Hybrid electric discharge plasma technologies for water decontamination:a short review

摘要

Electric discharge plasma(EDP)can efficiently degrade aqueous pollutants by its in situ gen erated strong oxidative species(OH,0,H2O2.O.etc)“nd other physiochemical effects(UV irradiation,shockwaves,local high temperature,etc),but a high energy consumptions limit the application of EDP in water treatment.Some adsorbents,catalysts,and oxida nts have been employed for en hanci ng the degradation of pollutants by discharge plasma.These hybrid plasma technologies offer improved water treatment performance compared to dischai'ge plasma alone.This paper reviews the water decontamination performance and mechanisms of these hybrid plasma technologies,and some suggestions on future water treatment technologies based on discharge plasma are also proposed.
