铝电解厂排放的含氟烟气是冶金企业重大污染物之一。按我国铝厂生产能力计算,每年排入大气的氟化物(按F计)近一万吨。因其排放量大,毒性大,危害严重,业已引起有关方面的重视。 Flue gas emissions from aluminum electrolysis plants are one of the major pollutants in metallurgical enterprises. Calculated according to the production capacity of China’s aluminum production, annual fluoride emissions into the atmosphere (by F meter) nearly 10,000 tons. Because of its large emissions, toxicity, serious harm, has drawn the attention of the parties concerned.
