Advanced Oxidation Processes Against Phenolic Compounds in Wastewater Treatment

摘要

Experiemental research into the oxidative treatment of aqueous solutions and wastewaters containing phenolic compounds was undertaken. Ozone, supported by short wave UV-irradiation, hydrogen peroxide and titanium dioxide catalyst, was selected as an oxidant in the following combiantions: O_3, O_3/H_2O_2, O_3/UV, O_3/TiO_2, O_3/UV/H_2O_2 and O_3/UV/TiO_2. 5-Methylresorcinol was chosen as a model compound for the experiemtns with synthetic phenolic soltions. Teh results obatined from these experiemtns were compared with the resutls of oxidative pruification of wastewaters producedfrom the thermal treatment of oil shale in Estonia.
