At present, there was a stirring of interest in green wave; environmental problem has attracted a great deal of attention in all countries, and placed on the world agenda, scrap electronic products are one of the fastest growing Solid waste, Its unreasonable disposal and utilization has caused increasingly serious problem of environmental pollution, In recent years, the world started to pay attention to the electronic products in the state after retirement, The European Union enacted the WEEE and ROHS directives require all kinds of electronic products must be recycled and prohibit the use of materials. In this trend, China began to issue the relevant management regulations.Retired electronic products utilization, recycling is a key link is the most difficult part of. Only retired from all walks of life electronic product recycling channels together, concentrated dismantling and processing, and thus effective control of environmental pollution. Thus, the solution of the demolition and recycling of retired electronic products is the key to its resources.This paper use from the hazards of retired electronic products and recycling point of view, an overview of the pollution status of the current home and abroad a huge number of retired electronic products and their recycling processing technology, and combined with the actual from retired electronic products recycling systems and resources to deal with technical aspects of the feasibility of proposals and ideas.Author by reading the relevant literature, analysis of the characteristics of electronic products, including the demolition, crushing and sorting process, including the environmentally friendly and economically viable mechanical and physical recovery process. Physical methods of treatment and recovery retired electronic products, equipment and processes, The main including the crushing and separation of the of electronic circuit board, to use the dry method and wet method sorting technology to separation the and so on as metal and non-metallic; Circuit board through the mill broken, then the next screening; Through the study of retired electronic products recycling process planning, the modular recovery mode, Including the process of recycling plastic, compressor, freon, circuit boards, power cord, display, metal casing, etc. And the retired electronic products recycling cost-benefit assessment of research and analysis, the establishment of the relevant model.Disassembly and recycling methods studied in this thesis aimed at resource use and management of electronic products after retirement, Feedback and the various components of these electronic products hazards and pollution control measures, to designers and manufacturers, in order to design more environmentally friendly products.
