Description

Avian flu and foot-and-mouth disease virus disinfectant using liquid slaked lime, and a manufacturing method therefor {GERMICIDE FOR VIAN INFLUENZA AND FOOT AND MOUTH DISEASE VIRUS USING LIQUID LIME HYDRATE AND METHOD OF MANUFACTURE THEREOF}

The present invention relates to an avian flu and foot-and-mouth disease virus disinfectant using liquid slaked lime and a method for manufacturing the same, and more particularly, to avian influenza (AI), foot-and-mouth disease (FMD) and African swine fever (ASF) viruses without causing environmental pollution. It relates to an avian flu and foot-and-mouth disease virus disinfectant using liquid slaked lime, which can effectively sterilize and disinfect, and a method for manufacturing the same.

Today, highly contagious and fatal virus-induced infectious diseases such as foot-and-mouth disease and PRRS, which are livestock infectious diseases, as well as zoonotic diseases such as bird flu and swine flu, are causing social problems.

Foot-and-mouth disease virus is a very important disease for livestock, classified as Class A by the Office International des disease, and belongs to the first type of livestock infectious disease in Korea. All animals with split hoofs such as cows, pigs, sheep, goats, and deer can be infected, and the disease is highly contagious and blisters are formed on the lips, tongue, gums, nose, and between the hooves at the initial stage of infection. Symptoms such as a rapid rise in body temperature and loss of appetite appear, leading to acute death.

In addition, avian influenza (AI or Bird flu) is an acute viral disease that infects chickens, ducks, turkeys, and wild birds. In Korea, it is classified as a list A class by the OIE (International Fisheries Service), the first kind of livestock infectious disease. The causative agent, avian influenza virus, is a common viral virus, and is classified into highly pathogenic, weakly pathogenic, and non-pathogenic according to pathogenicity, and can be classified into 135 types according to serotype (15 types of HA protein, 9 types of NA protein).

Avian influenza viruses that have recently been transmitted to humans include H5N1 and H9N2. Avian influenza viruses are spread by droplets, air, and water, but the main transmission factor is feces on human hands, feet, feed trucks, tools, and equipment. buried and spread indirectly.

Around the world, poultry deaths due to avian influenza virus infection, costs for culling, labor costs for prevention, and environmental pollution damage due to quarantine are occurring repeatedly every year without special countermeasures.

When avian influenza occurs, most countries around the world slaughter and dispose of all of them in landfills, and poultry products cannot be exported to the affected countries. Therefore, a huge loss is caused not only to the poultry farms, but also to the national and poultry farms.

Looking at the domestic and overseas trends on avian influenza, in Korea, the development of avian influenza vaccine is in progress, and the Ministry of Agriculture, Food and Rural Affairs and government research institutes are reviewing the safety of future use. In the current situation, prevention such as limiting the movement of poultry and feed transport vehicles and people is being implemented.

However, despite these efforts, as revealed in the recent domestic foot-and-mouth disease outbreak, the current quarantine system has exposed loopholes that cannot effectively block the spread of the virus. In addition, when large-scale culling of livestock is performed due to foot-and-mouth disease or avian influenza, many side effects such as leachate contamination are caused.

Overseas, the US and some advanced countries have completed the development of an avian influenza vaccine, but the safety of its use is under review. there is a situation.

However, when avian influenza vaccine is used, it is economically expensive and it is urgently needed to find a new way to prevent avian influenza in that it can promote new virus mutation.

However, the present invention may be embodied in several different forms and is not limited to the embodiments described herein. And in order to clearly explain the present invention in the drawings, parts irrelevant to the description are omitted, and similar reference numerals are attached to similar parts throughout the description of the invention.

Hereinafter, specific technical contents to be practiced in the present invention will be described in detail with reference to the accompanying drawings.

first embodiment

1 is a flowchart illustrating a method for manufacturing avian flu and foot-and-mouth disease virus disinfectant using liquid slaked lime according to a first embodiment of the present invention.

First, water (H ₂ O) and quicklime (CaO) are mixed in a ratio of 70-80 wt%: 20-30 wt%, and then hydrated and hydrated by high-speed stirring for 10-30 minutes at a rotation speed of 2000 RPM or higher in a centrifuge Grinding is performed together to obtain liquid slaked lime (Ca(OH) ₂ ) having a liquefaction of 1000 mesh or more (step S10). At this time, the liquefied state with a particle size of 1000 mesh or more maintains a suspension state without classification like milk.

The liquid slaked lime (Ca(OH) ₂ ) is a chemical substance that is hydrated by adding water to quicklime (CaO). Although the molecular formula is different, it has almost the same properties in terms of function. Liquid slaked lime (Ca(OH) ₂ ) and quicklime (CaO) both have strong alkalinity of PH12 and exhibit the same effect of chemical disinfection.

The quicklime (CaO) is calcium oxide (CaO) prepared by burning limestone (CaCO3) at a high temperature (1,000 ~ 1,200 ℃). Quicklime absorbs moisture well, shows basicity when dissolved in water, heats up when hydrated, and increases in volume, so be careful when storing or using it.

The liquid slaked lime (Ca(OH) ₂ ) is a chemical substance that is hydrated by adding water to quicklime (CaO). It is a product that maximizes the convenience of storage and use and has a faster reaction than quicklime. The principle of disinfection is the same strong alkaline disinfection as quicklime, and the disinfection method is more convenient than the powder. The liquid slaked lime (Ca(OH) ₂ ) can be stored anywhere and can be sprayed without difficulty even for beginners by improving the difficulty of storage and the inconvenience of spraying, which are disadvantages of powdered quicklime (CaO).

The liquid slaked lime (Ca(OH) ₂ ) has a calcium oxide (CaO) powder of 88% or more, a calcium hydroxide (Ca(OH) ₂ ) content of 20±1 to 30±1%, PH 12 to 13, and a specific gravity of 1.08 ±0.5 to 1.10±0.5, impurities 0.3% or less, particle size 1000 mesh or more pass 95%, and CSH is formed through hydration and pozzolan reaction.

In the present invention, liquid slaked lime (Ca(OH) ₂ ) having a particle size of 1000 mesh or more liquefaction can be prepared and disinfected by spraying with a sprayer.

The liquid slaked lime (Ca(OH) ₂ ) is sprayed in a liquid phase to suppress pathogens and airborne bacteria and fungal growth, and to sterilize and disinfect avian influenza (AI), foot-and-mouth disease (FMD) and African swine fever (ASF) viruses. can do.

The present invention uses a centrifugal separator to obtain liquid slaked lime having a particle size of 1000 mesh or more, and can be diluted with water and sprayed on the soil with a sprayer. absorbed very quickly.

In addition, since it is sprayed with a sprayer, it can be evenly distributed on the soil unlike granular slaked lime, and it is absorbed with water and stays in the soil in the state of fine particles to exert a disinfecting effect for a long time.

Next, the liquid calcium hydroxide (Ca (OH) ₂₎ are mixed ionized mineral particles 3-5% by weight, based on the liquid calcium hydroxide (Ca (OH) ₂₎ 100% by weight (step S20).

A method for preparing the ionized mineral particles is as follows.

First, calcined minerals obtained by calcining shellfish shells at 1,000° C. to 1,300° C. for 2 hours are pulverized with a grinder to make powders with a particle size of 100 to 200 mesh.

After that, ultrasonic waves of 30W are repeated 2-3 times for 10-15 minutes on the mineral particles meshed with the powder to make the particle size 100-150 nm, and then electrolyzed in a state of dissolving the nano-sized mineral particles in water. Ionize the mineral particles.

The ionized mineral nanoparticles contain Mg, Na, K, P, S, Fe, Zn, and the like, and generate hydrogen anions by reaction with _{the liquid slaked lime (Ca(OH) 2 ).} At this time, the generated hydrogen anions are excellent in sterilizing bacteria and viruses and do not cause environmental pollution.

Next, in a mixture in which the liquid slaked lime (Ca(OH) ₂ ) and the ionized mineral particles (3 to 5% by weight) are mixed, sodium cyanate (based on 100% by weight _{of the liquid slaked lime (Ca(OH) 2 )} NaOCN) 0.5 to 1.0% by weight (step S30).

The sodium cyanate (NaOCN) is a white crystalline solid, and in the disinfectant composition of the present invention, it is a substance used as an oxidizing agent that destroys proteins of viruses by oxidation. In addition, in the disinfectant composition of the present invention, the added amount is preferably 0.5 to 1.0% by weight.

On the other hand, the present invention is _{glutaraldehyde (C6H802) 0.5 in the liquid lime (Ca(OH) 2} ) in a mixture of 3-5 wt% of the ionized mineral particles and 0.5-1.0 wt% of the sodium cyanate (NaOCN) It may be configured by mixing wt%.

As described above, in the first embodiment of the present invention, 3 to 5 wt% of the ionized mineral particles and 0.5 to 1.0 wt% of the sodium cyanate (NaOCN) are mixed in the _{liquid slaked lime (Ca(OH) 2 ).} Avian influenza and foot-and-mouth disease virus disinfectants can be manufactured.

second embodiment

2 is a flowchart illustrating a method for preparing an avian flu and foot-and-mouth disease virus disinfectant using liquid slaked lime according to a second embodiment of the present invention.

In the second embodiment of the present invention, after the step (S30) of the first embodiment, the step (S40) of mixing magnesium (Mg), calcium (Ca), and charcoal powder is additionally configured.

According to the step (S40), in the liquid slaked lime (Ca(OH) ₂ ), in a mixture of 3 to 5 wt% of the ionized mineral particles and 0.5 to 1.0 wt% of the sodium cyanate (NaOCN), magnesium (Mg ) 2 to 3% by weight, calcium (Ca) 1 to 2% by weight, and 5 to 10% by weight of charcoal powder having a particle size of 100 to 200 mesh are mixed.

The magnesium (Mg) and calcium (Ca) metals are known to have very strong reactivity with water or oxygen.

When the magnesium (Mg) and water (H ₂ O) react, magnesium hydroxide (Mg(OH) ₂ and hydrogen (H ₂ ) gas are generated.

Mg + 2H ₂ O → Mg(OH) ₂ + H ₂ ↑

Here, Mg(OH) ₂ is Mg2 ⁺⁺ , 2OH ^{_ as an} ion, and hydroxide ions are generated.

Similarly, when the calcium (Ca) and water (H ₂ O) react, calcium hydroxide (Ca(OH) ₂ and hydrogen (H ₂ ) gas is generated.

Ca + 2H ₂ O → Ca(OH) ₂ + H ₂ ↑

Here, Ca(OH) ₂ is Ca2 ⁺⁺ and 2OH ^{_ as} ions, and hydroxide ions are generated.

The hydrogen anion generated here functions to sterilize and sterilize not only various bacteria and viruses, but also avian influenza and foot-and-mouth disease viruses.

Charcoal is carbonized by burning wood and contains most of the carbon and some minerals and volatile matter. Charcoal has deodorizing action, antiseptic action, humidity control action, etc., as is widely known, and in recent years, the efficacy of far-infrared rays and negative ions that are beneficial to the human body, electromagnetic wave blocking action, sterilization action, etc. have been proven.

Charcoal emits a large amount of negative ions, sterilizes and purifies bacteria and viruses by adsorption and purification power, and performs air purification and odor purification functions.

another embodiment

As another embodiment of the present invention, the liquid slaked lime (Ca(OH) ₂ ), by adding sodium bicarbonate to raise the pH to 75-85 glutaraldehyde (C ₅ H ₈ O ₂ ) solution 2-3 It can be composed by mixing % by weight.

The molecular weight of the glutaraldehyde (C ₅ H ₈ O ₂ ) is 100 g/mol, and it is an acidic solution of a colorless, volatile liquid with a pungent odor and has very little disinfection effect. However, when the pH is raised to 75-85 by adding a base, it is activated and becomes a powerful disinfectant that can also kill bacterial spores.

_{In general, a 2% glutaraldehyde (C 5} H ₈ O ₂ ) solution that raises the pH to 75-85 by adding sodium bicarbonate kills general bacteria within 2 minutes, Mycobacterium tuberculosis, fungi, and viruses within 10 minutes. , Bacillus (Bacullus) and Clostridium spores are killed within 3 hours, Clostridium difficile spores are known to kill within 20 minutes.

As another embodiment of the present invention, the liquid slaked lime (Ca(OH) ₂ ) may be configured by mixing a bromine-based disinfectant.

Since the bromine-based disinfectant is not irritating to the human body and has a wide range of sterilizing power and durability, it is a component that can be applied to a lime composition for sterilization and expect a long sterilization effect. Specifically, as the bromine-based disinfectant, one or a mixture of two or more selected from sodium bromide, potassium bromide, calcium bromide and hydrobromic acid may be used.

The liquid slaked lime of the present invention is difficult to store due to the fact that the powder flies when spraying the conventional powdered quicklime, there is a difficulty in uniform application, a large amount of application is required, there is a risk of burns during handling, and there is a risk of explosion It has the effect of solving both difficult and difficult problems.

Efficacy experiment of liquid slaked lime

1. Introduction

In the case of an infectious disease such as swine fever, if a contagious disease such as swine fever occurs, the entire or nearby livestock farms are collectively buried and disposed of as a group of livestock farms that are several kilometers away from the whole or nearby livestock farms. Should be. In particular, swine fever is a disease that has a very large impact on the national economy due to the cost of disease control such as slaughter and vaccination, reduced productivity, and restrictions on international trade in animals and livestock products.

This experiment sterilizes organic pathogens and harmful bacteria inhabiting the barn to prevent various seasonal infectious diseases in advance and to improve the immunity of livestock. Harmful pathogen analysis was performed. In this experiment, sterilization of harmful pathogens, collection of various harmful microorganisms inhabiting the environment and soil of the barn, and improvement of the breeding environment were carried out on the finishing pig farm in Miryang-si and the finishing pig farm in Haman-gun. When infectious diseases such as cholera occurred, many livestock were buried in groups, resulting in problems in animal welfare and wasting the national budget. However, by periodically spraying liquid slaked lime for livestock farms, the effect analysis of suppressing the growth of pathogens and airborne bacteria and fungi living in the farm, and the corrosion test of the water pipe supplied to the livestock farm were conducted. Since it can affect the health of industry and workers in common, it is an important time to promote eco-friendly breeding and secure the right to health through management of related harmful factors. Studies on the effects of infectious diseases on the health of domestic animals by eradicating microorganisms that spread various organic pathogens inhabiting farms are inexhaustible. Therefore, in this experiment, in order to derive the effect of quicklime on harmful microorganisms and corrosive properties, the results were analyzed and reviewed by conducting an experiment over a total of 5 weeks, including the analysis of harmful pathogens occurring on the farm and the corrosion test of the water pipe supplied to the breeding grounds. did.

2. Theoretical Background

Disinfection is to prevent direct harm to non-hospital microorganisms, and is used as a term for sterilization or disinfection, which should be distinguished according to the degree of sterilization treatment of hospital microorganisms contaminated with containers or materials. It completely kills all attached microorganisms, and sterilization means sterilizing pathogenic microorganisms for a certain purpose existing on the object. Disinfection is one way to prevent damage caused by infectious diseases in advance by eradicating pathogens that are at risk of infecting livestock and microorganisms that transmit the pathogens, and there are several ways to prevent the occurrence or spread of livestock infectious diseases. However, among them, disinfection is one of the most important methods. When disinfecting with a disinfectant, it should be carried out under various favorable conditions. Ideal conditions are strong disinfection power, effective in small amounts, soluble in water, and long-lasting, low toxicity, and damage to the object to be disinfected in order to disinfect a wide range of livestock. shouldn't

Since it takes about 2 weeks for bacteria or viruses to return to the original state after disinfection, the interval between barn disinfection is 10 to 14 days, but in this experiment, it was conducted at intervals of 7 days.

On the other hand, factors affecting the corrosion of metal materials in the farm include physical factors such as the type of metal and temperature of the material, pH, alkalinity, total dissolved solids (TDS), hardness, dissolved oxygen, and residual chlorine. , chemical factors such as sulfate ions, buffer intensity, and biological factors such as bio film and the presence of microorganisms.

LI expresses the precipitation potential of calcium carbonate in water and is defined by Equation (1). When LI is greater than 0, precipitation of calcium carbonate occurs, and when LI is less than 0, dissolution of calcium carbonate occurs. Therefore, there is a certain correlation between the actual LI and the corrosion of the facilities on the farm, and the correlation between the LI and the corrosion of the facilities on the farm can be expressed as shown in Table 1.

LI = pH - pHs ------------------------------------- Equation (1)

pHs = A + B - log[Ca] - log[alkalinity]

Here, pH is a measured pH value, and pHs is a pH value when calcium carbonate is saturated. A and B are water temperature, TDS-related constants, calcium and alkalinity, respectively, CaCO ₃ equivalent concentration (mg/L). For liquid slaked lime, 20% liquid slaked lime solution that can be safely used in general farms was used. Carbon dioxide was dissolved in distilled water to adjust the pH to 3.91, and then used for the experiment. On the other hand, organic matter, that is, most pathogens, coexist with organic matter such as poop or urine (washing of manure, etc.), so the effectiveness of disinfection can be reduced by organic matter, and the livestock must be thoroughly cleaned using a high-pressure washer, etc. After washing with water or using a cleaning aid (surfactant), etc. to remove organic matter, liquid slaked lime was applied as the disinfectant in this experiment, and glutaraldehyde was used at a concentration of 1-2% and disinfected even in the presence of some organic matter. It is effective. Because it is expensive, disinfection cost is high for mass use. Formaldehyde is used at a concentration of 8% formalin (formaldehyde 40% solution), and the disinfection effect is similar to that of glutaraldehyde.

to be. It reacts with the slaked lime produced during the hydration reaction to increase the proportion of cement solidified CSH material, and CAH is generated by Alumina.

Liquid slaked lime inhibits the growth of microorganisms due to the exothermic reaction that occurs during hydrothermal reaction along with high pH in preventing harmful pathogens and decay, and the decay rate of organic matter is also reduced. In general, maintaining a pH of 12 or higher inhibits the part's pathogen activity. Table below. As in 2., Pseudomonas species and Salmonella were killed below the detection limit during lime stabilization treatment.

_{In addition, H 2} S is generated due to the decomposition of microorganisms in the various sludges in the barn before the solidification treatment due to the liquid slaked lime spraying, and at this time there is a smell of rotten eggs. However, by injecting lime, the growth of microorganisms is reduced due to the increase in pH, so that organic material decomposition does not occur, and as the pH is raised to 9 or higher, H ₂ S is present as volatile and the smell is reduced.

2-2. LI (Langelier saturation index) theory

The Langelier saturation index (LI) was developed in 1936 by Langelier as an index to determine the tendency of calcium carbonate (CaCO3) scale generation in water. LI is an index that predicts whether calcium carbonate will precipitate as a thin film on the tube surface to form scale from the relationship between hydrogen ion concentration and alkalinity and saturated pHs of water. If calcium carbonate scale is formed on the inner wall of the water supply pipe, it can act as a corrosion-resistant film and inhibit the corrosion of the pipe surface by tap water.

The calcium carbonate saturation index LI is calculated as in Equation (1).

LI = pH - pHs ---------- (Equation 1)

Here, pH = measured value pHs = pH at CaCO3 equilibrium in the presence of calcium ions and bicarbonate ions

The pHs are calculated as in equation (2).

pHs= pK2- pKs+ p[Ca2+] + p[HCO3-] + 5 pfm ------------ (Equation 2)

3. Experimental method

This experiment was conducted using liquid slaked lime and water 300-400g per square meter (approximately 1kg per pyeong) for soil disinfection of farms and barns located in Miryang-si and Haman-gun. Also, the corrosive index of groundwater supplied to the farm was measured. evaluated.

3-1. Microbial changes before and after liquid slaked lime disinfection

Disinfection of the farm for this experiment is carried out in the morning on a sunny day, and the alkaline aqueous solution for cleaning the farm is prepared at about 3 liters (about 3 mm solidification) per 1 m2, and the disinfectant is about 2 liters per 1 m 2 (about 2 mm solidification). Prepare and pour enough. If there is rice husk, straw, or powder in the farm, ferment and sterilize it. That is, dig a suitable groove about 1~2m in width and 20cm in depth, spray slaked lime, pile up powder, litter, etc. to a height of 1~2m, cover with soil or vinyl, etc. to prevent contact with the outside, and leave it for about 2 weeks. The temperature of fermentation is about 60~70℃, and the temperature is continued for several days. For sample collection, the solution flowing down from the farm floor is collected on a weekly basis, put into an experimental beaker, and the strain and individual of microorganisms are analyzed with a high-magnification microscope. Enter the value.

3-2. Corrosion index change using liquid slaked lime

Using direct water coming into the farm, the sample to be analyzed, as the undiluted solution, dilute a 25% solution of liquid slaked lime with a 100mg/L solution, and take 5mg/L, 10mg/L, 15mg/L, and 20mg/L each of this solution into a beaker. It was put into the farm and quantified in an amount of 1000 mL with direct water used in the farm.

Hydrogen ion concentration is the most important factor influencing corrosion. Normally, water has a pH between 4.3 and pH 10 in its natural state. The corrosion rate is increased in the acidic state, and the corrosion rate is decreased in the alkaline state. It is recommended to maintain pH 6 or higher to prevent corrosion, but at pH 8 or higher, scale may be generated in calcium carbonate or calcium phosphate. The hydrogen ion concentration was measured according to the water pollution process test standard.

In this experiment, the dissolution test was conducted using iron and powder (Kanto. Assay 90%). Using direct water taken from the farm as the stock solution, 0.1g of iron powder was added to 1000mL of tap water as a control group, and about 25% of liquid slaked lime was added to tap water. After adjusting the solution to a concentration of 100 mg/L, the solution was diluted step by step to adjust the concentration to 5 mg/L, 10 mg/L, 15 mg/L, and 20 mg/L. After putting 0.1g of iron powder in each beaker, the Jar Tester was rotated at 100 revolutions per minute for 24 hours, 48 hours, and 72 hours stirring process. The liquid slaked lime concentration values are shown in Table 4.

According to the comparative analysis before and after liquid slaked lime disinfection, it can be seen that the change in the resistance of microorganisms, which is harmful to pathogens, is reduced as shown in Table 5. below.

Here, the classification of pathogenic microorganisms is divided into three types: microorganisms belonging to the most resistant microorganisms and microorganisms belonging to the microorganisms with moderate resistance and the microorganisms belonging to the weakest resistance. It is a spore pathogen belonging to the strongest (Anthrax, Streptococcus, Tetanus, Malignant Drops, etc.), and the microorganisms belonging to the common are classified as microorganisms (Mycobacterium tuberculosis, Staphylococcus aureus, Streptococcus, etc.), and the microorganisms belonging to the weakest (E. , foot-and-mouth disease, swine cholera, Newcastle disease, rabies, Japanese encephalitis, etc.), and those belonging to very weak ones (Hemorrhagic Septic Bacillus Brucella, etc.) can be easily sterilized by fermentation and drying, etc. .

In the change in the resistance of microorganisms over time according to liquid slaked lime disinfection, spore pathogens (anthrax, bacillus anthracis, tetanus, malignant droplet, etc.) were 4.3 CFU in the first week. It was found that from 4 CFU to 1,2 CFU at 5 weeks, normal microorganisms (Mycobacterium tuberculosis, Staphylococcus aureus, Streptococcus, etc.) were reduced from 4.8 CFU in the first week to 0.5 at 5 weeks, and weak microorganisms (E. coli, Don Viruses of single bacteria, foot-and-mouth disease, swine cholera, Newcastle disease, rabies, Japanese encephalitis, etc.) were reduced to 3.9~0.2CFU, and a number of other microorganisms were almost completely killed in the 5th week. The experimental results were as shown in FIG. 3 .

4-2. Corrosion index change using liquid slaked lime

As a result of testing the direct water supplied to the farm, which is the control group, it can be seen that the LR standard is reduced to 0.5 or less. The LR value is decreased due to the increase in strong alkalinity due to the addition of liquid slaked lime. Table 6. shows the change in the corrosive index over time after adding slaked lime step by step.

Corrosion can be judged when the LI index is less than 0, RSI is 6.8 or more, LR is 0.5 or more, and AI is less than 12.

In the evaluation of the corrosiveness of tap water as a control, there was no difference in the corrosive index LI, RSI, LR, and AI according to the change after 24 hours, 48 hours, and 72 hours compared with the initial measured values.

The following results were obtained as a result of a study on the stirring process of the supply hose iron by supplying groundwater supplied from the farm according to the step-by-step input to the liquid slaked lime diluted water. In the control tap water, the concentration was measured to be 0.153 mg/L after 24 hours, and it was found that after 72 hours, it increased 5.3 times to 0.818 mg/L.

Iron powder used for the test contains 90% iron, and it can be observed that iron is dissolved with the naked eye after about 20-30 minutes. After 24 hours, the result of adding liquid slaked lime from 5 mg/L to 20 mg/L in stages showed a decrease of 11.7% to 64.7% from 0.134 mg/L to 0.055 mg/L.

After 48 hours, the concentration was measured at a concentration of 0.537 mg/L of tap water, and as a result of adding liquid slaked lime from 5 mg/L to 20 mg/L in stages, it decreased by 4.1% to 53.1% from 0.533 mg/L to 0.251 mg/L. appeared to be

After 72 hours, the concentration was measured to be 0.816 mg/L of tap water, and the result of adding liquid slaked lime step by step from 55 mg/L to 20 mg/L showed a decrease of 8.9% to 65.4% from 0.745 mg/L to 0.285 mg/L. appeared to be

As a result, it was confirmed that liquid slaked lime is highly effective in controlling corrosion of iron.

In addition, when the corrosive index (LI) of the sample to which 50 mg/L of liquid slaked lime is added is only about -0.71, the corrosive index (LI) of the control tap water is -1.24. Even in the state, corrosion was suppressed, as shown in FIG. 4 .

5. Conclusion

In this experiment, it is suggested that disinfection in livestock farms and exposure of water supplied to the farm and farm floor impair the improvement of the livestock immune system, and the importance of breeding environment management is studied to prevent the occurrence of diseases such as various infectious diseases. I got the same result.

1) As a result of continuous sterilization of liquid slaked lime on the test farm for about 5 weeks, the spore pathogens such as anthrax, emphysema, tetanus, and malignant spp. were initially 4.3 CFU in the change in the resistance of microorganisms by time according to the disinfection. As a result of continuous disinfection with liquid slaked lime, it was found that 4~1,2 CFU was reduced.

2) Microbial strains with moderate resistance, such as Mycobacterium tuberculosis, Staphylococcus aureus, Streptococcus, etc., were reduced to 4.8~0.5CFU in the first week, and weak microorganism strains such as E. It was found that viruses such as those were reduced to 3,9~0,2CFU, and many other harmful microorganisms were almost killed at the 5th week.

3) Corrosion index was measured to be low in winter under the influence of water temperature, confirming that corrosion is better in winter. Corrosion index is better in winter than in summer when the temperature is high. Corrosion index ( LI) was found to be reduced when compared with the iron concentration of -1.24 in tap water corrosive index (LI), which is a control, even when it is about -0.71.

4) In this experiment, when corrosiveness was tested by periodically or stepwise diluting liquid slaked lime for livestock farming, the most appropriate injection amount of liquid slaked lime was 15 mg/L, and the alkalinity according to the injection concentration was 67 mg CaCo3/L, and the pH value was 7,8 appeared.

5) Through this experiment, more in-depth research is needed from a preventive point of view on infectious diseases of livestock such as swine fever, which is close to a national disaster, and liquid slaked lime can be used for the death and prevention of various strains inhabiting the farm. It was found that further research is needed.
