(Point of attention)
According to the “2012 Malodor Prevention Law Enforcement Status Survey” published by the Ministry of the Environment, as shown in Non-Patent Document 1 (1), out of 14,411 cases of malodor complaints, “outdoor incineration” is the highest with 28.0%. Then, next, "service industry, other" (15.3%), "individual house, apartment, dormitory" (11.1%), "livestock industry" (10.1%), "other manufacturing industry" (8 .2%), “sewage and water supply” (4.3%), “food manufacturing industry” (4.1%), “construction work site” (2.4%), “feed and fertilizer manufacturing plant” 2.0%), “chemical plant” (1.4%), “others” (12.9%), and reports on their odor sources.

    According to this survey, it is ranked fourth in the top for odor smell complaints (10.1%) caused by "livestock industry" in Japan, and it is considered that odors that are caused by livestock relations have been dealt with However, it still remains a major environmental problem, and the average over the past 10 years is no different from 10.1%, and this fact does not mean that the problem of the bad smell of “livestock industry” has been resolved However, even now, it means that the establishment of technology to prevent odor is urgently needed, and more specifically, for “service industry and other” and “personal housing, apartment and dormitory,” the second and third place respectively. It can be seen that it is occupied and raw garbage and odor from the toilet have become a major environmental problem.

    Referring to Non-Patent Document 1 (2), the main source of offensive odor in the livestock industry is feces and urine of livestock (feces + urine + wash water). Odor from feces and urine is a gas that will be generated when anaerobic microorganisms degrade their organic matter when placed under anaerobic conditions with low oxygen. There are 12 types of offensive odor gas subject to the regulation of the Odor Prevention Law, and their names (evidence type), water solubility difficulty (acid and alkaline), and regulatory values are as follows: .

1) Ammonia (NH ₃ ): water soluble (alkaline), 1 to 5 ppm
2) Methyl mercaptan (CH ₃ SH): poorly soluble in water, 0.002 to 0.01 ppm
3) Hydrogen sulfide (H ₂ S): water soluble (weakly alkaline), 0.02 to 0.2 ppm
4) Methyl sulfide ((CH ₃ ) ₂ S): Poor water solubility, 0.01 to 0.2 ppm
5) Methyl disulfide (CH ₃ S ₂ CH ₃ ): poorly water-soluble, 0.009 to 0.1 ppm
6) Trimethylamine (N (CH ₃ ) 3): water soluble (alkaline),
0.005 to 0.07 ppm
7) Acetaldehyde (CH ₃ CHO): water soluble (acidic), 0.05 to 0.5 ppm
8) Styrene (C ₆ H ₅ CH = CH ₂ ): poorly water-soluble, 0.04 to ₂ ppm
9) Propionic acid (CH ₃ CH ₂ COOH): water soluble (weakly acidic), 0.03 to 0.2 ppm
10) Normal butyric acid (CH ₃ (CH ₂ ) ₂ COOH): water soluble (weakly acidic),
0.001 to 0.006 ppm
11) Normal valeric acid (CH ₃ (CH ₂ ) ₃ COOH): water soluble (weakly acidic),
0.0009 to 0.004 ppm
12) Isovaleric acid ((CH ₃ ) ₂ CHCH ₂ COOH): water soluble (weakly acidic),
0.001 to 0.01 ppm

    If these 12 types are classified according to the regulated offensive odor gas, the poor water solubility is 4 types of methyl mercaptan, methyl sulfide, methyl disulfide and styrene, and the remaining 8 types are all water soluble and their acidity is The degree is 3 kinds of alkalinity and 5 kinds of acidity. The offensive odor in the livestock industry includes all of these 12 types, so the deodorizing method in the livestock industry is not a single treatment but a combined treatment method.

(Prior art)
As described in Non-Patent Document 1 (2), methods for preventing malodor in the domestic livestock industry are known as follows.
1) Deodorizing agent: Oxidizing agent (for example, ozone), neutralizing agent (lime), masking agent (perfume), condensing agent (methaacrylate), adsorbent (activated carbon), enzyme agent (digestive enzyme) and the like.
2) Aerobic / anaerobic treatment: Composting, aeration, methane fermentation.
3) Drying method: firepower, sun, fermentation.
4) Combustion deodorization method: Direct combustion method, catalytic oxidation method.
5) Chemical solution deodorization method: Hypochlorous acid soda.
6) Biological deodorization method: Bio filter (soil, compost, peat), bio scrubber (activated sludge).

If the past measures to prevent malodor are evaluated, 1), 3), 4), 5) and 6) are considered to be effective in a small enclosed space, but large-scale management is possible in pig farming and poultry farming Deodorization of a large amount of excrement excrement that is excreted every day requires a large-scale closed space, which may cost enormous costs. The aerobic treatment method (composting and aeration) of 2) requires a large amount of air, can not maintain a closed space, and is prone to offensive odors in the treatment process. Moreover, in the case of the anaerobic treatment method (methane fermentation) of 2), although it is effective in small-scale livestock industry, the malodor measures of the digestive juice after methane fermentation can not be done. Furthermore, although 1) to 5) is directed to the deodorization of manure and waste water discharged from all the stalls, it does not cope with the offensive odor from inside the stalls. Also, among these, 1) and 2) remain uneasy about the safety of the deodorizing agent or the deodorizing method to be used for animals and humans.

(Awareness of problems)
As mentioned above, the existing deodorization measures in the livestock industry both have drawbacks, and the creation of groundbreaking deodorizing technology is strongly desired, and it is an urgent issue, and the main points are 1) low cost and simplicity Being able to deodorize by 2 methods, 2) being able to deodorize inside the barn, 3) to be safe for livestock and people of deodorizing agents and deodorizing methods, 4) to be able to cope with various types of odor gas, 5) to have antibacterial effect 6) It can be applied to the deodorization of human excrement and sewage, and 7) It can be applied to the offensive odor from the residue of plants and food.

(Object of the Invention)
Therefore, the present invention is a deodorizing method that easily and safely suppresses various kinds of odors and bacteria generated from animal or human excrement, urine, washing sewage, and plant or food residue in order to solve those problems.・ Based on the judgment whether it is impossible to develop new deodorizing and antibacterial technology capable of producing an antibacterial agent, we start its development and research quickly and repeat trial and error over a long period of time and many trial manufactures and experiments. As a result, this time, finally, the deodorizing method by the undiluted deodorization liquid solution using the calcium ion complexing liquid of the new constitution which achieves the deodorizing and antibacterial effect by the combined use of the calcinated shellfish and the organic acid is realized. In particular, the construction of the present invention will be described in detail along with the representative embodiments of the present invention shown in the drawings.

(Structure of the Invention)
As clearly understood from the representative examples of the present invention shown in the drawings, the deodorizing method by the stock solution for deodorization using the calcium ion complexed liquid of the present invention basically comprises the following constitution. There is.
That is, a calcium-containing compound, an organic acid and water are mixed in appropriate proportions, and the hydrogen ion concentration is adjusted to be acidic. The deodorizing dilution liquid diluted to an appropriate value within 1,000 times the stock solution and adjusted to either acidic or neutral is sprayed and applied to the object and the object space to deodorize it. The deodorizing method is a summary .

More specifically, the deodorizing method consisting of this basic constitution is mixed at a ratio of 20 g of calcium oxide powder, 46 g of an organic acid and 1 L (liter) of water, and adjusted so as to make the hydrogen ion concentration acidic. For deodorization by diluting the stock solution for deodorization using calcium ion complexing solution with water or distilled water to an appropriate value within 1,000 times the stock solution and adjusting it to either acid or neutral It becomes the deodorizing method which consists of composition which spreads and applies dilution liquid to object and object space, and deodorizes it.

In other words, calcium ion was prepared such that the microscopic structure (molecular crystal structure) is a mixture of calcium oxide powder of biological origin which is a olivine crystal body and an organic acid, and the hydrogen ion concentration is made acidic. Water or distilled water, the stock solution for deodorization using the complexed solution is diluted to an appropriate value within 1,000 times the stock solution, and the diluted solution for deodorization prepared by adjusting to either acidic or neutral is the target And it could be said that it is a deodorizing method that was applied to the target space to deodorize it .

If specific examples are shown, at least one of salmon, chicken egg shell and shell is crushed to a maximum width of 0.1 mm or less, and calcined at 500 ° C. to 1,500 ° C. The calcium powder is mixed with an organic acid , and adjusted to make the hydrogen ion concentration acidic. The stock solution for deodorization using a calcium ion complex solution is prepared with water or distilled water. The deodorizing method is such that the deodorizing dilution liquid, which is diluted to an appropriate value within 2,000, and adjusted to either acidic or neutral, is applied to the object and the target space to deodorize it.

More specifically, a scallop shell which is natural or aquaculture and is sufficiently desalted is crushed to a maximum width of 0.1 mm or less, calcined at 500 ° C. to 1,500 ° C., and the main component is calcium oxide An organic acid is mixed with the calcium powder to be treated, and the stock solution for deodorization using the calcium ion complex solution, which is adjusted to make the hydrogen ion concentration acidic, is a stock solution with water or distilled water. Deodorizing method consisting of applying deodorizing dilution liquid diluted to an appropriate value within 1,000 times and adjusted to either acidic or neutral to the object and target space to deodorize It can be said.

    As described above, according to the calcium ion complexing solution of the present invention, the mixing ratio of calcium and citric acid can be easily changed from the characteristic constitution as described above, unlike the conventional one. In addition, the hydrogen ion concentration (pH) can be freely adjusted by diluting with water, whereby an aqueous solution suitable for deodorization and an aqueous solution suitable for antibacterial activity can be produced inexpensively and simply, and feces of animals or humans. And various types of odorous gases and bacteria generated from urine, washing wastewater, and plant or food residues, even in small amounts quickly and effectively, and the effect is sustained for a long time, yet complexed and chelated. We can offer a wide range of industries the deodorizing and antiseptic solutions that are harmless to animals and plants and have high safety, and the deodorizing and antibacterial methods that use them Refers outstanding features are those obtained.

In addition, calcium oxide powder, more specifically, bio-derived calcium oxide powder whose microscopic structure (molecular crystal structure) is a stellate crystal, dramatically promotes complexation of calcium ion by mixing with citric acid, Higher deodorization and sterilization effects can be achieved, and at least one of salmon, chicken eggshell and shell is crushed to a maximum width of 0.1 mm or less, and 500 ° C to 1,500 ° C, Desirably, calcium powder which is fired at 1,000 ° C. and whose main component is calcium oxide, more specifically, a scallop shell which is natural or cultured and which has sufficiently removed salt content, having a maximum width of 0.1 mm or less The powder is ground and calcined at 500 ° C. to 1,500 ° C., preferably 1,000 ° C., and calcium powder whose main component is calcium oxide is used as a raw material. Can economically utilize scallop shells, which must be treated as industrial waste, as an active ingredient, and by using bio-derived ingredients it is extremely safer and adversely affects humans, animals, plants, etc. Not only that, but there is a high possibility that it can be used for various applications, such as providing nutritional supplementation such as supplementation of calcium component and supplementation of citric acid component and fertilization, etc. A remarkable effect is obtained by comparison.

    The deodorizing stock solution of the present invention can be efficiently mass-produced simply by mixing calcium, an organic acid and water in an appropriate ratio and adjusting the hydrogen ion concentration to an acidity, and stably for a long time It can be made storable, and the stock solution for deodorization is diluted with water or distilled water to a stock solution to 1,000 times, preferably 50 to 500 times, and made acidic or neutral. The deodorizing solution based on the deodorizing method of the present invention, in which a diluted solution for deodorization can be easily prepared by adjustment and applied to an object and a target space, etc., can be remarkably safely and efficiently It can be done and can greatly improve the economics.

Furthermore, the antibacterial stock solution of the present invention can be efficiently mass-produced simply by mixing calcium, an organic acid and water in an appropriate ratio and adjusting the hydrogen ion concentration to be alkaline, and stably for a long time In addition to being able to be stored, the antibacterial stock solution is diluted with water or distilled water to a stock solution to 20 times , preferably 5 to 10 times , and adjusted to alkalinity to be simply an antibacterial dilution liquid Can be manufactured, and the antibacterial work based on the antibacterial method of the present invention, which is disinfected by spreading and applying to an object and a target space, can be carried out much more safely and efficiently, and further economic efficiency can be achieved. It can be enhanced.

    On the other hand, the calcium ion complexing solution of the present invention, the stock solution for deodorization using the same, the stock solution for the same, etc. store the deodorizing agent and the antibacterial agent as a stock solution until before and spray and apply the stock solution as it is However, the stock solution for deodorization and the stock solution for antimicrobials can be increased in the process of adjusting the hydrogen ion concentration by diluting them with water according to the purpose of use, respectively. Rich, and even with small amounts it has the unique property of sustaining high effects for a long time, so when the wide area of the facility has to be safely deodorized and disinfected, such as livestock sheds in the livestock industry, etc. It will have a great effect of being able to be stored and used efficiently and economically.

In the practice of the present invention having the constitution as described above, the description will be added on its best or desirable mode.

As such, the scallop shell, which is natural or cultured and sufficiently desalted, is ground to a maximum width of 0.1 mm or less, preferably 500 ° C. to 1,500 ° C. Was sintered at 1,000 ° C., is good and that the main component and calcium oxide.

    The organic acid is the main material of the calcium ion complexing solution of the present invention, has the function of complexing calcium ion by mixing with calcium oxide powder, and having the function of neutrality to acidification when the mixing ratio is increased. It is advantageous to use at least one of citric acid and carboxylic acid having a carboxyl group (-COOH) such as lactic acid.

Water is a main material of the calcium ion complexing solution of the present invention, and calcium and organic acid of the calcium ion complexing solution can be mixed to form a calcium ion complex without adversely affecting deodorization and antibacterial function. It also has the function of diluting and adjusting the stock solution for deodorization and the stock solution of the present invention of the present invention to approach neutrality from either the alkaline or acidic state, and also capable of increasing the volume. It is preferable to use one which contains as little mineral component as possible, and it is preferable to use pure water by filtration or distilled water as shown in the examples described later.
In the following, the structure will be described in detail along with embodiments representative of the present invention shown in the drawings and tables.

The drawings show some representative examples embodying the technical concept of the deodorizing method by the stock solution for deodorization using the calcium ion complexing solution of the present invention.
It is the molecular structure figure which showed the calcium ion complexing liquid based on the molecular orbital method (MO). It is an electron microscope image photograph of scallop-derived calcium oxide. It is a photograph which shows the experimental result at the time of an antimicrobial method start. It is a photograph in which an antimicrobial method (specimen 1) stock solution use and an experimental result after 24 hours under room temperature are shown. It is a photograph which shows the experimental result after 24 hours under room temperature using an antibacterial method (specimen 2) 5-fold dilution liquid (dilution water: distilled water). Antibacterial method (specimen 3) 10 It is a photograph showing an experimental result after 24 hours at room temperature using the dilution liquid (diluted water: distilled water). Antibacterial method (control) It is a photograph which shows the experimental result after 24 hours under room temperature.

In the case shown in FIG. 1, a scallop shell which is natural or aquaculture and which has been sufficiently desalted is crushed to a maximum width of 0.1 mm or less and fired at 500 ° C. to 1,500 ° C., preferably 1,000 ° C. And calcium oxide containing calcium oxide as the main component, mixed with an organic acid, complexed with calcium ions, and added with an appropriate amount of water to make it one of acidic, neutral or alkaline. The representative example of the calcium ion complexing solution of the present invention, in which the ion concentration (pH) is adjusted, is shown.
Hereinafter, the constitution of the calcium ion complexing solution of the present invention will be described according to the method for producing it.

(1) Production and component of calcined calcium powder shell The shell which is calcium oxide powder which is the main component is natural or aquaculture, and it is exposed to rain water for a long time to remove salt, and the maximum width is 0.1 mm. Crushed at a temperature of 1,000 ° C., the main component is calcium oxide (CaO), and as shown in FIG. It can be called calcium powder.

The shell is not particularly limited as long as it is in the form of sea bream or brackish water or fresh water such as scallops, oysters, clams, clams and crows. The components of a fired powder (1,000 ° C.) using a scallop shell as an example are shown in Table 1.
The weight loss of the test preparation due to high heat (about 30 minutes at 600 ± 25 ° C.) was 46%. As a result of detailed analysis, it was found that this loss was small due to carbon dioxide (CO ₂ ) and mostly due to water (H ₂ O). Therefore, the main component (99% or more) of the scallop shell fired powder is hydrated calcium oxide (CaO · nH ₂ O) because there are very few other components except calcium. In addition, it is estimated that this water vapor | steam in ambient air crystallized in the process of natural cooling after baking of a scallop shell powder.

(2) Preparation of a stock solution for deodorization and antibacterial treatment by chelating calcium ion and adjusting the hydrogen ion concentration by solubilization of calcinated shellfish calcium powder and organic acid (Fig. 1, Table 2, Table 3)
As shown in FIG. 1, the organic acid is a carboxylic acid having a carboxyl group (-COOH) such as acetic acid, citric acid, lactic acid and the like, and it easily chelates calcium ion purified from the above-mentioned shell fired powder, ie metal It needs to be complexed.

Among organic acids, citric acid (C ₆ H ₈ O ₇ ) is currently mass-produced industrially by fermenting starch or sugar with Aspergillus niger, a kind of Aspergillus niger, and as an inexpensive and safe food additive There is a demand for Furthermore, there are three carboxyl groups (-COOH) in citric acid, and hydrogen ions (H +) are easily ionized in an aqueous solution having polarity, and the carboxyl groups become carboxylate anions (-COOH-). At this time, it is a molecular orbital method shown in the same FIG. 1 that ionized citric acid (C ₆ H ₅ O ₇ 3-) 2 molecules and a calcium ion (Ca ₂ +) 3 atom form a chelate bond, that is, metal complexation. It confirmed by the optimal structure calculation by (MO).
The chelating nature of the calcium ion remains readily exchangeable with other cations. That is, it means that it is very useful here for chemically bonding with an acidic malodorous substance and for deodorizing.

Scallop shell calcined calcium powder (CaO) (purity: 99% or more, manufactured by Dai-Rishle Co., Ltd.) and citric acid (C ₆ H ₈ O ₇ ) (crystal, purity 100%, manufactured by Sakai Chemical Industry Co., Ltd.) The components of the deodorizing solution (stock solution, 50-fold diluted solution, 500-fold diluted solution) and the antibacterial solution (stock solution, 5-fold diluted solution, 10-fold diluted solution) prepared by adding distilled water to each Show each one.
The mixing ratio of the scallop shell-calcined calcium powder and citric acid in the calcium ion complexing solution is as follows.
Deodorizing solution (stock solution) = Scallop shell calcined calcium powder 20 g / L + citric acid 46 g / L
・ Antibacterial liquid (stock solution) = Scallop shell calcined calcium powder 40 g / L + citric acid 23 g / L
(L means per liter (liter) of distilled water.)

    As shown in Table 2, in the case of the stock solution for deodorization, when the stock solution had pH = 44.1, when it is diluted 50 times with distilled water, the pH becomes neutral with 7.1 and the 500-fold diluted solution But the pH remained neutral at 7.4. In addition, calcium and citric acid, which are highly concentrated in the stock solution, were significantly reduced in 50-fold and 500-fold dilutions to 3% and 2% calcium and 2% in citric acid, respectively, with respect to the stock solution (100%). The reason why the total carbon (TC) is large in the deodorizing stock solution is influenced by carbon (C) derived from citric acid.

    As shown in Table 3, in the case of the stock solution for antibacterials, the scallop shell calcined calcium powder was doubled in comparison with the stock solution for deodorization, and the amount of citric acid was halved, aiming at the control effect of bacteria by high alkalinity. It is a thing. As a result, the pH of the stock solution for antimicrobials was maintained at a strong alkalinity of 11.5, and even with a 5-fold diluted solution of distilled water and a 10-fold diluted solution, the pH could be maintained at 10 or more.

(Operation and effect of Example 1)
The calcium ion complexing solution of the present invention having the above constitution can easily change the mixing ratio of calcium and citric acid and can freely adjust the hydrogen ion concentration (pH) by diluting with water. Accordingly, it is a major feature that an aqueous solution suitable for deodorization and an aqueous solution suitable for antibacterial can be easily produced at low cost. Therefore, the deodorized stock solution and the deodorizing dilution liquid in which calcium ions are complexed using the calcinated shell calcium powder of the present invention and an organic acid and the hydrogen ion concentration (pH) is adjusted, and the stock solution for antibacterials and antibacterials Each dilution can be easily prepared at low cost.

    Scallop shell fired powder has a microscopic structure (molecular crystal structure) of inorganic physical properties different from that of calcite crystal body, and as shown in FIG. 2, a biological origin whose microscopic structure (molecular crystal structure) is vermiculite crystal body It can be said to be calcium carbonate powder, its surface has a fine pore structure (space due to spherical connection), an average pore diameter of about 10 nm, and it has a function to enhance the deodorizing function, and further it is chelated with organic acid Have the property of providing high antimicrobial activity.

(Deodorizing action / effect)
In order to investigate the deodorizing effect of offensive odor gas, ammonia gas (NH ₃ ), hydrogen sulfide (using undiluted solution, 50 times dilution, 500 times dilution solution) consisting of undiluted solution shown in Table 2 are used. Deodorization tests of three types of malodorous gases of H ₂ S) and methyl mercaptan (CH ₄ S, explicit formula CH ₃ SH) were conducted, and the results are shown in Tables 4-1 to 4-3.

    With ammonia gas, the concentration of the stock solution for deodorization became 0 ppm after 10 minutes. Moreover, even with the diluted solution for deodorization (50-fold diluted solution, 500-fold diluted solution), it became 23 to 26 ppm after 10 minutes. The ammonia gas concentration of the stock solution for deodorization becomes 0 ppm, presumably because the neutralization reaction of ammonia by citric acid has occurred. Specifically, citric acid is initially ionized in an aqueous solution to form a metal complex with calcium ions, and citric acid ions have loose ionic bonds (FIG. 1), but ammonium ions are generated when ammonium gas is dissolved in distilled water Since the ammonium ion (electronegativity 3.0) is increased by the electronegativity calcium ion (electronegativity 1.0), it is presumed that the citrate ion is strongly bound by the ammonium ion.

(Antibacterial action / effect)
Tables 5-1 and 5-2 show the antimicrobial effects of E. coli on three types of antimicrobial solutions (diluted solution, 5-fold diluted solution, 10-fold diluted solution) consisting of a stock solution for antimicrobials. Also, the distribution of bacteria in the E. coli test is shown in FIG. 3 to FIG.

According to Table 5-1, E. coli becomes 0% after a long time (0 to 24 o'clock) between the stock solution for antibacterial and the 5-fold diluted solution, and 10% for the 10-fold diluted solution. Even in the target area of distilled water, it showed a 50% decrease after 24 hours. As shown in Table 5-2, in an experiment in which the antibacterial effect was performed in a short time (0 to 6 hours) focusing on the antibacterial effect of the antibacterial stock solution, E. coli was almost killed after 3 hours. The fact that the pH of the stock solution for antimicrobials is strongly alkaline is said to have a great influence. Also from the photographs of FIGS. 3 to 7, colonies of E. coli are not recognized after 24 hours, and it can be said that the antibacterial effect of the stock solution is remarkable.
The calcium ion can be complexed using shell calcinated calcium powder and an organic acid in combination, and the hydrogen ion concentration (pH) can be adjusted to easily produce an antibacterial dilution liquid at low cost.

(Result)
As described above, the deodorizing method using the calcium ion complexing solution of the present invention by the stock solution for deodorizing is capable of achieving the intended purpose uniformly due to its novel constitution, and it is easy to manufacture, and Deodorizing and deodorizing much more quickly compared to the deodorizing and antibacterial technology from the body, the effect can be maintained for a long time, and it is excellent in safety, and it is significantly cheaper and much more economical. It is possible to dramatically improve the workability of production, storage, and utilization, and the difficulty and labor burden of deodorizing and disinfecting work on a large barn and the economic burden thereof. Industry that has been struggling with the size of the industry, and various manufacturing industries that want to reduce the generation of odor gas is solid, rental housing industry and accommodation industry, sales industry, food service industry, retail store sales industry, various service industry , Also been highly evaluated in such fine homes, available across a wide range, it is expected to be those that continue to spread.
