Abstract

A water purifying device and method for purifying water by efficiently decomposing unwanted organic substances present in water. The water purifying device comprises a water flowing tank through which water to be purified is made to flow in one direction, one or more platy nonwoven fabrics permeable to water, placed in the water flowing tank, and composed of fibers having a photocatalytic function, and an ultraviolet radiation irradiating means for irradiating the platy nonwoven fabrics with ultraviolet radiation. The device is characterized in that the ultraviolet irradiating means has a shape extending in the length direction and can radiates ultraviolet radiation having peak wavelengths in the range from 180 to 190 nm and in the range from 250 to 260 nm, and the platy nonwoven fabrics are parallel to the length direction of the ultraviolet irradiating means.
