Abstract

Leachate is a complex wastewater with high organic and nutrient content that poses a significant risk of environmental pollution if not properly treated. One of the promising approaches is the Constructed Wetland–Microbial Fuel Cell (CW-MFC) system, which integrates plant and microbial biological processes with electrode utilization to simultaneously treat pollutants and generate electricity. This study employed Typha latifolia with zinc (Zn) electrodes and aeration treatments to evaluate the effectiveness of the system in reducing pollutants and producing bioelectricity. The observed parameters included COD, Total Nitrogen (TN), as well as voltage, current, and power output. The results showed that zinc electrodes achieved COD removal efficiency up to 95% and TN removal up to 88% at the optimal retention time, although a decline was observed on day 16 due to microbial saturation and root exudate release. Statistical analysis revealed that the type of electrode had a significant effect on voltage generation (p-value = 0.006), while aeration and retention time did not show significant effects on electricity production. In conclusion, the CW-MFC system with zinc electrodes and Typha latifolia has great potential as an alternative technology for leachate treatment while simultaneously generating environmentally friendly electricity.
