【摘要】 通过对不同氟化企业含氟污泥的理化特性分析,得出污泥中都有较高含量的CaF2(干污泥的60%以上),如果直接填埋,不但是一种资源的浪费,更易造成环境的二次污染。并通过试验研究提出了三种可资源化利用途径:一是集中污泥进行浮选富集,回用于氟化工生产;二是作为助剂直接应用于硅酸盐工业;三是作为降熔点剂应用于钢铁生产工业。更多还原

【Abstract】 Through analyzing the features of mud with fluorine from different enterprises,there arises a conclusion that the mud is rich in high CaF2(more than 60% in dried mud).If directly filled in land,the mud with fluorine may lead to secondary pollution of the environment as well as be a waste of resource.In this paper,two ways of its recycling treatment are proposed.First,the mud with fluorine can be used in chemical production through flotation collecting;Secondly,to apply it to cement industry as auxiliary;Thirdly,to steel production industry as melting point drop.更多还原
