某双氧水生产线废氧化铝危险特性鉴别实例分析及研究
Case Analysis and Research on the Identification of Hazardous Characteristics of Waste Aluminum Oxide from a Hydrogen Peroxide Production Line

某企业有一条双氧水生产线，双氧水的生产采用2-乙基蒽醌法，含2-乙基蒽醌的工作液首先在催化剂作用下，与氢气经加氢反应生成2-乙基氢蒽醌，2-乙基氢蒽醌再与空气中的氧气发生氧化反应，2-乙基氢蒽醌氧化为2-乙基蒽醌，同时生成双氧水，再经萃取、浓缩得到70%的双氧水。生产过程中产生废氧化铝，为了解废氧化铝的危险特性，通过原辅材料分析、工艺产品及副产物分析及样品检测，进行危险特性鉴别，得出鉴别结论，为后续废氧化铝科学合理的综合利用或处置提供重要技术依据。
A certain enterprise has a hydrogen peroxide production line. The production of hydrogen peroxide adopts the 2-ethylanthraquinone method. The working solution containing 2-ethylanthraquinone is first hydrogenated with hydrogen gas under the action of a catalyst to generate 2-ethylanthraquinone. 2-ethylanthraquinone then undergoes an oxidation reaction with oxygen in the air. 2-ethylanthraquinone is oxidized to 2-ethylanthraquinone, and hydrogen peroxide is gener-ated. After extraction and concentration, 70% hydrogen peroxide is obtained. Waste alumina is generated during the production process. In order to understand the hazardous characteristics of waste alumina, hazardous characteristics are identified through analysis of raw and auxiliary materials, analysis of process products and by-products, and sample testing. Identification conclusions are drawn, providing important technical basis for the scientific and reasonable comprehensive utilization or disposal of waste alumina in the future.
