1 to 5, the waste water reuse and oxidation disinfection facilities according to an embodiment of the present invention is a storage tank 10, a flow pump 20, an ozone water injector 30, an ozone dissolving tank 100 and ozone It includes a nozzle 200 for oxidation.

The storage tank 10 receives and stores waste water and ozone water, and discharges the purified treated water. To this end, the storage tank 10 has a waste water supply unit 12 and a treated water discharge unit (14).

Of course, the storage tank 10 can be applied in various shapes and materials.

The flow pump 20 serves to impart fluidity to the waste water by suctioning and pumping a portion of the waste water stored in the storage tank 10. In particular, the storage tank 10 and the flow pump 20 are connected by separate pipes to supply the wastewater of the storage tank 10.

In addition, the ozone water injector 30 receives ozone into the waste water that is forcibly flowed by the flow pump 20, and serves to discharge ozone water in which ozone is mixed with the waste water. At this time, ozone is generated by the ozone generator 32 and then injected into the ozone water injector 30.

 In addition, the ozone dissolving tank 100 serves to induce ozone to be dissolved in the waste water of the ozone water while increasing the residence time after introducing the ozone water discharged from the ozone water injector 30.

That is, the ozone dissolving tank 100 induces frequent collisions between the waste water particles and ozone particles of the ozone water injected by the ozone water injector 30 to dissolve ozone in the waste water.

To this end, the ozone dissolving tank 100 includes a body 110, a partition plate 120, a communication hole 130 and a tube 140.

The main body 110 is formed in a cylindrical shape to form the inner space 112, the inlet port 114 on the lower side along the axial direction, and the outlet port 116 on the upper side.

The inlet port 114 serves to allow ozone water discharged from the ozone water injector 30 to flow into the interior space 112, and the outlet port 116 serves to discharge ozone water flowing through the interior space 112. do.

Of course, the inlet port 114 is provided on the upper side in the axial direction of the body 110, the outlet port 116 may be provided on the lower side of the body 110.

At this time, the main body 110, the inlet port 114, and the outlet port 116 can be modified in various shapes.

In addition, a plurality of partition plates 120 are provided along the axial direction inside the main body 110 to partition the interior space 112 of the main body 110. For this reason, the partition plate 120 is welded while the entire circumferential surface is in contact with the inner surface of the body 110. Of course, the partition plate 120 is not limited to the number, material, and shape.

In addition, the partition plate 120 may be uniformly disposed along the axial direction in the inner space 112 of the main body 110, or may be intensively disposed on the upper side or the lower side.

In addition, the communication hole 130 serves to allow the ozone water flowing into the inlet port 114 through the plurality of partition plates 120 to the outlet port 116 side.

At this time, each communication hole portion 130 of the partition plate 120 adjacent in the axial direction of the main body 110 is not disposed in a straight line in the axial direction of the main body 110. That is, the communication holes 130 arranged in the vertical direction are arranged to be staggered with each other in the axial direction of the main body 110, so that the water level rises as the ozone water flows along the zigzag trajectory in the interior space 112 of the main body 110. .

In this way, the present invention is discharged from the ozone water injector 30, the ozone water introduced into the interior through the inlet port 114 of the main body 110 flows toward the outlet port 116 and collides and staggers the partition plate 120 By forming the zigzag flow path by the communication hole portion 130, the residence time in the ozone dissolving tank 100 is increased, thereby improving the dissolution efficiency of ozone in waste water.

In addition, the dissolution efficiency of ozone in the waste water becomes very high, so that when ozone passes through the nozzle 200 for ozone oxidation, it is prevented from being rapidly detached from the waste water and floating, thereby contacting the ozone particles with the waste water. Efficiency is increased, and purification of the wastewater through removal and oxidation of organic substances is effectively achieved in a short time.

On the other hand, the tube 140 is provided in each of the communication hole 130 so as to protrude to the upper side or the upper side of the partition plate 120, serves to increase the oxidation and cohesiveness between the ozone and the waste water particles of the flowing ozone water.

Each tube 140 displaces the flow of ozone water impinging on the corresponding partition plate 120 in the axial direction of the body 110, thereby guiding the flow, so that the dissolution and aggregation efficiency of ozone gas in waste water is further increased.

At this time, each tube 140 may be formed to gradually decrease in diameter (d1> d2) as the body 110 moves along the flow direction of ozone water. As the ozone water gradually passes through the tube 140 whose diameter decreases, the dissolution efficiency of ozone gas is further increased.

Of course, the tube 140 is not limited to the number, axial length and material.

In addition, along the flow direction of the waste water, the spacing of the tube 140 is not limited.

On the other hand, the ozone oxidation nozzle 200 is provided in the waste water supply unit 12, receives ozone water passing through the ozone dissolving tank 100 to induce atomization of ozone in order to increase the solubility of ozone in the waste water supplied from the outside. Plays a role.

At this time, it is assumed that the waste water supply unit 12 is a pipe, and the ozone oxidation nozzle 200 is detachably coupled to the end of the waste water supply unit 12.

Then, the waste water supply unit 12 is provided with an ozone water supply unit 16 to receive the ozone water discharged from the ozone dissolving tank 100. The ozone water supply unit 16 can be variously applied, such as a branch pipe branched from the waste water supply unit 12.

In particular, the ozone oxidation nozzle 200 includes a body 210, a cone-shaped collision member 220, a collision area increase member 230 and a supporter 240.

The body 210 forms an inlet 212 on one side along the axial direction to allow the waste water and ozone water flowing into the waste water supply unit 12 to flow in, and forms an outlet 214 on the other side. At this time, the body 210 may increase the amount of waste water and ozone water that is ejected to the outside by forming one or more jet ports 216 on the lower side of the circumferential surface.

Of course, the inlet 212, the outlet 214 and the outlet 216 may be variously formed, and is not limited to the number. The body 210 can be applied in various shapes and materials.

The cone-shaped collision member 220 is provided inside the body 210 so that the cusps 222 protrude toward the inlet 212, the ozone water flowing from the inlet 212 collides and is radially dispersed, so that the particles of the contained ozone are It serves to induce the outflow to the outlet 214 while increasing the solubility with the wastewater while being atomized.

That is, the cone-shaped collision member 220 is provided inside the body 210 serves to disperse radially the ozone water flowing into the inlet 212 collides. At this time, the ozone gas contained in the ozone water is oxidized (particulated) particles. As a result, the contact efficiency of the oxidized ozone gas with the waste water is increased, thereby improving the removal rate of organic substances and the purification efficiency of the waste water.

The collision area increasing member 230 is formed in a groove shape on an inclined circumferential surface of the cone-shaped collision member 220 to increase the atomization degree of the impacted ozone particles (gas). After the ozone water collides with the cone-shaped collision member 220, it flows along the collision area increasing member 230 formed in the circumferential surface to form a vortex. Thus, the ozone particles become more atomized, and the stirring force with the waste water is increased.

At this time, in order to increase the vortex flowability of the ozone water, the collision area increasing member 230 may be formed to be curvature toward the flow direction of the ozone water. Of course, the collision area increasing member 230 can be applied in various groove shapes and various numbers.

In addition, the body 210 is provided with a supporter 240 on the inner side, the cone-shaped collision member 220 is connected to the supporter 240 to be rotatable in the circumferential direction.

That is, in the conical collision member 220, the central axis 224 extending in the lower direction is inserted into the supporter 240, and the central axis 224 is rotated in the circumferential direction with respect to the supporter 240 by the bearing 242 It becomes possible.

In particular, as the collision area increasing member 230 is formed to be curved toward the lower direction, ozone water and waste water flow along the collision area increasing member 230 to form a vortex while the cone-shaped collision member 220 is circumferential. Is rotated.

Thus, as the ozone water and the waste water are sufficiently stirred inside the body 210, the ozone particles are dissolved in the waste water as much as possible.

In addition, the cone-shaped collision member 220 passes through a plurality of through-holes 226 along an inclined circumferential surface to pass a portion of the ozone water and a portion of the waste water, and the wing on the lower side to increase the solubility of ozone water to the waste water. And a member 228.

At this time, the through hole 226 may be formed in a hole shape on the cone-shaped collision member 220 separately from the groove-shaped collision area increasing member 230, but a part of the bottom surface of the collision area increasing member 230 is passed through It is supposed to be formed.

In addition, a plurality of wing members 228 are provided below the conical impact member 220. So, a part of the ozone water and a part of the waste water flowing into the inlet 212 pass through the through-hole 226 and cause vortex by the wing member 228. A portion of the ozone water passing through the through hole 226 and a part of the waste water are agitated with ozone water and waste water falling along the circumferential surface of the cone-shaped collision member 220, so that the solubility of ozone water in the waste water is maximized.

Of course, the wing member 228 can be deformed into various shapes.

As described above, the present invention is a plurality of partition plates 120 forming a collision and zigzag flow path of ozone gas and waste water after the ozone water dissolved in ozone gas (particles) in the ozone water injector 30 is injected into the ozone dissolving tank 100. By allowing the passage, the residence time in the ozone dissolving tank 100 can be lengthened and the dissolution efficiency can be improved.
