[0001] The utility model relates to the technical field of river and lake water body treatment, in particular to an emergent plant planting platform for slightly polluted water bodies. Background Art

[0002] Since the release of the "Ten Water Regulations" in 2015, through a series of measures such as intercepting pollution and controlling sources, non-point source treatment, internal source control, returning fisheries to lakes, and ecological restoration, remarkable results have been achieved in rivers and lakes with high pollution loads across the country. In particular, the eutrophication level of lakes has been greatly reduced, basically at Class III-IV surface water, which is a slightly polluted water body.

[0003] For the slightly polluted water bodies in the rivers and lakes whose water quality has improved significantly, if we want to further improve the water quality in the deep water areas (water depth greater than 3m) and improve the ecological environment through plant planting, there are the following problems:

[0004] (1) Deep water areas are not conducive to the recovery of submerged plant communities;

[0005] (2) The emergent plants planted on ordinary ecological floating trays grow poorly and cannot play their role in ecological water purification;

[0006] (3) Aquatic animals gnaw on the roots of emergent plants, causing plant death, which is not conducive to the recovery of a healthy aquatic ecosystem.

[0007] Based on the technical defects in the treatment of deep water areas of the above-mentioned micro-polluted water bodies (surface water Class III-IV), it is necessary to design a plant planting platform based on micro-polluted water bodies to solve the above-mentioned problems and accelerate the process of further improving the water quality.

[0029] The bottom of the planting pot 2 is provided with a plurality of holes. A planting matrix is ​​provided in the planting pot 2, and emergent plants 5 are planted in the planting matrix. The planting matrix includes a gravel layer 6 and a filler layer 7 which are alternately arranged from bottom to top.

[0030] Through the above-mentioned method, the micro-polluted water body emergent plant planting platform provided by the utility model can establish a planting platform that is not affected by water depth, wind and waves, etc. in the deep water area of ​​the micro-polluted water body, which is conducive to the restoration of the diversity of the water body ecosystem. On this basis, the gravel layer 6 and the filler layer 7 are alternately arranged from bottom to top in the planting pot 2, which can not only provide the required nutrients for the root system of the emergent plant 5, but also promote the root growth of the emergent plant 5; at the same time, the protective screen 3 arranged at the bottom of the floating platform can effectively protect the root system of the emergent plant 5 to prevent it from being eaten by fish, and give full play to the ecological functions of the plant root system and the emergent plant 5 itself, so as to further improve the water quality of the micro-polluted water body while promoting the normal growth of the emergent plant.

[0031] More specifically, in some embodiments of the present invention, the floating platform includes a plurality of floating bodies 1, and adjacent floating bodies 1 are detachably connected to facilitate assembly and disassembly and convenient application.
