<p>A UV pretreatment device comprises a UV lamp, an oxidation reactor, a reagent injector, an overflow unit, a heater, and a UV detector. The UV lamp has a cylindrical shape; and includes an inner wall coated with a TiO_2 catalyst on the external side, and filaments arranged on both sides of the inner wall and generating UV rays having a wavelength of 185 nm or 254 nm. The oxidation reactor is formed as one body with the UV lamp; is separated from the inner wall of the UV lamp at an interval of 2 nm or less to form a space for the oxidation reaction; and has a cylindrical shape and an outer wall with the inner side coated with the TiO_2 catalyst, and the external side coated with chrome. The reagent injector is connected to the space for the oxidation reaction through the outer wall to introduce or discharge a reagent. The overflow unit is connected to the space for the oxidation reaction through the outer wall to discharge air. The heater is combined to the external side of the outer wall to control the temperature of the reagent within the oxidation reactor. The UV detector is combined to the external side of the outer wall to measure the UV intensity. The oxidation reaction of the reagent occurs in the space for the oxidation reaction by using UV rays permeated through the inner wall of the UV lamp.</p> |
