The landfill leachate is a highly contaminated matrix containing large amounts of organic and inorganic substances that require effective treatment methods.This study was aimed to evaluate the efficiency of electrokinetic-assisted phytoremediation (EAPR) to treat the solid waste leachate in a hydroponic system (with Cyperus alternifoliusplant). According to the results, the removal efficiency of biochemical oxygen demand (BOD5), chemical oxygen demand (COD), total Kjeldahl nitrogen (TKN),total suspended solids (TDS), total dissolved solids (TSS), total organic carbon (TOC), chlorides, and ∑metal were 34.92 mg/L,35.21 mg/L, 42.53 mg/L, 42.68 mg/L, 46.87 mg/L, 46.92 mg/L, 44.12 mg/L, and 23.41 mg/L, respectively in sole phytoremediation process, 38.83 mg/L, 43.71, 43.72 mg/L, 45.42 mg/L, 53.78 mg/L, 47.71 mg/L, 45.74 mg/L, and 24.32 mg/L, respectively in sole electro-kinetic process, and 60.18 mg/L, 63.53 mg/L, 67.42 mg/L, 68.72 mg/L, 75.46 mg/L, 72.26 mg/L, 69.96 mg/L, and 41.39 mg/L, respectively in EAPR process. Based on the results, we can concludethe EAPR process is an efficient option for the elimination of contaminants and hazards from the landfill leachate. [ABSTRACT FROM AUTHOR] |
