Embodiment 1

[0018] In parts by weight, mix 30 parts of solid waste (fly ash from incineration), 10 parts of coke, 30 parts of cement, 10 parts of fluorite, 10 parts of limestone, and 10 parts of steel slag, and heat at high temperature (1200-1400°C) It is melted and reduced at a high temperature to obtain a molten substance, and then separated and cooled by the difference in specific gravity to obtain a metal alloy and a mineralized glass body.

Embodiment 2

[0020] In parts by weight, mix 40 parts of solid waste (fly ash from incineration), 10 parts of coke, 30 parts of cement, 5 parts of fluorite, 5 parts of limestone, and 10 parts of steel slag, and heat at high temperature (1200-1400°C) It is melted and reduced at a high temperature to obtain a molten substance, and then separated and cooled by the difference in specific gravity to obtain a metal alloy and a mineralized glass body.

Embodiment 3

[0022] In parts by weight, mix 45 parts of solid waste (electroplating sludge), 10 parts of coke foam, 30 parts of cement, 10 parts of fluorite, 5 parts of limestone, and 10 parts of steel slag, and heat to melt at high temperature (1200-1400°C) It is reduced at high temperature to obtain molten material, and then separated and cooled by the difference in specific gravity, to obtain a metal alloy and a mineralized glass body.

Abstract

The invention discloses an auxiliary for resourceful treatment of solid waste. The auxiliary comprises, by weight, 3-10 parts of coke foam, 10-40 parts of cement, 3-10 parts of fluorite, 3-10 parts of limestone and 3-10 parts of steel slag. 30-78 wt% of the solid waste and the balance auxiliary are mixed, heated to be melted at a high temperature, and separated and cooled to obtain metal alloy and a mineralization glass body. Compared with an existing auxiliary, the slagging function, the reduction function and the liquidity can be improved through the auxiliary adopted for processing the mineralization glass body, so that the melting capability and the reduction capability of the solid waste and the curing effect of a mineralization glass body product on heavy metal ions are improved, leaching of toxic elements in the mineralization glass body product is reduced, and the environmental governance requirement of the mineralization glass body product is met.

Description

Technical field [0001] The invention belongs to the field of pollution control, and specifically relates to an auxiliary agent for resource-based treatment of solid waste. Background technique [0002] my country produces a large amount of solid waste every year, causing serious environmental and geological hazards, and occupying a large amount of land. The currently widely used incineration treatment cannot solve the problem of harmlessness at one time. The resource-based treatment of solid waste mineralized glass product technology is a new type of harmless treatment method for solid waste. This technology can reduce heavy metals and destroy organic matter, seal heavy metals, and greatly reduce the volume of waste. It is especially suitable for The fly ash produced by incineration, hazardous waste containing heavy metals and other toxic substances, uses high temperature and other means to reduce the solid waste into metal alloys and mineralized glassy products with amorphous s...
