A refuse/oil removing device and a refuse/oil recovery bag are provided which can remove refuse and oil contained in drainage discharged from a restaurant in a simple manner without contact with the refuse and oil. A support base of a support unit is disposed in the interior of a grease trap at a position higher than the water level. A recovery bag is attached to the support unit and plural layers of bag portions of the recovery bag are put on the support base. The bag portions are each formed of a material which permits the adhesion of oil thereto and a large number of water passing holes are formed in each of the bag portions. Drainage is introduced inside the innermost one of the plural layers of bag portions and is passed through the bag portions, allowing refuse and oil to adhere to the bag portions. In this way, the job of replacing the recovery bag can be simplified and the amount of oil accumulated within the grease trap can be decreased.
