Abstract

The invention provides a device for regenerating spherical hydroxyapatite for defluorination. The device comprises a defluorination reactor (1), a steam supply device (2), a steam generation device (3) and a water softener (4), wherein the steam supply device (2) is arranged at the bottom of the defluorination reactor (1); and the steam supply device (2), the steam generation device (3) and the water softener (4) are connected sequentially. According to the device for regenerating spherical hydroxyapatite for the defluorination, spherical hydroxyapatite is regenerated in a mode that steam is used for heating; the device has the characteristics of rapidness and high efficiency; and furthermore, the regeneration effect is improved greatly.

Description

technical field [0001] The invention relates to a material regeneration device, in particular to a spherical hydroxyapatite regeneration device for fluorine removal. Background technique [0002] The problem of fluorine pollution in groundwater in my country is serious, which seriously threatens the health of the people. Existing methods for defluoridation of groundwater include coagulation sedimentation, activated alumina adsorption, electrodialysis, reverse osmosis, ion exchange, adsorption, bone charcoal adsorption and zeolite defluorination, etc. However, there are problems such as complex process and high operating cost, which seriously restrict its further popularization and application. [0003] Hydroxyapatite, as a new economical and effective material for defluoridation of groundwater, has received widespread attention and achieved good application results. Since the material itself has no toxic effect and has a relatively high fluoride removal capacity, which can...
