Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a sludge separating and removing device for bio-

The present invention relates to an apparatus for continuously separating and removing sludge from a farm site using a biofloat technique. More particularly, the present invention relates to a method for effectively separating sludge such as waste products or feed residue contained in biofloat breeding water at the same time as drainage, re-feeding the separated biofloat water to the aquaculture tank, A bioflavon sludge continuously separating and removing device capable of more efficiently utilizing bioflavable breeding water of a high value added.

BioFloc technology is used to cultivate useful microorganisms and cultured species of heterotrophic bacteria and autotrophic bacteria and to cultivate ammonia in breeding water Refers to a method of cultivation that does not require the return of water or filtration during the aquaculture by decomposing harmful organic byproducts into fish and converting the aquaculture into an acceptable food.

The cultured fish species using biofloat technology are increasingly being cultivated with white prawns, eels, wild boar, loach, nidan carp, etc. Especially, biofrost forms such as shrimp and eel are already in practical use. In a typical bioflavon farm, a water tank is enclosed by the outer wall of the water tank, and a water temperature regulator and a blower are installed inside the water tank. An air blower or circulating pump is essential for the water- .

Organic and microorganisms distributed in the breeding water are entangled with each other and sink to the bottom of the water tank if the water is not formed in the biofloat aquarium. In order to prevent this, in general, It uses a method of continuously dispersing organic matter and microorganisms.

BioFlag technology has the following advantages. First, organic matter can be decomposed at a rate of about 10 to 100 times faster than decomposition by algae. Second, on-land breeding facilities can control the environmental conditions and cultivate the aquaculture fish, so they can produce the aquaculture regardless of the season. Finally, it is possible to make a closed breeding system that can prevent the inflow of viruses, pathogens and parasites, etc. by the water exchange during the aquaculture process, so that it can control the viral infection etc. and greatly reduce the use of antibiotics . Therefore, it is possible to maintain the quality of water that aquaculture can survive, even if the number of breeding is almost not returned.

Most farms are aiming to generate high profits and want to ship large numbers of aquatic organisms in a short period of time. As a result, stocking of high-density aquatic organisms and increasing the amount of feed to be fed, waste products and feed debris can accumulate on the bottom of the tank. In order to decompose the settled sludge, microorganisms may be overloaded, so that the accumulated sludge can be discharged.

Since the amount of water that is drained usually accounts for 20-30% of the total amount of reared water, the drainage of indiscriminate reared water can lead to loss of operation of bioflak farm. In order to make biofloat breeding water, microorganisms suitable for farming species and environment are fixed, and biomass is adjusted according to type of fish and growth, so that it has high added value which requires a lot of labor.

In winter, energy consumption is increased due to the need to re-warm after supplying fresh water as much as the amount of drainage in the winter, and while the sludge is accumulated on the bottom of the tank until drainage work is performed, micro- Overload can occur. Therefore, it is necessary to develop a device capable of reducing the amount of drainage of breeding water as well as separating and discharging sludge and bioflocculation water.

In Korean Patent No. 10-1363623, there is disclosed a flow generating unit for supplying excrement and breeding water of a first breeding species and flowing along a circular trajectory, and a circulation supplying unit for circulating and supplying the excrement collected at the center of the bottom, RTI ID = 0.0 > biofloat < / RTI > including a feedback tube.

The present invention relates to a method for breeding sea buckthorn using biofloat capable of purifying and using the breeding water without exchanging seawater and fresh water of the breeding tank by producing and supplying bioflak after the megalopaing step. Korean Patent Registration No. 10-1270631 discloses a water tank system for a futuristic building-style aquaculture system in which a plurality of ecological niche (fish, shellfish, invertebrate, plant) are mixed in a natural ecosystem in a narrow space It is a water tank system that can regulate, produce and maintain environmentally friendly food such as reduction of feed and purification of water. It is a water tank system that feeds the remaining food and excrement during fish rearing, Discloses a complex aquarium for building aquaculture using biofloat capable of multitropic cultivation by hydroponic plants using nitrogen source in which microbes are dissolved and dissolved in shellfish and invertebrates. Korean Patent Registration No. 10-1508055 discloses that biofloat breeding water discharged from a fish culture tank of a water tank body is discharged to an auxiliary tank for cultivating tidal flat living creatures and used as a feed for ancillary aquatic organisms, Discloses a complex aquarium for biopharmaceuticals using a biological skimmer capable of culturing tidal flat creatures with abundant feed, organic matter, and minerals, while controlling the bioflavon concentration to a desired level by a biological method. However, the above-mentioned prior art has a microbial tank having an upper portion opened with a certain area and size, and a receiving space in which breeding water and sludge can be stored; A sludge separation unit connected to the aquaculture tank and capable of separating the sludge contained in the bioflocculation water drained; A microbial tank drainage pipe connected to the sludge separation unit to discharge the separated sludge to the outside of the microbial tank; In the microbial bath opening, there is not disclosed a configuration in which a breeding water inflow pipe is installed so that the separated biofloat breeding water can be re-supplied to the culture water tank.

With the goal of high-density and short-term shipment, sludge such as waste products and debris generated on the bottom of the tanks will need to drain about 20-30% of the total biofloat. However, the unreasonable drainage of Biofrock breeding wastes the high value-added biofloat breeding water, and in the winter season there is a problem that the burden of breeding farms becomes big because the new breeding water supply and the re-warming must be carried out in order to raise the lowered water temperature . In order to solve the above problems, the present invention provides a continuous sludge separation and removal device for bioflavon which can reduce the amount of water discharged from breeding water by separating biofloat water from sludge and increase the discharge of sludge.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described in detail with reference to specific configurations and accompanying drawings relating to the apparatus for continuously separating sludge for bioplastics.

1 is a perspective view of a continuous sludge separating and removing apparatus for bioplastics according to the present invention. The apparatus for continuously separating and removing biological sludge according to the present invention is provided with a microorganism tank (50) having an open top at a predetermined area and size and formed with a receiving space in which feed water and sludge can be stored; In the microorganism tank, a sludge separator (60) connected to a lower portion of the aquarium (30) and capable of separating sludge included in the drained biofloat water is installed; A microbial tank drainage pipe (51) connected to the sludge separation unit and discharging the separated sludge to the outside of the microbial tank; The microbial bath opening is provided with a breeding water inflow pipe 70 so that the separated biofloat breeding water can be re-supplied to the culture water tank.

The sludge referred to in the present invention is a size that can be judged by the naked eye and includes waste products or feed residue which are formed from aquaculture organisms and decayed when they are left for a long period of time and are usually stored for a long time in aquaculture tank, It means things that can cause our company.

The aquaculture tank 10 has a polygonal or circular water tank bottom and a water tank wall of a predetermined height formed around the bottom of the water tank and a space of a predetermined size is formed and the biofloat breeding water and aquaculture organism are stored . A water flow generating device (20) is installed on the inner side surface of the aqueduct tank wall. The water flow generating device may be installed vertically along the height direction of the water tank wall, and may have a pipe structure. On the side surface of the water flow generating device, an ejection hole is formed at regular intervals in the upward and downward directions.

In a conventional biofract style, if airflow or a circulation pump is installed and a constant flow of water is not formed in the water tank, organic matter and microorganisms distributed in the water may clump together and sink to the bottom of the water tank. The sinking organic matter and microorganism lumps are distributed only on the bottom of the water tank, so that the microorganisms may not be smoothly operated.

Biofloat breeding water and oxygen are injected into the water tank through a jet hole to form a water stream in a certain direction. In addition, the water pressure supplied to the formation of a water stream includes bioflocculation water, waste products and feed waste from aquatic organisms The sludge can be easily drained to the aquarium drain 30.

On the bottom of the water tank, a water tank drain 30 is installed. The aquaculture drainage port is connected to the microorganism tank transfer pipe (47), and the bioflocculated water and sludge drained can be transferred to the microorganism tank. The power for moving the biofloat breeding water to the microorganism tank can be supplied by the water flow formed in the water flow generation apparatus, but the microbial tank migration pipe can be provided with a water pump to supply the power. Also, it is possible to make a natural difference by having a difference in position between the aquaculture drain 30 and the microbial water tank.

The microbial tank (50) of the present invention has an upper portion opened with a certain area and size, and a receiving space in which the feed water and sludge can be stored is formed. The microbial tank (50) A moving pipe 47 is extended into the microorganism tank; A sludge separator (60) connected to one end of the microbial bath moving pipe and capable of separating sludge contained in biofloat breeding water; A microbial tank drainage pipe (51) connected to an end of the sludge separation unit and capable of discharging a trace amount of bioflocculation water and sludge to the outside of the microbial tank; A breeding water inlet pipe 70 is installed in the opening of the microorganism tank, and sludge is separated and the bioflocculation water stored in the microorganism tank can be reintroduced into the aquaculture tank.

Fig. 2 shows the microbial bath drainage pipe of the present invention. The microbial bath drainage pipe (51) of the present invention has a structure in which the upper part is closed, the lower part is opened, and the inside is empty. A sludge moving hole (51a), which can be connected to the end of the sludge separating part, is formed on the lower side of the microbial bath drainage pipe. The moving ball is usually formed with a diameter of 0.1 to 3 cm, but it may vary depending on the size of the water tank. This is to allow a small amount of biofloat breeding water to be discharged from the sludge transport pipe to be described later, which is connected to the moving ball.

The bottom of the microbial tank is provided with a drain hole 51b having a diameter capable of correspondingly fixing the opening of the microbial bath drain pipe so that the microbial bath drain pipe is inserted and fixed to open and close the drain hole. In general, when the bioflocculation water stored in the microbial tank is completely exchanged or when the water tank is washed, the microbial tank drainage pipe and the drainage hole are separated from each other and the breeding water is drained in a large amount.

3 shows the microbial crude sludge separator of the present invention. The sludge separation unit 60 of the present invention includes a separation pipe 63 for separating the sludge contained in bioflocculation water through a microbial bath migration pipe 47 and a fixed pipe 61, And a sludge transport pipe 62 connected to the microbial tank drainage pipe 51 at the other end to discharge sludge and a small amount of biofuel breeding water.

The separating pipe 63 has a downwardly inclined structure, and has a cut-away side surface. A separation net 63a is provided at the incision. The sludge contained in the biofloat breeding water can not escape, but the biofloat breeding water can be passed through the mesh.

It is appropriate that the microorganism bath moving pipe 47 is extended on the upper side of the microorganism tank. This is because one end of the separating pipe is connected to the microorganism tank moving pipe installed on the side of the microorganism tank and the other end is connected to the moving hole formed on the lower side of the microorganism tank water drainage pipe 51 so that the biofloat breeding water and the sludge move along the slope, So that the sludge can be easily discharged even if a separate underwater pump is not installed.

Biofloat breeding water and sludge drained from the aquaculture tank through the microorganism tank moving pipe are moved through the slope of the separating pipe while passing biofloat breeding water through the separating net and only the separated sludge is moved to the sludge moving pipe .

The sludge moving hole 51a connected to the sludge moving pipe is formed into a small-diameter through-hole structure in comparison with the existing drain pipe, so that the discharge amount of the biofloat-containing water can be reduced. Generally, the bioflocculation water discharged to the sludge transfer hole of the present invention forms a sludge transfer hole so as not to discharge about 0.5% or more of the total bioflocculation water capacity.

Sludge and biofloat water moved into the microbiological tank drainage pipe through the sludge transfer hole can be discharged to the outside of the microorganism tank through the drainage hole. The sludge separator according to the present invention separates and discharges the sludge not only after draining the sludge after accumulating the sludge in the water tank but discharging the sludge separately so that the sludge is piled up on the floor and the anaerobic condition is formed or the sludge is dissolved, Can be prevented from being excessively eluted into the breeding water to overload the microorganism decomposition function.

The bioflocculated water from which the sludge has been removed through the separation net can be stored in the microbial tank and re-supplied to the aquaculture tank through the feed water inlet pipe. It is possible to reuse biofloat breeding water, thereby preventing the waste of biofloat breeding water having a high added value from being irrevocably drained and making it possible to reduce the labor of making biofloat breeding water by forming new ponds, It is not necessary to re-open the water, which can alleviate the burden of operating the farm.

4 shows an embodiment of the microbial crude sludge separator of the present invention. The continuous sludge separating and removing apparatus of the present invention can continuously remove the biofloat breeding water and the sludge separately, but the sludge discharge can be controlled by installing the drainage regulating device 80 shown in FIG. 4 inside the separation pipe.

The drainage regulating device 80 includes a closing hole 81 accommodated in the separating pipe and formed to have a larger diameter than the sludge moving pipe to regulate sludge discharge by closing and opening the sludge moving hole. A connecting line (83) connected to the closed hole side in the form of a rope and having a length such that one end can extend to the outside of the water tank; And an adjusting ring 82 connected to the connecting line to adjust and fix the length of the connecting line.

It is preferable that the closed hole 80 is formed of a material such as rubber so that it can be submerged in water with a specific gravity larger than that of water and adsorbed to the sludge transfer hole by the discharge water pressure. When the sludge is adsorbed to the sludge transfer hole, the diameter of the sludge transfer hole is formed larger than the sludge transfer hole, and the sludge transfer hole can be closed without being discharged together with the sludge.

It is appropriate that the connecting line 83 is formed to have a length that can be extended to the water tank opening. One end of the connecting line is connected to the closing hole and the other end is connected to the adjusting ring. The control ring 82 has a fixing part formed to be fixed to the inside or outside of the upper part of the water tank. In the embodiment of the present invention, the adjusting ring 82 is formed so as to be fixed to the ring with a hook structure.

5 shows the working principle of the embodiment of the microbial crude sludge separator of the present invention. One end of the connection line may be connected to one or more control loops. The connection line shown in Fig. 5 is connected to the first control loop 81a and the second control loop 81b. Type 1 indicates that the first adjustment ring is fixed, and Type 2 indicates that the second adjustment ring is fixed.

When the first adjusting ring is fixed to the inner side or the outer side of the water tank, the connecting line is kept at the longest length in the water tank, and the closing hole is adsorbed to the sludge moving hole along the water stream, Is prevented from being discharged.

When the second control loop is fixed to the upper part of the water tank, the length of the connection line is shorter than that when the first control loop is fixed, so that the distance between the closed loop and the sludge moving hole becomes longer, The sludge can be continuously discharged by opening the ball.

For bioplaced Sludge  Installing the Separator Example  One

The apparatus for continuously separating sludge for bioflare according to the present invention can be connected to a culturing tank installed in a biofloack bioreactor for preventing massive biofouling, separately filed by the applicant of the present invention. 6 is a perspective view showing an embodiment of a continuous sludge separation and removal apparatus for bioplastics including a culture water tank equipped with an automatic spring water management device for preventing biofloacking of a biomass.

Bioproduct continuous bioflavon sludge continuous separation and removal equipment including a culture water tank equipped with biofloat biomass abolition prevention microfiltration management device has an upper part opened with a certain area and size and is capable of storing biofloccal microorganisms, A culture water tank 10 in which a receiving space is formed; A water generating device 20 installed on the sidewall of the aquarium so as to form a water stream in a predetermined direction; In the middle part of the aquaculture tank, there is installed a water tank 30 for drainage of breeding water and aquatic organisms requiring diagnosis, An automatic separation device (40) installed on the upper side of the aquaculture tank and connected to the aquaculture tank through a moving pipe to monitor the aquatic organisms requiring diagnosis; And a microbial tank (50) connected to the automatic separation device for separating and discharging sludge of bioflocculation water drained.

Fig. 7 shows an automatic separation apparatus for an automatic spring water management apparatus for preventing biofloacking of a biomass. The automatic separator (40) is provided with a bottom portion having a predetermined diameter and a cleaner plate (41) having a bottom portion surrounded by an outer wall and having an open upper portion. The cleaner plate top opening is provided with a cleaner plate bottom A video device 45 is installed so that the user can take a picture.

At the bottom of the cleaner plate, at least one separating hole 42 and a microbial bath moving port 43 are formed. The separation hole is connected to the end of the moving pipe, and the number of breeding water moved from the aquaculture drainage port and the aquaculture product to be a diagnostic specimen can be moved to the inside of the cleaner plate. The microbial communities can be connected to microbial communities and bioflocculated water and sludge can be drained into microbial communities.

In the inner space of the cleaner plate, a shut-off net formed of a diameter-sized net that can move only a few tens of millimeters is installed. The cut-off net is installed to divide the inside of the cleaner plate into two spaces. In the divided space, a separation hole is included, so that the number of breeding and specimen living creatures are inhabited. Only bioflocculation water and sludge permeated through the blocking net 44 are present. As a result, the microorganism can be drained into the microorganism group through the microorganism migration port, excluding the cultured organism.

In general, the creatures that are expected of our company will exhibit abnormal swimming and stopped motion. However, since the breeding water of Bioflag farm contains large amounts of useful microorganisms and organic matter, it is visually opaque and turbid, making it difficult to visually check the status of aquatic organisms underwater and cope with them.

Therefore, aquatic organisms which become diagnostic specimens to be moved together with the number of breeding can be separated by healthy flowering aquatic organisms and flow of water.

The imaging device is capable of capturing an image by identifying the aquaculture creature as a diagnostic specimen on the cleaner plate. It can count the aquaculture identified by the management system connected with the Biofrock automatic spraying water management device, Replacement of the water can be done automatically.

Biofrock breeding water is visibly turbid due to heterotrophic bacteria and organic matter, and it is difficult to observe the condition of aquatic organisms in the water. In addition, most aquatic organisms are active at the bottom of the aquaculture tank, There is a problem that it is difficult to grasp it. Biofloat bioprost bioseproducts are designed to isolate aquatic organisms that show signs of premature death when shrimp or eel are aquaculture, and automatically monitor the population of separated aquatic organisms Breeding water can be made. Therefore, by connecting the cultivated water tank equipped with the bioflocculation apparatus for preventing the biofloacking and the sludge separation apparatus of the present invention, it is possible to efficiently remove the sludge and regulate the volume of the reared water .

Sludge contained in biofloat breeding water with high added value can be removed at the same time as drainage and bioflag can be re-supplied to the aquaculture tank efficiently to reduce the cost of operation of the aquaculture farm, Can be widely developed, which is industrially applicable.
