摘　　要：污水处理厂传统强化生物除磷(EBPR)工艺常因进水碳源不足导致除磷性能不佳,难以满足日益严格的排放标准。近年来,利用污泥厌氧水解发酵产生额外“内碳源”的侧流EBPR(S2EBPR)工艺因其在低碳源进水条件下仍可取得高效稳定的除磷性能而受到越来越多的关注。归纳总结了S2EBPR工艺的主要构型及其除磷性能的影响因素,梳理了工艺生化反应过程及功能微生物作用机理的研究进展,并在此基础上对未来工艺的重点研究方向提出了展望,以期推动针对该工艺的进一步研究和推广应用,为污水绿色低碳处理与资源化利用提供支撑。Conventional enhanced biological phosphorus(P)removal(EBPR)processes in wastewater treatment plants often experience poor P removal performance due to insufficient influent carbon source,resulting in failure to meet increasingly stringent discharge standards.In recent years,the side-stream enhanced biological P removal(S2EBPR)process,which generates additional"internal carbon sources"through anaerobic sludge hydrolysis and fermentation,has received increasing attention due to its efficient and stable P removal performance even under low influent carbon conditions.Main configurations of the S2EBPR process and the influencing factors of P removal performance were summarized in detail,the research progress about the biochemical reaction and micro mechanism of the process were systematically reviewed.On this basis,prospects of future key research directions of the S2EBPR process were proposed,in order to promote further research and application of this process,and provide support for green and low-carbon wastewater treatment and resource recovery.
