Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a garbage disposal apparatus for microbially decomposing garbage discharged from general households and restaurants.

[0002]

2. Description of the Related Art Conventional household garbage disposal apparatuses include a disposer for crushing garbage and flowing the garbage to sewage as it is with water, and a garbage incineration or drying apparatus for reducing the amount of waste.
There are substances that are mixed with sawdust and the like to reduce the amount of microorganisms by microbial decomposition.

[0003]

Of these, the disposer is the most convenient. The disposer is located at the drain of the kitchen sink, where the place where the garbage is generated and the place where it is disposed are very close and there is no need to transport the garbage. Further, since the treated material flows into the sewage, it is not necessary to pay attention to the subsequent maintenance.

[0004] Most of the other devices are installed outdoors, and sometimes emit a bad smell, and the moist garbage must be transported to the device. Also, those that are incinerated or dried emit a peculiar smell during the processing,
Very uncomfortable. Furthermore, processing residues, that is, ash and scum remain, and must be disposed of by discarding them. What degrades by mixing with sawdust also emits a characteristic odor. In addition, the device is large and requires maintenance such as replacing sawdust every few months. Thus, devices other than the disposer are extremely inconvenient.

[0005] Nevertheless, disposers are hardly popular in Japan. This is because the use of disposers can significantly reduce the quality of wastewater due to crushed garbage, putting a burden on sewage treatment plants or destroying river environments where sewage is not fully equipped. . Currently, many municipalities, especially large cities, ban the use and sale of disposers.

There is no problem if the wastewater from the disposer is treated, but this treatment has many technical difficulties. In the case of drying or incineration, in addition to the above-mentioned problems, it is necessary to dry the amount of water added at the time of pulverizing the disposer, which can be said to be a means requiring high energy. In the case of microbial treatment, in order to reduce the wastewater from the disposer to a level that does not cause environmental problems, it is necessary to increase the size of the treatment tank because the treatment takes time.

[0007] The inventors of the present invention have proposed Japanese Patent Application No. 11-151.
No. 655 proposes a garbage disposal apparatus that can use a disposer in a space-saving manner. However, this garbage disposal apparatus also has some problems, and the decomposition tanks divided into a plurality of pieces decompose microorganisms by keeping the pulverized liquid of garbage only for one day, and thus fully utilize its decomposition ability. It was a configuration that could not be said to be.

In other words, the conventional garbage disposal apparatus cannot use a convenient disposer, and even if provided with a wastewater treatment means configured to be usable, it does not sufficiently exert its decomposition ability.

An object of the present invention is to solve the above-mentioned problems, and an object of the present invention is to provide a garbage disposal apparatus which has an improved decomposability of a crushed liquid of garbage.

[0010]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention relates to a method for transferring or draining a pulverized liquid stored in a decomposing tank from each decomposing tank. Is performed. With this configuration, the pulverized liquid remaining in the decomposing tank undergoes further microbial decomposition there, so that the decomposed time is prolonged as a whole. The longer the decomposition time is, the more the decomposition proceeds, so that a garbage disposal apparatus having a high decomposition ability can be realized.

[0011]

BEST MODE FOR CARRYING OUT THE INVENTION The invention according to claim 1 of the present invention comprises a plurality of decomposition tanks for microbial decomposition of a crushed liquid obtained by mixing garbage with water and from each decomposition tank to another decomposition tank. Transfer means for transferring the pulverized liquid, drainage means for discharging the pulverized liquid to the sewage, water amount detecting means for detecting the amount of the pulverized liquid stored in each decomposition tank, and the amount of the pulverized liquid drained by the drainage means. A garbage disposal device that includes control means for controlling, and wherein the control means controls so that a part of the crushed liquid remains in the decomposition tank when transferred or drained from the decomposition tank by the transfer means or drainage means. Since the remaining pulverized liquid undergoes further microbial decomposition in the decomposition tank, the time required for decomposition is prolonged as a whole of the pulverized liquid. The longer the decomposition time is, the more the decomposition proceeds, so that a processing apparatus having a high decomposition capability can be realized.

[0012] According to a second aspect of the present invention, when the amount of the pulverized liquid in the first decomposition tank in which the pulverized liquid of garbage undergoes the first microbial decomposition is less than a predetermined amount, The setting is such that the crushed liquid is not transferred or drained from the tank, and all the crushed liquid remains in each decomposition tank, so that the microorganisms are further decomposed.

The invention according to claim 3 of the present invention is characterized in that the crushed liquid of garbage is subjected to microbial decomposition in order from the first to a plurality of decomposition tanks, and is stored in the (n + 1) th (n + 1) th decomposition tank. When the amount of the pulverized liquid that can be obtained is larger than the sum of the amounts of the pulverized liquid in the n-th decomposition tank and the (n + 1) -th decomposition tank, no transfer or drainage is performed from the (n + 1) -th decomposition tank. Since the crushed liquid in the decomposition tank is not drained again but is further decomposed by microorganisms,
The decomposition time becomes longer and the decomposition efficiency increases.

[0014] The invention according to claim 4 of the present invention is configured such that the crushed liquid of garbage is subjected to microbial decomposition in order from the first to a plurality of decomposition tanks. The amount of pulverized liquid determined by the formula: (amount of pulverized liquid) + (amount of pulverized liquid in the (n + 1) -th (n + 1) -th decomposition tank)-(amount of pulverized liquid that can be stored in the (n + 1) -th decomposition tank) Is set to be transferred or drained from the (n + 1) th decomposition tank, and (amount of the pulverized liquid in the (n + 1) th decomposition tank) −
Only the amount obtained by the above formula remains in the (n + 1) th decomposition tank, where the pulverized liquid is further decomposed by microorganisms, so that the decomposition efficiency is increased.

[0015] The invention according to claim 5 of the present invention is configured such that the crushed liquid of garbage is subjected to microbial decomposition in order from the first to a plurality of decomposition tanks, and The amount determined by the formula of (the amount of the pulverized liquid in the (n + 1) -th (n + 1) th decomposition tank) + (the amount of the pulverized liquid in the (n + 2) -th n + 2 decomposition tank) The n-th
When the amount is smaller than the amount determined by the formula +1 (the amount of the pulverized liquid that can be stored in the decomposition tank) +1 (the amount of the pulverized liquid that can be stored in the n + 2 decomposition tank), the n + 2
It is set so that no transfer or drainage is performed from the decomposition tank, and only the amount obtained by subtracting the amount obtained by the above equation from the amount of the pulverized liquid in the n + 2 decomposition tank remains in the n + 2 decomposition tank. Is further degraded by microorganisms, so that the degradation efficiency is increased.

The invention according to claim 6 of the present invention is configured such that the crushed liquid of garbage undergoes microbial decomposition in order from the first to a plurality of decomposition tanks. (Amount of pulverized liquid) + (Amount of pulverized liquid in (n + 1) -th n + 1 decomposition tank) + (Amount of pulverized liquid in (n + 2) -th n + 2 decomposition tank)-(Store in the (n + 1) -th decomposition tank) The amount of pulverized liquid determined by the formula of (amount of pulverizable liquid that can be stored in the (n + 2) -th decomposition tank) is transferred or drained from the (n + 2) -th decomposition tank. (The amount of the pulverized liquid in the (n + 2) -th decomposition tank) − (the amount obtained by the above equation) is the (n + 1) -th
The pulverized liquid remaining in the decomposition tank and, in some cases, part of the pulverized liquid in the (n + 1) -th decomposition tank is not transferred to the (n + 2) -th decomposition tank.
The decomposition efficiency is increased because each pulverized liquid remains in the +1 decomposition tank, and each pulverized liquid is further decomposed by microorganisms in each decomposition tank.

Embodiment 1 (Embodiment 1) FIG. 1 shows a first embodiment of the present invention.
And FIG. FIG. 1 is a basic configuration diagram of the processing apparatus of the present embodiment, and FIG. 2 is a flowchart showing a flow of determining a transfer amount and a drainage amount.

In FIG. 1, garbage is finely crushed together with water in a crushing section 1. The crushing unit 1 is a so-called disposer, which is composed of a motor and a hammer marker (not shown) and is directly connected to a kitchen sink drain. The pulverized liquid is transferred to the first decomposition tank 2.

The first decomposition tank 2 is a tank for decomposing organic substances in garbage by microorganisms. The inside thereof is constituted by a first filter bed 3 and a first water tank 4, and the first filter bed 3 is packed with a large number of carriers on which microorganisms (not shown) are implanted, and the microorganisms on the surface are crushed. The organic matter in the garbage is oxidatively decomposed. In the present invention, the specific method of the microbial decomposition is not limited, but for example, an activated sludge tank used for sewage treatment and the like, and a microbial membrane oxidation tank such as a rotary filter or a sprinkler filter are effective. .

Reference numeral 5 denotes a first pump, which periodically sucks up the pulverized liquid in the first water tank 4, sprinkles water on the first filter bed 3, and supplies the pulverized liquid to the first filter bed 3. The sprinkled liquid is again oxidized and decomposed by the microorganisms in the first filter bed 3 and again in the first water tank 4.
Flow down to While repeating this circulation, the pulverized liquid is gradually decomposed by oxidation.

If the disassembly process proceeds to some extent, the first switching valve 6
Operates to change the flow path, and the first water tank 4 is moved by the first pump 5.
The pulverized liquid inside is transferred to the second decomposition tank 8, where it is further decomposed by microorganisms. A first water level sensor 7 is provided in the first water tank 4, and detects the amount of the pulverized liquid. The pulverized liquid corresponding to a set amount described later is transferred by the control of the control unit 20 based on this amount.

The pulverized liquid transferred to the second decomposition tank 8 is
Microbial decomposition is performed by the second filter bed 9 in the same manner as the decomposition tank 2. Reference numeral 10 denotes a second water tank, in which a second pump 11 sucks up the pulverized liquid in the second water tank 10 and sprinkles water on the second filter bed 9. Here, if the disassembly proceeds further, the second switching valve 12 operates to change the flow path, and the second pump 11
The crushed liquid inside is drained and drained to a sewer pipe. A second water level sensor 13 is provided in the second water tank 10, and detects the amount of the pulverized liquid. The pulverized liquid corresponding to a set amount described later is drained by the control of the control unit 20 based on this amount. At this time, since the pulverized liquid has been considerably decomposed by microorganisms, the pulverized liquid has been purified to a level at which there is no environmental problem even if the pulverized liquid flows into sewage.

Next, a specific flow of the pulverizing liquid will be described with reference to a flowchart of FIG. The control unit 20 is executing this flowchart.

Now, suppose that the amounts present in the first water tank 4 and the second water tank 10 are A1 liter and A2 liter, respectively, and these amounts are the first water level sensor 7 and the second water level sensor 13 respectively.
Has been detected by It is assumed that the amount of the pulverized liquid that can be stored is 10 L in both the first water tank 4 and the second water tank 10.

Step 1 is a start, but the circulation of the pulverized liquid for microbial decomposition is in operation. In step 2, since the last garbage input at that time,
It is checked whether 20 hours, which is enough time for microbial decomposition, has elapsed. Here, if 20 hours or more have passed and the result is YES, the pulverized liquid in the first water tank 4 and the second water tank 10 is purified to a sufficient level even if they are transferred or drained to the second decomposition tank 8 and the sewage, respectively. Therefore, the transfer or drain operation is performed by the operation after step 3. The determination of the transfer amount and the drainage amount is performed by the control unit 20, and the first pump 5 and the second pump 1
1 is controlled. If the check in step 2 is NO, the transfer and drainage are not performed, and the process returns to step 1.

In step 3, it is checked whether or not A1 is 1 liter or less. If the answer is YES, the process moves to step 4. In Step 4, neither the first water tank 4 nor the second water tank 10 transfers or drains. By doing so, the pulverized liquid remaining in each of the decomposition tanks 2 and 8 is decomposed again in the decomposition tanks 2 and 8, so that the residence time is prolonged and purification is performed to a higher degree. Also,
Since more than 9 liters of new pulverized liquid can be introduced into the first water tank 4, there is enough room for new garbage to be introduced. After step 4, the process proceeds to step 0. Step 0 is a state in which fresh garbage is pulverized by the pulverizing unit 1 and the pulverized liquid is waiting to flow into the first decomposition tank 2. When the garbage has been crushed and put in, the process returns to step 1 in order to enter the operating state for decomposition.

If the check in step 3 is NO, the process proceeds to step 5. In step 5, it is checked whether the sum of A1 + A2 is less than 10 liters. YES
If so, go to Step 6 and remove the whole amount of the pulverized liquid in the first water tank 4 to the second
Transfer to water tank 10. At this time, the first water tank 10
The sum of the pulverized liquid in the water tank 4 and the second water tank 10 is contained, and since the amount is less than 10 liters, there is no overflow. After this, the water is not drained from the second water tank 10 to the sewer,
Move to step 0. By doing so, the crushed liquid of A2 liter originally in the second water tank 10 is again subjected to further microbial decomposition there, so that purification is advanced to a high degree.

If the result of step 5 is NO, control is passed to step 7. In step 7, only the amount obtained by subtracting 10 liters from the sum of A1 + A2 is drained from the second water tank 10. Then, the process proceeds to step 6, and the whole amount of the pulverized liquid is transferred from the first water tank 4 to the second water tank 10, and the process proceeds to step 0. At this time,
The second water tank 10 contains exactly 10 liters of the pulverized liquid, and the amount that was present in the second water tank before drainage is the amount obtained by subtracting A2 from 10 liters. This amount of milled liquid is not drained to the sewage, but is again degraded there again, so that the purification proceeds to a high degree.

When the above operations are carried out using a specific example, the transfer and drainage operations are as shown in Table 1 below.

[0030]

[Table 1]

(Embodiment 2) FIG. 3 shows a second embodiment of the present invention.
And FIG. FIG. 3 is a basic configuration diagram of the processing apparatus of the present embodiment, and FIG. 4 is a flowchart showing a flow of determining a transfer amount and a drainage amount. The control unit 20 is executing this flowchart.

In FIG. 3, all parts given the same reference numerals as those in FIG. 1 perform the same functions, and the description thereof is the same as that of the first embodiment, and will not be repeated.

The difference from the first embodiment is that the second decomposition tank 8
Is further provided downstream of the third decomposition tank 14. Therefore, if the decomposition of the garbage is further advanced in the second decomposition tank 8, the second switching valve 12 is operated to change the flow path, and the second pump 11 transfers the pulverization liquid in the second water tank 10. To the third decomposition tank 14.

The pulverized liquid transferred to the third decomposition tank 14 is subjected to microbial decomposition by the third filter bed 15 as in the first decomposition tank 2 and the second decomposition tank 8. 16 is a third water tank,
The pump 17 sucks up the crushed liquid in the third water tank 16 and
Water is sprayed on the filter bed 15. Here, if the disassembly proceeds further, the third switching valve 18 operates to change the flow path, and the third pump 1
7, the crushed liquid in the third water tank 16 is drained, and then flows to a sewer pipe. A third water level sensor 19 is provided in the third water tank 16,
The amount of grinding liquid is detected. The pulverized liquid corresponding to a set amount described later is drained by the control of the control unit 20 based on this amount. At this time, since the pulverized liquid has been considerably decomposed by microorganisms, the pulverized liquid has been purified to a level at which there is no environmental problem even if the pulverized liquid flows into sewage.

Alternatively, after the microorganisms are decomposed in the third decomposition tank 14, a fourth decomposition tank for further decomposing the pulverized liquid may be provided. At this time, the pulverized liquid in the third water tank 16 is not drained to the sewer pipe by the third pump 17, but is transferred to, for example, a fourth decomposition tank.

Next, a specific flow of the pulverizing liquid will be described with reference to the flowchart of FIG.

Suppose now that the first water tank 4, the second water tank 10, the third
The quantities currently in the aquarium 16 are A1 liter and A
At 2 liters and A3 liters, these amounts are detected by the first water level sensor 7, the second water level sensor 13, and the second water level sensor 19. It is assumed that the amount of the pulverized liquid that can be stored in each of the first water tank 4, the second water tank 10, and the third water tank 16 is 10L.

Step 1 is a start, but the circulation of the pulverized liquid for microbial decomposition is in operation. In step 2, since the last garbage input at that time,
It is checked whether 20 hours, which is enough time for microbial decomposition, has elapsed. Here, if 20 hours or more have passed and the determination is YES, the pulverized liquid in the first water tank 4, the second water tank 10, and the third water tank 16 is separated into the second decomposition tank 8 and the third water tank 8, respectively.
Since it is considered that the water has been purified to a sufficient level even if it is transferred or drained to the decomposition tank 14 and the sewage, the transfer or drain operation is performed by the operation after step 3. The control unit 20 determines the transfer amount and the drainage amount, and controls the first pump 5, the second pump 11, and the third pump 17. If the check in step 2 is NO, the transfer and drainage are not performed, and the process returns to step 1.

In step 3, it is checked whether A1 is 1 liter or less. If the answer is YES, the process moves to step 4. In step 4, neither the first water tank 4 nor the second water tank 10 nor the third water tank 16 drains water. By doing so, each decomposition tank 2, 8,
The pulverized liquid remaining in 14 is again decomposed in the decomposition tanks 2, 8, 14
As a result, the residence time is extended and the water is purified to a higher degree. In addition, since a new crushed liquid of 9 liters or more can be charged into the first water tank 4, there is a sufficient margin for inputting new garbage. After step 4, the process proceeds to step 0. Step 0 is a state in which fresh garbage is pulverized by the pulverizing unit 1 and the pulverized liquid is waiting to flow into the first decomposition tank 2. When the garbage has been crushed and put in, the process returns to step 1 in order to enter the operating state for decomposition.

If the check in step 3 is NO, the process proceeds to step 5. In step 5, it is checked whether the sum of A2 + A3 is less than 10 liters. YES
If so, go to step 6. Step 6 means that the water is not drained from the third water tank 16 to the sewage. By doing so, the A3 liter pulverized liquid originally in the third water tank 16 is again subjected to further microbial degradation there, so that the purification proceeds to a high degree. Thereafter, the process proceeds to step S7. In step 7, it is checked whether the sum of A1 + A2 is less than 10 liters. If YES, go to step 8 and transfer the entire amount of the pulverized liquid in the first water tank 4 to the second water tank 10. At this time, the total amount of the pulverized liquid in the first water tank 4 and the second water tank 10 enters the second water tank 10, and since the amount is less than 10 liters, no overflow occurs. after this,
The process does not transfer from the second water tank 10 to the third water tank 16, but proceeds to step 0. By doing so, the crushed liquid of A2 liter originally in the second water tank 10 is again subjected to further microbial decomposition there, so that purification is advanced to a high degree.

If the result of step 7 is NO, the process moves to step 9. In step 9, only the amount obtained by subtracting 10 liters from the sum of A1 + A2 is transferred from the second water tank 10. Then, the process proceeds to step 8, and the whole amount of the pulverized liquid is transferred from the first water tank 4 to the second water tank 10, and then proceeds to step 0. At this time,
The second water tank 10 contains exactly 10 liters of the pulverized liquid, and the amount in the second water tank 10 before drainage is the amount obtained by subtracting A2 from 10 liters. This amount of the pulverized liquid is not transferred to the next decomposition tank, but is further decomposed there again, so that purification proceeds to a high degree.

If the result of step 5 is NO, control is passed to step 10. In step 10, only the amount obtained by subtracting 10 liters from the sum of A2 + A3 is drained from the third water tank 16. At this time, the third water tank 16 contains A from 10 liters.
2 is left. This amount of milled liquid is not drained to the sewage, but is again degraded there again, so that the purification proceeds to a high degree. Then, proceed to step 7,
The transfer amount of the water tank 4 and the second water tank 10 is determined.

When the above operation is carried out using a specific example, the transfer and drainage operations are as shown in Table 2 below.

[0044]

[Table 2]

(Embodiment 3) FIG. 3 shows a third embodiment of the present invention.
This will be described with reference to FIG. FIG. 3 is a basic configuration diagram of the processing apparatus of the present embodiment, and FIG. 5 is a flowchart showing a flow of determining the amount of drainage. The control unit 20 is executing this flowchart.

The description of the basic configuration diagram of FIG. 3 is the same as that of the second embodiment, and only the flow relating to the determination of the transfer amount and the drainage amount is different. Therefore, the description of FIG. 3 is omitted.

Next, a specific flow of the pulverizing liquid will be described with reference to the flowchart of FIG.

Suppose now that the first water tank 4, the second water tank 10, the third
The quantities currently in the aquarium 16 are A1 liter and A
At 2 liters and A3 liters, these amounts are detected by the first water level sensor 7, the second water level sensor 13, and the third water level sensor 19. It is assumed that the amount of the pulverized liquid that can be stored in each of the first water tank 4, the second water tank 10, and the third water tank 16 is 10L.

Step 1 is a start, but the circulation of the pulverized liquid for microbial decomposition is in operation. In step 2, since the last garbage input at that time,
It is checked whether 20 hours, which is enough time for microbial decomposition, has elapsed. Here, if 20 hours or more have passed and the determination is YES, the pulverized liquid in the first water tank 4, the second water tank 10, and the third water tank 16 is separated into the second decomposition tank 8 and the third water tank 8, respectively.
Since it is considered that the water has been purified to a sufficient level even if it is transferred or drained to the decomposition tank 14 and the sewage, the transfer or drain operation is performed by the operation after step 3. The control unit 20 determines the transfer amount and the drainage amount, and controls the first pump 5, the second pump 11, and the third pump 17. If the check in step 2 is NO, the transfer and drainage are not performed, and the process returns to step 1.

In step 3, it is checked whether A1 is 1 liter or less. If the answer is YES, the process moves to step 4. In step 4, neither the first tank 4 nor the second tank 10 nor the third tank 16 transfers or drains water. By doing so, the pulverized liquid remaining in each decomposition tank is decomposed again in the decomposition tank, so that the residence time is prolonged and the purification is performed to a higher degree.
In addition, since a new crushed liquid of 9 liters or more can be charged into the first water tank 4, there is a sufficient margin for inputting new garbage. After step 4, the process proceeds to step 0. Step 0 is a state in which fresh garbage is pulverized by the pulverizing unit 1 and the pulverized liquid is waiting to flow into the first decomposition tank 2. When the garbage has been crushed and put in, the process returns to step 1 in order to enter the operating state for decomposition.

If the check in step 3 is NO, the process proceeds to step 5. In step 5, it is checked whether the sum of A1 + A2 + A3 is less than 20 liters.
If YES, go to step 6. Step 6 means that no water is drained from the third tank to the sewer. By doing so, the A3 liter pulverized liquid originally in the third water tank 16 is again subjected to further microbial degradation there, so that the purification proceeds to a high degree. Thereafter, the process proceeds to step S7. In step 7, it is checked whether the sum of A1 + A2 is less than 10 liters. If YES, go to step 8 and transfer the entire amount of the pulverized liquid in the first water tank 4 to the second water tank 10. At this time, the total amount of the pulverized liquid in the first water tank 4 and the second water tank 10 enters the second water tank 10, and the amount thereof is less than 10 liters and does not overflow. Thereafter, the water is not transferred from the second water tank 10 to the third water tank 16,
Move to By doing so, originally the second tank 1
A2 liters of the pulverized liquid, which was at 0, undergoes further microbial decomposition there again, so that purification proceeds to a high degree.

If the result of step 7 is NO, control is passed to step 9. In step 9, only the amount obtained by subtracting 10 liters from the sum of A1 + A2 is transferred from the second water tank 10. Then, the process proceeds to step 8, and the whole amount of the pulverized liquid is transferred from the first water tank 4 to the second water tank 10, and then proceeds to step 0. At this time,
The second water tank 10 contains exactly 10 liters of the pulverized liquid, and the amount that had been in the second water tank 10 before the transfer was 10 liters minus A2. This amount of the pulverized liquid is not transferred to the next decomposition tank, but is further decomposed there again, so that purification proceeds to a high degree.

If the result of step 5 is NO, the process proceeds to step 10. In step 10, A1 + A2 + A3
Only 20 liters is drained from the third water tank 16. At this time, the amount obtained by subtracting A1 + A2 from 20 liters remains in the third water tank 16. This amount of milled liquid is not drained to the sewage, but is again degraded there again, so that the purification proceeds to a high degree.

Thereafter, the process proceeds to step S11. Step 1
1 transfers the pulverized liquid in the second water tank 10 until the third water tank 16 becomes just 10 liters. By doing so, the third tank does not overflow and the second tank does not overflow.
In the water tank 10, the amount obtained by subtracting A1 from 10 liters remains. Since this amount of the pulverized liquid is not transferred to the third water tank 16 and the microorganism is further decomposed there again, the purification proceeds to a high degree. Thereafter, the process proceeds to step 12. In step 12, all the pulverized liquid in the first water tank 4 is transferred to the second water tank 10. Then, the process proceeds to Step 0.

When the above operations are carried out using a specific example, the transfer and drainage operations are as shown in Table 3 below.

[0056]

[Table 3]

Comparing (Table 2) and (Table 3), when the three tanks contain 8 liters of the pulverized liquid, the amount of the pulverized liquid discharged from the third water tank 16 is smaller in Example 3. The result was 2 liters less. This means that, when there are three or more decomposition tanks, the invention according to claim 6 has consideration to leave as much pulverized liquid in the decomposition tank as possible than the invention according to claim 4. As a result, further microbial degradation takes place and purification proceeds to a higher degree.

According to the second aspect of the present invention, when the amount of the pulverized liquid in the first decomposition tank in which the pulverized liquid of the garbage undergoes the first microbial decomposition is less than a predetermined amount, Since the pulverization liquid is not transferred or drained from the decomposition tank, the pulverization liquid undergoes further microbial decomposition in the remaining decomposition tank, so that a garbage disposal apparatus having a high decomposition ability can be realized.

According to the third aspect of the present invention, the garbage crushed liquid is stored in the (n + 1) -th (n + 1) -th decomposing tank, assuming that the crushed liquid of the garbage is subjected to microbial decomposition in order from the first to the plurality of decomposing tanks. When the amount of the pulverized liquid that can be obtained is larger than the total amount of the pulverized liquid in the nth decomposition tank and the (n + 1) th decomposition tank,
Since no transfer or drainage is performed from the (n + 1) -th decomposition tank, the pulverized liquid is further subjected to microbial decomposition in the remaining decomposition tank, so that a garbage disposal apparatus having a high decomposition ability can be realized.

According to the fourth aspect of the present invention,
The amount of pulverization liquid determined by the formula (amount of pulverization liquid in the n-th decomposition tank) + (amount of pulverization liquid in the (n + 1) -th decomposition tank)-(amount of pulverization liquid that can be stored in the (n + 1) -th decomposition tank) Since the liquid is transferred or drained from the (n + 1) -th decomposition tank, the pulverized liquid is further subjected to microbial decomposition in the remaining decomposition tank, so that a garbage disposal apparatus having a high decomposition ability can be realized.

According to the fifth aspect of the present invention,
The amount determined by the formula (the amount of the pulverized liquid in the n-th decomposition tank) + (the amount of the pulverized liquid in the (n + 1) -th decomposition tank) + (the amount of the pulverized liquid in the (n + 2) -th decomposition tank) is (the (n + 1) -th decomposition). When the amount is smaller than the amount determined by the formula: (amount of pulverized liquid that can be stored in the tank) + (amount of pulverized liquid that can be stored in the (n + 2) -th decomposition tank), transfer or drainage is performed from the (n + 2) -th decomposition tank. Since there is no structure, the pulverized liquid undergoes further microbial decomposition in the remaining decomposition tank, so that a garbage disposal apparatus having a high decomposition ability can be realized.

According to the invention of claim 6 of the present invention,
(Amount of pulverized liquid in nth decomposition tank) + (amount of pulverized liquid in n + 1th decomposition tank) + (amount of pulverized liquid in nth + 2 decomposition tank) −
(Amount of pulverized liquid that can be stored in the (n + 1) th decomposition tank)
(Amount of pulverized liquid that can be stored in the (n + 2) -th decomposition tank) The amount of pulverized liquid determined by the formula of (n + 2) is transferred or drained from the (n + 2) -th decomposition tank. Therefore, a garbage disposal apparatus having a high decomposition ability can be realized.
