Abstract

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.
