Description

Structure of the burial site of our livestock {PERISH LIVESTOCK BURIAL GROUND STRUCTURE}

The present invention relates to a burial site structure for dead livestock for preventing the spread of secondary environmental damage caused by leachate while burying dead livestock in the ground during culling to prevent the spread of infection during an outbreak of foot-and-mouth disease or avian influenza.

In general, foot-and-mouth disease is a viral acute livestock infectious disease that occurs in animals such as cows, pigs, sheep, deer, and goats with split hooves. Blisters form on the mucous membrane of the mouth or the skin between the claws, and the body temperature rises rapidly. It is a contagious disease showing symptoms of rising and decreased appetite, and it is designated as Korea's first type of livestock infection along with highly pathogenic poultry influenza.

When an infectious disease caused by foot-and-mouth disease, which is the first kind of livestock infectious disease, highly pathogenic poultry influenza, cattle disease, bovine lung disease, nasal stenosis, poultry cholera, poultry paste, etc. occurs, the rapid spread of infectious diseases occurs In order to prevent this, the culling method is mainly used by slaughtering and burying by the area where it occurs, and the method of burying livestock for slaughter includes trench burial, landfill, and mass burial by designated area. is being used

In the above-described culling and burial method, trench burial is a method of digging a ditch with a relatively small burial and burying livestock carcasses side by side therein. It is difficult to select a site, has a high potential for environmental harm, and has disadvantages in that it cannot be recycled after treatment.

In addition, the pit burial (landfill) is a medium-scale burial, which is a method of stacking and burying a certain amount of livestock carcasses. Therefore, it is difficult to identify the mechanism of action, and there is a disadvantage that there is a risk of secondary foot-and-mouth disease damage due to a transport accident.

And the mass burial designated by the zone designation is a method of burial processing by designating a certain area as a carcass disposal site for livestock as a large-scale burial. However, there are disadvantages in that agreement with local residents is required for site selection, large-scale continuous monitoring of a wide area is required, and a separate establishment of a treatment plan for buried areas is required after stabilization.

Currently, domestic livestock burial-related rules and guidelines include burial standards according to the Enforcement Regulations of the Livestock Infectious Diseases Prevention Act, poultry influenza, foot-and-mouth disease, infectious spongiform encephalopathy, emergency action guidelines, and follow-up management of burial wells using trace materials according to the Groundwater Act.

Hereinafter, the configuration and operation of the present invention will be described in more detail based on the accompanying drawings. In describing the present invention, the terms or words used in the present specification and claims are based on the principle that the inventor can appropriately define the concept of the term in order to best describe his invention. It must be interpreted as a meaning and concept consistent with the technical idea of

The structure (1) of the present invention is a buried space (2) excavated underground as shown in FIG. 1; a filter media layer (3) formed by filling the lower end of the buried space (2) with a filter media containing earth and bentonite; and a buried layer (4) formed by laminating waste yarn on the filter media layer (3): a buried layer (5) formed by laminating soil and sand on the buried layer (4).

The buried space 2 is a space formed through excavation in the ground, and although not shown in the drawings, an impermeable sheet should be applied to the inner periphery after excavation to control external outflow of leachate, etc.

A filter media layer 3 is formed at the lowermost end of the buried space 2, and the filter media layer 3 is formed by filling a filter media containing earth and bentonite, and the decay and decomposition process of dead cattle by bentonite. to adsorb the leachate generated from The bentonite expands by the action of the bentonite, and by this expansion, the filter media layer 3 forms a tight paste. That is, when cracks occur in the filter media layer 3 due to drying shrinkage, etc., these cracks can act as a lowering point of structural integrity. Bentonite is incorporated into the filter media layer 3 to control this problem.

The buried layer 4 is a configuration in which the dead dead livestock is laminated on the filter media layer 3, and the decay and decomposition of the dead dead livestock is made in the buried layer 4, and is generated in the process of decay, decomposition, etc. The leachate, sludge, etc. are also treated in the structure (1) itself of the present invention.

In addition, in the present invention, in forming the buried layer 4, slaked lime is mixed together with the dead livestock, and the slaked lime functions as a coagulant of the leachate. In general, quicklime is mixed, but when it comes into contact with moisture, it generates heat and absorbs heat up to about 100°C. In anticipation of sterilization by heat, quicklime is mixed in. This heat causes temperature cracks in the buried layer (5). cause.

This temperature crack acts as a point where the leachate leaks to the upper part of the buried layer 5 . Therefore, in the present invention, the temperature crack of the buried layer 5 is controlled by allowing the slaked lime to be mixed to reduce heat generation and to function as a coagulant.

In addition, the existing quicklime has a sterilization effect by heat, but in the case of slaked lime, the amount of heat is small, so this sterilization function cannot be expected.

To this end, in the present invention, the modified slaked lime coated with a sumac extract containing a phase change material on the outer periphery of the slaked lime is mixed with the dead livestock in the buried layer 4 .

The sumac extract contains urushiol as a main component. The sumac extract has a molecular structure as a phenol derivative, and it exhibits strong natural organic antibacterial functions such as strong antifungal, antimicrobial, insect repellent, and antiseptic, and has excellent durability.

Chemically synthesized antibacterial agents are generally harmful to the human body and the environment in many cases, and although the antibacterial effect is strong, the durability of the antibacterial effect is short, so there is a problem in durability. can take a long time.

As such extracts of poison ivy can be obtained through the application of various known techniques, detailed descriptions thereof will be omitted.

However, as an organic antibacterial agent, lacquer extract has poor heat resistance, so there is a problem in that the antibacterial function is lowered when exposed to heat during storage and curing.

Accordingly, in the present invention, the lacquer extract is added as an antibacterial agent, and the phase change material is included in the lacquer extract so that when the lacquer extract is exposed to decay heat, heat is absorbed by the endothermic heat of the phase change material, thereby reducing the antibacterial function due to heat to control Here, the type of the phase change material is not limited, and since various known materials exist, a detailed description thereof will be omitted.

Preferably, it is reasonable to mix 5 to 20 parts by weight of the phase change material with respect to 100 parts by weight of the lacquer extract.

Here, the slaked lime on which the lacquer extract containing the phase change material is supported on the surface is the modified slaked lime in which the phase change material component and the lacquer extract component are coated on the surface including the pores.

Meanwhile, in the present invention, as shown in FIG. 2 , an example in which the buried pipe part 6 is configured is presented.

The buried pipe part 6 has a monitor pipe 63 whose upper end is exposed to the top of the buried layer 5 and extends to the buried layer 4 , and is in communication with the monitor pipe 63 and is perpendicular to the monitor pipe 63 . It characterized in that it comprises a connection pipe 62 configured in the buried layer 4, and a flow pipe 61 protruding from the connection pipe 62 to both sides in a plurality and having a plurality of flow holes 611 formed therein. do.

The reason that the buried pipe part 6 is configured in this way is that, when a reaction such as decay or decomposition occurs in the buried layer 4, a processing gas such as sulfur dioxide is generated. This processing gas is passed through the flow hole 611 of the flow pipe 61 through the flow pipe ( 61) It flows into the interior, rides on the support pipe 62, and flows out to the ground through the monitor pipe 63. Accordingly, the manager or the like detects that the processing gas is discharged through the monitor pipe 63 and monitors the progress of decay and decomposition in the buried layer 4 according to the amount of the processing gas and the type of the processing gas. In response, an appropriate drug is injected into the monitor pipe 63 exposed to the ground, and the drug injected in this way is discharged to the buried layer 4 through the flow hole 611 of the support pipe 62-flow pipe 61. will do
