Abstract
A process for deodorizing polluted air, wherein the air to be deodorized is washed in a washing apparatus with an aqueous solution of hydrogen peroxide. The solution is circulated in a closed circuit while ozone is introduced either directly into the air to be treated or directly into the aqueous solution which is thus regenerated. The initial weight percentage of hydrogen peroxide in the aqueous solution is within the range of 0.5% to 10%.
