Abstract
A method for enhancing anaerobic digestion based on solid-liquid interface renewal in sludge is disclosed. The method includes subjecting sludge to a centrifugation, a thermal baking and a redissolution in softened water in sequence to renew a solid-liquid interface in sludge, and subjecting the sludge to an anaerobic digestion to increase methane production from organic matter in the sludge by anaerobic biotransformation.
