摘要:

投加增氧剂作为一种提升水体溶解氧的重要手段常用于城市水环境的治理与修复, 研发具有缓释效果的增氧材料可使增氧剂在实际工程中更持久、更稳定地发挥作用. 本文梳理了近年来缓释氧材料的制备方法和释氧性能, 综述了投加缓释氧材料对河湖沉积物和上覆水中营养盐等污染物赋存形态与迁移转化的影响及作用机制, 最后对缓释氧材料在河湖水体污染修复中的应用研究提出了展望和建议.

Abstract:

Oxygen-releasing materials are often used in the treatment and restoration of urban waters as an important method to enhance dissolved oxygen. The development of materials with slow-release property can improve the durability and stability of oxygen release in practical engineering. This paper reviews the preparation methods and oxygen release performance of the slow-release oxygen materials reported in recent years. Moreover, the effects and mechanisms of slow-release oxygen materials on the occurrence, migration, and transformation of pollutants such as nutrients in sediments and overlying water of rivers and lakes are reviewed. Finally, prospects and suggestions for the application of slow-release oxygen materials in the remediation of rivers and lakes are proposed.

Key words: slow-release oxygen materials, preparation, sediment-water interface, nutrients
