The invention discloses a treatment method for aquaculture wastewater, and belongs to the field of wastewater treatment. The treatment method comprises the following steps: the aquaculture wastewateris treated by grilles, an efficient shallow air flotation device, microbial fuel cell coupled constructed wetland and an oxidation pond sequentially. The wastewater from the oxidation pond is discharged after the standard is reached, and flows back to the efficient shallow air flotation device if the wastewater is substandard. Efficient removal of heavy metal, COD and nitrogen and phosphorus in the aquaculture wastewater can be realized with the treatment method.
