Abstract

(57) [Summary] [Structure] The disposer 2 is attached to the drainage port of the sink, and the object to be treated from the disposer 2 is fixed outdoors by the solid-liquid separation section 6 having a draining plate 5 for separating it into liquid and solid. After liquid separation, the liquid content of the object to be treated is stored in the septic tank 4 provided below the draining plate 5 and aerated by the aeration device 11, and the solid content is rotated by the transfer plate 8 provided in the solid-liquid separation unit 6. A sensor 10 that detects the scum generated on the surface of the water in the septic tank 4 due to aeration is disposed near the bottom of the draining plate 5 as well as being decomposed by microorganisms etc. transferred to the processing tank 19 and cultured in the carrier 18. By doing so, when the scum floats on the draining plate 5, the transfer plate 8 is rotated to transfer the scum to the processing tank 19 for processing. [Effect] Since the object to be treated such as garbage can be separated into liquid and solid and decomposed respectively, and the scum of the septic tank can be decomposed together with the solid, it is possible to prevent the reduction of the purification efficiency due to the generation of scum.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a food waste treatment system that separates food waste into solids and liquids to treat liquids and solids.

[0002]

2. Description of the Related Art Conventionally, for example, a solid-liquid separation unit for separating solid and liquid of crushed material crushed by the disposer is provided on the downstream side of the disposer disposed in a kitchen sink. It is known that the solid separated by the separation unit is stored in a bag and the liquid is discarded without being purified. (Publication No. 58-9639 (B02C 18/4
2) etc. However, since such wastewater has a large value of BOD, COD, etc., when it is directly discharged into the sewage, there is a problem of causing environmental pollution.

Further, since the solid content is stored in a bag or the like, there are problems such as generation of bad odors and insects, and there is a drawback that the user feels uncomfortable.

In view of these problems, in recent years, a purifying device for treating waste water, a treating device for decomposing raw garbage, and the like have been commercialized. As described above, the crushed material crushed by the disposer is solid-liquid separated. After that, it is possible to treat them with a purifying device and a garbage treatment device, respectively.

However, there is a problem that scum is generated by aeration during purification of waste water, and the scum reduces the purification efficiency. Therefore, a method of removing the scum floating on the surface of the drainage has been proposed, but it is difficult to treat the removed scum.

When the disposer 2 is driven to throw in garbage, the garbage crushed by the disposer 2 is guided to the solid-liquid separation section 6 through the transfer pipe 3, and the crushed material is drained by the draining plate 5. Moisture (liquid) is dropped from the slit 7 and stored in the septic tank 4, and solids are transferred by the transfer plate 8 to the processing tank.
Transferred to 19.

At this time, since the slit 7 of the draining plate 5 of the solid-liquid separating section 6 is formed in the direction orthogonal to the rotation axis of the transfer plate 8, the object to be treated such as kitchen waste dropped on the draining plate 5 Is easily moved by the rotation of the transfer plate 8 and is unlikely to be clogged.

The liquid stored in the septic tank 4 is aerated by the action of the air sent through the aeration device 11 connected to the pump 12, and is periodically connected to the septic tank 4 by the control of the solenoid valve 15. It is drained from the drain pipe 14.

Then, the water level in the septic tank 4 rises or
When the amount of scum increases and reaches the position detected by the sensor 10, the scum on the surface of the liquid floats on the draining plate 5, so that the signal of the sensor 10 drives the electric motor 9 to rotate the transfer plate 8. Thus, the scum floating on the draining plate 5 can be transferred to the processing tank 19 and the scum on the liquid surface can be removed.

When the water level in the septic tank 19 rises and the sensor 10 detects water, the solenoid valve 15 is opened and the drain pipe 14 is opened.
The water level in the septic tank 4 is prevented from rising above a predetermined level.

On the other hand, in the processing tank 19 into which the solids are charged, the solids transferred from the solid-liquid separation unit 6 are supported by the stirring body 20.
While being mixed with 18, the inside of the processing tank 19 is maintained at a predetermined temperature by a heater provided on the outer surface of the processing tank 19, and the carrier 18
Solids are decomposed into carbon dioxide and water by the microorganisms cultivated in the above and composted.

With the above structure, organic matter such as kitchen waste generated in the kitchen is separated into a solid and a liquid by the solid-liquid separation section 6, and the liquid is purified by aeration in the septic tank 4 and discharged, and the solid is removed. It can be composted in the processing tank 19.

The scum generated by the aeration process of the liquid floats on the draining plate 5 of the solid-liquid separation unit 6 when the liquid in the septic tank 4 reaches a predetermined water level, and therefore is transferred by the signal of the sensor 10. When the plate 8 rotates, the scum generated on the surface of the liquid is transferred to the processing tank 19 by the transfer plate 8 and decomposed in the processing tank 19 in the same manner as the solid, and the scum is removed to improve the purification efficiency of the wastewater. The decrease can be prevented.

According to the first aspect of the present invention, the material crushed by the disposer is separated into water and solid by the solid-liquid separation unit, and the liquid is dropped and stored in the septic tank and decomposed by aeration treatment. In addition to being processed, the solid content can be transferred to the processing tank by the transfer means and decomposed, so that an object to be processed such as kitchen waste can be efficiently processed.

According to the second aspect of the present invention, the object crushed by the disposer is separated into water and solid by the solid-liquid separation unit, and the liquid is dropped and stored in the septic tank to be decomposed by aeration. At the same time, since the solid content can be transferred to the processing tank by the transfer means and decomposed, the object to be processed such as kitchen waste can be efficiently processed.

Further, scum generated by aerating the water in the septic tank can be transferred to the processing tank by driving the transfer means in response to the signal of the detecting means and removed, thereby improving the efficiency of wastewater decomposition processing. It can prevent the deterioration.
