Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for preventing livestock and foot and mouth disease,

The present invention relates to a foot-and-mouth disease preventing facility, and more particularly, to an acidic water having a pH of 5.0 or less and an alkaline water having a pH of 11.0 or more from ground water using electrolysis, and spraying an acidic water or alkaline water thereto, The present invention relates to an anti-foot-and-mouth disease prevention facility using electrolysis capable of purifying acidic wastewater or alkaline wastewater collected by falling from a vehicle or the like with alkaline water or acidic water generated in the electrolysis process and discharging it without causing contamination.

Foot-and-mouth disease (FMD) is the first malignant epidemic of the OIE List A Disease (OIE List A Disease) designated by the Office International desEpizooties (OIE) It is a contagious disease, but it occurs in cloven-hoofed animals, such as pigs and sheep's elephants, with rapid rise in body temperature and blisters (vesicles) in the nipple nipples, It is characterized by severe sickness or death.

In order to prevent the transmission of foot-and-mouth disease, we are actively engaged in anti-virus activities without distinguishing between vehicles and livestock farmers.

Conventional sanitary facilities use acidic substances to dissolve by using the characteristics of foot-and-mouth disease, which is rapidly killed when the pH is below 5.0 or above pH 11.0.

Specifically, the foot-and-mouth disease is rapidly killed at pH 5.0 or lower or at pH 11.0 or higher. Therefore, in an area where foot-and-mouth disease has occurred, an acidic chemical such as citric acid or malic acid is used to prevent the spread of foot-and-mouth disease, and an aqueous solution having a pH of 5.0 or less is injected into a vehicle passing the road. In addition, alkaline chemicals such as caustic soda and sodium hypochlorite may be used to make an aqueous solution having a pH of 11.0 or higher.

However, the above-mentioned apparatus has a problem that the pH is still acidic or alkaline when the sprayed aqueous solution remains after disinfection of the vehicle and flows into the river, thereby causing secondary environmental pollution, There is a disadvantage that a person to be sure to drive must be needed in the hazard area. In addition, since it is necessary to purchase an aqueous solution of citric acid or the like at a large cost, there is also an uneconomical problem.

The present invention has been made in order to solve such a disadvantage, and it is an object of the present invention to provide an electrolytic solution which is capable of producing acidic water having a pH of 5.0 or less and alkaline water having a pH of 11.0 or more from ground water and spraying acidic water or alkaline water, The object of the present invention is to provide an anti-foot-and-mouth disease prevention facility using electrolysis capable of purifying acidic wastewater or alkaline wastewater collected by falling from a vehicle or the like with alkaline water or acidic water produced during the electrolysis process and discharging it without causing contamination.

In order to accomplish the above object, the present invention provides a foot-and-mouth disease prevention and prevention system using electrolysis, comprising: an electrolytic bath partitioned by an underground water supply unit and an ion exchange membrane into an anode chamber and a cathode chamber, A first and a second electrodes of different polarities respectively installed in an anode chamber and a cathode chamber of a decomposition tank and electrolyzing groundwater by receiving power, and electrolyzing groundwater introduced into the electrolysis tank to produce acidic water and alkaline water A spraying section for spraying the water and neutralized water generating section and either the acidic water or the alkaline water generated in the anode chamber and the cathode chamber of the electrolytic bath as anti-wastewater to the anti-fouling substance including the vehicle; Collecting the anti-wastewater, and generating the anti-wastewater and the purified water, which are not used as the anti-wastewater By mixing the alkali water or neutralization of acidic waste water in the disinfectant it is characterized in that-part neutralization for neutralizing the waste water disinfectant.

According to the anti-foot-and-mouth disease prevention facility using electrolysis according to the present invention, the anti-wastewater (acidic water or alkaline water) to be disposed of in the solution injected to the vehicle or the like is combined with a solution (alkaline water or acidic water) Because it does not pollute the river water even if natural discharge to the river, it can prevent the secondary environmental pollution by the preventive water.

Since surface roughness of the electrode is less than 0.5 micrometer, surface scaling by metal ions in the groundwater does not occur on the surface of the electrode when electrolyzing water containing a large amount of metallic ions such as groundwater, It is possible to reduce the cost of the system.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a block diagram of a foot-and-mouth disease prevention and prevention facility using electrolysis according to the present invention. FIG.
FIG. 2 is another example of a foot-and-mouth disease prevention and prevention facility using electrolysis according to the present invention. FIG.

As shown in FIG. 1, the foot-and-mouth antifouling preventive facility using electrolysis according to the present invention includes a groundwater supply unit 10 for supplying groundwater, electrolytic water for groundwater, acidic electrolytic water and alkaline electrolytic water (Either acidic water or alkaline water) generated by the neutralizing water generating unit 20, the anti-countermeasures water and the neutralized water generating unit 20 to the anti-protector including the vehicle 1 A spraying unit 30 for spraying the wastewater to be sprayed on the vehicle 1 and collecting the wastewater to be dropped on the vehicle 1, And a neutralization unit 40 for neutralizing the anti-wastewater by mixing the neutralized water (alkaline water or acidic water) generated in the neutralized water generating unit 20 and not used as the anti-wastewater into the anti-wastewater.

The groundwater supply unit 10 includes a groundwater pump 11 installed in an underground water tank for pumping groundwater, a groundwater tank 12 for storing groundwater pumped by the groundwater pump 11, And a groundwater supply pipe 13 for supplying groundwater to the anti-pollutant water and neutralized water generator 20 by an underground water supply pump 15 and an underground water supply pump 15. Livestock farmers, which are the area where foot-and-mouth disease occurs, are able to supply and receive groundwater efficiently. Therefore, by obtaining groundwater at low cost and producing it as a preventive water source, costs for prevention can be reduced.

However, the groundwater may be mixed with foreign matter (particulate matter), and the foreign matter may interfere with the electrolysis, so that the filter 14 for filtering the foreign matter is preferably applied to the groundwater supply system.

The anticorrosive water and neutralized water producing section 20 is composed of an electrolytic bath 21 partitioned into an anode chamber and a cathode chamber by an ion exchange membrane 22 and supplied with groundwater from a groundwater supply pipe 13, (First electrode (+) and second electrode (-)) of different polarities, which are respectively installed in the cathode chamber and are supplied with power, and are connected to the electrolysis tank (21) And electrolyzes groundwater to produce acidic and alkaline water.

Acidic water and alkaline water can be used as anti-wastewater with a pH of less than 5.0 and a pH of 11.0 or higher, respectively. In the figure, the acidic water and the alkaline water are used as neutralizing water and alkaline water, respectively. However, And alkaline water may be used as the antifouling water and the other one may be used as the neutralizing water.

An acidic water tank 25 and an alkaline water tank 26 may be applied to store the acidic and alkaline water generated in the anode chamber and the cathode chamber of the electrolytic bath 21, respectively.

A pH meter for measuring the pH value of the acidic water and the alkaline water can be provided since it is judged whether or not the acidic water and alkaline water produced in the anode chamber and the cathode chamber of the electrolytic bath 21 can be sterilized. The pH meter measures the pH value of the acidic water and the alkaline water in real time, and the controller controls the controller so that the acidic water is supplied to the sprayer 30 only when the present pH value is below the reference value (for example, pH 5.0) Control the acidic water supply system.

Groundwater, which is the starting material of the water and the neutralization water, is advantageous in that it can be purchased at a low cost. However, metallic ions such as calcium, magnesium, and potassium are dissolved in a large amount. It has a disadvantage that it can not be used for a long time because the electric conductivity is lowered by attaching to scale.

More specifically, the phenomenon that metal ions adhere to the surface of the electrode at the time of electrolysis is associated with the surface roughness average of the electrode.

Until now, the electrode used for electrolysis has generated OH Radical on the anode when electrolysis, resulting in a strong oxidizing action, so that all metals except platinum-based metal are oxidized. Therefore, platinum-based metal is coated on the surface of metal such as titanium or stainless steel Since the method of coating the platinum-based metal is an electroplating method, since the surface of the metal such as titanium or stainless steel is roughly processed for electroplating and the platinum-based metal is electroplated, Is 2.0 micrometers or more. However, if the surface average roughness is 2.0 micrometers or more by conventional electroplating, there is a disadvantage that a large amount of scale adheres to the electrode.

The electrode of the present invention is manufactured by using a high vacuum deposition method to electrolyze groundwater containing a large amount of metallic ions such as calcium, magnesium, potassium, etc. with an average roughness average of 0.5 micrometer or less (0.1 to 0.5 micrometer) (Surface roughness: height between the valley of the coated precious metal from the surface of the electrode base material (iron, titanium, etc.) and the top of the ridge)

The surface roughness of the electrode according to the present invention is determined on the basis of the following.

Table 1 below shows the water quality composition table of the groundwater used in the electrolysis test (unit: mg / L)

Table 2 shows the results of electrolysis (electrolysis for 100 hours) with different surface roughness electrodes placed in the groundwater.

The sprayer 30 is connected to the anode chamber of the electrolytic bath 21 or the acidic water stored in the acidic water tank 25 which is described as being connected only to the anode chamber or the acidic water tank 25 And supplies the water to the vehicle 1. The water supply pump 32 supplies the water to be pumped by the water supply pump 31 and the water supply pump 31 and the water supply pipe 32, And a plurality of nozzles 33 for spraying the cleansing water supplied through the nozzle.

In the drawing, the anti-pollutant supply pipe 32 and the nozzle 33 are designed to fit the vehicle 1, that is, they can be variously changed according to the shape, structure, size,

The nozzle 33 is preferably sprayed only during the passage of the vehicle 1 when the object to be avoided is the vehicle 1. For example, And when the vehicle 1 approaches the vehicle 1, the anti-pollution water pump 31 is activated to spray the anti-pollution water, or alternatively, the nozzle 33 can be opened and closed to open and close the nozzle 33 So that the anti-breakdown water is sprayed.

The neutralization unit 40 neutralizes the anti-wastewater discharged from the vehicle 1 after being sprayed onto the vehicle 1 (acidity away from the vehicle 1) so as to be naturally discharged. Particularly, And the alkaline water generated in the neutralized water generating unit 20 is used as neutralized water. That is, the alkaline water produced in the neutralized water generating unit 20 is largely composed of a collecting unit for the wastewater, a neutralized water supplying unit, and a neutralizing tank.

Although not shown in the drawing, the collecting section of the anti-wastewater is not limited to the one shown in Fig. 1, but the anti-wastewater which is formed at the bottom or side of the anti-fouling space through which the vehicle 1 passes, It can be formed in any structure.

The neutralized water supply section is composed of a preventive water and a neutralized water supply pipe 41 connected to the negative electrode chamber or alkaline water tank 26 of the neutralized water generating section 20 to supply alkaline water to the neutralized water.

The neutralization tank 42 is a structure having a space for storing the anti-wastewater and the neutralized water therein. The neutralization tank 42 is formed in the form of a water channel so as to increase the neutralization efficiency and discharge the water, 41) are connected to each other to neutralize the wastewater by mixing the wastewater with the neutralized water.

In the neutralization tank 42, the treated water neutralized by the anti-wastewater and the neutralized water is generated. Since the treated water can be discharged without any neutralization, the neutralization tank 42 is connected to the surrounding sewage system or river.

A pH meter and a valve may be configured in the neutralization tank 42 so as to discharge the neutralized water when the pH value of the treated water is neutralized so as not to contaminate the river water.

FIG. 2 shows an example in which the electrolytic water supply unit 50 for mixing the electrolytic water in the ground water is included in order to increase the efficiency of electrolysis by the sanitizing water and neutralization water generator 20.

The electrolyte supply part 50 includes an electrolyte tank 51 for storing all the electrolytes capable of increasing the electrical conductivity of groundwater such as sodium chloride (NaCl) or caustic soda (NaOH), an electrolytic solution supplying electrolytic solution stored in the electrolytic tank 51 to groundwater And a supply pipe 52. The electrolytic water supply pipe 52 is connected to the ground water supply pipe 53, for example, and supplies the electrolytic water before the ground water is supplied to the cleansing water and the neutralized water generating unit 20.

The electrolyte supply pipe 52 is configured to be opened and closed through a valve so that the electrolyte can be selectively used as needed.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments.

The operation of the anti-foot-and-mouth disease prevention facility using electrolysis according to the present invention is as follows.

1. Groundwater supply.

The groundwater pump 11 is stored in the groundwater tank 12 by pumping the groundwater from the groundwater tank. That is, irrespective of the spraying of the preventive water, the ground water pump 11 is caused to store a certain amount of ground water in the ground water tank 12 to smooth the supply and demand of the irrigation water.

The groundwater stored in the groundwater tank 12 is pumped from the groundwater tank 12 to the groundwater supply pipe 13 by the pumping of the groundwater supply pump 15 and is transported along the groundwater supply pipe 13, The foreign matter is filtered. The groundwater from which foreign matter has been removed is supplied to the electrolytic bath 21 of the preventive water and neutralized water generating unit 20. In electrolysis, it is preferable to perform electrolysis only from ground water without external input. However, when electrolysis is difficult due to low electric conductivity, adding a small amount of electrolyte enables efficient electrolysis to proceed. 0.3 to 1.0% by weight, preferably 0.5% by weight, based on the ground water is added to the ground water (the lower concentration of the additive is less effective in improving the electric conductivity and the electrolytic reaction in the high concentration is increased but the harmful chlorine gas Because of the possibility of

When the electrolyte supply part (50) is applied, the ground water is mixed with the electrolytic solution and supplied to the electrolytic bath (21).

2. Generation of neutralization water and neutralization water.

The groundwater introduced into the electrolytic bath 21 is generated as electrolytic water and alkaline water through electrolysis of the first and second electrodes 23 and 24 so that the acidic water is collected in the anode chamber and the alkaline water is collected in the cathode chamber.

The acidic water and the alkaline water are stored in the acidic water tank 25 and the alkaline water tank 26, respectively. Here, the acidic water is an antiseptic water and the alkaline water is neutralized water.

3. Spraying water.

The sanitary water (acidic water) stored in the acidic water tank 25 is pumped through the sanitary water pump 31 to be supplied to the sanitary water supply pipe 32 and then sprayed onto the vehicle 1 through the plurality of nozzles 33 . In this process, the foot-and-mouth disease virus in the vehicle 1 is killed by the preventive water.

4. Avoid neutralization.

The neutralized water (alkaline water) stored in the alkaline water tank 26 is supplied to the neutralized water supply pipe 41 through the neutralization tank 42. The neutralized water discharged from the nozzle 33 flows into the neutralization tank 42, To the neutralization tank (42). Therefore, in the neutralization tank 42, the acidic destructive wastewater is neutralized by alkaline water to generate neutral treated water, and the neutral treated water is naturally discharged to a river or a sewer system.

The basic operation according to the present invention has been described so far, and the present invention can be performed both manually and automatically. For example, automatic pumping of groundwater, neutralization of the wastewater and neutralization of the wastewater are automatically performed from the pumping of the groundwater, and the controller receives the pH value of the wastewater and alkaline water from the pH meter to control the electrolysis, And controls the discharge of the treated water based on the pH value of the treated water in the neutralization tank.
