In this studies the influence of the dose and ratio of chemical reagents (Fe²⁺ and H₂O₂) on the efficiency of COD removal and changes of BOD₅/COD ratio in landfill leachate was analysed. The molar Fe2+/H₂O₂ ratio was lower than 1 and amounted to: 1:10, 1:5, 1:3, three research series with 1; 2.5 and 5 g/L Fe²⁺ concentration. A higher efficiency in removing BOD than COD, and therefore the decrease of BOD₅/COD ratio in effluent was stated. The efficiency of COD removal from leachate was from 58.34% (Fe²⁺ 0.5 g/L, Fe2²⁺/H₂O₂ 1:5) to 8.33% (Fe²⁺ = 0.1 g/L, Fe2+/H₂O₂ = 1:10), while the efficiency of BOD removal ranged from 62 to 77%. With the molar ratio Fe²⁺/H₂O₂ equal 1:5 the BOD₅/COD ratio was the largest for each of the analysed Fe²⁺ doses. The lowest BOD₅/COD ratio was observed for the Fe²⁺ dose 0.1 g/L and molar ratio of reagents 1:3.
