The presoent invention relates to a building material made of mercury-containing sludge through the conversion treatment and its preparation method. It is characterized by that the mercury-containingsludge, sand, water and catalytic coagulating agent formed from magnesium oxide, magnesium chloride aqueous solutio, talcum powder, ferrous sulfate, trisodium phosphate, sodium polyphosphate, phosphoric acid, aluminium trichloride and 191 resin are fully stirred, press-moulded and cured so as to obtain the required building material.
Description
technical field [0001] The present invention relates to the utilization technology of solid waste, more precisely to a technology of converting mercury-containing sludge into building materials. Background technique [0002] At present, the amount of solid waste in the petroleum industry is large, the level of treatment and disposal is low, the comprehensive utilization is small, the land occupation is large, and the harm is serious. It is one of the main environmental problems in China. The stacking of petrochemical waste not only occupies a large amount of land, but also the waste is wetted by rain and snow to leach poisons, which will poison, acidify, and alkalize the land. Solid petrochemical waste also pollutes the atmosphere very seriously. Among various solid wastes, the most serious one is the pollution of hazardous wastes. Flammable, explosive and corrosive highly toxic wastes can easily cause serious disasters to the environment in real time, and the hazards of t...
