Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0023] Please refer to Figures 1-4 , the present utility model provides a technical solution: a device for rapid plant growth and synergistic deep denitrification, including a plant planting plate 1, a wire mesh column 2, a disassembly and assembly component, a plant body 3, a carrier packing 4, a bacterial house 5, and a fixing component.

An disassembly and assembly component for disassembling and assembling the wire mesh columns 2 is arranged between the upper ends of the wire mesh columns 2 and the plant planting plate 1. A plant body 3 is arranged at the upper part inside the wire mesh columns 2 and on the top of the plant planting plate 1. A carrier packing 4 is arranged inside the wire mesh columns 2. A bacterial house 5 is arranged at the corresponding position at the bottom of the wire mesh columns 2. A fixing component for fixing the bacterial house 5 is arranged between the bacterial house 5 and the bottom end of the wire mesh columns 2.

[0025] Among them, the plant planting board 1 is made of lightweight materials with a low density and good buoyancy, which can bear the gravity of the plants and make them float on the water surface; the plant body 3 generally selects plants that can be cultivated in water and have relatively developed roots, such as Hydrocotyle vulgaris, Mentha haplocalyx, Epipremnum aureum, Chlorophytum comosum, etc.; the inside of the wire mesh column 2 is hollow, and the wire mesh column 2 is a porous mesh structure, which is used to fix the carrier filler 4 and provide an environment for the growth of plant roots; the carrier filler 4 is a porous structure, such as ceramsite, etc. The plant roots grow along the filler gaps, and the pore diameter is loaded with microbial strains, which are used to enrich and purify nutrients such as nitrogen and phosphorus in the water. At the same time, it provides the nutrients required for the growth of plant roots. The carrier filler 4 can also provide a growth environment for phytoplankton in the water, and use the photosynthesis of phytoplankton to increase the dissolved oxygen in the water, providing favorable conditions for nitrifying bacteria; the bacterial house 5 is a porous structure with a relatively large density, which can not only carry microorganisms, but also provide a certain gravity for the carrier filler 4 to ensure that it stays in the water body.

[0026] Specifically, through the combined use of the plant planting board 1, the wire mesh column 2, the plant body 3, the carrier filler 4 and the bacterial house 5, trace elements such as nitrogen and phosphorus in the water body can be enriched, providing nutrients for plant growth. The plant rhizomes grow along the ceramsite column due to their tropism for fertilizer, ensuring the rapid growth of plant roots and increasing the purification effect.

[0027] Furthermore, the specific implementation steps are as follows:

[0028] Step 1: In order to achieve the rapid expansion of plant roots, the carrier filler 4 can be pre-loaded with microbial strains. The carrier filler 4 is placed in a solution with a microbial strain content of 1%, and aeration treatment is carried out. After 2-3 days, the microbial strains can be successfully loaded. The carrier filler 4 loaded with microbial strains is filled into the wire mesh column 2, and the process of loading microbial strains is completed.

[0029] Step 2: Plant the plant body 3 on the top of the plant planting board 1, and connect its rhizome position to the wire mesh column 2 so that its rhizome grows along the carrier.

[0030] Step 3: Connect the bacterial house 5 to the lower end of the wire mesh column 2, and its length is deepest to the bottom of the pool.

[0031] Step 4: When the plant body 3 is in the initial growth stage, the water should be slowly introduced to ensure the firmness of the microbial strain loading on the carrier filler 4 and the doubling of the microbial strains. After ensuring that the nitrogen, phosphorus and other pollutants in the effluent meet the standards, the water inlet rate can be slowly increased. After the plant roots are developed, the purification of the water body can be achieved.
