The crushed raw garbage that has flowed into the raw garbage dehydrator 9 is discharged from the crushed raw garbage through a large number of dehydration holes provided in the waste dehydrator 9 while being transferred by the screw conveyor 12. Then, the dehydrated crushed raw garbage is transferred to the dropping port 13 by the screw conveyor 12, and is made to flow from the dropping port 13 into the raw garbage processing tank 15 containing the filler 14 in which microorganisms are propagated. On the other hand, the water contained in the crushed food waste, which has been discharged from the dehydration hole of the waste dehydrator 9, that is, the dehydrated dirty waste water, is caused to flow into the waste water treatment tank 17 in which the filler 16 in which the microorganisms are propagated is incorporated.

The dehydrated and crushed crushed garbage that has flowed into the garbage processing tank 15 is sufficiently mixed with the filling material 14 in which microorganisms have been propagated by the stirrer 19 to enhance contact, and
Air is supplied to the microorganisms, and after decomposing and fermenting the organic substance components of the crushed food waste dehydrated by the microorganisms propagated in the filling material 14, the storage tank 2 of the food waste processing tank 15 is used as a soil improving agent.
Collect to 0.

On the other hand, the dirty wastewater that has flowed into the wastewater treatment tank 17 dissolves organic substances in a high concentration (BOD 15000 to 1).
7,000 ppm), the stirrer 19 sufficiently mixes the microorganisms propagated in the filling material 16 in the wastewater treatment tank 17 to enhance contact, and supplies air to the microorganisms to propagate the microorganisms propagated in the filling material 16. Decomposes and removes organic components to reduce contamination (BOD600pp
m or less) As waste water, it is discharged to a drain groove outside the discharge pipe 18 of the waste water treatment tank 17.

While continuing to treat the microorganisms in the food waste treatment tank 15 and the waste water treatment tank 17, the proliferation of microorganisms in the food waste treatment tank 15 and the waste water treatment tank 17 may decline. In this case, In order to replenish the microorganisms newly from the microorganism reservoir provided in the sink 1 and to maintain the activity of the microorganisms of the garbage treatment tank 15 and the wastewater treatment tank 17, both tanks may be provided with a temperature control device. .

When crushed food waste is present in the food waste dehydrator 9 and the dehydrated crushed food waste is present in the food waste treatment tank 15 by continuing the above-mentioned processing, fresh food waste is added to the disposer 3. When the disposer 3 is put in and the disposer 3 is operated, the disposer 3 is operated, the screw conveyor 12 of the food waste dehydrator 9 is operated, the agitator 19 of the food waste processing tank 15 is operated, and the agitator 19 of the waste water processing tank 17 is operated.
The operation of may be interlocked.

When the wastewater treatment tank 15 and the wastewater treatment tank 17 have been treated with microorganisms and the wastewater with a small amount of dirt simply washed with the hands or the hands is again discharged from the sink 1, the disposer 3 is used. To stop the rotation of
In conjunction with this, the electric switching valve 5 is switched to close the food waste outflow pipe 7 and open the drainage outflow pipe 6, and in conjunction with the stop of the rotation of the disposer 3, the screw conveyor 12 of the drainage pipe 11, The rotation of the stirrer 19 of the food waste treatment tank 15 and the stirrer 19 of the wastewater treatment tank 17 are stopped.

When the garbage such as food residues and vegetable scraps is again poured from the sink 1 to perform the microbial treatment in the garbage treatment tank 15 and the waste water treatment tank 17, the above-mentioned operations may be carried out, and thereafter, in sequence. This operation may be repeated.

To do.

Next, the operation of the above-mentioned sink according to the present invention will be explained. There is little stain (BOD 500 to 700 ppm) by simply washing the food or washing the hands.
When the drainage is made to flow from the sink 1, it is discharged from the drainage port of the sink 1 to the outside drainage groove via the drainage outflow pipe 6. In addition,
In this case, as described above, since the drainage outflow pipe 6 for drainage with little dirt forms a flow path separate from the flow path for food waste, the drainage outflow pipe 6 for drainage with less dirt is discharged. Even if it continues, it will not be mixed in the garbage.

When food waste such as food residues and vegetable scraps is to be discharged from the sink 1, the garbage is filled in the disposer 3 and then the disposer 3 is operated to crush the garbage, and the crushed garbage is watered. Is added to form a slurry, and the waste is discharged from the disposer 3 through the raw garbage outflow pipe 7 and the raw garbage rotating outflow pipe 11 through the outflow hole 10 of the crushed raw garbage.
Let it flow in. In addition, since the above-mentioned food waste treatment route forms a flow path separate from the drainage outflow pipe 6 of the wastewater with little dirt, even if the food waste treatment is continued, the organic matter in the food waste is highly concentrated. Dirty wastewater contained in is not discharged from the wastewater outflow pipe 6.

Dewatering and transfer of the crushed food waste that has flowed into the food waste dehydrator 9 and filling material 14 in the food waste treatment tank 15
Since the treatment of dehydrated food waste by the microorganisms that propagated the microorganisms and the treatment of the dirty wastewater by the microorganisms that propagated on the filling 16 in the wastewater treatment tank 17 are the same as in the case of the above-described Example 1, the description thereof will be omitted. .
