Embodiment Construction
[0028] The specific embodiments of the present invention will be described below in conjunction with the accompanying drawings.
[0029] The ecological restoration system of small and medium-sized rural rivers in this embodiment, including the floating bed system, can refer to figure 1 , its structure is: comprise buoyant body frame 7, the planting area that is connected on the upper part of buoyant body frame 7, and the suspended packing area that is connected on the lower part of buoyant body frame 7;
[0030] The planting area includes several evenly distributed grid areas, the vertical section of the grid area is a cone-shaped structure with a large upper part and a smaller lower part, the grid area is used to place the planting basket 6 whose shape matches it, and the planting basket 6 is used for planting emergent plants 5; the floating body frame 7 is hollowed out on the surface and has a hollow structure inside, and the planting basket 6 is connected with the floating ...

Abstract
The invention relates to an ecological restoration system for small and medium-sized river channels in rural areas, which comprises a floating bed system which structurally comprises a floating body frame, a field planting area connected to the upper portion of the floating body frame and a suspension filler area connected to the lower portion of the floating body frame. The field planting area comprises a plurality of uniformly distributed grid areas, the longitudinal section of each grid area is of a big-end-up conical structure, the grid areas are used for placing field planting baskets matched with the grid areas in shape, and the field planting baskets are used for planting emergent aquatic plants; the floating body frame is of a structure with the hollow surface and the hollow interior, and the field planting basket is communicated with the floating body frame in the vertical direction. The suspension filler area comprises a plurality of suspension ropes tied below the floating body frame, and the suspension ropes are provided with three-dimensional elastic fillers and biofilm culturing biological ropes. The technical problem that the purification effect of a floating bed system is insufficient is solved, the air permeability is enhanced, the air reoxygenation process is facilitated, a larger and more stable space is provided for plant growth, a larger space is provided for microorganism growth, the absorption effect on nitrogen, phosphorus and organic matter is improved, and the deep purification effect is improved.
Description
technical field [0001] The invention relates to the technical field of river restoration, in particular to an ecological restoration system for small and medium-sized rural rivers. Background technique [0002] Nutrients such as nitrogen, phosphorus, and organic matter flow into small and medium-sized rivers in a short period of time, causing algae and plankton to multiply, consuming a large amount of dissolved oxygen in the water, and then forming nutrient-rich water and even black and smelly water, which seriously endangers the water ecosystem and wastes water. water resources. Ecological management technology is considered to be an advantageous technology for the management of small and medium-sized rivers in rural areas. Both ecological floating beds and ecological slope protection are ecological management technologies. The ecological floating bed adopts hydroponic plant technology to degrade nitrogen, phosphorus and organic matter in the water by using the absorption ...
