摘　　要：通过对产生氟化钙污泥的典型行业调研取样分析含氟污泥组成,得出污泥中Ca F2质量分数占干污泥45%以上,具有较大的资源化价值。综述现有氟化钙污泥资源化技术,包括制砖、硅酸盐工业、钢铁工业、制造吸附剂、浮选富集氟化钙和生产氟化钙,具有一定的理论和实践依据,能够实现含氟污泥减量化、无害化、资源化。Through the survey sampling analysis of fluoride-containing sludge produced by the calcium fluoride sludge typical industry,the results show that the Ca F2 mass fraction in the sludge accounts for more than 45% of the dry sludge,then it has a great resource value.Reviewing the currently existing calcium fluoride sludge reclamation technology,including brick,silicate industry,steel industry,manufacturing adsorbents,flotation enrichment of calcium fluoride and the production of calcium fluoride,they have some certain theoretical and practical basis and can actualize the fluorine-containing sludge reduction,harmless,resource utilization.
