摘要：
The elimination of 81 pharmaceuticals (PhACs) by means of a biological treatment based on the fungus Trametes versicolor was evaluated in this work. PhAC removal studied in different types of wastewaters (urban, reverse osmosis concentrate, hospital, and veterinary hospital wastewaters) were reviewed and compared with conventional activated sludge (CAS) treatment. In addition, hazard indexes were calculated based on the exposure levels and ecotoxicity for each compound and used for the evaluation of the contaminants removal. PhAC elimination achieved with the fungal treatment (mean value 76%) was similar or slightly worse than the elimination achieved in the CAS treatment (85%). However, the fungal reactor was superior in removing more hazardous compounds (antibiotics and psychiatric drugs) than the conventional activated sludge in terms of environmental risk reduction (93% and 53% of reduction respectively). Fungal treatment can thus be considered as a good alternative to conventional treatment technologies for the elimination of PhACs from wastewaters. (C) 2016 Elsevier B.V. All rights reserved.
