Photochemical systems are an alternative to reduce the biological and chemical contaminants persistent in hospital wastewater treatment. Although the photochemical systems are currently used in wastewater treatments, the efficiency of these systems still needs to be studied. In this work, a broadband method to evaluate the efficiency of photochemical systems: UV/H₂O₂, UV/O₃, and UV/H₂O₂/O₃, for hospital wastewater treatments is presented. The method is based on the analysis of the broadband changes in the UV-Vis absorption spectra with the real-time radiation exposure. The results presented indicate that the UV/H₂O₂/O₃ system has a higher percentage of decontaminated water and decontamination speed than the UV/H₂O₂ and UV/O₃ systems. In this regard, the proposed method provides a good alternative to evaluate the efficiency of photochemical systems used in hospital wastewater treatments.

医院废水处理光化学系统的宽带表征方法

光化学系统是减少医院废水处理过程中持久存在的生物和化学污染物的替代方法。尽管光化学系统当前用于废水处理中，但仍需要研究这些系统的效率。在这项工作中，提出了一种宽带方法来评估光化学系统的效率：UV / H ₂ O ₂，UV / O ₃和UV / H ₂ O ₂ / O ₃，用于医院废水处理。该方法基于对具有实时辐射暴露的UV-Vis吸收光谱中宽带变化的分析。给出的结果表明，UV / H ₂ O ₂ / O ₃该系统具有比UV / H ₂ O ₂和UV / O ₃系统更高的去污水百分比和去污速度。在这方面，提出的方法为评估医院废水处理中使用的光化学系统的效率提供了一个很好的选择。
