Abstract
Food waste, food leachate and livestock wastes from an usual farm and a farm using much disinfectant were mixed to incubate within anaerobic serum bottle for BMP test. The methane yield rate and lag phase were determined by the modified Gompertz model and the Logistic model. The maximum methane yield rates by the modified Gompertz model were 15.9 ~ 41.0 mL CH4/g VS and higher than by the Logistic model. The modified Gompertz model was more appropriate than the Logistic model to have higher determination coefficient R2. The methane fermentation of mix with sole livestock waste from the farm using much disinfectant had ninefold lag phase and 40% or lower maximum yield rate comparing with the mix with sole usual livestock waste. The methane yield rate from a tonne of mix was increased as the ratio of food waste and food leachate increased. The cumulative methane yield was in the proportion of 40 m3 to a tonne of food wastes. The results of BMP test were analyzed by a response surface methodology (RSM) and modelized to a binomial expression, which was verified by analysis of variance (ANOVA) and to be appropriate for this case.
