摘　　要：以风电为代表的新能源产业近年来蓬勃发展。风电叶片材料中的环氧树脂具有稳定的化学结构,导致风电叶片在自然环境下的降解速度极为缓慢;随着风电叶片的大量服役,生命周期结束和报废的叶片由于无法处理而占用了大片土地,给环境造成了巨大的压力。本文通过梳理国家政策导向,指出了风电叶片回收的迫切性,列举了目前主流的风电叶片回收处理技术,包括机械回收、热回收、化学回收及可回收叶片技术等,系统性分析了各回收技术的差异,探讨了未来叶片回收领域的需求与发展前景。The new energy industry which represented by wind power has been booming in recent years.Due to the stable chemical structure of epoxy resin in wind power blade,the degradation of blades is extremely slow in natural environment.With large numbers of blades servicing,the end of life cycle and scrapped blades occupy a large area of land,causing the huge environment problem.By sorting out the national policy guidance,this paper points out the urgency of wind power blade recycling and lists the current blade recycling technologies,including mechanical recovery,pyrolysis,chemical recovery and recyclable blade.The review analyzes the differences among various recycling technologies systematically.This paper also discusses the demand in future and development prospects in the recycling field.
