摘要
渗滤液的 SBR出水中 COD、NH3-N的去除实验研究表明 ,在一定条件下 ,电解 10 0 0 m L渗滤液的 SBR出水 ,3 0 min时 ,NH3-N几乎全部去除 ,2 h时 ,COD的去除率达 93 .5 % ;COD、NH3-N的去除反应符合一级反应 ,其速率常数随电流密度的增大、电极间距的减小而增大。
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.
