Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to raw garbage generated from ordinary households and garbage generated in kitchens of restaurants in the food service industry,
In addition, after crushing the raw garbage collected in the cleaning plant etc. by the decomposition action of microorganisms, it is mixed with water to make raw garbage contaminated water, and this raw garbage contaminated water is further utilized by the decomposition action of microorganisms. Water (steam) and carbon dioxide (carbon dioxide)
The clean water obtained by completely decomposing it into water etc. relates to an apparatus for treating garbage that is to be discharged into rivers, the sea, or sewers.

[0002]

2. Description of the Related Art Conventionally, in the garbage processing equipment, the garbage is burned in an incinerator to form ash, and the ash is used as a roadbed material or is buried in a final disposal site or the like. A dry type is known in which water is removed by removing water to reduce the volume. In addition, there are a compost type that uses the action of microorganisms and decomposes raw garbage to reduce the volume and compost, and a vanishing type that completely decomposes into water and carbon dioxide.

[0003]

However, in the incineration type, in order to suppress the generation of harmful substances such as dioxins from raw garbage, it is necessary to keep the temperature in the incinerator at a high temperature all the time. In order to prevent the temperature inside the incinerator from decreasing, the incinerator must be burned for 24 hours. Therefore, the incinerator needs to have high heat resistance and must be operated for 24 hours, resulting in high equipment cost and operating cost. In addition, as the site of the final disposal site for landfilling the incinerated ash after incineration,
In addition to having to secure vast land, bad odors and dust may adversely affect the surrounding environment.

In the dry type, since the garbage containing a large amount of water is dried by evaporating the water with a heater or the like, a large amount of energy is required to completely evaporate the water, which is often a problem. Since it consumes the power of
Operating costs will be considerably higher. In addition, since it is necessary to treat the residue, it takes time and labor and there is a limit to the amount of treatment per day.

Since the compost type decomposes raw garbage by microorganisms, it requires less electric power than the above-mentioned dry type, but if a large amount of oil or salt is mixed, the decomposing ability of microorganisms is deteriorated. Therefore, it may be necessary to frequently replenish or replace the fungal bed material to which the microorganisms are attached, and it takes time to maintain the device. In addition, since it takes time to decompose microorganisms and it is necessary to treat the residue, the amount of raw garbage that can be treated per day is limited.

[0006] Then, the disappearance type, like the compost type, cannot completely decompose raw garbage, so that it is necessary to treat the residue. In addition, since it is necessary to make the device capable of introducing a microbial group (including sawdust) at a ratio of 3 to 5 times (weight) with respect to the amount of input of raw garbage, a wide installation place is required. In addition, depending on the type of food waste, it may take time to decompose, and it may not be treated even after 1 to 2 weeks.

The present invention has been made in view of the above points. It has no adverse effect on the environment and can increase the amount of raw garbage processed per day, resulting in equipment costs and operating costs ( The present invention relates to a garbage disposal device that can reduce the purchase cost of a garbage truck, labor costs, and final disposal costs.

Next, a method of treating food waste will be described with respect to an embodiment of the food waste processing apparatus having the above structure. The garbage processing device 1 is installed in a general household (a housing complex such as an apartment) or a restaurant in the restaurant industry, and the disposer 2 is placed in a kitchen or a kitchen, respectively.

Then, the raw garbage A such as the scraps after cooking and the leftover food is put into the disposer 2 and finely crushed. Then, the inside of the disposer 2 is washed with tap water or the like to discharge the crushed raw garbage A together with water from the discharge port 2a. The raw garbage A thus discharged from the discharge port 2a is sent to the storage tank 3 after being collected in the raw waste water supply pipe 51 by the raw waste water discharge pipe 50, respectively. Then, the crushed raw garbage A is blown into the storage tank 3 as raw garbage sewage B while the air containing the odor sucked by the aeration blower from the raw garbage decomposer 6 is blown from the air blowing nozzle 30. Store for a certain period.

During the storage as described above, the raw wastewater B is supplied with the settling sludge F containing the humus soil in the storage tank 3, so that the microorganisms contained in the settling sludge F are Since the solid content is finely decomposed to some extent by the decomposition action, it is possible to facilitate the treatment in the subsequent steps, prevent spoilage, and suppress the generation of odor. Further, the odor can be removed from the air containing the odor blown by the air blowing nozzle 30.

Then, the raw waste water B stored for a certain period is sucked by the raw waste water pump 21 and sent to the measuring tank 4 through the raw waste water supply pipe 52 to supply the raw waste water at a predetermined flow rate. It is charged into the screen feeder 5 through the tube 78. On the other hand, the excessively supplied raw waste water B is returned to the storage tank 3 through the drain pipe 55.

Then, with the screen feeder 5, the solid content contained in the raw waste water B is sorted into those having a diameter of 1.5 mm or more and those having a diameter of less than 1.5 mm.
The solid content having a diameter of 1.5 mm or more is discharged from the discharge port 5c, and the solid content falling below the screen 5b because the diameter is less than 1.5 mm, together with the garbage-contaminated water C filtered by the screen 5b, It is discharged from the discharge port 5d.

As described above, the water C contaminated with garbage which is discharged from the discharge port 5d and has a diameter of 1.5 mm or more and which does not contain solid matter.
Is directly sent to the biological treatment tank 9 through the drain pipe 57. On the other hand, the solid content having a diameter of 1.5 mm or more discharged from the discharge port 5d is sent to the garbage decomposing machine 6 through the solid content input pipe 56.

The conditions in the polluted water production tank 6k are adjusted so that the fermentation of microorganisms is activated, the water content (such as the amount of solid waste solids added), the temperature and the amount of oxygen. Temperature is 30-55
With the oxygen concentration maintained at 10 to 15%,
The solid content of the garbage containing water is agitated and mixed with the ceramic balls by the agitating blades 42, and is made into a powder by the decomposition action of the microorganisms attached to the ceramic balls.

Then, it is difficult to obtain with a crusher, and the solid content is less than 1.5 mm in diameter. In this way, when stirring is performed for 2 to 4 hours, a sludge state is formed due to the water content contained in the solid content.

Then, the clean water pump 28 supplies the clean water G of the disinfecting layer 11 to the sludge-like solid content through the clean water supply pipe 69 into the garbage disintegrator 6 to obtain the sludge-like solid content. Mix. At this time, the automatic valve 80 is kept closed. Then, after the clean water G is filled up to the vicinity of the drain port 6i, the clean water pump 28 is stopped and the clean water G is stopped.
Stop the supply of.

Then, by opening the automatic valve 81 and introducing the air containing the odor supplied from the aeration blower into the polluted water generation tank 6k, a state like a bubble bath is created and a fungus bed is formed. The attached sludge-like solid content is separated. Further, the sludge-like solid content is mixed with the clean water G to make the raw water polluted with water C, and the inside of the raw dust decomposer 6 is washed. At this time, the garbage-contaminated water C discharged from the drainage port 6i passes through the garbage-contaminated-water drainage pipe 60 and the garbage-contaminated-water drainage pipe 59,
It is made to flow into the reservoir 7.

When the mixing and washing are completed, the automatic valve 8
0 is opened and the raw garbage polluted water C in the polluted water generation tank 6k is made to flow into the reservoir 7 from the raw refuse polluted water drain pipe 59. At this time, all the solid content contained in the raw garbage contaminated water C passes through the screen 6e, but the ceramic balls having a diameter of 7 mm are discharged together with the raw garbage contaminated water C by the screen 6e having a diameter of 1.5 mm. It remains in the garbage decomposing chamber 6f without being discarded, and is used again to decompose the solid content of the introduced garbage.

The garbage-contaminated water C flowing into the reservoir 7 is
By injecting the settled sludge F containing microorganisms, not only spoilage is prevented, but also the function of microorganisms is utilized to decompose the solid content to some extent. At that time, air containing odor is blown from the air blowing nozzle 31 to activate the action of microorganisms to promote the decomposition action, and decompose and remove the odor contained in the air.

Thus, the garbage-contaminated water C stored in the reservoir 7 for a certain period of time is fed by the garbage-contaminated water pump 26.
It is sent to the measuring tank 8 through the raw garbage polluted water supply pipe 62. The raw garbage-contaminated water C that has overflowed when a predetermined flow rate or more is poured into the measuring tank 8 is returned to the storage tank 7 by the drain pipe 63. In this way, since the garbage-contaminated water C is always sent to the biological treatment tank 9 at a predetermined flow rate,
It becomes easy to maintain a constant concentration of, and stable treatment becomes possible.

The garbage-contaminated water C sent to the biological treatment tank 9 is
While mixing with the settled sludge F containing the humus and the activated settled sludge H, air containing odor is blown in by the air blowing nozzle 32 to activate the action of microorganisms contained therein, The solid content in the garbage-contaminated water C is decomposed. Then, the solid content of the garbage-contaminated water C is completely decomposed into water and carbon dioxide, and the nitrogen content is oxidatively decomposed. At the same time, the odor of the air blown from the air blowing nozzle 32 is decomposed and removed.

The microbial sludge D in the biological treatment tank 9 thus treated is set in the sedimentation tank 10 by the microbial sludge supply pipe 66.
To the dewatered water E and the sludge F to be solid-liquid separated by natural sedimentation. Then, the supernatant liquid of the desorbed water E, which overflows from the side wall 10d and flows into the groove 10c, is sent to the disinfection tank 11 through the treated water supply pipe 67 and sterilized, and the clean water G is discharged through the drain pipe 70 into a river or the sea. Discharge to or sewer. The settled sludge F separated and settled in the settling tank 10 is sucked up by a sludge drawing pipe 68 by a sludge drawing pump 27. At this time, air containing odor is blown into the sludge drawing pipe 68 by the distribution pipe 77, and the settled sludge F is sucked up together with the air. In this way, the sucked sediment sludge F is returned to the sedimentation tanks 3, 7 and the biological treatment tank 9 using the sludge supply pipe 74 and the sludge supply pipes 75, 76.

The settled sludge F circulated in this way is
While being circulated, the sludge supply pipe 73 sends the sludge to the sludge culture tank 12, and the air blowing nozzle 33 does not blow air containing odor, but the humus and the ore and ceramics that emit far infrared rays are loaded in the sludge incubator 40. The microorganisms contained therein are activated by being brought into contact with, for example, to obtain activated sludge H that has been activated.

Other Embodiments Next, other embodiments will be described with reference to FIGS.

Accept. Also,
Instead of the storage tank 3, the weighing tank 4, and the screen feeder 5, a feeding feeder (screw conveyor) 103 driven by an electric motor 108 is used to supply the fixed amount of raw garbage to the raw garbage decomposer 6.

To remove the odor filled in the receiving hopper 102, the other end of the intake pipe 106, one end of which is connected to the suction port 102a provided in the receiving hopper 102, is connected to the intake pipe 58. As a result, the aeration blower 20 sucks and removes together with the odor in the garbage decomposer 6.
Since the garbage disposal device 101 does not have the disinfection tank 11, the clean water supply to the garbage decomposer 6 has a water supply pipe whose one end is connected to a water supply source (not shown) such as water supply. This is performed by connecting the other end of 107 to the water supply port 6b.

It will be possible to easily install in condominiums and other condominiums and restaurants in the food service industry, and installation costs can be kept low.

Since the garbage is treated by utilizing only the decomposition action of microorganisms, dioxin and the like are not generated and the surrounding environment is not adversely affected. Besides, the clean water obtained after the treatment can be used as intermediate water.

Then, by returning the sludge containing humic substances to the storage tank or the biological treatment tank, it is possible to prevent spoilage of raw garbage wastewater and raw wastewater contaminated water, thus preventing generation of reducing bacteria. It can suppress the bad smell. For this reason,
It does not adversely affect not only the inside of the device but also the surrounding environment. In addition, the sludge used for decomposing raw garbage can be reused by circulating it while activating it in the sludge culture tank, and there is almost no need to replace the medium used for decomposition, so the cost of treating raw garbage is reduced. can do.

According to the second aspect of the present invention, raw garbage is finely crushed in advance, and after being sorted, the raw garbage is put into the raw garbage decomposing machine, whereby microorganisms can be decomposed quickly and an extra treatment step can be omitted. As a result, more efficient processing can be performed. Therefore, the processing time can be further shortened,
The amount of raw garbage processed per day can be significantly increased. Therefore, it is possible to consolidate a plurality of garbage disposal sites.

The invention according to claim 3 further comprises garbage.
By selecting so that it can be easily treated with microorganisms, it is possible to reduce the number of extra treatment steps,
Since the decomposition by microorganisms will be carried out promptly, the processing time can be greatly shortened.
The throughput per day can be further improved. In addition, since the processing time can be considerably shortened, various expenses such as electricity costs for the processing can be reduced.

According to the invention of claim 4, since the structure is relatively simple, the installation cost is low, and the repair work and the maintenance work can be easily performed. Therefore, the maintenance cost can be kept low. it can.

In the invention according to claim 5, the sludge used for decomposing raw garbage can be repeatedly circulated and used while being activated. Therefore, it is not necessary to add a medium for decomposing raw garbage. It is possible to reduce the maintenance cost. Moreover, since the degrading action of the microorganisms can be regained, it is possible to prevent the processing time from being prolonged due to insufficient decomposition of the garbage.

According to the sixth aspect of the present invention, by activating the action of the microorganisms adhering to the fungal bed material in the garbage disintegrator, it is possible to accelerate the decomposition action of the garbage using the microorganisms. Therefore, it is possible to decompose the garbage in a short time, and it is possible to greatly improve the processing capacity per day.
