Parameter optimization and mechanism of magnetic biocharenhanced microbial electrolysis cell coupling with anaerobic digestion (MEC-AD) for treatment of landfill leachate

Key Points

• Landfill leachate treatment shows enhanced efficiency using magnetic biochar with microbial electrolysis cell and anaerobic digestion.
• Parameter optimization reduces chemical oxygen demand by 65% in treated leachate compared to standard methods.
• Analysis of microbial electrolysis cell coupled with anaerobic digestion highlights the role of magnetic biochar in bioprocess enhancement.
• Supports the adoption of biochar in leachate treatment, calling for largerScale implementations to confirm these findings.
