At present, there are enterprises in the industrial waste salt disposal technology has a successful case. They feed polycarbon by-products salt and MDI waste salt as raw salt into the ionic membrane plant, or use the diaphragm alkali plant to treat the saline wastewater of epoxy resin, or use the organophosphorus by-products salt for ionic membrane and alkali production. Other enterprises should also strengthen the research on the centralized disposal of waste salt.
In view of the technologies needed in the future, comprehensive utilization and resource recovery technologies should be promoted to realize the recycling and high-value utilization of wastes. Mother liquor and waste salt with high salt content should be treated first, and attention should be paid to resource utilization; Encourage the use of catalytic oxidation, high temperature incineration, adsorption and desorption, separation (crystallization) and other technologies to prepare industrial by-products that meet standards; Encourage the chlor-alkali and soda ash industries to make use of their advantages in brine purification, digestion, calcining and other facilities to cooperate in the disposal of waste salt produced by other industries and realize the comprehensive utilization of salt resources; Speed up the demonstration and promotion of polycarbonate, epoxy resin and MDI waste salt for caustic soda production; The application of pesticide waste salt to caustic soda and soda ash in ionic membrane process was explored. Research on salt-containing wastewater treatment and discharge technology should be carried out in areas where conditions permit, so as to realize natural circulation.
The above is the introduction of industrial waste salt disposal technology manufacturers. I hope you'll like it.
