Title:
JOINT DISPOSAL METHOD FOR HAZARDOUS WASTE INCINERATION RESIDUES AND SOLID WASTE, CERAMSITE, AND USE THEREOF
Document Type and Number:
WIPO Patent Application WO/2021/073039
Kind Code:
A1
Abstract:
A joint disposal method for hazardous waste incineration residues and solid waste, prepared ceramsite, and use thereof, which belong to the field of resource environments. The disposal method comprises the following steps: mixing hazardous waste incineration residues and solid waste, and successively pelletizing, drying, and calcinating the obtained mixed materials, so as to obtain ceramsite. In the preparation of ceramsite by joint treatment using hazardous waste incineration residues and solid waste as raw materials, heavy metal contained in the hazardous waste incineration residues and solid waste is reduced and solidified while breaking down dioxin and organic matter in the hazardous waste incineration residues and solid waste, solving the difficulty of disposal of hazardous waste incineration residues and solid waste, saving a large amount of land for filling, reducing the cost for comprehensive disposal, and new hazardous waste is not produced, reducing the burden of the ecological environment.
