摘要

采用人工湿地-微生物燃料电池技术(CW-MFC)深度处理养猪废水,评估了污染物去除效果、产电性能及微生物群落结构.结果表明,种植旱伞草的实验装置(PCW-MFC)对NH₄⁺-N、TP、磺胺嘧啶(SDZ)的平均去除率分别提升约5%、10%和3%,输出电压、库仑效率和最大功率密度分别达到415.93mV、49.10%和51.12mW/m³.旱伞草增加了变形菌门、拟杆菌门、厚壁菌门等的相对丰度,这些微生物在污染物去除和生物产电中发挥了关键作用.

Abstract

In this study, swine wastewater was treated using constructed wetland-microbial fuel cell (CW-MFC) technology. The pollutant removal efficiency, bioelectricity generation and microbial community structure were evaluated. The results showed that after treated the swine wastewater by the experimental system planted with umbrella grass (PCW-MFC), the average removal efficiencies of NH₄⁺-N, TP and sulfadiazine (SDZ) were increased by approximately 5%, 10%, and 3% respectively, and the output voltage, coulombic efficiency, and maximum power density were recorded as 415.93mV, 49.10%, and 51.12mW/m³, respectively. The relative abundances of Proteobacteria, Bacteroidetes and Firmicutes were increased by umbrella grass, which played a key role in pollutant removal and bioelectricity generation.
