文摘
- •
Microbial electrolysis cell reactor features a higher sulfate removal efficiency.
- •
Optimized applied current on MEC was 1.5 mA.
- •
Over-high current led to cell rupture and inhibition of metabolic activity.
- •
Biofilm formation could facilitate direct electron transfer rate to electrode.
- •
MEC reactor showed a higher biodiversity and SRB was dominant in the community.
