摘要

摘要: 针对低碳源城市污水磷去除效率受限的关键难题，侧流强化生物除磷工艺（S2EBPR）作为创新解决方案受到广泛关注。近年来的研究发现聚磷菌（PAOs）的代谢特性是磷去除的关键所在。传统强化生物除磷（EBPR）工艺在低C/P条件下存在明显局限，因碳源不足导致PAOs竞争力不足，直接制约除磷效能。S2EBPR则通过构建独立侧流污泥发酵单元（SSSF），精准调控厌氧发酵条件，增强PAOs在碳源竞争中的优势地位，有效实现了PAOs的富集与代谢效能提升，不仅突破了低C/P限制，更凸显出侧流强化除磷的核心优势。进一步探讨了影响S2EBPR效能的关键操作与环境参数，可为工艺精准调控提供依据。此外，通过阐述S2EBPR与新兴水处理技术的集成应用进展，可为污水处理的高效同步脱氮除磷以及资源化回收利用提供理论支撑和技术参考。

Abstract: The challenge of limited phosphorus removal efficiency in low-carbon municipal wastewater is addressed by the innovative side-stream enhanced biological phosphorus removal （S2EBPR） process，which has garnered significant attention. Recent research highlights the core mechanism rooted in the metabolic traits of phosphorus accumulating organisms （PAOs）， pivotal for effective phosphorus removal. However， conventional enhanced biological phosphorus removal （EBPR） processes face constraints under low C/P conditions， where the scarcity of carbon source weakens PAOs’ competitive edge， directly impeding phosphorus removal efficiency. Consequently， S2EBPR establishes a side-stream sludge fermentation unit， through which anaerobic fermentation conditions are precisely regulated and PAOs’ dominant position in carbon source competition is strengthened， thereby enhancing the enrichment of PAOs and the optimization of their metabolism. This breakthrough not only overcomes the low C/P limitation but also underscores the fundamental advantage of S2EBPR. Furthermore， the discussion delves into the critical operational and environmental parameters influencing its efficacy， offering a foundation for precise process management. Looking ahead， the synergistic development of S2EBPR alongside emerging water treatment technologies holds promise for simultaneously efficient nitrogen and phosphorus removal in wastewater treatment， thereby furnishing technical insights for fostering sustainable resource recycling practices.
