PROBLEM TO BE SOLVED: To enable drainage treatment without being affected by the garbage treatment capacity of a garbage treatment tank by installing a change-over means for separating drainage from a garbage grinder to one side of the garbage treatment tank and a miscellaneous waste piping. SOLUTION: A garbage grinder 2 is installed in the bottom part of a general sink 1, a connection pipe 4 on the garbage treatment tank side connecting to the tank and a connection pipe 6 on the miscellaneous waste piping side connecting to the pipe 5 are attached branchingly to the discharge opening 3 of the grinder 2. A three-way solenoid valve 7 is installed at a branch point as a change-over means. If garbage remains in the grinder 2, the valve 7 is changed over to pass drainage in the connection pipe 4 by a small amount of water so that drainage containing garbage flows from the connection pipe 4 into the garbage treatment tank. During general washing, the valve 7 is changed over to pass drainage in the connection pipe 6 so that the grinder 2 is stopped, and general kitchen drainage flows into the miscellaneous waste piping 5 from the connection pipe 6 through the grinder 2. |
