AI Technical Summary

Technical Problem

Existing drinking water defluoridation equipment has low defluoridation efficiency and complex regeneration operation in the low-temperature environment of Inner Mongolia. Furthermore, the single-layer adsorption medium has limited removal capacity, making it difficult to meet the requirements of high-fluoride water quality.

Method used

The system employs a composite adsorption layer design, comprising a first activated alumina layer, a modified zeolite molecular sieve layer, and a second activated alumina layer. Combined with an insulation system and a regeneration system, the system utilizes a solar-heat-absorbing coating to maintain the equipment temperature, enabling in-situ regeneration and simplified maintenance.

Benefits of technology

It maintains high defluoridation efficiency in extremely cold environments, with effluent fluoride concentration below 0.8 mg/L, simplifying equipment maintenance and reducing operation and maintenance costs.
