The ecological blanket 2 at the top of the spur dike is provided with planting density of 45 plants/m 2 The middle part of the emergent aquatic plants 1 such as iris, cattail, calamus, loosestrife and the like is sequentially provided with a mixed adsorption layer 3 of green zeolite and coal cinder and a ceramsite denitrification layer 4 from top to bottom, and the bottom part is provided with a gravel layer 5. Wherein the particle size of the green zeolite and the coal cinder is 5-10mm, the particle size of the ceramsite is 5-8mm, and the particle size of the gravel is 10-15 cm. Microorganisms are attached to the surfaces and the inner pores of the green zeolite, the coal cinder, the ceramsite and the gravel, so that the eutrophic elements such as N, P in the water body can be effectively removed under the synergistic action of the plant-filler-microorganisms. Emergent aquatic plants 1 planted on the ecological blanket 2 can absorb nitrogen and phosphorus in water through root systems, have a certain landscape effect and are beneficial to the restoration of an ecological system. The mixed adsorption layer 3 of the coal cinder and the green zeolite is mainly used for adsorbing nitrogen and phosphorus in a water body and converting ammonia nitrogen into nitrate substances for plant growth under the action of aerobic nitrobacteria. The ceramsite denitrification layer 4 mainly converts nitrate in water into nitrogen under the action of anaerobic denitrifying bacteria, so that nitrogen in the water is thoroughly removed; (3) finally, river water passes through a deep pool 7 on the other side river bank 9, the distance between the center of the deep pool 7 and the center of the spur dike can be 0.2-0.8 times of the width of the river channel, the deep pool 7 is 25-40cm lower than the river bottom, and the planting density in the deep pool 7 is 30 plants/m 2 The submerged plants 8 such as tape grass, hornwort, watermifoil and the like. River water enters the deep pool 7, the longitudinal structure of the water flow is changed, the flow rate is reduced, and under the action of the submerged plants 8, the water in the water can be further removedSuspended substances and nutrient substances provide a good habitat environment for the survival and the propagation of fishes and other aquatic animals and plants, and are favorable for the restoration of an ecological system.
