| abstract | (57) [Summary] [PROBLEMS] When permeation performance of a membrane is reduced due to adhesion of organic pollutants, organic substances can be decomposed and removed without using chemicals, and the permeation performance of the membrane can be recovered safely and inexpensively. An object of the present invention is to provide an excellent water treatment method capable of performing stable treatment over a long period of time and not discharging waste chemicals, and a water treatment apparatus capable of efficiently performing the method. SOLUTION: The water containing the organic pollutant 6 is filtered by the membrane 2, and the photocatalyst powder 5 which generates an oxidizing power by irradiating light to the membrane whose filtration performance is reduced due to the adhesion of the organic pollutant 6 is removed. The water containing water is passed through and the photocatalyst is attached to the membrane surface, Subsequently, light is applied to decompose and remove contaminants on the membrane surface, and then the photocatalyst is peeled off, and a means for injecting the photocatalyst powder-containing water into the membrane filtration tank 1 and the membrane surface. A water treatment apparatus comprising: a light source 3 for irradiating light; and means for removing a photocatalyst 5 attached to a film surface. |
