吸氮除磷材料的研究进展

Research Progress of Nitrogen Absorption and Phosphorus Removal Materials

氮和磷是地表水体中比较受关注的两种污染物,生活污水过量排入河湖等地表水体中,将引起水体富营养化。着重阐述了改性后的矿物型和非矿物型材料在吸氮除磷方面的研究进展,在此基础上,对其在水处理领域的应用前景进行了展望,认为结合现代先进的化学技术对环境友好型材料进行改性,开发高效的环境友好型材料,对于同步去除水体中氮磷具有重要意义。

Nitrogen and phosphorus are two pollutants of more concern in surface water bodies.Excessive discharge of domestic sewage into rivers and lakes and other surface water bodies will cause eutrophication of water bodies.This paper focused on the research progress of modified mineral and non-mineral materials in nitrogen absorption and phosphorus removal,and on this basis,prospected for its application in the field of water treatment.It is believed that the modification of environment-friendly materials combined with modern advanced chemical technology and the development of efficient environment-friendly materials are of great significance for the simultaneous removal of nitrogen and phosphorus from water bodies.
