Abstract

This project aims at evaluating the possibility of combining an anaerobic biological process with advanced chemical oxidation through the Fenton's reaction for the treatment of vinasse generated in the production of ethanol from sugar cane. It is intended, in particular to add value to the process by increasing methane and energy production. Thus, an anaerobic digestion step will firstly be used to convert the biodegradable organic matter of the vinasse into methane, the effluent from the biological process being then subjected to chemical oxidation by the Fenton's reaction to reduce the toxicity and enhance biodegradability; finally, the effluent from the Fenton's process will be recirculated back to the anaerobic reactor to produce methane, thus making the treatment process economically more viable and reducing the impact on the environment.
