文摘
Fermentation of granular (GS), activated (AS) and primary (PS) sludges was compared. High lignin content in GS lowered biogas yield and rate of biogas production. Co-digestion of GS or AS with PS improved biogas yield and methane content. Theoretical biogas production of GS, AS and PS was determined.
