1、Modified Adsorption Materials: Activated alumina applicable at pH 5-8, with an F⁻ adsorption capacity of 6 mg/g. Single column operates for 72 hours, with effluent ≤1.5 mg/L.
2、Fluidized Bed Crystallization Process: Introducing seed crystals to promote calcium fluoride crystallization, reducing sludge production by 30% and enhancing fluoride ion removal rate to 90%.
3、Intelligent Regeneration System: Automatically identifies penetration points, reduces acid-base consumption by 40%, achieves 95% fluoride recovery from regeneration solution, and minimizes losses.
