Key Points

The aim is to investigate how the carbon to nitrogen (C/N) ratio affects nitrogen transformation pathways and microbial dynamics in constructed wetland-microbial fuel cell systems.
Analyzed the influence of varying C/N ratios on pollutant removal and energy generation.
Conducted microbial community analysis to observe shifts in dynamics.
Constructed a correlation model to evaluate the relationships within the system.
Examined synergistic mechanisms for optimizing performance.
Higher C/N ratios improved pollutant removal efficiency.
Power generation showed significant increases correlating with optimal C/N ratios.
Microbial community shifts aligned with changes in C/N ratios, indicating functional adaptations.
