A Hydrogen Thyratron Pulsed Power Source Applied to Treatment of Phenol Combined with TiO2 Photocatalyst
A hydrogen thyratron pulsed power source is applied to phenol treatment. The pulsed power source have an maximum output voltage of 50 kV, with rise time 200 ns, pulse duration 400 ns, maximum pulse repetition rate 200 pps. The maximum pulse energy is 2.5 J/pulse and an average pulse power is 0.5 kW. With the output voltage of 20 kV, pulse repetition rate of 100 pps and the pulse energy of 2 J/pulse, the phenol degradation efficiency is 76.1% after 60 min degradation with air bubbling. When the TiO2 photocatalyst is applied in the discharge system to form photoelectrocatalysis, the phenol degradation efficiency enhances to 87.3%. The energy utilization efficiency is 4.57686e-11 mol/J.
