Abstract: SO2 removal experiment is conducted on a biological desulfurization simulation device.The results show that temperature has a significant effect on the system's desulfurization efficiency,with a maximum efficiency appearing at around 30℃.As the concentration of inlet gas increases,the desulfurization load of the biological desulfurization system increases gradually,and the desulfurization efficiency is decreasing continuously.As the ratio of gas-liquid increases,the absorption efficiency drops,and the optimal gas-liquid ratio is 30:1.Desulfurization efficiency and sulfate yield both increase with the increasing aeration,and sulfur yield increases first and decreases then with the increase of aeration.Controlling ORP value can improve effectively the yield of elemental sulfur.The generation rate of elemental sulfur can exceed 91.5% when ORP is controlled between -300 mV and -200 mV.
