[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] See also Figure 1-3 , the utility model provides a technical solution:

[0019] Embodiment 1:

[0020] like Figure 1-3As shown, a device for treating aquaculture wastewater comprises a treatment barrel 1, the top of the treatment barrel 1 is connected to a water inlet pipe 2 for replenishing aquaculture wastewater, the bottom of the treatment barrel 1 is connected to a water outlet pipe 3 for discharging treated wastewater, the top of the treatment barrel 1 is fixedly connected to a liquid storage tank 4 for storing flocculant, the bottom of the liquid storage tank 4 is connected to a discharge port 5 for discharging the flocculant into the treatment barrel 1, the interior of the treatment barrel 1 is provided with a water blocking block 6 for blocking the discharge port 5, and a reciprocating component for driving the water blocking block 6 to move up and down is installed on the treatment barrel 1.
