱除烟气中的SO2,考察了液气比、反应温度、初始Fe2+浓度等因素对脱硫效率的影响,研究表明氧化亚铁硫杆菌和Fe3+体系对SO2具有循环催化氧化吸收的作用,并且提高初始Fe2+浓度,保持适宜的温度(30℃～40℃),有利于维持此循环效果而得到持久高效的脱硫效率。The Thiobacillus ferrooxidans and Fe ions were used for removing the sulfur dioxide from flue gas. The experiment were taken for examines the effect of the liquid gas ratio, reaction temperature,initial Fe2＋＇ concentration on desulfurization efficient. The results indicated that Thiobacillus ferrooxidans and Fe3＋ system had cyclic catalytic oxidation absorption effect on sulfur dioxide,and can improve the initial concentration of Fe-2＋ ,maintain appropriate temperature （30℃～40℃）, is conducive to maintaining the circulation effect and reaching a high desulfurization efficient.
