纳米零价铁在水体富营养化治理中的应用

The Use of Nanoscale Zero-Valent Iron for the Remediation of Water Body Eutrophication

水体富营养化现象不仅威胁着水生态系统的平衡,还对人类健康、经济发展构成了严重挑战,工业废水和生活污水中的营养物质通过城市排水系统进入水体,增加了水体中的氮、磷等营养物质浓度,导致富营养化问题日益严重。纳米零价铁在水体富营养化中的应用潜力得到了广泛关注。文章评述了纳米零价铁在水体富营养化治理中的应用。首先指出了水体富营养化现象对生态系统和人类健康的威胁,随后介绍了纳米零价铁的制备方法和表征技术,以及其在水体治理中的独特优势和局限性,呼吁进一步加强相关研究以解决这些问题。最后进一步探讨未来展望和发展趋势,通过不断创新和技术提升,纳米零价铁有望为改善水体生态环境、保障人类健康和促进社会经济发展做出更为显著的贡献,推动水体富营养化治理技术向着更加高效、可持续的方向发展。文章以期为纳米材料在水体富营养化中的应用研究提供相关参考。 The phenomenon of water body eutrophication not only threatens the balance of aquatic ecosystems, but also poses serious challenges to human health and economic development. Nutrients in industrial wastewater and domestic sewage enter water bodies through urban drainage systems, increasing the concentration of nutrients such as nitrogen and phosphorus in water bodies, leading to increasingly serious eutrophication problems. The potential application of nanoscale zero-valent iron in water body eutrophication has received widespread attention. This article reviews the application of nanoscale zero-valent iron in water body eutrophication treatment. Firstly, the threat of water body eutrophication to ecosystems and human health was pointed out. Then, the preparation methods and characterization techniques of nanoscale zero-valent iron were introduced, as well as their unique advantages and limitations in water treatment. It was called for further strengthening of relevant research to address these issues. Finally, we will further explore future prospects and development trends. Through continuous innovation and technological advancement, nanoscale zero-valent iron is expected to make more significant contributions to improving the ecological environment of water bodies, ensuring human health, and promoting socio-economic development. This will promote the development of water body eutrophication treatment technology towards a more efficient and sustainable direction. This article aims to provide relevant references for the application research of nanomaterials in water body eutrophication.
