چکیده
Mineral trace elements (MTE) constitute an environmental restriction on the recycling of municipal solid waste incineration-bottom ash (MSWI-BA). The study speciation MTE and factors that control their release allows to predict behavior under different conditions and, consequently, suggest actions expand management MSWI-BA.A geochemical modeling led a better understanding MTE. In this study, target were barium, copper, lead, nickel zinc identified.The results show leaching metals as function pH mainly depends mineralogical phases. On other hand, organic matter has influence in (for Ni, Cu Pb notably); presents adsorbent or complexation properties. Les éléments traces métalliques (ETM) constituent une environnementale pour le recyclage des mâchefers d'incinération déchets non dangereux (MIDND). L'étude de la spéciation ETM et facteurs qui contrôlent leur mobilité permet prédire comportement MIDND dans différentes environnementales suggérer ensuite élargir gestion. Une modélisation géochimique permis mieux comprendre ETM. Dans cette étude, les ciblés étaient baryum, cuivre, plomb, régissent ont été définis. résultats montrent que lixiviation métaux en fonction du dépend principalement phases minéralogiques ; matière organique joue également un rôle tant qu'adsorbant ou complexant certains (Ni, Pb, notamment). Mots-clés Mâchefers (MIDND), métalliques, capacité neutralisation acide, géochimique, PhreeqCI.

Distribution of Chloride in Municipal Solid Waste Incineration Bottom Ash
Chloride content is a critical problem for the reuse of incineration bottom ash as raw material in cement. The effect of dechlorination procedure largely depends on the existence form of the chlorides. However, limited information about the distribution and identity of chlorides in bottom ash can be obtained by bulk analysis methods. In this paper, the investigation towards a more comprehensive...
متن کاملProperties of Concrete with Municipal Solid Waste Incinerator Bottom Ash
The appropriate utilization of Municipal Solid Waste Incineration (MSWI) residues is a worldwide studied topic over the last decades. One of the possibilities is to use MSWI ashes in concrete production, as it is done with coal combustion products. The bottom ash features the most convenient composition for this purpose, and it is available in highest amounts among the MSWI ashes. Untreated bot...
متن کاملSize Distribution of Metals in Bottom Ash of Municipal Solid Waste Incinerators
Previous researches have examined the emission and management of heavy metals from municipal solid waste incinerations for compliances with regulations, and also, to address the concerns on various environmental issues. However, the size distribution of heavy metals in bottom ash has not been addressed to such extent yet. This study investigated the size distribution of bottom ash and also the ...
متن کاملMunicipal solid waste incineration bottom ash : Physicochemical characterization of organic matter
The aim of this work was to characterize the initial organic content of a selected municipal solid waste incineration (MSWI) bottom ash. This was realized by elemental carbon analysis using pyroanalysis of untreated samples. In addition, MSWI bottom ash extracts obtained by supercritical fluid extraction (SFE) or hot solvent extraction (Soxtec), were analyzed using gas chromatography (GC) coupl...
متن کاملFull Scale Tests of Short-Term Municipal Solid Waste Incineration Bottom Ash Weathering Before Landfill Disposal
Problem statement: Natural weathering is the most economic method of treatment in order to reduce the release of heavy metals present in the residue. Approach: The aim of the study was to optimize the minimum weathering times that were useful to reduce the lead release to within the Italian limits for landfill disposal. The mechanism of short-term weathering of MSWI bottom ash had been studied ...
