Abstract: The object of the present invention is a method for the photocatalytic treatment of aqueous mixtures of polluting substances. Such a method consists in submitting such mixtures to irradiation in the presence of titanium dioxide while they are circulating inside a reactor formed by a hollow space of not more than 5 cm of thickness, whose inner wall is the wall of a lamp emitting at least a fraction of its radiations with a wavelength shorter than 400 nm.In this reactor a cooling sheath is not provided between the lamp and the reaction mixture and temperature control is accomplished by means of the circulation of the same reaction mixture inside the reactor.
Abstract translation: 本发明的目的是用于光催化处理污染物质的含水混合物的方法。 这种方法包括将这样的混合物在二氧化钛存在下进行照射，同时在由不大于5cm厚的中空空间形成的反应器内循环，其中的内壁是发射至少一个 其辐射的分数波长小于400nm。 在该反应器中，在灯和反应混合物之间不设置冷却护套，并通过在反应器内部循环相同的反应混合物来实现温度控制。

Abstract: A method for purifying water containing pollutant mixtures is described, which uses a reactor containing a semiconductor as reaction catalyst and a lamp which emits radiation having a wavelength of less than 400 nm. The reactor, characterized in that its walls allow water and the pollutant substances to pass through, is immersed in the water to be purified so that the pollutants contained in it reach the reactor interior where they are adsorbed on the semiconductor activated by light radiation, and are then degraded.
