Study on Intermittent Electrolytic Oxidation Process for Preliminary Treatment of Landfill Leachate
A intermittent electrolytic trough system was applied for the preliminary treatment of landfill leachate.The influence of voltage,Cl-mass concentration and pH on the removal effect of various indexes of landfill leachate with high mineralization degree was studied.The results showed that electrolytic oxidation process was effective on the treatment of landfill leachate with high mineralization(COD≤2 000 mg·L-1,NH4+-N mass concentration≤2 000 mg·L-1).COD,NH4+-N and chroma could be removed effectively and the biodegradability of leachate was also improved.
