摘　　要：采用超临界水氧化法对高含量印染废水进行试验研究,考察了废水pH、反应温度、反应压力、氧化剂用量等因素对废水COD去除率的影响。结果表明,改变废水的pH对COD去除率有显著的影响,在pH为9.1、反应温度580℃、反应压力27MPa,过氧量200%的条件下,经处理的废水COD为47mg·L-1,去除率达到了99.8%。使用超临界水氧化法能有效地去除印染废水的COD,达到GB8978-96规定的一级排放标准。The Supercritical water oxidation （SCWO） to treat printing and dyeing wastewater was studied. The impact of reaction temperature, pressure, oxygen excess and pH on removal efficiency of COD was investigated. The experimental results showed that Supercritical water oxidation is efficient for the treatment on COD. And pH is the main factor which affect the removal efficiency of COD. With the temperature 580 ℃, pH 9.1 the pressure 27 MPa, the oxygen excess 200%, the removal efficiency of COD is 99.8%.
