Process for the preparation of a leaching-resistant solidification product of harmful waste sludges and cement

摘要

for water and saline solutions auslaugresistentes fixierungsprodukt toxic aqueous waste and cement with or without additives (fixierungs matrix):(a) a proportion of harmful waste from between 20 and 50 wt.%, in the case of pollutant laden lonenaustauscher as harmful wastes of between 26 and 50%.-%, relative to the dry weight of the waste in the final product (fixierungsprodukt) b) a moisture content in the final product, in accordance with a water to cement ratio in the range of 0.2 to 0.45.;the production of this fixierungsprodukte is characterised bythat the eindampfvorgang the aqueous waste and mixing with the fixierungs matrix at the same time at temperatures of 100 to 180 * c are carried out.
