Description

BACKGROUND OF THE INVENTION Field of the Invention [0001] The present invention relates to a biofloat sludge regulating apparatus and method for breeding heterologous living organisms,

The present invention relates to a method and a device for cultivating heterologous living organisms having a productivity increase effect through a cage which ecosystematically removes and regulates excess sludge generated in a biofracture mode by breeding organisms having different ecological positions in one space, The present invention provides a method and apparatus for controlling biofloat sludge through a bioflocculation method.

Korea's marine aquaculture can be classified into marine cage culture, onshore water tasting and festival ceremony, except for inland water culture. Of these, marine caged aquaculture is the largest and the supply of fish is also the largest.

In the case of marine cage culture, there are many factors that can not be controlled, such as typhoons, high temperature or low temperature, which are highly influenced by the natural environment. On the other hand, land-based aquaculture has little impact on the natural environment while cultivating on land or indoors, and is easy to control factors such as water temperature, dissolved oxygen, water quality and disease.

In the case of sea-aquaculture, there is a difficulty in breeding, and in the case of continuously returning the breeding water, it is difficult to expose to harmful bacteria and virus inflow when sterilization or filtration is costly or the filtration is not properly performed. Therefore, a recirculating aquaculture system (RAS) for filtrating and reusing the reared water and a Shallow Raceway System (SRS) for constantly feeding the reared water in a multi-layer water tank have been developed in the aquacultural aquaculture system. Biofloat technology, which is capable of decomposing pollutants and cultivating beneficial microorganisms in fish farms with fish, has gained popularity in recent years.

BioFloc technology is used to cultivate useful microorganisms and cultured species of heterotrophic bacteria and autotrophic bacteria and to cultivate ammonia in breeding water It is a method of cultivation that can decompose harmful organic by-products into fish and convert them into food that can be consumed by the aquaculture, as well as purifying the number of the breeding, thereby eliminating the need for rehydration or filtration in the aquaculture process.

Using biofloat technology, organic matter can be degraded about 10 to 100 times faster than algae degradation, which makes it possible to keep the water quality suitable for aquaculture. In addition, this technology can control the virus infection, etc. because it can make a closed breeding system that can prevent viruses, pathogens, and parasites from being introduced by water exchange during the aquaculture process, and to use the antibiotics It can be dramatically reduced. In addition, aquaculture can be cultivated in a controllable breeding facility on the land, so that any seasonal fish can be produced.

Biofloat technology, which can continuously produce environmentally friendly and clean food, is currently expanding its target species with white prawns, eels, yellow pheasant, mudfish and nidan koi, and it can supply eco- It also contributes to the income increase of the farm household.

As described above, the aquaculture using biofloat technology can increase the yield by densely packed breeding, prevent disease damage, facilitate the management of water quality in breeding water, and have a high feed efficiency, It takes time for microbial settlement suitable for cultured fish species and environment, increases oxygen supply for microorganisms and aquaculture fish, and it is necessary to control titratable acidity of breeding water. Especially, for the oxygen supply, the bubbles are continuously generated in the breeding water. Organic byproducts of bioflak are adsorbed on the surface of the bubbles and accumulate and accumulate along the breeding water.

Some of these biofloat sludges are decomposed by bioflavac microorganisms over time and are reduced to breeding water, but some of them are formed at the upper part of breeding water to form thickened cakes, which are disadvantageous in the cultivation process. That is, reducing the surface area of the water that is in contact with the atmosphere increases the oxygen input, and prevents exposure of cultured fish and autotrophic bacteria to light of appropriate illumination.

Therefore, in practice, bioflash sludge has been manually removed and removed. In this process, management costs have risen, and research and development on methods for reducing unnecessary occurrence of sludge generated in the bioflavicultural process in recent years .

FIG. 2 is a perspective view of a cage of a biofloat sludge regulating and culturing apparatus according to the present invention.
FIG. 3 is a schematic view of a bioflacture sludge regulating method according to the present invention.

In bioflavonoids, residual food, excrement, feed residue and degraded organic matter of fish or shrimp, which are the predominant organisms, accumulate in the breeding water, and microorganisms in the tank decompose after a lapse of time. However, in biofloat cultivation with high density, it constantly generates air bubbles in order to regulate acidity and supply oxygen. In this process, the organic byproducts suspended in the water which have not yet been degraded by microorganisms are adsorbed with air bubbles, It comes to mind. These biofloccal surplus sludges thicken over time, interfering with the supply of oxygen in the atmosphere and hindering the exposure of cultured and autotrophic bacteria to light of appropriate intensity.

Therefore, it is necessary to artificially hook biofloat sludge, and this process requires additional time and cost. In addition, recent studies have analyzed the components of Bioflak sludge and found that sludge from bioflak cultivation contains a large amount of useful ingredients that can increase the feed composition or growth and immunity of aquatic organisms.

Accordingly, the apparatus and method for regulating biofloat sludge through heterotrophic breeding of the present invention is more effective than the bioflocculation method in which only heterologous biologically located heterologous species are raised in the same space, The amount of surplus sludge is increased by increasing the speed, and the production per unit area is also increased through the cage considering the biological habit.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view of a device for regulating biofloat sludge according to the present invention. The present invention relates to a water tank (100) having a water tank bottom of a polygonal shape surrounded by an outer wall of a water tank and having an upper opening and an inner space, a mounting part (200) installed in the water tank opening, And a cage 300 separated from the cage 300 by a predetermined distance.

The aquaculture water tank 100 is a space in which biofloat aquatic organisms are accommodated and is suitably made of a corrosion resistant and durable material such as concrete, fiber reinforced plastics (FRP), polypropylene (PP), polyethylene (PE) At this time, the water tank should withstand the water pressure of the breeding water, and the outside of the water tank should be thick enough to not bend or damage. In addition, the scarf portion of the water tank can be formed in a curved shape so that solid organic matter is precipitated and not corroded.

Since water residue may accumulate on the bottom of the water tank and water quality may be deteriorated, a venturi device (110) for floating water is installed to spray oxygen to prevent stagnation of organic matter such as food and debris. And increase the amount of dissolved oxygen in the breeding water. In addition, a pump 120 capable of supplying breeding water is formed so that breeding water can be smoothly supplied to the water tank through the breeding water supply pipe 130.

The mounting portion 200 may have a structure in which one or more supporting rods are installed in the opening of the culture water tank and the upper portion of the supporting rods on which the horizontal member is installed is connected. As shown in FIG. 1, the horizontal member of the mounting part may have a "C" -shaped column shape passing through the upper part of the water tank, but not limited thereto, It can be used as a stand for separating the tank bottom and the cage.

Therefore, according to the user, the cage can be used as a mounting part by connecting a cage to a "ㅡ" type column, a ceiling, a part passing over the upper part of the water tank, and a rope like a rope can be used as a mounting part. If the buoy is used, the outer circumference of the cage may be connected to the buoy and floated on the surface of the water tank. The mounting part can be formed to cross the center of the aquaculture tank and to form pillars at both ends of the aquaculture tank. The rails can be installed on both sides of the aquaculture tank to move in the longitudinal direction, Horizontal movement across the channel allows the bioterror cage to be stationed at a specific location in the aquarium.

FIG. 2 is a perspective view of a cage of a biofloat sludge regulating and culturing apparatus according to the present invention. The cage 300 serves to isolate shellfish and echinoderms from the main breeding organisms such as fishes and shrimp in a water tank. In addition, the cage has a space with four side openings between the auxiliary cage and the auxiliary cage to provide space for living creatures such as shrimp, crabs, starfish, etc., Thereby increasing the production per unit area.

At present, the organism that is mainly cultured in bioflavons is a moist benthos living on the bottom of P. vannamei, and the production of benthic organisms is proportional to the increase in the area of attachment such as floor area. The bottom space is formed between the inner layer of the cage and the layer of the present invention, thereby increasing the habitat of the shrimp, thereby increasing the production per unit area and simultaneously accelerating the biological circulation rate to remove excess sludge.

The cage 300 comprises a cage frame 310 in which one or more auxiliary cages are accommodated, an auxiliary cage 330 for raising shellfish and echinoderms, and a binding body 320 for connecting the cage to the mounting portion. In the cage frame 310, a plurality of vertically and horizontally open polygonal frames are vertically connected to form at least one layer, and a support plate 311 is provided between the layers.

The support plate 311 supports the sub cage so that the sub cage can be stored in each layer in a stable manner. The support plate 311 can be formed as a net or a flat plate structure as a living space for tabular creatures.

It is appropriate to form the mesh of the support plate differently depending on the organism cultured along the layer of the cage. Shrimp, etc. The supporting plate of the layer intended to utilize the habitat space is formed of a dense mesh or flat plate to allow the sand, mud, etc. to be positioned, and the layer containing the shellfish such as shellfish can be raised So that the supply of floating food is smooth.

A tuck or a ring may be formed on one side of the cage frame to prevent the sub cage from falling down. A through hole may be formed through the upper and lower portions of the cage frame, or a ring may be formed on the upper side of the cage frame. The binding body 320 serves to fix the cage to a predetermined place by connecting the cage to the cage, and may be formed of a sling, wire, fiber, steel, or the like.

The auxiliary cage 330 is formed in a box shape of a polyhedron, and has upper, lower, left, and right sides of a net. This makes it possible to freely feed the water inside the auxiliary cage, so that it can provide food such as plankton and organic matter to the breeding creature inside the auxiliary cage.

The shellfish such as clam and the like eat plankton floating in water or organic matter that is dissolved in the water, so that it is preferable to use a coarse mesh outside the auxiliary cage 330 that houses the shellfish. On the contrary, it is preferable to use a dense network to store food on the floor, such as small creatures on the floor, or sea cucumbers that feed on organic matter in the mud sand.

In other words, the solid organic matter such as residual food excrement of fish is consumed by shrimp, and the shrimp excrement consumes shellfish and echinoderm (sea cucumber, lugwort, crab, open fire, high shellfish, etc.) as food and fish, shrimp, Ammonia and residues generated by echinoderms are degraded by microorganisms. In this process, microorganisms purify the water and produce proteins that will be consumed by the producer's food.

Accordingly, the apparatus and method for regulating biofloat sludge through heterotrophic breeding of the present invention not only controls the surplus sludge by promoting biological circulation but also accommodates heterologous organisms in a limited space, It is possible to increase the production amount per unit area of the breeding organism through the cage which provides the support plate used as the living space of the creature.

Hereinafter, the present invention will be described in detail with reference to the following examples of the method for controlling bioflavonable sludge through different breeding of the present invention, but the scope of the present invention is not limited by the examples.

Example  1: Through breeding of different species (shrimp and sea cucumber) Bioflack Sludge  Adjustment method

FIG. 3 is a schematic view of a bioflacture sludge regulating method according to the present invention. The present invention is characterized in that it includes a step (S100) of supplying biofloat, a step (S200) of stocking the main breeding organism, a step (S300) of stocking the cage, and a step (S400) of growing the main crop.

1) supplying bioprocess (S100)

The water used for biofrost cultivation should be a reservoir or sedimentation basin without disease carriers and disease sources. In the beginning of the bioflavonery form, first the shrimp in the tank is supplied with bioflavon which contains more amount of shrimp feed, mixed organic matter and microorganism than the actual food, so that the tank is similar to the bioreactor that promotes the proliferation of bacteria . Phytoplankton first flourishes first, and after 8 ~ 10 weeks, it is replaced by microbial flocs.

When the breeding water matures and becomes very stable, an environment is created that can degrade all the organic matter such as the large amount of feed to be administered. In this state, the content of ammonia is maintained at 2 ppm or less, the hydrogen ion concentration is generally maintained at 7.0 to 7.5, and the dissolved oxygen amount is maintained at 4.0 to 6.0 ppm.

2) a step of stocking the main breeding organisms (S200)

Shrimp, which is the main carnivorous organism of the present invention, will be described as an example. For shrimp farming, suitable water conditions should be between 22 and 30 degrees Celsius, with a dissolved oxygen content of at least 4 ppm, a salinity of at least 0.5%, a high concentration of Ca, and an alkalinity of at least 75 mg / l. Considering the above conditions, shrimp (main breeding organisms) are stocked in aquariums when the number of breeding stock is stabilized. After incubation little shrimp have passed about 35 days, it is advisable to stocking about 4kg ~ 7kg per 1m ² so 4g.

3) a step of stocking the cage (S300)

The sea cucumber as a heterologous organism other than the main carnivorous organism of the present invention will be described as an example. In the case of sea cucumber culture, suitable water conditions are more than 5ppm dissolved oxygen, sea cucumber is resistant to low salinity and suitable salinity is about 28 ~ 38%. The illuminance should be kept below 600 lux to avoid light-induced stress. Sea cucumbers are very strong in temperature adaptation ability and can grow normally in water temperature range of 0 ~ 20 degree, but should lower temperature when they exceed 28 degree. The cage containing celestial shells (shellfish and echinoderms) can be stored at any time after the stock is stabilized. The size of the sea cucumbers accommodated in the cage can also be adjusted by adjusting the density of the sludge Therefore, it can be used by being added or subtracted by the convenience of the user.

4) Growing step (S400)

In the breeding water used in the present invention, there are many floats originating from organic matter, which are formed by entanglement of microorganisms, phytoplankton, zooplankton, protozoan, nematode, organism and feed residue, It can be a good food for aquaculture.

Feed residue can be converted to a new natural organic material by environmentally beneficial microbial action and reused. Natural food and waste composed of various kinds of biogenic materials such as microorganisms can be used as food while forming a complex of organic material lumps. It is abundant and has a lot of low-molecular proteins, digestion is good, and natural immune strengthening function is given, so that it grows fast and can endure disease.

That is, organic debris such as excrement, feed residue, peeled shell, shrimp carcass, and residual food are continuously consumed by sea cucumber (shellfish and echinoderm). In addition, the bacteria absorb the organic or inorganic nitrogen dissolved in the excreta and sea water discharged from the shrimp and sea cucumber and turn it into a protein, which is a very useful natural food for shrimp and sea cucumber. In this process, the harmful nitrogenous waste is decomposed, Cleanse. Therefore, producers-consumers-decomposers within a tank form a symbiotic relationship, and no additional feed or feedwater circulation is required.

In order to maintain the biofrok system, the required conditions are DO 4 ppm minimum, mixed liquer suspended solid, mixed liquor suspended solid 300-500 mg / L, nitrogen C / N ratio 20 or higher, pH 6.8-7.2, alkalinity 100 ~ 150 mg / L should be maintained. In order to prevent the solid matter from sinking, aquariums, diffusers, air lifts, etc. are used to smooth the circulation of the breeding water and grow the breeding creatures.

When the breeding water stagnates, natural food and debris from the biofloat will form a mass of organic matter, accumulating on the bottom of the tank, rapidly depleting the surrounding oxygen, and producing toxic gases such as hydrogen sulfide, methane gas and ammonia, The air lift is mainly used to prevent this and maintain the proper amount of oxygen.

In order to solve this problem, in order to solve this problem, in order to solve this problem, it is necessary not only to control the surplus sludge by promoting biochemical circulation by breeding different species of biologically different species in the same space, It also has the effect of increasing unit output.

It is also possible to carry out sustainable cultivation in the same place with different biologically located heterologous species in the same space, not only because the feed is not required but also because the feed cost is reduced. In addition, maximization of resource utilization efficiency by minimizing occurrence of surplus bioflare sludge with high added value, maximization of farming efficiency by breeding with low cost and high productivity through cage for increasing rearing area, .
