摘　　要：研究了低浓度软锰矿浆与氧化亚铁硫杆菌(Thiobacillusferrooxidans,简称T.f)联合吸收SO2过程中软锰矿浆浓度、T.f菌液量、O2体积分数、气体流量以及SO2进口浓度对硫酸根生成的影响。研究表明:在该体系中,生成的硫酸根浓度随着软锰矿浆浓度、T.f菌液量、O2体积分数以及气体流量的增加而增大;随着进口SO2浓度的增加,硫酸根的生成呈现先增加后减少的趋势。Factors such as the concentration of pyrolusite slurry,the amount of T.f,the percent of O_2(volume),the flow of gas and the inlet concentration of SO_2,that influenced on production of SO_4^(2-) in the absorption of SO_2 by low concentration pyrolusite slurry and Thiobacillus ferrooxidans were studied in this paper.It showed that the production of SO_4^(2-) was enhanced in pace with the increase of the concentration of pyrolusite slurry,the amount of T.f,the percent of O_2 (volume),the flow of gas,and that with the increase of the inlet concentration of SO_2,the concentration of SO_4^(2-) was increased at first and then decreased.
