The integrated removal technology of SO₂, NO_x and CO₂ is an emerging low-cost flue gas purification technology, in which the oxidation of NO is the key to this technology. In view of the fact that the UV-enhanced NO oxidation by H₂O₂ has the advantages of simple process, good maneuverability and easy enlargement, a pilot system was established to explore the apparent kinetics of NO Oxidation. The influences of NO concentration in flue gas, dosage of H₂O₂, UV radiation intensity and temperature on the reaction were investigated sequentially. After regressing corresponding parameters based on experimental data, an apparent kinetic model to describe the NO oxidation by H₂O₂ enhanced by UV irradiation is obtained, which provides a reference for further design on a larger-scale plant.

SO ₂，NO _x和CO ₂的综合去除技术是一种新兴的低成本烟气净化技术，其中NO的氧化是该技术的关键。鉴于H ₂ O ₂对UV增强NO的氧化具有工艺简单，可操作性好和易于扩大的优点，因此建立了一个中试系统以探索NO氧化的表观动力学。烟气中NO浓度，H ₂ O ₂用量的影响，依次研究了UV辐射强度和反应温度。根据实验数据对相应参数进行回归后，得到一个表观动力学模型，描述了紫外线辐射增强的H ₂ O _2引起的NO氧化，为进一步设计大型装置提供了参考。
