Abstract

Addressing the challenge of nitrogen-containing wastewater treatment, the photocatalytic-microbial coupled denitrification technology has emerged as a new research hotspot due to its advantages of high efficiency, cost-effectiveness, and environmental friendliness. After a comparative analysis of the advantages and disadvantages of different photocatalytic denitrification technologies, a detailed introduction to the current research status of domestic and international photocatalytic-microbial coupled denitrification processes is provided. The review emphasizes three major forms of the coupled system, including indirect sequential coupling of photocatalytic and microbial, direct coupling, as well as bioelectrochemical-photocatalytic coupling systems. The intrinsic interaction mechanisms within the coupled system are deeply explored, such as the physiological and ecological responses of microorganisms to photocatalysts, the optimization of microbial communities by the photocatalytic process, the migration and transformation mechanisms of photocatalysts within biofilms, and the electron transfer processes between photocatalysts and microorganisms. Finally, the article points out the existing bottlenecks in this technology, such as the development of visible-light materials, the safety of nanomaterials, the long-term stability of the system, and the scaling up for engineering applications. Suggestions are made for deepening the mechanism research, developing new coupled processes, optimizing materials, and promoting engineering applications, with the aim of providing a reference for the efficient and green treatment of nitrogen-containing wastewater.
