摘　　要：研究了用超临界水氧化法（ＳＣＷＯ法）在６７３．２～７７３．２Ｋ、２４～３０ＭＰａ条件下处理含硫废水。结果表明，ＳＣＷＯ可将硫离子高效去除。增加反应空时、压力、氧硫比可显著提高硫的去除率。较低温度下，温度的升高对硫的去除率影响不明显；较高温度下，升高温度可显著提高硫的去除率。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 temperature range.
