摘　　要：首先进行了脱硫微生物的培养以及粉煤灰上清液的制备。通过正交实验获得了粉煤灰的最佳浸泡条件 ,以获得最大浓度的Fe3 +离子。并在内径为 65mm ,高 1 5 0 0mm的有机玻璃实验台上进行了冷态脱硫实验 ,研究了不同吸收液、pH值、气液比对脱硫效率的影响。结果显示 ,在相同的条件下 ,粉煤灰上清液的脱硫效率高于蒸馏水 ;加入Fe3 +的吸收液脱硫效率高于粉煤灰上清液 ;加入Fe3 +,同时加微生物DYB1脱硫效率最高。气液比相同时 ,加入微生物DYB1的Fe3Two kinds of microbe were cultivated for the biochemical desulfurization. Through the experimental research the optimum condition for the dialysis of fly ash was found: the concentration of Fe 3+ are highest when the fly ash are dipping in the solution (pH value is 4.5, ratio of solid to liquid is 1∶40 and DYB1 microbe are added) for eight hours. The influences of the dialyzing solution of fly ash, the concentration of Fe 3+ and ratio of gas to liquid on the SO 2 retention efficiencies were considered. The results showed that under the same ratio of liquid to gas and pH value: if Fe 3+ was added to the solution, the SO 2 retention efficiency increased; if the Fe 3+ and microbe are added to the solution at the same time, the desulfurization efficiency is highest among the three solutions.
