Urban flooding and stormwater runoff have become major challenges in rapidly urbanizing cities, particularly under the influence of climate change and extreme rainfall events. Stormwater generated during urban floods often contains a wide range of contaminants, including pharmaceuticals, and other persistent organic pollutants that threaten aquatic ecosystems and public health. These pollutants in stormwater runoff end up in local streams, lakes, rivers, and even the ocean, where they can harm wildlife and degrade the health of these water bodies. Conventional treatment methods are often insufficient for removing these micropollutants, especially in decentralized or emergency water management systems. Advanced oxidation processes(AOPs) have therefore attracted attention for their ability to degrade recalcitrant organic contaminants through the generation of highly reactive radical species. Various oxidants, including peroxymonosulfate(PMS), peroxydisulfate(PDS), ozone, and periodate(PI) can be activated to produce reactive oxygen species capable of efficiently degrading organic pollutants. However, the conventional homogeneous AOP systems utilizing water-soluble chemical reagents are often limited by environmental release of unreacted chemicals, narrow pH operating ranges, and continuous chemical dosing or energy demand, which restrict their practical application in large scale stormwater management. In this context, single atom catalysts(SACs) as emerging materials for oxidant activators in heterogeneous AOPs provide an alternative due to their high catalytic activity, efficient metal utilization, and structural stability. SACs-based AOP systems can effectively activate oxidants such as PMS, PDS, ozone, and PI to generate reactive species for rapid pollutant degradation. In addition, the heterogeneous nature of SACs enables easy separation and reuse, making them particularly suitable for decentralized treatment systems integrated with urban stormwater infrastructure. These features make SACs-based AOP systems suited for integration into decentralized, technology enabled water treatment in disaster response. This approach supports safe and reliable stormwater management, contributing to improved protection of public health and conservation of ecosystems in flood affected areas.
