A novel model for the kitchen garbage treatment, “crushing with disposer, anaerobic-aerobic degradation in digester, sewerage discharge”, was evaluated in this study. The solubilization and degradation of crushed kitchen garbage were observed in anaerobic wastewater treatment at various temperatures (35°C, 25°C and 13°C) with different addition of nutrients. Both effluents and mass balances of anaerobic-aerobic kitchen garbage treatment were examined at various temperatures with nutrients being added. Experimental results and total cost analysis indicate that the kitchen garbage reduction, the operational safety and economy concerned with the proposed model are optimized at 25°C.
