This study measured seven indicators in the aquaculture water bodies of three tailwater treatment modes. It also calculated the single pollutant pollution index and removal rate of the water bodies. The results showed that there were no significant differences in the water quality indicators among the groups. Among the three water treatment modes compared in this study, the three-pool-two-basin treatment mode had the best effect, followed by the three-level filtration mode, and the bottom discharge mode performed the worst among the two.
