Resumo

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.
