The garbage disposal apparatus 1 includes a disposer 2
A flow control tank 3, a solid-liquid separator 4, a settling tank 5,
It has a flow dividing device 6 with an ultrasonic generator, a processing column (drainage treatment device) 7, and a composting device (solid matter treatment device) 8. When such a garbage disposal apparatus 1 is applied to a house, the disposer 2 is disposed below a kitchen sink, and has a flow control tank 3, a solid-liquid separator 4, a sedimentation tank 5, an ultrasonic generator. The flow dividing device 6, the processing column 7, and the composting device 8 are housed in a main body case (not shown) and arranged outdoors.

The garbage disposal apparatus 1 performs aerobic treatment in the treatment column 7 and discharges purified water to a level that does not cause a problem for the environment to the sewer. From the composting device 8, garbage is aerobically processed and produced as fertilizer.

In the garbage disposal apparatus 1, the garbage discarded from the sink of the sink is finely pulverized by the disposer 2 to be a solid, mixed with kitchen waste water and the like, and is put into the flow control tank 3 as a solid-liquid mixture. It is thrown. Then, a solid-liquid mixture containing solid deposits settled at the bottom of the flow rate adjusting tank 3 is pumped up by the pump P and sent into the solid-liquid separation device 4. In the solid-liquid separator 4, the solid-liquid mixture is separated into a solid and a liquid (organic wastewater).

The organic waste water separated in the solid-liquid separator 4 is sent to a sedimentation tank 5 where the fine particles in the liquid are precipitated, and the supernatant organic waste water is separated by a splitter with an ultrasonic generator. 6 is sent by the pump P. In the flow dividing device 6 with the ultrasonic generator, the organic waste water is separated and sent to the processing column 7 as described later.

The treatment column 7 is provided with a filling tank filled with a microorganism carrier, the microorganism is subjected to a purification treatment of organic waste water, and the purified organic waste water is discharged to a general sewer. On the other hand, the solid separated in the solid-liquid separation device 4 is sent to the compost device 8. In this composting device 8, solids are subjected to aerobic treatment by microorganisms, and carbohydrates are converted into water and carbon dioxide, but bones and proteins contained in the solids are converted into compost containing components such as phosphorus and nitrogen. Generated.

FIG. 2A shows a flow dividing device 6 with an ultrasonic generator and a flow dividing method, which are features of the present invention.
This will be described in detail in FIG. The flow dividing device 6 with an ultrasonic washing generator has a box-shaped flow dividing tank 9 having an open top. A triangular weir 11 is formed at a front edge 10 of the flow dividing tank 9 by being cut out in a triangular shape.

In this embodiment, the weir formed at the front edge 10 of the flow dividing tank 9 is a triangular weir 11 in which the front edge 10 is partially cut off in a triangular shape. A square weir in which the edge 10 is partially cut out in a square may be used.

In this embodiment, three triangular weirs 11 are formed corresponding to the three processing columns 7. 1 corresponding to the processing column 7 to which the organic wastewater is to be flowed down
Alternatively, a configuration in which two or more triangular weirs 11 are formed at the front edge 10 of the flow dividing tank 9 may be employed.

The organic wastewater 12 that has flowed into the dividing tank 9 is
The water temporarily accumulates in the diversion tank 9, and the diversion tank 9
And flows downward through the front surface of the processing column 7. As a result, the organic wastewater sent from the sedimentation tank 5 by the pump P is buffered, and flows into the treatment column 7 little by little.

By the way, as described above, the oil in the sludge contained in the organic waste water adheres little by little to the notch edge 13 of the triangular weir 11 as shown in FIG. The flow of the weir 11 is obstructed, and if left unchecked, the triangular weir 11 will be clogged. When the flow of the triangular weir 11 is obstructed in this way, the flow is not smoothly diverted to the processing column 7, but flows off the processing column 7 to pollute the periphery.

Further, if the degree of clogging of the three triangular weirs 11 is different and the flow of each of the three triangular weirs 11 becomes non-uniform,
It becomes impossible to evenly divide the flow into the processing column 7. Therefore, it is necessary to constantly monitor the adhesion of the oil to the triangular weir 11 and scrape off the accumulated oil from the cutout edge 13 of the triangular weir.

Therefore, in the present invention, in order to prevent such oil from adhering or accumulating on the notched edge 13 of the triangular weir 11, the vicinity of the triangular weir 11, for example, FIG.
As shown in (a) and (b), an ultrasonic generator 15 is provided at a bottom portion 14 immediately below the triangular weir 11. Ultrasonic generator 1
5 is disposed in the organic drainage 12 at the bottom 14 of the flow dividing tank 9 in a watertight manner.

The ultrasonic generator 15 is configured to operate periodically at regular intervals with a timer and to apply ultrasonic waves periodically. 15 may be operated.

The operation of the flow dividing device 6 with the ultrasonic generator 15 having such a configuration and a flow dividing method will be described. The organic wastewater 12 flowing into the flow dividing tank 9 flows downward from the triangular weir 11 along the front surface of the dividing tank 9 and flows into the treatment column 7. Then, the ultrasonic generator 15 is periodically operated to periodically apply ultrasonic vibration to the triangular weir 11. In this case, the ultrasonic vibration is also applied to the organic drainage near the triangular weir 11.

By applying ultrasonic vibration to the triangular weir 11 and the organic drainage in the vicinity of the triangular weir 11, oil adhering to the surface of the cutout edge 13 of the triangular weir 11 is separated from the adhering surface of the triangular weir 11. It is peeled off, removed from the triangular weir 11, and washed away. As a result, the accumulation or clogging of oil does not occur, the organic wastewater smoothly flows down to the treatment column 7, and the uniform branch flow to the three treatment columns 7 is maintained without polluting the surroundings.

It should be noted that the ultrasonic wave generator 15 controls the flow dividing tank 9.
Ultrasonic vibration is also applied to the organic wastewater in the inside, so that solid matter (suspended matter) in the organic wastewater can be solubilized, and thereby the microbial carriers in the treatment column 7 can be clogged. This also has the side effect of maintaining smooth flow and air permeability in the treatment column 7 and performing effective aerobic treatment.

Although the embodiments of the present invention have been described with reference to the drawings based on the embodiments, the present invention is not limited to the above embodiments, but is described in the claims. It goes without saying that there are various embodiments within the scope of technical matters.

[0032]

According to the above construction of the present invention, since ultrasonic vibration is applied to the cutout edge of the triangular weir and the organic drainage in the vicinity thereof, oil adhering to the cutout edge surface of the triangular weir is removed. Separation and removal from the attachment surface prevents accumulation or clogging of the attached oil. As a result, the organic wastewater flows smoothly from the flow dividing device to the processing column and is fed to the processing column, so that the surroundings are not stained and the flow is uniformly distributed to the plurality of processing columns.

Further, according to the present invention, the ultrasonic vibration is applied to the organic wastewater in the separation tank, so that the suspended matter in the organic wastewater can be solubilized, and thereby the microorganism carrier in the treatment column can be solubilized. Clogging is prevented, smooth flow in the processing column, air permeability is maintained, and efficient aerobic processing is enabled.
