The hydrolysis effect of waste sludge after multi-enzyme and thermophilic bacteria pretreatments is investigated using excitation-emission matrix (EEM) with fluorescence regional integration (FRI) in this study. The compositional characteristics of extracellular polymeric substances (EPS) and dissolved organic matters (DOM) were analyzed to evaluate the(More)
S-TE (solubilization by thermophilic enzyme) digestion was always used for waste sludge solubilization and reduction with the theory of lysis enzyme secreted by thermophilic bacteria. The effects of pretreated times, pH and sludge concentrations on S-TE digestion were investigated to determine the optimum S-TE conditions on hydrogen fermentation from waste(More)
Waste sludge can be solubilized after S-TE (solubilization by thermophilic enzyme) pretreatment as the cryptic growth occurs at the expense of the cell lysate. The hydrogen production from S-TE sludge is greatly influenced by many factors. In this study, factors including pH, C/N, C/P, and Fe(2+) affecting hydrogen production from S-TE sludge were optimized(More)
