Abstract:
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.[著者文摘]
Key words:
：waste electric and electronic equipment; resources recycling ;discarded PCB ; reutilization; separation
