Tratamento de efluente gerado na síntese de resinas fenólicas por meio da combinação do processo Fenton e biorremediação com o fungo Calvatia gigantea

Abstract

This work applies the Fenton advanced oxidative process (AOP) together with the bioremediation activity (biological treatment) of the fungus Calvatia gigantea to treat an industrial effluent made from phenolic resins. The improper disposal of this type of waste causes severe environmental problems due to its high toxicity. The results showed a 92.02% reduction in total phenols and an 85.44% reduction in COD (Chemical Oxygen Demand) using the combination of these two types of treatment. At the end of the stage, although these two parameters did not meet the limits required by the environmental legislation CONAMA 430/2011 and CEMA 70/2009, the combined use of the Fenton process and bioremediation managed to fulfill the proposal. Therefore, in order to be more effective, it is necessary to choose a more efficient AOP and a longer biological treatment time.
