Description

Technology Field

[0001] The present invention relates to a method for manufacturing an odor-reducing agent that utilizes natural extracts to be environmentally friendly and activate indigenous microorganisms. The odor-reducing agent according to the present invention does not contain chlorine-based, strong acid, strong alkaline detergents, or chemicals that are components harmful to crops or the human body, and by including environmentally friendly natural extracts as the main component, it fundamentally eliminates odor substances and does not cause secondary environmental pollution.

[0002] In addition, the present invention is based on an environmentally friendly biological filtration method in which natural extracts, enzymes, oxygen generators, etc. are appropriately mixed into a fermented culture medium mixture, and the microbial group uses odor-causing substances such as ammonia, hydrogen sulfide, and organic matter as nutrients necessary for the generation of material energy and reproduction, thereby decomposing compounds according to the biological metabolic process of microorganisms that decompose odors such as exhaust compounds and converting them into harmless substances for removal. In particular, it removes odors from livestock barns and enables the recycling of by-products and manure generated from livestock barns into functional organic fertilizers. Background Technology

[0003] Recently in Korea, complaints regarding various odors, including livestock odors, have increased by about five times over the past decade, and per capita food waste has increased by 20% over the same period, with the cost of processing it exceeding 1 trillion won annually. Livestock odors, which account for the largest share of odors, also have adverse effects on the human body, such as headaches, drowsiness, and irritation of the eyes, nose, and throat, thereby lowering the quality of life for the public.

[0004] Furthermore, livestock odor control measures are limited to specific areas, such as single workplaces or particular complexes, resulting in inadequate overall odor management. Consequently, the majority of residents are complaining of suffering caused by the odor, particularly during the summer, on cloudy days, and during commuting hours.

[0005] While the causes of livestock odor are diverse, the permissible emission standards under the Odor Prevention Act apply only to emission outlets and site boundaries, causing numerous problems. Furthermore, stakeholders including livestock farmers, local residents, and administrative agencies hold differing views on livestock odor, and difficulties are being encountered in resolving the issue due to these differences in opinion.

[0006] As mentioned above, due to the severity of the odor problem, various solution providers have applied methods utilizing sealing and capture, absorption and adsorption, combustion, ozone oxidation, and UV and plasma treatment to farms with severe odors. However, they have not seen proper practical effects, and even if facilities are installed with government support, the problem has not been fundamentally resolved due to high operating costs, increased burden on farmers, and low efficiency of the methods. Recently, as the most effective method to solve this problem, eco-friendly methods utilizing microorganisms, which are relatively inexpensive and highly effective compared to other methods, are being used most frequently.

[0007] However, even in the aforementioned methods utilizing microorganisms, the nature of microorganisms makes them sensitive to external environmental factors (temperature, humidity, etc.), making it difficult for them to adapt to new environments. Furthermore, existing microbial odor reducers have limitations in that indicators of efficacy and effectiveness are mostly measured under laboratory conditions, resulting in actual effects differing from the indicators. Additionally, because it is difficult to maintain microorganisms in a viable state during the actual product manufacturing process, most products containing microorganisms simply indicate the raw material content. Moreover, the use of microorganisms involves varying safety and risk depending on the application method, requires a significant amount of time, and necessitates proper use and management.

[0008] Korean Published Patent 10-2011-0040394 (April 20, 2011) Korean Registered Patent 10-0847905 (July 16, 2008) The problem to be solved

[0009] The main objective of the present invention is to provide a method for manufacturing an eco-friendly odor-reducing agent utilizing natural extracts to eliminate the main odor substances NH3, H2S, and CH3SH by activating beneficial fermentation bacteria to address the aforementioned problem of odor removal, establishing a microbial ecosystem using an accelerator to create an environment that kills putrefactive bacteria—the main cause of odor generation—at high temperatures, and providing carbon and other elements necessary for microbial proliferation, thereby providing a microbial habitat resulting from the modification of the organic structure of additive components. means of solving the problem

[0010] To achieve the above objective, the present invention is characterized by the process of extracting a peat extract by filtering a mixture in which peat is added to a metal hydroxide (MOH) and stirred at 30°C to 40°C for 2 to 3 hours, and then a mixture in which a weak acid, a porous material, and a metal chloride are added and stirred again for about 2 hours; the process of producing a condensate by condensing the steam generated during the thermal decomposition of wood; and the process of mixing the peat extract and the thermal decomposition product with a fermentation liquid containing a natural organic acid, adding a buffer solution mixed with a weak acid (AH) and a weak salt (AM) to the resulting mixture, and then filtering the suspended solids. Effects of the invention

[0011] The present invention has the effect of recyclable organic fertilizers or functional liquid fertilizers by fermenting organic matter to treat by-products or manure generated in livestock barns. It is not only eco-friendly because it does not contain chlorine-based, strong acid, strong alkaline detergents, or chemicals that cause damage to crops or are harmful to the human body, but also has the effect of fundamentally removing odor substances and not causing secondary environmental pollution by including an eco-friendly pure plant-based natural extract as the main component.

[0012] FIG. 1 is a diagram of an odor reduction method through the injection of an odor-reducing agent (AC BOSTER (AC-B)) according to the present invention. Figure 2 is a manufacturing process diagram of the odor-reducing agent (AC BOSTER (AC-B)) of the present invention. Figure 3 is a diagram of the natural extract manufacturing method of the present invention. Specific details for implementing the invention

[0013] Hereinafter, a method for manufacturing an eco-friendly odor-reducing agent containing a natural extract according to the present invention will be described in detail.

[0014] First, in the present invention, the odor-reducing agent manufacturing step proceeds mainly through a first extraction step (S100), a second extraction step (S200), a mixing step (S300), and a filtration step (S400).

[0015] The first extraction step (S100) includes a first stirring step (S110) in which a mixture of peat added to a metal hydroxide (MOH) is stirred at 40±10℃ for more than 1 hour, and a filtration step (S120) in which a mixture of a weak acid, a porous material, and a metal chloride is added and stirred again for more than 1 hour is filtered to extract the peat extract. In the present invention, a mixture of peat added to a metal hydroxide (MOH) is stirred at 30~40℃ for 2~3 hours, and a mixture of a weak acid, a porous material, and a metal chloride is added and stirred again for about 2 hours is filtered.

[0016] The addition of a weak acid in the first extraction step is intended to solidify components unnecessary for extracting the peat extract and improve the quality of the extract, and the addition of a porous material is intended to adsorb fine suspended matter contained in the mixture stirred in the first stirring step (S110) to improve filtration performance in the filtration step (S120).

[0017] The second stirring step (S130) is a step of adding and stirring a metal chloride, and is performed for the purpose of improving filtration by inducing the aggregation of suspended matter that is not adsorbed by the porous material in the mixture stirred in the first stirring step (S110).

[0018] The second extraction step (S200) includes a pyrolysis step (S210) for pyrolyzing wood, a cooling step (S220) for condensing water vapor generated during pyrolysis to produce a condensate, and a separation step (S230) for separating the pyrolysis product from the condensate to obtain the pyrolysis product. At this time, the separation process is carried out in three stages over a long period of time, and only the liquid from the middle layer among the three stages is extracted and used. A separation activator may be added to shorten the time of the long separation process. In addition, it is desirable to undergo a distillation process to improve the quality of the separated material. A detailed description of the extraction of the pyrolysis product is omitted as it is identical to the method of extracting the pyrolysis product above.

[0019] The mixing step (S300) mixes the peat extract and the pyrolysis product with a fermentation liquid containing natural organic acids to produce a mixture. The stability of the solution can be improved by adding a buffer solution mixed with a weak acid (AH) and a salt of the weak acid (AM) to the mixture produced in the mixing step (S300).

[0020] In addition, in the filtration step (S400), the mixture mixed in the mixing step (S300) is filtered to remove foreign substances such as floating matter once again, thereby enabling the production of a high-quality odor-reducing agent that can prevent nozzle clogging when the odor-preventing agent is sprayed and used.

[0022] According to the technical configuration above, the fermented liquid extracted from natural materials not only has a unique antibacterial effect but also prevents the oxidation of iron by the antioxidants generated during the fermentation process, thereby stabilizing the aqueous ferrous sulfate solution. When the odor-reducing agent, which is a mixture of the aqueous ferrous sulfate solution, the fermented liquid, and the fragrance liquid, is sprayed onto livestock barns or odor-causing substances in a stabilized state, it is possible to remove pollutants due to the deodorizing effect of the ferrous sulfate, the antibacterial properties of the fermented liquid, and the fragrance properties of the fragrance liquid.

[0024] In addition, 0.1 to 1 gram of fragrance liquid may be added based on 100 grams of aqueous ferrous sulfate solution. This is to vary the amount of fragrance liquid added depending on the application of the deodorizer. For example, when the odor-reducing agent (AC BOSTER (AC-B)) of the present invention is used in a bathroom or kitchen, the fragrance can be increased to create a pleasant environment through a good scent in addition to deodorization and antibacterial properties, and when used on compost or livestock, the fragrance can be set to be somewhat lower.

[0025] Meanwhile, the odor-reducing agent (AC BOSTER (AC-B)) manufactured according to the present invention is preferably used by diluting it 10 to 1000 times depending on the purpose or conditions of use, and not only can it rapidly deodorize odor components generated in livestock facilities, but also exhibits effective effects in sterilizing bacteria or viruses and controlling pests due to its antibacterial properties.

[0026] In addition, the odor-reducing agent (AC BOSTER (AC-B)) manufactured according to the present invention can produce functional liquid fertilizer or functional organic fertilizer by reusing by-products or manure generated in livestock barns through the fermentation of organic matter.
