Abstract
Landfill leachate is a complex wastewater matrix characterized by high organic load, low biodegradability, elevated salinity, and the presence of inorganic contaminants. This study comprises two complementary but experimentally independent blocks: reagent-assisted Fenton coagulation treatment of real mature landfill leachate and electrochemical investigation of an Fe78.5Ni1.0Mo0.5Si6.0B14.0 metallic glass in the same leachate matrix. Among three reagent-treatment configurations, preliminary aeration followed by Fenton oxidation and subsequent coagulation was the most effective, reducing chemical oxygen demand (COD) from 3218 ± 24 to 1091 ± 34 mg L−1 (66.1%) and NH4+–N from 555.7 ± 8.6 to 225.3 ± 6.4 mg L−1 (59.4%). However, this configuration also produced the highest air-dried solid residue yield (2533 ± 104 mg L−1). XRF analysis identified Zn, Pb, Cr, Ni, and Cu in the separated solid fractions. Increasing the H2O2 working-solution concentration above 0.5 wt.% resulted in only minor changes in COD. In the independent electrochemical experiments, H2O2 strongly modified the electrochemical response of the Fe-rich metallic-glass surface, while polarization induced pronounced potential-dependent interfacial reconstruction. SEM/EDS revealed localized accumulation of Cd, Hg, and Cu on the electrochemically modified surface. These observations provide the experimental basis for the proposed Dynamic Multifunctional Reactive Interface (DMRI) concept, which couples Fe transformation, H2O2 interaction, surface reconstruction, and localized contaminant accumulation at an evolving solid–liquid interface. Fe2+/•OH formation and quantitative bulk-metal removal were not directly measured. The results identify a future process-development route in which a recoverable metallic-glass electrochemical stage could precede Fenton coagulation treatment.
