Safety treatment method for fluorine-containing solid waste
The invention relates to a safety treatment method for fluorine-containing solid waste. According to the method, a calcium compound is added into the fluorine-containing solid waste, and a composition fluorine ions in the fluorine-containing solid waste and calcium ions in the calcium compound form a water-insoluble compound calcium fluoride, so that free fluorine ions in the fluorine-containing solid waste are greatly reduced, and the phenomenon that the fluorine ion content of the fluorine-containing solid waste is large and the fluorine-containing solid waste is easily dissolved in soil and groundwater to cause pollution in the prior art is avoided; a curing agent is added to achieve the effect of bonding the fluorine-containing solid waste, and meanwhile, a layer of low-permeability substance is formed on the surface of the fluorine-containing solid waste to limit the transfer of harmful compositions, mainly the fluorine ions, in the fluorine-containing solid waste, so that soil and underground pollution is also avoided.
