Description

Seaweed farming net activator treatment device and treatment method using the same {Processing apparatus for treating agent of activation for laver farming net and Processing method using the same}

The present invention relates to a seaweed farming network activating agent processing device and a processing method using the same.

The production of seaweed in Korea in 2021 was 547,000 tons, accounting for about 29.7% of the total seaweed production, but the amount was 474,955 million won, accounting for 62.5%. The production of seaweed in Korea increased from 20,000 tons in the 1960s to 270,000 tons in the late 1990s. In addition, mass production has become possible due to advances in aquaculture technology, such as the development of glass filamentous artificial seedling technology, the introduction of high-yield varieties of radiation-patterned seaweed, and the dissemination of on-land seedling and freezing net technology.

On the other hand, the side-by-side aquaculture method is a technology suitable for mass aquaculture, and the time in which seaweed is in the water is longer than the prop method, which has the advantage of nutrient absorption. . However, due to the long immersion time in seawater, adhesion of epiphytes, miscellaneous algae and diatoms increases, and the incidence of dog disease is high. In order to solve these disadvantages, an active treatment agent has been developed, and the use of an active treatment agent also contributes to an increase in seaweed production.

In seaweed farms in Korea, the active treatment agent has been used since the 1980s to control seaweed and miscellaneous algae attached to seaweed and to prevent seaweed disease. The activator notification was enacted in 1994 for the spread of seaweed farming methods and the safety of fishermen due to the illegal use of inorganic acids. Due to the continuous demand for an increase in inorganic acid content for reasons such as inconvenience, the inorganic acid content of the active treatment agent increased to 3% in 1997, to 5% in 2000, and to 9.5% in 2004. zero, the content of inorganic acid was revised to 8.0~9.5%, and the content of organic acid to 15% or more. In addition, an electrolytic water activation treatment agent was added to the notice in 2010, an activation treatment agent containing nutrients was added in 2014, and an organic acid content was changed to 10% or less in 2017, and a high salt water activation treatment agent was additionally established.

As a result of previous studies related to the aquaculture efficacy of the active treatment agent, it was found that the organic acid active treatment agent containing 9.5% inorganic acid was effective in controlling green algae and diatoms and inhibiting caviar disease within the appropriate dilution ratio and appropriate treatment time range. It was investigated that the organic acid active treatment agent containing inorganic acid did not have a significant impact on the marine environment, and there was no problem with the food safety of activated seaweed.

On the other hand, as a conventional technique for processing an active treatment agent in seaweed farming nets, Korean Patent Registration No. 10-1345130 is loaded on a ship and passes through the inside of the treatment tank according to the movement of the acid treatment agent and the treatment tank in which the ship is stored. A seaweed active treatment agent treatment device having a floating preventing means for preventing the seaweed farming net from floating so that the seaweed farming net is submerged in the acid treatment agent has been disclosed.

However, in the case of treating seaweed farming nets with organic acid activator in the conventional method, there is a disadvantage that more expensive organic acid must be used, so fishermen prefer to use inorganic acid, which is cheaper than organic acid activator and can be activated in a small amount. are doing

Therefore, in order to prevent the increase in consumers' distrust of seaweed food due to the use of inorganic acids and the adverse effect on seaweed exports, there is an urgent need for a plan to improve the effect of the active treatment agent prescribed in the notification. In addition, at the present time when interest in the farm environment and food safety are being emphasized internationally, comprehensive research is needed to improve the efficacy of active treatment agents in order to solve the problems caused by the use of inorganic acids.

Therefore, in this study, as part of a method to increase the effectiveness of the seaweed farming net activator, a seaweed activator treatment device using an air bubble spraying device was developed, and by using this, the effect of removing diatoms and leaf algae attached to the seaweed farming net was significantly improved. It was confirmed that it was, and the present invention was completed.

From the above results, when using a high-salinity active treatment agent, it is possible to increase the effect of removing diatoms from seaweed farming nets, and when using a high-salinity active treatment agent but using an air bubble injection pipe, compared to the case of not using an air bubble injection pipe It can be seen that it can be improved by about 2.2 times.

From the above results, it can be confirmed that the removal effect of suspended matter (diatoms, etc.) in the seaweed farming net can be significantly increased when the active treatment agent is treated by spraying air bubbles compared to the case where the organic acid activator and the high salt water activator are treated alone. can

In addition, the dry weight of suspended matter (diatoms, etc.) in the treatment condition ④ (organic acid active treatment agent + air bubble treatment) was 370.4 mg/L, whereas the suspended matter (diatoms, etc.) in the treatment condition ⑥ (high salt water active treatment agent + air bubble treatment) etc.) of dry weight of 241.9mg/L, as an activator, in the case of using organic acid activator compared to the case of using high salt water activator and air chamber, suspended matter (diatoms, etc.) ) It can be seen that the removal effect is about 65.3% better.

<Experimental Example 2> Seaweed farming net washing experiment of activator treatment device (2)

As the cleaning effect of the seaweed farming network of the active treatment agent treatment device according to an embodiment, in order to confirm the effect of removing leaf green leaf bodies included as impurities in the seaweed farming network by air bubbles, an air bubble washing indoor experiment was performed as follows did

Specifically, as shown in FIG. 10, a 15-hole air basin connected to an air pump was attached to the bottom of a glass tank (45 cm wide, 20 cm long, 25.5 cm high) to manufacture an air bubble indoor experiment device, and the stock solution of the active treatment agent in the tank. After filling 6L of a solution diluted with seawater, the seaweed and leaf halves were treated, but in order to confirm the cleaning effect according to the concentration of the active treatment agent in the solution, the solution was 20, 30, 40 times the stock solution of the active treatment agent In order to prepare differently diluted solutions with different amounts of seawater, and to confirm the effect of air bubble treatment time, air bubbles are not sprayed for each of the different concentration solutions, or sprayed for 5, 10, and 20 seconds Radiant seaweed and leaf green leaf halves were treated differently in this way.

Thereafter, after collecting each of the treated radiation seaweed and leaf green leaf halves, they were dyed with a 0.1% erythrosine staining solution for 1 minute, washed with sterilized seawater three times, and pictures were taken with a digital camera, and shown in FIG. and the dead cell rate was measured, and the results are shown in FIGS. 12 and 13.

12 is the dead cell rate of radiation laver, and FIG. 13 is the dead cell rate of leaf algae thallus, as shown in FIG. It can be confirmed that the green leaf body is higher than 60%. Through the above results, it can be confirmed that leaf algae attached to seaweed can be removed by the activating agent and air bubble treatment.

In addition, in the case of leaf greens, when air bubbles were not sprayed when 20-fold diluted organic acid activator was treated for 5, 10, and 20 seconds, the rate of dead cells was 88.8%, 97.7%, and 98.4%, whereas when air bubbles were sprayed As the dead cell rates were 97.7%, 97.9%, and 99.1%, it could be confirmed that when air bubbles were sprayed, the dead cell rates increased by 8.9%, 10.2%, and 0.7%, respectively.

In addition, when the 30-fold diluted organic acid activator was treated for 5, 10, and 20 seconds, the dead cell rates when air bubbles were not sprayed were 60.8%, 83.7%, and 96.3%, whereas the dead cell rates when air bubbles were sprayed were respectively As 88.7%, 89.2%, and 97.1%, it can be seen that when air bubbles are sprayed, the dead cell rates increase by 27.9%, 5.5%, and 0.8%, respectively.

In addition, when the 40-fold diluted organic acid activator was treated for 5, 10, and 20 seconds, the dead cell rates were 21.8%, 85.1%, and 91.8% when air bubbles were not sprayed, whereas the dead cell rates when air bubbles were sprayed were As 93.9%, 91.2%, and 98.3%, respectively, when air bubbles are sprayed, it can be seen that the dead cell rate increases by 72.1%, 6.1%, and 6.5%, respectively.

From the above results, it can be confirmed that when treating the seaweed farming net with an organic acid activator, the effect of removing leaf flecks can be significantly improved by spraying air bubbles together.
