摘要

This study evaluated the feasibility of E-Fenton oxidation for treating the concentrates generated in nanofiltration of biologically pretreated landfill leachate. H2O2 was in-situ electrogenerated at the XC-72 carbon-polytetrafluorethylene (PTFE) cathode. The effects of initial Fe2+ concentration, current density, pH on TOC, TN, and NH4-N removal were investigated. The optimal operation condition of the E-Fenton treatment was determined to be 10 mM Fe2+, 30 mA/cm, and pH of 3. Under the optimal condition, the removal efficiency of TOC, TN, and NH4-N were 73.8%, 81.9%, and 51.3% after 360 min of E-Fenton treatment. The results indicated that E-Fenton oxidation was effective in removing the recalcitrant organic pollutants in the leachate concentrates.
