The invention relates to the technical field of sewage treatment, in particular to an aquaculture pollutant end treatment method which comprises the following steps: S1, enabling aquaculture tail water discharged from an aquaculture tank to sequentially pass through an ecological ditch where emergent aquatic plants are planted and a sedimentation tank so as to intercept solids with relatively large particles; s2, the water outlet end of the sedimentation tank sequentially passes through a low-oxygen pond where floating-leaved plants are planted, a surface flow wetland and a first-stage oxidation pond, in addition, a novel wetland technology of synergistic removal of conventional and antibiotics is adopted, and the device is small in occupied area, low in cost, easy and convenient to operate and good in treatment effect; the treatment effect on conventional and antibiotic type novel pollutants in the aquaculture tail water is remarkable, the pollution load of the aquaculture tail water on the surrounding water
