It consists of a limited resource, increasingly scarce in some regions of the world. Contamination of surface and underground water sources by organic chemical compounds is definitely a matter of concern. Lately, there are many alternatives used in the treatment of wastewater and drinking water, among them, the advanced oxidative processes have gained great acceptance for the disinfection and decontamination of effluents. Treatments by advanced oxidative processes have good efficacy in eliminating chemical and microbial contaminants in water. The main highlight of advanced oxidative processes is the in situ production of the highly reactive species of the hydroxyl radical (•OH), the superoxide radical (•O2-) and the sulfate radical (•SO4-), which can fragment organic pollutants and pathogens. These processes are based on electrogeneration of hydroxylic radicals (•OH), which can react non-selectively with organic pollutants until their complete removal. Radicals (•OH) have a high redox potential (2.8 eV/SHE), being able to attack organic compounds in four ways: hydrogen abstraction, combination, addition of radicals and electron transfer. This study presents the construction of a pre-pilot scale electrochemical reactor for the electrochemical treatment of anodic oxidation in wastewater from the petroleum industry, textile, pharmaceutical and pesticide industries, disinfection of water with potability potential as an alternative replacement for chlorine a so that it can be a remediation alternative with low cost of assembly, installation and energy consumption, using solar energy sources. The results of this research reveal that electrochemical oxidation, used on a pilot plant scale, is efficient and can be used in conjunction with other wastewater treatment techniques. It can also be an alternative for disinfecting water with potability potential, without the use and storage of chlorine. The reactor proved to be efficient, with the possibility of being applied anode electrodes of different materials according to the economic viability of the material, being able to be used for different types of effluents, thus contributing to other researches and, consequently, increasing the variety of effluent to be treated by the same equipment.Acesso EmbargadoTratamento eletroquímicoÁguas residuáriasPlanta pilotoDesinfecçãodoctoralThesis
