Hydroponic cultivation system using biofloc breeding water {Apparatus for biofloc aquaculture and aquaphonic system}

The present invention relates to a hydroponic cultivation system using bio-flock breeding water. More specifically, the bio-flock breeding water drained from the bio-flock culture tank is supplied as cultivation water of hydroponic cultivation, and the purified water cultivated by plant cultivation. It relates to a hydroponic cultivation system using bio-flock breeding water that can be re-supplied as bio-flock breeding water.

The production structure of fishing has been shifted from catching to cultivating. As a result, as one of the cultivated fish farming industry grows indiscriminately, pollution of the marine ecosystem has been intensified with excrement such as food waste and fish discharged from the farm, and research and development of sustainable eco-friendly aquaculture technology to prevent this is being activated. .

Eco-friendly aquaculture refers to green technology that can increase production compared to general aquaculture methods by continuously using the sea while minimizing marine environmental pollution. Eco-friendly aquaculture technology includes development of aquaculture varieties that can be fully cultured without antibiotics due to its strong resistance to disease, methods of purifying and farming water quality without circulating breeding water using beneficial microorganisms, and farming various aquaculture species using a food chain. . In recent years, biofloc technology, which has excellent ability to degrade pollutants and grows fish-friendly microorganisms in aquaculture tanks with fish, has been well received.

BioFloc Technology (BFT) is used to grow aquatic species and useful microorganisms of heterotrophic bacteria and autotrophic bacteria, while bacteria can grow ammonia, etc. It can decompose organic by-products harmful to farmed fish, convert them into food that can be consumed by farmed fish, and also purify the breeding water. Microorganisms not only produce nutrients, but also remove ammonia nitrogen and purify water, so there is no need to change or filter water during aquaculture.

By using bio-flock technology, it is possible to decompose organic substances at a rate of about 10 to 100 times faster than decomposition by algea, so it can be maintained as a breeding water suitable for aquaculture. In addition, this technology can create a closed breeding system that can fundamentally block the influx of viruses, pathogens, and parasites, etc., by water exchange during the aquaculture process, and can control viral infection, thereby preventing the use of antibiotics. It can be drastically reduced. In addition, aquaculture fish can be produced regardless of the season by controlling the environmental conditions at the on-site breeding facility.

Bio-Flock technology, which can continuously produce eco-friendly and clean food, has recently expanded its target species to whitefish, eel, yellowtail, loach, silk carp, etc., and can supply eco-friendly aquaculture fish for all seasons. It also contributes to the increase in farm household income.

The bio-flock breeding water drained from the bio-flock farming section moves to the water storage tank via the water tank drain line (100). The bio-flock breeding water that has been moved to the water storage tank is discharged to the outside through the water tank drainage pipe 300 installed at the bottom of the water storage tank, and excretion and feed debris of a relatively heavy aquaculture fish species are physically purified, and the remaining water is excluded. Moves to the plant cultivation unit through the cultivation unit supply line 200.

The breeding water moved from the cultivation unit supply line is supplied to edible or ornamental plants as cultivation water, and the cultivated water purified by plant cultivation is drained through the cultivation drain line 600 and stored in a recovery tank. The cultivation water stored in the recovery tank may be supplied to the biofloc farming section again as breeding water or drained to the outside through the re-supply line 600.

The bio-flock farming unit S may be installed with a bio-flock farming system to which conventional bio-flock technology is applied. BioFloc Technology (BioFloc Technology) of the present invention is ammonia in breeding water while farming useful microorganisms and cultured fish species of heterotrophic bacteria and autotrophic bacteria. It decomposes organic by-products harmful to aquaculture fish, such as converting them into food that can be consumed by aquaculture fish, and purifying the breeding water, thereby referring to aquaculture methods that do not require return or filtration in the aquaculture process.

As an embodiment, one or more water tanks of a polygonal bio-flock form formed of a certain diameter and depth are installed, and an automatic feed supply system, an underwater pump, and an oxygen supply device are installed at one side of the tank to measure the amount of feed in real time, the amount of dissolved oxygen in the breeding water, etc. It detects and controls the environment suitable for the planted aquatic organisms, and at the same time, prevents organic matter such as food and debris from sedimenting.

Aquaculture fish species that are introduced into the biofloc farming tank are commonly cultured fish species capable of biofloc farming, and may include whiteleg shrimp, eel, yellowtail, loach, and koi. On one side of the aquaculture tank, a water tank drainage line and a re-supply line capable of re-supplying the breeding water purified by plant cultivation in the plant cultivation section are installed so that the biofloc breeding water can be drained.

Figure 2 shows a partial cut-away view of the reservoir of the hydroponic cultivation system using the bio-flock breeding water of the present invention. The water storage tank (A) of the present invention forms a polygonal columnar structure with a side wall of a certain height surrounding the upper and bottom portions of the polygon, and a space in which the bio-flock breeding water drained from the bio-flock culture section is stored is formed. .

A water tank drainage line is horizontally connected to one side wall of the reservoir, and a cultivation part supply line is connected to the other side wall in parallel, so that the biofloc breeding water drained from the biofloc farming section can move to the plant cultivation section. In addition, a reservoir tank drainage pipe 300 is installed at the bottom of the reservoir, so that relatively large specific gravity of food waste and wastes of farmed fish species may sink and be discharged to the outside.

Inside the reservoir, a plurality of impact plates 800 of a slate plate structure are installed at regular intervals and vertically. The side part of the shock plate is installed while forming a certain distance in parallel with the water tank drainage line and the cultivation part supply line. One or more shock plates are installed, but the upper side of a single shock plate is installed so as to come into contact with the upper part of the water tank, and the other shock plates installed on the back are spaced apart from the upper part of the water tank, and the shock plates that are not in contact with the upper part of the water tank are in contact with the lower part of the water tank. You can also Accordingly, the height and height of the impact plate are repeated, and accordingly, the upper part of the water storage tank forms a passage through which the breeding water moves in a zigzag form.

The biofloc breeding water drained from the water tank drainage line has a constant drain pressure, and the water drainage water strikes the shock plate inside the water tank and the waves are dispersed. At this time, the organic matter, such as feed residue of large-sized and large-sized particles contained in bio-flock breeding water, and waste products of farmed fish species, can be separated from the breeding water and settled to the bottom to be discharged into the reservoir drainage pipe.

The bio-flock breeding water that is not discharged to the water tank drainage pipe may continuously separate the sludge while flowing along the zigzag-type breeding water movement passage formed by the shock plate.

The valve frame is installed in a pair on the side of a single shock plate and on the other side of the other shock plate, and is formed of a plate structure that forms an inclination so that the width of the movement path can be narrowed according to the direction of the number of livestock flowing along the movement passage.

Drainage pressure may be dissipated as the bio-flock breeders collide with the impact plate, and as the water pressure weakens, the breeders drained to the bio-flock farming section may reverse flow in the opposite direction. The valve frame helps the breeder to move smoothly in the progress direction, and prevents back flow from occurring as the water pressure becomes weaker.

The shock plate does not require replacement of the filter medium as compared to the method in which the existing filter medium was installed to purify, and the physical purification is performed at the same time as the breeding water is moved using the drainage pressure, so that separate energy supply can be omitted. Through physical purification, there is an effect of separating aquaculture wastes and feed debris, except for expensive bio-flock useful microorganisms, from breeding water.

A cover is installed on the top of the storage water storage frame, and one or more atomization supply holes 701a are formed on the side of the cover, so that the bio-flock breeding water that has been evaporated by the ultrasonic vibration and becomes atomized can be supplied to the nutrient solution container as the water. .

When supplying the existing bio-flock breeding water to the hydroponic cultivation system, even after supplying it after filtering, the bio-flock breeding water containing a large amount of organic matter blocked the injection hole where the breeding water was injected, causing a number of failures. However, the cultivation water spraying apparatus of the present invention is primarily performed by a physical filtration process in a water storage tank, and by supplying the supplied breeding water in an atomized state, a separate filtration process using a filter material can be omitted, and the spray hole is blocked. You can solve the problem.

Currently, the aquaculture industry requires a system that is eco-friendly and energy-saving, and the present invention provides not only high-growth growth in a short period of time, but also eco-friendly farming by supplying the reared water from the biofloc farming system to the hydroponic cultivation system. As it is possible to operate and omit the purification process of installing the filter medium during the process of supplying the breeding water as cultivated water, it is not necessary to replace the filter medium, so it is possible to reduce the operating cost of fish farms and expand the farming base. There is industrial applicability by contributing to the development of the field.
