1. a kind of processing method of industrial waste salt, its concrete technical scheme is as follows:

  • Industrial waste salt is crushed into particle diameter to be less than0.5mm, is proportionally mixed with microwave absorption media particle, and being placed under air atmosphere in microwave heating equipment is carried out at microwaveReason, controls the temperature of mixture of abraum salt and microwave absorption media particle below 800 DEG C, in abraum salt in microwave processing processOrganic matter and it is degradable it is inorganic carry out microwave thermal decomposition, abraum salt particle is by the stirring in microwave heating appts in decomposable processEquipment is stirred continuously mixing, it is to avoid overheat locally occurs and causes abraum salt to melt, and microwave treatment time is 10min~5hr, microwaveThe gas produced in processing procedure is extracted out through air-introduced machine and sends into heat-accumulation combustion equipment or heat-storage catalytic combustion apparatus or straightCombustion gas processing device simultaneously degrades organic compound combustion therein, by heat-accumulation combustion equipment or heat-storage catalytic combustion apparatusOr the gas after direct-fired gas processing device treatment carries out desulphurization denitration depickling treatment according to its composition, removal may containSO2, qualified discharge after NOx, HCl, HF, it is microwaved after abraum salt eluriated through water, the sodium chloride dissolving discharge in abraum salt,The microwave absorption media particle in abraum salt is mixed in then by filtering or gravitational settling or centrifugation or Magnetic IsolationAnd recycle.
