خلاصه مقاله:
Abstract The bio-hydrogen and bio-methane productions from paper mill effluent (PME) were done via dark fermentation and anaerobic digestion, respectively. The experiments were performed using Heat-shock pre-treated anaerobic sludge under mesophilic conditions. The impact of substrate concentration (5, 10 and 15 g-COD/L) and the initial pH of the system (5 and 7) on the efficiency of dark hydrogen fermentation from PME were investigated, and the optimum hydrogen yield of 55.4 mL/g-COD was obtained at substrate concentration and pH of 5 and 5, respectively. After the definition of the optimum substrate concentration and initial pH, three substrate hydrolysis including acidic, acidic-thermal and alkaline hydrolysis were done which the alkaline hydrolysis led to the maximum hydrogen yield of 62.2 mL/g-COD. Moreover, the highest methane yield of 569 mL/g-COD was obtained at substrate concentration and pH of 5 and 7, respectively.
