Hereinafter, a preferred embodiment of the present invention according to the accompanying drawings as follows.

First, FIG. 1 and FIG. 2 show the whole structure of the water treatment apparatus 1 which concerns on this invention. However, the wastewater, wastewater, or upper and sewage introduced into the water treatment apparatus 1 of the present invention are collectively described as W, and will be described in detail below while passing through the water treatment apparatus 1 of the present invention. The water treated by the water treatment means is described as W '.

For example, as shown in Figures 1 and 2, the water treatment apparatus 1 of the present invention, while the treatment water (W) is injected into the interior of the structure 10, the water treatment means 30 is installed therein It is characterized in that it is configured to improve the water treatment efficiency by increasing the contact time with the water treatment means 30 by increasing the residence time in the structure by inducing water flow.

Therefore, the water treatment apparatus 1 of the present invention is treated with water as the residence time is increased in the structure 10, such as a tank or a tank, by injecting the treated water (W) intentionally to induce the flow of water. The contact time with the means 30 is increased to increase the water treatment efficiency, for example, sterilization or aeration.

At this time, the water treatment apparatus 1 of the present invention is provided in the interior of the structure 10, but the water flow guide means 50 to guide the flow in the structure of the treated water (W) to increase the residence time It may further include.

It is configured to include a water treatment means 30 and the water flow guide means provided to the inside of the structure 10 to increase the residence time of the flow in the structure of the treated water (W).

At this time, as shown in Figure 1, in the water treatment apparatus 1 of the present invention, the structure 10 may be provided as one of the tank or tank of the cylindrical body.

For example, in the water treatment apparatus of the present invention, when the structure 10 is a cylindrical tank, the upper structure (tank) 10a and the lower structure (tank) 10b each of which the upper and lower portions are integrally sealed are respectively the water. It can be assembled in a watertight state through the flange (F) for the internal installation of the processing means 30, the discharge duct 16, the diffuser nozzle 36 and the like described later.

Of course, the inner surface may be a tank or concrete structure coated with a corrosion resistant resin even if not necessarily a synthetic resin tank.

At this time, as shown in Figure 1, the treatment water inlet pipe 12 is connected to the upper portion of the device structure 10, the discharge pipe 14 for discharging the treated water (W ') is perpendicular to the interior of the structure Is provided but the inlet (16a) is connected to the discharge duct 16 which is located under the structure, that is, the lower structure (10b).

Therefore, in the water treatment apparatus 1 of the present invention, since the treated water W introduced into the structure is introduced at the upper part of the structure, but the discharge is started at the lower part of the structure, the treated water is again passed through the lower part at least from the upper part inside the structure. Since it is discharged through the upper part of the discharge duct, the residence time in the structure is increased accordingly.

This improves the treatment efficiency through the water treatment means 30 described in detail below.

On the other hand, as shown in Figure 1, in the water treatment apparatus 1 of the present invention, the pressure control tube 18 may be further provided on the upper portion of the structure.

That is, the pressure control tube 18 of the present invention is connected between one or both of the structure 10 or the discharge duct 16 and the discharge pipe 14.

That is, the first pipe 18a vertically installed in the structure 10 and the second pipe 18b connected to the inside of the discharge duct 16 are connected to the main pipe 18c in contact with the atmosphere outside the structure. The main pipe 18c is connected to the discharge pipe 14 protruding out of the structure.

At this time, the main pipe (18c) in contact with the atmosphere may be further provided with a vent pipe 20 for discharging air.

Therefore, the pressure control pipe 18 of the present invention is emergency discharged externally when an overpressure is difficult to discharge the treated water (W) introduced through the inlet pipe 12 through the discharge duct only inside the structure. To provide the ability to

In addition, the vent pipe 20 provided at the main pipe of the pressure control pipe enables the air discharge of the air introduced through the air diffuser nozzle 36 introduced into the structure 10, which is a tank or a tank.

1 and 2, in the water treatment apparatus 1 of the present invention, the water treatment means for substantially treating the treated water W, that is, treated water such as wastewater, wastewater, and sewage ( 30 is a photocatalyst 32 coated on at least one of the inner and outer surfaces of the discharge duct 16 provided inside the structure, and in and outside the discharge duct to treat the treated water W in cooperation with the photocatalyst. UV lamp 34 installed on at least one of, that is, includes a UV lamp.

At this time, the ultraviolet lamp 34 is preferably installed perpendicular to the lamp socket (34a) is installed on the upper surface of the upper structure (10a) of the structure, it is preferable to extend as long as possible the length of the discharge duct.

The photocatalyst 32 may be coated on the inner and outer surfaces of the discharge duct.

Meanwhile, the UV lamp 34, which is the UV lamp, is a lamp in the form of a discharge tube formed by low pressure mercury vapor. As described above, the photocatalyst 60 which decomposes and removes VOC is known, but a representative one is dioxide. Titanium (TiO ₂ ) is used.

At this time, when the ultraviolet light through the lamp is irradiated to the treated water (W), the components of the nucleic acid cause chemical changes and lead to an inactive state resulting in loss of proliferative capacity, and finally, sterilization of the waste water, the photocatalyst 32 Is a substance that generates strong oxygen by light and promotes oxidative decomposition. It is known to be excellent in decomposing VOC and effective in removing antibacterial and odor.

On the other hand, the photocatalyst 32 may be simply coated on the inner and outer surfaces of the discharge duct 16 in the form of a spray.

Therefore, when the content of titanium dioxide (Tio ₂ ) is 3% or more, ultraviolet rays emitted from the working lamps of the photocatalyst 32, which are known to have an effect, cooperate to sterilize the wastewater and, in particular, oxidatively decompose the VOC to water and It is changed to carbon dioxide gas, and bacteria (bacteria) are also organic compounds.

For example, when ultraviolet rays irradiated from the ultraviolet lamp 34 are irradiated to titanium dioxide (TiO ₂ ) of the photocatalyst 32, OH radicals are generated on the surface thereof, and a substance adsorbed on the surface by the strong oxidizing power of the OH radicals. Disassemble it.

1 and 2, in the water treatment apparatus 1 of the present invention, the water treatment means 30 includes an air diffuser nozzle 36 disposed below the structure and the air diffuser nozzle ( 36 may further include a water supply gas supply pipe 38 for supplying one or both of air and ozone connected through the structure.

At this time, the water supply gas supply pipe 38 is further connected to the ozone supply pipe 42 via the air supply pipe 40 for aeration and the ozone lamp 44 branched thereto.

Therefore, in the water treatment apparatus 1 of the present invention, air, ozone, or these through the gas supply pipe 38 for water treatment through an acid nozzle 36 installed inside the structure through the bottom of the lower structure 10b of the structure 10. The mixed sterilizing gas is introduced into the structure, and thus, in addition to the ultraviolet + photocatalytic action described above, the aeration (acid) action increases oxygen dissolution rate or effectively sterilizes the treated water (W) with ozone.

That is, through the operation of the valves not indicated by a separate sign can be performed with the acid and the air and sterilization of the air and ozone through the air supply.

At this time, the sterilization of the treated water (W) through ozone is known, such ozone (ozone) is labeled as O 3 as the allotrope of oxygen, a slightly blue gas at room temperature, but when the liquid becomes black blue, solid It becomes dark purple, has a peculiar smell, and even if it is only 0.0002% by volume in the air, the smell can be detected.

In addition, such ozone is known to be used for purifying air and disinfecting beverages, bleaching, or determining the structure of organic compounds.

Thus, ozone purifies waste water by strong oxidative decomposition.

On the other hand, as shown in Figure 1 and 2, in the water treatment apparatus 1 of the present invention, the gas in the upper part of the acid nozzle of the structure, that is, air + ozone sterilization gas to the structure wall to guide the gas of the treated water It is preferable to further include a gas guide plate 46 to increase the contact time.

And, as shown in Figure 1, the gas guide plate 46 is a circular plate can be arranged on the top of the diffuser nozzle at the bottom of the lower structure (10b) through the fixing base (46a).

At this time, as shown in Figure 4, such a gas guide plate 46 of the present invention is preferably in the form of the upward curved to the outside to smoothly guide the inner wall of the structure of the gas.

That is, as shown in FIG. 4, when the guide plate is flat as shown in FIG. 1, gas induction of F2 is realized, but when the guide plate is in the form of an inverted hand lid curved upward toward the outside of the guide plate, F1 gas induction is realized. , It rises smoothly up along the inner wall of the structure, which improves its treatment efficiency, such as treatment water disinfection, since water is guided through the inner wall of the structure as described in detail below.

Next, the water treatment device 1 of the present invention induces the flow of the treated water (W) introduced into the structure 10 to flow through the lower inlet 16a of the discharge duct 16 while flowing from the upper portion to the lower portion. By doing so, looks at various embodiments of the water flow guide means of the present invention to increase the contact time with the water treatment means 30 described above.

First, as shown in Figure 2, in the apparatus of the present invention, the water flow guide means, the inclined connection to the structure to flow the treated water (W) flowing into the structure 10 toward the structure inner wall (10 '). It may be an inclined inlet pipe 12 '.

That is, when the structure 10 is a cylindrical body, the inclined inlet pipe 12 'of the present invention is connected to the inlet pipe 12 by using a flange (F), as compared to the pipe perpendicular to the structure wall. Thus, the flow of treated water flowing into the structure is guided to the inner wall 10 'of the structure.

At this time, preferably the inclined inlet pipe 12 'is installed toward the bottom of the structure, the treated water (W) discharged at a high pressure from the inlet pipe flows along the wall from the top of the structure to the bottom to guide the interior UV lamp and photocatalytic contact time is increased.

Next, as shown in Figures 1 and 2, another type of water flow guide means in the apparatus of the present invention, the inflow of the treated water (W) flowing through the treated water inlet pipe 12 is connected to the structure The water inlet 12a of the inlet pipe 12 may be curved to face the inner wall 10 ′ of the structure, or may be a curved pipe 50 connected to the inlet pipe 12.

That is, by installing a separate curved inlet 12a or the curved tube 50 in the structure can provide the same effect as the inclined inlet tube 12 'described above.

3a and 3b show water flow guide means 70 of the device of the invention in another form.

For example, as shown in Figure 3a, another water flow guide means 70 of the present invention is connected to the water inlet pipe 12 of the structure is attached to the inner wall of the structure body having a treatment water outlet 72a And a block type including an induction block 74 provided at the outlet 72a side to the inside of the body 72 to increase the flow rate of the inflowed treatment water and guide the treated water to flow toward the inner wall of the structure. It is characterized by being provided as a water flow guide means.

Therefore, when the treated water (W) is introduced into the body 72 to which the inlet pipe 12 is connected, the treated water increases in speed through the induction block 74 provided at the outlet 72a of the body, while the inner wall of the structure ( Water flow is implemented along the structure wall from top to bottom of the structure as it is discharged toward 10 ').

At this time, as shown in Figure 3a, because the induction block 74 has a larger tip portion than the rear end portion, the water outlet 74a between the actual induction block 74 is rapidly narrowed, and thus the treated water ( W) discharges the body outlet (72a) of the flow means while increasing the speed through the narrow outlet between the guide block.

Therefore, the treated water flows along the inner wall 10 'of the structure as much as possible, thereby increasing the contact time of the ultraviolet lamp 34 and the photocatalyst 32 vertically installed in and out of the discharge duct 16.

At this time, as shown in Figure 3b, the treated water outlet 72a of the body 72 of the block-type water flow guide means 70 is preferably curved to face downward from the top of the structure.

In this case, the treated water has a flow that is inclined from the top to the bottom of the structure but is guided along the inner wall to facilitate the discharge flow to the discharge duct while increasing the contact time of the water treatment means 30 of the treated water.

However, the block-type water flow guide means 70 of the present invention is the treated water (W) is supplied to the inside of the body 72 at a high pressure, because the outlet gap is suddenly narrowed to the induction block, the body and the induction block is firm. It is necessary to manufacture and install the structure to be combined.

And in the case of such a block-type water flow guide means 70 because the flow rate is increased by the narrowing outlet itself, the treatment water supply pressure may be a little lower than if only adjusting the direction of the outlet of the pipe, it is operating Will reduce costs.

While the invention has been shown and described in connection with specific embodiments so far, it will be appreciated that the invention can be varied and modified without departing from the spirit or scope of the invention as set forth in the claims below. It will be appreciated that those skilled in the art can easily know.
