Under the condition of the same materials of 600 grams, the biogas production of the treatment with 480 grams food waste inoculated with 120 grams inoculums(TS ratio 9.47 of food waste and inoculum) was 9359 mL which was larger than that of any other treatment significantly. The reduction effects of TS, VS and CODCr were also the best, and the reduction rate was 60%, 70% and 39.67%, respectively. However, there was no significant difference in CODCr reduction compared with CK which was not inoculated.
