Description
BACKGROUND OF THE
Generally, aquatic products such as fish are cultured in a water tank. In such a tank, breeding water is discharged through an outlet provided on the floor, and the discharged water is supplied to the tank after the purification treatment.
These aquaculture systems are used to grow fish in the aquarium, so they can be contaminated with toxic gases such as excrement from fish metabolism, feed residue remaining in water, ammonia, and secondary nitrogen generated from their decomposition have.
Therefore, in the aquaculture system, filtration of the stock water stored in the water tank is an important factor.
In addition, the aquaculture system generally includes a filter unit for filtering wastes remaining in the water, excrement of fish, an aeration unit for supplying oxygen to the water tank, an ammonia treatment unit for treating ammonia contained in the water for breeding water, or an ozone supply unit .
Therefore, the water quality such as Biochemical Oxygen Demand (BOD) can be maintained above a certain level through the aquaculture system.
However, such a conventional circulating filtration and filtration system has a problem that the filter medium is clogged or agitated in a state in which the filter medium is immersed in water, so that the filtration medium is clogged or the oxygen is not uniformly supplied, thereby causing the filter medium to be corrupted.
Further, since the filter medium is always in a state of being submerged in water, there is a problem that the filtration ability decreases with time.
SUMMARY OF THE INVENTION Accordingly, it is an object of the present invention to provide a circulating filtration system capable of improving the processing efficiency by improving the structure of the aerobic and anaerobic filtration tank to purify the breeding water discharged from the water tank, System.
In order to achieve the above object, a circulation filtration system according to an embodiment of the present invention includes a
A water collecting tank (5) for storing foreign matter discharged from the water tank (3) and separated into an upper layer and a lower layer by a specific gravity difference; And
The
As described above, the circulation filtration system according to the embodiment of the present invention has the following advantages.
First, by arranging the aerobic filtration tank and the anaerobic filtration tank integrally at the upper and lower portions, the breeding water discharged from the water tank can be subjected to the aerobic treatment first, and then the second anaerobic treatment can be performed efficiently. .
Second, a plurality of stringy filter media are arranged inside the aerobic filtration tank in a vertical direction, and water is sprayed on the cord material to cause the aerobic process to proceed by flowing down in contact with the surface of the string bonin material in which the aerobic microorganisms reproduce In this process, the flow rate is slowed by the friction with the filtration body, and the time for contact with oxygen is increased by slowing the flow rate, so that the dissolved oxygen amount is increased.
Third, since a plurality of strap materials are not immersed in water, but are exposed to the inner atmosphere of the aerobic filtration tank, it is possible to prevent the decaying phenomenon or clogging caused by the filtration material being submerged in water.
Fourth, by disposing an auxiliary drain pipe provided with a screwdriver on the bottom of the water tank, and spraying air through the air supply pipe to the filter net, foreign matter can be prevented from adhering to the net, and drainage can be smoothly performed.
Fifth, the distilled water stored in the water collecting tank is separated by centrifugal force, and the foreign matter having a large specific gravity forms a downstream layer, and the foreign matter having a small specific gravity forms an upstream layer and is separated from each other.

In this process, the foreign substances contained in the breeding water can be separated into the upper and lower layers due to the difference in specific gravity. That is, the foreign matter having a small specific gravity stays in the upstream layer, and the foreign matter having a large specific gravity stays in the downstream layer.
In this state, when the first pump (M1) connected to the water collecting tank (5) is driven, the foreign substances in the downstream layer are supplied to the filtration unit (7) through the first pipe (L2). The foreign matter in the upper layer may be supplied to the sterilizing portion through the second pipe L3 when the second pump M2 is driven.
