PURPOSE: Underground water purifying apparatus and method equipped with a sterilizer for microorganisms including norovirus are provided to easily add and omit elements and to simplify the structure of the apparatus. CONSTITUTION: A micro filter unit is in connection with an activated carbon filter unit. A sterilizer includes a main pipe(410), two protecting pipes(420), two cylindrical lamps(430), and two connectors. The main pipe includes a U-shaped pipe part(411), an expanded pipe(415), and an introducing pipe part(412), and a discharging pipe part. The U-shaped pipe part is composed of two parallel linear pipe parts and a curved pipe part. A photo catalytic coating layer(414) is arranged at the inner circumference of the U-shaped pipe part. The protecting pipes are inserted into the linear pipe parts of the U-shaped pipe part. The cylindrical lamps are inserted into the protecting pipes and generate ultraviolet rays. The connectors combine the protecting pipes and the cylindrical lamps with the U-shaped pipe part. |
