[0036] The water surface cultivated duckweed in S3 is a floating plant with roots in the water and a floating leaf plant with roots in the riverbed mud. The floating plant with roots in the water can be one or more of water hyacinth, water hyacinth, etc., and the floating leaf plant with roots in the riverbed mud can be one or more of lotus, water turtle, etc.

[0037] When raising fish and shrimp in the water in S4, it is necessary to mix herbivorous, omnivorous and carnivorous fish and shrimp. Climbing snails, clams, and other shellfish and a large number of benthic animals should be raised at the bottom of the water. The ratio of herbivorous, omnivorous and carnivorous fish and shrimp is 6:10:1.

[0038] In S4, aeration is performed to increase oxygen in the water body to promote the growth and reproduction of aerobic bacteria, thereby strengthening and accelerating the decomposition of organic pollutants in the water. A circulating water pump is used in the aeration process.

[0039] In S5, space is left on the river bank for afforestation on both sides, and trees with larger crowns are planted to gradually form a forest belt.

[0040] In S6, weeds, waste, and drifting garbage are removed at the edge of the water area to ensure smooth flow of water, maintain a good water environment, and keep the water surface clean and beautiful.

[0041] Embodiment 2

[0042] A method for improving water quality in water ecological restoration comprises the following steps:

[0043] S1. Sampling and testing of river water quality and riverbed silt, draining river water, introducing new water bodies, and managing riverbed aquatic organisms. Water quality testing indicators include pH value, conductivity, turbidity, chemical oxygen demand, ammonia nitrogen content, and total phosphorus content; sediment testing indicators include the content of organic matter in the sediment;

[0044] S2. Add water quality improvement additives into the river to improve water quality and provide a good living environment for microorganisms;

[0045] S3. Build wetland rivers and aquatic plants at the bottom of the river, cultivate duckweed on the river surface, and treat the riverbed with quicklime;

[0046] S4. Add fish and shrimp into the water body and perform oxygenation treatment;

[0047] S5. Planting lawns, forest belts and shrubs on both sides of the river;

[0048] S6. Maintain the river water environment, and regularly sample and test the water quality and silt for data comparison. The water quality test indicators include pH value, conductivity, turbidity, chemical oxygen demand, ammonia nitrogen content, and total phosphorus content; the sediment test indicator is the content of organic matter in the sediment.

[0049] The water quality improving additives in S2 include the following ingredients: zeolite powder, diatomaceous earth, trehalose, licorice powder, zinc yeast, and soap powder. The ingredients are ranked by mass as follows: 12 parts of zeolite powder, 10 parts of diatomaceous earth, 7 parts of trehalose, 6 parts of licorice powder, 0.3 parts of zinc yeast, 0.7 parts of soap powder, 3 parts of citric acid, 15 parts of wheat bran, and 13 parts of rice husk powder.

[0050] Water quality improvement additives can reduce the concentration of ammonia nitrogen and nitrite in sewage, promote the sedimentation of heavy metal pollutants, effectively improve water quality, and are beneficial to the growth of fish and shrimp.

[0051] The water surface cultivated duckweed in S3 is a floating plant with roots in the water and a floating leaf plant with roots in the riverbed mud. The floating plant with roots in the water can be one or more of water hyacinth, water hyacinth, etc., and the floating leaf plant with roots in the riverbed mud can be one or more of lotus, water turtle, etc.

[0052] Water bodies with abundant aquatic plants have good water quality and clear river channels. Artificial planting of aquatic plants is an important part of repairing the water ecosystem of rivers and river channels.

[0053] When raising fish and shrimp in the water in S4, it is necessary to mix herbivorous, omnivorous and carnivorous fish and shrimp. Climbing snails, clams, and other shellfish and a large number of benthic animals should be raised at the bottom of the water. The ratio of herbivorous, omnivorous and carnivorous fish and shrimp is 6:10:1.

[0054] Fish and shrimps swim freely in the water, creating ripples on the water surface, making the rivers and waterways appear vibrant. Shellfish such as snails and clams and a large number of benthic animals crawling on the bottom of the water form an ecosystem under the water.

[0055] In S4, aeration is performed to increase oxygen in the water body to promote the growth and reproduction of aerobic bacteria, thereby strengthening and accelerating the decomposition of organic pollutants in the water. A circulating water pump is used in the aeration process.

[0056] Oxygen release bacteria The survival and reproduction of bacteria, fungi, actinomycetes, soil protozoa and other biological populations that are invisible to the naked eye constantly decompose organic matter in the water into inorganic matter and water, and they need sufficient oxygen.

[0057] In S5, space is left on the river bank for afforestation on both sides, and trees with larger crowns are planted to gradually form a forest belt. Lawns are planted on the ground, and the tree crowns close to the bank extend over the river; lawns or shrubs are planted on the river slopes; and green climbing plants are planted on the land side of the water wall.

[0058] It can enhance the ecological function. When big trees are rooted in the soil, their deep and dense roots form a soil biological system with the lawn, which can play a landscape role. The forest belt lawn on the shore, combined with the river, can effectively improve the temperature and humidity in this area. The soil biological system formed by the lawn, shrubs and soil on the slope protection can also reduce the impact of organic matter on rivers and waterways and the degree of eutrophication, just like the trees and lawns on both sides. The roots of some shrubs can even extend directly into the water to absorb nutrients from the water. The river slope is a natural transition zone from water to land. The combination of lawn, shrubs and soil improves temperature and humidity and provides food. It stabilizes the slope and prevents soil erosion.

[0059] In S6, weeds, waste, and drifting garbage are removed at the edge of the water area to ensure smooth flow of water, maintain a good water environment, and keep the water surface clean and beautiful.
