富铁基质人工湿地在低碳氮比废水处理中的应用研究进展
Research progress on the application of constructed wetlands with iron-rich substrates for low C/N ratio wastewater treatment
摘要
Abstract
Constructed wetlands(CWs)are commonly used as the final treatment stage before discharging effluents from wastewater treatment plants(WWTPs)into natural waters.However,effectively treating carbon-limited but nutrient-enriched effluents remains challenging.Iron-rich substrates offer a promising solution because of their high adsorption capacities,redox activity,and biological affinity.In this study,we review the research directions and hotspots related to the application of iron-rich substrates in CWs,with an emphasis on their performance under low C/N ratio wastewater conditions.We also elucidate the synergistic mechanisms by which iron-rich substrates(i)stimulate microbial coupling of iron and nitrogen cycles for nitrogen removal and(ii)integrate surface adsorption,precipitation,ligand exchange,and co-precipitation for phosphorus removal.Considering the potential issues that may arise during the long-term operation of iron-rich CWs,such as iron passivation,clogging,microbial iron toxicity,and accumulation of denitrification byproducts,this study proposes recommendations for future research in terms of material development,system optimization,and mechanism exploration.These suggestions aim to provide strong support for improving purification efficiency and ensuring the long-term stable operation of CWs treating effluents from WWTPs.关键词
