Stabilization/Solidification of Waste Incinerator Salt and Ash by Asphalt Emulsions

Popis výsledku v původním jazyce

A procedure for S/S of salt and ash from a waste incinerator by aqueous asphalt emulsions was developed. The procedure consists of mixing waste with an anionic slow setting emulsion, whereby a partial coating of waste particles with asphalt binder is obtained. The dough-like mixture thus formed is subsequently provided with an asphalt coating by means of spraying with an anionic rapid setting emulsion. The asphalt coating is impermeable and presents a secondary immobilizing barrier effectively preventing any pollutant getting leached by aqueous solutions. Leachability tests performed on specimens of stabilized salt, stabilized ash, and on an asphalt-coated glass body as blank test show very low values of parameters being determined. In addition, the values of these parameters for both wastes and blank test are the same and thus convincingly demonstrate both the efficiency and universal applicability of the elaborated S/S procedure. Ecotoxicity tests indicate the toxicity of both stabil
