摘要
电解铝大修渣(SPL)中含有超标的可溶性氟化物、氰化物等,是一种危险废物,需要对其中有害物质进行脱除或减量化。阐述了SPL的来源、组成及对环境的影响,综述了不同处理法各自的特点,并结合各方法的优缺点对湿法、火法处理SPL做了适用性分析,为其无害化、资源化提供了建议,并分析了发展趋势。
The electrolytic aluminum spent pot lining(SPL)is a kind of hazardous waste,containing excessive soluble fluoride,cyanide substances,and it is necessary to remove or reduce the harmful substances.The source,composition and impact on the environment of SPL are expounded,the characteristics of different treatment methods are summarized and the advantages and disadvantages of each method are combined to analyze the suitability of Wet process and Pyroprocess of SPL.The suggestions are put forward for its harmlessness and recycling,and the trend of development trend is analyzed.
