Remoção de antibióticos em Wetlands Construídos: uma revisão

Abstract

This work aimed to carry out a survey of data from the existing literature regarding the removal of antibiotics in Constructed Wetlands (WC), to know and evaluate the efficiency of the configurations used, and to conclude which are the best options according to each antibiotic class. To meet this objective, a selection of works was carried out on the platforms Science Direct ©, Web of Science ©, Scopus © and Google academic, after reading the titles, keywords and abstract, 71 articles were selected for full reading, after At this stage, 31 works were definitively selected, among these, two are dissertations from Brazilian graduate programs. Data on antibiotics removed, scale, vegetation, sediment, flow, water retention time (HRT) and hydraulic head were extracted from these studies. Altogether 44 antibiotics had removal rates indicated, these belonged to 11 classes, observing the best removal rates, these values were compared with the configurations that provided them, and it is concluded, therefore, that the real scale obtains better rates, just as all flows ensured removal of antibiotics above 90%, the vegetation that ensured most of these removals successfully was Cyperus altenifolius L., as for sediments, the ones that showed better performance were shells and oysters, zeolites, healing stone and ceramics . However, it is still necessary to remember that each antibiotic has a different structure, even within a class, some obtain satisfactory results and others not in the same configuration. It was shown that this system is a viable alternative, which satisfactorily complements the conventional methods of effluent treatment.
