More Information
Summary:The invention relates to a method for treating water, especially waste water and drinking water, containing both pathogenic germs and a substance which is difficult to decompose and is from the group comprising persistent substances, endocrinal substances, odorous substances, and dyes, by means of ozone supply and UV radiation. The inventive method comprises the following steps: a) ozone is supplied in a concentration of between 0.1 g/m3 and 15 g/m3; and b) UV rays are radiated in a wavelength range of between 200nm and 300nm and in a dose of between 50 J/m2 and 2,000 J/m2. L'invention concerne un procédé de traitement des eaux, en particulier des eaux usées ou de l'eau potable, par introduction d'ozone et irradiation aux ultraviolets, les eaux à traiter contenant à la fois des germes pathogènes et au moins une substance difficilement dégradable appartenant au groupe comprenant les substances rémanentes, les substances endocrines, les substances odorantes et les substances colorantes. Ce procédé consiste à introduire de l'ozone dans une concentration comprise entre 0,1 g/m et 15 g/m et à procéder à une irradiation aux ultraviolets dans une longueur d'onde située entre 200 nm et 300 nm et une dose comprise entre 50 J/m et 2000 J/m .
