Removal and speciation of heavy metals in the constructed wetland treating landfill leachate

Abstrakt

The results of heavy metals removal and speciation of metals at two treatment wetlands receiving landfill are discussed. The first TW is a surface flow facility consisting of 10 ponds. The next TW is a newly constructed pilot-scale facility consisting of three beds with alternately vertical and horizontal sub-surface flow. The metals concentrations were analysed in leachate(both TWs) and bottom sediments (surface flow TW). Seasonal retention and release ofdifferent metals was discussed. Very high (90.9 - 99.9%) removal effectiveness of metals was observed in case of a mature surface flow TW. The effectiveness of metal removal in a newly constructed sub-surface flow wetland were considerably lower (from 0 to 73%). A study of metal distribution in aqueous - solid phase and metal speciation into labile and stable fractions may contribute to better understanding of metal removal in a TW for LL treatment.
