Solid waste-based porous glass ceramic as well as preparation method and application thereof

The invention provides solid waste-based porous glass ceramic as well as a preparation method and application thereof, and belongs to the technical field of solid waste utilization. Comprising the following steps: (1) mixing a foaming agent A and a foaming agent B, and carrying out primary ball milling to obtain a composite foaming agent; and (2) mixing the composite foaming agent obtained in the step (1) with solid waste, carrying out secondary ball milling, and sintering to obtain the solid-waste-based porous glass ceramic. The composite foaming agent is adopted for foaming, the two components are subjected to a high-temperature deoxidation reaction and a high-temperature oxidation reaction respectively, the evenly-mixed composite foaming agent can be obtained through pre-ball-milling mixing, the composite foaming agent and the solid waste are evenly mixed in combination with secondary ball milling, and overgrowth of bubbles can be effectively prevented; the preparation method has the advantages that the un
