Description

Circulation and filtration farming apparatus equip with the pH control system

The present invention relates to a circulating filtration aquaculture apparatus, and more specifically, to automatically monitor the pH in the circulating filtration aquaculture to adjust the pH suitable for the growth of various aquatic organisms, including abalone, to enable a stable aquaculture. In addition, the present invention relates to a circulating filtered aquaculture device having a pH control system for improving the quality of aquaculture organisms.

More than 100 abalones are known throughout the world, and they are used in various fields, including edible and decorative. As a result, the demand for abalone has increased greatly, which has led to an increase in the number of places that farm abalone in recent years.

The abalone farming usually consists of farming by discharge and drowning by chalong. However, farming by discharge has very low abalone survival rate, and divers or haenyeo must harvest when harvesting. In addition, there is a disadvantage that the drowning mode by chalong takes feed and labor costs for feeding abalone, is not easy to manage and eliminate adherent organisms, and the risk of theft and loss due to typhoons.

In order to make up for these shortcomings, land tank farming technology has been disclosed. The land tank farming technology is to grow a high density in the tank after growing a young chip of the organism to be farmed, including abalone. Most of these terrestrial aquaculture farms use a circulation system in which sewage used in aquaculture tanks is sent to a biological filtration tank, or seawater is introduced into the tank for purification through biological treatment.

When the abalone is farmed by applying the circulation method, it is possible to increase the survival rate as well as increase the growth rate as compared to the discharge of the existing young tooth packs. However, it takes a long time to purify the sewage in the biological filtration tank does not smoothly circulate the water in the culture tank, and thus has a disadvantage that the period of the abalone is long. In addition, there is a disadvantage in that the disposal of waste products such as abalone droppings are not properly made, the overall breeding environment is lowered to increase the abalone mortality.

In order to solve the above problems, the present inventors have described a technique related to a circulating filtered aquaculture device for pretreatment to remove wastewater from abalone before purifying sewage discharged from aquaculture tanks in a domestic filtration system in Korean Utility Model No. 288533. It has been disclosed.

Looking at the technology disclosed in the domestic registered utility model No. 288533 with reference to Figure 1 attached to the circulating filtration aquaculture device is a culture tank (10); A bubble removing device (20) for removing bubbles of filthy water discharged from the culture tank (10); A thermostat 30 for maintaining a constant temperature of the wastewater discharged from the bubble removing device 20; It includes a biological filtration tank 40 for biological treatment of the sewage introduced from the thermostat 30 to the culture tank (10).

Sewage discharged from the culture tank (10) in the circulating filtration culture device is purified by passing through the bubble removing device 20, the thermostat (30) and the biological filtration tank 40 is introduced back into the culture tank (10). In this way, the wastewater discharged from the aquaculture tank 10 is passed through the bubble removing device 20 immediately before the biofiltration tank 40 is treated, thereby shortening the purification time in the biofiltration tank 40 to increase the aquaculture efficiency of the abalone. In addition, it is possible to improve the rearing environment, increase the growth efficiency of abalone, and reduce mortality. In particular, the circulating filtration-type farming apparatus of the above configuration is not affected by the external environment to provide a stable breeding environment, it is possible to breed aquaculture organisms year-round can greatly shorten the breeding period.

However, as described above, conventional circulating filtered aquaculture systems can provide water quality conditions suitable for the growth of aquaculture organisms through several stages of water treatment facilities, Nitrification tends to reduce the pH in the aquaculture system.

As such, the decrease in pH inhibits the metabolism and growth of aquaculture organisms, and the hemoglobin in the blood binds to oxygen, and enough dissolved oxygen is supplied despite breeding organisms asphyxiating. In addition, the nitrifying bacteria in the biological filtration tank, like the breeding organisms, do not perform normal nitrification at a low pH, which causes a balance of the water environment, resulting in a decrease in productivity of the aquaculture organisms and a large mortality. In particular, in the case of abalone, there is a problem that causes shell malformation, hardening and thinning due to the decrease in pH.

Therefore, the present invention has been devised to solve the above-mentioned problems, and the circulation filtration form that can reliably farm organisms such as abalone by automatically monitoring and adjusting the pH of the water in the circulating filtration system. The purpose is to provide a device.

In particular, in the case of abalone, it is possible to suppress shell malformations, hardening and thinning due to a decrease in pH.

The culture tank 10 and the bubble removing device 20, the thermostat 30 and the biological filtration tank 40 can be easily formed through a known technique, for which the applicant has been registered and registered in advance It is also described in detail in Korean Registered Utility Model No. 288533.

The pH control system according to the present invention measures the pH of the influent water flowing into the culture tank (10), and injects the pH control solution to the effluent discharged from the bubble removing device 20 based on the measured value biofiltration tank (40) It is configured to be transferred to. The pH control system for this purpose is to store the pH adjustment liquid, the stirrer 51 and the motor 52 is equipped with a chemical tank 50, and a fixed amount pump for injecting a predetermined amount of pH control liquid of the chemical tank 50 into the sewage (60), and the control box 70 for controlling the driving of the chemical liquid tank 50 and the metering pump 60 based on the measured pH value of the inflow water flowing into the culture tank (10).
