The bottom of the box 1 contacts the bottom of the wetland, and the planting layer 2 is lower than the liquid level of the wetland water body. The above-mentioned liquid level difference causes the siphon tube 1 4 and the siphon tube 2 5 to produce siphoning. The isolation net 9 blocks the silt at the bottom of the wetland water body, so that the water in the silt can be drained into the filter 8 and siphoned by the siphon tube 1 4 to the starting end of the water flow channel of the planting layer 2.

After multi-stage adsorption, the water is input into the transfer box 7 through the overflow pipe, and the pump assembly is operated to discharge the water in the transfer box 7, thereby realizing the distinction and limitation of the water source, being able to obtain the water at the bottom and middle surface of the wetland water body, and performing targeted adsorption treatment on different water bodies.

[0031] Example 2: Figures 1 to 4 , Fig.11As shown, on the basis of Example 1, the pump assembly includes a pump casing 10, a water outlet pipe 11, an impeller 12, a duct pipe 13, a turbine 14 and a transmission shaft 15, the pump casing 10 is installed on the outer wall of the transfer box 7, the water inlet end of the pump casing 10 is connected to the interior of the transfer box 7, the lower end of the water outlet pipe 11 is connected to the water outlet end of the pump casing 10, the impeller 12 is rotatably installed in the pump casing 10, the cross beam 33 is installed on the box body 1, the duct pipe 13 is installed on the cross beam 33, the duct pipe 13 is a trumpet type, the turbine 14 is rotatably installed in the duct pipe 13, one end of the transmission shaft 15 is transmission-connected to the impeller 12, and the other end of the transmission shaft 15 is transmission-connected to the turbine 14; it also includes a support leg 16, the support leg 16 is installed on the cross beam 33, and the support leg 16 cooperates with the cross beam 33 to assist in supporting the box body 1.

[0032] The water in the transfer box 7 enters the pump casing 10 through the water inlet end of the impeller 12, and the large mouth end of the duct pipe 13 is the water inlet end, so that the large mouth end of the duct pipe 13 faces the direction of the wetland water body, so that the incoming water enters the duct pipe 13 and is forced to be compressed when flowing, thereby increasing the flow rate of the water body inside the duct pipe 13, and the high-speed water flow drives the turbine 14 to rotate, and the turbine 14 drives the impeller 12 to rotate through the transmission shaft 15, so that the water in the pump casing 10 is discharged through the outlet pipe 11, so that no additional power source is required, and it can be arranged in remote waters.

The light-transmitting plate 23 is provided with sockets matching the multiple screw rods 22, and the multiple screw rods 22 respectively pass through the sockets of the light-transmitting plate 23, and the multiple nut plates 24 are rotatably screwed on the multiple screw rods 22, and the multiple nut plates 24 fix the light-transmitting plate 23 on the multiple screw rods 22; it also includes a lens 25, a lens 26 and a focusing plate 27, the lens 25 and the lens 26 are arranged on the light-transmitting plate 23, and the focusing plate 27 is installed at the end of the water flow channel of the planting layer 2; it also includes a solar panel 28 and a positioner 29, the solar panel 28 and the positioner 29 are installed on the light-transmitting plate 23, and the solar panel 28 is electrically connected to the positioner 29.

The light-transmitting plate 23 blocks the light opening of the box body 1, and prevents rainwater from entering without affecting the lighting of the plants. It is practical. Lens 1 25 gathers sunlight to the plants on the planting layer 2 to improve the lighting efficiency of the plants. Lens 2 26 focuses sunlight to the focusing plate 27, so that the water flowing through the focusing plate 27 is heated, and the pollutants in the water are decomposed at high temperature, thereby improving the adsorption and discharge efficiency of pollutants. The solar panel 28 generates and stores electricity in the sunlight, and supplies power to the positioner 29. The box body 1 is positioned by the positioner 29.

After the primary plant adsorption, the water body falls into the topmost microbial layer 3 through the water flow holes of the planting layer 2, and flows through multiple microbial layers 3 in turn for multi-stage adsorption of microalgae and bacteria. After multi-stage adsorption, the water body is input into the transfer box 7 through the overflow pipe, and finally the water body in the transfer box 7 enters the pump casing 10 through the water inlet end of the impeller 12. When the incoming water enters the duct pipe 13, it is forced to be compressed, thereby increasing the flow rate of the water body inside the duct pipe 13, and the high-speed water flow drives the turbine 14 to rotate, and the turbine 14 drives the impeller 12 to rotate through the transmission shaft 15, so that the water in the pump casing 10 can be discharged through the outlet pipe 11.
