2. Description of the Related Art A variety of complex organic substances produced on the earth are fermented and decomposed by ancient microorganisms to fertilize soil and fertilize rivers, lakes and oceans, and create new organisms such as plants and animals. It has been a source of generation and has repeatedly created and reduced such organic substances, creating and developing nature on earth. In recent years, however, human society classifies organic matter into valuable materials that can be used as food and wood, and waste materials such as livestock excrement, plant residues, livestock residues, food residues, and food waste, and the former valuable materials. On the other hand, they were treated carefully, but the latter waste was simply discarded as an unnecessary substance for human society. As a result of discarding a large amount of harmful wastes for many years, it has been a cause of pollution that destroys the natural environment on the earth, reduces the fertility of farmland, and pollutes rivers, lakes and marine areas. Therefore, not only industry, but also agriculture and livestock industry are required to improve their constitution to environmental conservation type.

Therefore, in recent years, organic substances, which have been regarded as wastes in various fields in recent years, are rendered harmless by fermentation treatment of microorganisms, composted to be used as organic fertilizers on farmland and soil, and used as feed for livestock. As a result, the technology for reuse has been actively developed. However, the conventional composting technology has developed microorganisms and fungi for rapidly fermenting and decomposing organic matter, developing combinations of microorganisms and fungi suitable for decomposing organic matter, and promoting fermentation. The main purpose of the research was to develop a fermentation facility that can adjust the fermentation conditions such as temperature and air for the fermentation.

However, in the method of fermenting an organic substance having various components and complicated as described above only by the activity of microorganisms such as fungi, it takes a certain amount of time to complete maturation and a foul odor is generated in the fermentation process. Inevitable,
Frequently, complaints were raised from neighboring communities as an environmental problem.

That is, the first technical problem concerning the environmental problem that occurs when the organic matter is fermented by the microorganism is that the period required for the fermentative treatment is too long. When trying to ferment organic matter by the decomposition activity of microorganisms such as fungi, human beings can only add strong fungi or prepare environmental conditions in which those microorganisms are easy to act, and to what extent fermented in a predetermined time Whether it decomposes depends on the action of the microorganism. Therefore, even if the organic raw material and the fermenting fungi are put in the fermenter and the air and temperature conditions are adjusted to the optimum ones, the primary fermentation takes 10 to 12 days, and the secondary fermentation takes 7 to 14 days.
It usually takes about a day. That is, it usually takes about 20 to 25 days at the earliest to decompose the organic matter raw material into the aged organic fertilizer. Therefore, the research target in various fields is how to ferment organic matter in a shorter period than that.

The second of the above technical problems is that when a fermentation method using a microorganism is adopted and the fermentation is anaerobic fermentation, a strong malodor is generated, and even if the fermentation is aerobic fermentation, fermentation starts. It is not possible to prevent the generation of malodor during the period from the transition to complete aerobic fermentation. Therefore, how to collect, deodorize or deodorize the malodor generated in the decomposition treatment process of the organic material raw material is an important technical issue from the viewpoint of environmental protection.

[0007] Therefore, the present inventors not only let the decomposition treatment of various and complicated organic substances be the fermentation treatment by microorganisms, but by using it in combination with the decomposition treatment by enzymes,
We decided to work diligently based on the idea and policy to make it possible to simultaneously achieve the two major goals of improving efficiency in a shorter period of time and suppressing the odor in the decomposition process as much as possible. .

The method of the short-term decomposition processing, which is the first goal, is
It was decided to establish a technology that realizes short-term decomposition of organic substances by combining enzymatic decomposition processing and fermentation processing by microorganisms and by the synergistic effect of both.

The second goal is to prevent and control odor.
Rather than a method of recovering the bad odor after deodorization and deodorizing or deodorizing the bad odor, study the main component of the bad odor, and neutralize, adsorb, or dissolve the main component by pretreatment,
We decided to develop a method that does not generate odor as much as possible.

[0010] When the prior art was investigated with respect to the above idea, it was found that inventions using an enzyme to improve the decomposability of agricultural waste or food waste or to promote the fermentability were as Patents 2655960 and 2920259. Confirmed to exist.

The former Japanese Patent No. 2655960 discloses that the agglomerate of fibrous solid organic waste is mixed with a fibrinolytic enzyme which is a mixture of cellulase and hemicellulase in the presence of water and hydrolyzed, and then aerobic. A method for composting a fibrous solid organic waste, which is characterized in that fermentation is performed. The gist of the prior invention resides in that the fibrous solid organic waste is hydrolyzed by a fibrinolytic enzyme as a pretreatment and then aerobically fermented. However, raw garbage, manure, sludge, livestock residue, which is the raw material of compost,
Organic wastes such as plant residues usually contain not only fibrous solid organic matter but also complex and various components such as starch, protein and fat, which is a characteristic. It is practically almost impossible to sort out only fibrous solid organic matter from such a general waste by component. Therefore, just by adding a fiber-degrading enzyme as in the prior art, it is not possible to efficiently decompose organic wastes and organic substances of various components, and it is not always possible to promote fermentation.

In the latter patent 2920259, the immature compost in which anaerobic bacteria, aerobic bacteria and active nodule bacteria are mixed is mixed with a contaminant mainly composed of organic fiber and a small amount of fermentation enzyme is added. And fermented at 30 to 70 ° C. and then dried to obtain a compost material fermentation accelerator. The technology is that immature compost containing various microorganisms and a mixture consisting mainly of organic fiber are mixed, and a small amount of fermentation enzyme is added to ferment to make a fully-ripened organic fertilizer, and that it is dried. There are features. In the invention, when a composting material fermentation accelerator is produced, a fermentation enzyme is added to ferment, but if the fermentation starts and the temperature rises, the enzyme will immediately expire, so its action is until the initial fermentation. So practically little effect can be expected. Moreover, this technique uses fermented organic fertilizer as a fermenting seed material, and it is the same idea as a method of producing compost from the old days, in which the completed fertilized compost is returned and added to the compost element material as compost to promote fermentation. . Its characteristics are the effect of actively bringing in useful microorganisms into the compost material, the effect of preventing the generation of hydrogen sulfide and underground toxic gases, and the prevention of phosphoric acid immobilization by using fully-ripened organic fertilizers in which useful microorganisms are secured. The effect is to exert a fixed bacteria-proliferating effect of nitrogen. Furthermore, by drying the fully-ripened organic fertilizer, it is convenient for storage and management. That is, the present invention is a method of drying and stabilizing an aged organic fertilizer, and by activating the organic fertilizer by adding it to an organic material, if necessary, to start the fermentation of the organic material by microorganisms and accelerate the fermentation. is there. However, the prior invention concerned produces enzymes by itself, produces nutrients preferred by microorganisms,
There is no idea of collecting various microorganisms, no idea of suppressing the odor generated by the compost material by means other than aerobic fermentation, and no idea of enzymatically decomposing the organic material that is input later. Therefore, although it is possible to ferment organic materials,
It is impossible to achieve the object of the present invention in which the compost material is decomposed in an odorless state in a shorter period of time than before.

Next, the inventors have found that plant residues discharged from agriculture, seafood residues discharged from the fishery industry, livestock excrement discharged from the livestock industry, food residues discharged from food factories, restaurants, households, etc. We researched the main components of malodor generated from organic waste containing various and complex components such as slaughterhouses, livestock residues discharged from slaughterhouses, sludge discharged from sewage treatment plants, etc. As a result, it was found that the main components of the malodor generated by these organic wastes are roughly classified into the following four types. 1) Nitrogen-containing compounds such as ammonia and methylamine. 2) Sulfide-containing substances such as hydrogen sulfide and methyl mercaptan. 3) Aldehydes such as acetaldehyde and propionaldehyde. 4) Fatty acids such as butyric acid and valeric acid.

[0014] In order to recover and deodorize all of the various malodors emitted from these organic raw materials after they have been volatilized and diffused in the air, a large-scale device and high technical skill are required. The cost for that is enormous. Therefore, in the present invention, it was decided to develop a method for chemically and biologically eliminating the main component of the malodor based on the idea that "the odor needs to be removed from the source".

[0015]

DISCLOSURE OF THE INVENTION Some of the inventors of the present invention produce a large amount of a fermentation enzyme capable of expressing an enzymatic activity by contacting an organic matter in which complicated and diverse components are mixed in advance. And the production of the nutrient source preferred by the microorganisms occur in conjunction with each other, maintaining a large content due to the continuous production action of these fermentation enzymes and nutrient sources, and synergistically amplifying the fermentation promoting effect. We have succeeded in developing a fermentative decomposition promoting material for organic substances that can be used. As a result of analyzing and examining such a material for promoting the fermentation decomposition of organic matter, it was found that the material has the following characteristics to exert the action and effect.

First of all, since the material for promoting fermentation and decomposition of organic matter contains a large amount of fermenting enzyme, if this material is mixed with the organic matter, the enzyme acts as a pretreatment and one of the constituent components of the organic matter is Part or all of them have a property of being decomposed in a short time, and of producing a nutrient source, which assists and accelerates the subsequent fermentation and decomposition action by microorganisms.

Secondly, since the material for accelerating the fermentation and decomposition of the organic matter is an acidic solution due to the produced lactic acid and other organic acids, the alkaline odors of ammonia, amines and the like are neutralized and adsorbed for a moment. In addition to deodorizing, it is a fermenting enzyme solution containing soluble water and alcohol, so it has the property of dissolving and deodorizing odors of sulfides and odors of aldehydes and fatty acids. is there. The fermentation decomposition accelerating material having such characteristics can rapidly and continuously eliminate the main component of the organic matter which gives off a bad odor.

Thirdly, the fermentation decomposition promoting material for organic matter decomposes organic matter in which complicated and diverse components are mixed by fermentation enzymes, and self-digests one after another to generate nutrient sources preferred by microorganisms. Therefore, it is capable of activating the growth and activity of microorganisms and synergistically amplifying the fermentation promoting effect.

Therefore, if the material for promoting the fermentation and decomposition of the organic substance is utilized so that the above-mentioned properties possessed by the material can be well expressed, the raw material of the organic substance is decomposed to be harmless and composted. We were able to obtain the technical knowledge that it could be efficiently realized in a short period of time while preventing the bad smell of.

On the basis of the above technical knowledge, the present invention performs a process of decomposing and aging various and complicated organic substances in a shortest possible time period, and a bad odor in the decomposition process. (EN) It is intended to provide a method for producing an environmentally friendly organic substance in a compost, which can simultaneously and efficiently realize what is done while preventing and suppressing the above.

[0021]

[Means for Solving the Problems] The first invention to be granted a patent is to ferment an organic fermentation base material containing water, an enzyme and a microorganism to produce an acidic solution containing alcohol, lactic acid bacteria or an organic acid as the enzyme. Fermentative decomposition promoting material characterized by having been produced, or an adaptive type fermentative decomposition having an organic material raw material decomposing activity by mixing and fermenting the organic material raw material or its squeezed juice into the fermentation decomposition promoting material Prepare promotional materials. Then, the organic material raw material as it is, or if necessary, after pretreatment such as shredding, crushing, crushing, liquid squeezing, solution solidification, and the like, the fermentation decomposition accelerating material or the fermentation decomposition accelerating material of the organic matter And, if necessary, auxiliary materials for adjustment are added to form a composite organic material raw material. At the same time, the entire composite organic material raw material is adjusted to a water content of about 50 to 70%. Then, this composite organic material raw material is placed in a stirring and mixing type enzyme reaction tank and stirred while adjusting the temperature at 35 to 45 ° C. to mix and prepare so that the composite organic material raw material is almost uniform, and then mixed and prepared almost uniformly. The composite organic material raw material thus prepared is laid down and sufficiently enzymatically decomposed. Then, the enzymatically-decomposed composite organic material raw material is put into a fermenter, and a fermentation process is performed while blowing air so that the material is in an aged state.

In the first aspect of the present invention, a material for complex organic matter is prepared by using the material for promoting fermentation and decomposition or the material for promoting fermentation and decomposition of organic matter. The mixture is stirred and mixed until it becomes uniform while adjusting the temperature at 30 to 45 ° C., whereby the enzyme is surely brought into contact with the entire complex organic material raw material and the enzyme is activated, thereby efficiently and sufficiently Perform disassembly processing. After that, hot air is blown in to activate the microorganisms, and thereby the fermentation treatment is efficiently performed. In this way, a method of producing organic matter in compost in which the enzymatic decomposition treatment and the fermentation treatment are carried out stepwise, and the synergistic effect of both treatment methods prevents and suppresses the malodor and allows the organic matter to mature in a shorter period of time. Was realized.

The most important point in the present invention is that the enzyme is brought into contact with the whole of the composite organic material raw material almost uniformly, and that the enzyme which is sensitive to high temperature is activated and sufficient enzyme decomposition treatment can be carried out. Is to build. Specifically, a) adjusting the temperature of the composite organic material raw material placed in the stirring and mixing type enzyme reaction tank to 30 to 45 ° C. to prevent the enzyme from being activated and deactivated; b) stirring well to perform organic fermentation. The base material, water, enzymes, microorganisms, and nutrients are uniformly mixed so that the entire organic fermentation base material is uniformly enzymatically decomposed. C) The microorganisms and the enzyme are mixed by uniformly stirring and mixing the complex organic matter. Disperse water and prevent local microbial fermentation, and prevent inadvertent inactivation of the enzyme due to the heat generated by the enzyme decomposition treatment, d) Organic material fermentation decomposition promoting material Or, the compatible fermentative decomposition promoting material is an acidic solution containing alcohol, lactic acid bacteria and organic acid in the enzyme, so when this is mixed into the complex organic material raw material, the main components such as ammonia and amines that give off a foul odor Not only does it neutralize and adsorb the alkaline odor of the product and instantly deodorize it, but it is also a fermenting enzyme solution that contains soluble water and alcohol, so the odor of sulfides and aldehydes and fatty acids It also dissolves odors and deodorizes it. E) Enzymes work well and the organic fermentation substrate decomposes enzymatically to decompose some starch into glucose and some proteins into amino acids. This is because it serves as a component so that the fermentation in the next stage can proceed rapidly.

As described above, according to the present invention, the enzymatic decomposition treatment and the fermentation treatment are combined with each other, and the simple decomposition of both treatment methods such as temperature adjustment and stirring and mixing is performed, and the synergistic effect is produced by the designed operation. It will be an epoch-making one that simultaneously solves the difficult technical problems of preventing and controlling odors.

The second invention to be patented is characterized in that an organic fermentation base material is fermented by containing water, an enzyme and a microorganism to produce an acidic solution containing alcohol, lactic acid bacteria or organic acid in the enzyme. Fermentation and decomposition promoting material for organic substances, or rice bran or rice and rice with water that has been heat treated, mixed with water containing koji and mineral components, and then autodigested mainly with the enzyme of koji to obtain an enzyme digestion solution. , The yeast was added thereto and fermented to produce an acidic solution containing alcohol, lactic acid bacteria or an organic acid in the enzyme digestion solution, a material for promoting the fermentation decomposition of organic matter, or rice bran or wheat 7 ± 5% And 60 ± 10% of water was heated to about 70 to 80 ° C to 55 to 60 ° C and mixed with 21 ± 9% of koji and 7 ± 5% of mineral spring-containing mineral water and / or mineral water. And mainly of koji The enzyme digestion solution that was saccharified and produced by autolyzing it for 1 to 3 hours at 55-60 ℃ was cooled to room temperature below 30 ℃ and yeast 0.2-0.5% was added to this enzyme digestion solution. 1 to 30-35 ° C
Fermentation and decomposition promoting material for organic matter, characterized by fermenting for 3 days to obtain an acidic solution containing produced alcohol, lactic acid bacteria and organic acid at a pH of about 4.0 ± 0.5, or fermentation of the organic matter In the decomposition promoting material, squeeze of organic material raw material is mixed, and a fermentative decomposition decomposition promoting material having an organic material raw material decomposition activity obtained by fermentation decomposition, or
A compatible fermentative decomposition promoting material having a plant organic matter decomposing activity obtained by mixing an organic matter mainly composed of a vegetable protein into the organic matter fermentative decomposition promoting material and fermenting and decomposing it, or the plant organic matter Any of the compatible fermentative decomposition decomposition promoting material with the fermentative decomposition activity of the animal organic material obtained by mixing the organic matter mainly composed of animal protein into the compatible fermentative decomposition decomposition promoting material having the decomposition activity Be prepared.

Then, the organic raw material is used as it is, or if necessary, subjected to pretreatment such as shredding, crushing, crushing, liquid compression, solution solidification, and the like, and then the organic material is subjected to fermentation decomposition promoting material or adaptive fermentation. Decomposition promoting materials are added, and if necessary, supplementary materials such as rice bran, fumigation and other nutrient assisting materials such as moisturizing compost and water conditioner are added to form a composite organic material raw material, and the total amount of the composite organic material raw material is 50 to 50%. Adjust the water content to about 70%. Then, this composite organic material raw material was put into a stirring and mixing type enzyme reaction tank, and stirred for 1 to 3 hours while adjusting the temperature to 30 to 45 ° C. to mix and prepare the composite organic material raw material so as to be uniform. Then, the uniformly mixed and prepared composite organic material raw material is aged for about 20 to 48 hours for enzymatic decomposition while adjusting the temperature to 30 to 45 ° C. Thereafter, the enzyme-decomposed complex organic material raw material was further put into a fermenter, and the fermentation treatment was performed while blowing air into the fermenter, and the mixture was heated to 60 to 80 ° C. and aged in about 10 days. Is a method for producing an organic substance into compost.

The second invention is basically the same as the first invention, but is characterized in that the fermentation decomposition promoting material for organic matter or the adaptive fermentation decomposition promoting material is prepared in various modes. That is, the production of the composite organic material raw material and the adjustment of the water content, the mixed preparation of the composite organic material raw material, the enzymatic decomposition treatment, and the fermentation treatment are more specifically numerically limited. The present invention is a method for producing an organic matter into compost by earlier decomposition treatment than conventional ones by a synergistic effect of combining enzymatic decomposition treatment and fermentation treatment.

The fermentation decomposition promoting material which is the basis of the fermentation decomposition promoting material for organic matter or the adaptive fermentation decomposition promoting material is
It is a liquid material that is produced by self-digesting rice malt in the first stage to make an enzymatic digestion solution and fermenting yeast in the second stage to produce an acidic solution containing alcohol, lactic acid bacteria and organic acids.

First, the enzyme digestion liquid produced by the autolysis of koji in the first stage will be described. Koji mold has a strong ability to decompose proteins, starches and lipids of beans and cereals for a long time, and miso,
It is known to make brewed foods such as soy sauce and sake. That is, koji mold is capable of producing many kinds of enzymes such as various amylases that decompose starch, various proteases that decompose proteins, lipases that decompose lipids, and cellulases that decompose fibers among microorganisms. Therefore, rather than administering a single enzyme, many enzymes can be produced and used inexpensively only by using koji. Garbage and organic waste, which are composted and used as raw materials for organic fertilizer, contain many components such as starch, protein, fat, and fiber. It will be suitable for fermentation.

In addition, in the enzyme digestion solution in which the koji added as a raw material is self-digested by various enzymes produced by itself, the dextrin obtained by decomposing the starch in the koji by the enzyme α-amylase produced by koji mold, In addition, it includes those decomposed into glucose by the enzymes β-amylase and glucoamylase. Furthermore, the protein in koji is decomposed into peptides by the enzyme proteinase,
In addition, those in which peptides and amino acids are produced by the enzyme peptidase are included. These are the action of enzymes to decompose macromolecules such as starch and proteins, and at the same time, the degradation products serve as nutrient sources for yeast, lactic acid bacteria, and acetic acid bacteria that work later, and promote the growth and activation of these microorganisms. . Furthermore, the minerals and vitamins and nucleic acids in rice bran added as raw materials, and the minerals in mineral water added as raw materials also serve as nutrient sources (growth factors) that promote the growth and activation of microorganisms, resulting in the fermentative decomposition of organic matter. Promotes action. As described above, the enzyme digestion solution contains a large amount of glucose, dextrin, peptides and amino acids produced by itself, and also contains a large amount of vitamins, nucleic acids and minerals added as raw materials.

Next, as a subsequent treatment, yeast is added to the enzyme digestion solution prepared in the previous treatment to ferment it. Then, the yeast mainly decomposes glucose into alcohol and carbon dioxide by fermentation by microorganisms, and lactic acid bacteria contained in the fermentation and lactic acid bacteria contained in rice bran produce lactic acid from glucose. Furthermore, other organic acids are also produced by bacteria that are likewise contaminated during fermentation. The fermented enzyme solution becomes an acidic solution having a pH of about 4.0 ± 0.5 due to the organic acids such as lactic acid and the thus produced. The fermenting enzyme solution of this acidic solution has the property of instantly deodorizing alkaline odors such as ammonia and amines emitted from organic wastes and manure.

As described above, the materials for promoting the fermentation and decomposition of organic substances according to the present invention include various amylases produced by Aspergillus oryzae,
Many types of enzymes such as various proteases, lipases and cellulases, various nutrients (growth factors) such as glucose, peptides and amino acids produced by these enzymatic decompositions, and vitamins, nucleic acids and minerals added as raw materials Alcohol, carbon dioxide, acetic acid, lactic acid, and other organic acids that are decomposed and produced by nutrient components (growth factors) and fermentation by microorganisms, and lactic acid bacteria, acetic acid bacteria, koji mold, and other fermentations that act during fermentation decomposition It is a liquid material that contains a large amount of various microorganisms such as bacteria.

Therefore, the material for promoting the fermentation and decomposition of organic substances according to the present invention includes the decomposition action of various organic substances by these various enzymes, various nutrient components (growth factors), and fermentation by lactic acid bacteria and yeast. By the parallel double fermentation action, elements that accelerate the decomposition and fermentation of organic matter are generated one after another,
It is a material that works together to promote fermentation and decomposition without producing a foul odor in a short period of time. Its characteristic is that it is a necessary fermentation enzyme (amylase, protease, lipase, cellulase) capable of expressing an enzymatic activity by causing a contact action with both organic waste and organic matter in which complicated and diverse components are mixed. Etc.) in a large amount, and also in a large amount of glucose and dextrin produced by enzymatic decomposition. In addition, the minerals and vitamins and nucleic acids in rice bran, minerals in mineral water, etc. Factor).

That is, simply by mixing the fermentation decomposition promoting material with organic matter such as waste, which is a diverse and complicated component,
The malodor of the organic substance is neutralized and eliminated, and first the enzyme decomposes the organic substance. In addition, the microorganisms are propagated in the decomposed organic matter, and the microorganisms are further proliferated and activated by a nutrient source generated by autolysis so that the microorganisms can be rapidly and strongly fermented and decomposed.

It should be noted that the rice bran was first heat-treated because rice bran has many nutrients favored by microorganisms such as vitamins so that various bacteria can easily propagate. Therefore, the rice bran can be spoiled by being carelessly killed by growing at low or medium temperature. , So as not to interfere with the autodigestive action of koji. In addition, mineral water and mineral water are added because the enzyme skeleton component and the mineral component that serves as a growth factor for the microorganism are contained, so that the addition of these nutrient sources activates the microorganism to facilitate fermentation. .

Therefore, according to the present invention, when the above fermentation decomposition promoting material is mixed with the organic material raw material, firstly, glucose or amino acid decomposed from starch or protein, vitamin of rice bran or lactic acid obtained by decomposition thereof Nutrient sources such as lactic acid, acetic acid, citric acid, minerals of mineral water help fermentation decomposition by microorganisms, and secondly, cell walls of organic matter are partially destroyed by fermentation enzymes, aerobic bacteria, Aspergillus,
Since conditions such as actinomycetes, filamentous fungi and other microorganisms are easily fermented, the activity of the microorganisms is promoted, complete fermentation decomposition is completed in a shorter period than before, and odor is suppressed in a shorter period than before. It is possible to produce aged organic fertilizer.

Since there are various kinds of organic raw materials, it is often necessary to physically pretreat them for efficient and stable decomposition and fermentation. Preferably, the solid is a viscous solid substance having an appropriate water content in the form of powder, granules, flakes, or flakes. It may be left as it is depending on the type of raw material,
If necessary, pretreatment such as shredding, crushing, crushing, liquid squeezing, and solution solidification may be performed. For example, in the case of large items that are often found in agricultural products, it is necessary to shred them first,
When the water content is 90% or more, which is often the case with raw dust, it is subjected to liquid compression and solid-liquid separation, and the solid part is made a part of the organic material raw material, and the liquid (juice) part is It is mixed with the fermentation decomposition promoting material and used as a part of it. Such pretreatment is for uniformly and efficiently contacting or acting with an enzyme or a microorganism.

A third invention to be patented is characterized in that an organic fermentation base material is mixed with water, an enzyme and a microorganism and fermented to produce an acidic solution containing alcohol, lactic acid bacterium or organic acid in the enzyme. Prepare a fermentation decomposition promoting material for organic matter, or a compatible fermentation decomposition promoting material having organic material raw material decomposition activity obtained by mixing organic material raw material or its squeezed juice into the fermentation decomposition promoting material for fermentation decomposition deep. Then, by mixing the organic material raw material with the organic material raw material fermentation decomposition promoting material or the adaptive fermentation decomposition promoting material while deodorizing and suppressing the bad odor emitted from the organic material raw material, enzymatic decomposition processing and fermentation processing are performed to reach an aged state. It is a method for producing organic matter in compost by a method of preventing malodor, which is characterized in that

[0039] The third invention also has basically the same effect as that of the first invention, but is characterized in that enzymatic decomposition is carried out by using the material for promoting the fermentation decomposition decomposition or the material for promoting the fermentation decomposition of an adaptable material. It is processed and fermented so as to be in an aged state, but the point is that the malodor generated by the organic material raw material at that time is deodorized and suppressed. In particular, it is characterized in that the bad odor is not generated by simply mixing the fermentation decomposition promoting material into the organic material raw material, instead of removing the generated bad odor with an apparatus.

The fourth invention to be granted a patent is characterized in that an organic fermentation base material is fermented by adding water, an enzyme and a microorganism to produce an acidic solution containing alcohol, lactic acid bacteria or organic acid in the enzyme. Prepare a fermentation decomposition promoting material for organic matter, or a compatible fermentation decomposition promoting material having organic material raw material decomposition activity obtained by mixing organic material raw material or its squeezed juice into the fermentation decomposition promoting material for fermentation decomposition deep. Then, by adding the fermentation decomposition promoting material or the compatible fermentation decomposition promoting material to the organic material raw material to form a composite organic material raw material, the deodorization / suppression of the malodor possessed by the fermentation decomposition promoting material or the compatible fermentation decomposition promoting material is carried out. Stir-mix type enzyme reaction accelerator tank for complex organic material raw material that expresses characteristics to deodorize and suppress the offensive odor emitted by organic material raw materials, and subsequently deodorizes and suppresses the malodor emitted by organic material raw materials By mixing and stirring while adjusting the temperature to 45 ° C. or lower, the composite organic material raw materials are mixed and prepared to be substantially uniform,
Fermentative decomposition promoting material or compatible fermentative decomposition promoting material has a deodorizing / suppressing characteristic expression environment for malodor, and further enhances the deodorizing / suppressing effect of malodor emitted from organic raw materials After the complex organic matter raw material was laid down and enzymatically decomposed while maintaining the deodorant / suppressed state of the malodor, the enzymatically decomposed complex organic matter raw material was put into a fermenter to maintain the deodorant / suppressed state of the malodor. It is a method of producing organic matter in compost by a malodor preventing method, which is characterized by performing fermentation treatment while blowing air as it is to attain an aged state.

The fourth aspect of the invention is also characterized in that the fermentation decomposition promoting material for organic matter or the adaptive fermentation decomposition promoting material is used to carry out enzymatic decomposition treatment and fermentation treatment so as to reach a mature state. , At that time, the temperature is adjusted to 30 to 45 ° C. so that the enzyme is not activated and does not become ineffective, and the enzyme is uniformly mixed to prepare the enzyme so that the enzyme is uniformly contacted and the enzyme decomposing action is sufficiently performed. The deodorization / suppression of the malodor generated by the organic material raw material is performed by adjusting the environment so that the deodorization / suppression property of the malodor possessed by the fermentation decomposition promotion material or the compatible fermentation decomposition promotion material is exhibited. It is the same as the third aspect of the present invention in that the malodor is not generated by only mixing the fermentation decomposition promoting material into the organic material raw material, instead of removing the malodor generated by the device. The deodorizing mechanism when the target organic substance is decomposed and fermented using the fermentation decomposition promoting material according to the present invention will be described below.

The main components of offensive odors emitted from livestock manure and garbage are roughly classified into nitrogen-containing compounds such as ammonia and methylamine, sulfide-containing compounds such as hydrogen sulfide and methyl mercaptan,
There are four types of aldehydes such as acetaldehyde and propionaldehyde, and fatty acids such as butyric acid and valeric acid.

The most abundant of these malodors is ammonia, which is a nitrogen-containing compound. The fermented enzyme solution is acidified by lactic acid and the like, and weakly alkaline ammonia is adsorbed to the acid solution and neutralized to eliminate the odor. Further, if fermentation is continued under aerobic conditions, the odor disappears as the nitrate transforms to nitrate. The amines are adsorbed to the acidic enzyme solution and become odorless in a similar manner.

Hydrogen sulfide, which is a sulfide-containing substance, is first dissolved by the fermentation enzyme solution. Since the fermented enzyme solution contains a component having a dissolving power such as alcohol, it is considered that the fermented enzyme solution is adsorbed to the fermented enzyme solution during stirring. When it is adsorbed and dissolved, the odor is almost gone. Then, under aerobic conditions, it is gradually oxidized to sulfate by sulfur bacteria.

Aldehydes and fatty acids are both compounds having an aldehyde and a carboxyl group at the end of a straight chain hydrocarbon. These residues have an affinity for water and the hydrocarbon moieties have an affinity for alcohols. The fermentation enzyme solution containing these water and alcohol easily dissolves aldehydes and fatty acids. By dissolving, the odor is reduced or almost eliminated. After dissolution, it is transformed into carbon dioxide and water by fermentation under aerobic conditions.

As described above, it is considered that the mechanism of deodorization in a short period of time is that the fermentation enzyme solution is an acidic solution such as lactic acid and that the odor is adsorbed by a solvent such as alcohol which has a dissolving power. For this adsorption and solubilization,
A sufficient amount of the fermenting enzyme solution and sufficient agitation are required for the raw material manure and raw garbage. In addition, it is considered that the digestive juices of rice koji and yeast contain many enzymes, and these react immediately to deodorize, which also accelerates deodorization. In the long run, under relatively aerobic conditions, mold,

EXAMPLES The present invention will be described in detail below based on examples. In order to carry out the present invention, the inventor constructed a compost manufacturing facility as shown in FIG. 1, and prepared a fermentation decomposition promoting material which the inventors previously invented, and said compost manufacturing facility and fermentation decomposition promoting material. A compost manufacturing experiment was conducted using organic materials as raw materials using the materials, and the odor generation situation at that time was measured to confirm the odor prevention or deodorizing effect of this manufacturing method.

As shown in FIG. 1, the compost manufacturing facility is composed of a combination of a raw material receiving device 1, an enzyme decomposition treatment device 2 and a fermentation decomposition treatment device 3. The raw material receiving device 1 is composed of a raw material receiving hopper 4, a raw material quantitative cutout conveyor 5 and a raw material transfer conveyor 6. next,
The enzyme decomposition treatment apparatus 2 includes a storage tank 7 with a stirrer for storing a material for promoting fermentation decomposition of an organic substance, and an adjusting tank 8 with a stirrer,
Raw material mixing conveyer 9, agitating and mixing type enzyme reaction tank 10 for agitating and mixing the composite organic material raw material, composite organic material raw material take-out conveyor 11 prepared by sufficiently agitating and mixing, and laying the prepared composite organic material raw material It is composed of an enzymatic decomposition treatment site 12 for sufficiently performing an enzymatic decomposition action, and a composite organic material raw material transfer conveyor 13. Further, the fermentation decomposition treatment apparatus 3 is a fermentation tank 15 which is provided with a warm air blower 14 and blows air from the bottom, and a facility for performing fermentation treatment on the fed composite organic material raw material and the decomposition treatment raw material. An agitating transfer device 16 for transferring while agitating, an aged composting place 17 for placing the aged compost that has been fully decomposed and processed, a drainage tank 18 for storing and discharging the water discharged in the manufacturing process, and the fermentation tank. The exhaust device 19 is provided above the front half of the fifteen. In addition, in the exhaust device 19, the exhaust collected by the hood 20, the blower 21, and the exhaust pipe 22 is aged by the operation of the blower 21.
It is configured such that the evaporated water discharged from the bottom portion of the above into the aged compost and contained in the exhaust gas is liquefied and guided to the drain tank 18.

The fermentative decomposition promoting material was prepared specifically as follows. First, a mixture of 60 liters of rice bran and 540 liters of water is heated at 80 ° C. Next, after lowering this to 60 ℃, rice malt 180
1 liter and 60 liters of water containing a mineral component are mixed, and the mixture is left for 1 to 3 hours while keeping the mixture at about 60 ° C. to self-digest the rice koji. This self-digestion of rice koji means that starch in rice koji is made into dextrin by α-amylase, and glucose is decomposed by β-amylase or glucoamylase, and the protein in rice koji is decomposed into peptides by proteinase. , Is further decomposed into amino acids by peptidase. An enzyme digestion solution containing the product obtained by enzymatically decomposing these rice malts was prepared. Next, add 3 parts of this enzyme digestion solution.
After allowing to cool to room temperature of 0 ° C. or lower, 1.5 liters of yeast are mixed with this enzyme digestion solution and fermented at about 30 to 35 ° C. for 1 to 3 days. Then, the yeast ferments glucose and decomposes it into alcohol and carbon dioxide. In addition, lactic acid bacteria contained in rice bran ferment glucose to produce lactic acid. This organic acid such as lactic acid makes the mixed solution pH
It becomes an acidic solution of 4 ± 0.5. This was used as 830 liters of a material for accelerating fermentation and decomposition of organic matter prepared for carrying out the present invention.

The present invention implements the present invention for producing compost using the material for promoting the fermentation and decomposition of a liquid organic substance produced by the above-mentioned method, detects malodor in the production process, and The components of the compost produced in this way were analyzed.

<Example 1> First step: Rice bran or 7% of rice bran and 60 ± 10% of water were heat-treated at about 80 ° C. to 55 to 60 ° C., and koji 21% and mineral components were contained. Mixing mineral water and / or mineral water 7%, 60 ° C mainly by enzyme of koji
It was made into an enzymatic digestion solution that was saccharified and produced by self-digesting for 3 hours, cooled to room temperature below 30 ° C, and 0.2-0.5% of yeast was added to this enzymatic digestion solution to add about 30-35 ° C. Fermented and decomposed for 3 days to produce an acidic solution having a pH of about 4.0 ± 0.5 containing the produced alcohol, lactic acid bacteria and organic acid. It was configured to be stored and transferred so that a required amount of the fermentation decomposition promoting material at the time of use can be transferred to the adjusting tank 8 with a stirrer to adjust the components and the like.

Second step: As an organic material used as a raw material, 1000 k of organic raw material having a mixing ratio of pig dung 40: cow dung 60
3g of the above-mentioned prepared material for promoting the fermentation and decomposition of organic matter, 9 liters of mineral water, 1 liter of rice bran, 1 liter of rice bran, etc., and 300 kg of the matured reconstituted compost as an auxiliary material for the moisture conditioner. In addition, the whole is made into a composite organic material raw material adjusted to a water content of about 50 to 70%.

Third step: The above-mentioned organic material raw material, the material for promoting the fermentation and decomposition of organic material, the nutrient auxiliary material, and the auxiliary material for the water content adjusting material are charged into the stirring and mixing type enzyme reaction tank 10 while being mixed by the raw material mixing conveyor 9. While adjusting the temperature at 30 to 45 ° C., the mixture is stirred for 1 hour to 3 hours and mixed and prepared so that the whole composite organic material raw material becomes uniform. At this time, 30-45 ℃
It is important to adjust the temperature. This is because, when the temperature reaches 50 ° C or higher due to aerobic fermentation, temperature rise, stirring friction, etc., heat-sensitive enzymes are deactivated. In addition, when the preparation of the composite organic material raw material and the adjustment of the water content in the second step are carried out in the agitation-mixing type enzyme reaction tank 10, the nutrients are added so that a partial temperature rise due to careless aerobic fermentation does not occur. A part (about 1/3) of the auxiliary material and the auxiliary material for the water content adjusting material is charged first, and while driving the stirring / mixing mechanism of the stirring / mixing type enzyme reaction tank 10, the organic material is later used as an organic material. Gradually add the material for fermentation and decomposition while spraying, and stir and mix for about 2 hours until the whole becomes uniform. It should be noted that the enzyme in the material for promoting the fermentation and decomposition of the organic matter starts its decomposition action even during this stirring and mixing preparation and begins to enzymatically decompose a part of the raw material for the organic matter.

Fourth step: Next, the uniformly mixed and prepared composite organic material raw material is taken out, stored and accumulated in the enzymatic decomposition treatment site 12, and let stand for about 24 hours while controlling the temperature at 30 to 45 ° C. Sufficiently perform enzymatic decomposition treatment. The place where the composite organic material raw material that has been uniformly mixed and prepared is allowed to lie down may be stored in the stirring and mixing type enzyme reaction tank 10, but it is taken out as described above to the enzyme decomposition treatment site 12 where the temperature does not rise in the shade. Needless to say, it may be stored and accumulated.

Fifth step: After that, the enzyme-decomposed composite organic material raw material is put into the fermenter 15, and the warm air blower 14 is operated to ferment while blowing air from the bottom of the fermenter 15. When it is set to, the raw material is in a semi-degraded state where microorganisms can easily propagate, and it is rich in nutrients and microorganisms, and the water content is also adjusted appropriately, so that the entire composite organic material raw material Rapid aerobic fermentation stably occurs, and heat is immediately generated at 60 to 80 ° C., and vigorous fermentation decomposition treatment is efficiently performed. as a result,
A fermentation process for about 10 days can produce compost in an aged state. That is, according to the present invention, about 12 to 13 days is sufficient for decomposing an organic material raw material to produce an aged compost (organic fertilizer). This is 20 times faster than the conventional method for producing aged compost (organic fertilizer).
This means that the processing period has been significantly shortened as compared with the case where it takes about 25 to 25 days.

The components of the compost thus produced were analyzed and the results were as follows. Water 23.0% Total nitrogen 2.1% Organic nitrogen 1.9% Ammonia nitrogen 0.2% Total potassium (K ₂ O) 2.5% Total phosphorus (P ₂ O ₅ ) 5.3%

In the method for producing compost according to the present invention, the compost is decomposed in an aged state, and as described above, the nitrogen, phosphoric acid and potassium components are large in content, and thus it is of high quality as a fertilizer. Even if Komatsuna seeds were planted directly on this aged organic fertilizer, germination was 100%, and the Komatsuna grew greatly without any developmental disorder.

<Example 2> The inventor utilizes the compost manufacturing facility as shown in FIG. 1 prepared for an example of the present invention and the fermentation decomposition promoting material to carry out the above-mentioned Example 1
The odor generation situation when compost was produced from the organic matter as a raw material was measured by the above, and the odor prevention or deodorizing effect verification test of this compost production method was confirmed. The test plan is as follows.

(1) Pilot plant The compost manufacturing facility as shown in FIG. 1 is used as a pilot plant. Since the detailed description of the compost manufacturing facility has been given above, the description is omitted here.

(2) Deodorizing method A fermentative decomposition promoting material, which is a deodorizing material developed by the present inventors, is mixed into the raw material to prevent the generation of components causing an offensive odor. It is a method of suppressing the generation of a bad odor as much as possible, rather than collecting and deodorizing the generated bad odor.

(3) Deodorizing material A fermentation decomposition promoting material developed by the inventors is used. The specific manufacturing method of the fermentation decomposition promoting material prepared for the above-mentioned example has been described above, so the description thereof is omitted here, but the characteristic is that rice bran and rice koji are mixed as the main raw materials, and koji mold, yeast, It is a fermentation broth fermented using lactic acid bacteria. The fermentation liquor is an acidic solution containing ethanol, acetic acid as an organic acid, and lactic acid as main components at a pH of about 4.0 ± 0.5. It contains the above-mentioned microorganisms and extracellular enzymes produced by the microorganisms (saccharifying enzymes, proteolytic enzymes, etc.) and has the effect of improving the fermentation process of compost, and at the same time, has the effect of deodorizing. .

(4) Mechanism of deodorization When the fermentation decomposition promoting material is mixed into the organic material raw material carried into the compost manufacturing facility, the ammonia contained in the organic material raw material reacts with the organic acid contained in the fermentation decomposition promoting material. To become ammonium salt, and the volatilization of ammonia is temporarily suppressed.

Furthermore, by maintaining an aerobic condition,
This ammonium salt is immediately taken into the microbial cells as a nitrogen source for the microorganisms contained in the fermentation decomposition promoting material and used for the synthesis of microbial components (protein). That is, the fermentation decomposition promoting material contains the above-mentioned microorganism and extracellular enzymes produced by the microorganism (saccharifying enzyme, proteolytic enzyme, etc.), accelerates the decomposition of the organic material raw material, and accelerates the growth of microorganisms,
Since the organic acid ammonium salt is promptly used as a nitrogen source for the growth of microorganisms, the deodorizing effect is exerted.

In the conventional method, since the concentration of the microorganisms contained in the raw material is low, it is necessary to wait for the growth of the microorganisms because the concentration of the microorganisms is low. When mixed with a decomposition promoting material, ammonia first becomes an organic acid salt and becomes difficult to volatilize, then the saccharification / decomposition of the carbon source is promoted by the enzyme, and it is utilized for the growth of microorganisms contained in a high concentration. At this time, the ammonium salt is promptly used as the nitrogen source, so that it is possible to prevent the volatilization of ammonia, suppress the generation of odors, and effectively utilize the nitrogen source.

(5) Method of Deodorization Test The odorous component is periodically measured in the course of the method for producing a compost using the organic substance of Example 1 as a raw material. For the measurement, analysis, and evaluation of the deodorizing effect of the odorous components, ask a third party qualified for environmental measurement business. The detailed compost manufacturing method has been described above, and thus the description thereof is omitted here. The organic material raw material, which is a specific sample of the second embodiment, is a mixture having a mixing ratio of pig dung 40: cow dung 60. The odor measurement method is based on the odor prevention method step method.

(6) Deodorizing effect The deodorizing effect is considered as follows based on the odor concentration measurement result by the official method of the offensive odor prevention method.

<A. Odor at the time of adding organic material raw materials> Immediately after adding a nutrient auxiliary material and an auxiliary material for water content adjusting material to livestock excrement which is an organic material raw material to form a composite organic material raw material, the odor of the raw material is volatilized and emitted. , There is a strong smell. The main components of the bad odor at that time are ammonia, hydrogen sulfide, methyl mercaptan methyl sulfide, etc., as shown in FIG. How quickly deodorizing this is an important technical issue in composting technology that emphasizes environmental protection.

<B. Odor 2 hours after the fermentation decomposition promoting material is put into the stirring / mixing type enzyme reaction tank 10 while mixing the organic material raw material, the organic material fermentation decomposition promoting material, the nutrient auxiliary material, and the auxiliary material for the water content adjusting material on the raw material mixing conveyor. It is charged, and the temperature of the mixture is adjusted to 30 to 45 ° C., and the mixture is stirred for 2 hours to prepare a mixture of the composite organic material raw materials so that the whole mixture is uniform.
As shown in FIG. 3, the odor was greatly suppressed. Ammonia and amines, which are large amounts of malodorous constituents, are weakly alkaline, while the fermentation decomposition promoting material is an acidic solution, so the odor disappeared due to neutralization. In addition, hydrogen sulfide, sulfur-containing compounds such as methyl mercaptan, and aldehydes such as acetaldehyde are
Since a solution having a dissolving power was contained by the alcohol contained in the fermentation decomposition promoting material, the odor was solubilized in them and deodorized.

<C. 24 hours after the fermentation decomposition promoting material is charged>Odor> Uniformly mixed and prepared composite organic material raw material is taken out and stored and accumulated in the enzymatic decomposition treatment plant 12,
FIG. 4 shows the odor when the sample was left to stand for 24 hours while the temperature was adjusted to ˜45 ° C. and was sufficiently enzymatically decomposed. Almost all odors have already disappeared.

<D. Odor before / after stirring in fermenter>
Fermenter 15 is provided with the composite organic material raw material that has been subjected to the enzymatic decomposition
It is FIG. 5 that the odor before stirring was measured immediately after the mixture was put into the container and the hot air blower 14 was operated to blow the hot air from the bottom of the fermentation tank 15 to perform fermentation. FIG. 6 shows the odor measured immediately after the mixture was stirred in the fermenter 15 with a stirrer. Rapid aerobic fermentation stably occurs throughout the complex organic material raw material, and the temperature has risen to 62 ° C, but no more bad odor is emitted.

<E. Odor in the central part of the fermenter building> Fig. 7 shows the result of measuring the odor in the central part of the building in which the fermenter is installed. At the time of this measurement, the aerobic fermentation was actively performed in the fermentor, but almost no detectable odor was generated.

<F. Odor at site boundary> Fig. 8 shows the result of measuring the odor in the leeward direction of the site boundary where the building with the fermentation tank is built, and Fig. 9 shows the result of measuring the odor at the compost exit side of the site boundary. . Almost all odors are already in the odorless state, which cannot be detected, either downwind or on the compost exit side. In such a situation, there will be no complaints from the neighbors due to a bad smell.

None, stirring and mixing it until it becomes uniform while adjusting the temperature to 45 ° C. or less, thereby ensuring that the enzyme is brought into contact with the entire raw material of the complex organic substance and activating the enzyme efficiently and sufficiently. Enzymatic decomposition treatment. After that, hot air is blown into the fully organically decomposed composite organic material raw material to activate the microorganisms, whereby the fermentation and decomposition treatment is efficiently performed. In this way, enzymatic decomposition treatment and fermentation decomposition treatment are carried out in a stepwise manner, and by the synergistic effect of both treatment methods, a method for producing an organic substance in a compost that is in an aged state for a shorter period of time while preventing a bad odor. It is a basic invention that embodies the above.

Since the material for promoting the fermentation and decomposition of the organic matter contains a large amount of the fermentation enzyme produced by the microorganisms, if this material is mixed with the organic matter, the enzyme acts as a pretreatment and a part of the constituent components of the organic matter. Alternatively, it has the ability to decompose all of them in a short period of time and generate nutrients, which help and accelerate the subsequent fermentation and decomposition action by microorganisms.

Further, since the material for promoting the fermentation and decomposition of the organic matter becomes an acidic solution by the produced lactic acid and other organic acids, it neutralizes and adsorbs alkaline odors such as ammonia and amines and instantly eliminates them. Not only does it smell, but because it is a fermenting enzyme solution containing soluble water and alcohol, it has the ability to dissolve and adsorb odors of sulfides and odors of aldehydes and fatty acids. . Mixing the fermentation decomposition promoting material having such an ability with the organic material raw material has the effect of rapidly and continuously eliminating the main component of the organic material which gives off a bad odor.

The material for promoting fermentation and decomposition of organic matter decomposes organic matter in which complicated and diverse components are mixed by fermentation enzymes, or self-digests one after another to produce nutrient sources preferred by microorganisms. Activates the growth and activity of A. and synergistically enhances the fermentation promoting effect. Therefore, by utilizing the fermentation decomposition promoting material for the organic matter, the organic matter is decomposed to be harmless by a method that allows the ability of the compost to be developed well, and if the compost is manufactured, the malodor can be prevented for a short period of time. Can be realized efficiently.

Since the method for producing compost according to the present invention uses such a material for promoting the fermentation decomposition decomposition or a material for promoting the fermentation decomposition of an adaptive material, it decomposes even various and complicated organic material raw materials. Therefore, it is possible to simultaneously and efficiently realize the process of composting in a short period of time and the process of preventing and suppressing the bad odor in the decomposition process as much as possible.
