To optimize the operation parameters of a food waste biogas plant, the physico-chemical properties of food waste,leachate, and their hydrolysis characteristics, and rate were investigated by a survey and experiments. Food waste analysis during thesurvey revealed a pH of 4.92, TS of 16.25%, VS of 13.9%, TCODCr of 145,100 mg/L, SCODCr of 58,600 mg/L, T-N of 4,665 mg/L,T-P of 823 mg/L on average. Leachate analysis revealed a pH of 4.40, TS of 6.83%, VS of 6.17%, TCODCr of 80.635 mg/L, SCODCrof 40,700 mg/L, T-N of 3,747 mg/L, and T-P of 389 mg/L on average. The rate constants, k1 and k2, of hydrolysis with a mixture of theabove mentioned food waste and leachate were determined by hydrolysis experiments at different temperatures with different TSconcentrations. As a result, the optimal reaction time was determined to be less than 2 days and the maximum hydrolysis rate wasshown to be 32 to 64%. This data is very useful for improving the operation and basic design of biogas plants using food waste andleachate as feed.
Abstract
To optimize the operation parameters of a food waste biogas plant, the physico-chemical properties of food waste,leachate, and their hydrolysis characteristics, and rate were investigated by a survey and experiments. Food waste analysis during thesurvey revealed a pH of 4.92, TS of 16.25%, VS of 13.9%, TCODCr of 145,100 mg/L, SCODCr of 58,600 mg/L, T-N of 4,665 mg/L,T-P of 823 mg/L on average. Leachate analysis revealed a pH of 4.40, TS of 6.83%, VS of 6.17%, TCODCr of 80.635 mg/L, SCODCrof 40,700 mg/L, T-N of 3,747 mg/L, and T-P of 389 mg/L on average.
