Solubility and adsorption characteristics of Pb in leachate from MSW incinerator bottom ash.
The solubility and adsorption characteristics of Pb in leachate from municipal solid waste incineration (MSWI) bottom ash was studied by batch experiments. The solubility of Pb in leachate was 1-2 orders of magnitude lower than that of Pb in carbonate solutions. Adsorption experiments showed bottom ash have high adsorption capacity for Pb. To evaluate a controlling component in bottom ash, quar...
متن کاملIncinerator Ash - Criteria of Performance
The object of this paper is to throw light on the criteria which apply to the degree of burn-out on a furnace burning mixed household and trade refuse. In particular, the paper concentrates on the ash discharged from the end of the grate since this represents the bulk of the ash produced by the plant. The classical approach to burn-out is to employ "carbon-in-ash" techniques familiar to combust...
متن کاملToxicity of leachate from bottom ash in a road construction.
A test road constructed with municipal solid waste incineration (MSWI) bottom ash was monitored over a period of 36 months. Using chemical and toxicological characterisation, the environmental impact of leachates from bottom ash was evaluated and compared with leachates from gravel used as reference. Initial leaching of Cl, Cu, K, Na, NH4-N and TOC from bottom ash was of major concern. However,...
متن کاملProduction of glass-ceramic from incinerator fly ash
Vitrification is one of the technological options for treating toxic waste. This paper reports the results of the feasibility study of utilizing fly ash from municipal waste incinerators by powder sintering technology. This process was used to transform vitrified incinerated fly ash into a CaO–Al2O3–SiO2 system of glass ceramic products. The major phase exhibited is gehlenite (Ca2Al2SiO7), whic...
متن کاملVitrification of Bottom Ash from A VR MSW incinerators
During incineration of municipal solid waste (MSW), various environmentally harmful elements and heavy metals are liberated either into bottom ash, or carried away with the off-gases and subsequently trapped in f ly ash. If these minor but harmf itl elements are not properly isolated and immobilized, it can lead to secondary environmental pol/ution to the air, soil and water. The stricter envi...
