Strong oxidizing active species

shock wave and ultraviolet-light in liquid phase high voltage pulse discharge can be effectively applied to the water treatment.Choosing platymonas subcordiformis as the treatment target

we usednozzles-plate water treatment device and gas-liquid hybrid nanosecond pulse discharge to analyze the electric characteristics of reactor and the effects of discharge parameters on inactivation rate of platymonas subcordiformis. The results showed that

the single pulse energy increased with the pulse peak voltage

and the energy efficiency first increased and then reduced and the inflection point appeared when the pulse peak voltage being-7.6 k V with the energy efficiencybeing 34.1%.The inactivation rate of platymonas subcordiformis increased with the pulse peak voltage

pulse frequency and the discharge duration time. When the ventilation gas rate increased

the inactivation rate of platymonas subcordiformis first increased and then reduced. The inactivation rate of platymonas subcordiformis could reach 100% with the pulse peak voltage

the ventilation gas rate

the circulation rate

the discharge duration time and the pulse repetition frequency being-9.4 k V

70 m L/min

380 m L/min

30 min and 70 Hz

respectively.
