Aquaculture pond facilitating sewage discharge

The utility model relates to a device for aquaculture, particularly to an aquaculture pond facilitating sewage discharge. The aquaculture pond facilitating the sewage discharge comprises a pot-shaped sewage discharge device bottom, a water return port arranged in the center of the sewage discharge device bottom and a spirally-downward sewage discharge exit arranged on the side surface of the sewage discharge device bottom, and the upper end of the water return port is provided with a sewage discharge device cover. Due to the fact that the water return port is arranged in the center of the sewage discharge device bottom and the spirally-downward sewage discharge exit is arranged on the side surface of the sewage discharge device bottom, the aquaculture pond facilitating the sewage discharge can effectively separate returned water from sewage effectively and facilitate the sewage discharge when water in the aquaculture pond flows in a swirling mode.
