Abstract

Abstract:

In order to further improve the electrochemical performance of microbial fuel cell (MFC), a central pulse gas-liquid-solid circulating fluidized bed microbial fuel cell reactor (CPCFB-MFC) was designed and constructed. The effects of pulse liquid flow frequency, amplitude, particle circulation rate, and gas flow rate on the power generation and sewage treatment characteristics of CPCFB-MFC were studied by designing multiple experimental conditions. Under the conditions of central liquid flow pulse frequency of 0.25 Hz, pulse amplitude of 0.08 m/s, particle circulation rate of 3.3 kg/(m²·s) and gas flow of 2 L/min, the output voltage of CPCFB-MFC reached the highest, which was 649.2 mV, and the sewage treatment time was the shortest, which was 77 h. By comparing the sewage treatment efficiency and comprehensive energy consumption under different operating conditions, it can be proven that the adoption of pulse liquid flow and gas-liquid-solid multiphase operation can further improve the comprehensive performance of MFC reactors. This work is of great significance for promoting the industrialization of microbial fuel cell technology.

摘要：

为进一步提升微生物燃料电池（MFC）的电化学性能，设计并搭建了一个中心脉冲气-液-固循环流化床微生物燃料电池（CPCFB-MFC），通过设计多组实验工况研究了脉冲液流频率和幅值、颗粒循环速率及气体流量对CPCFB-MFC产电及污水处理特性的影响。在中心液流脉冲频率为0.25 Hz、脉冲幅值为0.08 m/s、颗粒循环速率为3.3 kg/(m²·s）、气体流量为2 L/min条件下，CPCFB-MFC的输出电压达到最高(为649.2 mV），此时污水处理时间最短(为77 h）。通过对比不同工况的污水处理效率和综合能耗，证明了在反应器内采用脉冲液流和气-液-固循环运行方式能进一步提升MFC的综合性能。这项工作对推动微生物燃料电池技术的产业化具有重要意义。
