The present invention relates to a water treatment device for microbial sterilization, disinfection, odor removal, decomposition of organic substances, etc. in water stored in a water reservoir, and more particularly, easy installation, installation, and maintenance by installing an ozone reaction tank in the form of a tower from the ground. The present invention relates to an advanced oxidation water treatment apparatus having a tower reactor for maximizing the dissolution rate and treatment efficiency of ozone by rising water flow.

Water such as tap water, drinking water, plant (vegetables) cultivation water, and food processing water may not only contain various contaminants that have not been removed during the purification process, but may also be stored in a transfer process or storage tank. Since there is a possibility of secondary contamination due to infiltration of harmful substances from the aging water supply pipe, it is necessary to use the raw water supplied after undergoing water purification treatment such as sterilization and purification without using the raw water as it is.

Conventionally, high-oxidation purified water treatment technique that can thoroughly remove environmental hormones and carcinogenic trihalomethane (THM) as well as thoroughly sterilize bacteria and viruses in water by using ozone gas (O ₃ ) and ultraviolet rays among water treatment methods. (AOP (Advanced Oxidation Process) technique) is known.

The above-described highly oxidized water treatment technique, when ozone gas is irradiated with ultraviolet rays of special wavelength, ozone is separated into oxygen and free oxygen, and free oxygen is sterilized. It exerts its oxidizing power and sterilizes dissolve spores, viruses, and bacteria in water, while oxidizing and removing inorganic substances such as iron, manganese, ammonia and cyanide, removing odor-causing substances, and removing organic substances such as phenol and pesticides. strong oxidizing agents via the hydroxyl radical (OH ^-) formed by the oxidation treatment to decompose the organic matter in the water decomposition, sterilization, deodorization, bleaching, and other hazardous materials.

As a water treatment apparatus using such a highly oxidized water treatment technique, as in Korea Utility Model No. 0137236 and Patent No. 0050650, a water treatment apparatus in which an ozone generator including an ultraviolet lamp is directly introduced into a reservoir ( Hereinafter, a separate reaction tank including an 'internally charged water treatment device' and an ozone generator having an ultraviolet lamp as described in Korean Patent No. 0419828 may be attached to the top of the reservoir or attached to the ceiling of the top of the reservoir. Known forms of water treatment equipment (hereinafter referred to as "ceiling-mounted water treatment equipment") and the like.

Among them, the internally charged type water treatment apparatus has a structure in which ozone mixed bubbles rise to the upper part of the stagnant water as soon as they are generated at a portion adjacent to the bottom of the reservoir, and are discharged and discarded out of the apparatus. The use efficiency and treatment efficiency of ozone gas is inevitably low. In addition, the ozone generating device and its related devices are large in size and costly to manufacture and install, which leads to uneconomical disadvantages.

In addition, since the entire internal ozone generating device is formed in a form in which the entire ozone generating device is immersed in the water tank (water tank), it is difficult to know the operation status inside the water tank, and thus it is difficult to secure the reliability of the water purification and maintenance. In the city, the entire operation of the ozone generating device from the water tank, but also to the upper portion of the high water storage tank, has to be lifted, which is inconvenient and expensive.

Such a ceiling-mounted water treatment apparatus is a type in which the reactor 10 is partitioned into three regions by partition walls so that water and ozone are supplied from the first region and overflowed to the opposite region, but in reality, the first region is used. The amount of ozone gas injected into the second zone along with the water is not so much but rises as it is and stays in the upper space. Therefore, since the injected ozone gas is released after staying in the water only in the first region, the utilization efficiency of the ozone gas is low, and thus the treatment efficiency is low, and the scale of the ozone generating device and related devices will be larger than the treatment capacity. There was no choice but to.

In addition, since the reaction tank and the auxiliary device are installed on or near the ceiling of 4 to 5 m high, construction and maintenance are difficult and expensive, and there is a disadvantage in that sufficient space for maintenance is also required. Or you can't figure out the operation status of the equipment while standing on the floor of the machine room, and sometimes rely on the ladder to check and check the water purification reliability is low, and it is difficult to cope with the sudden situation such as failure.

On the other hand, the air supplied from the air pump 70 is supplied to the air supply header 320 installed on one side of the ultraviolet sterilization and ozone generator block 300, and then through each of the ultraviolet lamp unit (322) the ultraviolet lamp unit ( It enters between the quartz tube 311 and the ultraviolet lamp 312 of 310. As described above, oxygen in the air flowing between the quartz tube 311 and the ultraviolet lamp 312 is changed to ozone by a special wavelength of ultraviolet light emitted from the ultraviolet lamp 312. In this manner, ozone gas (air containing ozone gas) generated in the plurality of ultraviolet lamp units 310 is collected into the ozone trap header 330 through the ozone branch pipe 332, and then the connection pipe 221 is removed. Water is supplied to and supplied to the bubble diffuser 220 installed in the bubble diffuser block 200. In the bubble diffuser 220, ozone gas is ejected in a fine bubble state and rapidly mixed with water to disinfect bacteria, viruses, etc. in the water, to remove inorganic substances, to remove odors, to decompose organic substances, to decompose chlorine ions and trihalo. Water reactions such as the removal of methane (THM).

As such, the fine ozone bubbles supplied to the bottom of the reactor 100 are rapidly mixed with the incoming water and gradually pass through the ultraviolet sterilization and ozone generator block 300 while naturally rising along the rising water. Ozone bubbles passing through the UV disinfection and the ozone generating unit block 300 includes a hydroxyl radical (OH ^-) having a strong oxidizing power causing the same AOP reaction as has been described above by the ultraviolet light emitted from the UV lamp and generates, this hydroxyl radical is Through UV sterilization and ozone generator block 300, reaction extension block 500 and discharge block 400, kill various viruses, microorganisms and harmful bacteria in the water, and oxidize and decompose THM and organic materials Will produce clean water.

On the other hand, since the plurality of flexure plates 520 are installed at a predetermined interval in the reaction extension block 500, water and ozone bubbles are bent along the flexure plates 520, thereby preventing the occurrence of ozone bubbles. The residence time and travel distance in the water are further extended to maximize the treatment efficiency and effectiveness. In addition, when the water purification material 530, such as tourmaline, elvan, or softening resin, is filled in the space between the curved plates 520, it is possible to provide water of a quality suitable for the needs of the consumer.

The water purified through the water introduction and bubble diffusion block 200, UV sterilization and ozone generating block 300, the reaction extension block 500 and the discharge block 400 is discharge block 400 It is transferred to the reservoir 20 through the treated water discharge port 410 of the).

On the other hand, an undissolved ozone bubble, i.e., an excess ozone bubble, remains in the upper portion of the discharge block 400, and the surplus ozone bubble is an excess ozone gas discharge outlet 420 and an excess ozone gas supply pipe 421. Since it is connected to the water inlet pipe 210 for supplying the water to the reaction tank 100 for the first time through, the ozone gas once used is used again.

For example, since ozone gas has a very low solubility in water, it does not sufficiently dissolve in water in one reaction. In the present invention, such surplus ozone gas can be used again and again, so that even with a small amount of ozone gas, the maximum water treatment effect can be obtained. In addition, for this reason, it is possible to reduce the size of the ozone generating unit and related auxiliary devices, such as to reduce the overall overdesign of the water treatment device and to reduce the waste of ozone and to operate efficiently.

Here, a venturi injector 211 is installed in the water introduction pipe 210 at a portion to which the surplus ozone gas supply pipe 421 is connected, and the surplus ozone gas supply pipe 421 is provided at the venturi injector 211. You are connected. Accordingly, a negative pressure is formed inside the excess ozone gas supply pipe 421 at the speed of the water passing through the venturi-type injector 211, and by this negative pressure, the excess ozone gas is introduced into the venturi-type injector 211. Aspirated, finely bubbled while passing through the venturi-type injector 211 and rapidly mixed with the water into the water introduction and bubble diffusion block 200, and purified by the process described above.

Although specific embodiments of the present invention shown in the accompanying drawings have been described in detail above, this is only one example of a preferred embodiment of the present invention, and the protection scope of the present invention is not limited thereto. Therefore, the embodiments of the present invention as described above are capable of various modifications and equivalent other embodiments by those skilled in the art within the technical spirit of the present invention, such modifications and equivalent other embodiments are the present invention It is obvious that the claims belong to the appended claims.

As described above, according to the high oxidation oxidation treatment apparatus having the tower reactor according to the present invention, since the reactor is formed of a long tower type, fine ozone bubbles are generated at the bottom of the reactor and slowly float to the top to react with ozone gas. The reaction residence time is very long, thereby producing a high-efficiency AOP reaction to maximize water purification efficiency such as sterilization, oxidation, and odor removal. Further, for this reason, it is possible to provide a water treatment apparatus that is far superior to any water treatment apparatus known to date.

In addition, since the reactor forms a form extending from the bottom of the water tank chamber (floor construction), construction and installation are easy, occupy a small installation area, and are less restricted by the installation site or location, and operating conditions inside the reactor outside. It is easy to maintain and at a glance, and it is possible to quickly grasp the situation such as failure and cope quickly so that the reliability of water purification is secured.

In addition, since the reactor is installed and operated at the bottom of the water tank chamber, it is not necessary to enter the water tank during maintenance or regular parts replacement work or work in the ceiling of the high altitude, thereby enabling very efficient management.

In addition, since the once-used ozone gas can be used again and again, the efficiency can be maximized and the scale of the ozone generator and its peripheral device can be reduced.

In addition, since the ultraviolet lamp unit is made of a detachable coupling structure, the construction is convenient, and the replacement and maintenance of the ultraviolet lamp is very convenient.

In addition, since the tower reactor has a structure in which each block is separably stacked, there is a convenience that assembly (installation) and disassembly can be easily performed, and that each block unit can be replaced.
