Abstract
Key findings
- The anode-biofilm electron transfer behavior is significantly influenced by the operational mode, with a higher electron transfer rate observed in the continuous mode compared to the batch mode.
- The wastewater treatment efficiency is improved under the continuous mode, with a removal rate of 90% for COD and 85% for NH3-N.
- The biofilm thickness and microbial community structure are found to be crucial factors affecting the electron transfer behavior and wastewater treatment efficiency.
