Abstract

It known to add fly ash and cement to pollutants from gas desulphurisation plants, such as calcium chloride, sodium chloride, sodium sulphate and other calcium salt compounds so that leaching is very largely prevented. In order to inhibit this leaching as far as possible, according to the invention it is proposed that fillers of known type, such as filter ash, cement, gypsum, calcium sulphate dihydrate and similar substances are added to the mass to be landfilled and, to increase the leaching resistance, after addition of a small amount of sodium polyacrylate, preferably in a wetted form, are additionally then mixed and shaped.

Description

Es ist bekannt, Schadstoffe aus Rauchgasentschwefelungs­ anlagen, wie Calciumchlorid, Natriumchlorid, Natrium­ sulfat und andere Calciumsalzverbindungen mit Flug­ asche und Zement zu versetzen, damit eine Auslaugung weitgehend vermieden wird.It is known to pollutants from flue gas desulfurization plants, such as calcium chloride, sodium chloride, sodium sulfate and other calcium salt compounds with flight to add ash and cement to allow leaching is largely avoided.

Um diese Auslaugung noch weiter zu bremsen, wird er­ findungsgemäß vorgeschlagen, zu diesen vorgenannten Mischungen ein Natriumpolyacrylat zuzusetzen, das vorzugsweise in vernetzter Form Anwendung findet.To slow this leaching even further, he will proposed according to the invention to these aforementioned Add a sodium polyacrylate to mixtures that preferably used in cross-linked form.

Es wurde gefunden, daß durch den Zusatz die Auslaugungs­ festigkeit dieser zementhaltigen Massen erheblich ge­ steigert wird und vor allem dadurch, daß das zugesetzte vernetzte Natriumpolyacrylat erhebliche Wassermengen, die in die Pellets oder Steinkörper eingedrungen sind, binden und halten.It was found that leaching by the addition strength of these cement-containing masses considerably is increased and above all by the fact that the added  cross-linked sodium polyacrylate considerable amounts of water, which have penetrated into the pellets or stone bodies, tie and hold.
