[0023] A river sewage treatment dam, such as Figures 1-4As shown, a cavity 2 is provided in the dam body 1, and an opening 3 is provided at the bottom of the dam body 1 for river water to enter the cavity 2. A filter layer is provided at the opening 3, and a biological adsorption layer is provided on the top of the filter layer. A collecting device for collecting impurities in the river water is provided on the top of the biological adsorption layer. A cleaning port 4 is provided on the top of the dam body 1, and the cleaning port 4 is connected to the collecting device. A water outlet 5 is provided on the side of the dam body 1 away from the water storage direction, and the water outlet 5 is connected to the cavity 2. An interception net 24 is fixedly connected to the top of the dam body 1. Water in the river enters the dam body 1 from the opening 3, and then passes through the filter layer to filter out some solid impurities, and then enters the biological adsorption layer. The roots of organisms can absorb organic matter such as ammonia nitrogen in the sewage in the river, thereby reducing the ammonia nitrogen content of the river water and achieving the effect of treating the river water. By arranging the collecting device and the interception net 24, solid impurities in the river water can be intercepted and collected to prevent solid impurities from passing through the dam body 1 into the downstream, thereby improving the effect of river sewage treatment.

[0024] like Figure 3 As shown, the filter layer includes a support box 6 and several stones 9. The support box 6 is provided with a through hole 8 with a pore size smaller than the size of the stone 9. Several stones 9 are arranged in the support box 6. A through groove 7 is provided on the top of the support box 6. The through groove 7 is for the biological adsorption layer to extend into. The width of the support box 6 is consistent with the width of the cavity 2 and can fill the bottom of the cavity 2. The stones 9 are of different sizes, and the gaps between the stones 9 are small. River water can enter the support box 6 from the through hole 8. Solid impurities suspended in the river water can be intercepted by the stones 9, which plays a filtering role. The support box 6 can be used to place the stones 9 to prevent the stones 9 from shifting, thereby ensuring the stability of the stacking of the stones 9.

[0025] In one embodiment, the biological adsorption layer includes a filter box 10, which is filled with a number of fiber composite fillers 11, and a number of hydroponic plants 12 are planted in the fiber composite fillers 11. The roots of the hydroponic plants 12 are inserted into the gaps between the stones 9. The filter box 10 is used to hold the fiber composite fillers 11. The fiber composite fillers 11 are flexible and compressible, have large pores and strong pollution interception capabilities. Its working principle is based on the design of sparse top and dense bottom pores in the filter layer, which can further filter impurities. In addition, it has strong wear resistance and chemical corrosion resistance, is easy to backwash and restore, and can be used repeatedly. Several planting holes are dug in the fiber composite filler 11, which can be used to fix the hydroponic plants 12 and provide support for the hydroponic plants 12 so that they can stretch vertically. The roots of the hydroponic plants 12 can absorb organic matter in the river water, and provide growth nutrients to the hydroponic plants 12 in the process of treating the river water, thereby achieving a sustainable treatment effect.

[0026] like Figure 2-Figure 3The cleaning plate 14 is connected to the filter screen 13 and the cleaning plate 14 is connected to the filter screen 13 by the cleaning plate 14. ...

[0027] like Figure 2-Figure 3 As shown, the driving member includes two transmission ropes 16 and a motor 17. The output end of the motor 17 is fixedly connected to a pulley 18. A pulley 2 19 is provided below the pulley 18. The pulley 18 is rotatably connected to the dam body 1. A pulley 3 20 is provided on the side opposite to the pulley 18 and the pulley 2 19. The pulley 3 20 is rotatably connected to the dam body 1. The two transmission ropes 16 are rotatably connected to the pulley 18 and one of the pulleys 3 20 and the pulley 2 19 and the other pulley 3 20. The cleaning plate 14 is vertically fixedly connected to the two transmission ropes 16, and the motor 17 can drive the pulley 18 to rotate. Wheel 18 and pulley 2 19 rotate. Since pulley 18 is connected to pulley 3 20 by a transmission rope 16, it can also drive pulley 3 20 to rotate, so that the connecting rope can drive the cleaning plate 14 to move left and right. Support columns 21 are further fixedly connected on both sides of the dam body 1. An installation cavity 22 is opened in the support column 21. The motor 17, pulley 18, pulley 2 19 and pulley 3 20 are all arranged in the installation cavity 22. The installation cavity 22 is located at the top of the dam body 1. The river water will not overflow onto the motor 17, preventing the motor 17 from getting wet, thereby improving the service life of the motor 17.

[0028] Working principle:

[0029] The dam body 1 is only provided with an opening 3 at the bottom that is open to the river water, so the river water can enter the dam body 1 from the opening 3 at the bottom, so that the river water can flow along the preset path, and the river water can pass through the stone 9, the fiber composite filler 11 and the hydroponic plant 12 in sequence. The stone 9 can intercept solid impurities suspended in the river water. When passing through the fiber composite filler 11, the fiber composite filler 11 is flexible and compressible, has large pores and strong pollution interception ability, and can further filter impurities. Then the roots of the hydroponic plant 12 can absorb organic matter in the river water, and provide growth nutrients to the hydroponic plant 12 in the process of river water treatment, achieving a sustainable treatment effect. Finally, the purified river water can be discharged from the water outlet 5. In the process of intercepting and cleaning impurities, the cleaning plate 14 can be driven to move under the action of the motor 17 and pulley 1 18, pulley 2 19 and pulley 3 20, thereby cleaning the filter screen 13, so that the dam body 1 can be used continuously.
