中文摘要: 采用氢氧化钠和碳酸钠混合碱液洗涤脱除次氧化锌中的氟氯。在碱液中氢氧化钠和碳酸钠摩尔比为1︰1，控制液固比、洗涤温度时，氟、氯脱除率分别为92.31%和96.57%。碱洗液经沉锌、沉氟、沉氯处理，溶液中锌、氟、氯的浓度分别为0.37、0.048、0.083 g/L。采用锌电解废液浸出经碱洗脱除氟氯后的次氧化锌，控制电解废液硫酸浓度、液固比、浸出温度，浸出液中锌、铅、氟、氯的浓度分别为86.27 g/L、0.027 g/L、0.042 mg/L、0.078 mg/L，浸出渣中锌和铅含量分别为9.13%和50.84%，锌和铅回收率分别为95.36%和96.57%。
Abstract:Fluorine and chlorine in zinc suboxide were removed by cleaning with mixed solution of NaOH and Na2CO3. Fluorine and chlorine removing efficiency is 92.31% and 96.57%, respectively under the conditions of molar ratio of NaOH and Na2CO3 of 1︰1 and controlled L/S and temperature. Concentration of zinc, fluorine and chlorine in alkaline cleaning solution is 0.37, 0.048, and 0.083 g/L after precipitating. Zinc suboxide whose fluorine and chlorine were removed was leached with zinc electrolytic waste liquid by controlling H2SO4 concentration, L/S and temperature of leaching. Zinc, lead, fluorine and chlorine concentrations in leaching solution are 86.27 g/L, 0.027 g/L, 0.042 mg/L, and 0.078 mg/L. Zinc and lead content in leaching residue is 9.13% and 50.84%, respectively. Recovery efficiency of zinc and lead is 95.36% and 96.57%, respectively.
