Artigo:

Antibiotics are considered emerging environmental issues and the presence of its traces in the environment can induce the development of resistant pathogens and promote allergies. Biological treatment is the most widely used method for industrial wastewater treatment, but it has been proved inefficient for the removal of all hazardous constituents of pharmaceutical products. In this context, the aim of this study is to evaluate the potential of aerobic biodegradation of organic matter present in real antibiotics production effluent using the method proposed by Zahn - Wellens. The organic matter degradation was monitored through periodic analysis of total organic carbon (TOC). After 28 days, the reactor achieved more than 80% of TOC removal, characterizing the wastewater as biodegradable, according to the used methodology.
