摘要: 为查明不同组合菌种预处理对褐煤转化生物甲烷的影响,选用白腐菌、假单胞菌和绿孢链霉菌两两组合对褐煤进行生物预处理和生物产气实验。通过生物产气检测、Gompertz方程模拟方法探讨不同组合菌种预处理对褐煤生物产气的影响。结果表明:褐煤经过菌种预处理后,生物产气量有明显的增加,最大增幅可达127%|而不同菌种两两组合按照不同顺序进行预处理后,褐煤的产气效果各不相同|通过改进的Gompertz方程进行产气拟合可知,煤样经不同组合菌种预处理后,具有更大的最大甲烷产率和累计产气潜力。研究结果为促进褐煤生物甲烷化提供了新方法。

Abstract: In order to find out the effect of different combinations of bacteria pretreatment on biomethane conversion from lignite, phanerochaete chrysosporium, pseudomonas and streptomyces viridosporus were selected to carry out biological pretreatment and biogas production experiments of lignite. The biogas production detection and Gompertz equation simulation method, the effects of different combination strains pretreatment on lignite biogas production were discussed. The results showed that the biogas production of lignite increased significantly after microbial pretreatment, with the maximum increase of 127%. According to the results of different pretreatment sequence of the same strain, the pretreatment sequence of streptomyces viridosporus + pseudomonas and pseudomonas + phanerochaete chrysosporium was better. Compared with the pretreatment results of the same strain before that of other strains, the pretreatment sequence of pseudomonas + phanerochaete chrysosporium was better than that of pseudomonas + streptomyces viridosporus. The Gompertz equation for gas production fitting, it can be seen that coal samples pretreated by different strains have greater maximum methane yield and cumulative gas production potential.
