2-naphthol

as a harmful pollutant

has seriously affected on human health.It is difficult to completely decompose 2-naphthol by traditional wastewater treatments.Supercritical water oxidation（SCWO） is the promising technology for the treatment of organic-contained wastewater.The supercritical water oxidation of 2-naphthol was investigated

and the effects of temperature

pressure and residence time on the decomposition of 2-naphthol were investigated

the results show that the removal rate of 2-naphthol was increased with the raising of the three factors.Degradation of Cu2+ and Mn2+ on the 2-naphthol was compared

and Cu2+ had a better catalytic efficiency.Under these conditions

appropriate conditions in this experimental system were determined.
