Abstract
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.
