Abstract
Disclosed is an on-site treatment method of food waste generated from multi-unit dwellings and institutional food service facilities, by transporting wastewater-containing food waste to a separation chamber by use of domestic wastewater or an additional transporter; separating the transported food waste to wastewater and food waste; and treating the separated wastewater in a sewage disposal plant, and the separated food waste using disposal equipment. Such food waste can be treated even using disposal equipment of small capacities, due to separation of wastewater and food waste, compared to disposal equipment of large capacities required for treating wastewater and food waste together. Also, the quality of the separated wastewater is better than the conventional quality of wastewater, and thus loads of the sewage disposal plant can be efficiently decreased.
