This study deals with the photochemical degradation of the model compound tetracycline, an aqueous pollutant derived from the degradation of the bactericide oxytetracycline (OTC), in the innovative photoreactor FluHelik, designed to promote pollutant abatement in liquid phase through HO/UVC and UVC processes. Computational fluid dynamics (CFD) simulations were performed to predict the behavior of the photoreactor in the laboratory scale. The simulations revealed a well-defined helicoidal flow pattern around the UVC lamp in the photoreactor, and the effect of different operational conditions (e.g., flow rate and light intensity) on the reactor's performance was evaluated, allowing to optimize the equipment.
本研究涉及模型化合物四环素的光化学降解，四环素是由杀菌剂土霉素（OTC）降解产生的一种水污染物，在创新型光反应器 FluHelik 中进行处理，该光反应器旨在通过 HO/UVC 和 UVC 工艺促进液相中污染物的去除。进行了计算流体动力学 (CFD) 模拟，以预测实验室规模下光反应器的行为。模拟结果表明，在光反应器中，UVC 灯周围形成了一种明确的螺旋流模式，评估了不同操作条件（例如流速和光强度）对反应器性能的影响，从而实现了设备的优化。
