RESUMO:

The search for better pollutant disposal techniques has proven to be an important aspect in the environmental field of Chemical Engineering. Organic matter, a preponderant component of sewage produced by houses, presents characteristics that are harmful to water bodies and requires efficient treatment for its removal. As an alternative to traditional methodologies, this work proposes the use of Advanced Oxidative Processes (AOPs) to promote the degradation of compounds, releasing simple substances such as carbon dioxide and water in the form of products, that is, less toxic residues. Such AOPs occur through the action of heterogeneous catalysts, such as transition metal oxides. In an initial stage, it is desired to study the kinetics of the organic matter decomposition reaction against different catalytic solids. For this, a solution of synthetic sewage, composed by BHI broth and other substances, will be used, simulating the natural conditions of a domestic effluent. This study will involve a batch system with constant mechanical agitation, in addition to testing different initial concentrations and pH values, to find an optimal operating range. At regular intervals, aliquots are collected, which will be separated by phase and analyzed by a parameter used as an indicator of the presence of organic compounds. With the results obtained, it is intended to model and construct a reactor in a ramp format, consisting of a solution storage tank, circulation system and the reaction structure containing the catalyst fixed to the surface of the slope. Under the same operating regime and using the catalysts with the best performance in the kinetic study, the performance of the reactor and the conversion generated by it will be evaluated. It is believed that the work is feasible, since the system used in kinetic tests is already in operation, and success in the construction of the reactor is the defining stage of the project.
