Application of a hybrid discharge reactor with D-A mixed control in phenol degradation

The organic compounds such as the phenol, the acetic acid, and so on in wastewater are always decomposed by using a hybird gas-liquid discharge reactor. A Digtal-Analog (D-A) mixed control method is employed in the power control to satisfy the stringent requirements of the degradation process with extra high voltage output. Zero voltage transition (ZVT) soft switching performance is achieved to reduce the switching losses for all the primary power switches. The experiment results indicate that the amount of chemical oxygen demand (COD) is declined clearly and rapidly by the hybird gas-liquid discharge reactor with D/A mixed control solution. The removal of COD is related to the plasma reactor operation parameters.
