Abstract
The invention relates to the technical field of fluorine-containing sewage treatment, and discloses a recyclable defluorinating agent and a preparation method thereof. The defluorinating agent comprises the following raw materials: activated silicic acid, deionized water, an organic polymer flocculant, and a fluoride ion adsorbent. The invention allows the prepared defluorinating agent to have excellent adsorption capacity by involving the fluoride ion adsorbent in the preparation process of the defluorinating agent, significantly improves the removal efficiency of fluoride ions in sewage, can also remove heavy metal ions in sewage, improves the possibility of coordinated treatment of multiple pollutants in sewage, reduces the complexity of subsequent treatment, significantly accelerates the speed of sewage treatment, and solids generated by filtering the treated sewage contain heavy metal ions and rare earth resources, have excellent recyclable value, can realize the recycling of resources, greatly reduce the environmental burden, and provide strong support for the protection of water resources and the environment.
