1 is a view showing a filtration system 100 for multi-layered fish farming water according to the present invention.

Referring to Figure 1, the multi-layered fish culture breeding water filtration system 100 of the present invention is the upper portion is open inflow water is introduced into one side, the outer wall surrounding the tank bottom and the first outlet 111 is formed on one side of the tank bottom 1 filtered water tank 110; The upper part is opened and the inflow water filtered from the first filtered water tank 110 is introduced to one side, and a second outlet 121 is formed at the lower side of the outer wall and the other outer wall surrounding the bottom of the water tank, and the first filtered water tank 110. A second filtrate tank 120 positioned below; And at least one partition 130 installed in the first filtration water tank 110 and the second filtration water tank 120 and installed to allow the inflow water to pass up and down.

In the present invention, the first filtration water tank 110 and the second filtration water tank 120 may be made of a high-molecular compound having strong corrosion resistance and excellent durability.

In addition, the first filtrate tank 110 has an upper portion of which the inflow water is introduced into one side, and an outer wall surrounding the bottom of the tank and a first discharge port 111 through which the inflow water is discharged to the outside of the tank bottom are formed. do.

In addition, an upper portion of the second filtrate tank 120 is opened so that the inflow water discharged from the first outlet 111 of the first filtrate tank 110 flows to one side, and the outer wall surrounding the bottom of the tank and the lower side of the other outer wall. A second outlet 121 is formed through which the introduced inflow water is discharged to the outside.

In addition, the second bottom of the tank of the filtered water tank 120 may be further formed with a discharge port for discharging the wastes sank in the lower portion, the discharge port may be equipped with a discharge valve.

In the present invention, the second filtration tank 120 is located below the first filtration tank 110, so that the filtration tank is configured in a multilayer.

The filtration tank can be configured in a multi-layered form to improve space utilization, and to shorten the filtration time. Since the second filtration tank 120 is positioned below the first filtration tank 110, the inflow water filtered by the first filtration tank 110 is used to filter the filter medium 150 through energy generated due to a position difference at the time of discharge. It is assumed that the passage passes faster and the filtration time is shortened therefrom.

In the present invention, the partition 130 is provided with one or more so that the inflow water introduced into the first filtration tank 110 and the second filtration tank 120 passes up and down.
