Coupled enhancement of sulfate-assisted anaerobic digestion for livestock wastewater treatment under antibiotic stress using sludge-derived biochar and zero-valent iron
{{output}}
Antibiotic stress severely inhibits anaerobic digestion performance by disrupting microbial metabolism and volatile fatty acid (VFA) conversion. To address this bottleneck, a sulfate (SO42-)-assisted anaerobic digestion system co-coupled with waste sludge-deri... ...
