DETAILED DESCRIPTION

[0036] like Figure 1-14In the present invention, a shallow lake ecological slope protection purification treatment system includes a buffer zone 11, a control zone 12 and a storage zone 13. The main lake area 14 is located on the side of the storage zone 13 that is farther from the control zone 12. A biological reticular membrane 10 is provided between the storage zone 13 and the main lake area 14. A plurality of superimposed ecological frames 3 are provided on the side of the control zone 12 close to the buffer zone 11. The ecological frames 3 are filled with zeolite-limestone fillers 4. Emergent plants 5 are provided in the ecological frames 3. The ecological frames 3 are used to form a closed barrier structure. The entire system is arranged along the shoreline with serious non-point source pollution, with a width of 15.5m, of which the buffer zone 11 is 4m wide, the control zone 12 is 1.5m wide, and the storage zone 13 is 10m wide. The regulation area 13 and the main lake area 14 are separated by a biological mesh 10. A galvanized steel pipe of 6mφ80 is set every 3m on the biological mesh 10 to facilitate the fixation of the mesh and prevent the biological mesh 10 from being damaged by excessive wind and waves. At the same time, aquatic plants with high nitrogen removal efficiency, aquatic canna, are planted in each ecological frame 3. Two submerged plant planting areas (with a planting width of 5m) are arranged along the lakeshore of the regulation area 13. The ecological frame 3 adopts the principle of gravity retaining wall to increase the content of nitrite, which is more conducive to anaerobic ammonia oxidation and improves the nitrogen removal rate. With this structure, when the pollutants from the upstream enter the lake, they will be blocked by the ecological frame 3. At the same time, the buffer zone 11 slows down the pollutants, which maximizes the denitrification efficiency of the ecological slope protection, thereby obtaining a better purification effect. The microbial agent 15 is artificially sprayed to attach it to the biological mesh 10, and the surface water flow generated by natural wind is used to continuously filter the suspended particles in the water body.

[0037] In the preferred scheme, the buffer zone 11 includes a garden path 1 and a green turf 2, a crushed stone cushion layer 6 is provided at the end of the control zone 12 near the green turf 2, the ecological frame 3 is against the crushed stone cushion layer 6, and the storage area 13 is provided with foxtail algae 8 and dwarf vallisneria 9. The buffer zone 11 is divided into two areas, which are a garden path 1 with a slope of 3‰ and a width of 2m and a green turf 2 with a slope of 15% and a width of 2m, respectively, which are paved with permeable bricks, and the amount of pollutants entering the lake along the lake shoreline around the lake is reduced by allowing natural precipitation to quickly penetrate the surface. The control zone 12 is arranged with 2 rows of 1.5m wide stepped ecological frames, and the shoreline is paved with geotextiles 7. After paving, a 10cm thick crushed stone cushion layer is laid on it and compacted as the foundation of the ecological frame, wherein the foxtail algae plant height is 15-30cm, the planting density is 10 plants / m2, and the dwarf vallisneria plant height is 10-20cm, and the planting density is 100 plants / m2. With this structure, it is possible to ensure strong survival adaptability, rapid biomass accumulation and strong pollution resistance, thereby quickly forming a stable ecological environment. The adsorption of foxtail algae 8 and dwarf vallisneria 9 can quickly improve the transparency of the water body and reduce the concentration of nutrient salts in the water body. By constructing the water ecosystem in the regulation and storage area 13, the self-purification capacity of the water body is improved and the concentration of nutrient salts in the water body is effectively degraded.

[0038] In the preferred scheme, multiple baffles 16 are provided in the ecological frame 3, and two adjacent ecological frames 3 are connected by positive and negative wire anchor rods 19. The upper layer is covered with 20cm nutrient planting soil. Considering the treatment effect and preventing clogging, 10mm zeolite and 20mm limestone are selected, and three baffles 16 are set. The baffle is 60cm long, 40cm high, and 5cm thick, which increases the contact area and contact time of surface source pollutants along the lake shoreline with zeolite-limestone, and improves the denitrification efficiency of pollutants entering the lake. Emergent plants 5-aquatic canna are planted in the ecological frame, with a plant height of 30cm and a planting density of 10 plants / m2, which purifies the water body while increasing the landscape effect. Thus, the structure is used to increase the treatment path of surface runoff into the lake through the setting of baffles 16, increase the denitrification efficiency of ecological slope protection, and simultaneously, the two adjacent ecological frames 3 can play a role of common protection, and the overall force is more balanced, and the ability to resist being impacted and leaving the gravel cushion layer 6 is higher.

[0039] In the preferred solution, two connecting blocks 302 are respectively provided on both sides of the eco-frame 3, and the two connecting blocks 302 are respectively threadedly connected to the positive and negative thread anchor rods 19, and a rotating ring 20 is provided in the middle of the positive and negative thread anchor rods 19. With this structure, it is convenient to connect two eco-frames 3 of the same height, and the positive and negative thread screw rods 19 can be driven to position and lock by rotating the rotating ring 20 with a tool, which is easy to operate and has a good effect.

[0040] In the preferred solution, a plurality of positioning holes 301 are provided on the upper part of the eco-frame 3, positioning screw sleeves 18 are embedded in the positioning holes 301, and an adjustable anchoring device 17 is provided in the positioning screw sleeve 18. The adjustable anchoring device 17 is used to fix the eco-frame 3 to the riverbed. With this structure, the adjustable anchoring device 17 can conveniently and firmly fix the eco-frame 3 at a set position, and can be installed and removed as needed, which is convenient to operate and has a good effect.

[0041] In a preferred solution, the adjustable anchoring device 17 includes a sleeve 1701, a thread 1702 is provided on the outside of the sleeve 1701, the thread 1702 is in the same direction as the positioning screw sleeve 18, a wedge head 1703 is provided at the bottom of the sleeve 1701, and an auxiliary ring 1704 is provided on the outside of the wedge head 1703. With this structure, the wedge head 1703 can be inserted into the soil of the riverbed by rotating the sleeve 1701, and the depth and strength of the locking of the wedge head 1703 can be adjusted by adjusting the position of the sleeve 1701. The auxiliary ring 1704 is a spiral ring, which can better enter the riverbed soil.

[0042] In the preferred embodiment, a straight extension portion 1705 is provided between the wedging head 1703 and the sleeve 1701, the outer diameters of the wedging head 1703 and the straight extension portion 1705 are smaller than those of the sleeve 1701, a plurality of through grooves 1706 are penetrated through the outer side of the straight extension portion 1705, an avoidance hole 1716 is provided inside the straight extension portion 1705, a disc 1707 is provided on the upper side of the wedging head 1703, a second movable rod 1711 is hinged on the disc 1707, the second movable rod 1711 is connected to the first movable rod 1710 through a pin 1708, the first movable rod 1710 is penetrated in the through groove 1706, a driving rod 1709 for driving action is provided on the upper part of the first movable rod 1710, and the driving rod 1709 and the first movable rod 1710 are hinged. With this structure, the position of the driving rod 1709 can be adjusted, thereby changing the position and shape of the first movable rod 1710 and the second movable rod 1711. At the same time, since the outer diameter of the wedging head 1703 and the straight extension part 1705 is smaller than that of the sleeve 1701, it is ensured that they enter the positioning screw sleeve 18 without interference. When the straight extension part 1705 extends from the bottom of the ecological frame 3, the driving rod 1709 is rotated to open the first movable rod 1710 and the second movable rod 1711. When the wedging head 1703 is continuously inserted into the riverbed soil, the soil also enters the gap between the first movable rod 1710 and the second movable rod 1711 to fill it. At this time, the sleeve 1701 is firmly held by the riverbed.

[0043] In the preferred solution, a threaded hole 1713 is provided through the middle of the sleeve 1701, the driving rod 1709 is threadedly connected to the threaded hole 1713, a conversion joint 1715 is provided at the bottom of the driving rod 1709 for rotation, and the first movable rod 1710 is hinged to the conversion joint 1715.

[0044] In the preferred solution, the first movable rod 1710 and the second movable rod 1711 are symmetrically provided with pointed heads 1714 on both sides. The pointed heads 1714 have a triangular cross section and a structure such that the first movable rod 1710 and the second movable rod 1711 can push away the surrounding soil when rotating, and also better wedge into the soil. After the soil gradually covers the first movable rod 1710 and the second movable rod 1711, the overall stability is greatly improved.

[0045] In the preferred embodiment, a plurality of second vent holes 1717 are provided on one side of the straight extension portion 1705 close to the wedging head 1703, a plurality of first hinge seats 1718 are provided on the disc 1707 along the circumferential direction, the first hinge seats 1718 are hinged to the second movable rod 1711, the adapter 1715 includes a limit ring 1722, a cylinder 1721 and a bottom plate 1719 arranged from top to bottom, a third vent hole 1723 is arranged through the adapter 1715, a plurality of second hinge seats 1720 are provided on the outer side of the bottom plate 1719, and the first movable rod 1710 and the second hinge seat 1720 are hinged;

[0046] A mounting hole 1724 and a countersunk hole 1725 are provided on one side of the driving rod 1709. The first vent hole 1712 is set through the middle of the driving rod 1709. The size of the countersunk hole 1725 matches the size of the limit ring 1722, and the size of the pointed head 1714 matches the size of the cylinder 1721.

After being screwed into the riverbed soil, the avoidance hole 1716 and each vent hole will be blocked. Therefore, when it is necessary to remove the adjustable anchor device 17, the first vent hole 1712 is blown to apply pressure, so as to blow away the soil at the position of each vent hole that may be blocked. At this time, the sleeve 1701 is continuously rotated in the opposite direction to remove the wedge head 1703. If the removal process is not smooth, keep blowing until the whole is completely removed. The design is ingenious, which can ensure that the ecological frame 3 is stably fixed in the riverbed soil and can also be easily disassembled.
