ANÃLISE DA EFICIÊNCIA DE REMOÇÃO DE DQO NO PROCESSO DE ELETROCOAGULAÇÃO VIA ELETRODOS DE ALUMÃNIO APLICADO AO TRATAMENTO DE CHORUME

Abstract

The electrocoagulation is a treatment process that consists of the electrical discharges application in the effluent through a cell has aluminum electrodes (cathodic and anodic metal plates), powered by a direct current source. This process provides the wastewater oxygenation and various dissociation reactions and rupture in more complex organic molecular chains common in waste as leachat. The area and volume required for the deployment of this technology of treatment are reduced compared to conventional biological processes. For the evaluation of electrocoagulation process efficiency, was used an experimental electrolyte device, were measured physical, chemical and biological parameters of leachat samples of Umuarama city landfill – PR – Brazil. Was simulated the batch scheme depending on the variation of electric power parameters of the experimental electrolyte device and and variation in the detention time. Obtained a reduction of about 72% in COD for detention times between 15 and 30 minutes. Index Terms -  Eletro-coagulation, leachat, Treatment, Efficiency.
