Hazardous Wastes Recycling by Solidification/Stabilization Method
Keywords:
solidification/stabilization, hazardous waste, leaching tests, waste disposal, waste treatment.Abstract
The solidification/stabilization (S/S) method is used for treatment of various types of wastes. This paper deals with S/S
of the selected type of hazardous waste – sludge from biological industrial waste water treatment with the content of
hazardous substances. The aim of this research is to develop the technology for this type of industrial hazardous wastes
disposal using S/S method on qualitatively new technological level. The classic fly ash, fluid fly ash (secondary raw
materials) and cement were chosen as suitable solidification agents. The efficiency of these solidification binders was
improved by the specific surface increasing. Leaching tests were used for verifying the efficiency of solidification
formulas.
