摘　　要：聚乙烯醇(PVA)是一种难被生物降解的水溶性高分子有机物,近年来,由于其良好的性能被广泛应用于纺织、食品和医药等行业,但含PVA废水一旦排入水体会造成严重的环境问题,因此有效去除PVA等难被生物降解物质对保护生态环境具有重要意义。本文介绍了含PVA废水的水质特征及处理方法,围绕Fenton法衍生工艺处理含PVA废水的原理及处理效果等内容进行综述分析,对比分析了不同处理方法处理PVA的效果与技术比较,并对Fenton法衍生工艺处理含PVA废水应用前景及发展趋势进行了展望。Polyvinyl alcohol(PVA)is a kind of water-soluble polymer organic matter which is difficult to be biodegraded.In recent years,it has been widely used in textile,food,medicine and other industries because of its good properties.However,once the wastewater containing PVA is discharged into water,it will cause serious environmental problems.Therefore,it is of great significance to effectively remove biodegradable substances such as PVA to protect the ecological environment.In this paper,the water quality characteristics and treatment methods of PVA-containing wastewater were introduced,and the principles and treatment effects of PVA-containing wastewater treatment by Fenton derivative process were summarized and analyzed.The effects and technical comparisons of different treatment methods were compared,and the application prospect and development trend of PVA-containing wastewater treatment by Fenton derivative process were prospected.
