Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mineral-enriched fertilizer obtained by aerobically fermenting an organic waste while suppressing odor and the like, and replenishing a mineral which tends to be scarce, thereby increasing its utility value.

[0002]

2. Description of the Related Art Organic wastes in industrial wastes and general wastes are contaminated in various forms when left unattended. Reused. Among these organic wastes, livestock wastes, that is, manure, are the most difficult to handle and in terms of quantity. This livestock waste has already been reused in various forms. For example, in dairy and beef cattle, in addition to composting by sufficiently aerobic fermentation, simple composting of only sedimentation is performed and used relatively often in management. Pigs are sufficiently aerobic fermented to be composted or dried, but most of them do not have farmland, so they are rarely used in management. Furthermore,
Most chickens are dried, including natural drying, and are used outside of management.

The livestock waste amount is 85% for cattle and pigs.
Most of them are composted, including simple ones. Manure, which is livestock waste from cattle and pigs, is removed from the barn,
There are cases of solids such as feces + urine + litter, and cases of slurries such as manure, feces + washing water, and the like. In the case of slurries, they are solidified by various solid-liquid separation methods. These solids can be composted as they are when there is enough litter.However, in the case of separated solids mainly composed of feces or when there is only a small amount of litter and the moisture is high enough to be composted, moisture adjustment is required. Need to do. In general, inorganic materials such as straw, chaff, sawdust, bark, zeolite and perlite are used as the adjusting material. In any case, the water content of solid matter derived from cattle and pigs is reduced to about 70%, aerobic fermentation is performed in a composting facility, and composting is performed. As described above, this composting facility uses simple composting that simply deposits,
There are various types of composting that are fully mechanized and fully aerobic fermented.

[0004] The compost produced in this manner is an easily decomposable organic substance of solids and prepared materials derived from cattle and pigs, which undergoes aerobic fermentation and decomposes. To kill and stabilize. Therefore,
The compost that has been sufficiently aerobic fermented does not cause environmental pollution such as the generation of foul odors, pathogenic bacteria, and pests.
Good results can be obtained if applied to green spaces.

[0005]

The above-mentioned compost does not cause environmental pollution, and gives good results when applied to agricultural lands and green lands, and is extremely convenient. However, due to the mismatch between the compost production area and the consumption area, a new problem of surplus of compost has been generated.
In addition, it is not sufficient against environmental pollution such as odor in the process of composting waste by cattle and pigs, and complaints occur particularly in the case of simple composting. If zeolite is used as the adjusting material in terms of this odor, it can be eliminated. However, zeolite itself is acidic and works on the alkaline side by adsorbing ammonia contained in compost, but it has no neutralizing power on Japanese soil with many acidic sides, and ammonia was used as a fertilizer After that, the acidic side zeolite will be left in the soil, which is not better than the current situation in Japanese soil with many acidic sides.

[0006] Furthermore, even if the compost is made by using inorganic materials such as straw, rice husk, sawdust, bark, zeolite and perlite as waste materials for cattle and pigs, the required mineral deficiency will not occur. is there. That is, it has been a long time since the lack of minerals was pointed out in cattle and pigs,
The waste derived from it is naturally in a state of lack of minerals, and even if inorganic materials such as zeolite and pearlite are added to the above-mentioned adjusted materials, these zeolites and perlite have a good balance of all the minerals required by animals and plants. As it does not, it does not eliminate the mineral deficiency in the resulting compost. For this reason, compost is not always of good quality, and it is difficult to eliminate the mismatch between the compost production area and the consumption area in terms of transportation costs, and it is necessary to work hard to dispose of excess compost. I have.

Accordingly, the present invention has been made in view of the above circumstances, and has no environmental pollution such as odor in the process of composting organic waste such as livestock waste, and is alkaline.
Moreover, it is an object of the present invention to provide a high-quality mineral-enriched fertilizer containing minerals required by plants in a well-balanced manner.

[0008]

Means for Solving the Problems The present inventors have long been investigating and studying the composition and properties of shell fossils that have gas and liquid absorptivity and can supply minerals at the same time. We have been conducting research on the environmental conservation of farms and the use of livestock waste and its use as fertilizer. As a result, it is essential to protect the environment of the breeding site, and in particular to effectively treat and dispose of livestock waste, for livestock breeding, including livestock manure, which has been regarded as a pollutant that has led to environmental pollution. Is composted by the aerobic fermentation effect by adding the mineral effect and physicochemical effect of shell fossils, and the compost is reduced to green farmland, and it is organic, safe and high quality without worrying about complex pollution such as environmental hormones. It makes sense to maintain and expand the production of agricultural products, create a recycling-oriented production structure, and produce agricultural products that truly meet the consumer's position, creating an ideal regional recycling-oriented social structure for the next century. Therefore, we have conducted intensive research on how to make a fertilizer on an organic resource recycling system as described above. As a result, if fossil shellfish is immediately added to and mixed with waste from livestock and the mixture is aerobically fermented and composted, it can be put on an organic resource recycling system that contains no odor, contains weak alkalis, and contains minerals in a well-balanced manner. The present inventors have found a new use aspect of shell fossils that can obtain easy fertilizer, and have reached the present invention.

[0009] That is, the invention of claim 1 is to dispose of shell fossils, which are humus-soluble crystals, in which various nekton, plankton, algae, seaweed, etc. made of calcareous or silicic acid are buried and deposited. It is a mineral-enriched fertilizer characterized by being added to and mixed with a substance, adjusting the water content, adsorbing odors and the like, and aerobically fermenting the mixture.

[0010] The mineral-enriched fertilizer of the present invention is obtained by adding and mixing shell fossils, which have a gas or liquid adsorbing property and are themselves a mineral donor, to organic waste and aerobic fermentation of the mixture. . Here, the organic waste is not particularly limited as long as it contains a readily decomposable organic component. Therefore, even if the organic waste does not contain the easily decomposable organic component, if it is mixed with the organic waste containing the easily decomposable organic component, the organic waste contains the easily decomposable organic component. It is organic waste.
However, since this organic waste finally becomes a fertilizer, it can be used on condition that those containing harmful substances that are not suitable as a fertilizer are finally removed.

[0011] The above-mentioned organic waste is exemplified by cows, pigs,
Livestock waste such as chicken, sewage sludge, human waste sludge, food industry drainage sludge, fish farm bottom mud, organic sludge such as aoko and lake bottom mud, beer cake, shochu cake, okara, sugar-making residue, fruit juice residue, Food processing residues such as coffee grounds, tea grounds, livestock processing residues, fishery processing residues, pulp waste liquor, bark, sawdust,
Forest dust and plant residues such as chip dust, pruned branches and leaves, bagasse, chaff, straw, etc., garbage (commonly known as "garbage"), city-collectable combustible waste, and household waste such as business-related waste.

The shell fossils used in the present invention are foraminiferal fossils in the archaeological name and calcareous sandstone in the geological name. In Japan, high quality ones are produced in Noto Peninsula, Toyama Prefecture and Ishikawa Prefecture, and also in various places. However, there is no limitation according to the place of production. Shell fossils from any locality may be used as long as the shell fossils have the following characteristics. Table 1 shows the analytical values of shell fossils in the main production areas.

More specifically, the shell fossils of the present invention are based on the following quantitative analysis table (Table 2) of samples mined at several mines in Toyama Prefecture, and mined from these mines. An analog of the fossil shell of the ingredients shown in Table 2,
It is.

[0014]

[Table 1]

[0015]

[Table 2]

The shell fossils mined in Toyama Prefecture differ greatly in the molecular composition from those of shell fossils mined in other parts of Japan. Is characterized by a very high content of. In addition, this fossil shell has an aragolite-type crystal structure secreted from the living body, and has numerous counts of pores having a certain effective diameter, and the countless pores include and do not include water of crystallization. There are various cases. These pores that do not contain water of crystallization have adsorption performance similar to activated carbon, and may exhibit tens of times the capacity of activated carbon depending on the type of the substance to be adsorbed. Accordingly, shell fossils having many small pores containing no crystallization water are effective for absorbing odors and the like, and heat-treated shell fossils from which crystallization water is removed by a heat treatment described later in detail are often used.

The particle size of the shell fossils is not particularly limited, but it is generally preferable that the particle size be small. However, the particle size of the shell fossils is mainly taken into consideration from the adsorption performance of the shell fossils and the mineral supply performance. There is a need. In other words, the smaller the particle size of the shell fossil, the greater the specific surface area and the better the mineral supply performance, but if the particle size is smaller than the small holes that adsorb odors, etc., there is no meaning in the adsorption performance, and the crushing cost also increases I do. On the other hand, if the particle size is too large, the specific surface area becomes too small, the mineral supply performance and the adsorption performance are also reduced, and in addition, it becomes difficult to uniformly disperse the fossil shellfish in the organic waste. Therefore, the particle size of the shell fossil is preferably 0.5 μm
８００800 μm, more preferably 74 μm〜400.
μm, and at least 0.5 μm to 800 μm
When the particle size distribution is within μm, it can be easily added to and mixed with the organic waste, and the uniform dispersion, the effect of adsorbing odors and the like, and the effect of supplying minerals can be simultaneously satisfied in a well-balanced manner, and its performance can be easily maintained.

The mineral-enriched fertilizer of the present invention is obtained by adding and mixing shell fossils to organic waste and aerobically fermenting the mixture. Egg shells, shells, shrimp and crab shells, fish bones and scales, biological minerals derived from living organisms such as bones of terrestrial animals, and processed products of these biological minerals are added as auxiliary agents and bulking agents, Attempts to enhance performance are within the scope of the present invention. That is, among the above-mentioned biological minerals and their processed products, the egg shell is described in detail as 98%
% Is mineral, and about 95% of the mineral is CaCO ₃ ,
In addition, it contains a small amount of MgCO ₂ and Ca (PO ₄ ) _2, and the egg shell is finely powdered. When viewed with an electron microscope, it has a myriad of holes and a porous structure. Therefore, the egg shell powder has an adsorptive property and is itself Ca, M
Since it can also be a supplier of g and P, it can be an adjuvant and a filler for shell fossils. Other biological minerals and processed products thereof are almost the same as those in the case of egg shells, so that they have an adsorptive property and themselves become a mineral supplier, and can be an auxiliary and extender for shell fossils.

Further, the properties of the mineral-enriched fertilizer of the present invention, that is, the properties of being free from environmental pollution such as odors, being alkaline, and containing the minerals required by plants in a well-balanced manner, are not limited. May be added, and such a case is also within the scope of the present invention.

The mineral-enriched fertilizer of the present invention is produced by adding and mixing shell fossils to organic waste and aerobic fermentation.
At this time, the heat generated by the decomposition of the easily decomposable organic components contained in the organic waste raises the temperature of the organic waste, and the temperature rise raises the operating conditions of the microorganisms responsible for the decomposition, resulting in more active decomposition. There is a causal cycle that progresses. Therefore, in the production of the mineral-enriched fertilizer of the present invention, it is necessary to condition such that the above-mentioned circulation of causation occurs. At the same time, easily decomposable organic components of organic waste
It easily rots and produces odors and harmful substances, which must be stopped. Hereinafter, the most typical composting for producing fertilizer by aerobic fermentation of organic waste will be described.

The specific production of mineral-enriched fertilizers will vary greatly depending on the nature of the organic waste. Therefore, first, it is investigated whether or not organic waste can be used as a compost material, and it is confirmed that there is no obstacle to composting such as presence of harmful substances and content of easily decomposable organic components. Next, the organic waste is preconditioned. This preconditioning is the creation of conditions for composting organic waste smoothly. Therefore, for example, if the organic waste has already spoiled to produce odors and harmful substances, the spoilage of the organic waste should be immediately changed to maintain the health of workers and affect the local residents. Adding and mixing fossils to adsorb odors and harmful substances is one precondition. Further, if the organic waste is easily perishable, fossil shellfish may be added and mixed immediately at the time of disposal to adsorb odors and harmful substances in advance. Generally, when organic waste is deposited from the viewpoint of facilities and operation, appropriate voids are generated, and addition and mixing of shell fossils is performed as part of preconditioning for allowing air to flow.

In this pre-adjustment, for example, in the case of excess moisture such as livestock waste without litter, there is no void and no accumulation is possible. The adjustment material is added and mixed as a water content adjustment so that an appropriate void can be maintained and deposited. Conversely, in the case of organic waste such as dried vegetable waste, it can be deposited, but there are too many voids and there is insufficient moisture to prevent composting. Is given. In addition, since the adjustment material used in the pre-adjustment is finally a mineral-enriched fertilizer, the adjustment material itself must be reducible to farmland and green space.

At the time of this pre-conditioning, as described above, shell fossils are added to the organic waste, and the amount of addition is 0.2 to 15% by weight based on the pre-conditioning organic waste. It is preferable to add the shell fossils. If the content is less than 0.2% by weight, it is difficult to confirm the effect of adding the shell fossil, and if it exceeds 15% by weight, it is difficult to expect an effect corresponding to the cost increase.
Note that the shell fossils can naturally also serve as the adjustment material at the time of the pre-adjustment.
That is, shell fossils have a myriad of small holes and are porous as described above, and also have a hygroscopic property, so that they can also serve as a material for adjustment. Therefore, when adding the shell fossil to the organic waste, it is necessary to determine the addition amount of the shell fossil and other adjustment materials in consideration of the function as the adjustment material. In any case, the shell fossils need to be added to the organic waste before finally becoming a mineral-enriched fertilizer. Thereby, odors and harmful substances due to the organic waste can be adsorbed so as not to affect others.

The organic waste after the preconditioning is rich in easily decomposable organic substances, has a moderate air permeability, and has a sufficient amount of water. Due to forced ventilation, aerobic fermentation begins,
Circulation of the above-mentioned causal effect proceeds, fermentation further proceeds by appropriate switching, temperature rises, water is removed, pathogenic bacteria and pests are killed, and primary fermentation is terminated. Depending on the situation of application, the immature mineral-enriched fertilizer whose primary fermentation has been completed may be directly applied to agricultural land and green space, or may be further fermented and fully matured to form a complete mineral-enriched fertilizer,
May be applied to green spaces.

Since the mineral-enriched fertilizer is a mixture of organic waste and fossil shellfish, the fertilizer exhibits the adsorptive properties of the shell fossil at that time, and the odor from the organic waste,
Adsorbs harmful substances and adsorbs moisture. Therefore, the myriad pores of the shell fossils during fermentation also serve as a conditioning material at the time of preconditioning of the organic waste, and serve as a suitable habitat for the fermenting fungi and promote the fermentation. If this mineral-enriched fertilizer is applied to agricultural lands and green lands, it means that fertilizer with good mineral balance has been scattered, and the added shell fossils are weakly alkaline. Crop can be harvested.

According to a second aspect of the present invention, in a fermented product obtained by aerobic fermentation of an organic waste, various nekton, plankton, algae, seaweed and the like made of calcareous or silicic acid are buried and deposited to have humus solubility. It is a mineral-enriched fertilizer characterized by mixing shell fossils, which are crystalline materials.

[0027] The mineral-enriched fertilizer of the present invention indicates that a fermented product obtained by aerobic fermentation of an organic waste and the shell fossil may be mixed to obtain the fermented product. Mix 0.5-30% by weight of shell fossils. If the amount is less than 0.5% by weight, it is difficult to confirm the effect of adding the shell fossils, and if it exceeds 30% by weight, it is difficult to expect an effect corresponding to the cost increase. The mineral-enriched fertilizer is substantially the same as the mineral-enriched fertilizer according to the first aspect of the present invention. The easily decomposable organic matter of the organic waste is relatively stable and does not emit odors and harmful substances. It is effective when it is something like this.

According to the invention of claim 3, the soil not contaminated by the pathogenic bacteria, the organic waste, and various nekton, plankton, algae, seaweed, etc. made of calcareous or silicic acid are buried and deposited to have humus solubility. Mixed with the shell fossils
The mineral-enriched fertilizer is characterized in that the mixture is aerobic fermented while also controlling moisture and adsorbing odor and the like.

The mineral-enriched fertilizer according to the present invention is commonly called "bokashi manure", and is mixed with various organic wastes in soil, sedimented and ripened, and is derived from organic wastes before being applied to agricultural land. It is a fertilizer with excellent physicochemical and microbial properties by adapting fertilizer nutrients to the soil. here,
Mountain soil is normally used as soil that is not contaminated with pathogenic bacteria, but the soil that has accumulated on the side of the road, called "frost lands," is considered the highest. Above this "frost collapse", the frost pillar that was frozen in the severe cold and floated on the slope was frozen and thawed, and it was a smooth soil that collapsed in sunlight and was excellent in water absorption and permeability without stickiness. In addition, as the above-mentioned soil, field soil, paddy soil, soil from a water purification plant, soil from a quarry, etc., which are relatively less contaminated with pathogenic bacteria since feed crops are cultivated, are used.

As the organic waste here, the above-mentioned organic waste can be used, and in this case, rice bran is preferably contained. The reason is that rice bran promotes the propagation of microorganisms and has a large fermentation promoting effect. It is necessary to add at least 1% by weight or more of rice bran to soil. The upper limit is generally about 15% by weight. As the organic waste other than rice bran, the same as described above is used, but the amount of addition should be changed depending on the crop to be applied. In addition, shell fossils
As described above, the adsorbent of shell fossils is used, and it absorbs odors and harmful substances from organic wastes and adsorbs moisture. It works to promote fermentation.

And soil not contaminated by pathogenic bacteria;
Organic waste containing rice bran, fossil shellfish, and mineral-enriched fertilizer that has already been made as a seed fungus are mixed and deposited while adjusting the water content. In winter, 3-4 months,
If natural ventilation or forced ventilation is performed for about 1.5 months in summer, a mineral-enriched fertilizer commonly called "bokashi manure" can be obtained. If this mineral-enriched fertilizer is applied to farmland and green space, it means that fertilizer with good mineral balance is scattered,
Since the added shell fossils are weakly alkaline, it is possible to neutralize acidic soil and improve the soil while also suppressing damage from pests and harvesting good crops. In addition, even if soil not contaminated by pathogenic bacteria is added during the process of compost production, "Bokashi manure"
A mineral-enriched fertilizer similar to that of.

According to a fourth aspect of the present invention, there is provided a mixed fermented product obtained by mixing soil not contaminated with pathogenic bacteria with organic waste, adjusting the water content, adsorbing odors, and aerobically fermenting the mixture. A mineral-enriched fertilizer comprising a mixture of fossil shells, which are humus-soluble crystalline materials, in which various nekton, plankton, algae, seaweed, and the like made of calcareous or silicic acid are buried and deposited. .

The mineral-enriched fertilizer according to the present invention is obtained by mixing the fossil shell with a mixed fermentation product obtained by aerobic fermentation of a mixture of soil not contaminated with pathogenic bacteria and organic waste. It is shown that the mixture fermented product is mixed with 0.25 to 10% by weight of shell fossil. 0.2
If it is less than 5% by weight, the effect of adding shell fossils is difficult to confirm, and if it exceeds 10% by weight, it is difficult to expect an effect commensurate with the cost increase. In addition, this mineral-enriched fertilizer
It is almost the same as the mineral-enriched fertilizer according to the third aspect of the invention, and is effective when the easily decomposable organic matter of the organic waste is relatively stable and does not emit odor or harmful substances. It is.

According to a fifth aspect of the present invention, the shell fossil is a mineral-enriched fertilizer in which water of crystallization contained in its pores is removed by heat treatment.

Shell fossils from which water of crystallization has been removed by heat treatment, that is, heat-treated shell fossils, are obtained by heat-treating unheated shell fossils in the range of 150 ° C. to 300 ° C. Water has been almost completely removed, the adsorption performance has been enhanced, and heat treatment has killed various bacteria adhering to unheated shell fossils. In other words, the heat-treated shell fossil has improved adsorption performance and further kills various bacteria by removing the water of crystallization contained in the pores, so that there is no adverse effect during aerobic fermentation.

[0036]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below in detail. First, investigations and tests for confirming various effects of the mineral-enriched fertilizer having the above configuration were performed, and the situation will be described. Example 1 First, a laboratory test is performed on the deodorizing properties of shell fossils. The details of the test are as follows. Put 0.5 g of powdered shell fossils in each 1 liter bag,
Further, each odor gas whose concentration was simply adjusted, that is, ammonia, acetaldehyde, acetic acid, hydrogen sulfide, and trimethylamine were sealed, and the initial concentration of each odor gas, after 30 minutes and after 60 minutes, was measured by Gas Tech. It is measured with the detector tube for each odor gas. In addition, ammonia, acetaldehyde, and acetic acid are also measured for activated carbon by the same method for comparison. Table 3 shows the results.

[0037]

[Table 3]

According to Table 3, sufficient odor gas other than acetaldehyde can be removed, and the odor gas has almost the same removal ability as activated carbon.

[Embodiment 2] Next, measurement on an actual scale is performed. Spray 500 g of fossil shellfish per cow per day on cow beds, bank cleaners, urinary ditches, and passages. For the most influential ammonia among the above odor gases, before spraying, immediately after spraying, one week after spraying, spraying 2 After three weeks, the concentration after three weeks of spraying was measured using No. Measure with a 3L detector tube. Table 4 shows the test results.

[0040]

[Table 4]

When the ammonia odor becomes 2 ppm or less,
Ordinary people do not feel the odor, so spraying the shell fossils reduced the odor to almost no ammonia odor.

Example 3 A straw was placed in a poultry house of 100 tsubo and 900 kg of powdered shell fossils were sprayed on the straw.
No. 00 chicks were placed, and the ammonia concentration in the poultry house after 49 days and 55 days was measured using a No. Measure with a 3L detector tube. [Comparative Example 1] In the state where the powdered shell fossils were not sprayed, the ammonia concentration in the poultry house was measured by Gastech No. Measure with a 3L detector tube. Table 5 shows the test results.

[0043]

[Table 5]

By spraying 9 kg of powdered shell fossils per square meter, 2 ppm even after 49 days and 55 days in total
The following is an extremely favorable environment. It can then be composted with the litter.

Example 4 A beef barn was laid with a litter of sawdust, a beef was raised on the litter, and manure was absorbed into the litter. About 500 kg of the litter was taken out and used as a compost material.
At this time, the water content of the compost material was 71% on average at three locations. 20 kg (addition rate 4% by weight) of powdered shell fossils are added to and mixed with this compost material, piled up in a mound, cut back every two days, and fermented for two months (March / April) to be mineral-enriched fertilizer.

[0052]

As described in detail above, the mineral-enriched fertilizer of the present invention has the following effects. Claim 1
The invention of the present invention exhibits the adsorptivity of shell fossils at the time of adding and mixing shell fossils to organic wastes, adsorbs odors and harmful substances from organic wastes, adsorbs moisture, and removes organic wastes. During fermentation, the innumerable holes of the shell fossils serve as a good home for fermenting bacteria and promote fermentation during fermentation. Therefore, there is no environmental pollution such as odor in the process of composting organic waste such as livestock waste, and if this mineral-enriched fertilizer is applied to farmland and green space, it is possible to spread fertilizer with good mineral balance. Since the added fossil shells are weakly alkaline, good crops can be harvested while neutralizing the acidic soil and improving the soil.

According to the second aspect of the present invention, the same effects as described above can be obtained even if the organic waste is first subjected to aerobic fermentation and the fermented product is mixed with fossil shellfish.

According to the third aspect of the present invention, the fertilizer component contained in the organic waste is adapted to the soil before being applied to agricultural land by mixing and fermenting the organic waste and shell fossils in the soil. It is easier to adapt to antagonism and symbiosis with microorganisms. Therefore, in addition to the above effects, there is an effect that it is easy to avoid damage from soil diseases and pests.

According to the fourth aspect of the present invention, the same effect as described above can be obtained by mixing shell fossils with a mixed fermented product obtained by mixing and fermenting organic waste containing rice bran in soil.

According to the fifth aspect of the present invention, since the heat treatment is performed, more powerful adsorption performance is imparted, and the above effect is further enhanced.
