Description

Green disposal method of animals using microorganisms {Butchery disposal method of animal using microorganism}

The present invention relates to an environmentally friendly method of killing animals using microorganisms, and more particularly, to a method of killing environmentally friendly animals without contamination of the environment by quickly decomposing dead bodies of slaughtered or dead animals using microorganisms. It is about.

The treatment of dead bodies of slaughtered or dead livestock during the highly infectious infectious diseases such as foot-and-mouth disease, avian influenza, and so on has largely depended on investment methods.

Buried is a method of digging a pit of a certain depth on the ground and then spraying limestone and covering it with soil.However, it is difficult to secure adequate land, requires labor, and is difficult to prevent odors and complaints due to odor, soil and water pollution. . In particular, due to the post-leaching water problem, the treatment costs due to odors and groundwater pollution is astronomical, even though the situation is not complete treatment. In addition, there is a concern that the spread of disease is a concern if the management of the investment site is neglected.

Incineration is a method of eliminating various environmental problems due to burial and sanitizing and incineration in an incinerator of more than 800 ℃ to reduce volume and weight, and to recycle it as landfill or compost, but incinerators must be installed separately for incineration. Due to burdens, periodic inspections, and complaints, the company is reluctant to install it, and due to fuel costs, its actual utilization rate is extremely low.

In addition, the incineration method is not completely burned according to the type of the object and its moisture content, and the combustion of unburned substances, dust, pathogens, and severe odors are released into the atmosphere, suggesting a second environmental pollution problem. do.

Therefore, various devices and methods for killing animals have been developed to solve the above problems. Republic of Korea Utility Model Registration No. 20-0438349 discloses a animal carcass processing furnace.

The animal carcass treatment is a technique for treating an animal carcass by applying high temperature steam heat, but this also has a limitation in that it does not completely kill the causative agent of an infectious disease by applying high temperature steam.

The present invention has been made to improve the above problems, by using a microorganism capable of incubating at high temperatures to decompose dead bodies of slaughtered or dead animals at high temperature, there is no fear of odor and leachate generation, contamination of soil and groundwater, etc. The purpose of this method is to solve the problem of the investment method, and to provide an environmentally friendly method of killing animals that can process carcasses in a short time.

Environment-friendly killing method of the animal using the microorganism of the present invention for achieving the above object is characterized by decomposing the carcass under aerobic conditions by mixing the microbial agent with the carcass of the animal.

The disassembly of the carcass includes a) digging a pit in a selected burial ground, b) installing a water repellent membrane inside the pit, and c) spreading a breathable member on the water repellent membrane to form a base layer; d) the Forming a carcass layer in which the microbial agent and the carcass are mixed on the base layer, and e) forming a cover layer on the carcass layer so that the carcass layer is not exposed to the outside.

The method may further include supplying air into the pit to form an aerobic condition in the pit after the cover layer is formed.

And installing an air supply pipe extending from the outside of the pit after the installation of the water repellent membrane on the water repellent membrane, and supplying the air by injecting air into the air supply pipe, through the spout formed in the air supply pipe. It is characterized by supplying air to.

It characterized in that it further comprises the step of installing raining means above the cover layer in order to prevent rain from falling to the buried land after the cover layer is formed.

The carcass decomposition comprises the steps of: a) spreading a breathable member on the ground to form a base layer, b) forming a body layer on which the microbial agent and the body are mixed on the base layer, and c) exposing the body layer to the outside. It characterized in that it comprises a step of forming a cover layer on the carcass layer so as not to.

The carcass decomposition comprises the steps of a) installing a cylindrical digestion tank on the ground, b) spreading a breathable member on the bottom of the digestion tank to form a base layer, and c) mixing the microbial agent and the body on the base layer. Forming a carcass layer; and d) forming a cover layer on the carcass layer so that the carcass layer is not exposed to the outside.

The microbial agent is characterized in that cultured aerobic thermophilic bacteria that can inhabit at 50 to 60 ℃.

As described above, according to the present invention, since the carcasses of the animals are decomposed by the microorganisms under aerobic conditions, the carcasses of the animals can be sufficiently decomposed in a relatively short period of about 20 to 40 days without the occurrence of odor.

In addition, the high temperature generated during the decomposition process can kill not only various pathogens such as Salmonella and Escherichia coli, but also infectious viruses such as foot-and-mouth disease and avian influenza, and since the water evaporates rapidly due to high temperature, no leachate is generated. .

Therefore, there is no concern about the generation of odor and leachate, contamination of soil and groundwater, and provides an environmentally friendly method of killing, which can solve the problems of the conventional investment method. In addition, since all harmful bacteria and viruses are killed through high temperature decomposition, the final decomposition products of the carcass can be usefully recycled as compost.

In addition, the present invention can be applied to reprocess dead bodies buried by a conventional killing method.

Hereinafter, with reference to the accompanying drawings will be described in detail an environmentally friendly method of killing animals using microorganisms according to a preferred embodiment of the present invention.

The present invention decomposes the carcasses using microorganisms, in particular, aerobic thermophiles. In one embodiment of the present invention by applying a buried method, the carcasses are decomposed by mixing the carcasses of the microorganism with the carcasses.

Referring to FIG. 1, the present invention provides a method of digging a pit 10 at a selected investment site, installing a water repellent film (not shown) inside the pit 10, and forming a base layer 20 on the water repellent film. And forming a dead body layer 30 on the base layer 20, and covering the dead body layer 30 to form a cover layer 40.

The microbial agent applied to the present invention means that a culture medium in which a microorganism is cultured is mixed with a carrier. As a carrier, rice bran, sawdust, bran, fallen leaves, hay, compost or the like can be used.

In the present invention, it is preferable to use an aerobic microorganism capable of decomposing the body of an animal with a microorganism. The present invention can prevent the generation of odor during the decomposition of the carcass by decomposing the carcass of the animal under aerobic conditions. In particular, it is preferable to use a thermophilic bacterium which can inhabit at high temperature of 50-65 degreeC among aerobic microorganisms. By such aerobic thermophilic bacteria it is possible to decompose the dead body at 50 to 65 ℃ high temperature. Aerobic thermophiles are available on their own or commercially available in the process of composting or ripening livestock manure.

As an example of aerobic thermophilic bacteria, Bacillus stearothermophilus may be used. Bacillus stearromophilus is a known thermophilic bacterium that shows positive reactions in Gram staining experiments, forms spores and actively grows under aerobic conditions.

A brush as Bacillus stearate Russ (Bacillus In addition to stearothermophilus , Speroterius Nautau , Bacillus subtilis), also Pseudomonas Manas (Rhodopsudomonas), also RY rilrum (Rhodospirillum), Bacillus Sono alkylene sheath (Bacillus sonorensis ), Bacillus thermoamylovorans ( Bacillus thermoamylovorans ) alone or a mixture of two or more is preferably used.

The microorganisms are cultured by inoculating the medium. The medium may be formed by, for example, adding tryptone, yeast extract, yeast extract, glucose, sodium chloride (NaCl), and potassium hydrogen phosphate (K ₂ HPO ₄ ) to water. For example, tryptone 3g, yeast extract 3g, glucose 3g, NaCl 5g, K ₂ HPO ₄ 1g is added to 1ℓ of distilled water. After inoculating the strain into the medium and incubated for 1 to 3 days at 30 to 40 ℃ to obtain a culture solution. And the culture solution is mixed with the carrier. The culture solution is adsorbed to the carrier so that the microorganisms are fixed to the carrier. At this time, the culture medium to the carrier may be mixed in a weight ratio of 1:10 to 50.

The prepared microbial agent is mixed with the carcasses of the animals to decompose the carcasses of the animals.

First, a burial site for burying a corpse is selected. When the investment site is selected, the pit 10 is dug to a predetermined depth at the selected location. In addition, a water barrier may be installed to prevent the surface water from flowing into the pit 10. The shield is installed inside the pit as shown in FIG. A vinyl film can be used as the order film.

Next, the base layer 20 is formed. The base layer 20 serves to smooth the breathability of the lower portion of the pit 10 and to control moisture. In addition, it absorbs rainwater flowing into the pit during rainy weather or leachate that can occur during carcass decomposition. As a material for forming the base layer 20, a breathable member that can be ventilated is used. The breathable member is preferably decomposable by microorganisms. As the breathable member, at least one selected from rice bran, sawdust, fallen leaves, hay, and compost, or a mixture of two or more thereof may be used.

The breathable member is introduced into the pit 10 to spread widely on the bottom of the pit 10 to form the base layer 20. In the case of installing the shield, a base layer is formed on the shield. The thickness of the base layer 20 can be suitably adjusted in the range of 20-50 cm. 17 illustrates a state in which the chaff is introduced into the pit using a fork lane to form the base layer 20.

Next, on the base layer 20 to form a carcass layer 30 is mixed with a microbial agent and carcass. To do this, mix the microbial preparation and the carcass outside the pit. For the action of microorganisms, it is preferable to use a microbial agent by adjusting the water content to 50 to 60% by weight. Therefore, the ground water is sprayed on the microbial preparation to adjust the water content to 50 to 60% by weight and then mix with the carcass of the animal. Carcass and microbial agent can be mixed in a volume ratio of 1: 0.5 to 1.5.

Carcasses mixed with microbial preparations are introduced into the pit using heavy machinery. Carcasses mixed with the microbial agent are stacked on the base layer 20 inside the pit 10 to form a carcass layer 30. At this time, the carcass layer 30 is formed lower than the height of the ground.

After forming the carcass layer 30, the cover layer 40 is formed on the carcass layer so that the carcass layer 30 is not exposed to the outside. To this end, the chaff is stacked on the carcass layer 30 to form a cover layer 40. The cover layer is formed using a breathable member that can be ventilated. In addition to rice bran such as chaff as a breathable member, sawdust, fallen leaves, hay, compost, etc. can be used.

The cover layer 40 is preferably formed convexly in the form of a rod to increase the contact area with the atmosphere. The cover layer 40 of this type has an effect of facilitating the respiration of microorganisms and widening the evaporation area of moisture.

The body is decomposed by the microorganisms after a certain period of time after the buried work is completed by forming the cover layer 40. Although the decomposition treatment period is slightly different depending on the amount of dead bodies and the weather, the carcasses are sufficiently decomposed after 20 to 40 days.

In the early stages of decomposition, in addition to the microorganisms inhabiting microbial preparations, the carcasses are decomposed by various bacteria, actinomycetes, filamentous bacteria, etc. that exist in nature. Decomposition of microorganisms proceeds using amino acids, organic acids, minerals, etc. of the carcass, and heat is generated by the respiration heat of the microorganisms, and the generated heat is accumulated to raise the temperature of the carcass buried layer to 50 to 65 ° C. As the temperature rises, the cryogenic bacteria die and only very limited thermophilic bacteria continue to degrade. This high temperature decomposition process at 50 to 65 ℃ kills not only various pathogens such as Salmonella, Escherichia coli and the like, but also infectious viruses such as foot-and-mouth disease, avian influenza, and the like. Therefore, in the decomposition process, the maximum temperature should be at least 50 ° C. or more, and the duration is preferably maintained at least 10 to 30 hours.

As described above, the decomposition process of high temperature by aerobic thermophile does not generate odor by oxygen breathing. The high temperature of 50 to 65 ℃ generated in the process of carcass decomposition evaporates the water so there is no generation of leachate. Finally, when the carcass is decomposed by the microorganisms, the contents of the pit can be useful for composting. As described above, the present invention is an environmentally-friendly killing method that can decompose a dead body in aerobic conditions at an expiratory condition by using microorganisms, and there is no fear of contamination of soil and groundwater because no odor and leachate are generated. In addition, the present invention can be applied to reprocess dead bodies buried by a conventional killing method.

In another embodiment of the present invention, after forming the cover layer, the step of supplying air into the pit to form aerobic conditions in the pit may be further performed.

To this end, an air supply line is installed before or after forming the base layer. 2 shows an internal view of the pit 10 in which the air supply pipe 55 is installed. The air supply pipe 55 is connected to the blower 50 installed outside the pit 10. As the air supply pipe 55, a flexible hose can be used. The air supply pipe 55 is installed in a zigzag. The air supply pipe 55 is formed with a plurality of ejection openings so that air can be ejected into the pit 10.

After the air supply pipe 55 is installed, the base layer 20, the dead body layer 30, and the cover layer 40 are sequentially formed, and then the blower 50 is operated to supply air into the air supply pipe 55. In this way, the air can be supplied into the pit to maintain the inside of the pit 10 under aerobic conditions.

Meanwhile, in the illustrated example, the air supply pipe is installed under the base layer. Alternatively, the air supply pipe may be installed on the base layer after forming the base layer. In addition, in the case of installing the barrier film in the pit, as shown in FIG. 16, an air supply pipe may be installed on the barrier film.

In addition, a vent pipe communicating with the outside may be installed in the pit as a method for forming aerobic conditions in the pit.

3 and 4, the vent pipe 60 includes a first oil pipe 61 and a second oil pipe 65 installed inside the first oil pipe 61 and the first and second oil pipes 61. Between the (65) and the microbial agent (69) is filled.

The first oil pipe 61 has a hollow pipe shape, and a plurality of through holes 63 are formed. In addition, the second oil hole tube 65 has a hollow inner pipe shape having an outer diameter smaller than that of the first oil hole tube 61. A plurality of through holes 67 are formed in the second oil pipe 65. The upper part of the vent pipe is provided with a blocking roof 70 to prevent rainwater inflow. The microbial agent 69 is filled between the first oil pipe 61 and the second oil pipe 65. Air circulated from the inside of the pit to the outside of the pit may be removed by the microbial agent (69) filled between the first oil hole 61 and the second oil hole (65).

The vent pipe 60 is installed vertically in the pit 10. One or more vent pipes 60 may be installed. Installation of the vent pipe 60 may be performed before the base layer 20 is formed in the pit 10 or after the base layer 20 is formed.

Components not described in FIGS. 3 and 4 are the same as in FIG. 1.

Meanwhile, as shown in FIG. 21, in another embodiment of the present invention, after the cover layer 40 is formed, the method may further include installing raining means 90 to prevent rain from falling into the buried land. Small amount of rain does not need raining means because it evaporates during decomposition at high temperature even if it flows into the buried land, but raining means is useful when a lot of rain falls at a time like rainy season. Raining means 90 may be configured in the form of a dome-shaped house. For example, a semi-arc pipe 91 is installed around the inlet of the pit at regular intervals, and then the vinyl 95 is spread on the pipe to form a roof. Both sides and the front and rear surfaces of the house have an open structure so that air can flow.

Components not described in FIG. 21 are the same as in FIG.

The method of killing according to another embodiment of the present invention decomposes a carcass of an animal by depositing on a flat ground rather than digging a pit.

Referring to FIG. 5, the base layer 81 is formed by spreading at least one selected from a breathable member, ie, rice bran, sawdust, fallen leaves, hay, and compost, on the flat ground 80. The ground 80 may be applied to the ground, or a concrete floor in a barn. The microbial agent is the same as in the above-described embodiment.

After the base layer 81 is formed, a body layer 83 in which a microbial agent and a body are mixed is formed on the base layer 81. The carcass layer 83 is formed by stacking on the base layer 81 after mixing the microorganism agent and the carcass. After the body layer 83 is formed, the cover layer 85 is formed by covering the body layer 83 so that the body layer 83 is not exposed to the outside. To this end, the chaff may be stacked and covered on the carcass layer 83.

And the present invention can of course supply air to the air supply pipe installed on the base layer 81 to form aerobic conditions after covering the carcass layer (83).

22 shows the inside of the pit to which the killing method is applied according to another embodiment of the present invention. Referring to Figure 22, the pit in the buried land is not deeply formed to form a shallow depth of about 50cm from the ground. And the soil discharged when forming the pit is stacked at the edge of the pit inlet to form a weir (100). In this way, digging a pit can create enough space to bury a dead body without digging deep. After the pits are dug, the inner membrane of the pit is installed, the base layer 103 is formed on the secondary membrane 101, and the air supply pipe 115 connected to the blower 110 is installed on the base layer 103. Then, after forming the dead body layer 105 mixed with the microbial agent and the dead body on the base layer 103 to form a cover layer 107 on the dead body layer.

23 shows the inside of the decomposition tank 120 to which the killing method according to another embodiment of the present invention is applied. Referring to FIG. 23, a movable disassembly tank 120 is used to decompose a corpse and not to dig a pit or to deposit a ground.

The decomposition tank 120 is a cylindrical structure with an open top. Decomposition tank 120 may be formed in a variety of shapes, such as cylindrical, square tubular. The decomposition tank 120 may be made of a synthetic resin or a metal material with strong corrosion resistance. The decomposition tank 120 can be transported on a truck.

Looking at the killing method using the digestion tank 120, the prepared digestion tank 120 is transported to the truck to move to the farm where the infectious disease occurred. The digester 120 is laid down on the flat ground in the farm. In addition, the base layer 131 is formed by spreading a breathable member such as chaff at the bottom of the decomposition tank 120. Next, the air supply pipe 155 connected to the blower 150 is installed in the base layer 131. Then, the dead bodies mixed with the microbial agent are stacked on the base layer 131 to form a dead body layer 133, and then the overlying dead body layer 133 is covered with chaff to prevent the dead body layer 133 from being exposed to the outside to form a cover layer 135. do. In addition, when water or leachate is generated at the bottom of the decomposition tank 120 in the decomposition process, a circulation pipe 140, a pump 141, and a spray pipe 145 may be installed to be sprayed onto the cover layer 135.

Meanwhile, in the above-described embodiment, after the cover layer is formed, the decomposition tank can be decomposed for a predetermined period of time by leaving the decomposition tank in the farm as it is. Alternatively, after forming the cover layer, the decomposition tank is moved to a separate place to decompose the process. You can proceed.

Hereinafter, the present invention will be described through experimental examples. However, the following experimental example is for describing the present invention in detail, and the scope of the present invention is not limited to the following experimental example.

Experimental Example 1

In two farms of high pathogenic avian influenza in Yeoncheon, Gyeonggi-do, the carcasses of slaughtered chickens were mixed with a microbial agent and then killed for 4 weeks. The microbial preparation was prepared by mixing the microbial culture solution (Naeae, Micromax farming corporation) and rice husk in a weight ratio of 1:30 and then spraying groundwater to adjust the moisture content to 60% by weight.

After installing the air supply pipe connected to the blower on the concrete floor by the method of killing, the chaff was laid to form a base layer, and the microbial preparation and the carcass of the chicken were mixed in a volume ratio of 1: 1 using a fork lane. A mixture of microbial preparations and chicken carcasses was stacked up to form a carcass layer, covered with chaff, and digested for 4 weeks while supplying air to the air supply tube. This killing process is shown sequentially in FIGS. 6 to 9.

At the interval of one week after the killing, the temperature of the core and surface of the yard, odor occurrence, maturity, and death of the virus were examined.

As a result of the experiment, the surface layer (depth 10 cm) was 55 ° C to 45 ° C in week 1, 54 ° C to 42 ° C in week 2, and 45 ° C to 29 ° C in week 3. And the core part (depth 50cm) showed 55 degreeC-41 degreeC in the 1st week, 54 degreeC-41 degreeC in the 2nd week, and 45 degreeC-28 degreeC in the 3rd week.

Odor change was carried out by sensory test at 3m and 10m away from the field. From week 1 to week 2, there was a strong compost odor, and at week 3 there was a weak compost odor. In the color change to determine maturity, brown color appeared at 2 weeks, and dark brown color at 3 weeks.

In addition, the virus test was carried out to find the carcasses of chickens being disintegrated in the yard, steal the total excretory river with a cotton swab, and inoculate them with the AIV Ag Test Kit (BioNote, Inc) and 9-day-old eggs. The virus was killed at 2 weeks on the dog farm, but the virus was isolated until 3 weeks at the other farm, but after 4 weeks, the virus was negative.

Experimental Example 2

Carcass decomposition experiments were carried out using pig carcasses raised during farming in Naju, Jeollanam-do. The same microorganism formulation as that used in Experimental Example 1 was used.

Using the empty space of the barn, the microbial preparation was piled up in the shape of a rod, buried a pig carcass in it, and the decomposition process over time was visually examined.

Figure 10 is a state of the pig carcass at landfill. And it was confirmed that the flesh is decomposed three days after landfill (Fig. 11). The carcasses continued to decompose on day 5 after landfilling, and no leachate occurred. In addition, only a slight compost smell or odor did not occur (Fig. 12). At 15 days after reclamation, all flesh was broken down, leaving only bone. The bone was broken down to the extent that it was broken by hand (Figure 13). And 35 days after reclamation, only the jawbone remained and all the rest was confirmed to be disassembled (Fig. 14).

Experimental Example 3

The carcasses of slaughtered pigs were killed on farms where foot-and-mouth disease occurred in Hongseong-gun, Chungcheongnam-do. The same microorganism formulation as that used in Experimental Example 1 was used.

After the pits were plated using the fork lane in the selected investment site (FIG. 15), the membrane was installed inside the pit, and then the air supply pipe was installed (FIG. 16). Next, the chaff was put into the pit to form a base layer (Fig. 17). Then, after forming a carcass investment layer in which the microbial agent and carcasses were mixed on the base layer (Fig. 18), the chaff was stacked on the carcass investment layer to form a cover layer (Fig. 19).

The carcasses of pigs 30 days after embedding are shown in FIG. 20. As shown in FIG. 20, the body was almost decomposed and only some bones remained.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be clearly understood that the same is by way of illustration and example only and is not to be taken by way of limitation.
