Abstract

The hybrid discharge reactor was designed for the application of wastewater treatment and the removal of hazardous volatile organic substances in water. This discharge type was similar to the barrier discharge, and the surface discharge on the dielectric surface was propagated to the water surface. That caused the heterogeneous chemical reaction strongly at the interface between the working gases and the water surface. Changes of the conductivity, acidity, and the dissolved ozone with respect to the treatment time and water quantities were studied as the fundamental experiment. The concentration of hydrogen ions largely increased with increasing the treatment time and the conductivity increased with respect to the increase of water quantities under the constant other discharge parameters.
