摘要: The performance of the electrochemical oxidation process for efficient treatment domestic wastewater loaded with organic matter was studied. firstly evaluated in terms its capability producing an oxidant agent (H2O2) using amorphous carbon (or felt) as cathode, whereas Ti/BDD electrode used anode. Relatively high concentrations H2O2 (0.064 mM) produced after 90 min electrolysis time, at 4.0 A current intensity and cathode. Factorial design central composite methodologies were successively to define optimal operating conditions reach maximum removal chemical oxygen demand (COD) color. Current time found influence COD contribution on color around 59.1 58.8 %, respectively, 23.2 22.9 respectively. applied under 3.0 intensity, during 120 anode, be condition cost/effectiveness. Under these conditions, average rates 78.9 ± 2 85.5 70 % total achieved.
