Wastewater treatment system using the dissolved air flotation according to an embodiment of the present invention, the wastewater stored in the wastewater tank 100 and the chemicals stored in the chemical storage tank 200 to treat the wastewater into the mixing tank 300.

At this time, by the control unit 210 provided in the chemical storage tank 200, it is possible to efficiently treat the waste water by adjusting the chemical liquid input amount according to the state and the like of the density and amount of the waste water.

On the other hand, the waste water and the chemical liquid introduced into the mixing tank 300 is first mixed in a uniform state by the first stirrer 311 via the mixing unit 310, and the waste water and mixed by the first stirrer 311 The drug is supplied to the mixing unit 320 adjacent to the mixing unit 310.

Here, the waste water and the chemical liquid introduced into the agglomeration part 320 are stirred by the second stirrer 321 and are formed as flocs in the form of agglomerated matter by floating substances in the waste water reacted by the chemical.

In addition, the agglomeration unit 320 may be formed of a plurality of spaces so as to provide sufficient time for the waste water and the chemical liquid to react to form a floc while sequentially passing through the plurality of spaces.

On the other hand, the fluid with the floc is introduced into the waste water treatment tank 400 connected to the mixing tank 300, the waste water treatment tank 400 through the floc remover 410 provided on the upper portion of the waste water treatment tank 400 Floating flocks may primarily remove large flocs.

And, the water level sensor 530 automatically adjusts the water level inside the main body 510 to block the air supply of the interlocked air supply when the water level in the main body 510 is above the appropriate level, and when the water level is below the proper level, By allowing the air supply of the feeder to adjust the air supply in the main body 510 it is possible to efficiently provide air into the main body 510.

On the other hand, the fluid introduced into the body 510 through the inlet 550 delays the time that the fluid passes in the direction in which the fluid flows by the retardation plate 521 of the bubble generating member 520, the fluid is passed through Turbulence occurs due to the time difference, and the fluid collides with the retardation plate 521, and bubbles are formed by the impact.

Then, the fluid flowing through the delay plate 521 into the bubble generating plate 523 may pass through the bubble hole 524 formed in the bubble generating plate 523 to generate vortices, thereby forming bubbles in the fluid.

In this case, the fluid may pass through the bubble holes 524 having different sizes, as well as bubbles having different sizes, and turbulence may occur due to a time difference passing through the fluid, thereby forming a large amount of bubbles in the fluid.

In addition, since the fluid collides with the bubble protrusion 525 provided in the bubble hole 524, a large amount of bubbles may be formed by this impact.

In addition, a spiral portion 526 is formed on an inner circumferential surface of the bubble hole 524, and the spiral portion 526 is formed to have a different length or in a different spiral direction, thereby generating a difference in time or turbulence through which the fluid passes.

In addition, the bubble wing 570 provided in the outlet 560 rotates by the force from which the fluid is discharged, so that the fluid strikes the bubble wing 570, thereby forming more bubbles.

In addition, the heating unit 540 may increase the amount of fluid introduced into the saturated water tank 500 by increasing the amount of fluid introduced into the saturated water tank 500 by dissipating the bubbles supported by the upper portion of the saturated water tank 500 by heat.

As such, the fluid in which a large amount of fine bubbles are formed by the saturated water tank 500 is resupplied to the wastewater treatment tank 400 so that the fine floc is attached to the bubbles and floats on the surface of the fluid. The floc remover provided in the upper portion of the floc can remove the flocks to purify the waste water.

Therefore, in the wastewater treatment system according to the embodiment of the present invention, the fluid flowing into the saturated water tank 500 generates turbulent flow, thereby forming a large amount of fine bubbles, thereby improving wastewater treatment efficiency.

In addition, by generating a bubble by the impact that the fluid strikes the bubble wing 570, it is possible to form a large amount of fine bubbles to increase the wastewater treatment efficiency.

In other words, by forming the size of the bubble finely to increase the surface area of the entire bubble to prevent the collision between the rising bubbles to increase the flotation effect of the floc and the floc does not float in the fluid again to increase the removal rate of the floc waste Processing efficiency can be improved.
