NOVELTY - Refuse mixture is transferred from storage tank (301) to separator (400) at predetermined time intervals by a controller. The separator is switched between separation mode and drying prevention mode, during which drying of solid waste remaining on it is prevented. The controller also monitors disposer operation and sets up operating frequency of separator based on liquid quantity of storage tank. DETAILED DESCRIPTION - The separated waste water is drained to water treating unit (500), connected with precipitator (530). The solid waste is transferred to solid processing unit (600). The sludge settled in the water treatment tank is returned either to the separator or storage tank. When the sludge is returned to separator, the control apparatus switches simultaneously the refuse mixture supply to the separator from the storage tank. The controller makes amount of sludge returned to separator, during solid liquid separation mode, to be larger than that returned during drying prevention mode. When the sludge is returned to storage tank, transfer of mixture is interrupted. The transfer interruption time of storage tank, during drying prevention mode is made shorter than the interruption time during separation mode. The separator is equipped with fixed board having curved type draining tooth. A transfer board moves on the fixed board, along longitudinal direction of the draining hole. The oscillating portion of the transfer board has oscillation tooth, which fixes to the draining tooth gap. The gap between oscillation tooth and draining tooth forms liquid drain line. The oscillating portion is connected to the transfer board, with predetermined curvature at which the wire striping off the solid waste, is positioned. The oscillation odontoid process of the fixed and transfer boards, makes the oscillation and draining teeth fix to each other. The fixed board is equipped with rotatable injection board, which guides the solid waste to insertion opening of solid processor. During solid separation mode, the transfer board oscillates and when feeding solid waste to processor the transfer board contacts the overhang portion of injection board through an elastic unit. The injection board is returned to its original position, by a biasing spring provided to underside of fixed board. Blowers are provided for aeration, liquid and solid transfer, sludge return, etc. The vibration-proof separator is vibrated by blower and does not transmit to other apparatus. Alternately, a convex portion is provided to transfer board which contacts with the contact rib of fixed board. The contact rib integrally supports the draining tooth on the fixed board.    USE -   For treating kitchen refuses.    ADVANTAGE -   The separator processes the waste mixture efficiently, with the help of controller. Sludge is processed efficiently, by the sludge return mechanism. The separation process, water treatment and solid processing are performed in a short time, by making the drying prevention time short. Remains of solid waste on separator are removed by the wire provided between the oscillating and fixed boards. Noise due to vibration is suppressed by the vibration-proof mechanism.
