Fe^(3+)离子催化与微生物代谢在烟气脱硫中的协同作用

THE COOPERATIVE EFFECT OF Fe^(3+) CATALYSIS AND MICROOGANNISM METABOLISM ON FLUE GAS DESULFURIZATION

在酸性条件下(pH=2.0~2.8),Fe3+对SO2显示了良好的催化氧化作用。Fe2+对反应有较强的抑制作用。电院微生物1在其繁殖过程中,以Fe2+为能源,能有效地将Fe2+转化为Fe3+。将这一功能与上述反应相结合,能够维持Fe3+浓度,使反应持续进行。

Under the acid condition (pH=2.0～2.8),Fe 3+ has a good catalysis oxidation to SO_2;whereas Fe 2+ has inhibition to this reaction.DYB1(Dian Yuan Bacteria 1)in the course of breeding it with Fe 2+ as the energy can turn Fe 2+ into Fe 3+ effectively.Combining this function with the above-mentioned reaction can keep on the constant concentration of Fe 3+ and maintain circulation of desulfuration.
