Livestock excretion decomposing agent fermented with effective microorganism and manufacturing method

The present invention relates to a livestock manure degrading agent fermented with beneficial microorganisms used as a litter on the bottom of a barn and a method for producing the same, and more particularly, a composition in which natural sawdust (songbun), rice bran (rice bran) and molasses are mixed with each other. It is possible to drastically reduce livestock wastewater by inhibiting the generation of harmful gases, prevent disease by using livestock manure decomposer prepared as fermentation by injecting beneficial microorganisms into fermentation and fermenting them as litter. The present invention relates to a livestock manure fermentation agent and a method of manufacturing the same, which can open a bright future for agricultural and livestock farmers.

In Korea, the rapid industrialization of agricultural society has raised awareness of environmental conservation, and in the 1980s, the rapid increase in the number of farms per house led to environmental pollution caused by livestock manure, especially water pollution. The regulation of large-scale livestock facilities was regulated by small and medium sized livestock facilities in 1987 under the "Waste Management Act", and from 1992, the enactment rule on the treatment of sewage, manure and livestock wastewater came into force. In 1994, the number of permits was enlarged for the second time, and the water quality standards for discharge were also greatly strengthened.

By the way, the treatment method of livestock manure can be roughly divided into a storage liquid fertilization method, a landfill disposal method, a composting method, a soil infiltration method, a spraying water method as shown in Figs. Since the composting method does not require a large amount of farmland regardless of the size of livestock raising, it is considered to be a relatively suitable method for Korea with a narrow land area.

The composting method is also a method of fermenting livestock manure with a moisture control agent (mainly sawdust, chaff etc.) and livestock manure, and filling the bottom of the barn with a moisture control agent (sawdust) to a certain depth, and then raising livestock on the top of sawdust. There is a method of fermenting sawdust and manure by spraying the agent, the latter is commonly referred to as sawdust fermentation barn.

In Korea, in the early 1980s, some companies introduced pig breeding methods for fermenting sawdust fermented in pig farms and breeders in Gangwon-do.However, since the filling of sawdust was reduced to about 30cm, it was not widely distributed due to problems in winter breeding at low temperatures. In the test site, the depth of filling of sawdust was deepened to 60-100cm, which solved the problem of manure treatment even in winter breeding, and it has been spreading all over the country. Many sawdust fermented pigs are being converted into general pigs due to problems such as respiratory disease in winter due to harmful gases and deterioration of summer productivity due to high temperature in breeding season when fermentation of sawdust and manure during high temperature in summer.

On the other hand, in farming and livestock farming, livestock manure was a valuable reclaimed material that was not tolerated. However, full-time livestock farming separated from farming is a source of income depending on the processing method and level or social conditions. Operational costs are high, and untreated livestock manure cannot be used immediately as fertilizer because crops are ill due to the generation of gas, etc., especially at the present time in front of the opening of livestock products, There is an urgent need for resourceization.

 The present invention has been invented as a result of repeated studies to improve the problems with the well-known sawdust fermentation house, the main purpose is to provide a livestock manure degrading agent for powdery litter that can significantly reduce the excrement excreted by livestock have.

Another object is to provide livestock manure digesters for litter, which can minimize odor, raise livestock in a pleasant environment, prevent disease and shorten the breeding period and increase the income of livestock farmers.

Another object is to provide livestock manure decomposers for powdery litter, which can be harmless to crops and realize eco-friendly organic farming, even if the manure decomposed from the bottom of the barn is immediately sprayed on rice fields or fields.

In order to achieve the above object, the present invention is ① by mixing 60 ~ 80% natural sawdust and 20-40% of rice bran (rice bran) in a weight ratio and add 5-10% molasses of the total weight to it to make a composition by stirring together process;

② diluting the beneficial microorganisms to 5 × 10 ⁹ CFU / mL of the beneficial microorganisms in the stirring composition and injecting 5 to 10% of the total weight thereto to maintain the water content of 40 to 50%;

③ The livestock manure prepared by fermenting the composition in which the microorganisms are injected is fermented at 25 to 30 ° C. for 8 to 12 hours and aged at 35 to 40% for 50 to 80 hours to maintain the final moisture content of 30% or less. A method for preparing a fermentation agent is provided.

In addition, in order to achieve the above object, the microorganisms used in the production method of the present invention are Lactobacillus asidophilus, Bacillus subtilis, Aspergillus niga, Saccharomyces cerevisiae, Pseudomonas genus , Genus Nitrosomonas, photosynthetic microorganisms are provided.

In addition, in order to achieve the above object, there is provided a livestock manure decomposing agent powdered fermented with a microorganism completed by the production method of the present invention.

In addition, in order to achieve the above object, a livestock manure decomposing agent completed by the production method of the present invention is filled with a depth of 5 ~ 15cm at the bottom of the barn and a method for raising livestock on the upper surface.

As a result of using the powdered livestock manure degrading agent prepared by the present invention as a litter on the bottom of the barn, the experimental group produced little manure discharge compared to the control group, and carbon dioxide, ammonia, and hydrogen sulfide, which cause odors, were significantly lower. Breeding days were significantly reduced, respiratory disease and diarrhea did not occur. The difference is that the production of various alcohols produced during fermentation of organic matter and pine ash by the added beneficial microorganisms accelerated the evaporation of water, and in particular, the organic acid produced by fermentation microorganisms suppressed the growth of decaying microorganisms contaminated with feces. While suppressing the formation of odors, it has the effect of maintaining the growth of microorganisms that ferment organic matters, thereby suppressing the diseases frequently occur in pig breeding, and the concentration of ammonia, which occurs most frequently during the decomposition of livestock manure, Compared to almost no increase in odor generation, the decomposed manure can be composted immediately, and eco-friendly organic farming can be realized.

In order to solve the problems of the conventional sawdust fermentation barn, the present invention, rice bran (branch) and molasses in the sawdust and seven microorganisms of Lactobacillus acidopillus (Bacillus subtilis), Bacillus subtilis ), Aspergillus niger, Saccharomyces cerevisiae, Pseudomonas, Nitrosomonas, Phototrophic bacteria The fermentation, maturation, and livestock manure decomposer produced by maintaining a predetermined moisture was applied to the litter of the bottom of the barn, and the rapid disappearance of livestock manure and further harmful gases generated during decomposition of manure, namely ammonia and hydrogen sulfide Minimize generation of carbon monoxide, carbon monoxide, carbon dioxide, etc. DETAILED DESCRIPTION The embodiments of the invention serves to realize as follows.

Sawdust is a powder that is swept out of wood when it is turned or cut into saws. Natural sawdust is mainly used. Non-chemical sawdust can be used, and most of it is used as barn floor litter or compost.

Rice bran is a pulverized mixture of skin, seedlings, and lamellae that occurs when the brown rice is milled to make white rice. In chemical composition, water 13.5%, protein 13.2%, fat 18.3%, sugar 38.3%, fiber 7.8%, ash 8.9%. Vitamin B ₁ contains 2.5mg of 100g and most of them contain vitamin E. Used as feed or fertilizer.

Molasses is a by-product of making sucrose, which includes waste molasses that is not edible in a broad sense. However, in a narrow sense, it refers to the honey that is produced when the crude sugar is refined or when the ice sugar is made. Molasses is a pale yellow, transparent, viscous sugar solution. The molasses used in agriculture is a liquid substance with a high viscosity with a sugar content of 50-60% and a specific gravity of about 1.39. It is mainly used as a carbon source in fermentation of various raw materials.

Microorganisms used in the present invention include Lactobacillus asidophilus, Bacillus subtilis, Aspergillus niga, Saccharomyces cerevisiae, Pseudomonas, Nitrosomonas, and photosynthetic microorganisms.
