污水碳捕集工艺文献计量学分析及研究进展OA

Based on the bibliometric analysis,the literature in the field of wastewater carbon capture processes in the Web of Science Core Collection database was visualized and analyzed.The results show that the combination of wastewater carbon capture with anaerobic methanogenesis is a research hotspot in this field.Bioflocculation and related carbon capture processes serve as key pathways for energy recovery from wastewater.High-rate activated sludge(HRAS),chemically enhanced primary treatment(CEPT),and membrane separation are three typical wastewater carbon capture processes.Membrane separation achieves the highest carbon capture efficiency while requiring the highest operational costs.HRAS significantly reduces operational expenses through bioflocculation while exhibiting lower carbon capture efficiency than membrane separation and CEPT.Without the need for an external carbon source,partial nitritation/anammox and partial denitrification/anammox processes are particularly suitable for treating the low C/N ratio effluent from carbon capture units.Future research should investigate the regulation and mechanisms of extracellular polymeric substances in carbon capture,while optimizing synergistic effects among carbon capture processes.
