Energy-saving subsurface filtration device for aquaculture tail water

Abstract

The utility model discloses a kind of bottom discharges and filters breeding tail water energy-saving filter device, it is related to aquaculture water treatment technical field, and it includes: sediment tank one, water inlet pipe is connected on it;Sediment tank two, and the upper portion of sediment tank one is communicated by water guide pipe one;Sediment tank three, and the upper portion of sediment tank two is communicated by water guide pipe two, and its upper portion is provided with drain pipe;Multi-stage filter screen, respectively in the upper portion of sediment tank one, sediment tank two and sediment tank three, and located water guide pipe one and water guide pipe two water inlet below;Sewer, connect in the bottom of sediment tank one, sediment tank two and sediment tank three.The utility model is communicated by water guide pipe one and water guide pipe two to connect three sediment tanks from below to above, to realize the flow deposition of breeding tail water from below to above, energy saving and consumption reduction;Meanwhile, by the multi-stage filter screen in the water outlet bucket of three sediment tanks upper portion, the multi-stage filtration to breeding tail water from below to above is realized, effectively improve the filtration efficiency of breeding tail water.
