Bioflac Aquaponics does not use antibiotics, pesticides, or chemical fertilizers, so it does not harm fish, and because it receives nutrients necessary for plant growth, it is possible to maintain a constant production of cultivated plants and does not throw away used water. It is possible to save agricultural water because it is supplied to fish and plants cyclically.

Various detailed technologies are being researched to realize aquaponics, and one of them, Biofloc Technology (BFT), supplies new aquaculture water by using excrement or feed waste from fish as food for useful microorganisms. It is in the limelight as an eco-friendly aquaculture technology that can be used again without doing it.

Regarding aquaponics using biofloat technology, various prior arts have been proposed, including Korean Patent Publication No. 10-2021-0017412 (Prior Document 1). However, conventional biofloat-based aquaponics technologies, including Prior Document 1, are more focused on fish growth, and after removing toxic components by applying biofloat to breeding water in a fish tank, some of them are sent to the plant cultivation facility at the rear. The content is to use it as cultivation water by supplying it.

However, the application of bioflac to fish manure alone cannot provide sufficient nutrients necessary for plant cultivation, so it is necessary to supplement this. There is no proposal for a variable providing technology.

<Example 1>

Example 1 relates to a hybrid aquaponics-based smart farm system supplemented with biofloat-aquaponics by additionally adding actinomycetes, microalgae, and useful microorganisms to a fish tank to which bioflac is applied.

1 is a configuration diagram of a hybrid aquaponics-based smart farm system according to Example 1.

The smart farm system of Example 1 includes at least one fish tank 10, a first culture tank 20, a second culture tank 30, a first mixing tank 40, a second mixing tank 50, and It includes a plant cultivator 100, a third culture tank 60, a fourth culture tank (not shown in the drawing), a fifth culture tank (not shown in the drawing), and a sixth culture tank (not shown in the drawing). ), at least one of a nutrient replenisher 70 and a recovery tank 80 may be further included.

The fish tank 10 cultivates fish by applying biofloc technology.

Ammonia and nitrous acid generated from feed residues remaining in the fish tank 10 and excrement of aquaculture organisms have a bad effect on aquaculture organisms due to their toxicity. Bioflac is a collection of microorganisms and small microbes floating in the water in the form of a cotton ball, and uses a carbon source to purify water quality by changing toxic ammonia and nitrous acid into bacterial proteins. In addition, bioflac itself serves as a food source for aquaculture organisms.

A plurality of fish farming tanks 10 may be provided, and at least two fish farming tanks may be stacked for space utilization. Although FIG. 1 shows a case where two fish tanks 10 are stacked, it is not necessarily limited to this, and the design can be changed to a single-layer or three-layer or more structure depending on the type, size, and amount of fish to be farmed. In addition, the upper fish tank and the lower fish tank are connected through an interlocking pipe (not shown in the drawing), and the lower or upper fish farm is equal to the capacity of the breeding water discharged from the upper or lower fish tank to the second mixing tank 50. The breeding water of the tank can be supplemented to the other party's fish tank through the interlocking pipe.

In the fish tank 10, freshwater fish such as eel, catfish, vannamei, etc. or marine fish such as flatfish, sea bream, yellow porpoise, etc. may be farmed, and it is not necessary to be limited to the exemplified fish species.

The first culture tank 20 cultures Actinomycetes, and the cultured actinomycetes are supplied to the first mixing tank 40 . The cultured actinomycetes may be directly supplied to the fish tank 10 or the second mixing tank 50 without passing through the first mixing tank 40 .

Actinomycetes are 98 types of microorganisms that live symbiotically in soil and refer to natural antibiotic microorganisms such as streptomycin caused by Streptomyces or kanamycin based on Kanmyces. When the actinomycetes are introduced into the fish tank 10, they combine with fish excretion to form a diverse group of antibiotic microorganisms as natural antibiotics, enabling antibiotic-free farming of fish. It is referred to as a hybrid biofloat in the sense that actinomycetes are added to the fish tank in addition to the conventional biofloat technology.

In order to activate the culture and proliferation of actinomycetes in the first culture tank 20, at least one of various microalgae including chitosan, seed cake and chlorella may be introduced into the first culture tank 20.

The second culture tank 30 cultures various microalgae to be introduced into the first culture tank 20 .

One of the microalgae of the second culture tank 30 may be chlorella. Chlorella is a type of plankton that is a green algae that lives in fresh water. Chlorella is rich in various vitamins such as about 60% of protein, chlorophyll, more than 30 kinds of fatty acids, and vitamin B group, so it enhances the immunity of fish and helps to purify the water quality of the fish tank (10).

Another of the microalgae of the second culture tank 30 may be Spirulina. Spirulina is a blue-green algae that grows in clean waters. Spirulina contains about 70% of protein, carbohydrates, soluble dietary fiber, essential amino acids, antioxidant enzymes, 12 vitamins and 10 minerals. It enhances immunity and helps to purify the water quality of the fish tank (10).

The first mixing tank 40 receives actinomycetes and microalgae from the first culture tank 20 and the second culture tank 30, respectively, and uniformly mixes the actinomycetes and microalgae.

The second mixing tank 50 receives the breeding water from the fish tank 10, and the first culture tank 20, the second culture tank 30, the third culture tank 60, and the fourth culture tank (drawing (not shown), the fifth culture tank (not shown), the sixth culture tank (not shown), and the nutrient replenisher 70 are mixed with the supplied breeding water to produce a cultivation nutrient solution. create Then, the nutrient solution for cultivation is supplied to the plant cultivator (100).

The third culture tank 60 selectively supplies useful microorganisms (Effectine Micro-organisms, EM) to the fish tank 10.

Useful microorganisms (EM) refer to a microbial complex in which microorganisms beneficial to the environment are combined and cultured using lactic acid bacteria, photosynthetic bacteria, and yeast as main bacteria. Beneficial microorganisms (EM) produce antioxidants, which are fermentation products, through complex coexistence and symbiotic relationships among microorganisms, and perform odor removal, water purification, organic matter fermentation, and the like.

The fourth culture tank (not shown) cultivates microorganisms that decompose chitosan and chitin, and the cultured microorganisms are transferred to the fish tank 10, the first mixing tank 40, and the second mixing tank. (50). Chitosan and chitin decomposing microorganisms decompose the eggshells of pests and chitosan and chitin, which are the main components of pathogenic fungi, and remove the causes of pests such as pathogenic fungi.

The fifth culture tank (not shown) cultures microorganisms that decompose gelatin, and transfers the cultured microorganisms to at least one of the fish tank 10, the first mixing tank 40, and the second mixing tank 50. supply one The gelatin-degrading microorganism decomposes gelatin, which is the main component that harms crops grown in the plant cultivator 100, and removes the causes of various diseases and pests such as nematodes, larvae, and egg sacs.

The 6th culture tank (not shown in the drawing) cultivates special microorganisms that improve and regenerate the water quality environment by decomposing fish bodies, excrement, solid substances, etc., and uses the cultured microorganisms in the fish tank 10 and the first mixing tank (40) and at least one of the second mixing tank (50).

The nutrient replenisher 70 supplies additional nutrients necessary for plant growth in the plant cultivator 100 to the second mixing tank 5 . The nutrient replenisher 70 may supply at least one of a specific organic trace element, an organic elicitor for functional ingredient enhancement, and a macro element such as MKP as an additional nutrient.

The 13 nutrients that plants need in aquaponics are N, P, K, S, Ca, Mg, Fe, Mn, Cu, Zn, B, Mo, and Al. Here, N, P, and K are macro elements, and S, Ca, Mg, Fe, Mn, Cu, Zn, B, Mo, and Al are organic trace elements.

Among the 13 types of nutrients, the commercially formulated feed introduced into the fish tank 10 lacks P (phosphate), Ca (calcium), K (potassium), Fe (iron), and MKP (potassium phosphate), so the It is necessary to artificially supplement the lack of nutrients for plant cultivation.

A bulk element such as monobasic potassium phosphate (MKP) can be supplemented through chemical fertilizers or by replacing it with other natural ingredients similar to potassium monophosphate.

A lack of Fe (iron) among organic trace elements causes pale or yellow leaves in young plants. In order to improve the functional components of cultivated crops, iron (Fe) content is quadrupled compared to conventional hydroponic cultivation, and zinc (Zn) ) can be increased eightfold.

The recovery tank 80 collects and stores the waste nutrient solution whose useful life has expired in the plant cultivator 100, and filters and purifies the recovered waste nutrient solution so that it can be recycled as breeding water. To this end, the recovery tank 80 includes a physical filter for filtering out solids contained in the waste nutrient solution, a chemical or biological filter for removing harmful components, an optical filter for sterilizing harmful microorganisms or harmful viruses, and removing solids using gas. and at least one of an ozone generator or an oxygen generator performing sterilization treatment. The waste nutrient solution filtered and purified in the recovery tank 80 is supplied back to the fish tank 10 through the circulation pipe.

The plant cultivator 100 is a device for cultivating crops in a hydroponic cultivation method.

1 illustrates a variable gravity rotating plant cultivator in which a cultivation bed is mounted concentrically on a circular or elliptical rotating body. However, the plant cultivator 100 does not need to be limited to the rotary type, and other hydroponic cultivation methods, that is, a conventional hydroponics cultivation system using a flat plate cultivation bed, a plurality of cultivation beds It can also be applied to vertical plant growers stacked on top of each other, rotating hanging plant growers in which a number of cultivation beds are suspended upward on various types of rotating bodies, and tower-type plant growers in which a number of cultivation ports are arranged obliquely in various places on a rod-shaped column. do.

In addition, the plant cultivator 100 may be arranged in a structure in which two or more plant cultivators are stacked. As a result, the rotary plant grower can secure more cultivation area per the same floor area compared to the vertical plant grower, uses relatively less water, and rotates while looking at the concentric axis of rotation, so by the action of the gravity cell It has the advantage of further promoting growth.

Although not shown in FIG. 1, the control panel controls the operation of the plant cultivator 100, while controlling the on/off or flow of control valves mounted on various pipes of the smart farm system.

<Example 2>

Example 2 relates to a case in which the connection structure of the third culture tank is changed in the smart farm system of Example 1.

2 is a block diagram of a hybrid aquaponics-based smart farm system according to another embodiment, in FIG. 2, the third culture tank 60 is connected to the second mixing tank 50 instead of the fish tank 10 Other than that, since it is the same as Example 1, redundant description is omitted.

<Example 3>

Example 3 relates to a smart farm system further comprising a camera and an analysis server in Example 1 or Example 2.

3 is a configuration diagram of a smart farm system according to Example 3.

At least one of a culture tank (not shown), a sixth culture tank (not shown), a nutrient replenisher 70 and a recovery tank 80 may be further included.

The fish tank (10), the first culture tank (20), the second culture tank (30), the first mixing tank (40), the second mixing tank (50), the plant cultivator (100), and the third of Example 3 A culture tank 60, a fourth culture tank (not shown), a fifth culture tank (not shown), a sixth culture tank (not shown), a nutrient replenisher 70 and a recovery tank 80 ) are the same as those of Example 1 or Example 2, so duplicate descriptions are omitted.

The plant cultivator 100 of Example 3 has some differences in that it further includes a camera C for photographing cultivated crops. The camera C captures images of crops under cultivation and transmits the captured images to the analysis server 110 via the control panel 120 or directly to the analysis server 110 .

The analysis server 110 receives the image of the crop from the camera C installed in the plant cultivator 100, finds the composition of the nutrient solution required for the current state of the crop based on the received image, and prepares the nutrient solution. The control information of the supply pipe for each nutrient of the nutrient replenisher 70 is transmitted to the control panel 120 .

By doing so, at least one of the growth stage and growth state of the crop may be determined. Specific examples of the growth stage include germination stage, growth stage, flowering stage, fruit stage, and the like, and specific examples of the growth state include leaf drying, growth sluggishness, yellowing, pest infection, and the like.

The query module 112 checks the nutrient information required for the current crop in a recipe database (recipe DB, not shown) based on the determination result of the analysis module 111. Here, the nutrient information may be information on the composition of nutrients necessary for the growth stage of the crop or the setting of the control valve for each nutrient supply pipe of the nutrient replenisher 70 matched to such composition, or for the growth of the crop. It may be information about the condition, for example, the composition of a treatment component for curing a condition infected with a specific disease or pest, or the setting of a control valve for each nutrient supply pipe of the nutrient replenisher 70 matched to such a composition.

The reporting module 113 transmits the nutrient information confirmed by the inquiry module 112 to the control panel 120 .

As a specific example, when the analysis module 111 analyzes the image sent by the camera C of the plant cultivator 20 and determines that the growth state of the crop is 'infected with leaf blight', the inquiry module 112 cures the leaf blight. Finding nutrient information, that is, the content ratio of sodium, potassium, calcium, magnesium, etc., or the control information of the supply pipe for each nutrient of the nutrient replenisher 70 to meet the content ratio, the reporting module 113 By providing the found nutrient information to the control panel 120, the control panel 120 controls the operation of control valves disposed in the supply pipe for each nutrient of the nutrient replenisher 70.

The control panel 120 controls the operation of the plant cultivator 100, and controls valves and pumps of various supply pipes, interlocking pipes, recovery pipes, and circulation pipes based on the analysis results of the analysis server 110. The control panel 120 may open any one of the control valves of the supply pipe for each nutrient of the nutrient replenisher 70 based on the analysis result of the analysis server 110, or may open two or more at the same time. In addition, the degree of opening of each control valve(s) may be differently controlled.

In the present invention, since various pipes allow only one-way fluid flow, control valves disposed in the pipes may include a function of a check valve to prevent flow in the reverse direction.
