Abstract

The invention provides a stabilization medicament for rubbish fly ash treatment. The stabilization medicament is characterized by comprising, by mass, 9-13 parts of sodium silicate and 1-4 parts of a sodium salt contained compound; and the sodium salt contained compound is one or more of sodium phosphate, sodium hydroxide, sodium sulphide, sodium thiosulfate and activated aluminum oxide. The invention further provides a method for treating fly ash through the stabilization medicament. According to the stabilization medicament and the method, ingredients and matching of the stabilization medicament are selected in an optimized manner, the sodium silicate and the sodium salt contained compound are mixed according to a certain proportion, the stabilization medicament can be used for activated silica aluminum calcium system dissociation of excitant fly ash, gel is formed, secondary pollution is avoided, the treatment cost is low, efficiency is high, and the treated fly ash is stable.

Description

technical field [0001] The application belongs to the field of environmental protection, and in particular relates to a stabilizing agent for garbage fly ash treatment and a method for treating fly ash using the same. Background technique [0002] At present, the main treatment technologies for waste incineration fly ash are: cement solidification method, chemical agent stabilization, melting solidification method and cement kiln co-processing method, etc. [0003] From the aspects of economy, ease of operation and site utilization, the cement curing method is one of the most suitable treatment methods. Foreign scientific researchers have done a lot of research on the use of cement solidification method to deal with fly ash. This method is also one of the commonly used methods for dealing with fly ash abroad. However, the capacity of the cement after curing is large, and if the fly ash contains components that hinder the normal coagulation of the cement, problems such as lo...
