Removal of Refractory Pollutants from Landfill Leachate Using Two‐Phase System

Abstract: The study focused on the problem of removing refractory substances from leachate treated by means of activated sludge method and advanced oxidation process. Biological treatment was conducted in sequencing batch biofilm reactor. Biologically treated leachate was subject to further chemical treatment with the use of Fenton reagent. The permanent dosage of H2O2 amounting to 2 mg x L(-1) was applied. Fe(II):H2O2 ratio was 1:10, 1:5 and 1:3. Biological treatment allowed for removing 97% of benzene and only 20% of … Show more

“…For a young leachate, the organic components are much higher as compared to old or matured one. Successful reduction of leachate contaminants can be done using stripping accompanied by flocculation, MBR, and RO therapy [26]. A combination of MBR and electro-oxidation methods can reduce COD and NH + 4 -N and were followed by substantial detoxification [32].…”

“…Hydroxyl radicals efficiently mineralise or convert indecomposable organic compounds to biodegradable forms, which are then removed in biological processes. During reactions between substances dissolved in landfill leachate and Fenton's reagent, compounds with high molecular mass are converted into compounds with low mass, and complex aromatic and aliphatic hydrophobic chains are transformed to substances with the hydrophilic structure [Zhao et al 2013, Koc-Jurczyk 2014. The effectiveness of the process depends on the pH, doses and molar ratio of reactants (Fe 2+ and H 2 O 2 ) and ratios H 2 O 2 /COD as well as Fe 2+ /COD.…”
