综述了现有的氟化钙污泥处理处置技术，包括浮选富集回用氟化钙，熔融焚烧实现减量化，应用于陶瓷、水泥、混凝土制作，以及利用其化学性质，作为添加剂用于飞灰的固化稳定，或者在钢铁行业中充当萤石成为助熔剂。理论分析和试验检测表明上述方法均可实现含氟污泥的减量化、无害化、资源化，在处理氟化钙污泥时可以根据实际情况选择相应的工艺技术。

A review concerning the existing approaches to treat,recycle and utilize calcium fluoride sludge is given in this paper,including floatation to recycle CaF2 ,melting with waterworks sludge,recycling as additive in cement,concrete,porcelain and solidification-stabilization of fly ash,and acting as fluorite in steel-making.All these methods in this paper are feasible in theory and practice,providing a reference to the treatment and proposal of fluoride contaminated sludge.
