摘　　要：介绍一种氧化亚铁硫杆菌脱除SO2 的新工艺。并研究铁离子浓度、液气比和气体SO2 浓度等对脱硫效率的影响。对比实验表明细菌菌液比稀硫酸吸收法的脱硫效率更高。在细菌菌液的脱硫作用中 ,不仅铁离子 ,而且细菌本身也起到关键作用。实验结果表明利用微生物脱除气体中的SO2This paper describes a new desulphurization process with Thiobacillus ferrooxidant.The effects of the concentration of ferric inos,the ratio of liquid to gas and the concentration of SO 2 etc on the desulfuration efficiency have been studied.Compared with the method of diluted sulfurous acid absorption,the ability of desulphurization by the bacterial solution is more efficient.Not only the ferric inos,but also the bacterial cells play a key role for SO 2 removal.Such results showed that the removal of SO 2 in a gas by microorganisms is practicable.
