Problems solved by technology
However, the current ecological floating bed technology still has the following deficiencies: for example, the ecological floating bed is greatly affected by the water area and the flow velocity of the water. The treatment capacity of the initial rainwater non-point source polluted water body with short residence time is limited
Moreover, the existing floating bed devices for water purification have relatively simple functions. Some floating islands have a simple structure, the absorption and purification effect of plants is limited, and the water depth range of treatment is limited. Water purification effect

Embodiment 1
[0044] Use aged bamboo with an outer diameter of about 10cm, cut into 12 bamboo columns, of which 2m, 1m, and 0.5m are used to make a floating bed frame, and the length, width, and height of the floating bed frame are respectively 2m, 1m, and 0.5m. In addition, two 1m-long bamboos are cut as the lower beams, and the position is 50cm away from the center, according to figure 1 The upper and lower floors of the floating bed are built as shown, and all the joints of the frame are bound and fixed with iron wire or nylon rope; dry bamboo is taken to make a batch of bamboo with specifications of 0.03×2m, 0.03×1m, and 0.03×0.7m respectively piece. then press figure 1 As shown, the horizontal and vertical connections are alternately connected, and the width of the neutral area and the bamboo slices can be configured at a ratio of 1:1. figure 1 As shown, bamboo and bamboo posts are used to make fences for fixing horizontal bamboo sheets and vertical bamboo sheets. The ratio of the ga...

Abstract
The invention belongs to the technical field of ecological environment engineering, and particularly relates to a three-dimensional ecological floating bed suitable for a high-flow-velocity water area. According to the three-dimensional ecological floating bed, the water flow path is changed, the water flow speed is reduced, the retention time of the water flow in the three-dimensional ecological floating bed is prolonged through the fences with the non-parallel fence pieces and the filler, the treatment depth is increased through the design of the three-dimensional floating bed, and the floating bed filler is a porous medium; the porous filler can adsorb pollutants in the water body and provide a habitat environment for microorganisms, and formation of a biological membrane is promoted, so that the purification function of the water body is enhanced.
Description
technical field [0001] The invention belongs to the technical field of ecological environment engineering, and in particular relates to a three-dimensional ecological floating bed suitable for fast-flow waters. Background technique [0002] Ecological floating bed (also known as biological floating bed, biological floating island, artificial floating island, artificial floating bed, etc.) technology is a practical technology that combines water environment governance and water ecological restoration. As the substrate or carrier, the water surface soilless planting technology is adopted with the comprehensive integration of modern agronomic and ecological engineering measures. The function of the ecological floating bed is similar to the plant belt in the water body, which can export the nutrients in the water body through the growth of plants. In addition, a biofilm is formed through the plant root system, and through the microbial decomposition and synthesis metabolism, it ...
