摘　　要：针对聚丙烯酰胺的大量使用会造成污水中含聚物含量升高,水体黏度增大,对环境具有潜在威胁的问题,寻找有效降解聚丙烯酰胺的方法。阐述分析了聚丙烯酰胺物理降解和化学降解的研究状况及降解机理,并对降解研究的发展趋势进行了展望:关于污水中残留的聚丙烯酰胺降解问题,今后的研究工作应该借鉴难降解有机物的方法,优化工艺条件,深入研究降解机理,同时应加快含聚污水联用降解设备的研制。Extensive use of polyacrylamide can lead to increase of content of polymer and viscosity of effluent-waste water, causing as a result a potential threat to environment. Therefore, exploration of an effective method for degradation of polyacrylamide has become nowadays a hot point of study. Following an analysis and description of the state-of-the-art of the work on physical and chemical degradation methods currently applied as well as the degradation mechanism of each method, the paper looks ahead to the developing trend of the research work in this respect. It is pointed out that the work in the future should be directed toward adoption of intensified degradation process through combined use of multiple degradation methods applied in different industrial sectors, optimization of process conditions, making intensive study of degradation mechanisms, and accelerating development of equipment for treating polyacrylamide-containing effluent using integrated degradation methods.
