摘要：For treating, particularly stablizing, material contain environmentally harmful components, especially from incinerating waste material, material iron cyanide and water processed wherein, and it stabilizes material washing and uses solution (generation) of the chemical method containing ferrous ion, allow to be formed stable iron oxide
(Fe+++) material in this way, the formation of the iron oxide is by being aoxidized property quality and quantity, temperature and pH relative to oxidant under controlled conditions, hereafter, if necessary, then processed material is subjected to heat treatment. A kind of equipment for implementing the above method includes that silo (2) containing material contain environmentally harmful components; Reactor (1) causes above-mentioned material to feed; Tank (9) and a return water tank (7) and storage bin
(3,4) containing ferrous salt solution and, if it is desired,Other chemicals, bath water and the chemicals (1) are sent to the reactor content, are stirring; Sedimentation basin (5) carries out bath water supply to it; Centrifuge or filter press (6), wherein being formed by sediment dehydration; It is reduced in pH value and oxidation water with the water of means in the cabinet (5) for inflating.
