Electric coagulation method and treatment of the experimental study of landfill leachate

摘要

Garbage leachate high concentrations of organic matter is considered difficult to deal with wastewater. The complex and changeable water quality makes traditional processing method difficult to achieve better treatment effect. So the electric coagulation method processing technology application becomes inevitable trend. Using Fe as the anode and C as the cathode to treat leachate of a certain garbage in electric coagulation depth processing, and explore the electrolysis time, initial PH value, plate spacing and current density effect of the treatment effect. Results show that when the initial PH value was 6, plate spacing was 3 cm and current density was 9ma/cm~2, electrolysis 60 min reached optimal effect, the COD removal rate was 84.5% and the TSS removal rate was 69.2%.
