The invention discloses a swage discharging
system of a fish
aquaculture pond. The swage discharging
system of the fish
aquaculture pond comprises a bait table, a
sewage collection groove, a swage suction
system composed of an immersible pump and a
water delivery pipe, a
water delivery square groove and a swage settlement pond arranged at the geng (a low
bank of earth between fields) of the
aquaculture pond; the bait table is a long-strip shaped platform, the bait table extends into the pond, and the far off-
bank end of the bait table is provided with a bait feeding
machine; the
sewage collection groove is located right ahead of the bait table, the lower portion of the
sewage collection groove is embedded into the bottom of the pond, the immersible pump is installed in the sewage collection groove, an outlet of the immersible pump is connected with a
water delivery pipe, a water outlet of the water delivery
pipe extends into the water delivery square groove, a water outlet of the water delivery square groove is connected with a water inlet of the swage settlement pond, the swage settlement pond is provided with an upper lid, the upper portion of the swage settlement pond is provided with a clear water overflow opening, the bottom end of the swage settlement pond is provided with a clean pond sewage draining hole, and a swage draining pipe is arranged in the clean pond sewage draining hole. According to the swage discharging system of the fish aquaculture pond, redundant bait residue and most fish excreta in the pond can be absorbed, and
eutrophication in the pond is obviously alleviated; meanwhile, the sewage discharging system is low in production cost, and has high application and popularization value.
