摘要
中国电解铝产量位于世界之首,电解铝是传统的“两高”产业。电解铝产业排放氟化物引起的环境污染问题一直备受关注,本文就电解铝产业目前的生产工艺、清洁生产指标、污染物排放控制、固废处置等方面进行认真梳理,剖析氟化物在生产工艺中的输入和输出节点,总结氟化物在各节点的控制措施和特点,结合目前所采取的环保措施和部分项目的研究成果,对电解铝项目氟化物排放控制提出下一步建议,减缓电解铝项目对生态环境的破坏和大气环境的污染。
China's electrolytic aluminum production ranks the first worldwide,and electrolytic aluminum is traditionally considered as a high-pollution&high-consumption industry.Environmental pollution problems caused by fluorides emission in electrolytic aluminum industry have attracted much attention.This paper presents the current production process,clean production index,pollutant emission control and solid waste disposal in electrolytic aluminum industry,analyzes fluoride input and output steps in the production process,summarizes the fluoride control measures and characteristics therein.Combined with the current environmental protection measures and part of the project research results,the next step suggestions are propsed for the fluorides emission control in electrolytic aluminum projects,thus alleviating the damage caused by aluminum projects to the ecological environment and atmospheric environmental pollution.
