The typical fluoride-containing spent cathode from aluminum electrolysis industry is usually hard to be disposed, and a processing technique combining roasting and water leaching was adopted to remove fluorine in the spent cathode. The effects of parameters, including dosage of defluorination agent, roasting temperature, roasting time, liquid-solid ratio for water leaching, and water leaching time, on the fluorine content in water-leached residues were investigated. The results show that after 60 min roasting at 600 ℃ with 25% defluorinating agent, and 30 min water leaching with liquid-solid ratio of 8 L/kg, the leaching residue contains 1.12% fluorine and is mainly composed of carbon, calcium fluoride and sodium silicate aluminate, without leaching toxicity, which is ordinary solid waste. It is concluded that the processing technique consisting of roasting and water leaching can effectively remove fluorine from typical fluoride-containing spent cathode.

针对电解铝行业固体废物典型含氟废阴极的处置难题,采用焙烧-水浸工艺去除废阴极中的氟。考察了脱氟剂添加量、焙烧温度、焙烧时间、水浸液固比、水浸时间等参数对水浸渣中氟含量的影响。结果表明,在焙烧温度600 ℃、脱氟剂添加量25%、焙烧时间60 min、水浸液固比8 L/kg、水浸时间30 min条件下,水浸渣氟含量为1.12%。水浸渣主要由碳、氟化钙和硅铝酸钠组成,无浸出毒性,为一般固体废物。采用焙烧-水浸法实现了典型含氟废阴极中氟的有效去除。

针对电解铝行业固体废物典型含氟废阴极的处置难题,采用焙烧-水浸工艺去除废阴极中的氟。考察了脱氟剂添加量、焙烧温度、焙烧时间、水浸液固比、水浸时间等参数对水浸渣中氟含量的影响。结果表明,在焙烧温度600 ℃、脱氟剂添加量25%、焙烧时间60 min、水浸液固比8 L/kg、水浸时间30 min条件下,水浸渣氟含量为1.12%。水浸渣主要由碳、氟化钙和硅铝酸钠组成,无浸出毒性,为一般固体废物。采用焙烧-水浸法实现了典型含氟废阴极中氟的有效去除。

The typical fluoride-containing spent cathode from aluminum electrolysis industry is usually hard to be disposed, and a processing technique combining roasting and water leaching was adopted to remove fluorine in the spent cathode. The effects of parameters, including dosage of defluorination agent, roasting temperature, roasting time, liquid-solid ratio for water leaching, and water leaching time, on the fluorine content in water-leached residues were investigated. The results show that after 60 min roasting at 600 ℃ with 25% defluorinating agent, and 30 min water leaching with liquid-solid ratio of 8 L/kg, the leaching residue contains 1.12% fluorine and is mainly composed of carbon, calcium fluoride and sodium silicate aluminate, without leaching toxicity, which is ordinary solid waste. It is concluded that the processing technique consisting of roasting and water leaching can effectively remove fluorine from typical fluoride-containing spent cathode.
