| Abstract | Investigations were performed on tannery wastewater, previously coagulated with FeCl(3). An electrolyzer was equipped with two graphite cathodes and Ti/SnO(2)/PdO(2)/RuO(2) anode, divided by the diaphragm made of asbestos fibre. The current density was: cathodic 2.0 A/dm(2) and anodic 2.1 A/dm(2). After 55 min of the process the catholyte was transferred into the anodic space and the process was continued. After 55 min of electro-Fenton process, the COD was reduced by 52.0% (current efficiency of COD removal was 10.6%). Electrooxidation continued by the anodic process resulted in elimination of ammonia in 55 min and a total reduction of COD by 72.9%. The coupled process d could be considered a simulation of the combined process under flow conditions. The effect of this process was compared to that of a two-steps process: Fenton process followed by indirect anodic oxidation. |
