摘要
采用电催化氧化法处理渣场渗滤液废水,考察了极板材质、极板间距、电流密度、反应时间等因素的影响。结果表明,在Ru-Ir-Ti电极、极板间距20 mm、电流密度25 mA/cm^(2)、反应时间60 min条件下处理效果较好,COD去除率71.97%,B/C值由0.028上升到0.52,水质可生化性得到明显提高。
Leachate wastewater from slag yard has been treated by electro-catalytic oxidation.The influences of the factors,such as electrode material,polar plate distance,current density,electrocoagulation time,etc.The results showed that the removal efficiency of COD could be expected to reach 71.97%under the Ru-Ir-Ti,late distance 20 mm,current dinsity is 25 mA/cm^(2),electrolysis time 60 min.The B/C value increased from 0.028 to 0.52,significant improvement in sewage biodegradability.
