Ceramic product made of dangerous wastes and solid wastes

Abstract

The invention discloses a 'ceramic product made of dangerous wastes and solid wastes', and relates to a ceramic product made of various dangerous wastes, solid wastes and soil polluted by the dangerous wastes by a traditional ceramic production process. The ceramic product comprises an art ceramic product, a chemical ceramic product, a filling ceramic product in a heat exchange or mixing or reaction device, a building ceramic product, a sanitary ceramic product, a daily ceramic product, a ceramic solar panel product and an infrared emitter ceramic product. Total chromium in leach liquor of the ceramic product is less than 1.5mg / L, hexavalent chromium is less than 0.5mg / L, barium is less than 10mg / L, nickel is less than 0.3mg / L, copper is less than 20mg / L, manganese is less than 40mg / L, mercury is less than 0.03mg / L, zinc is less than 40mg / L, lead is less than 0.15mg / L, cadmium is less than 0.1mg / L, beryllium is less than 0.012mg / L, arsenic is less than 0.2mg / L, and selenium is less than 0.7mg / L.

Description

technical field [0001] This technical solution involves the treatment of various hazardous wastes, solid wastes, and production of ceramic products, especially the use of various hazardous wastes and solid wastes as raw materials or one of the raw materials to produce various ceramic products, eliminating harmful substances during the production of ceramic products, Get Safe Ceramics. Background technique [0002] At present, hazardous waste, solid waste, incineration fly ash, and residues are often landfilled in waste disposal centers in China. However, landfills need to be managed, and the long-term cost is high. It is also a major hidden danger of land pollution. All hazardous waste must be dug out eventually. Re-governance, we and future generations will pay a huge price. my country's industry and population are concentrated in the eastern region, producing a large amount of industrial waste, domestic waste, fly ash from incineration waste, and sludge from sewage treatm...

Problems solved by technology

A large amount of chromium slag that has been landfilled has left major pollution hazards to the land and groundwater. Tens of millions of tons of chromium slag cement have been scattered all over the country, leaving irreparable future troubles. The chromium slag bricks that are not completely detoxified are continuous Hexavalent chromium pollution source
