Description

BACKGROUND OF THE INVENTION Field of the Invention [0001] The present invention relates to an apparatus for collecting and fermenting solids from a land farm,

In the present invention, at least two standpipes are arranged concentrically in the center of the aquaculture tank of the aquaculture farm so that the flow of the aquaculture water discharged from the aquaculture tank is formed into a zigzag flow in the upward and downward directions, The solid component is sucked and recovered from the solids collecting device for sedimenting and separating the components into the interior of the vacuum tank, and then dropped and stored in the fermentation tank containing the bubble dispersing device to ferment the product in the form of an organic acid sludge And to an apparatus for recovering and fermenting solid matter of an onshore farm.

In general, the aquaculture farms distribute and supply seawater pumped in the nearby sea to the aquaculture tank to perform aquaculture including aquaculture, and the aquaculture water discharged from the aquaculture tank is introduced into a solid collector and a biofilter, Most of the system consists of removing the solids (such as feed residue and excrement) and organic matter contained in the water and discharging it as the final effluent.

The solids collecting device for removing solids from the aquaculture water discharged from the aquaculture tank may be installed outside the aquaculture tank or may be installed inside the aquaculture tank in the form of a water level control tube, The outer pipe and the inner pipe in the form of a stand pipe are usually installed in a double pipe structure, the outer pipe is installed somewhat higher than the inner pipe, the inflow hole is formed in the lower side of the outer pipe, The lower end portion of the inner pipe serving as the final discharge passage of the aquarium is installed to penetrate the bottom plate of the aquarium.

Therefore, under the condition that the sea water is continuously supplied to the inside of the aquaculture tank, the number of the breeding water stored in the aquaculture tank is proportional to the supply amount of the sea water. In the course of raising the breeding water through the passage space between the pipes, a part of the solids contained in the raising water is settled down to the bottom of the water tank by its own weight.

However, since the sedimentation and separation performance of solids is extremely low, the solids collecting device for controlling the water level of the double pipe structure has a problem that most of the solids such as feed residue and feces are discharged to the outside of the aquarium, In the case of a higher level of contamination of the breeding water, an additional solid filter was installed outside the aquaculture tank, thereby causing a rise in the cost and facility of space utilization due to the facilities and operation of the aquaculture farm.

In order to solve the above-mentioned problems, the stand pipe, the precipitation inducing pipe and the outer pipe are arranged concentrically with a predetermined spacing around the inner pipe, A solid water collecting device with a built-in aquaculture tank built-in water level control device provided with a solenoid discharge device provided with an on-off valve is provided in the solids settling space on the bottom side to provide a stagnant breeding water flow passage and solids settling passage, Filed with the Korean Intellectual Property Office (KIPO) No. 17555 (No. 10-1288032).

As described above, since the sedimentation and separation performance of solids is very excellent despite the relatively simple structure of the solids collecting device combined with the water level control built-in by the present applicant, even if the contamination degree of the reared water is high, It is possible to prevent the solid component from being almost discharged and the sediment and accumulated solid component in the space can be discharged to the outside through the bottom of the water tank by using a pipe type discharging device installed in the solid sedimentation space.

However, even in the case of the prior art, there was a shortage in terms of collecting the solid components discharged from the aquaculture tank and fermenting them at a large capacity, and then using the same as food for microbial cultures cultivated in a biofilter on land farm or recycling as organic fertilizer. Since the discharge pipe of the solids discharge mechanism has a structure extending through the pipe structure of the solids collection device and extending to the bottom of the water tank, the installation work of the solids discharge device is difficult, and the solids collection device is separated from the aquarium There is a disadvantage in that it is not preferable in terms of smooth operation of the farm.
