Carbon source limitation is a critical factor restricting the treatment efficiency of domestic wastewater by algae–bacteria consortia. Using agricultural waste as an external carbon to enhance purification performance holds significant potential. This study investigated effects peanut shell powder (PSP) on in The results demonstrated that optimal PSP dosage (2 mg/L) improved removal efficiencies TN, TP, and COD 29.6%, 40.9%, 18.7%, respectively. In contrast, excessive reduced performance. primary mechanism which influenced consortia involved changes microbial biomass community structure. An promoted proliferation dominant algal species, Chlorella, enhanced photosynthetic activity, increased relative abundance Rhodanobacter, known for its effective degradation benzene compounds. Conversely, caused cell rupture, inhibited Chlorella growth photosynthesis, elevated Microcystis Brevundimonas, pose health risks. conclusion, can improve effluent quality safety consortia, represents green, economical pathway optimizing processes.
