Resource utilization method of household garbage incineration residue sorting tailing
The invention relates to a resource utilization method of household garbage incineration residue sorting tailing. The household garbage incineration residue sorting tailing is subjected to fine grinding treatment and is directly dried by utilizing hot smoke, the obtained residue micro powder is forcedly mixed with cement, and processes such as pulping, bubble forming, mixing and soaking, casting moulding, low-temperature oxygen steaming, normal-temperature maintenance and the like are carried out, so that a foam concrete block or a thermal insulation material is prepared. The resource utilization method of the household garbage incineration residue sorting tailing has the advantages that negative effect of free calcium oxide and magnesium oxide on quality of foam concrete is eliminated, and final strength of a foam concrete product is improved; under the combined action of hydration products of cement, and toxic trace heavy metals are solidified, so that a tailing product produces no secondary pollution to the environment; and residue adding proportion is high, resource utilization and large-scale treatment on the garbage incineration residue sorting tailing can be realized, technology is simple, product cost is low, and good economic benefit and environmental benefit are realized.
