Study on the Treatment of Refractory Organic Waste Liquid by Supercritical Water Oxidation Technology
摘要: 超临界水氧化技术具有净化效率高、反应速率快、有机物降解彻底、无二次污染等优点，常用于高浓度难降解有机废液无害化处理中。本文比较了超临界水氧化法、焚烧法、Fenton试剂法、湿式空气氧化法处理有机废液的特点及其处理不同浓度、不同热值有机废液的应用条件，介绍了超临界水氧化降解火炸药废液、推进剂废液、放射性废液等的反应机理、工艺运行参数及其主要元素降解路径，为超临界水氧化处理难降解有机废液大规模工程应用奠定了基础。
Abstract: Supercritical water oxidation (SCWO) technology has the advantages of high efficiency, fast reaction rate, complete degradation of organic and no secondary pollution. It is often used in the harmless treatment of high-concentration refractory organic waste liquid. This paper compares the characteristics of SCWO, incineration method, Fenton reagent method and wet air oxidation in the treatment of organic waste liquid and its application conditions for the different concentrations and calorific values of organic waste liquid. The reaction mechanism, process operation parameters and degradation paths of the main elements of SCWO treatment explosive waste liquid, propellant waste liquid, and radioactive waste liquid are introduced, which lays a foundation for SCWO large-scale engineering application.
