The study established an integrated view to evaluate the effect of exogenous organic carbon (EOC) on removal rate of cefradine and amoxicillin by Microcystis aeruginosa. Meanwhile, the toxicity control assessment of effluents was also investigated on the rotifer (Brachionus calyciflorus) during the algal treatment. The results indicated that glucose and NaAc could be consumed as EOC which enhanced the treatment efficiency of cefradine from 27.11% to 85.19% and amoxicillin from 14.70% to 58.20%, while the toxicity of the reaction products could be controlled at a similar level as the antibiotic itself. Moreover the algal treatment and nutrition regulation could also be applied for artificial wastewater and significantly promote the removal rate with respective increases of 47.04% and 48.75% for cefradine and amoxicillin, respectively. [Display omitted] •EOC was applied as artificial assist for algal antibiotic treatment.•EOC improved triple in the algal efficiency on two antibiotics.•The correlation between added EOC dosage and enhanced efficiency was nonlinear.•The algal and EOC could be applied for artificial wastewater and in larger scale.
