RESUMO:

The treatment of organic contaminants present in groundwater and produced water, effluent from the oil industry, is one of the major challenges faced in recent years. Many researchers have been developed to minimize the impacts caused by these pollutants, when in contact with the environment and with human beings. Electrochemical oxidation has been widely studied because it presents a great potential for degradation of organic contaminants, besides versatility, high efficiency and environmental compatibility. In this sense, the objective of this work was to evaluate the degradation of organic contaminants present in both real water produced and in groundwater in the vicinity of a refueling station at Rio Grande do Norte state contaminated by petroleum products. For this purpose, Boron Doped Diamond (BDD) and Titanium Supported Platinum (Ti/Pt) anodes were used in flow and batch systems using different current densities(15, 30 e 60 mAcm-2). In the groundwater treatment, Na2SOwas used as the supporting electrolyte. Analyzes of Chemical Oxygen Demand (COD), pH, Conductivity, UV-Vis, Total Petroleum Hydrocarbons (TPH) and Aromatic Polycyclic Hydrocarbons (APH) were performed. The results showed that the Best removal efficiency was obtained using the DDB electrode with a current density of 60 mAcm-2 in the flow system, because after 30 min of treatment there was a 100% removal of the organic load in the water produced and after 3 h of treatment there was a 99.10% removal of the organic load in the groundwater.
