Embodiment 1

[0037] as attached figure 1 and image 3 As shown, the water-land ecotone pollution repair system includes river bank polluted soil 1 and polluted water body 2, potted clonal plants 3 are buried in the river bank polluted soil 1 in the area to be repaired, and bottom nets 4 are set in the polluted water body 2 in the area to be repaired , Set up a fence net 5 at the border of the area to be repaired. Set slope slope 6 on the outside of the pot of the potted clonal plant and the position of the polluted soil, to avoid the breakage caused by the suspension when the plant grows from the inside of the pot to the outside.

[0038] The top of the pot of the potted clonal plant 3 is buried higher than the surface of the polluted soil 1 on the river bank.

[0039] The clonal plant is Neptonia chinensis.

[0040] The restoration method of the pollution restoration system in the above-mentioned water and land crisscross zone comprises the following steps:

[0041] (1) Cultivate plan...

Embodiment 2

[0055] Such as figure 2 and image 3 As shown, the water-land ecotone pollution restoration system includes riverbank polluted soil 1 and polluted water body 2, potted clonal plants 3 are buried in the riverbank polluted soil 1 in the area to be repaired, and a bottom net 4 is set in the polluted water body in the area to be repaired. Set fence net 5 at the boundary of the area to be repaired. Set slope slope 6 on the outside of the pot of the potted clonal plant and the position of the polluted soil, to avoid the breakage caused by the suspension when the plant grows from the inside of the pot to the outside.

[0056] The top of the pot of the potted clonal plant is buried higher than the surface of the polluted soil on the river bank.

[0057] The clonal plant is Neptonia chinensis.

[0058] The restoration method of the pollution restoration system in the above-mentioned water and land crisscross zone comprises the following steps:

[0059] (1) Cultivate plants

[006...

Embodiment 3

[0074] The same as the pollution repair system and repair method in the amphibious zone of embodiment 2, the difference is that if the scope of the area to be repaired is relatively large, the potted stolon type amphibious plants can be buried in rows on the polluted soil of the river bank, and the distance between each row is It is 120-150cm.

[0075] The above-mentioned embodiment is also applicable to other stolon-type amphibious plants such as Lishihe and Paspalum bistica. Transplant to the polluted environment to continue culturing, so as to repair the polluted environment.

[0076] Figure 4 A schematic diagram of clonal plant growth in the repair system described above is shown. The left box represents polluted soil, and the right box represents polluted water bodies. Clonal plants can expand, grow and restore in polluted soil, polluted water bodies, and water-shore exchange areas. When the contaminated soil area is large, the clonal plants can be arranged in rows. ...

Abstract

The invention relates to the technical field of environmental restoration, especially to a lake-land ecozone contamination remediation system and a remediation method. The lake-land ecozone contamination remediation system comprises riverbank contaminated soil and contaminated water. Pot clonal plants are embedded in riverbank contaminated soil in an area to be remediated, a bottom net is arrangedin the contaminated water in the area to be remediated, and fence mesh is arranged at the boundary of the area to be remediated. The remediation method comprises the following steps: cultivation of plants, arrangement of the bottom net, plant transplantation, arrangement of the fence mesh and harvesting at fixed time. According to the lake-land ecozone contamination remediation system, amphibiousclonal plants are adopted to create a good remediation environment for the contaminated lake-land ectone, remediation of contaminated water, lake-land ecozone and riverbank contaminated soil is guaranteed, and the trouble and disadvantage that contaminated water, lake-land ecozone and riverbank contaminated soil are separately remediated in the prior art are avoided.

Description

Technical field: [0001] The invention relates to the technical field of ecological environment restoration, and in particular to a pollution restoration system and restoration method in a water-land ecotone. Background technique: [0002] Water environmental pollution can usually be divided into point source pollution and non-point source pollution. Point source pollution mainly includes industrial wastewater and urban domestic sewage pollution. Usually, there are fixed sewage outlets for centralized discharge. Non-point source pollution is exactly the opposite of point source pollution. Refers to dissolved and solid pollutants flowing into receiving water bodies (including rivers, lakes, reservoirs, bays, etc.) through the runoff process under the action of precipitation (or snowmelt) from unspecified locations and causing eutrophication of water bodies chemical or other forms of pollution such as heavy metals. The U.S. Clean Water Act Amendment (1997) defines non-point so...
