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.
