The treatment of sulphur containing wastewater has been accomplished using a supercritical water oxidation(SCWO)process at 673.2~773.2 and 24~30MPa.The results show that SCWO can effectively remove sulphur ion;increasing reaction time,pressure and concentration ratio of oxygen to sulphur can greatly increase sulphur removal efficiency;increasing reaction temperature in the lower temperature range has no remarkable influence on suphur removal efficiency,but has remarkable influence in the higher temperatur...
