Description

UV and ozone generating AOP chamber and water treatment device using same {UV AND OZONE PRODUCING AOP CHAMBER AND WATER-CLEANING APPARATUS USING SAME}

The present invention is an AOP chamber (Advanced Oxidation Process Chamber) that can be installed outside the tank to sterilize harmful microorganisms in water using ultraviolet rays and ozone generated therefrom, decompose and purify organic matters, and cause deodorizing effects, and It relates to a new water treatment device used.

Background Art In recent years, ultraviolet lamps have been widely used for sterilizing, purifying microorganisms in the air or in water, and decomposing organic substances that cause odors. Ultraviolet rays are light with a wavelength in the range of approximately 0.1 nm to 400 nm and have a relatively high energy. When irradiated directly to the cell membrane of a microorganism, the ultraviolet ray destroys the cell wall or cell membrane of the microorganism and destroys its DNA or inhibits its proliferation. Has the effect of sterilizing. On the other hand, ultraviolet rays are known to cause no harm to humans except to irritate the eyes or skin, and require sanitary facilities, such as restaurants and livestock barns, storage warehouses, food factories, aquariums, purification plants or hospitals. UV lamps are installed and used.

On the other hand, ultraviolet rays also excite oxygen to generate ozone (O ₃ ). Therefore, the ultraviolet lamp has not only a sterilizing effect by ultraviolet rays but also a sterilizing, purifying and deodorizing effect by ozone generated by ultraviolet rays. The ultraviolet and ozone act at the same time to have a sterilization, purifying and deodorizing effect is called the sterilization and deodorization by the advanced oxidation process (Advanced Oxidation Process). Therefore, the sterilization, purifying and deodorizing action using the ultraviolet lamp uses the principle of the advanced oxidation method, and the sterilizing, purifying and deodorizing effect can be said to depend on the generation of ultraviolet rays and ozone and their utilization efficiency.

Conventionally, devices for sterilizing and purifying aquatic microorganisms using such ultraviolet lamps are known. For example, Patent Publication No. 2000-29946 (The Regent of the University of California) for "Ultraviolet Water Sterilization Apparatus" describes a gravity-driven feedwater distribution system and a laminar flow of water flow downstream of the feedwater distribution system. A baffle wall with through holes, an ultraviolet lamp suspended in the air and exposed, an inclined treatment chamber provided below the ultraviolet lamp downstream of the baffle wall, and an outlet weir provided at an end of the inclined treatment chamber. Disclosed is an ultraviolet sterilization apparatus comprising: The sterilization apparatus is characterized by laminar flow of the water to be treated, and through the narrow passage to irradiate ultraviolet rays and then sterilize the sterilized water from the chamber, thereby more efficiently hydrodynamically sterilizing.

On the other hand, Patent No. 149049 related to "Highly purified water treatment apparatus and method thereof" (except the above) generates organic matter decomposed substances of OH radicals using ozone provided from an ozone generator and ultraviolet rays from an ultraviolet lamp installed inside. Thus, the primary water treatment unit for sterilizing the contaminated water, and the secondary water treatment unit for adsorbing the remaining pollutants by adsorbing the untreated pollutants in the primary water treatment unit by the adsorption means of granular activated carbon. It provides a high water purification apparatus comprising a backwashing unit performing a backwashing action between the first water purification unit and the second water purification unit, and a third water purification unit that is sterilized again using ozone. do.

In addition, many kinds of water treatment apparatuses using ultraviolet rays are known. However, these conventional water treatment apparatuses using ultraviolet rays mainly use only the sterilization effect by ultraviolet rays generated from the ultraviolet lamp, and can simultaneously bring about the sterilization and purification effect by ozone by converting oxygen in the air into ozone by the ultraviolet rays. Nothing was developed as an effective device.

The bactericidal effect by ultraviolet light and the ozone generating effect using the same are well known. Therefore, sterilization and deodorization apparatuses that utilize both ultraviolet sterilization and deodorization effect by ozone generated by using an ultraviolet lamp to sterilize and deodorize livestock livestock, etc., are not known. As described above, however, no water treatment apparatus using an ultraviolet lamp is known as an apparatus for sterilizing, purifying and deodorizing water by using ultraviolet rays and ozone generated therefrom at the same time and more efficiently.

The present invention has a first object to provide a new ultraviolet and ozone generating device using an ultraviolet lamp, which can be used in a water treatment device and can maximize not only ultraviolet light but also ozone generating effect.

It is a second object of the present invention to provide a novel water treatment apparatus which can fully utilize the ultraviolet and ozone sterilization effect simultaneously using the ultraviolet and ozone generators.

A third object of the present invention is to provide a new water treatment apparatus that can maximize the ultraviolet and ozone generating effects by the ultraviolet lamp and use them more efficiently, without a separate ozone generator.

The treated water passes into the quartz tube 12, and both ends of the quartz tube are open for this purpose.

Although the figure shows that two identical ultraviolet lamps are installed, one longer ultraviolet lamp may be installed along the entire length of the housing. Preferably, the inner wall of the housing is coated with an aluminum reflector 16 to increase the reflectance of the ultraviolet light emitted from the ultraviolet lamp 13 to increase the utilization of the ultraviolet light.

According to the above configuration, when water to be sterilized passes through the quartz tube 12, ultraviolet rays generated from the ultraviolet lamp 13 are irradiated to decompose microorganisms and organic substances in the water. In addition, at this time, the air introduced into the air inlet through the dehumidifier 17 converts oxygen in the air into ozone by ultraviolet rays generated by the ultraviolet lamp 13.
