Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be further described in detail with reference to the following embodiments.

As shown in fig. 1, the blanket for cleaning submerged plants for purifying water comprises a blanket body 1, wherein the blanket body 1 may be a square blanket, and the periphery of the blanket body 1 is fixed by a fixing plate 2. The fixing plate 2 can be made of hard material, a row of sharp spines 21 is arranged at the lower end of the fixing plate 2, and the length of the sharp spines 21 is the thickness of the plant blanket body 1. The purpose of the spikes 21 is to secure the plant blanket body 1 against being washed away by water flow. The outer side surface of the fixing plate 2 is provided with scales, so that the installation height of the plant blanket body 1 can be unified by an operator conveniently.

In order to realize the planting function of the plant carpet body 1, the plant carpet body 1 is arranged as follows:

the plant blanket body 1 sequentially comprises an attachment layer 11, a fiber net layer 12, a matrix layer 13 and a root system cultivation layer 14 from top to bottom. The attachment layer 11 is a three-dimensional net structure made of coconut shells, the thickness of the attachment layer is 0.5-1cm, the attachment layer is made of a plant fiber net, the aperture of the attachment layer is 3-5cm, and plankton can be captured. The adhering layer 11 and the fiber net layer 12 are separated by a certain distance, and the separation distance is 2-7 cm. The unique design can facilitate the survival and propagation of plankton and the construction of the ecological community of the plant blanket body 1. The fiber net layer 12 in this embodiment is woven by coconut shells or bamboo and wood fibers, and the planting holes 121 are formed in the fiber net layer 12, so that the submerged plant a can grow and stretch out conveniently.

The thickness of the fiber net layer is 6cm, the fiber net layer plays a role in fixing the submerged plant A, the submerged plant is convenient to fix and attach, and root-tying growth of the submerged plant A is further facilitated.

The matrix layer 13 in this embodiment contains organic matter suitable for the growth of the submerged plant a, specifically, 50% of humus, 40% of sludge, and 10% of slow-release curing agent. Of course, the organic matter can be adjusted according to different submerged plants. The slow-release curing agent can be selected from urea isobutyraldehyde, urea hexanal, oxamide and the like. The bottom of the substrate layer 13 is set to be wavy, so that the bottom of the substrate layer 13 is sealed by the braided layer 131, the braided layer 131 is set to be wavy, the braided layer 131 can be formed by braiding naturally degradable braided fabrics, the braided gaps are more, and the root system of the submerged plant A can grow out of the braided gaps conveniently. In this embodiment, the submerged plant a is planted in the trough of the wave-shaped braid 131. The naturally degradable braided fabric can be naturally degraded by water, and secondary pollution after treatment can not be caused.

Below the woven layer 131 is the root system cultivating layer 14, and the woven layer 131 is not in contact with the root system cultivating layer 14. The root system cultivation layer 14 is of a honeycomb structure, and the root system cultivation layer 14 is made of polylactic acid. The honeycomb structure is formed by closely arranging a plurality of vertical through regular hexagons together, the thickness of the root system cultivation layer 14 is 8cm, the side length of each regular hexagon is 0.01-0.1cm, and the regular hexagons with different side lengths can be arranged in a staggered mode.

The root system cultivation layer 14 adopts a honeycomb structure, so that the submerged plant A can conveniently go deep into the root system cultivation layer, and the root system can be conveniently rooted and prolonged in the vertical growth. The embodiment adopts polylactic acid to prepare the honeycomb structure, and the honeycomb structure is degradable and environment-friendly. The polylactic acid of this embodiment can degrade the release carbon dioxide, and the bottom of matrix layer 13 sets up the wavy, leads to the carbon dioxide bubble of release to gather in wavy top, and the carbon dioxide bubble can be absorbed by submerged plant's root, is convenient for grow. Moreover, the weaving layer can disperse the carbon dioxide bubble, and the little bubble of dispersed carbon dioxide is because the effect of buoyancy for the little bubble of carbon dioxide slowly rises, finally is caught by the submerged plant leaf that is located the top of adhesion layer 11, carries out photosynthesis, further promotes the growth of submerged plant. Both guaranteed the vertical root of submerged plant A above and extended, honeycomb decomposes simultaneously, and the submerged plant pricks root direct contact silt, plays fine root system transition, reaches and pricks the fixed purpose of root.

When the embodiment is used, seeds or plants are planted at the valley of the substrate layer 13, the spines 21 of the fixing plate 2 are inserted into silt at the river bottom or the lake bottom, the depth is adjusted according to the scales, and the root system cultivation layer 14 is just inserted into the silt, so that the submerged plants can grow conveniently. Finally, the root system cultivating layer 14 is completely degraded, and the root system is completely rooted in the sludge. And the carbon dioxide degraded by the root system cultivation layer 14 further promotes the photosynthesis of the submerged plant and the growth of the submerged plant.

The embodiment has good environmental protection effect, does not produce secondary pollution, has high planting rate of submerged plants and higher purification efficiency of water.

The above embodiments are only for illustrating the technical concept and features of the present invention, and the purpose thereof is to enable those skilled in the art to understand the contents of the present invention and to implement the present invention, which cannot limit the protection scope of the present invention. All equivalent changes and modifications made according to the spirit of the present invention should be covered by the protection scope of the present invention.
