Abstract

The present invention relates to a reactor for the photocatalytic treatment of liquid or gaseous streams, which reactor comprises a tube through which the stream to be treated flows, wherein, in the tube, there are arranged at least one light source, at least one flat means M1 provided with at least one photocatalytically active material and at least one flat means M2 reflecting the light radiation radiated by the at least one light source, wherein the reflecting surface of the at least one means M2 and the inner wall of the tube are at an angle greater than or equal to 0°, in such a manner that the light exiting from the light source is reflected by the at least one means M2 onto the photocatalytically active material, and to a method for the photocatalytic treatment of liquid or gaseous streams by irradiation with light in the reactor according to the invention.
