AI Technical Summary
Traditional molecular sieve ion exchange processes suffer from problems such as long exchange cycles, low resource utilization, high environmental costs, high production energy consumption, and complex wastewater treatment. In particular, it is difficult to achieve efficient and comprehensive utilization of organic template agents and silicon-aluminum sources, leading to resource waste and environmental pollution.
The cerium-modified cation exchange resin in the rare earth ion recovery unit is used to adsorb the molecular sieve metal ion exchange waste liquid. Combined with the desorption and rinsing mechanism, the resin is regenerated by sodium hydroxide solution. The adsorption and desorption processes are optimized by temperature control to realize the recycling of the resin.
It improves waste liquid treatment efficiency, reduces resource waste, lowers production costs, enhances resource recycling rate and environmental protection effect, and simplifies waste liquid treatment process.
