摘要

摘要: 结合蓝藻资源化利用背景，通过利用蓝藻为原料制备的蓝藻基生物质复合碳源（蓝藻基复合碳源），系统分析其在活性污泥脱氮除磷中的应用效果及碳减排潜力。结果表明：与使用传统乙酸钠碳源的污泥相比，以蓝藻基复合碳源驯化的活性污泥展现出良好的脱氮除磷效果，Zeta电位绝对值维持在更低水平（最高为3.8 mV），污泥絮体结合更紧密，结构更稳定。蓝藻基复合碳源的投加显著改变了污泥的微生物群落结构，促进了功能菌属（如Saccharimonadales、Defluviicoccus、Nakamurella）的富集，推动有机物与氮、磷等营养物质的协同代谢，在强化菌群结构稳定性的同时，提升了污泥的絮凝沉降性能。碳排放核算表明，相较于乙酸钠，蓝藻基复合碳源可减少约77%的碳排放。研究为蓝藻水华污染治理与污水厂低碳运行的协同推进提供了切实可行的技术方案与科学依据。

Abstract: At present， the situation of cyanobacterial blooms in China remains severe. Meanwhile， the utilization of traditional fossil-based carbon sources increases both the operating cost and the carbon emission burden of wastewater treatment processes. Focusing on the resource utilization of cyanobacteria， this study employed a novel cyanobacteria-based composite biomass carbon source （i.e.， cyanobacteria-based composite carbon source） and systematically analyzed its application performance in nitrogen and phosphorus removal by activated sludge， as well as its potential for carbon emission reduction. The results showed that， compared with the activated sludge acclimated with a conventional sodium acetate carbon source， the activated sludge acclimated with the cyanobacteria-based composite carbon source exhibited excellent nitrogen and phosphorus removal efficiency， and the absolute value of the Zeta potential was maintained at a lower level （up to 3.8 mV）. The sludge floc structure was more compact and stable. The addition of the cyanobacteria-based composite carbon source significantly altered the microbial community structure of the sludge and promoted the enrichment of functional genera （e.g.， Saccharimonadales， Defluviicoccus， Nakamurella）， thereby facilitating the synergistic metabolism of organic matter and nutrients （nitrogen and phosphorus）. The flocculation and sedimentation performance of the sludge was also enhanced， and the stability of the microbial community structure was strengthened. The carbon emission accounting indicated that， compared with sodium acetate， the cyanobacteria-based composite carbon source could reduce the carbon emissions by approximately 77%. This study provides a practical technical solution and a scientific basis for advancing the control of cyanobacterial blooms and the low-carbon operation of wastewater treatment plants.
