【摘要】 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。更多还原

【Abstract】 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.更多还原
