废水处理催化超临界水氧化法影响因素及动力学分析

摘要

Affecting factors and kinetics by catalytic supercritical water oxidation were summed up,and the importance of catalyst in the process of catalytic supercritical water oxidation was emphasised. In addition,general kinetic model for catalytic supercritical water oxidation was deduced. Kinetic parameters and reacting conditions of organic compounds including phenol ,acetic acid and pyridine are expounded. The performance of complex compounds by catalytic supercritical water oxidation was discussed based on the above results. All of which offers theoretical guidance for waste water treatment. In the end,some suggestions were proposed for scale-up and engineering utilization of catalytic supercritical water oxidation.%归纳了催化超临界水氧化法的影响因素并分析其相互间的关系，阐明催化剂作用的重要性。此外，论文还推导了反应体系普遍的动力学模型，分别分析了环状化合物、难降解中间产物及含氮化合物的动力学特征参数及反应条件的制约关系，在此基础上讨论复杂有机化合物废水的反应动力学行为，以期为实际废水处理提供理论指导。论文的最后对催化超临界水氧化法的工程开发与实际应用化问题提出了若干构想与建议。
