摘　　要：简单介绍了超临界水氧化处理高浓度印染废水及污泥的技术优势,阐述了一套自主设计的超临界水氧化系统工艺流程和其核心部件反应器的创新设计特点,重点论述了印染有机物超临界水氧化反应条件的确定以及水热燃烧反应器材料的选择,同时估算了该系统的设备投资和运行费用。结果表明,超临界水氧化技术是一种经济可行的高浓度印染废水及污泥处理技术。The advantages in treating high concentration textile wastewater and sludge by supercritical water oxidation are briefly introduced. An originally designed supercritical water oxidation process with the innovational design of the reactor is presented. The determination of supercritical water oxidation conditions for textile pollutants treatment and selection for reactor material are highlighted. The investment and the operational cost of this system are also calculated,respectively. The results show that the supercritical water oxidation technology for treating high concentration textile wastewater and sludge is economically feasible.
