Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to an organic waste treatment device that centrally processes waste from disposers installed in each unit of an apartment complex.

Conventional Structure and Problems In the treatment of organic waste in general households, a method is used in which wet materials are placed in a treatment bag and stored and treated until the collection date. However, the current situation is that wastes in storage are particularly troubled by rotting and bad odors, especially in the summer. Disposers have been commercialized as a method to treat this, but their use is prohibited due to problems with their ability to treat public sewage.

Therefore, the problem of disposing of organic waste remains unresolved, and this problem has become a particularly big issue in apartment complexes.

Purpose of the Invention The present invention is an organic waste treatment system that improves the comfort of living in an apartment complex by pulverizing the organic waste discharged from households in an apartment complex, collecting it, and discharging it into sewage. It provides equipment.

Structure of the Invention The organic waste treatment apparatus for an apartment complex of the present invention includes a disposer installed in each unit, and a filter that separates solid and liquid of the waste collected by the piping system that collects the waste crushed by the disposer. ,
This system includes an anaerobic fermentation tank for treating solid matter separated by a filter and an aerobic treatment tank for treating liquid, and the aerobic treatment tank is connected to the filter section to use odor for aeration. The waste (hereinafter referred to as food waste) is then decomposed into fermentation gas and water in the anaerobic fermentation tank, and the waste liquid is overflowed into the aerobic treatment tank, where it can be discharged into sewage.

DESCRIPTION OF EMBODIMENTS An embodiment of the apparatus of the present invention will be described below with reference to the drawings. The disposers 1, 2, and 3 are each attached to the kitchen sink of each household, and as the number of households increases, the number of disposers will naturally increase to three or more.

The garbage crushed by the disposers 1 to 3 passes through the S-shaped portions 4, 5, and 6 together with water, and is collected by the piping system 7 to reach the confluence point 7a.

The piping after this confluence point 7a opens into a filter 8, such as a drum type, and all the crushed food waste flows therein. The filter 8 performs solid-liquid separation, and the solid matter 9 is charged into the anaerobic fermentation tank 10 through the input port 15. A stirrer 16 and the like are installed in the anaerobic fermentation tank 10, and a pipe 11 for use of fermentation gas is provided on the ceiling, which is connected to combustion equipment. Further, an overflow pipe 12 is provided to take out the overflow liquid, and the overflow flow is guided to the adjustment tank 21 via a pipe 19. Adjustment tank 21
has a pump 23 and guides overflow water to a first settling tank 24 through piping 22. Here, floating components settle out,
A portion is returned to the anaerobic fermentation tank 10 via the pipe 13 by the pump 25 to ferment undigested matter, and the other portion is discharged from the handling section 29 as sludge.

The supernatant liquid waste from the first settling tank 24 flows into the aeration tank 26 . Here, the blower 28 filters the filter 8,
The odor near the input part 15 of the anaerobic fermentation tank 10 is sucked in by the suction pipe 36, and aeration is carried out by the aeration part 27 at the bottom of the aeration tank to oxidize the waste liquid. This waste liquid flows into the second settling tank 30 to settle floating matter, and the sludge is returned to the adjustment tank 21 by the pump 31 via the piping 20. The treated water that has been subjected to sedimentation treatment in the second sedimentation tank 30 overflows into the treated water tank 32. This treated water is pumped to pump 3.
4 is discharged from a discharge pipe 35 to a sewer or the like, but a part of the water is sent to the spray nozzle portion 17 of the filter 8 via a pipe 18 by a pump 33, and is used as washing water for the filter 8. This washing water and the liquid separated by the filter 8 are both flowed into the adjustment tank 21 through the pipes 14 and 19 for water treatment. The above-mentioned adjustment tank 21, first settling tank 24, aeration tank 26, second settling tank 30 and treatment tank 32 are connected to each other,
This constitutes an aerobic treatment tank.

It is assumed that the aerated air is discharged into the atmosphere through the odor port 37.

This treatment device is usually installed in the basement (ground level) 38 of an apartment complex.

As mentioned earlier, the current situation is that food waste from general households is collected individually and left to public disposal, but the above-mentioned example device does not require a processing device to be installed in each household. Only a disposer is attached to each house, and pulverized waste is collected from all the houses to undergo anaerobic fermentation, while at the same time the waste liquid is treated aerobically. Therefore, garbage can be disposed of without any effort. Furthermore, by collecting food waste from each household and performing fermentation, there is less unevenness in both quality and quantity of input materials, and stable fermentation gas can be obtained and used. Furthermore, the anaerobic fermentation tank 10 and the aerobic treatment tank require maintenance, and since they can be installed in one place, maintenance work becomes easy.

Furthermore, the waste collected from each house is separated into solid and liquid by a filter 8 and sent to an anaerobic fermentation tank 10 and an aerobic treatment tank, so each tank is functionally divided and compact. Additionally, the entire system is extremely rational, as it is designed to utilize odor aeration, use treated water for washing, and reuse sludge.

Effects of the Invention As described above, the device of the present invention uses a streamlined system to hygienically dispose of food waste discharged from each unit of an apartment complex without bothering housewives, thereby streamlining and comforting people's lives. This increases the In particular, since the odor generated from the filter section is led to the aerobic treatment tank and used for aeration, the generation of odor can be effectively suppressed.
