Low-temperature plasma has exhibited high efficiency for fast remediation of organic-polluted soil with water content(less than 20%).In the present study,the feasibility of remediation of p-Nitrophenol(PNP)contaminated over-wet soil(water content of 100%)was studied using pulsed corona discharge plasma,which was generated in a needle-plate discharge reactor.Effect of energy input model,including pulse voltage and pulse frequency on PNP degradation,was studied.
