Abstract：In order to clarify whether the multi-component mixture of municipal solid waste may have an impact on its methane production performance, effects of inoculum sources on the anaerobic degradation of single and multi-component materials were studied by conducting biochemical methane potential (BMP) experiments on food waste (FW), newspaper (NP) and branch (BR) at mesophilic temperature (37±1)℃. The modified Gompertz model was used to fit and analyze the kinetic characteristics of the methanogenesis process, and a quantitative index method was developed to evaluate the impact on co-degradation performance. The results of experiments and model fitting exercises showed that the inoculum source had no significant effect on the biodegradability of single and multi-component materials, but had significant effect on its degradation rate. In addition, although the mixing of the components promoted the rate of degradation at the initial stage of the test, only the tri-component mixture test group showed a significant synergistic promotion in the final cumulative methane yield, and the methane yield increased by 16% and 14%, respectively, compared with the mono- degradation of materials with two different inocula.
