摘要: 从污水处理厂二沉池分离获得一株硫酸盐还原菌厌氧菌株，依据生理生化分析和16S rDNA基因序列测定该菌株被鉴定为脱硫脱硫弧菌（Desulfovibrio desulfuricans）。在气体吸收的双膜理论和液相中微生物转化的米门方程基础上，建立了搅拌式生物吸收反应器中脱硫脱硫弧菌净化二氧化硫气体的动力学模型，并求解出相应的动力学参数基质转化最大速度Vmax和米氏常数Km，实验结果所得到的线性方程相关性较好，线性相关系数可以达到0.998，而且脱硫脱硫弧菌吸收液具有较高转化二氧化硫的能力。

Abstract: An anaerobic strain of sulfate-reducing bacteria was isolated from the sludge in secondary sedimentation tank of a sewage treatment plant. According to the analysis of physiological and biochemical measurements and its 16S rDNA gene sequence， the strain was identified as Desulfovibrio desulfuricans. The kinetic model for sulfur dioxide purification by Desulfovibrio desulfuricans in a stirred bioreactor was established based on the double film theory and the monod kinetic equation. The maximum convert rate of the medium and saturation constant were also calculated. The linear equation acquired from the experiment had good correlation and the linear correlation coefficient was 0.998. Desulfovibrio desulfuricans absorption liquid has high ability to treat SO2.
