A flat plate serpentine reactor modified from ultraviolet disinfection pool in municipal wastewater treatment plants was developed for the removal of 17-ethinylestradiol (EE2) for the first time. The photocatalytic degradation performance of EE2 was investigated in this serpentine reactor under different conditions such as inlet concentrations, loaded catalyst concentrations, incident radiations fluxes, and flow velocities. More than 98% of EE2 was removed under certain conditions within 120 min. An integrated model including a six-flux adsorption-scattering model and a modified flow diffusion model was established to investigate the effect of radiation field and flow velocities, respectively. A satisfactory agreement was observed between the model simulation and experimental results, showing a potential for design and scale-up of photocatalytic reactor for wastewater treatment.
首次开发了一种从市政污水处理厂紫外线消毒池中改进的平板蛇形反应器,用于去除 17-乙炔基雌二醇(EE2)。在该蛇形反应器中,在不同条件下(如入口浓度、负载催化剂浓度、入射辐射通量和流速)研究了 EE2 的光催化降解性能。在某些条件下,120 分钟内可去除超过 98%的 EE2。建立了一个集成模型,包括六通量吸附-散射模型和改进的流动扩散模型,分别研究辐射场和流速的影响。模型模拟与实验结果之间观察到良好的一致性,表明该光催化反应器具有用于废水处理的设计和放大的潜力。
