The operation of the present invention configured as described above will be described.

The first step of the present invention is a filtering process by the waste filter container 5 located in the lower water tank 4, and the seawater in the upper/lower water tank 3 and 4 is filtered through the waste filter container 5 .

In other words, as shown in FIG. 3, the seawater that has flowed into the waste filter container 5 is filtered by the filter plate 9 and accumulated in the waste collection chamber 8, and the seawater from which the waste is filtered is prevented from driving the circulation motor 6 Is transferred to the next step.

At this time, the impurity residue accumulated in the waste collection chamber 8 is removed by closing the lock valve 10 and opening the cleaning port lid 11 at the top, and the air introduced into the inlet 12 is removed from the inlet air separation chamber 13 It is collected in the air space 14 disposed above and is discharged to the outside through the air discharge pipe 15.

In addition, the filter plate 9 is arranged inclined in a wide upper portion and a narrow lower portion so that inlet air can be easily collected in the air space 14.

If air is introduced into the circulation motor 6, the air must be discharged to the outside through the air discharge pipe 15 since it is idle and causes a motor failure.

The second step of the present invention is a process of purifying seawater through a sterilization water purification device 1, and a sterilization water purification device 1 comprising an aeration chamber 16, a waste collection chamber 17, and a first biological filter chamber 18. ) To separate, discharge, and sterilize proteins in seawater.

That is, the seawater from which the debris has been removed through the first step is introduced through the inlet 19 installed on the side of the sterilization water purification device 1, and if necessary, the inflow amount can be adjusted with the inflow amount control valve 20.

The seawater from which the debris has been removed is introduced into the inlet 19 installed on the side of the sterilization and water purification device 1 through the debris filter container 5, and at this time, the amount of seawater inflow can be adjusted using the seawater inflow control valve 20. The air control valve 21 can be used to control the amount of air introduced, and the introduced seawater is mixed with air through the venturi 22 and injected into the multi-purpose cylindrical pipe 24 through the injection pipe 23. .

Therefore, in the multi-purpose cylindrical pipe 24, the seawater gradually rises from the lower part of the aeration chamber 16, but the upper part of the aeration chamber 16 has a structure in which the upper part of the aeration chamber 16 becomes narrower, so that the fine air bubbles rising through the multi-purpose cylindrical pipe 24 are pollutants in the seawater. It rises and is condensed while passing through the narrowed portion, and is collected in the waste collection chamber 17 through the bubble condensation pipe 25 and then discharged to the waste outlet 32.

Here, the seawater introduced into the multi-purpose cylindrical pipe 24 through the injection pipe 23 rotates the space between the outer 27 and the inner pipe 28 of the multi-purpose cylindrical pipe 24 as shown in FIG. It is mixed with air bubbles and ejected out of the multi-purpose cylindrical pipe 24, at this time, seawater is ejected toward the bottom of the aeration chamber 16 while colliding with the rising stop plate 29 attached to the upper portion of the inner pipe 28.

In this way, the multipurpose cylindrical pipe 24 maintains the residence time of the seawater mixed with the air bubbles in the aeration chamber 16 for a long time, so that the air bubbles discharge pollutants as much as possible.

At this time, the state in which pollutants are collected can be seen through a transparent observation tube disposed on the top of the sterilization water purification device 1, and the discharge rate of pollutants is controlled by the air control valve 21 connected to the venturi 22 and the inflow amount. The control of the valve 20 can prevent seawater loss due to excessive discharge of water bubbles.

That is, when the amount of foam discharged is excessive, the air control valve 21 is closed to reduce the amount of air injection, and if the amount of foam discharged is small, the air control valve 21 is opened to increase the amount of air injected.

As shown in FIG. 5, a sterilization lamp 33 is mounted above the lamp holder 30 in the multi-purpose cylindrical tube 24, and the sterilization lamp 33 includes a dust collection chamber cleaning tool lid 34 at the top and a lamp holder at the bottom. 30), so it can be easily removed.

In addition, there is a small drainage groove 42 in the lower part of the outer tube 27 and the inner tube 28 so that the water inside the tube is drained during cleaning, and the lighting status of the sterilization lamp 33 and the status of the aeration chamber 16 are checked. It can be observed through the window 35.

On the other hand, the seawater sterilized and purified in the aeration chamber 16 is discharged to the first biological filter chamber 18 through the conveying pipe 26, and the inlet of the conveying pipe 26 is adjacent to the bottom of the aeration chamber 16. It is arranged so that the seawater flowing into the transfer pipe 26 is purified once more while passing through the filter medium 36 and then discharged through the purified water outlet 37.

The third step of the present invention relates to a multi-stage biological filtration chamber system as shown in FIG. 4, wherein the seawater discharged from the water outlet 37 of the sterilization water purification device 1, which is the second step, is transferred to the second biological filtration chamber (2). ), and after purifying once more, it is supplied to the water tank through the water outlet (2d) disposed at the bottom of the second biological filter chamber (2), and if necessary, the tertiary biological filter chamber (40), or The above biological filter chamber can be further disposed, and clean seawater is supplied to the tank through the water outlet (2d) disposed at the bottom of the biological filter chamber in the final step.

In the first biological filter chamber 18, special materials such as activated carbon, volcanic sand, zeolite, etc. can be used as a filter medium 36 for removing odors in seawater or quickly improving turbidity. The effect of improving turbidity can be obtained.

Accordingly, purified and sterilized water is supplied back to the water tank through the purified water outlet 2d, so that seawater in a clean state can always be maintained in the water tank.
