Integración de procesos biológicos y CWPO asistidos con catalizadores magnéticos para la eliminación eficiente de compuestos farmacéuticos presentes en aguas residuales

Résumé

The present PhD Thesis entitled "Integration of biological processes and CWPO assisted with magnetic catalysts for the efficient removal of pharmaceutical compounds present in wastewater" aimed to evaluate, at laboratory scale, the effectiveness of biological processes and CWPO (Catalytic Wet Peroxide Oxidation) for the removal of pharmaceutical pollutants that are usually present in environmental matrices. This PhD Thesis could be carried out thanks to two research projects: “Red Madrileña de Tratamientos para la Reutilización de Aguas Residuales y Valorización de Fangos” (S2018/EMT) y PLASTICTO-FUEL-MAT - Upcycling waste plastics into Fuel and Carbon Nanomaterials (POCI-01-0145-FEDER-031439). According to the numerous scientific references consulted, naproxen, ibuprofen and diclofenac are the most detected non-steroidal anti-inflammatory drugs in various environmental matrices worldwide and represent a potential threat to aquatic ecosystems. Their concentrations in surface waters often exceed predicted no-effect concentrations. This means that these drugs can have acute, chronic, and lethal effects on the life of organisms in these environments. In this sense, our objective is to evaluate the effectiveness of the CWPO method (6 studies in total) and the method of integration of the activated sludge process and CWPO (only one study) for the removal of pharmaceutical contaminants...
