摘要
硅物料固体废物种类繁多,给固体废物属性鉴别带来了困扰。本文以某未知含硅样品为研究对象,进行了物相结构、成分含量、粒度分布和微观形貌等理化特性分析,综合样品的外观及硅物料生产加工工艺,分析样品的可能来源,确定样品是来自或者掺杂了工业硅生产硅粉中回收的粉尘,属于固体废物。建立了进口粉末类含硅物料的固体废物属性鉴别方法,为进口固体废物监管提供技术支撑。
There are various types of solid waste deriving from silicon-containing materials,which brings dificulties to the identification of solid waste characteristics.In this paper,an unknown silicon-containing sample was taken as the research object,and physicochemical properties such as phase structure,component content,particle size distribution and micro-morphology were analyzed.In combination with the appearance of the sample and the producing and processing technology of silicon-containing materials,possible sources of the sample were analyzed.The results showed that the sample was the dust recycled during the production of silicon powder from industrial silicon,or was doped with the recycled dust.Thus,the sample belonged to solid waste.In conclusion,an identification method of solid waste characteristics for imported powder silicon-containing materials was established,providing the technical support for supervising and identifying the solid waste characteristics of silicon-containing materials,which had great significance for preventing the import of silicon-containing solidwaste.
