There has been an indication that physicochemical pre-treatment may not be efficient to the anaerobic digestion of sewage sludge. Therefore, an innovative configuration incorporating physicochemical treatment as an inter-stage mode, were proposed and evaluated in this study. Based on a batch study, heat treatment of 120℃ and 30 min. was employed as the physicochemical treatment. The 77 days continuous experiment verified that, compared with basic two-stage digestion and pre-treatment configurations, the inter-stage treatment configuration can enhance anaerobic digestion of sewage sludge with respect to solids destruction. The disadvantage is the reduced SRT inevitably resulting from the configuration.
