The size distribution of polychlorinated dibenzo-p-dioxins and dibenzofurans in the bottom ash of municipal solid waste incinerators

Municipal solid waste incinerators (MSWI) produce by products which can be classified as bottom and fly ashes. The bottom ash accounts for 85-90 % of solid product resulting from MSW combustion. The objective of this study was to assess the feasibility of application of municipal solid waste incineration (MSWI) bottom ash as a supplementary cementations material for the preparation of blended cement. The used of bottom ash as a research material is caused by substances contained in cement is almost the same with bottom ash. Bottom ash was found to have some reactivity, but without greatly affecting the hydration process of OPC at 10 % replacement with 10% metakaolin is required to be used in the production of concrete in order to improve strength.

Melting Slag

Vitrification is considered to be an attractive technology for municipal solid waste incineration. The main components of the vitrified bottom ash slag are SiO2, CaO, Al2O3, Fe2O3, Na2O and MgO, accounting for more than 90% of the total mass. The phase relations and thermodynamic properties of the CaO-Al2O3-SiO2-FeOx-MgO-Na2O oxide system is highly required, and is of great significance for optimization of vitrification processing and sustainable resource utilization of melting slag. Thermodynamic properties of the vitrified bottom ash slag were investigated in the present work. A study on the phase equilibria of CaO-SiO2-Na2O system was carried out with modelling method.
