In addition, the floating separation tank 20 is connected by the waste water stirring reservoir 10 and the connection pipe 40. The sludge collector 201 is installed inside the floating separation tank 20, and a skimmer device 200 is installed on an upper surface thereof.

In addition, the air supply device 30 is installed in the connection pipe 40 for connecting the waste water stirring reservoir 10 and the floating separation tank 20.

2 is a cross-sectional view of the air supply apparatus according to an embodiment according to the present invention, as shown in FIG. 2, the air supply apparatus 30 includes a connection joint 304, a case 301, and an auxiliary case 303. , A motor 300, an air suction pipe 302, and an impeller 305.

The connection joint 304 of the air supply device 30 is connected to and fixed to the connection pipe 40 and both ends by fastening members such as bolts.

In addition, the case 301 is installed in the center of the upper surface of the connection joint 304, the air inlet hole (301a) is formed in the upper end of the case (301).

In addition, the auxiliary case 303 is installed on the upper end of the case 301 so as to surround the outer circumferential surface of the case 301, and the lower surface of the auxiliary case 303 is opened to form an air inlet 303a.

In addition, the motor 300 is installed on the upper surface of the case 301.

In addition, the air suction pipe 302 is formed in the shape of the venturi tube is inserted into the case 301, the upper end is connected to the motor 300, the lower end of the case so as to protrude into the connection joint 304 301 is inserted into the inside, and an air inlet hole 302a is formed at an upper end of the air suction pipe 302.

In addition, the impeller 305 is installed at the lower end of the air suction pipe 302 to be located inside the connection joint 304.

Looking at the operation of the high speed flocculation flotation device according to the present invention with reference to Figure 1 and 2 as follows.

When the stirrer 100 of the waste water agitating reservoir 10 rotates at a high speed at 500 rpm to 5000 rpm, the waste water in the waste water agitating reservoir 10 is swirled to rotate along the inner circumferential surface of the waste water agitating reservoir 10. The waste water treatment chemicals introduced into the waste water agitating reservoir 10 are caused to generate strong agitation. That is, a strong centrifugal force acts on the wastewater by the high speed rotation of the stirrer 100, and the wastewater rises along the inner side from the bottom surface of the wastewater agitating reservoir 10 by this centrifugal force, so that the center of the wastewater agitating reservoir 10 is formed. There is a cavity is formed, and a strong whirlwind is formed due to the wastewater swirling up and down about the cavity, and many bubbles are mixed in the wastewater.

Wastewater in the wastewater agitating reservoir 10 in which a lot of bubbles are mixed by causing strong agitation with the wastewater treatment chemical as described above is introduced into the connection joint 304 of the air supply device 30 through the connection pipe 40. As the air supply device 30 operates, the wastewater introduced into the connection joint 304 naturally flows in the fine air particles outside the air supply device 30 to adhere to the solids or liquid particles in the wastewater.

That is, as the motor 300 of the air supply device 30 operates, the air suction pipe 302 connected to the motor 300 rotates, and as the air suction pipe 302 rotates, the air suction pipe 302. The impeller 305 connected to the lower end of the 302 is rotated. As the impeller 305 rotates at a high speed as described above, the wastewater inside the connection joint 304 causes stirring and at the same time the pressure around the impeller 305 is reduced, so that the air outside the air supply device 30 enters the air inlet. After entering into the auxiliary case 303 through the 303a, the air is introduced into the case 301 through the air inlet hole 301a, and the air introduced into the case 301 again returns to the upper portion of the air suction pipe 302. Is introduced into the air suction pipe 302 through the air inlet hole 302a formed in the air, the air introduced into the air suction pipe 302 is introduced into the connection joint 304 through the air suction pipe 302 It is incorporated with wastewater in the connection joint 304. At this time, in order to increase the treatment efficiency, a polymer coagulant supplying device tube (not shown) is attached to the air inlet 303a, and the polymer coagulant is introduced into the wastewater and reacted.

The wastewater reacted with the polymer flocculant is moved to the flotation separation tank 20 through the connection pipe 40, and the impurities in the wastewater with the waste water treatment chemicals and the polymer flocculant are agglomerated, and the waste water stirred storage tank 10 Bubbles mixed through the agitation process and the air supply device 30 adhere to the surface of the agglomerated skimmer to make the buoyancy large and quickly rise above the water surface.

At this time, the skimmer injured on the water surface is scraped by the scraper 200b mounted on the chain 200a which is rotated by the driving of the motor of the skimmer removing apparatus 200, and the skimmer recovery container provided at the upper side of the flotation separation tank 20 front side. 202 is collected.
