Developing efficient and sustainable pollution control technologies has become a research priority in the context of escalating global environmental pollution. Nano zero-valent iron (nZVI), with its high specific surface area and strong reducing power, demonstrates remarkable performance in pollutant removal. Still, its application is limited by issues such as oxidation, passivation, and particle aggregation. White rot fungi (WRF) possess a unique enzyme system that enables them to degrade a wide range of pollutants effectively, yet they face challenges such as long degradation cycles and low degradation efficiency. Despite the significant role of nZVI in pollutant remediation, most contaminated sites still rely on microbial remediation as a concurrent or ultimate treatment method to achieve remediation goals. The synergistic combination of nZVI and WRF can leverage their respective advantages, thereby enhancing pollution control efficiency. This paper reviews the mechanisms, advantages, and disadvantages of nZVI and WRF in pollution control, lists application examples, and discusses their synergistic application in pollution control, highlighting their potential in pollutant remediation and providing new insights for combined pollutant treatment. However, research on the combined use of nZVI and WRF for pollutant remediation is still relatively scarce, necessitating a deeper understanding of their synergistic potential and further exploration of their cooperative interactions.
在全球环境污染不断升级的背景下，开发高效且可持续的污染控制技术已成为研究重点。纳米零价铁（nZVI）具有高比表面积和强还原能力，在污染物去除方面表现出卓越性能。然而，其应用受到氧化、钝化和颗粒聚集等问题的限制。白腐真菌（WRF）拥有独特的酶系统，使其能够有效降解多种污染物，但它们面临降解周期长和降解效率低等挑战。尽管nZVI在污染物修复中发挥着重要作用，但大多数污染场地仍依赖微生物修复作为同步或最终处理方法来实现修复目标。nZVI与WRF的协同组合可以利用它们各自的优势，从而提高污染控制效率。本文综述了nZVI和WRF在污染控制中的作用机制、优缺点，列举了应用实例，并讨论了它们在污染控制中的协同应用，突出了它们在污染物修复中的潜力，为联合污染物处理提供了新的见解。然而，关于nZVI和WRF联合用于污染物修复的研究仍然相对较少，需要更深入地了解它们的协同潜力，并进一步探索它们的合作相互作用。
