Abstract

Compared with a microbial fuel cell (MFC) of single flora, the MFC of mixed flora provide much better denitrification and electricity generation performance. Therefore, in-depth analysis of the kinetic features such as the structures of various types of microflora in MFCs is of important theoretical and practical significance. There is little existing research on the electricity generation and pollutant removal process of cathode microorganisms and the functions of microbial flora. To this end, this paper constructs an MFC anaerobic-aerobic coupled denitrification system and studies its performance enhancement method. First, the basic principle of MFC biological denitrification was expounded, the kinetics was introduced into the analysis of the reaction between the MFC microorganisms and pollutants, and the migration and transformation occurring in the reaction process and the mechanism of transformation speed changes were revealed. Then, the analysis and calculation methods for the electrochemical parameters and microbial diversity index in MFC were explained in detail, and the experimental results and analysis conclusions were given.

MFC厌氧-好氧耦合反硝化系统的构建及其性能提升方法

与单一菌群的微生物燃料电池（MFC）相比，混合菌群的MFC提供了更好的脱氮和发电性能。因此，深入分析MFC中各种类型微生物群落的结构等动力学特征具有重要的理论和实践意义。关于阴极微生物的发电和污染物去除过程以及微生物菌群的功能，现有的研究很少。为此，本文构建了MFC厌氧-好氧耦合反硝化系统，并对其性能提高方法进行了研究。首先，阐述了MFC生物脱氮的基本原理，将动力学引入MFC微生物与污染物的反应分析，揭示了反应过程中发生的迁移和转化以及转化速度变化的机理。然后，详细阐述了MFC中电化学参数和微生物多样性指数的分析计算方法，给出了实验结果和分析结论。
