1. A process for treating a liquid, which is charged with pollutants that are difficult to break down, by wet oxidation with an ozone-containing gas and UV radiation, comprising the steps of:

  • passing and dissolving an ozone-containing carrier gas, without exposing the gas to UV radiation, into a liquid which is charged with pollutants, isolating undissolved carrier gas from the liquid containing ozone and removing gas bubbles from the ozonated liquid to render the ozonated liquid substantially free of gas bubbles, and thereafter irradiating the liquid containing ozone with UV radiation to achieve simultaneous radical formation and oxidation with radicals in the liquid.
