Experiment research of Thiobacillus ferrooxidans used for flue gas desulfurization

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 Fe2+,maintain appropriate temperature(30℃~40℃),is conducive to maintaining the circulation effect and reaching a high desulfurization efficient.
