Industrial wastewater may contain various organic pollutants that cannot always be effectively removed by conventional wastewater treatment processes. Therefore, increasing attention is being given to advanced oxidation processes, which enable the degradation of persistent organic compounds and their subsequent mineralization.
The aim of this thesis was to evaluate whether the advanced technology of photo-induced oxidation, using hydrogen peroxide and ultraviolet light, is suitable for removing organic pollutants from industrial wastewater. Experiments were conducted in a batch reactor, with set interval (0, 2, 10, 15, 30 min) sampling of the liquid phase and recording of the liquid’s temperature and pH. The identification and quantification of specific compounds were performed using gas chromatography coupled with mass spectrometry, and the total conversion of organic compounds was determined through total organic carbon analysis. The results showed that ultraviolet (UV) light is necessary for the process to be effective, as the efficiency was 93,1% when using a 55 W lamp; in the case of a 10 W lamp, the efficiency was 55,3%, and without UV light, the process did not proceed.
