Introduction to Ozone Catalytic Oxidation Technology and Its Application in Wastewater Treatment

摘要: 本文的重点是对常规水处理技术难以处理的有机物进行催化臭氧化。实验旨在利用臭氧降解产生的活性自由基，对水中有机物进行分析。与均相催化臭氧化技术相比，多相催化臭氧化技术具有易于回收、水处理成本较低、活性较高、提高有机物矿化率等优点。本文对臭氧催化氧化剂技术进行概论，明确臭氧催化氧化处理水中有机物的关键影响因素，并选用工业废水作为水源，利用SEM对催化剂活性进行识别和分析，从相互作用与自身组分等多方面来验证自制催化剂性能与结构稳定性，为臭氧催化氧化处理水中有机物提供参考。

Abstract: The focus of this paper is the catalytic ozonation of organics that are refractory to conventional water treatment techniques. The experiment aims to use the active free radicals produced by ozone degradation to analyze organic matter in water. Compared with homogeneous catalytic ozonation technology, heterogeneous catalytic ozonation technology has the advantages of easy recovery, lower cost of water treatment, higher activity, and improved mineralization rate of organic matter. This article gives an overview of ozone catalytic oxidant technology, clarifies the key influencing factors of ozone catalytic oxidation treatment of organic matter in water, and selects industrial wastewater as the water source, uses SEM to identify and analyze the catalyst activity, and verifies it from the aspects of interaction and its own components. The performance and structural stability of the self-made catalyst provide a reference for the ozone catalytic oxidation treatment of organic matter in water.
