Özet
The surge in pharmaceutical use during global pandemics, like SARS-CoV-2, has led to increased antiviral concentrations in wastewater treatment plant influents. The low biodegradability of certain antivirals poses a challenge for wastewater treatment, threatening aquatic and soil ecosystems. This study aimed to optimize ozonation and catalytic ozonation processes for removing two anti-COVID-19 drugs (namely, favipiravir and oseltamivir) and assess their ecotoxicological effects in the context of potential wastewater reuse. In this study, samples with 50 µg/L of favipiravir and oseltamivir were added to synthetic wastewater with approximately 50 mg COD/L, mirroring a typical domestic effluent. Experiments involved three ozone doses (0.2, 0.6, and 1 mg O3/mg DOC) at pH levels of 7 and 10. Adding 0.1 g/L of ZnFe layered double hydroxide as a catalyst aimed to improve the ozonation efficiency. Samples with 0.1 …
