A hollow fiber curtain biofilm 25 is arranged in the first water tank 2, and an overflow pipe 26 is connected to the first water tank 2. The end of the overflow pipe 26 away from the first water tank 2 is connected to a third water tank 27 fixedly installed on the base 1. A second pressure sensor 28 is fixedly installed in the third water tank 27, and the third water tank 27 is connected to a second water pump 32. The water outlet end of the second water pump 32 extends into the river or lake. A biological bacteria culture box 29 is fixedly installed on the side of the first water tank 2, and a connecting pipe 30 is connected to the biological bacteria culture box 29. The end of the connecting pipe 30 away from the biological bacteria culture box 29 is connected to the third water tank 27, and a flow meter 31 is fixedly installed on the connecting pipe 30.

[0023] A T-shaped mounting plate 23 is slidably installed on the side wall of the first water tank 2. The mounting plate 23 is fixed to the first water tank 2 by fixing screws. A filter plate 24 is fixedly installed on the side of the mounting plate 23 located inside the first water tank 2. The hollow fiber curtain-type biofilm 25 is fixedly installed on the surface of the filter plate 24 close to the closing plate 3.

[0024] A vertical pipe 33 is fixedly installed on the inner wall of the first water tank 2 , the vertical pipe 33 passes through the filter plate 24 and a slot for cooperating with the vertical pipe 33 is provided at the end of the filter plate 24 , and the water outlet end of the guide pipe 22 extends into the vertical pipe 33 near one end of the closing plate 3 .

[0025] The position where the overflow pipe 26 is connected to the first water tank 2 is located between the position where the filter plate 24 and the guide pipe 22 are connected to the first water tank 2 .

[0026] When the embodiment of the present invention is actually applied, the base 1 is pushed to move to the river or lake, and the pumping pipe 11 is installed in the river or lake through the installation component 35. The installation component 35 can adjust the position of the pumping pipe 11 according to the floating of the water surface and always make the pumping pipe 11 located below the water surface, thereby ensuring the stable extraction of river and lake water. The first water pump 12 extracts river and lake water through the pumping pipe 11 and transports it to the second water tank 5. The first pressure sensor 6 detects the pressure to determine the height of the river and lake water in the second water tank 5. The first pressure sensor 6 is electrically connected to the first water pump 12 to ensure that the river and lake water in the second water tank 5 is always in a stable state. After the river and lake water enters the second water tank 5, it enters along the drainage pipe 34. In the filter tank 13, the physical filter component 36 in the filter tank 13 can perform multiple deep filtrations on the river and lake water, thereby reducing the content of impurities in the subsequent river and lake water, which is beneficial to the subsequent ecological restoration. The filter components can be quickly replaced to ensure continuous filtration of river and lake water and ensure the efficiency of river and lake ecological restoration. The filtered river and lake water flows into the first water tank 2 through the guide pipe 22 and the vertical pipe 33. After that, the water level in the first water tank 2 gradually rises and the filter plate 24 and the hollow fiber curtain biofilm 25 are submerged. At this time, the hollow fiber curtain biofilm 25 can be used to perform deep biological filtration on the physically filtered river and lake water again. At the same time, the culture medium is cultured in the biological bacteria culture box 29, which is beneficial to The biological bacteria that improve the ecology of rivers and lakes, after the cultivation is completed, the culture solution containing the biological bacteria flows downward to the third water tank 27 through the connecting pipe 30, and the volume of the culture solution flowing into the third water tank 27 is detected by the flow meter 31, so as to judge the biological density of the biological bacteria, and then the river and lake water after deep filtration enters the third water tank 27 through the overflow pipe 26, and the volume of the river and lake water in the third water tank 27 is judged by the pressure reading detected by the second pressure sensor 28, so that the biological bacteria can be reasonably and evenly distributed in the third water tank 27 and reproduce and develop, and then the second water pump 32 will discharge the filtered biological bacteria in the third water tank 27 into the river and lake again, so that the biological bacteria can enter the river and lake ecology and slowly improve the river and lake ecology. The ecology is restored, the extraction of river and lake water is achieved, and the extracted river and lake water is physically and biologically filtered. Multi-stage filtration of river and lake water is achieved, and the filter components can be replaced while ensuring continuous filtration, thereby ensuring the efficiency of river and lake water filtration and improving the quality of river and lake water. After that, biological bacteria due to the river and lake ecology are put into the river and lake water, and the high-quality river and lake water carrying biological bacteria is returned to the original river and lake ecology, so that the river and lake ecology can be repaired through biological bacteria, and the biological bacteria are accelerated to reproduce in rivers and lakes, and then they can continue and accelerate the recovery of the river and lake ecology in the future. The improvement of the quality of river and lake water is conducive to accelerating the recovery of the ecology and is conducive to its use, thus realizing multi-mode ecological restoration and increasing the speed of ecological recovery.

[0027] like Figure 1As shown, as a preferred embodiment of the present invention, the mounting assembly 35 includes a fixing frame 7, the fixing frame 7 is set to a U-shaped structure and the end of the fixing frame 7 is set to a conical structure, the parallel sections on the fixing frame 7 are slidably mounted with a floating plate 8, and the surface of the floating plate 8 away from the horizontal section of the fixing frame 7 is fixedly mounted with a plurality of groups of spaced connecting rods 9, and the end of the connecting rod 9 away from the floating plate 8 is fixedly mounted with a filter basket 10.

[0028] The water suction pipe 11 is fixedly mounted on the filter basket 10 and the water inlet end of the water suction pipe 11 extends into the filter basket 10 .

[0029] When the embodiment of the present invention is actually used, the fixing frame 7 is inserted into a river or lake, and the floating plate 8 floats on the water surface. At this time, the filter basket 10 is immersed in the water, so that the water in the river or lake can be extracted through the pumping pipe 11, and the larger garbage in the river or lake is filtered through the filter basket 10, so as to avoid clogging the pumping pipe 11 and ensure the stable extraction of water flow. The filter basket 10 is lowered to a certain depth through the connecting rod 9, so as to ensure that the pumping pipe 11 is always located below the water surface when the floating plate 8 moves up and down, which is conducive to the extraction of water flow.

[0030] like Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, as a preferred embodiment of the present invention, the physical filtration component 36 includes a bracket 14, and the bracket 14 is provided with multiple groups and fixedly installed on the filter tank 13. The bracket 14 is arranged in an L-shaped structure and is linearly spaced along the water flow direction on the filter tank 13. The horizontal section of the bracket 14 is threadedly connected with a threaded rod 15, and the threaded rod 15 passes through the bracket 14 and points to the filter tank 13. One end of the threaded rod 15 close to the filter tank 13 is rotatably connected to a mounting frame 16 slidably installed in the filter tank 13. The mounting frame 16 passes through the side wall of the filter tank 13. Along the water flow direction, every two groups of mounting frames 16 are detachably connected with a filter screen 18 and an activated carbon filter screen 21.

The second magnetic strips 20 are used in conjunction with the first magnetic strips 19 for pressing the filter screen 18 and the activated carbon filter screen 21.

[0032] In actual application, the filter screen 18 is installed in the two groups of installation frames 16 on the front side that are in contact with the water flow, and then the first magnetic strip 19 is placed at the position of the second magnetic strip 20, so that the second magnetic strip 20 adsorbs the first magnetic strip 19, and the filter screen 18 is pressed against the grid plate 17 through the first magnetic strip 19, so that the filter screen 18 is fixed. Similarly, the activated carbon filter screen 21 is installed and fixed in the two groups of installation frames 16 on the rear side. When filtering river and lake water, the threaded rod 15 is rotated to drive the installation frame 16 to move, so that each group of installation frames 16 installed with the filter screen 18 and the activated carbon filter screen 21 enters the filter tank 13, and the other two groups of installation frames 16 installed with the filter screen 18 and the activated carbon filter screen 21 are located On the outside of the filter tank 13, during filtration, the river and lake water first contacts and is filtered with the filter screen 18 on the front side, and then is deeply filtered with the activated carbon filter screen 21 again, thereby performing multiple physical filtrations of the river and lake water and improving the filtration effect. After long-term use, another set of installation frames 16 equipped with the filter screen 18 and the activated carbon filter screen 21 are moved into the filter tank 13, and the installation frame 16 equipped with the filter screen 18 and the activated carbon filter screen 21 after use is moved outside the filter tank 13. At this time, the first magnetic strip 19 can be removed to take out and replace the filter screen 18 and the activated carbon filter screen 21. Repeating the above steps can realize quick replacement of the filter components, and can ensure continuous filtration of river and lake water to ensure the efficiency of river and lake ecological restoration.
