Multi-functional aquacultural biological floating island water purification device

Abstract

The invention relates to a water purification device for aquaculture, in particular to a multi-functional aquacultural biological floating island water purification device. An arc-shaped canopy (12) covers on the top of a cylindrical drum body (3); the drum body (3) is supported by a frame (1) and respectively provided with an A-shaped stainless steel net (2), a floating filter material layer (4), a B-shaped stainless steel net (6), a foam grain filter material (8), a C-shaped stainless steel net (13) and a heavy filter material (9) from bottom to top; a plurality of baffle rings (10) are configured in a heavy filter material (9) layer and uniformly and radially provided with water diversion channels (11) comprising water diversion weirs; the drum body (3) is internally provide with a water pumping pipe (5); a water outlet positioned on the upper part of the water pumping pipe (5) is positioned on the upper part of the heavy filter material (9) layer, a water inlet positioned on the lower end of the water pumping pipe (5) is connected with an air-water chamber (15) and a horizontal water inlet pipe (14); a pressure air pipe (16) is connected to the bottom of the air-water chamber (15); and aquatic plants are planted on the heavy filter material (9) layer. In the invention, an upper water layer and a lower water layer are exchanged by utilizing a water pumping technology, the dissolved oxygen of the water layers of a water body is provided and the water body is treated by utilizing the aquatic plants and various filter material components, thereby the treatment area of the water body is increased ; and in addition, the invention has little energy consumption.

Description

[0001] technical field [0002] The invention relates to an aquaculture water purification device, in particular to an aquaculture water purification device adopting a biological floating island structure. Background technique [0003] In recent years, in order to obtain more economic benefits, pond farmers have mostly adopted the mode of high-density stocking and large-scale fertilization and feeding, resulting in a large accumulation of residual bait and fish excrement in the water body, and a sharp increase in the content of organic matter, nitrogen, and phosphorus in the water. seriously polluted the water quality. Because of this, aquatic plant purification devices have also begun to be applied to pond aquaculture systems to remove nitrogen, phosphorus, organic matter and other pollution in aquaculture water through absorption and adsorption of plant roots and nutrient competition among species. With the development of technology, the biological filter material used ...

Problems solved by technology

This device utilizes comprehensive technologies such as plants and biological filter materials to treat water quality, but it still has the following disadvantages: 1. The energy consumed by the micro-lift water lifting device is large, and the device can only lift the water body at the bottom of the floating bed , the purified water only flows to the bottom of the floating bed in the end, and cannot form a circulation in th
