| Summary: | 3 32 2The 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, endocrine substances, odorous substances, and dyestuffs, 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/mand 15 g/m; and b) UV rays are radiated in a wavelength range of between 200 nm and 300 nm and in a dose of between 50 J/mand 2,000 J/m. |
