Description

BACKGROUND OF THE INVENTION {Growing method of fish and vegetables using circulating farming of natural ecosystem}

The present invention is a technology related to the application method of a circulation system for simultaneously obtaining fish breeding and vegetable crops by applying the circular farming technology of the natural ecosystem, and more specifically, according to the type and size of fish so that fish can be self-sufficient in food. A fish farm that can supply vegetable and animal food is provided, and each water level control device is applied to maintain the water level of the fish farm, but contamination of excrement containing ammonia nitrogen generated during the process of growing fish inside the fish farm It is applied to transfer water to the activated sludge tank, and the contaminated water stored in the activated sludge tank is converted into harmless nitrate nitrogen from harmful ammonia nitrogen by the activated sludge method including photocatalyst, microbial carrier and bubbling, and vegetable crops After changing to propagate a large amount of beneficial microorganisms, the activated sludge treatment water is configured to be transferred to the vegetable cultivation area, and the crops in the vegetable cultivation area absorb the nutrient water provided by the activated sludge treatment water, resulting in excellent freshness and high quality of the crop. Regarding the simultaneous growth method of fish and vegetable crops provided including a circulation system applied to absorb and grow nutrients to provide increased yield and eutrophication elements and harmful substances contained in fish excrement and then introduced into fish farms It's technology.

The modern aquaculture industry is one of the industrial sectors attracting attention amid concerns and concerns about sustainability.

Various problems related to environmental pollution such as pollution problems caused by the production and use of fish meal used as a main feed ingredient, and reckless discharge of waste into the natural environment from marine cage farms have been raised. Concerns about Sustainability aquaculture systems are increasing the demand for systems, and Aquaponics is drawing attention as a new production method to meet these demands.

Aqua phonics is a production system that combines aquaculture and hydroponic among agricultural methods. Water purification and plants absorb various inorganic substances generated in the breeding water produced during the aquaculture process as growth nutrients. It can be said that it is an organic production method based on the water cycle of an ecosystem where growth continues and the breeding water is continuously reused while aquaculture and crop cultivation can be carried out at the same time.

Fish that ingested the feed supplied in the fish farming process discharge various inorganic substances into the breeding water through various metabolic activities, and the continuous accumulation of dissolved organic matter in the breeding water causes environmental pollution of the breeding water. Depending on the concentration, it can be fatal to farmed fish.

Aquaphonics purifies toxic substances in the breeding water by supplying the breeding water used in the aquaculture process to the plants and absorbing various inorganic substances present in the breeding water from the roots of the plants as nutrients.

The most important factor in Aqua Phonics is the Raising Water Recirculation Aquaculture System (RAS), which is continuously reused after removing and purifying pollutants in the breeding water.

The industrial expansion of RAS, which can reduce the environmental burden caused by aquaculture farms, is progressing slowly due to the high initial capital demand, and high stocking density and production are required to cover the investment cost, and as a result, the growth of farmed fish is reduced and Disease outbreaks and welfare problems may occur.

Further, according to Russo et al. (1974) RAS is because the water exchange for less than 10% of the water quantity total facilities in a day due to the lack of oxygen and an organic substance, ammonia, and the like of inorganic nitrogen and accumulation such as a CO ₂ continue to water pollution It is argued that if the water quality is not managed well, fish cannot be raised healthy due to growth inhibition and disease.However, for the continuous reuse of breeding water, the metabolism of fish farmed during the aquaculture process and feed remaining without consumption. Since nitrate nitrogen produced by nitrate is toxic to fish, a biological filtration process that induces oxidation with relatively harmless nitrate is essential.If the concentration of nitrate increases, the pH decreases and it affects the growth of fish. Studies to lower the concentration by using oxidation and aquatic plants are continuing.

However, most of the domestic onshore aquaculture farms take in nearby groundwater and river water, use it as breeding water, and discharge only after passing through a simple settling facility.In some farms with RAS structure, the quality of breeding water is improved through mechanical and chemical action. As the quality of nearby rivers and groundwater deteriorates, and this freshwater is again used as raw water for breeding, there is a vicious cycle of eutrophication, green algae, red tide, and other damages occurring in these waters. to be.

The Aquaphonics System is a method that can complement each other's problems of environmental pollution load of inland water farms and nutrient solution supply and treatment of hydroponic cultivation, and researches are continuously conducted both domestically and internationally, and in the industrialization stage in the United States, Europe, and Australia. However, limitations are exposed in the aspect of simultaneously grafting fish farming and water quality improvement along with environmental and economic issues.

Accordingly, it is essential to exchange with other fields such as BT, ICT, and NT due to the technical characteristics of Aquaphonics, and research and development and strategies taking this into consideration are necessary.

Looking at Comparative Examples 1 to 4, which are conventional methods, as shown in Table 1, the water quality of fish farms is mostly composed of ammonia nitrogen rather than nitrate nitrogen, which is included in the excrement due to the bowel activity of the fish. Most of the ammonia nitrogen is used, and the concentration of ammonia nitrogen in the water flowing into the vegetable cultivation area is also very high. In the case of chemical oxygen demand, the concentration is about 6 ppm, and it is used as a fish farm storage tank or vegetable cultivation area. As the result of chemical oxygen demand of the introduced water is similar, according to the conventional method, water pollution persists due to lack of oxygen due to lack of removal ability of organic matter dissolved in water, organic matter, and inorganic nitrogen such as ammonia, and water quality management is not possible. In this case, it is not possible to grow fish in a healthy way due to growth inhibition or disease occurrence, and at the same time, it is expected that there will be many limitations in cultivation of vegetable crops.

On the other hand, when the breeding water of fish by the activated sludge method is treated according to the embodiment of the present application, it can be maintained with a low concentration of harmless ammonia nitrogen, thus preventing water pollution due to eutrophication, as well as the value of chemical oxygen demand. It can be confirmed that the purification effect of contaminated water quality is great because it can drop significantly.

In addition, when the activated sludge method was secondarily treated after passing through vegetable cultivation, the demand for ammonia nitrogen and nitrate nitrogen and chemical oxygen, which are environmental pollutants, decreased significantly, and the increase rate of crops was found to be 30% or more higher than that of the conventional method. By treating the contaminated water introduced into the activated sludge by the activated sludge method, including eutrophication elements contained in the excrement of fish reared inside the fish farm, a large amount of aerobic microorganisms are multiplied, and the water supplying a large amount of these aerobic microorganisms Therefore, it is believed that it contributed to the increase and increase of tolerance during the crop growth process.

In addition, as a source of carbon dioxide is provided to promote photosynthesis inside a closed green house during the winter crop cultivation process, the growth rate of crops is very large. It is expected to contribute greatly to the sustainable development and potential of the eco-friendly agricultural and fishery industry in Korea.
