摘要
给出了电子废弃物的定义、分类和来源,指出电子废弃物具有数量多、危害大、潜在价值高和处理困难的特点。介绍了电子废弃物资源化研究的概况和技术,针对电子废弃物资源化中的难点--废弃印刷电路板,提出了破碎-磁选-电选—高效离心分选的联合流程从电路板中回收金属富集体的思路。
The definition,sort and source of "waste electric and electronic equipment"(WEEE)were described, the characteristics with abundant,hazard,high potent value and difficult recovery of WEEE were introduced. The research situation and techniques of reutilization of WEEE were depicted.The discarded printed circuit boards (PCB) are regarded as the most difficult to WEEE reutilization,the flowsheet of "shredding-magnetic separation-electrostatic separation-effectual centrifugal separation" was brought forward to recovery metals from discarded PCB.
