The present invention relates to a method of reducing odor and promoting maturation of livestock manure and liquid fertilizer tanks using an alkali composition composed of carry, borax and probiotic.

As the livestock industry became full-time and industrialized, the proper treatment of livestock manure became a heavy issue.

If the manure that occurs every day, such as milk or left alone, serious air pollution, water quality and soil pollution problems have recently been studied in various ways to cleanse or organic fertilizers, and various types of facilities are distributed to livestock farms There is a situation.

However, there are various problems from the perspective of domestic livestock farmers, depending on the method, the financial burden is too high, requires professional management skills, or depending on the limitations of the equipment.

In other words, microbial agents that reduce the odor of livestock manure have a natural-friendly advantage, but due to the many disinfectants used to prevent livestock diseases, they are not functioning. In particular, the external temperature is below 10 ° C. In the fermentation function due to the growth of microorganisms is suspended, there is a disadvantage that the range of use is reduced to seasonal factors.

In addition, general chemicals are not affected seasonally, but because the unit price is high, there is a disadvantage that the processing cost is high.

Accordingly, the present applicant is inexpensive and easy to handle in domestic livestock farms that have to be intensively reared in a narrow country, and can be applied to livestock manure and processing equipment to reduce odors and to prepare manure more quickly. To develop a composition that can shorten the period of liquefaction and to provide a method for treating livestock manure using the composition.

Accordingly, the present applicant has completed the present invention using a microbial agent treatment method for the chemical acid composition mainly chemicals used as feed additives and the alkaline composition of the applicant (patent No. 0254037).

The present invention has been made to recognize and improve the problems of the prior art as described above, the object of the present invention is a mineral acid composition consisting of iron sulfate, aluminum sulfate and iron chloride and potassium silicate potassium carbonate, potassium citrate, sulfuric acid The present invention provides a method for reducing odor and promoting housing in livestock manure and livestock manure liquid tank by using an alkali composition comprising a microorganism preparation for carry and borax.

In order to achieve the above object, the present invention is (I) 200 to 400g of iron sulfate, 100 to 400g of aluminum sulfate and 50 to 150g of ferric chloride with respect to the total weight of 1,000g dissolved in water and ( II) 300 to 500 parts by weight of a composition in which 50 to 70 g of potassium silicate, 60 to 70 g of potassium carbonate, 20 to 40 g of potassium citrate, 5 to 10 g of sulfuric acid, and 20 to 40 g of borax are dissolved in water. 500 to 700 parts by weight of livestock manure composition consisting of 500 to 700 parts by weight and 0.1 to 0.2 parts by weight of probiotic and (III) potassium silicate 50 to 70 g, potassium carbonate 60 to 70 g, potassium citrate 20 to 40 g, and 5 to 10 g of sulfate And it provides a composition for treating livestock manure consisting of 300 to 500 parts by weight of a composition in which 20 to 40 g of borax is dissolved in water, 500 to 700 parts by weight of excipients and 0.1 to 0.2 parts by weight of probiotics.

Moreover, in order to achieve another objective, this invention provides the method of processing the composition of said (I) to livestock manure, and reducing the bad smell of livestock manure.

In addition, in order to achieve another object, the present invention is the first treatment of the composition of the (I) or (II) to livestock manure or livestock manure slurry and the composition of the (III) the first treated livestock manure or Provided is a method for reducing odor and promoting housing in a livestock manure and livestock manure liquefaction tank comprising secondary treatment to a livestock manure slurry.

As the solid excipient of the composition (II) used in the present invention, it is preferable to use activated carbon, zeolite or biotite, and the composition is molded into a shape that is easy to use, and then a dry solid block is formed. use.

In addition, the excipient of the composition (III) is preferably water or a solid powder composed of zeolite and biotite in a ratio of 2: 3, and water is used as a solution, and zeolite and biotite are used. It is molded into an easy-to-use shape and then formulated into a dry block.

At this time, the block (solid agent) prepared as described above is preferably used in a large liquid ratio tank, because the block is gradually melting while acting. However, if you want to act quickly, it is preferable to use a liquid.

In addition, since biotite in the said excipient contains a large amount of germanium, it can emit a large amount of far infrared rays, and its component is used for reducing odor gas, such as ammonia gas.

In addition, the probiotic of the composition (III) is preferably Saccharomyces cerevisiae yeast and Bacillus subtilis Bacillus, wherein the concentration of the probiotic is (III) composition It is preferable to use 0.1 parts by weight of Saccharomyces cerevisiae at 5.0 × 10 ⁹ cfu / g and 0.001 parts by weight of Bacillus subtilis at 5.0 × 10 ¹¹ cfu / g.

In addition, when directly used in a barn operated by a farmhouse, the composition (I) of the present invention may be used alone, since the farmhouse does not prefer a treatment method that goes through several steps, and a lot of disinfectants are used (III). It is because it is more preferable not to use the composition of).

Hereinafter, the present invention will be described in detail.

In the method of reducing the odor of the livestock waste and liquid fermentation tank of the present invention and promotes the ripening, the composition (I) is non-toxic as a flocculant, iron side effects (FeSO ₄ ), aluminum sulfate <Al ₂ (SO ₄ ) ₃ >, these materials act under acidic conditions.

In this case, ferrous chloride is used to reduce hydrogen sulfide and to suppress it because the livestock manure becomes too strong when only iron sulfate is used.

Aluminum sulfate, also called alum or alumina sulfate, is used extensively because of its excellent cohesive properties, inexpensive, non-toxic, suitable for all water haze and ease of handling.

Ferrous sulfate (FeSO ₄ · 7H ₂ O) is pale green with iron ions (Fe ²⁺ ), and because it has a high solubility, it is almost incapable of use in aqueous solution, but precipitates at pH7.7 or above.

The chemicals are neutralized by the working principle of the following Chemical Formulas 1 and 2 to neutralize ammonia (NH ₃ ) and hydrogen sulfide (H ₂ S), which generally give off odors of livestock or pigs.

[Formula 1]

2NH ₄ ⁺ + SO ₄ ^2- → (NH ₄ ) ₂ SO ₄ ↓

[Formula 2]

H ₂ S + Fe ²⁺ → FeS ↓

In the composition of the present invention, the ferrous sulfate is limited to 20 to 40% and the ferric chloride is adjusted to 5 to 15% in the component content of the composition (I) to prevent the acid from becoming strong when only ferrous sulfate is used. 25 to 55% of these components are combined, and the effect is insufficient when the amount is less than 25% in proportion to the amount of hydrogen sulfide gas and ammonia gas generated from feces. This is because minerals are precipitated. The reason is that the content of aluminum sulfate is set to 10 to 40%.

The composition (II) is a composition having the same principle as the composition (I), wherein the liquid formulation is used as a solid agent. However, an excipient is used instead of water without using ferric chloride. This is because the solid agent does not need to be used since it does not suddenly acidify using an aqueous solution because it reacts slowly with the livestock manure.

At this time, the excipient (賦形劑) refers to a substance to make the formulation in any shape or increase the amount, in the present invention is used to make the form of the composition in an aqueous solution or solid state.

Accordingly, in the present invention, an excipient of solid powder having adsorptive properties such as active carbon, zeolite, biotite, etc. is used, and these substances have adsorption and purification effects of harmful substances such as heavy metals.

In addition, the (III) composition of the present invention is a Korean patent (10-0254037) already developed by the present inventors, the original purpose is a strong alkaline aqueous solution composition based on potassium to improve acidified water quality or soil In the present invention, the use of the same, in the method of reducing the odor of the livestock manure and livestock manure liquid tank and promote the ripening, neutralize the acidification conditions due to the primary treatment with strong alkaline far infrared rays, activation of microbial agents It creates a surrounding environment (pH 6.5-7.0) to promote fermentation and maturation. Here, the pH of the slurry of the treated livestock manure is adjusted to 6.5 to 7.0 after one day after the secondary treatment.

Here, the composition (I) and (II) of the present invention, in which the ferrous sulfate and aluminum sulfate are the main components, are precipitated with ammonia sulfate and iron sulfide, as shown in Chemical Formulas 1 and 2, and the acidic conditions are obtained. Strongly alkaline aqueous solution neutralizes the pH and adjusts the pH, which plays a role in maintaining the optimal environment of the microorganism that promotes later ripening. In addition, the use of 30 to 40% of the strong alkaline aqueous solution on the basis of 1,000 parts by weight excluding the probiotic is less than 30% of the neutralization effect is insufficient, if the 40% or more excess precipitate is generated.

In addition, zeolite and biotite are used as solid phase excipients, and zeolite is used with low turbidity aluminum sulfate to provide a nucleus for adsorption of colloidal particles in alkaline clay, and has a significant coagulation aid, and biotite emits far infrared rays. To increase.

In addition, in the present invention, the probiotic agent is not deteriorated in activity by the disinfectant used for disease prevention in the barn or pig house, and the spores so as not to be affected by the season to stop the function of fermentation by viable growth under below 10 ℃ Spore forming bacteria Saccharomyces cerevisiae and Bacillus subtilis are preferred.

In addition, the amount of probiotics used is about 5 million Saccharomyces cerevisiae and about 50 million Bacillus subtilis per gram of the composition used in the treatment step (ii). This is because around 5 million or 50 million pieces have a good effect on the bacterial survival rate.

Therefore, Saccharomyces cerevisiae 5.0 × 10 ⁹ cfu / g is used as 0.1 parts by weight and 0.001 weight of Bacillus subtilis 5.0 × 10 ¹¹ cfu / g to the weight of the composition used in the step (ii). It can be used as wealth.
