Hydrolysis and methane yield enhancement of anaerobic co-digestion of kitchen waste and dewatered sludge by air/carbon dioxide nanobubble water and their hybrid
Anaerobic co-digestion of kitchen waste (KW) and dewatered sludge (DS) has attracted considerable attention, but the accumulation of volatile fatty acid (VFA) and hazardous substances can affect biogas yield and hinder its application.
