Modified waste incineration fly ash coupling mineralization resource utilization method and application
The invention relates to a modified waste incineration fly ash coupling mineralization resource utilization method and application. The method comprises the steps that waste, siliceous modified solid waste and a doping agent are mixed and incinerated, an obtained incineration product is mixed with siliceous solid waste and water, digestion and compression molding are conducted, finally, a carbon dioxide pressurization mineralization reaction is conducted, and a mineralized product is obtained. Compared with the prior art, the modified waste incineration fly ash coupling mineralization resource utilization method has the advantages that resource utilization of waste incineration fly ash, solid waste and industrial flue gas is combined, so that the activity problem of the waste incineration fly ash in the resource utilization process is solved; the composition of active ingredients in the waste incineration fly ash is optimized by adding the modified solid waste, and the resource utilization of the waste incineration fly ash is realized in a real sense by combining a mineralization process; and the treatment process and the treatment cost of the emissions are reduced, and industrial energy conservation, efficiency improvement and green low-carbon development are promoted.
本发明涉及一种改性垃圾焚烧飞灰耦合矿化资源化利用的方法与应用，方法包括：将垃圾与硅质改性固废、掺杂剂混合并焚烧，所得焚烧产物再与硅质固废、水混合，再经消解、压制成型，最后进行二氧化碳加压矿化反应，得到矿化产品。与现有技术相比，本发明提供了一种改性垃圾焚烧飞灰耦合矿化资源利用的方法，该方法将垃圾焚烧飞灰、固体废弃物、工业烟气的资源化利用结合，不仅解决了垃圾焚烧飞灰在资源化利用过程中的活性问题，还通过加入改性固废优化了垃圾焚烧飞灰中活性成分的组成，结合矿化工艺在真正意义上实现了垃圾焚烧飞灰的资源化利用；并减少了以上排放物的处理工艺和处理成本，有利于推进工业节能提效和绿色低碳发展。
