Description

[Technical Field]

[0001] The present invention relates to an infectious organism removal and contaminated breeding water real-time disinfection system for aquatic organism infectious disease prevention measures, which separates infectious disease-infected aquaculture objects and their dead bodies (hereinafter collectively referred to as infectious organisms) from breeding water in aquaculture farms where an aquatic organism infectious disease has occurred, sterilizes and disinfects the pathogen-contaminated breeding water, and then discharges it outside the aquaculture farm. [Background technology]

[0002] Generally, in land-based indoor farms or outdoor farms on land, such as embankment farms along coastlines, a large number of farmed organisms are raised in a limited area at high density, so even if a few individuals become infected with an infectious disease, the disease can quickly spread to all individuals in the tank, resulting in mass mortality of the farmed organisms. One typical example is acute hepatopancreatic necrosis disease (AHPND), in which Vibrio bacteria carrying a specific toxin gene attack the hepatopancreas of shrimp.

[0003] AHPND is an infectious disease that causes major damage to the shrimp farming industry worldwide, with annual damages amounting to approximately 5 billion dollars. There are approximately 600 shrimp farms in Korea, with double-bank farms accounting for more than 80% of them. Recently, at an embankment farm in Sinan County, South Jeolla Province, approximately 70% of the farmed shrimp died due to AHPND infection, resulting in damages of 12 tons and 200 million won.

[0004] Including the AHPND, the Aquatic Organism Disease Control Act has designated a total of 26 aquatic organism infectious diseases as statutory infectious diseases subject to quarantine measures in Korea, and these measures are being implemented accordingly. However, current quarantine measures are limited to the culling, isolation, and movement restrictions of aquatic organisms infected with the disease, as well as the disinfection of equipment and objects contaminated in the process. As a result, there are insufficient regulations, methods, and detailed guidelines for sterilizing and disinfecting the breeding water contaminated with pathogens along with the infectious organisms, and safely discharging it outside the aquaculture facility.

[0005] In the case of the present applicant, the applicant has previously filed a patent application (patent application no. 33426 in 2016) and received a patent registration (patent no. 10-1728426) for a treatment system that prevents the spread of various diseases and contagious illnesses and environmental pollution caused by infectious organisms by treating infectious organisms collected from aquaculture farms, etc., in a short period of time, at low cost, and with high efficiency in accordance with current quarantine measures, and that goes beyond simple treatment concepts such as burying or incinerating infected organisms and enables the infected organisms to be recycled as high-quality organic fertilizer.

[0006] However, the technical features of the above-mentioned prior application focused on immediately treating infectious organisms that have occurred in fish cage farms installed offshore, making it somewhat unsuitable for application to land-based farms. In addition, the actual treatment targets were limited to infectious organisms in accordance with current quarantine measures, and there was a problem that it could not be used to treat breeding water stored in aquaculture tanks that is contaminated with pathogens along with infectious organisms.

[0007] Due to the above-mentioned factors, land-based aquaculture farms have only been able to collect infected organisms and either landfill or incinerate them, or turn them into fertilizer using a treatment system previously filed by the present applicant. However, breeding water contaminated with pathogens and stored in aquaculture tanks is often released without further treatment, and even then, the treatment method applied has been limited to a simple method of directly pouring a large amount of sterilizing and disinfecting agent into the aquaculture tanks.

[0008] However, if breeding water contaminated with pathogens is released without permission, there is a very high risk of the infectious disease spreading to the various aquatic organisms living in nearby rivers and coastal seas. Furthermore, the method of directly adding large amounts of disinfectant to the breeding water requires considerable time and cost (the cost of culling AHPND-infected shrimp at the Sinan-gun aquaculture farm and sterilizing the breeding water: over 30 million won), and not only does it have a very low actual treatment efficiency, but also poses the problem of the disinfectant components contained in the breeding water flowing into nearby rivers and coastal seas, causing secondary environmental pollution.

[0009] To solve the above-mentioned problems, a treatment system must be provided that can collect and dispose of infectious organisms infected with infectious diseases by landfilling, incineration, or fertilization, and can also sterilize and disinfect the breeding water contaminated with pathogens stored in aquaculture tanks to an environmentally harmless level and safely discharge it outside the aquaculture farm. This system can be installed directly at land-based aquaculture farms, or can be implemented as a mobile quarantine system that can be deployed at land-based aquaculture farms as needed. Summary of the Invention [Problem to be solved by the invention]

[0010] The present invention has been made to meet the above-mentioned requirements, and is a sprut pump or a fish pump. The system uses a main transfer pump such as a main pump to suck and transfer the culture water stored in the aquaculture tank together with infectious organisms to an infectious organism separation tank, where the culture water is separated from the infectious organisms. The culture water is then supplied to a pre-treatment filter and / or skimmer to remove various foreign substances from the culture water, and then supplied to a sterilization device using an ultraviolet lamp, an ozone lamp, a plasma generator, or an electrolysis method to completely remove even pathogens from the culture water. This allows the contaminated culture water stored in the aquaculture tank to be purified and sterilized in a quick, efficient, and economical manner and safely discharged outside the aquaculture facility. This fundamentally prevents the recurrence and spread of aquatic infectious diseases caused by the unauthorized discharge of contaminated culture water, and also prevents unnecessary waste of treatment time and costs due to the direct injection of a large amount of sterilizing agent into the aquaculture tank, as well as secondary environmental pollution caused by the components of the sterilizing agent. The system's main technical objective is to provide an infectious organism removal and real-time disinfection system for aquatic infectious disease prevention measures.

[0011] In addition, the present invention applies a water treatment device using a plasma generator as the sterilization device, and supplies excess ozone gas accumulated inside the sterilization device to a skimmer so that bubbles for capturing and removing foreign matter are generated by the ozone gas. Meanwhile, the rearing water discharged from the sterilization device containing residual ozone gas is temporarily retained in a drainage tank of a predetermined capacity equipped with an ozone filter type exhaust pipe before finally being discharged to the outside. This allows the treatment of pathogens by ozone gas to a certain level in the skimmers and drainage tank before and after the sterilization device, and the sterilization device can be operated in parallel. Another technical objective is to further maximize the purification of the culture water and the sterilization and disinfection functions of the pathogens, while minimizing the ozone gas concentration in the culture water that is finally discharged. Another technical objective is to use an aspirator equipped with a dustpan-type intake duct with an adjustable height and a scale bar for measuring the water level, which is mounted on a receiving plate placed on the bottom of the culture tank, in conjunction with a main transfer pump, to efficiently transfer the culture water and infectious organisms simultaneously via the main transfer pump in accordance with the bottom condition of the culture tank and the stored water level of the culture water, without clogging the transfer pipe.

[0012] Meanwhile, the infectious organism separation tank is composed of the introduction tank for the breeding water and the infected organisms via the main transfer pump, the infectious organism recovery tank on one side, and the breeding water storage tank on the lower side. A zigzag guide tray that is inclined upward and downward using a perforated plate is arranged inside the introduction tank, and the final outlet of the guide tray protrudes toward the recovery tank. Meanwhile, a colander-type recovery tray that can be inserted and removed is arranged inside the recovery tank. This makes it easier and more systematic to separate the breeding water from the infected organisms and to collect (recover) the infected organisms without the infectious organisms excessively gathering and accumulating at the outlet of the recovery tank. Further, an overflow pipe is provided on the storage tank of the infectious organism separation tank to automatically discharge excess breeding water into the aquaculture tank, and a scum collection tube is provided on the outside of the skimmer to prevent unnecessary leakage of untreated contaminated breeding water and floating debris. A drum filter with excellent solid removal function is used together with the skimmer as a pre-treatment filter to more completely remove various foreign substances from the breeding water fed into the sterilization device, thereby minimizing breakdowns or malfunctions of the sterilization device and maximizing its inherent functions and service life. [Means for solving the problem]

[0014] The disinfection system according to the present invention further includes an aspirator connected to the main transfer pump and inserted into the aquaculture tank. The aspirator includes at least two support stands vertically connected to a receiving plate placed on the bottom of the aquaculture tank, a dustpan-shaped suction duct connected to each of the support stands and located on the top of the receiving plate, and a connecting pipe connected to the rear side of the suction duct and assembled to the transfer pipe of the main transfer pump. Each of the support stands is a height-adjustable stand having mounting holes drilled at regular intervals along the height direction, and the suction duct is detachably assembled to each height-adjustable stand so that its height from the receiving plate can be adjusted. A scale bar having a predetermined length is vertically connected to the receiving plate of the aspirator so that the water level of the culture water stored in the aquaculture tank can be measured, and the surface of the scale bar is provided with graduations at regular intervals.

[0015] The infectious organism separation tank includes an introduction tank connected to a transfer pipe extending from a main transfer pump and into which infectious organisms are introduced together with the breeding water; a recovery tank disposed on one side of the introduction tank for collecting the infectious organisms; and a storage tank disposed below the introduction tank and the recovery tank for storing the breeding water separated from the infectious organisms. The introduction tank is installed to have a bottom opening communicating with the storage tank, an outlet for infectious organisms provided in the wall on the recovery tank side, and a sealed top surface. A guide tray serving as a partition-type perforated plate for guiding infectious organisms to the outlet on the recovery tank side is installed inside the introduction tank. The recovery tank is installed to communicate with the storage tank via a bottom surface shaped like a perforated partition plate with its top surface open. A supply pipe for supplying the breeding water separated from the infectious organisms to a pretreatment mechanism is connected to the lower part of the storage tank. The transfer pipe is connected to the upper end of the front wall of the introduction tank, and the outlet for the infectious organisms on the recovery tank side is provided at the center of the rear wall of the introduction tank, while the recovery tank is arranged at the rear of the introduction tank to have a height corresponding to the outlet for the infectious organisms. The guide tray includes a main tray installed at a downward incline from the inner surface of the front wall of the introduction tank corresponding to the lower part of the transfer pipe toward the infectious organism outlet, and an auxiliary tray installed at a downward incline from the inner surface of the rear wall of the introduction tank corresponding to the upper part of the infectious organism outlet to the upper center of the main tray. The main tray and auxiliary tray are provided with side walls of a predetermined height on the left and right sides of a partition-type perforated plate, and the lower end of the main tray protrudes a predetermined length toward the recovery tank by penetrating the outlet for infectious organisms in the lower wall.

[0016] In addition, a colander-type collection tray for storing infectious organisms and discharging water is inserted inside the collection tank, and a storage opening is formed on one side wall of the collection tank for lateral insertion and removal of the collection tray. An overflow pipe is connected to the upper part of the storage tank for discharging excess rearing water stored separately from infectious organisms into the aquaculture tank, and the amount of rearing water discharged through the overflow pipe is at least 1.5 times the amount of rearing water discharged through the supply pipe at the lower part of the storage tank. The pre-treatment filter is a cylindrical filtration filter rotatable around an axis inside a filter casing. The drum filter is inserted into the tank and has a cleaning water injection pipe installed inside the filter casing corresponding to the upper side of the filter. The breeding water supplied to the drum filter from the storage tank of the infectious organism separation tank is first poured into the internal space of the filter, and then passed through the filter to be stored inside the filter casing and supplied to a skimmer or a sterilization device. A scum collection tube is installed outside the skimmer to collect scum that is captured in air bubbles and discharged to the outside through the upper end of the skimmer, and a pipe with a drain valve is connected to the lower end of the collection tube.

[0017] The sterilization and disinfection device includes a reaction tank for storing breeding water supplied through a pretreatment mechanism, an apparatus casing installed on the top of the cover plate of the reaction tank, a control unit installed inside the apparatus casing, and a plasma generator connected to the control unit and extending through the cover plate of the reaction tank to the inside lower side of the reaction tank. A supply pipe for breeding water that has passed through the pretreatment mechanism is connected to one side of the reaction tank, and a supply pipe for discharging breeding water that has been sterilized and disinfected by the plasma generator to the outside of the reaction tank is connected to the other side of the reaction tank. The injection tube is connected to the top end of the reaction tank. a plasma generator having a discharge electrode and a ground electrode respectively installed inside and outside a dielectric tube, and a reaction space for generating ozone gas between the dielectric tube and the discharge electrode; the discharge electrode and the ground electrode are connected to a control unit via an insulating cap provided on an upper part of a cover plate of the reaction vessel; an air pump is installed inside or outside a casing of the device, and an air injection pipe extending from the air pump is installed to communicate with the reaction space between the dielectric tube and the discharge electrode via an insulating cap of the plasma generator. [Effects of the Invention]

[0018] According to the present invention described above, the culture water stored in the aquaculture tank in a state of being contaminated with pathogens along with infectious organisms infected with an infectious disease is sucked and transferred by the main transfer pump together with the infectious organisms, and is temporarily separated and stored in the infectious organism separation tank. The culture water is then supplied to a pre-treatment filter and / or skimmer to remove various foreign substances from the culture water, and then supplied to a sterilization device using an ultraviolet lamp, an ozone lamp, a plasma generator, or an electrolysis method, etc., thereby achieving the effect of completely removing even the pathogens from the culture water.

[0019] As a result, contaminated breeding water stored in the aquaculture tanks can be purified and sterilized in a quicker, more efficient, and more economical way, and then safely discharged outside the aquaculture farm. Meanwhile, the infectious organisms separated from the breeding water in the infectious organism separation tank can be collected (recovered) separately and landfilled, incinerated, or converted into fertilizer. This fundamentally prevents the recurrence and spread of aquatic infectious diseases caused by the unauthorized discharge of breeding water contaminated with pathogens, and also prevents unnecessary waste of processing time and costs caused by directly adding large amounts of sterilizing and disinfecting agents to the aquaculture tanks, as well as secondary environmental pollution caused by the ingredients of the sterilizing and disinfecting agents.

[0020] In particular, when using the plasma generator-based sterilization device, excess ozone gas is supplied to the skimmer to create bubbles for capturing foreign matter, and the breeding water discharged from the sterilization device containing residual ozone gas is temporarily retained in a drainage tank equipped with an ozone filter exhaust pipe before being finally discharged to the outside. This allows a certain level of pathogen treatment by ozone gas to be performed in parallel in the skimmer and drainage tank before and after the sterilization device, thereby further maximizing the sterilization function of the sterilization device to purify the breeding water and sterilize pathogens, and minimizing the ozone gas concentration in the breeding water finally discharged.

[0021] In addition, when the aspirator having the above-described structure is used in connection with a main transfer pump, the simultaneous transfer of the breeding water and infected organisms by the main transfer pump can be performed more efficiently in accordance with the bottom condition of the aquaculture tank and the level of the breeding water stored therein, without clogging of the transfer pipe. When the infectious organism separation tank having the above-described structure is applied, the separation of the breeding water and infected organisms and the collection (recovery) of the infected organisms can be performed more easily, systematically, and reliably, without the infectious organisms excessively gathering and accumulating at the outlet side.

[0022] Additionally, the overflow pipe installed in the storage tank of the infectious organism separation tank and the scum collection tube installed outside the skimmer can be used to prevent unnecessary leakage of untreated contaminated breeding water and floating debris. By using a drum filter with excellent solid removal function together with the skimmer as a pre-treatment filter, various foreign substances in the breeding water fed into the sterilization device can be more completely removed, minimizing breakdowns and malfunctions of the sterilization device and maximizing its inherent functions and service life.

[0024] The present invention will now be described in detail with reference to the accompanying drawings.

[0025] As shown in Figure 1, the infectious organism removal and real-time disinfection treatment system for contaminated breeding water for aquatic organism infectious disease prevention measures of the present invention is composed mainly of a main transfer pump 3 that sucks and transfers the breeding water stored in the aquaculture tank 2 together with the infectious organisms through a transfer pipe 4, an infectious organism separation tank 20 that separates the breeding water supplied through the transfer pipe 4 of the main transfer pump 3 from the infectious organisms and stores it, a pre-treatment mechanism that removes various foreign substances from the breeding water supplied through the infectious organism separation tank 20, and a sterilization and disinfection device 50 that sterilizes and disinfects the breeding water supplied through the pre-treatment mechanism.

[0026] The main transfer pump 3 may be any type of pump mechanism that can suck in and transfer infected organisms together with the breeding water without clogging, and is installed so that its position can be adjusted using a caster-equipped carrier 3a in the drawing. Typical examples include the well-known sprut pump and fish pump. The sprut pump is a centrifugal pump with spiral vanes formed on the impeller and is used to discharge sludge or solids along with sewage water, etc., and the fish pump uses negative pressure (pressure below atmospheric pressure) generated by the process of spraying breeding water at high pressure (high speed) from the first suction pipe through a jet nozzle to suck in fish into the second suction pipe and then transfer them together with the breeding water.

[0027] Representative examples of the pre-treatment mechanism include a pre-treatment filter 30 for removing solids from the breeding water and a skimmer 40 for trapping proteins and harmful gas components in the breeding water as bubbles to remove them. Either the pre-treatment filter 30 or the skimmer 40 may be used depending on the amount and type of foreign matter contained in the breeding water, but it is preferable to use both the pre-treatment filter 30 and the skimmer 40 whenever possible. The pre-treatment filter 30 may be any known type of water treatment filter, and since a wide variety of types of skimmers 40 are known technologies used in the water treatment field, only a representative example applicable to the present invention will be briefly mentioned below.

[0028] In addition, in the case of the sterilization and disinfection device 50, which is responsible for the core water treatment in the present invention, an appropriate type can be selected from existing water treatment devices that use ultraviolet lamps, ozone lamps, or plasma generators, or that use electrolysis. However, when taking into consideration all of the sterilization and disinfection performance of the breeding water, the treatment time, and the space (volume) and load required to install the device, the sterilization and disinfection device 50 using a plasma generator can be considered the most reasonable. However, it should be made clear at the outset that any type of water treatment device can be used as the sterilization and disinfection device 50 as long as it can sterilize and disinfect pathogens contained in the breeding water safely at a high level.

[0029] More specifically, to enable the simultaneous suction and transfer of the culture water and infectious organisms using the main transfer pump 3 to be performed more efficiently in accordance with the state of the bottom of the aquaculture tank 2 and the level of the culture water, an aspirator 10 connected to the main transfer pump 3 is further installed inside the aquaculture tank 2, and the infectious organism separation tank 20 is equipped with an overflow pipe 7 that automatically discharges only the excess amount into the aquaculture tank 2 when the amount of culture water separated from the infectious organisms exceeds the treatment standard value, thereby preventing unnecessary leakage of untreated contaminated culture water to the outside.

[0030] In addition, when the sterilization and disinfection device 50 using the plasma generator is used, excess ozone gas accumulated inside the sterilization and disinfection device 50 is supplied to the skimmer 40 through the injection tube 8, thereby generating bubbles for capturing foreign matter with the ozone gas. Meanwhile, the rearing water discharged from the sterilization and disinfection device 50 containing residual ozone gas is temporarily retained in the drainage tank 60 before being finally discharged to the outside, so that the sterilization and disinfection of pathogens by the ozone gas can be performed in parallel to a certain extent in the skimmer 40 and the drainage tank 60 before and after the sterilization and disinfection device 50.

[0031] FIG. 1 shows a typical example in which the disinfection treatment system 1 of the present invention is fixedly installed in a fish farm together with tables 9 for each device, but it is also possible to integrate the entire system from the aspirator 10 to the wastewater tank 60 in a vehicle such as a truck and use this as a mobile quarantine system. Each device from the infectious organism separation tank 20 to the wastewater tank 60 is sequentially connected by a rearing water supply pipe 5, but it is preferable to install a supply pump 6 in parts where it is difficult to supply water by drop using the stored water level of the rearing water, such as the supply pipe 5 connecting the pre-treatment filter 30 and the skimmer 40, and the supply pipe 5 connecting the skimmer 40 and the sterilization and disinfection device 50.

[0032] 2 to 11 show in more detail each device substantially used in the present invention, from the suction device 10 to the wastewater tank 60. The suction device 10, which is inserted into the aquaculture tank 2 while connected to the main transfer pump 3, includes at least two support stands vertically connected to each other on a receiving plate 15 placed on the bottom of the aquaculture tank 2, a dustpan-shaped suction duct 11 connected to each of the support stands and placed on the top of the receiving plate 15, and a connecting pipe 12 connected to the rear side of the suction duct 11 and assembled with the transfer pipe 4 of the main transfer pump 3.

[0033] As described above, the dustpan-shaped suction duct 11 connected to the transfer pipe 4 of the main transfer pump 3 is spaced a certain distance (height) from the bottom of the aquaculture tank 2 by the backing plate 15 and support base. This prevents foreign matter such as feed waste, excrement, and sludge that has settled in large quantities at the bottom of the aquaculture tank 2 from being sucked in all at once through the transfer pipe 4 along with the infectious organisms. Instead, they are mixed with the culture water at an appropriate rate by taking advantage of the suction force of the culture water through the suction duct 11. This prevents clogging of the transfer pipe 4 by foreign matter and infectious organisms at the bottom of the aquaculture tank 2 and allows the treatment load from the infectious organism separation tank 20 to be maintained at an appropriate level.

[0034] More preferably, mounting holes 14 are drilled at regular intervals along the height direction of the support stand, and each support stand is installed as a height adjustment stand 13 for the intake duct 11, and assembly holes (not shown) corresponding to the mounting holes 14 of the height adjustment stand 13 are also formed on the body of the intake duct 11 so that the intake duct 11 can be detachably assembled to each height adjustment stand 13 using assembly means such as bolts so that the height from the support plate 15 can be adjusted.A scale bar 17 of a predetermined length with scales 18 formed at regular intervals so that the water level of the breeding water stored in the aquaculture tank 2 can be grasped is connected vertically to the support plate 15 together with the height adjustment stand 13.

[0035] By applying the above-mentioned method, the position of the intake duct 11 can be easily adjusted to the most suitable position for transferring the culture water and infectious organisms according to the amount of foreign matter accumulated at the bottom of the culture tank 2, the condition of the bottom, and the water level of the culture water stored in the culture tank 2. In addition, the amount of culture water supplied via the main transfer pump 3 can be checked in real time using the scale bar 17, enabling a constant supply treatment cycle of the culture water to match the treatment capacity of the disinfection treatment system 1 according to the present invention, thereby making the simultaneous transfer of the culture water and infectious organisms more efficient.

[0036] In the drawing, the support plate 15 is separated into two, left and right, and the scale bar 17 is installed on the support plate 15 together with the height adjustment base 13 so that they function as support bases for the intake duct 11 in parallel. Two height adjustment bases 13 are installed on one side of the support plate 15 and one on the other side of the support plate 15, and are installed symmetrically with the scale bar 17. The left and right support plates 15, height adjustment bases 13 and scale bar 17 are connected and fixed together by a pair of angle frame type reinforcing bases 16, and the connecting pipe 12 is provided with a pipe connection portion 19 equipped with a flange portion for piping connection to the transfer pipe 4, but such additional structure can be changed as needed.

[0037] Figures 4 and 5 show an infectious organism separation tank 20 used in the present invention, which is composed of an introduction tank 21 connected to a transfer pipe 4 extending from a main transfer pump 3 and into which infectious organisms are introduced together with rearing water, a recovery tank 22 located on one side of the introduction tank 21 (the right side in the drawing) for collecting infectious organisms, and a storage tank 23 located below the introduction tank 21 and the recovery tank 22 for storing rearing water separated from infectious organisms.

[0038] In the drawing, the introduction tank 21 is installed so as to have a bottom opening 21a communicating with the storage tank 23, an outlet for infectious organisms provided in the wall on the recovery tank 22 side, and a sealed upper end surface, and a guide tray 24 as a partition-type perforated plate 25 that guides infectious organisms to the outlet on the recovery tank 22 side is installed inside the introduction tank 21, and the recovery tank 22 is installed so as to communicate with the storage tank 23 through its bottom surface in the form of a perforated partition plate 28 with its upper end surface open, and a supply pipe 5 is connected to the lower part of the storage tank 23 to supply rearing water separated from infectious organisms to the pre-treatment mechanism, and the above-mentioned overflow pipe 7 is connected to the upper part of the storage tank 23.

[0039] More specifically, the transfer pipe 4 is connected to the upper end of the front wall (left side in the drawing) of the introduction tank 21, and the outlet for the infectious organism recovery tank 22 is provided at the center of the rear wall (right side in the drawing) of the introduction tank 21. The recovery tank 22 is arranged at the rear side of the introduction tank 21 so as to have a height corresponding to the outlet for the infectious organisms. The guide tray 24 has a zigzag structure that is alternately inclined vertically, consisting of a main tray installed at a downward incline from the inner surface of the front wall of the introduction tank 21, which corresponds to the bottom of the transfer pipe 4, to the outlet side for the infectious organisms, and an auxiliary tray installed at a downward incline from the inner surface of the rear wall of the introduction tank 21, which corresponds to the top of the outlet for the infectious organisms, to the upper center of the main tray.

[0040] The above-mentioned arrangement structure of the guide tray 24 allows the infectious organisms introduced into the introduction tank 21 along with the rearing water to be dispersed evenly in stages across the auxiliary tray and main tray without excessively gathering and accumulating at the outlet on the recovery tank 22 side, thereby enabling the separation of the rearing water and the infectious organisms to be carried out more systematically and reliably.The main tray and auxiliary tray are preferably provided with side wall portions 26 of a predetermined height on the left and right sides of the partition-type perforated plate 25, and it is preferable that the lower end of the main tray equipped with the side wall portion 26 passes through the outlet for the infectious organisms and protrudes a predetermined length toward the recovery tank 22 side.

[0041] In addition, it is preferable to insert a sieve-type collection tray 27 provided with drainage holes 27a inside the collection tank 22 for storing infected organisms and draining moisture. It is preferable that the collection tray 27 is made to a size such that its upper edge is close to or in contact with the inner surface of the collection tank 22 to prevent infected organisms from falling out of the collection tray 27. It is also preferable to form a storage opening 22a in one side (right side in the drawing) wall of the collection tank 22 that allows the collection tray 27 to be inserted and pulled out sideways so that the infected organisms separated from the rearing water can be collected together with the collection tray 27.

[0042] In addition, it is preferable to install a spacer 28a on the upper side of the perforated partition plate 28 that forms the bottom of the collection tank 22 to separate the collection tray 27 and the perforated partition plate 28 in order to ensure smooth dehydration of the infectious organisms.If necessary, the spacer 28a may be further provided with the function of a digital scale (weighing scale) that can measure the weight of the infectious organisms.This makes it possible to temporarily stop operation of the disinfection treatment system 1 according to the present invention when infectious organisms of a weight that reaches a set value are collected inside the collection tray 27, and then restart the system when the collection tray 27 emptied of the infectious organisms or a new collection tray 27 is loaded again.

[0043] In the drawing, the outer frame 20a, which acts as a reinforcing angle frame, is assembled and installed vertically along the outer corners of the infectious organism separation tank 20, using the storage tank 23 as a base. Support legs 29 for the infectious organism separation tank 20 are installed at the lower end of each outer frame 20a. The overflow pipes 7 are connected to the storage tank 23 as a total of two piping lines, and the supply pipe 5 is connected to the storage tank 23 as a single piping line. This is to ensure that the discharge volume of culture water through the overflow pipe 7 is greater than the discharge volume of culture water through the supply pipe 5, preferably by a minimum of 1.5 times to a maximum of 3 times, in order to fundamentally prevent the water level in the storage tank 23 from exceeding the standard value and leaking outside the infectious organism separation tank 20.

[0044] It should be made clear that the structure of the infectious organism separation tank 20 described above corresponds to the optimum embodiment applicable to the present invention, and that any structure of the infectious organism separation tank 20 may be applied as long as it satisfies the condition of separating and storing separately the rearing water supplied together with infectious organisms via the main transfer pump 3 from the infectious organisms. The simplest application example is one in which only the recovery tank 22 is placed on top of the storage tank 23, and the recovery tray 27 or a landing net or four-handle net-like recovery mechanism with handles can be inserted inside the recovery tank 22.

[0045] Figures 6 and 7 show an example of a pretreatment filter 30 used in the present invention, which is a known drum filter in which a cylindrical filtration filter 34 is inserted so as to be freely rotatable inside a filter casing 31, which serves as a sealed tank supported by a base 32, and a cleaning water injection pipe 39 is installed inside the filter casing 31 corresponding to the upper side of the filtration filter 34.The breeding water supplied to the drum filter from the storage tank 23 of the infectious organism separation tank 20 is first poured into the internal space of the filtration filter 34, and the breeding water stored inside the filter casing 31 after passing through the filtration filter 34 is supplied to the skimmer 40 through a supply pipe 5 equipped with a supply pump 6.

[0046] The filtration filter 34 is attached to the outer surface of the filter frame 33, which is a cylindrical framework frame having a front cover 35 and a rear cover 36. A rotating support shaft 37 that passes through the filter casing 31 with a bearing 37a interposed is installed in the center of the front cover 35 and the rear cover 36. The supply pipe 5 extending from the infectious organism separation tank 20 passes through the rotating support shaft 37 of the front cover 35 with a bearing 37a interposed and extends to the inside of the filter frame 33. A transmission mechanism 38a (a chain and sprocket in the drawing) that is connected to the drive motor 38 is installed at the end of the rotating support shaft 37 of the rear cover 36 so that the filtration filter 34 can rotate axially together with the filter frame 33. Cleaning water spray nozzles 39a are installed at regular intervals in the cleaning water spray pipe 39.

[0047] The detailed configuration of the drum filter described above is also a well-known technology widely known to those skilled in the art. The bearing 37a is preferably a waterproof bearing capable of preventing leakage of the breeding water. The reason why the drum filter is applied as the optimal embodiment of the pre-treatment filter 30 used in the present invention is that it has the most excellent solid matter removal function among various types of water treatment filters, and when used in combination with the skimmer 40, it can more completely remove various foreign matters from the breeding water introduced into the sterilization and disinfection device 50, thereby minimizing breakdowns and malfunctions of the sterilization and disinfection device 50 and maximizing its inherent functions and service life.

[0048] Figure 8 shows an example of a skimmer 40 used in the present invention, in which a scum discharge pipe 46 and a breeding water supply pipe 5 are connected to the upper and lower ends of a cylindrical collection casing 41 of a predetermined height, and a stand pipe 42 of a predetermined height is inserted into the inside of the collection casing 41 in a double-pipe shape. A receiving tube 44 is installed at the lower end of the collection casing 41, and a breeding water supply pipe 5 is connected to the lower end of the stand pipe 42, which runs from the bottom plate 43 of the collection casing 41 through the receiving tube 44 and extends to the sterilization device 50 side.

[0049] Furthermore, the injection tube 8 extends from the sterilization and disinfection device 50 using a plasma generator, penetrates the lower part of the collection casing 41 in a watertight manner, and is inserted to a position adjacent to the stand pipe 42. A known air bubble generator such as an air stone may be inserted instead of the injection tube 8. The air bubble generator is connected to an air pump (not shown) or the like by an air injection tube. A lattice-shaped guide channel 45 is installed at the upper inside of the collection casing 41 between the stand pipe 42 and the discharge pipe 46 so that scum trapped in the air bubbles can be easily separated from the culture water.

[0050] Therefore, the breeding water pumped from the pre-treatment filter 30 into the collection casing 41 first collides with the standpipe 42, and then rises in a spiral around the standpipe 42 together with bubbles generated by ozone gas supplied from the injection tube 8 or bubbles generated by air stones, etc. During this process, organic matter, protein components, and harmful gas components such as ammonia contained in the breeding water, as well as fine solid components not removed by the pre-treatment filter 30, are captured by the bubbles and discharged in the form of scum along the guide channel 45 and the discharge pipe 46, while the breeding water from which foreign matter has been removed is supplied to the sterilization device 50 via the standpipe 42 and the supply pipe 5.

[0051] In addition to the above-described type of skimmer 40, any type of skimmer 40 may be used as long as it can capture various foreign matter contained in the breeding water into air bubbles and remove them in the form of scum. Even when using such a skimmer 40, it is preferable to prevent the scum, which is floating residue discharged from the collection casing 41, from unnecessarily leaking out. Therefore, as shown by phantom lines in Figure 8, a collection tube 47 having a predetermined storage capacity is further installed on the outside of the collection casing 41 corresponding to the lower part of the discharge pipe 46, so that the scum discharged from the skimmer 40 can be stored in the collection tube 47 and then separately processed. For this purpose, a drain pipe 48 equipped with a drain valve 49 is connected to the lower end of the collection tube 47.

[0052] Figures 9 and 10 show a typical example of a sterilization and disinfection apparatus 50 used in the present invention, which is a known water treatment device based on a plasma generator 53. The sterilization and disinfection apparatus 50 includes a reaction tank 52 for storing rearing water supplied through a pretreatment mechanism, an apparatus casing 51 installed on top of the cover plate 52a of the reaction tank 52, a control unit 57 installed inside the apparatus casing 51, and a plasma generator 53 connected to the control unit 57, penetrating the cover plate 52a of the reaction tank 52 and extending to the lower inside of the reaction tank 52. Several to several tens of plasma generators 53 are installed in accordance with the storage capacity (internal volume) of the reaction tank 52.

[0053] Therefore, a supply pipe 5 for breeding water that has been pre-treated is connected to the bottom of one side (left side in Figure 9) of the reaction tank 52, and a supply pipe 5 for discharging breeding water that has been sterilized and disinfected by a plasma generator 53 to the outside is connected to the top of the other side (right side in Figure 9) of the reaction tank 52. An injection tube 8 extends from the top inside the reaction tank 52, which serves as an accumulation space for ozone gas, to the skimmer 40 side, and the part where the end of the injection tube 8 penetrates the wall of the reaction tank 52 is also watertight. If necessary, a small air pump can be installed on the injection tube 8.

[0054] As is well known, the plasma generator 53 has a discharge electrode 54 and a ground electrode 55 installed inside and outside a dielectric tube 56, respectively, and a reaction space 56a for generating ozone gas between the dielectric tube 56 and the discharge electrode 54. The discharge electrode 54 and the ground electrode 55 are connected to a control unit 57 via an insulating cap 53a provided on the top of the cover plate 52a of the reaction vessel 52. An air pump 58 is installed inside or outside the device casing 51, and an air injection pipe 59 extending from the air pump 58 is installed so as to communicate with the reaction space 56a between the dielectric tube 56 and the discharge electrode 54 through the insulating cap 53a of the plasma generator 53. The element designated by reference numeral 58a in the drawing is a support stand for the air pump 58.

[0055] Here, the term "dielectric" has a similar meaning to that of an insulator, but is distinguished from an insulator in that an electrical effect such as dielectric polarization is added. By placing a dielectric tube 56 between a discharge electrode 54 and a ground electrode 55, to which power is applied via a control unit 57, a dielectric polarization phenomenon can be induced between the discharge electrode 54 and the dielectric tube 56. This dielectric polarization phenomenon distributes a large amount of electric charge on the discharge electrode 54, and oxygen (O2) in the air introduced by an air pump 58 into a reaction space 56a between the discharge electrode 54 and the dielectric tube 56 reacts with the large amount of electric charge to generate a large amount of activated ozone gas (O3). The generated ozone gas escapes through the opening at the bottom of the dielectric tube 56 and diffuses in the form of fine bubbles through the breeding water stored in the reaction tank 52, thereby sterilizing and disinfecting pathogens in the breeding water.

[0056] As described above, the generation of ozone gas using the plasma generator 53 and the process of sterilizing and disinfecting pathogens are well-known technologies in the field of water treatment, and therefore further detailed explanations will be omitted. In the case of a sterilization and disinfection device 50 using an ultraviolet lamp, an ozone lamp, or an electrolysis method, it may be understood that an ultraviolet lamp, an ozone lamp, or an electrolysis unit is installed instead of the plasma generator 53. In this case, the air pump 58 is not required, and a zigzag flow path adjustment plate or the like may be additionally installed inside the reaction tank 52 to ensure sufficient reaction time (retention time of the breeding water) between the breeding water and the ozone gas.

[0057] FIG. 11 shows an example of a wastewater tank 60 used in the present invention, in which a medium-sized container with a capacity of 1000 L (liters) that is widely used in industrial sites is applied to the wastewater tank 60, but an exhaust pipe 66 equipped with an ozone gas neutralizing filter 67 is additionally installed on the upper surface of the container. As is well known, the wastewater tank 60 as a medium-sized container is fitted with a lid 65 on the upper end and a drain pipe 63 equipped with a drain valve 64 on the lower end of one side, and is inserted into a framework-type storage frame 61 provided with a forklift transport platform 62 at the bottom.

[0058] The exhaust pipe 66 allows ozone gas components degassed from the breeding water stored in the drainage tank 60 to be exhausted to the outside through a neutralization filter 67. A typical example of the neutralization filter 67 is a breathable porous body with an ozone removal layer coated on its surface. A typical example of the ozone removal layer is a mixture layer of activated carbon, titanium dioxide (TiO2), and zeolite (a porous crystal made of silicon and aluminum used as a reaction catalyst). However, any other type of filter or catalyst may be used as long as it is capable of neutralizing or removing ozone gas.

[0059] The reason why the rearing water that has passed through the sterilization and disinfection device 50 is temporarily stored in the drainage tank 60 equipped with the ozone filter type exhaust pipe 66 before being finally discharged is that it is almost impossible to completely dissolve ozone gas in the rearing water inside the reaction tank 52 of the sterilization and disinfection device 50 and reduce the ozone gas concentration in the finally discharged rearing water to zero. Therefore, a certain level (concentration) of ozone gas is always contained in the rearing water that has passed through the sterilization and disinfection device 50, and such ozone gas can also be a factor that has a negative impact on the external environment, so the ozone gas concentration in the finally discharged water is treated to a harmless level.

[0060] In other words, by temporarily storing the rearing water discharged from the sterilization and disinfection device 50 containing residual ozone gas in the drainage tank 60, the rearing water is further sterilized and disinfected by the residual ozone gas, and the residual ozone gas is degassed and neutralized. This further maximizes the sterilization and disinfection function of the rearing water, and minimizes the ozone gas concentration in the finally discharged rearing water. It should be made clear that the drainage tank 60 is not limited to the form shown in Figure 11, and various other types of tank-type containers can be used as long as they can achieve this function.

[0061] According to the present invention having the above-mentioned configuration, the culture water stored in the aquaculture tank 2 in a state of being contaminated with pathogens along with infectious organisms infected with an infectious disease is sucked and transferred together with the infectious organisms by the main transfer pump 3, and is temporarily separated from the infectious organisms and stored in the infectious organism separation tank 20. The culture water is then supplied to the pre-treatment filter 30 and / or skimmer 40 to remove various foreign substances from the culture water, and is then supplied to the sterilization device 50 using an ultraviolet lamp, an ozone lamp, a plasma generator 53, or an electrolysis method, etc., to completely remove even the pathogens from the culture water.

[0062] As a result, the contaminated breeding water stored in the aquaculture tank 2 can be purified and sterilized in a quicker, more efficient, and more economical manner, and then safely discharged outside the aquaculture farm. Meanwhile, the infectious organisms separated from the breeding water in the infectious organism separation tank 20 can be collected (recovered) separately and landfilled, incinerated, or converted into fertilizer. This fundamentally prevents the recurrence and spread of aquatic infectious diseases caused by the unauthorized discharge of breeding water contaminated with pathogens, and also prevents unnecessary waste of processing time and costs due to the direct injection of large amounts of sterilizing and disinfecting agents into the aquaculture tank 2, as well as secondary environmental pollution caused by the components of the sterilizing and disinfecting agents.

[0063] In particular, when using the sterilization device 50 based on the plasma generator 53, excess ozone gas is supplied to the skimmer 40 to generate bubbles for capturing foreign matter, and the breeding water discharged from the sterilization device 50 containing residual ozone gas is temporarily stored in the drainage tank 60 equipped with an ozone filter type exhaust pipe 66 before being finally discharged to the outside. This allows the skimmer 40 and the drainage tank 60 before and after the sterilization device 50 to simultaneously treat pathogens to a certain extent, thereby further maximizing the breeding water purification and pathogen sterilization functions based on the sterilization device 50 and minimizing the ozone gas concentration in the breeding water finally discharged.

[0064] In addition, when the aspirator 10 having the structure shown in Figures 2 and 3 is used in connection with the main transfer pump 3, the simultaneous transfer of the culture water and infected organisms by the main transfer pump 3 can be performed more efficiently without clogging the transfer pipe 4 by adjusting the bottom condition of the aquaculture tank 2 and the water level of the culture water.When the infectious organism separation tank 20 having the structure shown in Figures 4 and 5 is applied, the separation of the culture water and the infectious organisms and the collection (recovery) of the infectious organisms can be performed more easily, systematically, and reliably without the infectious organisms excessively gathering and accumulating at the outlet side.

[0065] Additionally, the overflow pipe 7 installed in the storage tank 23 of the infectious organism separation tank 20 and the scum collection tube 47 installed outside the skimmer 40 can be used to prevent unnecessary leakage of untreated contaminated breeding water and floating debris, and by using a drum filter with excellent solid removal function as the pre-treatment filter 30 together with the skimmer 40, various foreign substances in the breeding water fed into the sterilization device 50 can be more completely removed, minimizing breakdowns or malfunctions of the sterilization device 50 and maximizing its inherent functions and service life.
