Abstract

There may be various kinds of facilities to sterilize the breeding water of fish farms using the seawater. However, after sterilizing the farming water using ozone, the fish are separated so that the fish are not damaged by this sterilizing water. It is a sterilizer that adds a treatment device These additional treatment units are not necessary for fresh water, but must be used for seawater, otherwise farmed fish will be killed or damaged.

The principle of the seawater sterilizer using ozone is that when ozone is injected into the seawater, bromine or iodine contained in the seawater reacts first with ozone to form an oxidizing agent such as bromic acid or hypobromic acid. The remaining oxidant (residual oxidant, Total Residual Oxidant) is used to have the ability to sterilize. After ozone is injected into clean (low organic matter) seawater that is used as aquaculture water in aquaculture farms, the residual oxidant (TRO) needs time to naturally decrease to a safe concentration. Before supplying sterilized seawater to aquaculture tanks, it is necessary to store them for a long time or limit the amount of ozone injected into the seawater to a very small amount. However, in order to store a large amount of water for a long time, a large-capacity tank is needed. Since the method currently used in aquaculture farms uses a method of directly injecting a very small amount of ozone into a breeding tank, the amount of ozone is sterilized. If the fish exceeds the required level, the farmed fish are also damaged, and the purpose of sterilization cannot be sufficiently achieved without causing damage to the farmed fish.

In order to solve this problem, an appropriate amount of ozone is injected into the seawater, and the concentration of sufficient residual oxidant is artificially reduced to the safe level of the fish, and then supplied to the aquarium, so that the fish is safe and sterilized. It is a device designed to use the raised breeding water.

Description

Sea water sterilization equipment of marine products farm

The present invention is a seawater sterilizer of aquaculture farms, so that the farmed water with sterilizing ability using ozone can be used as aquaculture water without being harmed by farmed fish.

In the past, the use of seawater sterilization for fish farming, which has been partially employed in aquaculture farms, has introduced seawater into the seawater tank where fish are farmed, and raised fish is generally used for broth and some iodine. It contains oxidant by reacting with ozone which is added to seawater, and used to sterilize seawater by oxidizing and killing cell membranes of pathogenic cells due to the oxidant produced. The concentration of oxidant required for sterilization is 1.0mg. / l, whereas the concentration of safe oxidant for aquaculture fish is less than 0.003mg / ℓ, the amount of ozone to be added and the amount of residual oxidant remaining in the sea water after oxidation is necessary for normal sterilization that can safely inhabit fish. Reduction of residual oxidant in seawater naturally by TRO (Total Residual Oxidant) There is a problem that it takes a long time to grow, it is not possible to use the sterilized seawater to be put into the seawater tank immediately, there is a problem that can not supply the seawater required for aquaculture smoothly, to solve this problem To reduce the amount of ozone that is added to seawater for immediate use, the required sterilization concentration is not formed, and it does not protect enough fish from pathogenic bacteria, viruses, and parasites that cause diseases of farmed fish. Because of poor sterilization, red tide occurs, and red tide does not block or eradicate even if it enters seawater, causing a problem that farmed fish are damaged by toxins caused by red tide.

The present invention has been made in view of these problems, and it is possible to add ozone to the breeding water in the reaction tank containing the water to inhabit the farmed fish, and to reduce the oxidation ability of the sterilized breeding water and the sterilized breeding water to keep the breeding water. By additionally installing the device, sterilizing the breeding water of farmed fish and immediately injecting it into the breeding tank through a reducing device, it is designed to enable farming with sterilized water without damage to the farmed fish. It will be described in detail as follows.

Sterilization fluid provided with an ozone concentration meter 6 and a disinfectant water supply pump 7 connected to the central control panel 5 in the reactor 4 in which the ozone generator 1, the mixer 2, and the mixing pump 3 are installed. By connecting the tank (8), the breeding tank (9) is connected to the catalyst reduction tank (10) connected to the sterilization retention tank (8) by the sterilizing water supply pump (11).

The present invention as described above allows the central control panel 5 to control mixing of the amount of ozone generated by the ozone generator 1 installed in the reactor 4 with the amount of ozone generated by the mixer 2, and the reaction tank 4. Control the sterilizing water supply pump 11, the fast-acting water supply pump (7) and the mixing pump (3) for supplying the ozone concentration meter (6) and the sea water (13) formed in the) to the catalytic reduction tank (10) Seawater 13 is introduced into the reaction tank 4 of the seawater sterilization device 12, and the ozone generated in the ozone generator 1 operating as the central control panel 5 is mixed through the mixer 2 for mixing. When mixed with the seawater 13 introduced into the reaction tank 4 by the pump 3, the bromine and urethra of about 60 mg / L contained in the seawater 13 introduced into the reaction tank 4 are reacted first in a very short time. To form an oxidizing agent (Oxidant, Bro, Bro3), and thus formed oxidizing agent has a strong sterilization action, and is introduced into the reactor (4) Since ozone introduced into the seawater 13 is injected in gaseous form, organic matter in the seawater 13 floats in the form of bubbles, and various kinds of particles suspended in the water float together in the state of being attached to the surface of the bubbles. When the bubbles generated on the surface of the seawater 13 are removed using a separate device, the organic matter contained in the water can be removed. The ozone injected into the seawater 13 is a gaseous ozone to the atmospheric layer. Almost all can increase sterilization concentration in the water, and pathogenic bacteria, viruses, and parasites contained in the seawater 13 can be reacted with the residual tank TRO (Total Residual Oxidant) by the reaction tank 4 and the sterilization tank. Seawater 13 that is killed or inactivated in (8) and sterilized flows into the sterilization tank 8 in which the ozone concentration meter 6 is installed and passes through the central control panel 5 to the sterilization tank ( 8) glass of seawater (13) flowing into It is possible to measure the amount of oxidizing agent, discharged through the disinfection water supply pump (7) without going through a reducing device in the sterilization tank (8), can be used as disinfection water for sterilization of aquaculture tools, farmed fish In order to supply the breeding water to the breeding tank 9, where the breeding tank is inhabited, the breeding tank is maintained for a predetermined time in accordance with the need of time to be oxidized by the amount of ozone in the sterilizing tank 8. The microorganisms included in 8) have different ozone concentrations, treatment time and bactericidal effects depending on the amount of ozone introduced.For example, in the case of infectious hematopoietic organ necrosis virus, 100% within 30 seconds at an ozone concentration of 0.01 mg / l In the case of infectious pancreatic necrosis virus, 99.9% of bactericidal effect occurs after 30 to 60 seconds at ozone concentration of 0.5-1.1mg / l. Since the sterilization effect according to the concentration or treatment time of the microorganism sterilization is applied differently, gives the time required for sterilization for each microorganism contained in the seawater 13, the oxidation activity of the oxidant is not finished and the amount of residual oxidant is large The remaining sea water (13) is introduced into the catalytic reduction tank (10) as a reducing device by feeding the breeding water to the sterilization water supply pump (11) installed in the sterilization tank (8). ) By catalysis by catalytic reaction to remove the sterilization ability (oxidation capacity) contained in seawater (13) and keep the concentration of oxidant at 0.003mg / l or less safe for fish. ) To be able to breed farmed fish.

As described in detail above, the present invention is a breeding tank using the catalytic reduction tank (10) in the sterilization tank (8) for the seawater (13) which has been oxidized with ozone in the breeding tank (4). Even if it is injected immediately into (9), it is possible to supply the farmed water smoothly by allowing the farmed fish to be sterilized without harming the farmed fish, which causes the disease of the farmed fish contained in the natural fresh water. It protects farmed fish from pathogenic bacteria, viruses, and parasites, and can prevent the influx of red tide organisms to breeding tanks (9) even when red tide occurs, thus detoxifying poison by red tide organisms to prevent damage to farmed fish. It will have the effect of breeding smooth farmed fish.
