煤系黄铁矿的生物电化学联合脱硫进展

Development on combined bioelectrochemical desulphurization of coal bearing pyrite sulfur

联合电化学因素,利用氧化亚铁硫杆菌进行煤系黄铁矿的生物脱硫,可以提高细菌活性,促使黄铁矿表面改性,强化脱硫效果。文章介绍了在电化学控制下,氧化亚铁硫杆菌的脱硫机理与影响因素,指出进一步联合生物电化学技术进行菌种驯化,研究微生物-煤炭界面作用和进行生物反应器放大将是今后的研究方向。

With the combined electrochemical factors, the oxidize ferrous sulfur bacillus can be applied to biodesulfurization of coal bearing pyrite sulfur and can improve the activity of the bacterium, promote the Modification of the pyrite surface and enhance the results of the desulfurization. The paper introduced the desulfurization mechanism and influence factors of the oxidized ferrous sulfur bacillus under the electrochemical control and the paper pointed that the combined electrochemical technology shall have a further domestication of the spawn. The research on the function of the microbe - coal interface and the enlargement of the biological reactor will be the research tendency in the near future.
