▎ 摘　　要

NOVELTY - Deep fluorine removing technique of fluorine-containing wastewater, comprises contacting aluminum source fluorine removing agent and fluorine-containing wastewater with aluminum ion and fluoride ion complex to remove fluoride ions in fluorine-containing wastewater in which aluminum source fluorine removing agent is aluminum-metal organic frameworks (Al-MOFs)/graphene composite material. USE - The deep fluorine removing technique of fluorine-containing wastewater is useful for aluminum source fluorine removing agents (claimed). ADVANTAGE - The deep fluorine removing technique of fluorine-containing wastewater adopts existing lime-poly aluminum chloride (PAC) combined fluorine removing method; aluminum source fluorine removing agent adsorbs fluoride ions in fluorine-containing wastewater, thus reduces fluoride ions in fluorine-containing wastewater to less than 1mg/l to reach discharge standard. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for aluminum source fluorine removing agent.
