Abstract

Abstract: In this study, anaerobic fermentation continuous system was carried out for hydrogen production by low concentration of beverage manufacture process wastewater, the most of the food industry wastewaters are in a relative low sugar concentration. The used substrate concentration of cultivation was 10 g total sugar/L, and hydraulic retention time (HRT) was 1 h for cultivation. Then the substrate concentration of experiments was lowered to 5 g total sugar/L, and HRT 1 h after the cultivation was completed. As a result, hydrogen production rate (HPR) was 11.39 ± 1.39 L/L/d, and yield was 0.30 ± 0.06 mol H2 /mol hexose at HRT 1 h. The results showed that the hydrogen dark fermentation production in a continuous system is feasible at low concentrations for food industry wastewater. The sustainable biohydrogen production technology not only treat wastewater but also generate electricity from hydrogen via PEMFC. The SO 3 2 − on biohydrogen production, increased with increasing of sulfate concentration can inhibit microbial growth at excess concentration. Sulfate-reducing bacteria (SRB) will cause hydrogen gas converting hydrogen sulfide become poor hydrogen production efficiency. Highlights: BHP by beverage manufacturing process wastewater has been demonstrated. Sulfate concentration has a negative effect on biohydrogen production. Low substrate concentration of food processing wastewater can produce BHP stable.
