Abstract

A water treatment apparatus (100) is a water treatment apparatus in which water to be treated is irradiated with ultraviolet rays radiated from LED elements (31). The water treatment apparatus (100) is provided with: a flow passage (10) through which the water to be treated flows; an LED element housing chamber (30) disposed outside of the flow passage (10) with a window part (20) therebetween, the window part (20) being composed of a transparent member; and a plurality of LED elements (31) disposed in the LED element housing chamber (30), wherein the LED element housing chamber (30) has an inlet (34) and an outlet (35) for a dry gas, and the light emitting surfaces of the LED elements (31) are exposed to the space inside the LED element housing chamber (30).

Description

Technical field [0001] The present invention relates to a water treatment device, in particular to a water treatment device that uses ultraviolet light irradiated from an LED (Light Emitting Diode) element to perform ultraviolet treatment on water to be treated. Background technique [0002] Nowadays, disinfection in water treatment generally uses chlorine. However, in recent years, it has been clarified that there is room for improvement in sterilization performance in disinfection treatment using chlorine. Therefore, in order to sufficiently sterilize the water to be treated such as drinking water that is the object of disinfection treatment, a technology using ultraviolet rays has been developed. Here, as an ultraviolet irradiation device for irradiating ultraviolet rays to the water to be treated, an ultraviolet irradiation device equipped with a mercury lamp as a light source is generally used. However, in an ultraviolet irradiation device equipped with a mercury lamp, the...
