[0032] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0033] In the description of the present invention, it should be understood that the terms "open hole", "upper", "lower", "thickness", "top", "middle", "length", "inner", "periphery", etc. indicating the orientation or position relationship are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation of the present invention.

[0034] As Figures 1 - 3 shown, a multifunctional device integrating water pollution treatment and wetland landscape includes a power boat 1, an ecological floating island 2, and a water treatment device. The power boat 1 is used to carry the water treatment device and the ecological floating island 2, and its power source is a solar photovoltaic cell and a storage battery. The power boat 1 is fixedly connected to the ecological floating island 2. The ecological floating island 2 has a landscape beautification function and presents a stepped shape as a whole. Appropriate aquatic plants and flowers are selected according to the water treatment requirements. A water treatment device is also provided on the power boat 1, and the water treatment device is hidden inside the ecological floating island 2.

[0035] The water treatment equipment includes a flocculation sedimentation tank 7. A ring 3 is fixedly arranged outside the flocculation sedimentation tank 7. The bottom end of the flocculation sedimentation tank 7 is fixedly connected to a power boat 1 through a support platform 8. The support platform 8 is hollow inside and communicated with the flocculation sedimentation tank 7. The support platform 8 is connected to a sediment collection tank 9 through a fifth connecting pipe 18. The side of the flocculation sedimentation tank 7 is connected to an AO biochemical tank 10 through a first connecting pipe 11. The AO biochemical tank 10 is connected to a biological filter tank 13 through a second connecting pipe 12. The biological filter tank 13 is connected to a secondary sedimentation tank 15 through a third connecting pipe 14. The secondary sedimentation tank 15 is connected to the sediment collection tank 9 through a fourth connecting pipe 16. A water outlet pipe 6 and a floating island water supply pipe 35 are also connected to the side of the secondary sedimentation tank 15. A monitoring probe 5 is arranged inside the water outlet pipe 6. The monitoring probe 5 is arranged at the connection of the water outlet pipe 6 and the secondary sedimentation tank 15. When the monitoring probe 5 detects that the water quality meets the standard, it can directly control the water outlet pipe 6 to discharge the treated water. When it detects unqualified water quality, the water outlet pipe 6 is closed. The floating island water supply pipe 35 conveys the tail water treated by the secondary sedimentation tank 15 to the ecological floating island for secondary purification.

[0036] The AO biochemical tank 10 utilizes the action of activated sludge microorganisms to carry out anoxic, anaerobic, and aerobic reactions to remove organic matter, nitrogen, and phosphorus in the wastewater, achieving the purpose of purifying the sewage. The secondary sedimentation tank 15 is communicated with the floating island water supply pipe 35 to lead the secondary-treated sewage to the ecological floating island 2 for further purification, and then discharge it after purification.

[0037] The biological filter tank 13 is to place a certain amount of filter media in the filter tank. When the waste gas filters from top to bottom through the filter media, the waste gas continuously contacts the filter media, so that microorganisms can reproduce and grow on the surface of the filter media to form a biological membrane. The biological membrane is an ecological membrane system composed of various microorganisms. Microorganisms absorb pollutants from the waste gas as nutrients and can obtain the energy required for survival during the metabolic process, and then form a new microbial community.

[0038] A monitoring probe 5 is arranged outside the water inlet pipe 4. The monitoring probe 5 is used for real-time online monitoring of raw water and effluent data. The monitoring indicators include: pH, EC, TDS, DO, ORP, COD, nitrogen, phosphorus, etc.

[0039] Such as Figures 4 - 5As shown, the flocculation sedimentation tank 7 is hollow inside, and a cover body 17 is provided at the top. A water inlet pipe 4 is provided on the cover body 17. An installation seat 19 is rotatably provided on the cover body 17 above the flocculation sedimentation tank 7. A telescopic cylinder 22 is fixedly provided on the installation seat 19. Telescopic rods 23 are also fixedly provided at both ends of the telescopic cylinder 22 on the installation seat 19. A cross bar 20 is fixedly provided above the inside of the flocculation sedimentation tank 7. A first gear 24 is rotatably provided on the cross bar 20. A round hole is opened inside the first gear 24, and a limiting block 26 is also provided at the position of the internal round hole on the first gear 24. A sliding rod 21 is slidably provided up and down at the position of the internal round hole of the first gear 24 on the cross bar 20. A sliding groove 25 is provided on the sliding rod 21, and the sliding groove 25 is slidably connected with the limiting block 26. The output end of the telescopic cylinder 22 and the extending end of the telescopic rod 23 are both fixedly connected to the top end of the sliding rod 21. A second gear 27 is also rotatably provided on the cross bar 20. The second gear 27 is meshed and driven with the first gear 24. A first motor 28 is connected to the second gear 27, and the first motor 28 is fixedly connected with the cross bar 20.

[0040] The bottom end of the sliding rod 21 is rotatably connected with a baffle 29. A plurality of holes 30 are respectively opened on both baffle plates 29. The sliding rod 21 and the two baffle plates 29 are both connected through a rotating shaft. A third gear 32 and a fourth gear 31 are respectively connected to the two rotating shafts. The third gear 32 is meshed and driven with the fourth gear 31. A fifth gear 33 is also rotatably provided on the sliding rod 21. The fifth gear 33 is meshed and driven with the third gear 32. A second motor 34 is connected to the fifth gear 33, and the second motor 34 is fixedly connected with the sliding rod 21.

[0041] As Figures 6 - 7 shown, an inclined platform 801 is provided at the bottom of the hollow part inside the support platform 8. On both sides above the inclined platform 801 inside the support platform 8, a limiting rod and a threaded rod 802 are respectively fixedly provided. The limiting rod and the threaded rod 802 are both parallel to the inclined platform 801 and are in an inclined installation state. One end of the threaded rod 802 is connected with a third motor, and the third motor drives the threaded rod 802 to rotate. The third motor is fixedly connected with the support platform 8. A first scraping plate 803 is fitted on the threaded rod 802 and the limiting rod. The bottom end of the first scraping plate 803 is rotatably connected with a second scraping plate 804. By providing a second motor 34 to drive the second scraping plate 804 to rotate on the first scraping plate 803, a sewage discharge port 805 is provided at the bottom end of the inclined platform 801 inside the support platform 8. The sewage discharge port 805 is communicated with the fifth connecting pipe 18.

[0042] In use, the power boat 1 is controlled to move to the water area to be treated. After moving to the designated water area, the water inlet pipe 4 is controlled to pump water into the flocculation sedimentation tank 7. The polluted water source flows into the flocculation sedimentation tank 7 through the water inlet pipe 4 for flocculation treatment inside. The flocculant can be put into the feed hole on the cover body 17. After the flocculant is put in, the telescopic cylinder 22 is controlled to extend to lower the sliding rod 21 to an appropriate position. The first motor 28 is started to drive the second gear 27 to rotate. The second gear 27 drives the first gear 24 to rotate. The limiting block 26 is slidably connected to the chute 25 on the sliding rod 21. The sliding rod 21 can slide up and down inside the first gear 24. At the same time, when the sliding rod 21 stops sliding up and down, the limiting block 26 limits the chute 25 so that the sliding rod 21 rotates synchronously with the first gear 24. During the rotation of the sliding rod 21, the two baffles 29 are in the vertically downward state. The rotation of the sliding rod 21 drives the baffles 29 to rotate, stirring the liquid in the flocculation sedimentation tank 7 to enable rapid flocculation. After the flocs settle, the second motor 34 is started to slowly rotate the two baffles 29 to fully unfold them. The two baffles 29 form a circular plate, forming a partition layer in the flocculation sedimentation tank 7 to isolate the sediment at the bottom end of the flocculation sedimentation tank 7. At this time, the upper-layer sewage in the flocculation sedimentation tank 7 is pumped into the AO biochemical tank 10 through the first connecting pipe 11 for treatment.

[0043] The sediment in the sedimentation area at the bottom end of the flocculation sedimentation tank 7 falls onto the inclined platform 801 in the support platform 8. The inclined platform 801 arranged obliquely facilitates the concentration of the sediment to the sewage outlet 805. The third motor is controlled to rotate the threaded rod 802, and the second scraper 804 is rotated to be horizontal with the first scraper 803 and fixed. At this time, the second scraper 804 contacts the inclined platform 801. The rotation of the threaded rod 802 drives the first scraper 803 to move downward along the inclined platform 801, scraping the sediment accumulated on the inclined platform 801 to the sewage outlet 805. When the first scraper 803 moves upward, the second scraper 804 is controlled to rotate a certain angle so that its bottom end does not contact the inclined platform 801, preventing the second scraper 804 from scraping the remaining sediment on the inclined platform 801 back. Subsequently, the fifth connecting pipe 18 is controlled to pump the sediment at the sewage outlet 805 to the sediment collection tank 9 for collection.

[0044] The sewage treated in the AO biochemical tank 10 is then treated successively through the biological filter tank 13 and the secondary sedimentation tank 15. The internal structure of the secondary sedimentation tank 15 is the same as that of the flocculation sedimentation tank 7. The up-to-standard sewage treated by the secondary sedimentation tank 15 is discharged through the water outlet pipe 6. The sediment generated by the secondary sedimentation tank 15 is pumped into the sediment collection tank 9 through the fifth connecting pipe 18 for collection.

[0045] This device is also equipped with a software part. The software part includes a boat control system for controlling the movement of the power boat 1 on the water surface, a water treatment control system for controlling the operation of the water treatment equipment, and a data acquisition system for collecting the water quality information collected by the monitoring probe 5.
