Land-based round pool bottom sewage discharge assisting device

The utility model discloses a land-based round pool bottom sewage discharge aiding device, which belongs to the technical field of aquaculture, solves the technical problem of muddy water in a round pool, and comprises a separation net which is positioned in the round pool and divides the round pool into an upper part and a lower part, a culture area positioned above the separation net, and a sewage discharge area positioned below the separation net, a sewage settling device is arranged in the sewage discharging area, a plurality of grids defined by conductive plates are arranged in the sewage settling device, and the conductive plates are electrically connected with the positive electrode of the low-voltage power supply. According to the utility model, the flowing speed of flowing water on the current-conducting plate is slowed down after being blocked by the grids, and suspended particles in the water are precipitated; meanwhile, as the suspended particles are generally negatively charged, stable colloid is
