摘要
废电路板有色金属资源化回收利用过程中,会产生大量冶炼炉渣。针对《国家危险废物名录》(2021年版)实施后有色金属资源化回收冶炼炉渣的下一步安全处置方式、危险特性不明等问题,选取国内某典型电子危险废物治理企业富氧侧吹冶炼炉渣为研究对象,通过采集100个样品进行元素种类和腐蚀性、毒性特性测试,得出该冶炼炉渣不具有危险废物鉴别标准规定的危险特性,可按照一般工业固体废物进行管理的结论。该结论有助于冶炼炉渣的危险特性判断和环境监管,也为冶炼炉渣类无害化处理和资源化利用提供了技术指导。
In the process of recycling non-ferrous metals from waste circuit boards,a large amount of smelting slag will be produced.In view of the further safe disposal methods and unclear hazardous characteristics of smelting slag after the implementation of the National Hazardous Waste List(2021 edition),a typical electronic hazardous waste treatment enterprise with oxygen-rich side-blowing melting technology was selected as the research object and 100 samples were collected to test the element types,corrosion and toxicity characteristics.It is concluded that the studied smelting slag is not hazardous waste according to the corresponding standards and can be managed as industrial solid waste.The results are not only helpful for the identification of hazardous characteristics and environmental supervision of smelting slag,but also provide technical guidance for their harmless disposal and resource utilization.
