[0044] The embodiment of the present application provides a system 10 for regulating an artificial river with high eutrophication flow rate, so as to solve the problems that it is difficult to carry out overall ecological transformation of existing artificial rivers, the artificial river has a high eutrophication degree and a fast flow rate, resulting in a very low survival area of ​​aquatic plants 200, and even if the aquatic plants 200 survive, they are concentrated on the shore, and the reduction effect of pollutants in the artificial river water body is limited. The system 10 for regulating an artificial river with high eutrophication flow rate will be described below in conjunction with the accompanying drawings.

[0045] The system 10 for regulating eutrophic high-velocity artificial river provided in the embodiment of the present application is exemplary, see Figure 1 As shown, Figure 1 The schematic side view of the system 10 for regulating eutrophication and high-velocity artificial river provided in the embodiment of the present application. The system 10 for regulating eutrophication and high-velocity artificial river provided in the present application can be used for artificial river regulation.

[0046] In order to more clearly illustrate the structure of the eutrophication and high-flow rate artificial river channel regulation system 10 , the eutrophication and high-flow rate artificial river channel regulation system 10 will be introduced below with reference to the accompanying drawings.

[0047] For example, see Figure 1 As shown, a system 10 for regulating eutrophication and high-velocity artificial rivers includes a permeable reaction filter wall 100, aquatic plants 200, and a guide pipe 300.

[0048] The permeable reaction filter wall 100 is used to be set in the river channel 20 to be managed and arranged along the water flow direction perpendicular to the river channel 20 to be managed. The diversion pipe 300 is installed on the permeable reaction filter wall 100 and penetrates the permeable reaction filter wall 100. The diversion pipe 300 is used to conduct water flow on both sides of the front and back surfaces of the permeable reaction filter wall 100. The area of ​​the river channel 20 to be managed located on the back surface of the permeable reaction filter wall 100 and below the diversion pipe 300 forms a planting area. Aquatic plants 200 are planted in the planting area.

[0049] The system 10 for regulating eutrophic high-velocity artificial rivers of this embodiment performs ecological restoration of artificial rivers by solving the velocity problem, avoiding the problem that the water flow is too fast and the drag force on the plants is stronger, which causes the newly planted aquatic plants 200 to fail to take root smoothly. Secondly, this application solves the problem of pollutant reduction to ensure the safety of the downstream receiving water body. The present invention constructs a mature and stable aquatic plant 200 community in the artificial river, which not only improves the physical and chemical properties of the riverbed mud but also improves the living environment of microorganisms. At the same time, the whole system has a stronger ability to absorb and reduce pollutants, and the system stability is higher, so as to enhance the self-purification ability of the artificial river itself, thereby alleviating the water environment pressure faced by the downstream water body.

[0050] In some of these embodiments, see Figure 2 As shown, the system 10 for regulating eutrophication and high-velocity artificial rivers also includes a filter assembly 400. The filter assembly 400 is used to be arranged in the river 20 to be regulated on the water-facing surface of the permeable reaction filter wall 100. The purpose of the filter assembly 400 is to filter impurities and foreign matter in the water body in advance. During the regulation stage, the impurities and foreign matter intercepted by the filter assembly 400 need to be cleaned regularly.

[0051] In some embodiments, the filter assembly 400 may be a filter screen. Preferably, the filter screen may be a strong and durable screen. The pore size of the filter screen may be set as required.

[0052] In some embodiments, the filter assembly 400 completely covers the water-facing surface of the permeable reactive filter wall 100 .

[0053] In some of these embodiments, see Figure 1As shown, the system 10 for regulating eutrophic high-velocity artificial rivers also includes a connector 500 and an anchor 600. The anchor 600 is used to be fixed in the river 20 to be regulated. Both sides of the permeable reaction filter wall 100 are respectively arranged on the anchors 600. Each anchor 600 is connected to the permeable reaction filter wall 100 through the connector 500 to fix the permeable reaction filter wall 100. The arrangement of the connector 500 and the anchor 600 in this embodiment can improve the strength of the permeable reaction filter wall 100, avoid the impact of the high-velocity water body in the artificial river on the permeable reaction filter wall 100, and improve the service life of the permeable reaction filter wall 100.

[0054] In some embodiments, the number of anchors 600 on both sides of the permeable reaction filter wall 100 is multiple. Preferably, the filter assembly 400 is connected to the multiple connectors 500 on the water-facing side of the permeable reaction filter wall 100. That is, the filter assembly 400 is connected to the multiple connectors 500 on the water-facing side of the permeable reaction filter wall 100, which is convenient for installation and reduces equipment investment costs.

[0055] In some of these embodiments, see Figure 1 As shown, the permeable reaction filter wall 100 includes an upper zeolite packing layer 101 and a lower crushed stone packing layer 102. The height of the zeolite packing layer 101 is greater than that of the crushed stone packing layer 102.

[0056] In some of these embodiments, see Figure 1 As shown, the system 10 for regulating eutrophication and high-velocity artificial river channels further includes a support 700. The support 700 is used to be arranged in the river channel 20 to be regulated and located on the back side of the permeable reaction filter wall 100, and the support 700 is used to support the guide pipe 300.

[0057] In some embodiments, the support member 700 may be a wooden pile. It is not difficult to understand that in other embodiments, the support member 700 may also be a cement pile, a metal pile, etc.

[0058] In some of these embodiments, see Figure 2 As shown, there are multiple flow guide pipes 300. Multiple flow guide pipes 300 are distributed at intervals. The number of flow guide pipes 300 is multiple, which can increase the flow rate of the water body. The heights of the multiple flow guide pipes 300 can be the same. It is not difficult to understand that the heights of the multiple flow guide pipes 300 can also be different, and can be specifically set according to actual needs.

[0059] In some of these embodiments, see Figure 1 As shown, the flow guide pipe 300 is located at the upper middle position of the permeable reaction filter wall 100. Preferably, the flow guide pipe 300 is located close to the top position of the permeable reaction filter wall 100.

[0060] In some of these embodiments, see Figure 1 As shown, the system 10 for regulating eutrophic high-velocity artificial rivers also includes a fish interception net 800. The fish interception net 800 is used to be set in the river channel 20 to be regulated and is located on the side of the back water surface of the permeable reaction filter wall 100. The fish interception net 800 is located at the outlet of the diversion pipe 300, and the area of ​​the river channel 20 to be regulated between the permeable reaction filter wall 100 and the fish interception net 800 forms a planting area.

[0061] In some embodiments, the aquatic plants 200 can be selected as needed, for example, the aquatic plants 200 are emergent plants and submerged plants with well-developed root systems, large biomass and ornamental value. Preferably, the aquatic plants 200 include one or more of the emergent plants canna, calamus, reed, lily, cattail, Vallisneria, Malayan pondweed, foxtail algae, hornwort and black algae.
