| Outline of Final Research Achievements |
The hybrid processes of hydrothermal oxidation and Fenton, UV or cavitation process have been developed to allow for advanced treatment of wastewater containing persistent pollutants under mild reaction condition. Cu/Ni binary catalyst was found to enhance the decomposition of pollutants because of acceleration of Fenton-like reaction by inter-element interaction. A hybrid process of hydrothermal oxidation and UV showed no appreciable superiority with respect to hydrothermal oxidation alone. Hydrodynamic cavitation could be successfully generated under hydrothermal condition using a Venturi tube, which promoted the decomposition of pollutant by hydrothermal oxidation.
