摘　　要：为解决废弃聚苯硫醚(PPS)纤维和滤袋通过焚烧或填埋方式处理,造成资源浪费和二次污染等问题,促进废弃PPS纤维的高效高价值回收利用,对目前国内外废弃PPS纤维回收再利用的研究现状进行综述。阐述了废弃PPS纤维的回收再利用方法,主要包括化学溶解、化学分解、机械粉碎、纤维拆解、熔融加工和直接利用,并梳理分析了不同方法的优缺点及其回收制品的特点;然后分别从废弃滤袋清灰处理、滤袋纤维成分复杂和回收利用成本高3个方面分析影响废弃PPS纤维回收再利用的技术难点;最后提出建立PPS滤袋生产、使用和回收三方企业的联动机制,根据不同工况条件分层分类管理回收废弃PPS滤袋,以期为PPS纤维的高值回收利用提供参考。Significance High-temperature dust is the characteristic of air pollutants discharged by industry.Bag-type dust removal systems have been widely used in high-temperature dust treatment of waste incineration plant,steel plant,cement plant and coal-fired power plant,due to effectiveness and low cost.Filter bags are the key material of bag dust removal system.Polyphenylene sulfide(PPS)fiber is one of the most widely used thermoplastic fibers in the field of high-temperature filter bags due to the good mechanical properties,outstanding thermal stability and excellent flame retardancy.With the upgrade of flue gas emission standards,the quantity demand and replacement of PPS filter bags both greatly increases.However,most of waste PPS filter bags are disposed by incineration or landfill.A large quantity of smoke,acid or alkaline gas and carcinogens can be produced during the incineration process.Meanwhile,the dust particles,acid and alkaline substances and carcinogens contained in the waste PPS filter bags can also cause pollution of soil and groundwater through the landfill.Therefore,these two traditional treatment methods not only waste resources but also cause serious damage on the environment.Moreover,the most important thing is that PPS fibers cannot be recycled.Therefore,it is of great social significance and economic value to recycle waste PPS fibers and filter bags.Progress In order to promote the efficient and high-value recycling of waste PPS fibers and filter bags,a detailed overview on the current research advances was carried in this study,where the methods,processes,advantages and disadvantages of recycling PPS fibers were compared,analyzed and summarized.The technical difficulties affecting the recycling use of waste PPS filter bags were also analyzed from the aspects of deashing treatment,complex fiber composition and high recycling cost.Finally,a tripartite linkage mechanism of PPS filter bags manufacturer,user and recycling enterprise was proposed to manage and recycle waste PPS filter bags in differe
