摘　　要：为确定新液混入废电解液后,电解液中氟离子浓度升高的影响因素,考察了脱氟渣水洗、酸洗、沉降时间对脱氟后液氟离子浓度的影响、酸度对溶液中氟离子浓度的影响、过滤材质对滤液中氟离子浓度的影响,结果表明:脱氟渣遇酸后氟会溶解,导致电解液中氟离子浓度升高;氟离子浓度随着沉降时间延长而降低,新液至少沉降2 h以上再投入使用;过滤材质对溶液中氟离子浓度影响不大。When new liquor is mixed with waste electrolyte,the concentration of fluorine ions in the electrolyte increases.The following factors were investigated to confirm their influence on the increase in fluorine ion concentration:effect of washing,pickling and settlement time of defluorinated slag on fluorine ion concentration in defluorinated post-liquid;effect of acidity on fluorine ion concentration;effect of filtration material on fluorine ion concentration,results show that fluorine dissolves when defluorinated slag mixed with acid,so the fluorine ion concentration shall be increased in electrolyte;fluorine ion concentration shall decreased along with the prolonging sedimentation time,so new liquid shall be feed into process after sedimentation more than 2 h;the filtration material's impact on fluorine ion concentration is not significant.
