Estudo comparativo da tratabilidade de efluente de laticinio através de processo oxidativo avançado

Abstract

Due the fact of the wastewaters’ high pollutant potential produced by dairy industries and the need of maintenance of water resources, the present dissertation for the grade of Master in Applied Ecology to Management and Conservation of Natural Resources have a main proposal to show alternatives of minimization of organic matter, with the use of Advanced Oxidative Process (AOP) through of the Fenton’s Reactant. Two reaction environments was tested, with total an partial light incidence and two types of add reactants, in two steps and in continuous mode, in sense of reach the best arrangement to the BOD5,20 and COD removals. To knowledgement of the dynamic of removal of BOD5,20 and COD, the concentration of this parameters was followed at each 30min, during 2h. Wastewaters of two different dairy industries in Zona da Mata was used in the experiments. The results guide to the best reaction arrange, that was done in continuous mode with total light incidence, where meaningful BOD5,20 and COD removals happens in the first hour of treatment, making the treated wastewater more susceptible for biological treatment in subsequent levels.
