[0028] The present invention will now be further described with reference to the accompanying drawings.

[0029] like Figures 1 to 6 As shown, a wastewater wetland ecological treatment device includes an ecological water storage tank 10 and a pre-treatment wastewater device 20. The pre-treatment wastewater device 20 is located on one side of the ecological water storage tank 10 and is used to filter the wastewater entering the ecological water storage tank 10. At least one float 30 is installed inside the ecological water storage tank 10. Two float plates 40 are connected to the outer surface of the float 30, and each float plate 40 is connected to a counterweight 41. The counterweight 41 is used to ensure the stability of the float plates 40 and prevent them from easily moving with the water flow. In this configuration, several plant purification structures are provided on both floats 40. Each plant purification structure includes a positioning component and a plant component on the float 40. The floats 30 and 40 are used to limit the position of the plant purification structures and prevent them from shifting. A float position adjustment structure 60 is connected to the float 30. The float position adjustment structure 60 is used to adjust the position of the float 30 inside the ecological water storage tank 10. The float position adjustment structure 60 includes a winding component and a connector. A float connection component is provided on the float 30 to connect the two floats 30.

[0030] The pre-treatment wastewater device 20 includes a treatment tank 21, which is located on one side of the ecological water storage tank 10. An inlet pipe is installed on the top side of the treatment tank 21 to transport wastewater into the tank. An inclined filter screen 22 is fixedly installed inside the treatment tank 21 to filter impurities in the wastewater and move them along the direction of the filter screen. A water pump 23 is fixedly installed on the bottom side inside the treatment tank 21, and a water delivery pipe 24 is fixedly connected to the outlet of the water pump 23. The water pump 23 and the water delivery pipe 24 are used to transport the filtered wastewater from inside the treatment tank 21 into the ecological water storage tank 10. A sludge discharge trough is provided on one side of the treatment tank 21. A sludge collection hood 25 corresponding to the position of the sludge discharge trough is provided on one side of the treatment tank 21. The sludge collection hood 25 is used to collect the impurities discharged from the sludge discharge trough. A filter basket 26 is provided inside the sludge collection hood 25. The filter basket 26 is used to filter the impurities discharged from inside the treatment tank 21 again. A return pipe 27 is connected to the bottom end of the sludge collection hood 25. The bottom end of the return pipe 27 is located inside the treatment tank 21 and is located below the filter screen 22. The return pipe 27 is connected to the ecological water storage tank 10. The return pipe 27 is used to return the sewage inside the sludge collection hood 25 back to the inside of the treatment tank 21.

[0031] Before entering the ecological water storage tank 10, the sewage first enters the treatment tank 21 through the sewage inlet pipe. At this time, the sewage can be filtered by the filter screen 22, and the impurities filtered by the filter screen 22 will enter the sewage collection hood 25 through the sewage discharge tank. The impurities entering the sewage collection hood 25 will be filtered by the filter basket 26. The filtered sewage will flow back to the treatment tank 21 through the return pipe 27. The water pump 23 is started, and the sewage inside the treatment tank 21 is transported to the ecological water storage tank 10 through the water supply pipe 24 for treatment.

[0032] It should be noted that a hanging rod is connected to the filter basket 26. The filter basket 26 is placed inside the dirt collection hood 25 by the hanging rod. This ensures that the filter basket 26 can perform the filtration operation stably while making it easy to place and remove the filter basket 26, and thus making it easier to clean the impurities inside the filter basket 26.

[0033] The winding assembly includes a bracket 61, on which a winding reel 62 is rotatably connected. Several fixing holes 63 are provided on both sides of the winding reel 62, arranged in a circumferential array about the position of the winding reel 62. Two symmetrical sides of the bracket 61 are threaded with fixing bolts 64, which correspond to the positions of the fixing holes 63 and can be inserted into the holes 63. A positioning component, either a bolt or an anchor, is provided on the bracket 61 to fix the bracket 61 to the ecological water storage tank 10.

[0034] The connector includes a winding rope 65 connected to the winding reel 62 and a first connecting ring 66 connected to the float 30. One end of the winding rope 65 is connected to a first connecting hook 67, which can be connected to the first connecting ring 66.

[0035] When adjusting the positions of the float plate 40 and the float 30, the bracket 61 is installed in a suitable position on the ecological water storage tank 10 through the positioning component. Then, the winding reel 62 is rotated to perform winding or unwinding operations. At this time, the winding rope 65, the first connecting ring 66 and the first connecting hook 67 can be moved to adjust the float 30 and the float plate 40 to the heavily polluted area. The winding reel 62 is fixed by inserting the fixing bolt 64 into the fixing hole 63 in a suitable position, so that the position of the winding reel 62 no longer moves. Thus, the plant purification structure is stably placed in the heavily polluted area and the sewage is purified.

[0036] The positioning component includes a positioning groove 42 formed on the float plate 40, a positioning sleeve 43 fixedly connected to the inner wall of the positioning groove 42, a plurality of first water-permeable holes 44 formed on the outer surface of the positioning sleeve 43, and a mesh cover 45 threadedly connected to the outer surface of the positioning sleeve 43.

[0037] The plant component includes a plant cultivation tube 46, which contains plants, which can be floating plants or other wetland plants with wastewater purification functions. The outer surface and bottom of the plant cultivation tube 46 are provided with several second water permeable holes 47, which can be connected to the first water permeable holes 44. A positioning block 48 is fixedly connected to the outer surface of the plant cultivation tube 46, and the positioning block 48 can be snapped into the inside of the positioning groove 42.

[0038] When the plant cultivation tube 46 needs to be placed on the float plate 40, the plant cultivation tube 46 is inserted into the positioning sleeve 43 and the positioning block 48 is inserted into the positioning groove 42. The positioning block 48 and the positioning groove 42 support the plant cultivation tube 46. At this time, the plant cultivation tube 46 floats on the water surface through the float plate 40. Water can enter the interior of the plant cultivation tube 46 through the first water permeable hole 44 and the second water permeable hole 47.

[0039] It should be noted that when the plants inside the plant cultivation tube 46 are floating plants, the net cover tube 45 is no longer installed. The plant cultivation tube 46 does not contain the soil required for plant cultivation. The plant roots pass directly through the second permeable hole 47 at the bottom of the plant cultivation tube 46 and come into contact with the sewage. When the plants inside the plant cultivation tube 46 are other wetland plants with sewage purification functions, the net cover tube 45 is connected to the positioning sleeve 43, and the plant cultivation tube 46 contains the soil required for plant cultivation. The net cover tube 45 can prevent the soil inside the plant cultivation tube 46 from being lost. The positioning block 48 has a groove, which facilitates the removal and placement of the positioning block 48.

[0040] The float connection assembly includes a second connecting ring 31 installed at one end of the float 30. A winding rod 32 is fixedly connected to the end of the float 30 away from the second connecting ring 31. The cross-sectional shape of the winding rod 32 is T-shaped. A connecting rope 33 is connected to the end of the winding rod 32. The connecting rope 33 can be wound around the surface of the winding rod 32. A second connecting hook 34 is connected to the end of the connecting rope 33. The second connecting hook 34 can be connected to the second connecting ring 31.

[0041] When it is necessary to connect two pontoons 30, the second connecting hook 34 on one pontoon 30 is connected to the second connecting ring 31 on the other pontoon 30. At this time, the two pontoons 30 are connected by the connecting rope 33, the second connecting hook 34 and the second connecting ring 31.

[0042] It should be noted that when the two floats 30 are not connected, the connecting rope 33 can be wrapped around the winding rod 32 to avoid the connecting rope 33 becoming tangled.

[0043] The ecological water storage tank 10 has a soil purification structure inside, which includes a surface layer 11, a filter layer 12, and a base layer 13. The filter layer 12 is located below the surface layer 11, and the base layer 13 is located below the filter layer 12. The base layer 13 is connected to the bottom side of the interior of the ecological water storage tank 10. Submersible plants are installed on the surface layer 11.

[0044] The surface layer 11 can be made of peat moss, which is conducive to planting submerged plants. The filter layer 12 is a sandy soil layer, and the base layer 13 is made of gravel or a porous medium. The filter layer 12 and the base layer 13 can be used to filter and treat sewage.

[0045] The ecological water storage tank 10 is equipped with a partition 14 inside. The partition 14 is used to divide the ecological water storage tank 10 into two spaces: one space is a sewage treatment space and the other space is a water purification space. Multiple permeable channels are opened on one side of the partition 14. The sewage treatment space and the water purification space can be connected through the permeable channels, so that the sewage purified in the sewage treatment space can enter the interior of the water purification space. The inner walls of the multiple permeable channels are fixedly connected with isolation nets.

[0046] It should be noted that the surface layer 11, filter layer 12 and base layer 13 are located inside the wastewater treatment space. The isolation net can prevent substances inside the surface layer 11, filter layer 12 and base layer 13 from entering the interior of the water purification space, and can ensure that the purified water can smoothly enter the interior of the water purification space. The interior of the water purification space is equipped with a drain pipe, which can be connected to a water pump to discharge the water inside the water purification space.
