破碎分选技术在废弃电器电子产品再生利用中应用

Separation and Crushing Techniques in WEEE Processing and Recycling

废弃电子电器产品因其含有的各类重金属物质和难降解有机物,得不到合理处理处置的话,会对环境产生严重不良影响,但也正因为其物质种类繁多,为其回收处理增加了难度。在常规的处理方法中,物理方法由于不涉及物质化学结构发生变化,对环境的影响相比化学方法要小,如果技术选用得当,将能有效避免环境质量损害,产生可观的经济效益。

Various heavy metal materials and refractory organics in waste electronic and electric equipment can cause severe damage to the environment if not properly treated. Furthermore, the great variety makes recycling even more difficult. Among all conventional processing methods, physical processing has less impact on the environment than chemical processing as there is no change in chemical structures. If properly selected, physical processing will be able to avoid environmental pollution effectively and also produce great economic benefit.
