摘要
由于污泥中含有富含氮、磷的有机化合物以及重金属等微量元素和病原体等无机物质,被广泛制备成吸附剂。污泥基吸附剂被广泛用于去除水和废水系统中的各种污染物,对污泥的结构和活化机理进行说明,探讨了污泥的物理、化学等活化改性方法,介绍了近些年来污泥基吸附剂在水处理方面的一些研究与应用进展。同时,对污泥基吸附剂研究面临的挑战和未来的研究方向进行了探讨。
Because sludge contains organic compounds rich in nitrogen and phosphorus as well as inorganic substances such as trace elements and pathogens such as heavy metals,it is widely prepared as an adsorbent. Sludge-based adsorbents are widely used to remove various pollutants from water and wastewater systems. The structure and activation mechanism of sludge are explained,physical and chemical activation modification methods of sludge are discussed,and some research and application progress of sludge-based adsorbents in water treatment in recent years are introduced.At the same time,the challenges faced by sludge-based adsorbent research and the future research directions are discussed.
