Abstract
Using 125 mL serum bottle as batch reactors, the COD removal efficiency, biomass production rate, methanogenic activity and supporting shock load of anaerobic granular sludge and digestion sludge were assayed under anaerobic and microaerobic conditions. The results showed that both of the anaerobic granular sludge and digestion sludge had high COD removal efficiency, low biomass production rate, high methanogenic activity and better supporting shock load under microaerobic conditions. Moreover, the anaerobic granular sludge had apparent advantage. The optimal supplement of oxygen was 10% of the adding COD.
