ABSTRACT
The electrochemical oxidation of the residual ammonia nitrogen contained in biologically pretreated coking wastewater using three-dimensional electrode system was studied. The results show the Ti/RuO2/IrO2 anode plates and the coke have good surface characteristics for the purpose of this study. In addition, studies also show that the three-dimensional electrode system should be able to give a satisfied solution to the residual bio-refractory ammonia nitrogen in biologically pretreated coking wastewater in comparison to conventional two-dimensional electrodes. At coke size of 10-20 mesh, electrode distance of 1.0 cm and current density of 4.5 mA/cm2, the residual ammonia nitrogen in the three-dimensional electrode system was almost completely removed in 60 min.
