Anaerobic fermentation by aquatic product wastes and other auxiliary materials

The efficiency of the biogas production from aquatic product wastes was researched through the proportioning materials of nine part organic waste to one part rice straws, peanut hull powder or food wastes, respectively. Such four treatments were analyzed to see their respective impacts on gas production of anaerobic fermentation. And then the biogas slurry of each treatment was used for inhibiting experiment on Fusarium oxysporum f.sp.niveum (FON). The final result indicated that organic wastes mixed with food wastes guaranteed quality and quantity of biogas production. The unsterilized biogas slurry displayed strong inhibiting effect on FON growth by 78.17 %. The daily largest biogas production was 3,870 mL/day on the 25th day, the total biogas production 38,230 mL and TS biogas production rate 692.42 mL/g, respectively, in Group D from fish waste and food waste.
