Effectiveness of Removal of Humic Substances and Heavy Metals from Landfill Leachates During their Pretreatment Process in the SBR Reactor

In the paper the removal efficiency of heavy metals as well as humic compounds, in the treatment of leachate mixed with municipal waste in a sequencing batch reactor was studied. Also, the accumulation of those metals in the activated sludge was examined. It has been shown that the removal efficiency of contamination with humic compounds, for Bx ranging from 0.23 to 0.45 mg COD mg-1 d.m. can reach 71÷74%. An increase in the concentrations of heavy metals in the activated sludge was recorded for Bx in the range 0.23÷1.64 mg COD mg-1 d.m. The amount of heavy metals in the effluent of the SBR in carrying out the process at Bx = 0.23÷0.96 mg COD mg-1 d.m. does not limit their discharge into water and sewer system.
