| Abstract: | This paper deals with the experiments for evaluation of electro catalysis technology as an advanced treatment of the effluent of a SBR system for treating landfill leachate. The operational optimum condition for electro catalysis was determined by orthogonal tests, i.e., pH is 8.0; anode material: RuO\-2 IrO\-2 TiO\-2/Ti; current density: 10A/dm\+2; electrode gap: 0.5cm; \: 10,000mg/L; SA/L: 50cm\+2/L. Under this condition, COD removal of 82.6% was obtained with the effluent being treated for 48min. It was showed that the current efficiency of COD oxidation reaction reached 31.6%, power consumption 32.4kWh/m\+3. |
