Disclosed is a water treatment apparatus capable of preventing formation of a region where ultraviolet light is not irradiated with, on an inner central portion of a water treatment tube, when the water treatment tubes which are separatively disposed with each other are irradiated with ultraviolet light from a non-contact-type ultraviolet lamp. According to the present invention, the water treatment apparatus comprises: a plurality of water treatment tubes communicably connected to a raw water storing tank so as to introduce water therein from the raw water storing tank and separatively disposed in a case having a specific area; and a plurality of ultraviolet light lamps irradiating ultraviolet light to water in the water treatment tube so as to sterilize bacteria contained in the water. The ultraviolet light lamp further comprises: a plurality of non-contact-type ultraviolet light lamps separatively disposed on an exterior of the water treatment tube; and a plurality of contact-type ultraviolet light lamps installed in the water treatment tube. |
