【Abstract】 A study on the dynamics of COD and NH-3-N removal from leachate by electrocatalysis was carried out in consideration of the roles of current density and electrode gap. The results showed that 93.5% of COD removal could be obtained after 2 hours, and NH3-N was almost removed after 30 minutes. The COD and NH3-N removal followed pseudo-first order kinetics, with the rate increasing with current density and decreasing with the electrode gap.更多还原
