Wherein, the plants 13 mainly comprise three types of adsorption climbing plants, winding climbing plants and hanging plants. The adsorption climbing type plant is that the plant 13 is provided with a sucker with adsorption capacity on the stem, mucus can be secreted in a certain growth period, the plant 13 and an attached object are firmly combined together, a traction facility is not needed, the technical requirement is not high, only the growth requirement of the plant 13 is met in the use process, and the coverage rate of the plant 13 is high; the adsorption climbing type greening is suitable for the upstream surface of the river section revetment, and has low requirements on water flow scouring and erosion strength. The winding climbing type plant means that the plant 13 climbs and hooks on the surface of an object by means of tendrils and barbs grown by the plant 13, or winds the object by utilizing the stem of the plant to enable the plant to grow upwards, the stem is called as a winding stem, the winding climbing type plant can form an ideal vertical greening effect by drawing the plant 13 through materials such as a metal framework, a rope, a wooden frame and the like, and a support frame for winding the plant is generally installed during use; the winding and climbing type greening is suitable for the upstream surface of the river segment revetment, and has low requirements on water flow scouring and erosion strength. The hanging type plants are planted on the tops of the banks, and by utilizing the characteristics of climbing and nodding, the hanging type plants are not greatly influenced by water flow and water level changes, are not influenced by wall materials, height and other factors, and are suitable for the upstream surfaces of the banks of any conditional river segments; the purposes of removing pollutants, nitrogen and phosphorus and restoring the habitat are achieved by utilizing the types of different plants 13 in the hanging basket panel and the difference of functions of microbial communities. In specific use, the three types of plants 13 can be planted, and the three types of plants 13 are all planted at intervals as shown in figure 1.

In addition, the average length of the plant 13 is 0.4-1.2m, and the planting density is 25-35 plants per square meter. The plants 13 need to be normally operated, maintained and managed, the plant 13 residues are timely cleaned, and the planting groove 11 is ensured to be smooth.

The above-mentioned plants 13 are generally planted for 2 years or more and are trimmed once a year. Cleaning aged branches of the vine 13, enabling other plants with few branches and leaves to grow on vain branches by pinching or pruning parts, and enabling weak-growing or diseased plants to promote new branches to germinate by re-shearing; the leaf-viewing plants 13 are all cut and pinched by light shearing, and the color blocks of the plants 13 after the shearing are smooth and have no obvious concave-convex feeling. Meanwhile, the plants 13 need to be reseeded regularly, and for various reseeded plants 13, watering should be carried out in time, and normally maintaining needs to be carried out after the plants are watered thoroughly for three times and root fixing water is added.

As shown in fig. 1, the plants 13 in the hanging part 1 have the following ways for removing ammonia nitrogen: firstly, the adsorption function of a water purification matrix is realized, the water purification mixed matrix 12 such as zeolite, ceramsite and the like is added into the water purification matrix, and the water purification matrix has a good adsorption function due to the special framework composition and the self electrostatic action of the water purification mixed matrix. The zeolite particles have developed pore canals and a hollow framework structure, the volume of crystal cavities can reach 40-50% of the volume of the zeolite particles, and the specific surface area can reach 400-1000m²And/g, providing multiple active sites for adsorption. The unique crystal structure of the molecular sieve enables the molecular sieve to have a large number of uniform micropores, the pore diameter is mostly within 0.3-10nm, and the uniform micropores are equivalent to the size of molecules, so that the selective adsorption characteristic of the molecular sieve is formed. Then gradually transforming through the nitrification and denitrification of microorganisms, simultaneously, the plant 13 root cells absorb and utilize nitrogen in the form of ammonium salt and nitrate to promote the growth of the plant 13, and finally leading the nitrogen to be generated through the synergistic action of the substrate of the three-dimensional ecological cradle system, the plant 13 and the microorganismsThe contaminants are removed from the body of water.

The plants 13 in the suspension unit 1 have several routes for total phosphorus removal: the phosphorus removal effect of the mixed substrate 12 is the primary way for system phosphorus removal, the surface charge and the surface potential have electrostatic adsorption effect, and phosphate with negative charge in water is adsorbed by the attraction effect of the positive charge on the surface of the substrate. The mixed substrate 12 of water purification substrates such as ceramsite, oyster shell and the like is rich in Ca²⁺、Mg²⁺、Fe³⁺And Al³⁺And the active ingredients are easy to combine with phosphate to form a colloidal complex and precipitate on the surface, so that the active ingredients are fixed and removed.

The following examples illustrate:

the mixed matrix 12 mainly comprises soil, peat soil, ceramsite, zeolite and oyster shell, the proportion ratio of the soil, peat soil, ceramsite, zeolite and oyster shell is 1:1:0.5:0.5:0.5, and the plants 13 cultured by the mixed matrix 12 purify the river channel.

NH collected at the water inlet (i.e. the position where the plant 13 is hung without the hanging part 1 is used as an inlet) is collected by collecting river water in the river channel₄ ⁺NH collected at the outflowing water (i.e. the water flow along the river with the plants 13 hanging to the place without hanging plants 13 as outlet) with N concentration between 0.6 and 2.68mg/L₄ ⁺NH of purified river water with N concentration of 0.32-1.65mg/L₄ ⁺N concentration has reached surface water class V standard, for NH₄ ⁺The average removal of-N was 34.7%.

By collecting river water in the river channel, the concentration of TP collected at a water inlet position (namely, the position where the plant 13 is not hung on the hanging part 1 is used as an inlet) is 0.24-0.62mg/L, the concentration of TP collected at a water outlet position (namely, the position where the water flow flows along the river channel where the plant 13 is hung to the position where the plant 13 is not hung is used as an outlet) is 0.11-0.41mg/L, the concentration of TP of the purified river water basically reaches the standard of surface water class V, and the average removal rate of TP can reach 40%.

In conclusion, the river channel purification device provided by the disclosure realizes removal of nitrogen and phosphorus in river water and circulation purification of the river water by utilizing the synergistic effect of the mixed matrix 12, the plants 13 and the microorganisms of the three-dimensional suspension component 1, meets the flood control requirement, and effectively solves the problem of river landscape function loss caused by the vertical hard revetment 100 with narrow space in the watershed shore and the stone-masonry hard revetment 100.
