Problems solved by technology
[0004] The disadvantage of the existing technology is that industrial sewage often contains heavy metal pollutants. These heavy metal pollutants will flow into the soil on both sides of the river along with the river water, causing secondary pollution to crops. With the transmission of the food chain, these heavy metal pollutants will It will accumulate in the animal body and affect the entire ecological environment

Embodiment
[0043] Embodiment: the ecological restoration method of river course aquatic plants, comprising the following steps:
[0044] S1, upstream 1 blocking;
[0045] Such as figure 1As shown, plants such as reeds, cattails or willows are planted on the river bottom of the upper reaches of the river 1 to form a plant grid 4, and the height of the plant grid 4 is greater than the height when the river swells. The side of the plant grid 4 facing the upstream 1 of the river is set in an inverted V shape, and the two ends of the side of the plant grid 4 are arc-shaped, and the arc is bent towards the downstream 3 of the river. The side of the plant grid 4 towards the downstream 3 of the river is V-shaped.
[0046] Such as figure 1 As shown, three biological ropes 5 are arranged near the side of the plant fence near the downstream 3, and the biological ropes 5 are arranged along the flow direction of the river; the two ends of the biological ropes 5 are respectively fixed on the revetm...

The invention discloses an ecological restoration method for aquatic plants of a river channel, and relates to the technical field of ecological environment restoration. The method includes the following steps of: 1, upstream blocking, a plant grid is arranged at the upstream of the river water, and the height of the plant grid is larger than the height of the river water when the river is swollen; 2, filtering the river water near the river banks; purification membranes are arranged on both sides of the river water, wherein the purification membranes are arranged in the river water; a functionalized nanofiber for adsorbing metal ions is arranged on the purification membrane; 3, purifying the water quality of the middle stream; a plant floating island is arranged at the middle of the riverwater, and both sides of the floating island are respectively fixed on the river banks on both sides through connecting pieces; the method realizes the effect of adsorbing heavy metal ions by arranging the functionalized nanofibers on the river banks at both sides of the river water.
Description
technical field [0001] The invention relates to the technical field of ecological environment restoration, more specifically, it relates to a method for ecological restoration of aquatic plants in river courses. Background technique [0002] With the development of agriculture and industry, some industrial and domestic sewage are directly discharged into the river. And some pesticides left in the soil flowed into the river with the rain, which made the ecological environment of the river unbalanced or even destroyed. [0003] The Chinese patent with the authorized announcement number CN102863126B and the authorized announcement date of April 30, 2014 discloses a method for purifying polluted river water in industrialized villages and towns and restoring the water environment ecology. The method is to divide the polluted river section in industrialized villages and towns into three consecutive different sections: water purification membrane filtration section, bio-grid filtr...
