摘　　要：介绍了处理高浓度、难降解、小流量有机废水的超临界水氧化中试装置 ,以及利用本装置对不同种类的高浓度有机废水进行了处理 ,处理流量为 90 0～ 10 0 0L/d。当氧化反应时间 >2min时 ,化学耗氧量 (COD)去除率为 98% ;当氧化反应时间 >4min时 ,COD去除率为 99%。This paper discusses the treatment of high concentration, low biodegradability and small flow rate organic wastewater via a pilot-plant-scale experimental set by using supercritical water oxidation. The treatment flow rate is 900～1000?L/d. Through it, different kinds of high concentration organic wastewater had been tested: when oxidation reaction time is more than 2 minutes, chemical oxygen demand (COD) removal rate can achieve 98%, and when reaction time is more than 4 minutes, then COD removal rate can reach 99%. Effluent water quality can meet the national wastewater-discharging standard.
