Study on landfill leachate waste water from slag yard by electro-catalytic oxidation
Leachate wastewater from slag yard has been treated by electro-catalytic oxidation.The influ-ences 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%un-der the Ru-Ir-Ti,late distance 20 mm,current dinsity is 25 mA/cm2,electrolysis time 60 min.The B/C value increased from 0.028 to 0.52,significant improvement in sewage biodegradability.
