In order to improve the biogas yield during anaerobic digestion of soybean protein wastewater, the effect of Fe3O4 nanoparticles (Fe3O4NPs) on methanogenesis of simulated soybean protein wastewater was investigated by batch experiment, and two models were used to analyze the cumulative methane production. The results showed that addition of Fe3O4NPs could promote the gas production, the removal rate of organic matters and the level of methanogenesis. When the mass concentration of Fe3O4NPs was 300 mg/L, the cumulative gas production reached 652.12 mL, 23.51% higher than the control. The average methane content was 81.63%, and the highest removal rates of SCOD、BOD5 and protein were 89.11%, 91.91% and 71.52%, respectively. The methane production rate reached 331.40 mL/g (SCOD). Adding Fe3O4NPs could reduce the concentration of ammonia nitrogen and total nitrogen during anaerobic digestion. Both the Transference model and the modified Gompertz model could well fit the methanogenesis process while the former fits better (R2>0.96). The maximum yield of methane was as high as 350.84 mL/g(SCOD)with 300 mg/L of Fe3O4NPs.
