Abstract

The present invention relates to an economical waterway-type bio-secure aquaculture method and a system using the method, wherein harmful organisms and pathogenic microorganisms present in natural fresh and sea water are completely destroyed by electrolysis or by generating oxidants using ozone such that disinfected water is used for aquaculture. The present invention does not employ costly sealed backwash filters nor require an electrolysis tank and an ozone diffuser to be installed in an inflow pipeline in order to filter solid impurities that would interfere with the electrolysis tank and ozone diffuser, but instead, the system of the present invention first pumps water into an upper part of a first chamber comprising 2-8 chambers for continuous-flow disinfection and neutralization treatments, and then filters the water using an inexpensive simple filter in a water passage of the first chamber, so the water passes through the electrolysis tank or ozone diffuser after removing the solid impurities to complete the disinfection process. Accordingly, the present invention provides an inexpensive method for providing bio-security in a water-type bio-secure aquaculture method and an aquaculture system utilizing the same.

Description

{Bio-security aquaculture process by waterway type and its system}

The present invention relates to a method and apparatus for economical waterway bio-security, and more particularly, to a method and apparatus for economical waterway bio-security, and more particularly, In order to remove the obstacles to the electrolytic bath and the ozone dissolver existing in seawater and fresh water in the aquaculture using sterilized aquaculture water that has been completely killed and neutralized, an expensive closed backwash filter and an electrolysis tank And an ozone dissolver is not installed in the inlet pipeline but is first pumped to the top of the first chamber for continuous water sterilization and neutralization treatment consisting of 2-8 chambers, To filter the solids and then to pass through an electrolytic bath or an ozone dissolver To a biosecurity biosecurity method that enables a biosecurity state in a very economical way by performing a sterilization process, and to aquaculture apparatus employing such a method.

Freshwater and seawater have been eutrophicated by various wastewater discharged from the land, and there are various pathogenic microorganisms such as viruses, bacteria and parasites that cause diseases to fishes and humans, and the number of dead fishes of the aquatic organisms continues to increase, exceeding 40% Statistical data are available. The number of cases of food poisoning is on the rise when aquatic organisms are ingested by means of sashimi and sushi.

In the past, it was not a distinction between aquaculture and natural (wild) marine creatures. Even though it was a fresh live fish, when it was eaten raw with sashimi or sushi, it occasionally caused vibrio septicemia. Recently, food poisoning caused by vomiting and abdominal pain caused by parasite called Kudoa septempuntata The case is also increasing, and it is often found that when the live fish is caught, the muscle flesh is soon retreated by parasites such as Kudoa lateolabracis and Kudoa thyrsite.

For this reason, the global aquaculture industry has created a system that completely eliminates or eliminates all pathogenic microorganisms that are harmful to fish and marine life in the freshwater and seawater of the natural ecosystem and prevents harmful microorganisms in the natural ecosystem from entering the fish farm. For example, an economical method of removing or killing pathogenic microorganisms for a large number of aquaculture yields of 3,600 m ³ / h (5 m ³ / min) per 5000 m² of water area I can not propose it properly.

Specifically, a method for treating aquaculture water has been proposed in most aquaculture countries, mainly in Europe, such as Norway, where advanced aquaculture is based. In such advanced countries, (NH ₃ ) secreted by the aquatic organisms in the gills, manure and micro-contamination, such as feed residue. As a method of treating substances, various microorganisms such as Nitro-somonas and Nitro-bacteria are added to various bio-filters to decompose them into nitrous acid and nitric acid, and to the denitrification by RAS (recycling aquaculture system) (Biofloc) method, which has been developed by the present inventors.

However, this aquaculture treatment method can be applied to some species such as tilapia, eel, carp, salmon, and shrimp that are not sensitive to ammonia nitrogen (NH ₃ -N), nitrite nitrogen (NO ₂ -N) Most of the growing aquatic organisms have a high risk of mass mortality and high cost of facilities and maintenance expenses. In case of infestation with parasites such as Scuticociliate, Trichodina, and Baitiao during the process of circulation filtration, There is a fatal problem that there is a risk of occurrence of mass mortality.

The present invention provides a method of using a sterilized aquaculture water which completely solves the above drawbacks and which can kill whole pathogenic microorganisms causing fish diseases and diseases to the human body at a low cost and fundamentally and fundamentally. Korean Patent No. 10-1498990. Here, the problems of the conventional various prior arts are solved, and a highly effective form method is proposed.

In addition, Korean Patent No. 10-1547566 proposes a sterilized water aquaculture system using an electrolytic method by further improving the existing sterilization aquaculture method.

These style methods are evaluated in a very progressive way, and there is no problem in practical use in normal cases. However, this improved method of preparation provides a very efficient method of preparation and a sterilized water aquaculture system, but it does not contain suspended solids such as algae in the aquaculture water supplied, or, in particular, There is no specific solution to the problem that the microbes are not sterilized properly when the foreign substance is contained in a large amount.

In order to solve this problem, there is an uneconomical problem in that it is impossible to apply the filtration process to the filtration equipment so that it can not be practically used when the filtration process is performed prior to injection of culture water.

In this connection, Korean Patent Registration No. 10-1249733 discloses a seawater supply device for supplying seawater for fish culture, comprising: a seawater supply unit for supplying seawater at a predetermined flow rate; An electrolysis unit for electrolyzing seawater supplied by the seawater supply unit to generate electrolytic water; And a relay storage unit for temporarily storing the seawater that has passed through the electrolysis unit before being supplied to the outside, wherein the electrolysis unit is configured to automatically and repeatedly repeat the operation and the stopping at predetermined time intervals, And the stopping time is adjusted in the range of 1: 2 to 1: 5, and the electrolysis unit maintains the electrolytic water concentration of 0.3 ppm to 0.5 ppm of oxidant, And the electrolytic water is not contained in the electrolytic water, the electrolytic water is operated so that the electrolytic water is not contained in the electrolytic water. And a filtration unit for filtering the seawater supplied from the supply unit to remove foreign matter contained in the seawater It has been proposed.

However, this patent relates to a method of intermittently producing and sterilizing an oxidant by repeating electrification and disconnection in an electrolytic tank. The oxidant concentration of 0.3-0.5 ppm is dangerous for massive death due to the inability to fish fish In the case of such a seawater supply device, as described above, there is a problem in that it requires an expensive backwashing-type filtration facility for each seawater supply pipe for filtration and an excessive power cost is required to operate the same. In addition, when an electrolytic bath is installed in each sea water supply pipe for electrolysis, too much cost is required for the structure of the sea water supply device, which makes economical practical use impossible.

Korean Patent No. 10-1264260 proposes a method of supplying seawater to electrolyze seawater to remove harmful organisms and reduce residual chlorine concentration (Oxidant) by using activated carbon, but in this case, electrolysis If the seawater contains foreign matter such as algae or mud as a subsequent filtration process, it is difficult to control the short (short) and oxidant production of the electrolytic tank and it is necessary to use the activated carbon in an enormous amount, Can not be used at all.

Korean Patent No. 10-1498990 Korean Patent No. 10-1547566 Korean Patent No. 10-1249733 Korean Patent No. 10-1264260

In order to solve the problems of the prior art as described above, the present invention improves the system structure related to filtration and electrolytic treatment of aquaculture water in a conventional aquaculture water treatment method using electrolysis, In order to solve the problem that microbes are not properly sterilized when foreign substances such as suspended solids, typhoons and heavy rainwater are contained in fresh water and seawater, and sterilization mode is enabled by efficient and economical methods and devices The problem is solved.

Therefore, it is an object of the present invention to provide a method and apparatus for aquaculture, which is capable of performing a batch filtration process of aquaculture water in a separate integrated space for aquaculture water, The present invention is to provide a method for forming a waterway bio-security form that can be practically used at a significantly lower cost than that of the prior art.

Another object of the present invention is to provide a method for preventing harmful microbes from being produced by electrolytic treatment or ozone supply even when foreign matter such as muddy water, Thereby enabling sterilization to be effectively performed, thereby providing a sterilized aquaculture water to all weather.

Still another object of the present invention is to provide a waterway bio-security form system designed with a structure suitable for applying the economical bio-security form method.

The present invention also relates to a hydrothermal aquaculture water sterilization system having 2-8 chambers in which aquaculture water is continuously supplied, wherein fresh water or seawater is pumped through a plurality of pipelines to inject the aquaculture water without filtration; A single filtration means provided at one side of the upper portion of the first chamber for collectively performing filtration in a channel where the injected culture water flows, a foreign matter removing means for removing the foreign matter filtered by the filtration means, A culture water filtration processing unit including foreign matter discharge means for collecting and discharging foreign matter; A ceiling portion is formed between the other side of the first chamber and the filtration treatment portion, and an oxidant generator including an electrolytic device assembly or an ozone generator is embedded in the ceiling portion of the first chamber, so that the buried oxidant generator is embedded in the aquaculture water An oxidant generator configured to generate oxidant while moving in contact with the oxidant generator; And a second chamber connected to the first chamber and the lower end by a flow path.

Particularly, the present invention is based on the finding that, in a conventional aquaculture system such as Korean Patent No. 10-1498990, when muddy water occurs in fresh water or seawater due to heavy rain or typhoons, or when suspended matter exists, The COD (Chemical Oxygen Demand) substances contained in the muddy water and suspended solids react with the Total Residual Oxidant (TRO) component to generate the TRO concentration It is possible to prevent the inflow of the pathogenic microorganisms into the aquaculture water without killing the pathogenic microorganisms by lowering the concentration of the pathogenic microorganisms to a level lower than the possible sterilizing and insecticidal concentrations.

As described above, since the TRO concentration is not lowered by the foreign substance, the present invention does not need to increase the concentration more than the sterilization concentration of 0.1 - 7 ppm TRO, and basically prevents the pathogenic microorganisms in the natural environmental water system from entering the aquatic environment in any bad environment such as heavy rain or typhoon By completing the Economical Fundamental Biosecurity Aquaculture System, which is economically viable, farmers can contribute to increasing income by lowering the production cost because of the high survival rate of 95% or more for farmers. Which can not be used for pathogens such as Vibrio bacteria and Kudoa septempuntata as well as Biosafety Fish which does not require the use of antibiotics.

Therefore, the aquatic organisms cultured using the aquaculture method or the aquaculture apparatus according to the present invention can be eaten in the state of fresh fish or fresh products such as sashimi and sushi, even for the elderly and children, thereby contributing greatly to the production of national safety aquatic products, There is an economic and practical effect that can innovate.

Hereinafter, the present invention will be described in more detail as an embodiment.

In general, there is known a technique of appropriately sterilizing the aquaculture by filtration treatment and electrolysis treatment before supplying the aquaculture to a farm, and these techniques are generally used to increase the sterilization and insecticidal effects of seawater, And to provide processed seawater to minimize the amount of seawater. However, these conventional techniques are not limited to the electrolytic supply at the inlet of each pipeline in the process of pumping and supplying seawater to the pipeline for the treatment of seawater, or the preliminary filtration and electrolysis of the seawater at the inlet of each pipeline, It is a structure in which each pipeline is equipped with facilities for filtration and electrolysis. Such a structure is known as a closed type or drum filter type filtration type seawater treatment method.

1 is a comparative example in which a conventional filtration type water producing apparatus is applied. In Fig. 1, a filtration type seawater treatment method is shown in which seawater is filtered and electrolyzed and then pumped to a culture water moving chamber through a pipeline, Fig.

However, in the case of filtration and electrolytic treatment of aquaculture water for each of the eight pipelines commonly used on a water surface area of 5000 m ² in a farm where a large amount of seawater should be supplied, the cost of each facility is 80 million KRW -1 100 million won for each pipeline, and 120,000 to 150,000 for each pipeline. Also, since each of the filters requires backwashing, it is very costly to clean the filter. There is an uneconomical problem as necessary.

To improve this point, some pipelines that pump about 1-10% of the aquaculture feed are equipped with filtration and electrolysis facilities, electrolysis to produce high concentration TRO of 1 -70 ppm, and other pipelines The diluted seawater treatment method is applied to obtain the electrolytic treatment effect of 0.1 - 7ppm TRO as a whole by pumping and mixing the supplied seawater as it is without electrolysis.

FIG. 2 is a comparative example in which a conventional dilution type water producing apparatus is applied. Part of the seawater is supplied to the aquaculture tank as shown in FIG. 1 and the other part is pumped into the aquarium A dilution type seawater treatment method of diluting aquaculture water by supplying water, and an apparatus structure in which a system is applied.

However, in such a dilute seawater treatment method, the foreign substances that have been introduced after the dilution of the seawater that has not passed through the filter and the electrolytic bath greatly interfere with the sterilizing action, so that the sterilizing effect is not very good.

Unlike the conventional filtration type seawater treatment method or the dilution type seawater treatment method, the present invention supplies untreated water to the first chamber of the 2-8 chamber structure using various pipelines, The filtration process and the oxidant generation process (electrolysis, ozone dissolution, etc.) are collectively performed in the water channel during the movement of the water in the first chamber, whereby filtration facilities and electrolysis or ozone generation dissolution This is a new concept of marine water treatment method that can be economically put to practical use by greatly saving huge cost due to equipments.

As described above, the present invention relates to a method of sterilizing a water-tank type aquaculture water sterilization system in which aquaculture water is continuously supplied, wherein freshwater or seawater is first pumped through a pipeline without filtration or electrolytic treatment, , A method for collecting sterilized aquaculture water by collecting filtration treatment, oxidative generation, sterilization treatment, and neutralization treatment at a number of the processes of moving the culture water in the first chamber, The present invention relates to a designed hydrofoil biological security device.

According to a preferred embodiment of the present invention, in supplying fresh water or seawater to the chamber, pumping through a plurality of pipelines to supply the aquaculture water to the upper part of the first chamber is performed according to the conventional method. However, unlike the conventional art, in the preferred embodiment of the present invention, filtration and electrolysis are not performed when the ponds are fed through each pipeline.

In general, when supplying freshwater or sea water, a large amount of aquaculture must be supplied. Therefore, it is inevitable to pumplicate using several pipelines, for example, eight pipelines, when the water surface area is 5000 m ³ , and in this process Electrolysis or ozone treatment is conventionally applied prior to pumping the aquaculture water. This is because electrolysis of a large amount of aquaculture water at a time after the culture water is supplied to the chamber does not filtrate suspended matters and muddy water, resulting in a short circuit between the electrodes of the electrolysis tank and the cathode, This is because it is impossible to do so economically. Therefore, in the process of pumping with each pipe, it is a structure that can be pumped while filtering and electrolyzing in advance.

However, in a preferred embodiment of the present invention, this existing configuration is converted into a totally different concept so that all the form numbers are once pumped through several pipelines without any processing and injected into the upper part of the first chamber, And has a new technology structure. In addition, after the filtration step, the water channel in the first chamber is not divided into separate compartments by concrete or the like, and is subjected to the oxidant generation step immediately in the same channel in the first chamber.

Therefore, according to the present invention, the aquaculture water flowing into the upper part of the first chamber is collectively filtered through the filtration compartments divided by one filter net, and then immediately passed to the oxidant generating step to be sterilized, In the step, it is possible to remove the filtered foreign matter.

Therefore, in a preferred embodiment of the present invention, in order to achieve this object, the fresh water or seawater is pumped through the pipeline and is fed into the channel having the aqua filtration means, which is the upper part of the first chamber, without filtration. That is, according to the present invention, since the culture water is injected into the upper part of the first chamber without any pretreatment such as filtration, it is different from the existing technology from the beginning. The first chamber in the form of a moving chamber in which the culture water is supplied and moved is a culture water moving channel, and the water pumped to the upper portion of the first chamber is configured to move naturally from the first chamber to the second chamber after being injected. . The upper portion of the first chamber is preferably provided with filtration means of the novel construction according to the invention.

According to the present invention, the filtration is first carried out for effective disinfection of the aquaculture water after the step of injecting the aquaculture water. Filtration of the aquaculture water is essential. As mentioned in the prior art, Korean Patent No. 10-1498990 discloses a method for accurately sterilizing a desired aquaculture system composed of a plurality of chambers using a water-based continuous sterilization method for sterilizing and insecting aquaculture water by ozone dissolution or electrolysis .

FIG. 3 conceptually illustrates an embodiment of a sterile-type system that includes a culture chamber adapted for use with this conventional method of sterilization.

However, in the case of this conventional sterilization system, when the algae and suspended matter flow in the fresh water or seawater, and the muddy water (muddy water) occurs in the fresh water or seawater due to typhoons and storms, It causes 0.1-7 ppm TRO in fresh water and seawater and passes inside each chamber for 1-28 minutes, which is insufficient sterilization and insecticide problem. The reason is that it ppeolmul (muddy water) and suspended solids flowing in fresh water or sea water surrounding the various pathogenic microorganisms physically sterilized components of TRO (such as _{NaOCl, NaOBr, Br 2, Cl} 2, O 3) is properly in contact with the pathogenic microorganism (COD) components contained in muddy and suspended solids react with the TRO components in the aquaculture water before contact with the microorganisms. Oxidant is added around the muddy water There is a major drawback that the concentration of TRO is lowered at a concentration that can not kill or kill pathogenic microorganisms. However, when the TRO concentration is increased to 7 mg / L (ppm) or more, it is sterilized and insecticidal. However, it is costly to neutralize and sterilize the residual TRO below 0.06 ppm (mg / L) Therefore, the problem that practical use is hard to solve can not be solved.

Therefore, according to the present invention, it is an indispensable process to filter the number of cultivations before generating oxidants in the number of cultivars.

Particularly, in the conventional method, when the suspended solids and muddy water contained in the fresh water and seawater are sent to the electrolysis tank without filtration, the distance between the positive electrode and the negative electrode is narrowed to about 3 mm in the electrolytic apparatus, There is a problem that a high-priced electrode is broken due to a short circuit which is generated between the water and the water, so that it is possible to remove foreign matter of 50-2000 mu m in order to prevent the floating and muddy water from acting as a protective film of a pathogenic microorganism I tried to use various filters. However, in order to remove solid matter of 50-2000 탆 for the entire aquaculture water to be continuously supplied in large quantities, the installation cost and the maintenance cost of the filtration device installed in each of the eight pipelines are too much, It becomes a big obstacle.

In order to solve this problem, a method of preventing the expensive electrode from being broken due to the short circuit of solid material, which is a foreign substance between the anode and the cathode, In the area where the filtration is 2000 μm or the clean underground seawater where there is no suspended matter, only underground seawater is sent to the electrolysis or ozone generating device to generate high concentration TRO of 1 - 70 ppm, A method of indirect dilution (area where underground seawater free of solids of 50 ㎛ or more is removed) or a dilution type (area where no underground seawater is out) by some filtration is used to kill the microorganisms so as to have a concentration of 0.1 -7 ppm TRO. However, this dilution-type seawater treatment method also has a fundamental defect that can not solve the problem that the disinfection effect is greatly deteriorated because the muddy water and the suspended substance act as protective coatings of the pathogenic microorganisms.

Specifically, the sterilization effect of muddy water and suspended solids is greatly reduced when sterilization occurs at 1.5 ppm TRO in aquaculture water.

NaOCl + COD -> concentration of NaOCl in mud (ppm) 40-70% reduction

Concentration of COD -> NaOCl in NaOCl + suspension (ppm) 20-40% reduction

As a result of repeated failures and researches for solving such a problem, the present invention has been made to solve the above-mentioned problems, and it is an object of the present invention to provide a water treatment system, It is very easy, economical and very efficient to perform filtration by collectively filtering with a screen filter of 2000-3000 μm (3mm) on the entrance or the whole surface of the channel where the culture water moves. So that it is possible to effectively filter the foreign matter so that the floating matters and the muddy water do not act as protective films of the pathogenic microorganisms. In particular, in accordance with the present invention, there is provided an apparatus and method for purifying filtered water, comprising a totally unpredictable configuration of pouring the aqueduct water into the upper part of the first chamber without filtration and a new technology arrangement comprising filtration means and oxidant generating means at the top of the first chamber, The present invention provides a new concept of a hydrothermal forming water treatment system which can not be considered in the conventional method because the filtration process and the oxidant generation process can be collectively performed at the upper part of the first chamber,

A feature according to a preferred embodiment of the present invention is that when the filtration is performed in a conventional manner, filtration is required for each of about 8 pipelines, so that a large amount of cost is required for filtration equipment, In order to solve the problem that a lot of costs are incurred due to the addition of devices to be poured, filtration is not performed for each pipeline, and once the aquaculture water is injected into the upper part of the first chamber through a plurality of pipelines without filtration, And a method of collectively filtering the number of cultivated cultivars is newly proposed, thereby achieving the object of the present invention.

For this purpose, according to a preferred embodiment of the present invention, in the process that the culture water pumped without filtration is fed through the water channel from the upper part of the first chamber, the culture water is collectively filtered, And then discharging it to the outside.

According to the preferred method of the present invention, a separate filtration furnace may be additionally provided on the upper part of the first chamber, where the collecting process may be followed by a filtration step, followed by the generation of oxidant.

In addition, according to the preferred method of the present invention, a separate filtration furnace is not additionally provided in the first chamber, and the suspended material is collectively filtered by the filtration means at the upper portion, immediately subjected to the oxidant generating step, May be precipitated in the lower part and discharged, and a method may be employed in which an oxidant is produced after the filtration step is performed in the upper part.

According to the present invention, the filtering step may include a foreign matter discharging step of discharging the filtered foreign matter to the outside.

In the filtration treatment step of the present invention, the aquaculture water is collectively filtered at the upper portion of the first chamber by a single filtration means, and according to a preferred embodiment of the present invention, the filtered foreign matter flows along the surface of the filtration means It can be removed by a method of removing the foreign substance by the method of removing the foreign substance by the method of moving and moving, and by collecting it to the top of the filtration means and discharging it to the outside.

The method of removing foreign matter in the filtration process of the present invention is also characterized in that it is possible to apply a very efficient and simple method which is completely different from the conventional foreign matter removal method.

Conventional filtration or dilution-type seawater treatment methods are structured to filter and electrolyze each of the pipelines before pumping the water using 8 pipelines. Therefore, it is necessary to remove the foreign matter filtered from the filter installed in each pipeline In order to remove the foreign matter, it is necessary to remove the foreign matter filtered by the backwashing method. In other words, in the past, the seawater passing through the filter must be backwashed using a separate washing power so that the foreign matter must be removed by a separate device. Therefore, the apparatus and the structure of the filtration means are complicated and separate power is required for removing the foreign matter In addition, the process of removing foreign matter is complicated.

However, the filtration means according to the present invention is not installed in each pipeline, but can be collectively filtered using a filtration means having, for example, a single filtration filter or a screen- Therefore, it is possible to easily remove the foreign matters filtered by the single filtration means, for example, by using a foreign material removing means for collecting the foreign substances on the screen rotating continuously, such as a conveyor belt, The foreign matter is gathered at the top and can easily be removed to the outside.

Therefore, the filtration means according to the present invention has an economical effect due to the simplicity of the installation of the filtration means and the structure of the equipment compared with the conventional art. Thus, the filtration process is simple in the filtration process, but also the filtration of the filtered foreign substances is very economical and simple. It can be easily removed.

According to a preferred embodiment of the present invention, there is provided an oxidant generating step of collectively performing electrolysis or ozone generation treatment in the channel of the first chamber while moving the collectively filtered water through the water channel, thereby generating residual oxidant in the culture water .

The production of such oxidants is carried out through electrolysis or ozone dissolution for sterilization and insecticide in aquaculture water. In a preferred embodiment of the present invention, an electrolytic apparatus or an ozone generator is used, Unlike electrolysis or ozone dissolution oxidant generation before, electrolyzation and ozone dissolution are carried out immediately after the filtration treatment of the culture water flowing in the upper part of the channel type water channel in which the culture water flows, after the culture water is supplied to the first chamber. The method comprising the steps of: Therefore, it is quite different from generating an oxidant by using electrolysis or the like for each pipeline which pumps the culture water to the first chamber.

As described above, according to a preferred embodiment of the present invention, a method of generating an oxidant by electrolysis or ozone dissolution collectively in the course of aquacultural water movement at the upper part of the channel in the first chamber, not in several pipelines, Therefore, it is not necessary to use a plurality of electrolytic apparatuses or ozone generating apparatuses, and it is possible to effectively generate oxidants by using only one to three, more preferably two or three, apparatuses for generating oxidants.

According to a preferred embodiment of the present invention, in the oxidant generating step, a ceiling portion is formed in an upper part of the first chamber, and an oxidant generating portion composed of an electrolytic device assembly or an ozone generator is buried in the ceiling portion, And an oxidant generation step may be performed in such a manner that an oxidant is generated in the form water transfer channel. Therefore, it is advantageous in that it is possible to generate oxidants very economically and efficiently as compared with the conventional methods.

According to the present invention, when the electrolytic apparatus is used as the oxidant generating apparatus in the oxidant generating step, the conventional dilution type water treatment method passes between the electrode gaps of 3-5 mm only 1-10% of the culture water, The method according to the present invention is characterized in that the whole aquaculture water essentially passes through narrow narrow gaps of 3 -5 mm of the electrolytic bath to produce H ₂ , OH Radical, O ₂ , O ₃ , Cl ₂ , Br ₂ , etc., are sterilized by disinfecting and destroying the protective film which physically covers bacteria and parasites such as mud, soil, and algae. It is sterilized so that pathogenic microorganisms that do not partly die due to low TRO concentration due to direct reaction with COD component contained in the microorganisms and TRO generated from the anode due to excellent insecticidal effect, There is a bigger advantage to be improved, which is how bio-security forms can be fundamentally completed. In other words, in the existing dilution treatment method, even if the TRO concentration in the total amount of water is the same as that of the filtration type or the water channel, there is a possibility that the sterilization can not be partially performed due to a large amount of foreign substances not passing between the anode and the cathode at 3-5 mm intervals And it is difficult to achieve complete biosecurity. In addition, the biofilm can be sufficiently attained because the filtration water passes through the gaps between the anode and the cathode of 3-5 mm of the electrolysis tank. However, the installation cost of the filter and the electrolysis device It will make it difficult to put into practical use many times over.

According to a preferred embodiment of the present invention, there is a sterilization treatment step in which the oxidant-containing aquaculture water is sterilized continuously in a culture water mobile chamber after the oxidant is generated, and a neutralization treatment Treatment step, and sterilized water supply step in which the neutralized sterilized water is injected into aquaculture tank for aquaculture.

In the present invention, the sterilization treatment step after the oxidant fish step, the neutralization treatment step, and the supply step of the sterilization water supply step are the same as those described in Korean Patent No. 10-1498990 and Korean Patent No. 10-1547566, A method of continuously performing sterilization and neutralization in the course of continuous movement of the culture water in the up-and-down alternation can be used as it is.

That is, in the disinfection treatment step for the harmful microorganisms contained in the aquaculture water using the oxidant remaining in the aquaculture water as described above, it is preferable that the sterilization treatment can proceed smoothly while the aquaculture water moves in the aquaculture water transfer chamber. In this case, the sterilization treatment time in the sterilization treatment step is such that all the harmful microorganisms of the fish contained in the aquaculture water are killed, which can be determined by the condition of the aquaculture and the residual amount of the oxidant. The harmful microorganisms sterilized here are various harmful organisms including viruses, bacteria, parasites and algae.

As described above, the aquatic wastewater which has undergone the sterilization treatment step is sterilized but the residual oxidant must be removed. Therefore, in the present invention, sterilized aquaculture water is sent to the neutralization treatment stage for the removal of the oxidant.

In the neutralization step, neutralization agent is added to sterilized aquaculture water to remove residual anoxidant. In this step, the oxydant is removed to a very small amount or practically all of the water is removed. It is to have.

According to the present invention, in the neutralization treatment step, a neutralizing agent is added. Such a neutralization treatment step of the present invention is a method capable of removing an oxidant at low cost and high efficiency.

According to a preferred embodiment of the present invention, in addition to the neutralizing agent addition, a neutralization promoter may additionally be used in the neutralization step.

The sterilization treatment time in the sterilization treatment step can be determined in consideration of the quality of the aquaculture water, the initial residual amount of oxidant, and the like. This sterilization treatment step means the time before the neutralization treatment step is performed, and the sterilization process can be continued for a while by some remaining oxidant even in the neutralization treatment step.

As a neutralizing agent used in the neutralization treatment step, conventional neutralizing agents may be used, and examples thereof include inorganic sulfuric acid sulfuric acid salts, more specifically, sodium thiosulfate, calcium thiosulfate, and the like. At least one selected from among salts, dithionite, ascorbic acid, sodium ascacic acid, cysteine, sulfuric acid gas, sodium sulfite, sodium metabisulfite, potassium metabisulfite, sodium acid sulfite and hydrogen peroxide may be used.

Since the remaining amount of the oxidant in the aquaculture is large, the number of aquaculture has already been subjected to the sterilization treatment step, but the sterilization treatment can be partially performed continuously in the neutralization treatment step. However, in the latter stage of the neutralization treatment step, since the oxidant is almost completely removed and the harmful bacteria against fish such as fish are almost killed, the sterilization treatment is not practically carried out.

As described above, according to the preferred embodiment of the present invention, the sterilization treatment step and the neutralization treatment step are continuously performed, and the sterilization treatment of the aquaculture water can be performed very efficiently even in the point that the sterilization treatment is continued at the initial stage of the neutralization treatment step.

According to the present invention, the sterilized and neutralized sterilized aquaculture water is supplied to the aquaculture tank by a conventional method and can be applied to an environment very suitable for aquatic organisms. In particular, it can be said that it is very suitable as a method of biological security form in that the harmful environment can be completely protected and protected in the growing process of the organism, and it can be applied to a method for optimizing culture conditions.

Here, the filtration processing unit 120a may be vertically opened in a vertical state or installed vertically opened in an obliquely inclined direction in a direction opposite to a culture water flow moving in the first chamber 100. In this process, the suspended solids, which are filtered by the filtration treatment unit 120a and sink into the second chamber 100, move downward from the first chamber 100 to the next chamber, Since the foreign matter deposited on the bottom of the chamber is collected and discharged to the outside, the foreign matter can be easily removed. That is, in the case of FIG. 6, the structure of the embodiment in which the floating foreign matters are filtered and the foreign substances precipitated are collected and removed in the bottom portion of the first chamber 100 are illustrated.

According to a preferred embodiment of the present invention, the filtration means 121, 121a of the filtration processing unit 120, 120a may have the form of a plate screen screening body, for example, and may have an area The filtration body can be configured in the form of a single mesh-like filter over the entire surface of the culture water flowing in the first chamber 100. In order to smooth the removal of the foreign matter filtered by the filtration body, Lt; / RTI >

According to a preferred embodiment of the present invention, the filtration means 121 and 121a constituted by the conveyor system as described above can be configured to rotate continuously to continuously remove foreign matter from time to time or only when necessary.

According to the present invention, when the filter body is constituted by a conveyor system, for example, as the filter body rotates, foreign matter collected in the filtration means 121 and 121a in the form of a filter body is lifted up to the upper end. 122a provided at the upper end of each of the first and second exhaust ports 121a, 121a.

The foreign substances removing means 122 and 122a further remove the foreign substances drawn up to the upper end portion by the rotation of the filtration body from the surface of the filtration body of the filtration means 121 and 121a, For example, a brush shape.

According to a preferred embodiment of the present invention, the foreign matter discharging means 123 and 123a of the filtration processing unit 120 and 120a are provided with a means for flushing the collected foreign substances while flowing water to the foreign matter removing means 122 and 122a, Or by blowing air with negative pressure by blowing air or blowing air with a positive pressure or discharging it by mechanical means for pushing or scraping foreign materials collected in the trough of the foreign material removing means 122, 122a for removing foreign matter .

As described above, according to the present invention, as shown in FIG. 5 and FIG. 6, in the upper part of the first chamber, the aquaculture water filtering unit 120 and the aquatic- The sterilizing treatment and the neutralization treatment are performed while moving to a plurality of adjacent aquaculture water moving chambers such as the first chamber 100.

According to a preferred embodiment of the present invention, the sterilizing unit 300 and the neutralization unit 400 including the first chamber 100 and the aquamarine moving chamber continuously arranged with the lower and upper flow passages, And a water supply type bio-security system including a water supply unit 500.

1 or 2, the configuration of the aquaculture apparatus according to the present invention is such that before pumping the aquaculture water supplied from the seawater supply unit 20 for supplying seawater or the like, Having a configuration fundamentally different from that of the device for pumping through the pipeline 50 to supply the aquarium to the chamber after passing through the electrolysis device 40, will be.

The first chamber 100 to which the culture water is supplied in the present invention is supplied to the culture water tank through the electrolytic apparatus 40 or the filtration apparatus 30 and the electrolytic apparatus 40 (See FIG. 5 and FIG. 6), a conventional aquaculture system for sterilization and neutralization is applied to a first chamber 100 in which aquaculture water flows directly without filtration or electrolysis, And a sterilization process is performed by generating an oxidant by collectively collecting the aquaculture water in a channel in the first chamber 100. The filtration and the oxidant generating unit are installed in the channel of the aquaculture water treatment system, The shape is unknown.

2 and 3 in that the foreign matter is supplied to the first chamber 100 without filtration through the pipeline 50 despite the presence of foreign matter in the aquaculture water. Is a device configuration fundamentally different from a conventional device configuration that passes through the existing filtration device 30 or the electrolytic device 40 in advance.

According to the present invention, in order to perform sterilization treatment by filtration and oxidant generation, basically, it is composed of a hydrothermal aquaculture water treatment system. In the filtration system of the first chamber, It is possible to efficiently and economically treat the aquaculture water after the wake up in terms of constituting the oxidant generating unit.

According to a preferred embodiment of the present invention, when the fresh water and the seawater are pumped to the upper part of the first chamber, the water mixed type water discharged from several pipelines at the upper part of the first chamber is mixed, And an oxidant generator installed in the ceiling portion of the first chamber, for example, an electrolytic device, is passed between the anode and the cathode plate of the electrolytic apparatus, and the sterilization process is started by the TRO generated in the aquaculture water. Therefore, when the electrolytic apparatus is applied, for example, a screen mesh type filter body of 50-3000 mu m is provided as a filtration means of the filtration treatment unit, so that foreign matter such as floating matters and muddy water and solid matter in the influent waters are directed toward the electrode So that the filtration and sterilization are continuously performed while the culture water continues to move downward.

According to a preferred embodiment of the present invention, the filtration means 121 and 121a may be constituted by filtration means in the form of a conveyor as described above, or simply by filtering foreign matter filtered on the entire surface of the filtration body And a foreign matter removing means having a form that is rotatably or repetitively installed so as to be lifted up.

Therefore, the foreign substances filtered on the surfaces of the filtration means 121 and 121a are lifted up by the foreign matter removing means 122 and 122a at any time, so that the foreign substances filtered on the surfaces of the filtration means 121 and 121a can be very easily removed will be. Therefore, in the filtration processing unit 120, 120a of the present invention, there is no backwashing device or similar facility for removing foreign matter.

Since the filtering units 120 and 120a according to the present invention can be constructed with a very simple structure and the power for removing foreign matter after filtration can be minimized, the filtering units 120 and 120a In particular, in the case of FIGS. 2 and 3, since the foreign matter is removed by the reverse flow treatment method in order to remove the filtered foreign substances, it is very costly to construct the apparatus and the power is excessively consumed, However, in the case of the present invention, the foreign matter can be removed very simply and economically, which makes it possible to replace the conventional impractical equipment with a facility that is economical and can be practically used at a remarkably low cost, which is less than half.

According to a preferred embodiment of the present invention, an electrolytic apparatus or an ozone generating apparatus, which forms another part of the first chamber and receives the filtered water from the filtration processing unit and collectively generates oxidant in the water channel, is buried in the ceiling It is also characterized in that it can include an oxidant generator in the form.

There has been known a technique of sterilizing the aquaculture water using an electrolytic apparatus or the like. However, as in the case of the conventional arts 1 and 2, a sealed electrolytic bath is required for the electrolysis of the aquaculture water to be supplied in an enormous amount Electrolysis of a large amount of aquaculture water into an open state in a water channel collectively has a problem in that it is difficult to electrolyze the electrolysis device 40 at the entrance of each pipeline 50 immediately before being supplied to the pipeline 50, And only the structure in which the water was electrolyzed and pumped to the chamber was possible. However, according to the present invention, the above-mentioned stereotypes are broken and the aquaculture water is directly supplied to the chamber where the sterilization and neutralization are performed without any electrolysis facility, and the supplied aqua water is collectively fed through the filtration processing unit installed in the first chamber And the oxidant is generated collectively by the oxidant generator provided with the electrolytic apparatus or the ozone generator. That is, unlike the existing apparatus, the configuration of the present invention differs from that of the existing apparatus in that the water is supplied to the sterilization and neutralization chamber, a method of installing only an electrode assembly or an ozone dissolution mechanism of an anode and a cathode without a housing and an oxidant generating unit such as an electrolytic apparatus is installed in a landfill manner to generate oxidants collectively for the filtered water will be.

As described above, the present invention is constituted by a series of structures including a filtration processing unit capable of performing filtration collectively within a culture water transfer channel (first chamber) which has not been conventionally applied, and an oxidant generator such as an electrolytic apparatus or an ozone generator The oxidant can be generated very effectively, and the sterilization and insecticidal effect can be efficiently performed.

According to a preferred embodiment of the present invention, sterilization including sterilization cancellation chambers that are sterilized while being continuously supplied while being supplied from the first chamber 100 to the second chamber 200 in a state in which residual oxidant is contained in the aquaculture water And a processing unit 300.

In the present invention, the sterilization treatment unit 300 may be substantially constituted by one or more chambers such as a second chamber 200, a third chamber, etc. Such a chamber configuration is disclosed in Korean Patent No. 10-1498990, The device structure disclosed in Patent No. 10-1547566 can be used as it is.

In addition, according to the present invention, the neutralization processing unit 400 includes a culture water moving chamber for neutralizing the residual oxidant in the chamber while the sterilized culture water is moving. The neutralization processing unit 400 also has a plurality of chambers. The neutralization processing unit 400 may use the facility structure including the chamber disclosed in Korean Patent No. 10-1498990 and Korean Patent No. 10-1547566 of the present inventor.

Therefore, the sterilizing treatment unit 300 and the neutralization treatment unit 400 according to the present invention can be formed of two to eight consecutive chamber structures as shown in FIGS. 7A and 7B according to the most typical example. 7A is an embodiment showing a chamber configuration including a total of six chambers including a first chamber 100 and a second chamber 200 among a plurality of chambers that are aquatic flow moving chambers and includes a sterilizing treatment unit 300 and a neutralization treatment unit 400 shown in FIG. Here, six chambers constituting the sterilizing treatment unit 300 and the neutralization treatment unit 400, and aquaculture water movement path for moving the chambers are indicated by arrows. FIG. 7B is a view It is a diagrammatic representation of the aquaculture route in the chamber.

7a and 7b, the sterilization treatment unit 300 may include one or more aquatic movement chambers, for example, two aquarium movement chambers 100, 200, for example, so that the aquarium can be moved while the aquaculture water is continuously supplied. The oxidant-containing aquaculture water supplied from the oxidant generator 130 is oxidized during the movement of the first chamber 100 and the second chamber 200, which are the aquamarine treatment mobile chambers of the sterilizing treatment unit 300, It is contacted with the harmful microorganisms existing in the aquaculture water and sterilized. The culture water transfer chambers 100 and 200 of the sterilization treatment section may have a plurality of chambers of two or more chambers. Here, in the first chamber 100, the filtration process and the oxidant generation are performed while the culture water moves, and at the same time, the sterilization treatment is performed by the generation of oxidant, which is the first culture water transfer chamber.

In addition, the sterilization treatment water in the sterilization treatment unit 300 is transferred to the neutralization treatment unit 400 in the same manner, and the residual oxidant component is neutralized to remove the oxidant in the water treatment water. The neutralization treatment unit 400 according to the present invention has a neutralizing agent input unit for inputting a neutralizer while the sterilized wastewater is moving and a neutralizing agent for restoring the aquaculture water to the original filtration and sterilized state is introduced, And includes a plurality of aquifer mobile chambers that allow the aquaculture to continue to migrate while the remaining aids in the aquaculture water are removed by neutralization. The neutralization treatment unit 400 may include a plurality of aqua regime chambers in the same or similar manner as the sterilization treatment unit 300, preferably in the same manner.

According to the present invention, it is possible to include a sterilization-type water supply unit 500 for supplying the sterilized aquaculture water, which has been sterilized and neutralized as described above, to a farm of aquatic organisms.

The sterilized aquaculture water supplied to the aquaculture farm using the sterilized aquatic water supply unit 500 is supplied to the aquaculture aquaculture in order to produce the aquatic organisms in an optimal environment.

The aquaculture apparatus according to the present invention can sterilize the aquaculture water in an economical and efficient manner in a watercourse environment. The apparatus is composed of a plurality of filtration apparatuses The present invention is an economical aquaculture apparatus which has an effect of effectively sterilizing the aquaculture water even though it constitutes a simple filtration processing unit and an oxidant generating unit without constituting an electrolytic apparatus.

Hereinafter, the present invention will be described in detail with reference to examples, but the present invention is not limited to the examples.

Experimental Example 1: Change in TRO concentration due to rancidity

When fresh water or seawater is used as aquaculture water, it is not possible to sterilize and insect the aquaculture water by electrolysis or ozone treatment as it is without filtration when a large amount of debris or mud is contained in aquaculture water. Electrolysis tank has 3 ~ 5mm gap between cathode and anode. Therefore, when suspended matter (filtrate, sediment, seaweed, kelp, fish) of 3-5mm or more flows into electrolysis tank, expensive electrode is broken by short circuit Filtration must be performed prior to electrolysis to remove all suspended solids above 3-5 mm prior to electrolysis.

Also, in case of ozone disinfection by ozone generation instead of electrolysis treatment, ozone should be blown out into a small hole of 2 mm or less and dissolve in seawater. Therefore, when ozone is used, the ozone treatment should be performed after removing the floating matter of 2 mm or more.

Therefore, pre-filtration of aquaculture water is necessary to generate TRO by electrolysis, generate TRO by ozone, or to sterilize by oxidant in any case.

Therefore, in order to compare the action and effect of this filtration treatment, four chambers each having a length of 2 m and a height of 2 m were prepared and flowed at a rate of 1.8 m 3 / min for 4 minutes per chamber, (Volt) of 3.51V and Ampere of 245A so that the TRO becomes 1.5 ppm in the second chamber, and then the water is generated at the starting point of the beach entrance. Respectively. The second chamber was equipped with a Hach CL17 TRO automatic meter which measures the TRO every 2 minutes and displays it digitally. When only clear water was introduced, the TRO of 1.5 ppm in the second chamber was significantly lowered to TRO of 0.5-0.6 ppm from the time when the drip was introduced.

For comparison, in the same chamber structure, as shown in FIG. 5, the water is pumped without filtration and electrolysis as it is, and a horizontal partition wall is formed on one side of the first chamber manufactured by the channel method to form a filtering water path. The filtration device and the electrolysis tank were installed with the blocking type filtration structure, and the water was generated in the same manner as the dilution aquaculture device, and the TRO was measured after introducing the culture water. The voltage of the electrolysis tank increased from 3.51V to 3.62V In the second chamber, the TRO state of 1.5 ppm was measured without change.

From the results of this experiment, it was confirmed that the apparatus for making a water channel having the configuration of FIG. 5 does not deteriorate the state of occurrence of TRO unlike the dilution type apparatus of FIG.

Experimental Example 2: Comparison test of sterility

The culture water was treated in the same manner as in Example 1 to sterilize the culture water, and then the culture water was collected from the chamber No. 3 before the neutralization treatment. The viable cell count was tested according to the general living cell count test method. As a result, In the case of the water-aquaculture apparatus, the concentration was measured as 0 cfu / ml, and in the case of the dilution-type apparatus of FIG. 2, 5 -10 cfu / ml of live cells was found. For reference, the number of viable cells was 4,000 cfu / ml in raw water prior to sterilization.

From the results of this experiment, it was confirmed that the hydrothermal aquaculture device of FIG. 5 has a superior sterilization effect as compared with the dilution aquaculture device of FIG. 2, and that the sterilization is not properly performed by using the dilution aquaculture device of FIG.

Experiment 3: Parasite detection comparison experiment

Sterilized in the same manner as in Example 1, and neutralized, and the solids settled in the third chamber and the fourth chamber were collected and the solid substances in the muddy water floating on the top of each chamber were collected and parasite tests such as Scuticociliate and Trichodina As a result, Scuticociliate was detected five times in the dilution type aquarium apparatus as shown in Fig. 2, but no parasite was detected in the water condition aquarium apparatus corresponding to the structure of Fig.

From the results of this experiment, it was confirmed that the water-bath culture apparatus of FIG. 5 had a superior insecticidal effect as compared with the dilution-type culture apparatus of FIG. 2, and that the insecticide was not properly performed using the dilution-type culture apparatus of FIG.

Experimental Example 4: Comparison of characteristics and economical efficiency according to the composition of aquaculture apparatus

2, used in the first embodiment, comprises a dilution type aquarium (a dilution type) having a filtration device in a part of the pipeline and a filtration type aquarium (filtration type) equipped with a filtration device over the entire pipeline shown in Fig. 1 In order to compare the device characteristics and the effects thereof, it is necessary to compare the state of equipments having the same conditions for filtration of aquaculture, The comparative analysis of the economic value according to the required number of equipments according to the comparative example and the equipment configuration according to the number of equipments.

In the following table, the amount of the aquaculture water equivalent to the amount of filtrate is based on the basic water volume required for the operation of a typical water surface area of 5,000 m ² .

The results are shown in Table 1 below.

Compare Diluted Filtration Waterway ① Filtration quantity 1 -10% Whole inflow Whole inflow ② Quantity of passing between electrodes 1-10% of the total inflow Whole inflow Whole inflow ③ Sterility of feces - In the same TRO, the sterilizing power is weakened to less than 50%, so TRO should be increased more than 2 times.
- There are big drawbacks that TRO elimination electricity cost and TRO removal after sterilization are twice as expensive. 100% 100% ④ Reverse flow cleaning high filter installation number (based on 5000 square meter farm) - Underground seawater need no filter
- Requires one filter washer in the area without underground seawater One withdrawal pipeline requires one strainer.
(Total 7-9 required) One open, low-cost screen is sufficient
(No expensive backwash filter required) ⑤ Filter type Closed-back flushing filter is necessary because it must be installed in the pipeline. Same as left In an open water tank
It is enough to install a simple filter net at the entrance to the channel. ⑥ Installation cost of filter One in need of underground seawater
(About 100 million won) Total 7-9 required
(About 700 million won) One filter net
(About 50 million won) ⑦ Installed number of electrolysis tank (based on 5000m3 of farm) 3 units (1 spare unit) 7-9 Two (one for spare) ⑧ Installation cost of electrolysis tank 50 million won
= About 150 million won 50 million won
= About 400 million won 50 million won
= About 100 million won (⑥ + ⑧) Install filter and electrolytic bath Total cost Approximately 250 million won About 1.1 billion won About 150 million won

From the above comparison results, it can be concluded that the TRO concentration should be increased to increase the TRO concentration as in ③ of the dilution formula, There is a fatal disadvantage such as a relatively high cost in installation and in the case of filtration type, it is found that there is a disadvantage in that it is practically impossible to put into practical use because a large amount of expensive cost is required for installing a backwashing washing machine, a filter and an electrolytic bath.

On the other hand, in the case of the water channel system according to the present invention, the installation cost of the filter and the electrolytic cell is about 1/2 as compared with the dilution type and less than 1/7 of the filtration type, and the cost of the bio- Sterilization and insecticidal effect were found to be rather superior. In the construction of the biological security aquarium according to the present invention, filtration and sterilization treatment are collectively carried out through the facilities installed in the water channel of the aquamarine transport chamber which is a sterilization and neutralization chamber without filtration and electrolytic treatment unlike the existing pretreatment It was found to be an amazing effect achieved through the construction of a new concept of a waterway.
