Description

{Method of fertilizing Animal Corpse}

The present invention relates to a method for fertilizing an animal carcass, and more particularly, to an animal carcass fertilization method for rapidly and safely decomposing carcass of an animal slaughtered or killed by a disease, as well as by- Fertilizing method.

For livestock carcasses that have been killed or suspected of being infected with livestock infections, each country treats them in a way that is appropriate for their environment, mainly anaerobic digestion, rendering, composting, , Burial, alkaline hydrolysis, lactic acid fermentation, nontraditional technologies, and the like.

In Korea, livestock carcasses are rapidly incinerated and buried according to Livestock Infectious Diseases Prevention Law. However, in Korea, mainly burial treatment methods are mainly used.

The amount of livestock carcasses that must be buried by the livestock epidemic that occurs each year can be further increased in the future, so the buried area is bound to expand. Therefore, when the livestock carcasses buried in the livestock epidemic are buried, the burial method and insufficient consideration of the environmental factors are causing harm to the second environment such as odor and soil and groundwater pollution. .

In general, when buried in the ground, the carcass degradation rate is much slower due to the lack of air circulation than when it is left outside the ground. If the degradation proceeds slowly, the odor and gas will continue to be generated Thereby causing contamination of the environment.

In the case of burnt lime used for burial of livestock livestock, it is mainly used for the purpose of bactericidal action, but it not only hinders the decomposition rate of the carcass, but also changes the soil in the buried area to strongly alkaline, The microorganisms of the microorganisms are killed and a large amount of odor and leachate are generated.

In order to solve the above-mentioned problems, Korean Registered Utility Model No. 20-0437996 (Nov. 11, 2008) discloses a livestock carcass processing site.

According to the livestock carcass processing apparatus, the livestock carcass is first treated with a chemical treating agent such as an acid or a base, and the product obtained therefrom is post-treated. However, the treatment process is simple and the treatment cost is low. (PH) of the decomposed liquid by-products is strongly acidic or strongly alkaline, disposal of the decomposed liquid by-products is not easy.

Conventionally, a livestock carcass that is disposed of as a livestock infectious disease such as AI (avian influenza) or foot-and-mouth disease is buried, and there is a problem that a lot of odor and leachate occur during burial treatment.

The present invention is characterized in that not only malodor and leachate are generated, but also rapidly and safely disassemble the livestock carcasses that have been disinfected with a large amount of infectious diseases, and the by-products obtained in the disintegration process can be recycled as fertilizer in an environmentally friendly manner.

In the present invention, an animal carcass means a livestock carcass such as a chicken, a duck, a pig, a cattle, and the like, which has been killed by a livestock infectious disease such as AI (avian flu) and foot and mouth disease.

First, a method for fertilizing an animal carcass according to the present invention will be described.

The method for fertilizing an animal carcass according to the present invention comprises:

A step of preparing a powder treating agent and a liquid treating agent (step 1);

Adding the powder treating agent and the liquid treating agent to the animal carcass and stirring (step 2); And

Humidifying the agitated material (step 3);

.

In the step 1, the powder treating agent includes 50 to 80% by weight of at least one selected from sawdust or puffy rice, 10 to 40% by weight of peat, 1 to 8% by weight of elvan, and 0.5 to 3% by weight of microorganism.

The powder treating agent of the present invention plays a role of inhibiting the generation of odor and leachate in the composting process of an animal carcass and decomposing proteins of animal carcasses.

If less than 50% by weight of the selected one of the sawdust or swollen wax is contained, the function of absorbing moisture is insufficient and the function of smoothly supporting the microbial activity is insufficient. If the amount exceeds 80% by weight, There are fewer problems involved.

If the peat is contained in an amount of less than 10% by weight, the function of assisting the fermentation of microorganisms is insufficient, so that it takes a long time for the carcass to compost. When the peat exceeds 40% by weight, other compositions are not included.

If the elvan stones are contained in an amount less than 1% by weight, there is a problem that the deodorizing function is insufficient. When the elvan stones are contained in an amount exceeding 8% by weight, other compositions are not included.

If the microorganism is contained in an amount of less than 0.5% by weight, there is a problem that the time required for composting the animal body takes a long time. If the microorganism is contained in an amount exceeding 3% by weight,

The sawdust used in the present invention may be those prepared by slicing the wood thinly, and the kind of the wood is not particularly limited. The sawdust preferably has a particle size of 5 to 15 mm. When the particle size is less than 5 mm, the sawdust is completely decomposed by microorganisms during fermentation. When the particle size exceeds 15 mm, The fermentation time becomes too long, and the texture of the sawdust may become too coarse. The sawdust preferably maintains a water content of 25 to 35%.

The swollen rice husk means that the tissue is softened by processing the rice husk at high temperature and high pressure by expanding the general rice husk at a high temperature and a high pressure. Through such processing, the water absorption ability is remarkably increased and the polarity is improved and the moisture content is easily controlled have.

The general rice husk can be processed at a high temperature of 250 to 320 DEG C and a high pressure of 600 to 700 Kg / cm < 2 > for 5 seconds to 10 seconds in order to process the rice husk into swollen rice husks. If it exceeds the above range, the rice husk may excessively swell and burn, and if it is less than the above range, the swelling may not be performed properly.

The above-mentioned peat is a peat, a reed, a forage and other plants and plants, pine trees, birch trees, etc., fluid of the body is deposited on the basin in the presence of water in the presence of biochemical changes such as fungi, . Peat is broadly included in one type of coal but is generally distinct from coal. Unlike peat, which is buried underground like coal, lignin and cellulose, which are the main constituents of plants, are mainly decomposed in the surface (unlike the case where woody matter is produced by undergoing earth pressure and geothermal action Peatification). The peat of the present invention contains all kinds of peat, although there are differences in the kind of original plant material and degree of decomposition. Some examples of peat are tundra peat, grass charcoal, woody peat, and peat peat, especially sphagnum peat moss (Canadian peat, Bion Peat) have. Peat is adsorbing phenolic compounds, organic compounds and heavy metals. Preferable examples of the phenol include cresol, xylenol and phenol. Preferable organic compounds are polycyclic aromatic hydrocarbons (PAHs) such as naphthalene, fenaphthalene, pyrene and phenanthrene. Examples of the heavy metals include Cd, Zn, Pb , Ni, Cu or Co is preferable.

The elvan stone contains 45 kinds of minerals such as ferric oxide and calcium, magnesium, germanium, and selenium with anhydrous silicic acid and aluminum oxide as main components, and 30,000 porous neutral bodies per 1 cubic meter of elvan. It has proven its ability to remove heavy metals such as Pb and Cd, and has the ability to absorb odorous substances and to deodorize harmful substances. have.

It is preferable that the microorganism uses an anaerobic microorganism.

In the step 1, the liquid treatment agent comprises 60 to 80% by weight of water, 3 to 8% by weight of Bacillus subtilis, 3 to 8% by weight of Bacillus bacteria, 3 to 8% by weight of photosynthetic bacteria, 3 to 8% by weight of lactic acid bacteria, %.

The Bacillus subtilis is a kind of aerobic bacteria and has no toxicity and is a spore-forming bacterium widely distributed in nature such as dried grass, soil, sewage and air. The cell has a number of flagella around it in the shape of a short stick, making a large colonization of grayish white. It is characterized by high productivity of enzymes such as cellulase, amylase, protease, and xylanase, which are highly heat resistant and useful for livestock. .

The bacterium is preferably selected from the group consisting of Lactobacillus lactis, Lactobacillus luteri, Lactobacillus bulgaricus, Lactobacillus brevis, Lactobacillus salivarius, Lactobacillus acidophilus, Lactobacillus carcase, Lactobacillus cabatus, Lactobacillus fermentum, And at least one selected from the group consisting of Bacillus subtilis, Bacillus plantarum, Lactobacillus helveticus, Bacillus lentus, Bacillus ricinifomis, Bacillus subtilis, Bacillus cereus, Bacillus coagulans, Bacillus polyphenthumus and Bacillus pililus Can be used.

The photosynthetic bacterium belongs to an inorganic nutrient (or an autotrophic bacterium) capable of synthesizing organic nutrients required for development from the inorganic matter of the environment. The bacterium uses the photovoltaic energy as an energy source and the CO ₂ as a carbon source. Under anaerobic and semi-anaerobic conditions, ATP is formed by photosynthesis in three balanced photosynthetic cyclic electron transport systems, and carbonic acid is fixed by using simple organic matter or hydrogen reduction power, and it is effective to remove odors and to suppress gas in farms and farms .

The lactic acid bacteria are one of the most beneficial microorganisms available to human beings and widely distributed in natural environments such as digestive tracts of mammals, various fermented foods and soils. The various organic acids (lactic acid, acetic acid, and benzoic acid) produced by these lactic acid bacteria can acidify the intestinal pH to neutralize the pathogenic bacteria, restore the intestinal flora balance to normal, and prevent diarrhea and enteritis. In addition, hydrogen peroxide produced by lactic acid bacteria kills pathogens by strong oxidative action and destruction of protein structure, and bacteriocin, an antibiotic produced by lactic acid bacteria, inhibits the growth of bacteria producing decay products. Therefore, lactic acid bacteria maintain the normal flora in the intestines and inhibit the microorganisms in the hospital. Especially, it prevents the enteritis and the hari, and has the effect of improving the animal growth rate and the feed efficiency. Wherein the lactic acid bacteria are selected from the group consisting of Bifidobacterium longum, Bifidobacterium bifidum, Bifidobacterium semifilum, Bifidobacterium phosphate, Enterococcus lactis, Enterococcus thermophilus, Enterococcus faecium, And at least one selected from the group consisting of Pseudomonas sp., Bacterium, Pediococcus selegivia, and Pediococcus acidiflucis.
