Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings. FIG. 1 is a production process diagram of a fertilizer produced by a fermentation-type fertilization method according to one embodiment of the present invention. This production process is performed using a fermentation-type fertilization system 1 described later. With reference to FIG. 1, a method of converting organic waste (treatment object) into a fertilizer will be described. In FIG. 1, rectangular diagrams S1 to S10 without rounded corners indicate steps.

Here, the fermentation is a phenomenon in which the microorganism is proliferated with the decomposition of the organic matter by the microorganism, and the organic matter is converted into another different substance. This fermentation is mainly
A distinction is made between "rot" and "humus" based on whether they are harmful or useful to humans. Here, "rot" is fermentation accompanied by odor harmful to humans in the fermentation process. On the other hand, "humus" is a concept that opposes "rot" and is a fermentation that does not generate odors harmful to humans. Hereinafter, the fermentation carried out in the present embodiment involves humus of organic matter by a plurality of types of microorganisms.

The fertilizer production process shown in FIG. 1 is a process for fermenting organic waste such as raw garbage, manure of pets and livestock, pruning debris, sludge, etc. to reduce the amount of the waste and convert it into fertilizer. In the following, this embodiment will be described using quail feces as the organic waste to be turned into fertilizer.

In the fertilizer production process shown in FIG. 1, first, quail dung as a raw material is supplied to a raw material charging tank 10 (see FIG. 2).
(S1), and then a plurality of kinds of microorganisms, a plurality of kinds (multi-elements) of minerals, moisture, bran or a returning fertilizer as a moisture regulator are added (S2). These waters,
Bran and back fertilizer are added as needed.

The plurality of types of microorganisms added in the step S2 are a plurality of types of useful microorganisms (groups of useful microorganisms) useful for the growth of living organisms such as humans, animals, plants, and the like. It is composed of multiple kinds of microorganisms for guiding. The plurality of types of microorganisms include, for example, molds, yeasts, Bacillus subtilis, mesophilic actinomycetes, thermophilic actinomycetes, enterobacter, aerobic cellulose-degrading bacteria, anaerobic cellulose-degrading bacteria, ammonia-oxidizing bacteria, Nitrate oxidizing bacteria and denitrifying bacteria. As described above, the plurality of types of microorganisms include both anaerobic microorganisms and aerobic microorganisms. In addition to these plural kinds of microorganisms, enzymes such as proteases that hydrolyze proteins are added.

The plural kinds of minerals added in the step S2 are composed of minerals of multiple elements which can be ionized and dissolved in water. These minerals include, for example, silicon (Si), aluminum (Al), potassium (K), sodium (Na), iron (Fe), calcium (Ca), magnesium (M
g), titanium (Ti), manganese (Mn), sulfur (S), phosphorus (P), zinc (Zn), lead (Pb), chromium (Cr), barium (Ba), zirconium (Zr),
It is composed mainly of strontium (Sr), rubidium (Rb) and yttrium (Y).

The water conditioner added in the step S2 is a mixture of raw materials such as quail dung, plural kinds of microorganisms, plural kinds of minerals, water and a water conditioner (hereinafter, referred to as a mixture).
It is called "raw material mixture". ) Is adjusted. Here, the moisture content is
The volume ratio is expressed in percentage by dividing the volume (volume) of water contained in the raw material mixture by the volume (volume) of the whole raw material mixture.

Such a water regulator is composed of, for example, bran or a back fertilizer, and is added to the raw material mixture such that the water content of the raw material mixture is in the range of about 30% to about 70%. Things. In this embodiment, by adding the moisture adjusting agent to the raw material mixture, the water content of the raw material mixture is set in a range of approximately 55% to approximately 60%. The return fertilizer is, for example, a fertilizer produced by the fertilization method of the present embodiment, that is, the same type as the fertilized raw material mixture.

Further, quail feces, which is a raw material input in the step S1, has a high viscosity due to a small amount of fiber contained therein. Therefore, fibrous is added to the raw material mixture by adding a water regulator such as bran to quail dung, so that the viscosity of the whole raw material mixture is reduced, and the carbon content is added to the quail dung. Can be. In this way, by supplying carbon to quail dung, carbon can be given to microorganisms inhabiting bran and quail dung, and fermentation and decomposition of quail dung by such microorganisms can be promoted.

After the step S2, quail dung, microorganisms, minerals, water, bran, and return fertilizer are mixed (mixing step) (S3). At this time, the volume ratio of each component constituting the raw material mixture is such that the liquid phase (water) is approximately 60% and the solid phase is approximately 2%.
0% and the gas phase are adjusted to approximately 20%. Furthermore,
In order to ferment quail feces and produce high quality fertilizer, the ratio of carbon (C) to nitrogen (N) (CN ratio) should be 25-40.
In this embodiment, for example, approximately 25
It has been adjusted to be.

After the step S3, the primary fermentation (the former fermentation step) of the raw material mixture is performed (S4). In the primary fermentation,
While heating the raw material mixture in the closed space, the raw material mixture is stirred. In the primary fermentation, a part of the air in the closed space is circulated in the closed space. The air present in this enclosed space contains gas generated from quail feces during fermentation, for example, carbon dioxide, ammonia, etc.
By circulating this gas in the enclosed space, the atmosphere in the enclosed space can be maintained at a low oxygen concentration atmosphere. Since the activity and propagation of the anaerobic microorganisms in the raw material mixture are promoted in the atmosphere having the low oxygen concentration, fermentation of quail feces by the anaerobic microorganisms can be promoted.

After the step S4, a secondary fermentation (fermentation step) in which the raw material mixture is fermented while stirring is performed (S5).
In this secondary fermentation, stirring (stirring step) is performed by turning the raw material mixture back, while gas supply (gas supply step) for supplying gas generated from the raw material mixture to the inside of the raw material mixture is carried out in total per day. It is performed so that the air time is about 8 hours or less. Further, during the execution of the secondary fermentation, water supplementation is performed to replenish the raw material mixture with water so that the moisture content of the raw material mixture during fermentation is maintained in an appropriate range (S6).

The air present around the raw material mixture in the secondary fermentation contains, in addition to oxygen and nitrogen, gases such as carbon dioxide and ammonia generated from the raw material mixture and microorganisms suspended in the air. I have. When stirring is performed in the secondary fermentation, air around the raw material mixture is mixed into the mixture. The mixing of the air increases the volume ratio of the gas phase to the solid phase in the raw material mixture. By thus increasing the volume of the gas phase in the raw material mixture, the amount of oxygen in the raw material mixture is increased. Therefore, while the supply of air into the raw material mixture is interrupted, the oxygen concentration in the raw material mixture is increased by stirring, so that the atmosphere in the raw material mixture can be maintained at a high oxygen concentration atmosphere. In the atmosphere with the high oxygen concentration, the activity and propagation of the aerobic microorganisms in the raw material mixture are promoted, so that fermentation of quail feces by such aerobic microorganisms can be promoted. Also, by such stirring,
Since microorganisms suspended in the air can be mixed into the raw material mixture, the microorganisms can greatly promote fermentation of quail feces.

The air present around the raw material mixture in the secondary fermentation contains carbon dioxide and ammonia generated from the raw material mixture, and microorganisms floating in the air. When carbon is supplied to the raw material mixture, the atmosphere in the raw material mixture can be maintained at a low oxygen concentration atmosphere. In this low oxygen concentration atmosphere,
Since the activity and propagation of anaerobic microorganisms in the raw material mixture are promoted, fermentation of quail feces by such anaerobic microorganisms can be promoted. In addition, since the microorganisms floating in the air can be supplied to the raw material mixture by such air supply, fermentation of the raw material mixture can be further greatly promoted by the microorganisms.

The water replenishment in the step S6 is performed while adding the magnetizing active mineral and a plurality of kinds of microorganisms to the raw material mixture. Here, the magnetically active minerals are obtained by magnetizing the same kind of minerals as the plural kinds of minerals mixed in the quail feces in the step S2. In addition, this rehydration (S
The plurality of types of microorganisms added in 6) are the same type as the plurality of types of microorganisms mixed with quail feces in the step of S2.

After the step S5, a tertiary fermentation (a latter fermentation step) in which the raw material mixture is deposited and fermented is performed (S5).
7). In the tertiary fermentation, as in the case of the secondary fermentation, the raw material mixture is supplied with air and stirred. During the execution of the tertiary fermentation, water to which the magnetically active minerals and plural kinds of microorganisms are added is sprinkled on the raw material mixture,
Water rehydration is performed on the raw material mixture (S8).

In the above-described secondary fermentation (S5) and tertiary fermentation (S7), the temperature of the raw material mixture is maintained in an appropriate range for killing harmful bacteria (miscellaneous bacteria), and a plurality of types in the raw material mixture are maintained. And the action of the minerals of each other cooperate with each other, thereby suppressing the propagation of harmful bacteria in the raw material mixture. Specifically, the temperature of the raw material mixture is desirably about 30 ° C. or more and about 70 ° C. or less. By maintaining the temperature of the mixture in a range of about 60 ° C. to about 70 ° C., Harmful bacteria that are harmful to the growth of agricultural products and the like can be killed, and useful microorganisms useful for the growth of agricultural products and the like can remain.

When the tertiary fermentation (S7) is completed, post-ripening is performed in which the raw material mixture is deposited and ripened (S9). After this, air is supplied to the raw material mixture and agitated.
In post-ripening, useful microorganisms such as actinomycetes and general bacteria grow in the raw material mixture after the temperature of the raw material mixture falls below the appropriate range (for example, about 60 ° C.) in accordance with the rules of transformation and transformation of microorganisms. To start.

The quail dung aged by post-ripening (S9) is converted into a fertilizer, and the fertilizer is commercialized (S10). This productization comprises a step of pulverizing fertilizer, which is a raw material mixture after fermentation, turning it into powdered fertilizer and packing it in a shipping bag, and a step of obtaining a granular fertilizer from the raw material mixture and packing it in a bag. ing.

As described above, since the cross section of the surface of the raw material mixture is deposited on the floor 34 so as to have a plurality of arcs, the raw material mixture to be deposited is compared with a case where the raw material mixture is simply deposited in a pile. The volume of the mixture can be increased, and the heat capacity (heat storage amount) of the deposited raw material mixture can be increased. For this reason, the heat retention of the raw material mixture is improved, so that the temperature of the raw material mixture can be easily maintained in an appropriate range, for example, in a range of approximately 60 ° C. to approximately 70 ° C. Moreover, in the case where the raw material mixture is deposited as described above, the surface of the raw material mixture is flattened as compared with the case where the raw material mixture is simply deposited in a pile, so that the surface area of the surface of the raw material mixture is reduced. By reducing the temperature, the heat retention of the raw material mixture contained in the secondary fermentation tank 32 can be further improved.

Therefore, for example, even in winter, the secondary fermentation tank 3
Since the rapid decrease in the temperature of the raw material mixture deposited on the second bed 34 is suppressed, the temperature of the raw material mixture can be maintained in an appropriate range, for example, in the range of about 60 ° C. to about 70 ° C. By maintaining the temperature of the raw material mixture in an appropriate range in this way, the activity and propagation of a plurality of types of microorganisms are promoted, and thus the fermentation of the raw material quail feces can be promoted.

As shown in FIG. 2, the fertilizer making system 1
A transport switching device 54 is provided. The transport reversing machine 54
The secondary fermenter 32 is configured to be movable from the downstream end (the right side in FIG. 2) to the upstream end (the left side in FIG. 2). The raw material mixture after stirring can be transported to the downstream side of the secondary fermentation tank 32 by a predetermined distance.

Specifically, the transport turning machine 54 is configured to be able to run on a pair of rails 56, 56 installed on the pair of side walls 36, 36 in parallel with them at a position above the secondary fermentation tank 32. ing. In addition, the transport reversing machine 54

According to the transport turning machine 54, the raw material mixture scooped up by the plurality of scoops is stirred and loosened by the scoops. Thereafter, the loosened raw material mixture is dropped onto the floor 34 and deposited on the floor 34 again. Specifically, the raw material mixture accommodated in the secondary fermentation tank 32 is deposited on the lower part (lower part in FIG. 3) of the raw material mixture by the stirring, and is deposited on the upper part (upper part in FIG. 3). On the other hand, what is deposited on the upper part (the upper part in FIG. 3) is deposited on the lower part (the lower part in FIG. 3). As a result, the fermentation conditions are made uniform throughout the raw material mixture, and a plurality of types of microorganisms are uniformly dispersed in the raw material mixture.

The stirring by the transfer switching device 54 is performed by controlling the temperature of the raw material mixture within an appropriate range, that is, from about 60 ° C. to about 70 ° C.
Performed each time the temperature is raised to ° C. This stirring is repeated until the temperature of the raw material mixture does not rise to an appropriate range.

Further, the raw material mixture loosened by the agitation by the transport turning machine 54 is brought into contact with the air around the raw material mixture when falling toward the floor 34 side. For this reason,
Air around the raw material mixture is mixed into the mixture, and the mixing of the air increases the volume ratio of the gas phase to the solid phase in the raw material mixture. As described above, by increasing the volume ratio of the gas phase in the raw material mixture, the amount of oxygen in the raw material mixture is increased. Due to this increase in the amount of oxygen, while air supply into the raw material mixture is interrupted, the oxygen concentration in the raw material mixture is increased, so that fermentation by aerobic microorganisms among a plurality of microorganisms can be promoted. it can.

Microorganisms are suspended in the air present around the raw material mixture in the secondary fermentation tank 34. Therefore, when the scooped-up raw material mixture comes into contact with air when falling, microorganisms floating in the air can be deposited again while being mixed into the raw material mixture. Thus, by mixing microorganisms in the air into the raw material mixture, fermentation of the raw material can be further greatly promoted.

As described above, according to the fermentation-type fertilizer production method and fermentation-type fertilization system 1 of the present embodiment, the fertilizer produced by these methods and system 1 can be used as a mature fertilizer containing a plurality of types of minerals. It can be.
Moreover, among the quail feces as raw materials, those that can cause odors are converted into different substances without odor biochemically (bio) by the above-mentioned plural kinds of microorganisms. The generation of offensive odor can be prevented. Therefore, when the fertilizer produced in this embodiment is sprayed into a closed space such as a house, the crop can be planted on the soil immediately after the fertilizer is sprayed without waiting for the odor to disappear.

The fertilizer produced according to the present embodiment contains a large amount of various metabolites such as humic acid produced during the fermentation process by the microorganisms in the raw material mixture. Therefore, such a fertilizer has an immediate effect due to a synergistic effect with a plurality of types of minerals contained in the fertilizer, and can be used as a topdressing.

When the fertilizer produced according to the present example is sprayed on the soil, useful microorganisms in the soil are multiplied by a plurality of types of microorganisms contained in the fertilizer, and the pathogens of the infectious disease that inhabit the soil ( Since various germs are eliminated, the soil can be improved to a soil suitable for growing plants such as crops.

When the fertilizer produced in this example is applied to the soil, the useful microorganisms that have settled in the soil humify the other organic substances in the soil relatively quickly, and the soil becomes viable. . Further, when such fertilizer is applied to the soil, fumes (agglomerates) are continuously increased in the soil, and as a result, the water retention of the soil is improved and the air permeability is also improved. In other words, it can greatly contribute to soil agglomeration.

When the fertilizer produced in this example is applied to the soil and the soil is agglomerated, the heat retention of the soil is improved and the soil temperature is raised, so that the root growth of the plant becomes active. As a result, the efficiency with which plants absorb nutrients and the like from soil is increased, and the efficiency with which nitrogen, phosphorus, potassium, and silicate can act as plant fertilizers can be improved, and further, the use of chemical fertilizers is reduced. You can do it.

When the same type of crop is repeatedly harvested in the same soil, the amount of trace elements in the soil tends to be insufficient. However, if the fertilizer produced according to the present example is used in soil, the shortage of the trace elements is compensated by a plurality of minerals positively mixed in the fertilizer, so that it is possible to easily mitigate the failure of continuous cropping. it can.

[0107] The fertilizer produced according to this example has two aspects: a fertilizer aspect and a soil conditioner.
That is, from the viewpoint of fertilizer, the fertilizer according to the present embodiment has a high-quality component balance among fertilizers using a single organic substance as a raw material. In addition, from the viewpoint of the soil conditioner, the fertilizer according to the present embodiment requires that tens of millions to hundreds of millions of microorganisms per gram be added to the soil in order to supplement the useful microorganisms that have been drastically reduced by pesticides in the soil. Can be. The added microorganisms produce a large amount of metabolites in the soil, so that the soil can be improved to be more fertile.

In the fertilizer conversion system 1, the raw material mixture is agitated by the receiving and mixing section 22 before being charged into the primary fermentation tank. Fermentation conditions can be optimized.
Further, since the water content of the raw material mixture is adjusted by adding the water content adjusting agent to the raw material mixture, the water content can be easily adjusted, and the mixing of the quail feces, the water content adjusting agent, and the microorganism can be surely performed. . Moreover, the receiving and mixing unit 22
The balance between the solid phase, moisture and the gas phase in the raw material mixture, specifically, about 20% of the whole raw material mixture as a solid phase, about 60% as moisture, and about 20% as a gas phase, Fermentation conditions can be properly adjusted.

According to the fertilizer conversion system 1, since the raw material mixture is fermented by the rotary hermetic primary fermenter 23 in the initial stage of fermentation, mixing, stirring, and heating of the raw material mixture can be easily performed, and high viscosity can be obtained. The fermentation of quail dung can be performed smoothly. Also, it is possible to prevent a large amount of carbon dioxide, hydrogen sulfide, and the like generated from the raw material mixture in the initial stage of fermentation of the raw material mixture,
Thereby, the raw material mixture can be deodorized intensively. In addition, since the carbon dioxide generated on the upstream side of the primary fermenter 23 is returned to the downstream side of the primary fermenter 23, microorganisms in the raw material mixture, particularly anaerobic microorganisms, are activated by such reflux. Can be.

Further, the air (including hydrogen sulfide) refluxed as described above causes the fiber component, oil component, etc. in the raw material mixture to be removed.
Decomposition of non-aqueous chemical substances can be promoted. In addition, since a chemical change occurs between the refluxed air (including hydrogen sulfide) and the raw material mixture or a gas generated therefrom, such chemical change can promote deodorization of the raw material mixture.

The primary fermenter 23 is provided with the other tanks 3
2, 62, 64, it is not necessary to increase the installation space for the primary fermenter 23, and the installation space of the entire system 1 can be reduced accordingly. Furthermore, in the primary fermenter 23,
Since the raw material mixture charged into the next fermentation tank 24 is constantly conveyed from the upstream side to the downstream side, the raw material mixture does not accumulate in the primary fermentation tank 24 and is sanitary. Further, the raw material mixture can be continuously introduced, and quail dung can be fertilized with high efficiency.

According to the fertilizer making system 1, the raw material mixture after the primary fermentation can be fermented by the secondary fermentation tank 32 configured as described above. Since the secondary fermentation tank 32 is a deep tank type, the fermentation of the raw material mixture in the fermentation tank 32 is hardly affected by the outside air, and the fermentation conditions can be easily stabilized. In addition, since the transport switching of the raw material mixture is performed by the transport switching device 54, no manual operation is required for the transport switching and the operator is not adversely affected by the gas generated from the raw material mixture at the time of the transport switching.

Since the switching of the raw material mixture is periodically repeated, it is possible to prevent the temperature of the raw material mixture from excessively increasing during fermentation. In addition, in this embodiment, since the water is sprayed almost evenly on the whole surface of the raw material mixture, it is easy to maintain the fermentation conditions for a long time.
Further, by the water spray on the surface of the raw material mixture, a large number of aggregates constituting the surface of the raw material mixture are dissolved and bonded to each other to form a film. Therefore, it is possible to prevent the odor generated inside the raw material mixture from leaking to the outside by the film. Thus, a deodorizing effect can also be obtained.

The present invention has been described based on the embodiments. However, the present invention is not limited to the above-described embodiments, and various improvements and modifications can be made without departing from the spirit of the present invention. It can be easily inferred.

For example, in the present embodiment, the primary fermentation tank 24, the secondary fermentation tank 32, the tertiary fermentation tank 62, the post-ripening tank 64, and the bagging devices 84 and 86 as a productizing device are installed in the same site. , For example, only the primary fermentation tank 24 is placed in the vicinity of the place where quail feces are generated, while other tanks and equipment are installed on a site remote from the primary fermentation tank 24. It may be arranged in a concentrated manner. According to this embodiment, it is not necessary to prepare a large site for installing the fertilizer application system 1.

In this embodiment, the air was sucked from the primary fermentation tank 24 and supplied to the tertiary fermentation tank 62 and the post-ripening tank 64. Air may be sucked from both the fermenter 24 and the secondary fermenter 32 and supplied to the subsequent fermenter.

Further, the first to third fermentation and post-ripening of quail dung are performed in order to produce fertilizer as a product. However, if post-ripening is omitted and the overall fermentation time is shortened, Livestock feed can also be produced from the raw material mixture.

In the second fermentation tank 32 of this embodiment, the second
The gas generated from the raw material mixture was supplied from the upstream side of the fermentation tank 32 to the downstream side. However, such gas supply is not necessarily limited thereto. For example, the gas supply is performed from the downstream side of the second fermentation tank to the upstream side. The generated gas may be sent to the air.

[0119]

According to the fermentation-type fertilizer conversion method of the first aspect or the fermentation-type fertilization system of the tenth aspect,
Objects to be treated, such as manure and animal and plant residues, of livestock are mixed with a plurality of types of microorganisms suitable for growing crops and the like, and this mixture is fermented in a fermentation step or a fermenter to produce fertilizer. Therefore, by spraying the fertilized mixture on the soil, it is possible to supplement a plurality of types of microorganisms to the soil in which the number of microorganisms has been reduced by use of pesticides, etc. There is an effect that it is possible to supply to the soil a component that is a metabolite that has been grown and is suitable for growing crops and the like.

Further, since the mixture obtained by mixing the object to be treated and a plurality of kinds of microorganisms is stirred by a stirring step or a stirrer, microorganisms floating in the air can be mixed into the mixture by this stirring. . By mixing microorganisms in the air into the mixture in this way, there is an effect that fermentation of the object to be treated can be greatly promoted.

Further, air can be mixed into the mixture by stirring the mixture. This incorporation of air can increase the volumetric ratio of the gas phase to the solid phase in the mixture and, as a result, replenish oxygen in the mixture. Because of this, the oxygen concentration in the mixture is increased,
The growth of aerobic microorganisms among the plurality of microorganisms in the mixture can be activated. When the object to be treated is fermented by an aerobic microorganism in an environment where oxygen is present, the object to be treated is decomposed into water, carbon dioxide, etc. at the time of completion of the fermentation. There is.

When only fermentation by aerobic microorganisms is performed on the object to be treated, for example, a plurality of types of microorganisms that inhabit the fertilized object to be treated, particularly,
Aerobic microorganisms become vulnerable. Such fragile aerobic microorganisms have reduced resistance to anaerobic microorganisms, and further have reduced survival rates in soils with low oxygen concentrations. Therefore, even if the fertilized object to be treated is sprayed on the soil, a soil environment suitable for growing crops or the like cannot be created.

Therefore, in the fermentation step or the fermenter, gas generated during fermentation of the object to be treated, such as carbon dioxide and ammonia, is intermittently supplied into the mixture by the air supply step or the air supply device. ing. Since the oxygen concentration in the mixture is reduced by this air supply, the growth of the anaerobic microorganisms contained in the mixture can be activated, and the fermentation by the anaerobic microorganisms can be intermittently promoted.

As described above, by fermenting an object to be treated in an environment having a low oxygen concentration with an anaerobic microorganism,
The resistance of the aerobic microorganisms to the anaerobic microorganisms and the survival rate of the aerobic microorganisms in the soil with reduced oxygen content can be improved. That is, the resistance of aerobic microorganisms contained in a plurality of types of microorganisms can be improved, and the aerobic microorganisms having such resistance can be contained in a fertilized mixture. Therefore, a fertilized mixture containing aerobic microorganisms with resistance is suitable for growing crops, etc., when the anaerobic microorganisms inhabit a large number of soils or when the oxygen concentration is sprayed on low soil. There is an effect that the environment can be improved.

In an environment with a small amount of oxygen, an object to be treated is fermented by anaerobic microorganisms. In this fermentation by anaerobic microorganisms, nutrients necessary for plants growing on soil are generated, while methane,
Odorous substances such as ammonia are produced. Therefore,
In the fermentation step or fermenter, the mixture is stirred to supply oxygen to the mixture by a stirring step or a stirring device. Therefore, for example, when the air supply step or the air supply by the air supply device is interrupted, the oxygen concentration in the mixture can be increased. As described above, when the oxygen concentration in the mixture increases, fermentation by aerobic microorganisms among a plurality of types of microorganisms is promoted, and thus the aerobic microorganisms can deodorize the object to be treated. .

As described above, the balance between the number of surviving anaerobic microorganisms and the number of surviving aerobic microorganisms contained in the mixture is easily adjusted by subjecting the mixture to air supply and stirring.
