【The invention's effect】
According to the present invention , a large amount of wastewater with a small BOD and garbage and kitchen sewage can be separated at the input section, so that even in a relatively small treatment tank, organic matter overflows without being decomposed. And the size of the processing tank can be reduced. Therefore, it can be installed under the sink regardless of the installation location. And the kitchen sink where garbage etc. is generated can be treated on the spot, further eliminating the need for maintenance and disposal after the treatment, further reducing the BOD etc. of garbage and kitchen drainage, and allowing it to flow directly to the drain. In addition, it greatly improves the housekeeping work of garbage disposal, and has the effect of preventing the room from being stained by odor or juice dripping during transportation.
[0024]
In addition , at the time of garbage input, tap water can be taken into the input port by setting the lowermost position of the input port below the bottom of the sink or the upper surface of the groove at the outer peripheral portion. Further, since the inlet is usually located higher than the bottom of the sink or the upper surface of the groove on the outer periphery, wastewater not requiring treatment does not enter the inlet, and unnecessary wastewater does not enter the treatment tank. Therefore, the organic matter is less likely to overflow without being decomposed, and there is an effect that the processing tank can be reduced in size.
