Annotation:
The authors of the article note the relevance of solving the problem of wastewater purification from oil products dissolved fractions. It is shown that development of technologies based on advanced oxidation processes is nowadays one of the promising directions. A system of combined effect of polychromatic UV radiation with hydrogen peroxide is considered. A xenon flash lamp was used as a source of continuous spectrum radiation. The initial concentrations of oil products in model solution made 10±2 mg/l, the initial concentration of hydrogen peroxide – from 0 to 200 mg/l. Direct photolysis of the oil products has proven a fairly low rate of the process. However, the addition of hydrogen peroxide to a solution irradiated by polychromatic light drastically enhances the photodecomposition rate. The optimal concentration of hydrogen peroxide providing maximum rate of oil products decomposition was selected.
