Next, the operation of the garbage disposal based on the above configuration will be described. When performing garbage disposal, the switch 23 is turned on to activate the garbage disposal system. As a result, the electromagnetic valve 23 operates, and the garbage discarded from the sink 11 is crushed by the disposer 20 and transferred to the solid-liquid separation unit 300 by the transfer pipe 22.

Since the transfer pipe 22 is arranged to be inclined by a predetermined amount, it is possible to transfer the crushed garbage to the solid-liquid separation unit 300 without using any additional power or the like. .

When the garbage is not to be processed (for example, when flowing fresh water), the switch 23 is not turned on. In this case, the electromagnetic valve 23 does not operate, and the drainage or the like flows into the drainage pipe 12 as it is.

The crushed material transferred by the transfer pipe 22 falls on the draining plate 330 of the solid-liquid separation unit 300 and is received.

Since the draining plate 330 is formed in the shape of a pen, the turbid water of the pulverized material is dropped from the draining plate 330 and stored in the purifying tank 41 of the liquid processing unit 40 provided thereunder. The solids are transferred to the solid processing unit 50 by the rotation of the transfer plate 310, and solid-liquid separation is performed.

On the other hand, the processing tank 51 contains a carrier made of wood chips, such as sawdust, and activated carbon to which microorganisms that decompose solids and decompose the solids into carbon dioxide and water to form compost adhere. ing. The solid transferred by the transfer plate 310 and the carrier are mixed by the stirrer 52 and air is introduced into the inside.

Such a mixture of a solid and a carrier is
The heater is maintained at a predetermined temperature (30 to 40 degrees Celsius in the present embodiment) to promote the activation of microorganisms and the like.

The septic tank 41 of the liquid processing section 40 contains microorganisms (decomposing bacteria) that decompose and solidify minute solids, and the liquid stored in the septic tank 41 is supplied from the air pump 45 to the septic tank 41. By sending the air through the aeration device 42, the activity of microorganisms is enhanced to flocculate fine solids and further to scum.

The air pump 45 sucks air in the processing tank 51 from an air inlet 47 provided in the processing tank 51 and sends the air to the aeration device 52.

This is because a bad smell is generated when the solid material is composted in the processing tank 51, and if the bad smell leaks to the outside, it gives an unpleasant feeling to a user or the like. 45 prevents intake and leakage to the outside.

Since the air is blown into the turbid water in the septic tank 41, the air is deodorized by the turbid water.

The septic tank 41 is provided with a water level sensor 46 for detecting a water level. When the water level sensor 46 operates, the drain pump 44 operates to drain water.

The water to be drained is water absorbed by the plurality of hollow membranes 43. That is, at the start of drainage, the septic tank 4
The turbid water stored in No. 1 has been purified, and flocs or scum is floating in the purified water.

Since the size of the hole provided in the hollow membrane 43 is smaller than a flock or scum, the water drained through the hollow membrane 43 is purified water. With such a configuration, it is possible to reduce the turbidity of the wastewater to 300 mg / liter or less.

By the way, after the above-mentioned garbage disposal system is used, muddy water and solid matter adhere to the transfer plate 310 and the draining plate 330.

Such turbid water or the like may generate a bad smell or an insect. Therefore, the comb portion 313 of the transfer plate 310
The washing water is sprayed from to wash these.

FIGS. 5 to 7 show the structure of the transfer plate 310 in detail. FIG. 5 (a) is a top view and FIG. 5 (b) is a side view. FIG. 6 is a sectional view taken along the line AA in FIG. 5B. FIG. 7 is a view showing a water channel of the comb teeth 314.

The rotating shaft 311 of the transfer plate 310 is a tube through which washing water flows. One end of the rotating shaft 311 receives the rotating power from the electric motor 302, and the washing water is sent from the other end by a pump (not shown).

A plurality of washing tubes communicating with the rotating shaft 311 are buried in the transfer section 312, and the tips of the washing tubes protrude from the transfer section 312 to form comb teeth 314.

The comb teeth 314 are provided with a plurality of injection ports 317 for injecting cleaning water, and the injection direction is set to the plate surface direction of the transfer section 312 which is a plate-like member. This is to prevent the injected cleaning water from entering the solid processing unit 50.

Thereby, the transfer plate 310 and the draining plate 33
The turbid water and solids adhering to 0 are washed, and the washed turbid water and solids fall into a septic tank and are treated together with other turbid water.

The injection of the washing water is started when the comb teeth 314 start to enter the draining plate piece 331 and stopped immediately before the comb tooth 314 exits the draining plate piece 331.

As described above, since turbid water and solid matter adhering to the draining plate and the transfer plate can be washed and washed away, it is possible to prevent the generation of offensive odor and neglect due to their decay and the like. Further, such an operation eliminates the need for maintenance of the draining plate and the transfer plate.

When the solids are transferred to the solid processing section 50 by the transfer plate 310, the motor 361 rotates for a predetermined time to vibrate the draining plate 330. As a result, muddy water and the like adhering to the draining plate 330 are shaken down into the water storage tank.

Therefore, since the whole of the draining plate 330 and the like vibrate, there is an advantage that the leakage does not occur as in the first embodiment, and the configuration is simplified because no cleaning water is used.

The position where the vibrating body 360 is fixed and the vibration direction can be appropriately selected depending on the shape of the draining plate 330 and the like.

Further, the vibrating body 360 can be fixed to the transfer plate 310, and further, can be fixed to the holding box 350 holding the transfer plate 310 and the draining plate 330.
