摘　　要：PVA因良好的上浆性能被广泛应用于纺织行业。退浆废水具有成分复杂、有机物含量高、可生化性差等特点,传统的生物处理工艺受到严峻挑战。同时,直接排放PVA废水至受纳水体会对水体造成不利影响。梳理近年来处理PVA退浆废水的有关文献,论述PVA退浆废水的生物降解及资源化研究进展,进一步讨论处理PVA退浆废水的技术难点和未来发展方向,为有效处理不同类型的PVA废水提供参考,以减轻生态环境负荷。Polyvinyl alcohol(PVA)is widely used in the textile industry due to its good size performance.Desizing wastewater has the characteristics of complex components,high organic content and poor biodegrad⁃ability,the traditional biological treatment process has been severely challenged.At the same time,direct dis⁃charge of PVA containing wastewater into the receiving water will cause adverse effects on the water body.The related literatures on desizing wastewater containing PVA treatment were analyzed.The current research status of biological treatment of desizing wastewater containing PVA and its progress in resource research were summarized.The possible problems and future development trends of the wastewater containing PVA treatment process were further discussed,so as to provide reference for effectively treating different types of wastewater containing PVA and reduce the load of ecological environment.
