Description

Technical Field

[0001] This invention relates to the field of cyanobacteria control technology, and in particular to a novel in-situ cyanobacteria bloom control system. Background Technology

[0002] Cyanobacteria, as common planktonic organisms in freshwater ecosystems, are prone to explosive proliferation in eutrophic waters, forming thick "algal blooms." On the one hand, they densely cover the water surface, blocking sunlight and causing aquatic plants to die off due to hindered photosynthesis, disrupting the basic links of the aquatic food chain, leading to oxygen depletion and death of aquatic organisms such as fish and shrimp, and causing ecological chain disruption. On the other hand, some cyanobacteria (such as Microcystis) secrete highly toxic microcystin toxins. These toxins not only pollute drinking water sources and may damage the liver and nervous system after human ingestion, posing a serious threat to residents' health, but also lead to reduced aquaculture production and decreased aesthetic appeal of landscape water bodies, directly affecting the development of the surrounding tourism and fishery economy.

[0003] The current mainstream in-situ cyanobacteria treatment system mainly consists of solar panels, aeration devices, and ecological floating islands. The aeration devices increase dissolved oxygen content in the water by oxygenating the bottom layer, improving the anaerobic environment, inhibiting the growth of cyanobacteria (which prefer anaerobic environments), and promoting the activity of aerobic microorganisms, accelerating the degradation of cyanobacteria residues, and breaking down water stratification. The ecological floating islands are built on the water surface and planted with aquatic economic plants. The aquatic plants absorb nutrients such as nitrogen and phosphorus from the water through their roots, reducing the nutrient supply to cyanobacteria. At the same time, the plant leaves block sunlight, reducing the light intensity in the surface water and inhibiting cyanobacteria photosynthesis. The roots can also intercept cyanobacteria and provide an attachment carrier for microorganisms, assisting in the degradation of pollutants, forming a synergistic purification system of "plants-microorganisms-water".

[0004] However, existing in-situ cyanobacteria control systems have significant limitations: their core effectiveness is highly dependent on the metabolic activity of microorganisms and the growth cycle of plants—microbial degradation efficiency is greatly affected by environmental factors such as temperature and dissolved oxygen, while plant absorption of nutrients requires a certain growth time; both are "slow-regulation" control methods. Therefore, during cyanobacterial blooms (when cyanobacterial biomass increases exponentially in a short period), existing systems cannot quickly reduce the total amount of cyanobacteria and inhibit its spread, ultimately still requiring manual removal (such as mechanical dredging vessels and manual nets) for emergency treatment, resulting in high costs and low efficiency. Summary of the Invention

[0005] The purpose of this invention is to solve the problems mentioned in the background art by proposing a novel in-situ treatment system for cyanobacterial blooms.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A novel in-situ treatment system for cyanobacterial blooms includes a floating vessel, an ecological floating island, and an interception and dredging device. The floating vessel is fixedly equipped with solar photovoltaic panels, a battery, an aeration device, and a water circulation device. The ecological floating island is assembled from multiple floating plates and is arranged around the floating vessel and fixed to the floating vessel through connectors. The interception and salvage device includes an interception trough and a conveyor belt. The top circumferential part of the interception trough is provided with a lifting part, which is arranged around the top edge of the interception trough. The bottom of the lifting part is sealed and fixed to the top edge of the interception trough. A lifting device is provided inside the lifting part to control the lifting of the lifting part. The bottom of the interception trough is provided with a water collection chamber and a blue-green algae chamber at both ends, and the water collection chamber and the blue-green algae chamber are connected to the inner cavity of the interception trough. The conveyor belt is fixedly installed in the inner cavity of the interception trough, and the material conveying direction of the conveyor belt is set to convey from the water collection chamber side to the blue-green algae chamber side. The surface of the conveyor belt is covered with water-permeable holes. A guide plate is fixedly installed on the inner wall of the cyanobacteria chamber facing the water collection chamber. The top of the guide plate extends towards the conveyor belt, and a material brush is fixedly installed on the top of the guide plate. The bristles of the material brush are in close contact with the lower surface of the conveyor belt.

[0007] As a further embodiment of the present invention: a suction pump is fixedly installed inside the cyanobacteria chamber, the inlet end of the suction pump is connected to the inner cavity of the cyanobacteria chamber, and the outlet end of the suction pump is connected to a discharge pipe. The end of the discharge pipe away from the suction pump is used to connect to an external cyanobacteria collection device. The suction pump is used to transport the cyanobacteria collected in the cyanobacteria chamber to the external cyanobacteria collection device through the discharge pipe. A water pump is fixedly installed inside the water collection chamber. The inlet of the water pump is connected to the inner cavity of the water collection chamber, and the outlet of the water pump is connected to a drain pipe. The end of the drain pipe away from the water pump is connected to an external water body, which is used to discharge the water collected in the water collection chamber into the external water body through the water pump.

[0008] As a further aspect of the present invention: the conveyor belt is set at an inclination, with the end of the conveyor belt near the cyanobacteria cavity being higher than the end near the water collection cavity; The bottom surface of the interception tank is set at an inclination, with the end of the bottom surface of the interception tank near the water collection chamber being lower than the end near the cyanobacteria chamber.

[0009] As a further aspect of the present invention: multiple scrapers are evenly distributed on the surface of the conveyor belt along the conveying direction, and the scrapers are perpendicular to the surface of the conveyor belt and fixedly connected to it. The scraper is covered with water-permeable holes, the overall height of the material brush is greater than the height of the scraper, and the bristles of the material brush can cover the surface of the scraper.

[0010] As a further embodiment of the present invention: the lifting device includes a lifting plate and an electrically controlled lifting rod, the bottom of the electrically controlled lifting rod is fixedly connected to the top of the interception groove, the top of the electrically controlled lifting rod is fixedly connected to the bottom surface of the lifting plate, the top surface of the lifting plate is fixedly connected to the top inner wall of the lifting part, and the lifting plate and the lifting part are fixed as an integral structure. The lifting part is made of elastic rubber material, and the entire lifting part is covered by the outside of the lifting device.

[0011] As a further aspect of the present invention: the aeration device includes an aeration pump, an aeration pipe and an aeration head. The aeration pump is fixedly installed on a floating vessel, the aeration head is located in the lower layer of the water body, one end of the aeration pipe is connected to the aeration pump, and the other end extends to the lower layer of the water body and is connected to the aeration head.

[0012] As a further embodiment of the present invention: the water circulation device includes a circulating water pump, an inlet pipe and an outlet pipe, the circulating water pump is fixedly installed on the floating boat, one end of the inlet pipe is connected to the circulating water pump, and the other end extends to the bottom of the water body; One end of the outlet pipe is connected to the circulating water pump, and the other end extends to the surface of the water body.

[0013] As a further aspect of the present invention, filters are fixedly installed at the ends of the inlet pipe and the outlet pipe.

[0014] As a further aspect of the present invention: multiple interception and salvage devices are provided, and the multiple interception and salvage devices are arranged around the outer periphery of the ecological floating island, and the bottom of each interception and salvage device is connected and fixed to the floating plate of the ecological floating island through a connector.

[0015] As a further aspect of the present invention: the floating vessel floats on the water surface and rises and falls synchronously with the water level. Cables are connected to the four sides of the floating vessel. One end of the cable is fixedly connected to the hull of the floating vessel, and the other end of the cable is connected to a fixed anchor on the bottom of the water or a fixed pile on the shore for positioning the floating vessel.

[0016] Compared with existing technologies, the advantages of this invention are: 1. By adding an interception and retrieval device with an adjustable lifting section, the intelligent switching of the treatment mode is realized: Normally, the lifting section is above the water surface, which does not interfere with water flow and the normal operation of the ecological floating island; when cyanobacterial blooms occur, the lifting section descends below the water surface, actively forming an interception and retrieval barrier, guiding the surface-enriched cyanobacteria into the interception tank, and separating the cyanobacteria from the water with an inclined conveyor belt with water-permeable holes and scrapers, and then transferring the cyanobacteria to an external collection device by a suction pump. This can quickly retrieve cyanobacteria and inhibit their spread, without relying on inefficient and costly manual retrieval, and overcome the limitation of existing technologies that cannot respond quickly to cyanobacterial blooms.

[0017] 2. This invention integrates a liftable interception and retrieval device with an ecological floating island, an aeration device, and a water circulation device into a single system. This system can rapidly reduce cyanobacteria biomass. At the same time, the aeration device improves dissolved oxygen, the water circulation device enhances water exchange, and the ecological floating island continuously absorbs nutrients and blocks sunlight. This synergistic approach achieves full-cycle management of "emergency response during outbreaks + stability maintenance during non-outbreaks," thus organically combining short-term symptomatic relief with long-term fundamental solutions.

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Reference Figures 1 to 9 A novel in-situ control system for cyanobacterial blooms includes a floating boat 1, an ecological floating island 2, and an interception and salvage device 3. The floating boat 1 floats on the water surface and rises and falls synchronously with the water level. The floating boat 1 is connected to fixed anchors on the bottom of the water or fixed piles on the shore by cables, thereby achieving the positioning of the floating boat 1, preventing it from drifting randomly, ensuring the stability of the entire system under the influence of waves or water flow, and providing a reliable foundation for subsequent components. It should be noted that after the cables are released, the position of the floating boat 1 in the water can be adjusted.

[0022] The floating vessel 1 is fixedly equipped with solar photovoltaic panels 4, batteries, an aeration device 6, and a water circulation device 7. The solar photovoltaic panels 4 are responsible for converting solar energy into electrical energy and storing it in the batteries, providing clean energy for the entire system and reducing operating costs. The aeration device 6 includes an aeration pump 24, an aeration pipe 25, and an aeration head 26. The aeration pump 24 is fixed to the floating vessel 1, and one end of the aeration pipe 25 is connected to the aeration pump 24, while the other end extends to the lower layer of the water and connects to the aeration head 26.

[0023] Aeration heads 26 are installed in the lower layer of the water body to increase dissolved oxygen content, improve the anaerobic environment, promote the degradation of organic matter by aerobic microorganisms, and break up water stratification by oxygenating the bottom water. The water circulation device 7 includes a circulating water pump 27, an inlet pipe 28, and an outlet pipe 29. The circulating water pump 27 is fixed to the floating vessel 1. One end of the inlet pipe 28 is connected to the circulating water pump 27, and the other end extends to the bottom of the water body. One end of the outlet pipe 29 is connected to the circulating water pump 27, and the other end extends to the surface of the water body. The circulating water pump 27 can draw oxygen-deficient water from the bottom layer to the surface, while simultaneously transporting oxygen-rich water from the surface layer to the bottom layer, enhancing water exchange between the upper and lower layers. This allows for rapid exchange between aerobic algae on the surface and anoxic water at the bottom layer, achieving a virtuous cycle, preventing nutrient accumulation, and thus reducing cyanobacteria growth at its source. Filters are installed at the ends of both the inlet pipe 28 and the outlet pipe 29 to prevent impurities from clogging the pipes and improve system reliability.

[0024] The ecological floating island 2 is assembled from multiple floating panels 8, which are arranged around the floating vessel 1 and fixed to the vessel 1 by connectors (such as hinges or plates). This modular design facilitates transportation and installation, while allowing the size of the floating island to be flexibly adjusted according to the water area. Aquatic economic plants such as reeds and water lilies are planted on the floating panels 8. The plant roots penetrate deep into the water, absorbing nutrients such as nitrogen and phosphorus, reducing the nutrient supply to cyanobacteria; the plant leaves block sunlight, reducing the light intensity in the surface water and inhibiting cyanobacteria photosynthesis; the roots also provide an attachment carrier for microorganisms, forming a synergistic purification system of "plant-microorganism-water". The fixed connection between the ecological floating island 2 and the floating vessel 1 ensures the stability of the overall structure and prevents it from disintegrating due to wind and waves.

[0025] Reference Figures 5 to 9Multiple interception and salvage devices 3 are arranged around the outer perimeter of the ecological floating island 2. The bottom of each interception and salvage device 3 is connected and fixed to the floating plate 8 of the ecological floating island 2 by a connector (such as a hinge or plate). The interception and salvage device 3 includes an interception trough 9 and a conveyor belt 10. A lifting part 11 is provided around the top periphery of the interception trough 9. The lifting part 11 is arranged around the top edge of the interception trough 9 and its bottom is sealed and fixed to the top edge of the interception trough 9.

[0026] The lifting unit 11 is equipped with a lifting device 12 for controlling the lifting of the lifting unit 11. The lifting device 12 includes a lifting plate 22 and an electrically controlled lifting rod 23. The bottom of the electrically controlled lifting rod 23 is fixedly connected to the top of the intercepting groove 9, and the top is fixedly connected to the bottom surface of the lifting plate 22. The top surface of the lifting plate 22 is fixedly connected to the inner wall of the top of the lifting unit 11, and the lifting unit 11 is made of elastic rubber material and is completely covered by the lifting device 12.

[0027] During non-cyanobacterial bloom periods, the lifting unit 11 is raised above the water surface via the electrically controlled lifting rod 23, without interfering with water flow or the normal operation of the ecological floating island. During cyanobacterial blooms (determined by regular remote sensing monitoring or by installing automatic water quality monitoring stations in the water body), the lifting unit 11 descends below the water surface, forming an active interception and retrieval barrier, guiding the surface-enriched cyanobacteria into the interception trough 9.

[0028] The bottom of the interception trough 9 is equipped with a water collection chamber 13 and a cyanobacteria chamber 14, both of which are connected to the inner cavity of the interception trough 9. The conveyor belt 10 is fixedly installed in the inner cavity of the interception trough 9 and is set in an inclined state, with the end near the cyanobacteria chamber 14 being higher than the end near the water collection chamber 13. The bottom surface of the interception trough 9 is also set in an inclined state, with the end near the water collection chamber 13 being lower, which facilitates water collection. The material conveying direction of the conveyor belt 10 is from the water collection chamber 13 side to the cyanobacteria chamber 14 side. The surface is covered with water-permeable holes, and multiple scrapers 21 are evenly distributed along the conveying direction. The scrapers 21 are perpendicular to the surface of the conveyor belt 10 and are fixedly connected. They also have water-permeable holes to improve the efficiency of cyanobacteria capture.

[0029] When the cyanobacteria-water mixture enters the interception tank 9, the conveyor belt 10 rotates and the scraper 21 pushes the cyanobacteria upward. At the same time, the water is filtered out through the water permeable holes and flows back to the water collection chamber 13, achieving the initial separation of cyanobacteria and water. The cyanobacteria are conveyed to the end by the conveyor belt 10 and fall into the cyanobacteria chamber 14.

[0030] A guide plate 15 is fixedly installed on the inner wall of the cyanobacteria chamber 14 facing the water collection chamber 13. The top of the guide plate 15 extends towards the conveyor belt 10 and a material brush 16 is fixed thereon. The bristles of the material brush 16 are in close contact with the lower surface of the conveyor belt 10, and its overall height is greater than the height of the scraper 21. The bristles can cover the surface of the scraper 21. When the conveyor belt 10 passes the material brush 16, the bristles scrape the adhering cyanobacteria into the cyanobacteria chamber 14, ensuring thorough cleaning.

[0031] A suction pump 17 is fixedly installed inside the cyanobacteria chamber 14. The inlet end of the suction pump 17 is connected to the inner cavity of the cyanobacteria chamber 14, and the outlet end is connected to the discharge pipe 18. The other end of the discharge pipe 18 is connected to an external cyanobacteria collection device (such as a collection vessel or onshore treatment facility). The suction pump 17 transports the collected cyanobacteria out through the discharge pipe 18 to achieve continuous and automated harvesting.

[0032] A water pump 19 is fixedly installed inside the water collection chamber 13. The inlet of the water pump 19 is connected to the inner cavity of the water collection chamber 13, and the outlet is connected to the drain pipe 20. The other end of the drain pipe 20 is connected to the external water body. The water pump 19 drains the water accumulated in the water collection chamber 13 back into the water body to maintain the system's water balance. The advantage of this design is that it can quickly reduce the biomass of cyanobacteria through a conveyor belt separation and pumping system, eliminating the need for manual harvesting and greatly improving the efficiency of cyanobacteria harvesting.

[0033] In summary, during normal non-cyanobacterial bloom periods, the lifting unit 11 remains above the water surface, the solar photovoltaic panel 4 continuously charges the battery, the aeration device 6 periodically aerates the bottom of the water, the water circulation device 7 operates intermittently to break up water stratification, and the plants on the ecological floating island 2 continuously absorb nutrients and block sunlight. These three elements work together to achieve water ecological restoration and cyanobacterial prevention. When a cyanobacterial bloom is detected, the interception and retrieval device 3 is activated, the lifting unit 11 descends, and then the conveyor belt 10, suction pump 17, and water pump 19 start simultaneously. The surface cyanobacteria are intercepted and enter the interception tank 9. After being separated by the conveyor belt 10 and scraper 21, the water is transported to the cyanobacterial chamber 14, and then transferred by the suction pump 17 to the external collection device. The separated clean water is discharged back into the water body by the water pump 19. The entire process achieves rapid cyanobacterial retrieval and suppression of its spread. At the same time, the ecological floating island, aeration, and water circulation devices work continuously to achieve dual treatment of "emergency retrieval + ecological restoration," achieving an organic combination of short-term symptomatic relief and long-term fundamental treatment.

[0034] To further clarify, the aforementioned fixed connection should be interpreted broadly unless otherwise explicitly specified and limited. For example, it may be welding, gluing, or integral molding, or other conventional methods well known to those skilled in the art.

[0035] The steps involved in this application are as follows: S1: Connect the floating vessel 1 to the underwater anchor or shore anchor via cables to complete the positioning; assemble multiple floating panels 8 into an ecological floating island 2, surround the outer perimeter of the floating vessel 1 and fix it with connectors; deploy multiple interception and salvage devices 3 along the outer perimeter of the ecological floating island 2, and connect and fix the bottom of each device to the floating panel 8; at the same time, check the circuit and mechanical connections of the solar photovoltaic panel 4, battery, aeration device 6, water circulation device 7 and interception and salvage device 3, and start the system after ensuring that there are no faults, and the battery begins to store the electrical energy converted from solar energy.

[0036] S2: Routine ecological maintenance during non-cyanobacterial bloom periods (S21-S23) S21: Control the electric lifting rod 23 of the interception and salvage device 3 to raise the lifting part 11 to a position above the water surface, so as to avoid interfering with the normal flow of water and the operation of the ecological floating island 2; the aquatic plants planted on the floating plate 8 absorb nutrients such as nitrogen and phosphorus in the water through their roots, and their leaves block the surface light, inhibiting the photosynthesis of blue-green algae, while providing a carrier for microorganisms to attach and assist in the degradation of pollutants. S22: The aeration pump 24 of the aeration device 6 is started at regular intervals, and air is delivered to the aeration head 26 in the lower layer of the water body through the aeration pipe 25 to oxygenate the bottom water body, improve the anaerobic environment, promote the activity of aerobic microorganisms, accelerate the degradation of organic matter, and break up the water stratification. S23: Intermittently start the circulating water pump 27 of the water circulation device 7, draw oxygen-deficient water from the bottom of the water body through the inlet pipe 28, and transport it to the surface of the water body through the outlet pipe 29; at the same time, the oxygen-rich water on the surface naturally sinks, realizing the exchange of water between the top and bottom, avoiding the accumulation of nutrients at the bottom, and reducing the conditions for cyanobacteria reproduction from the source.

[0037] S3: Emergency Interception and Salvage during Blue-Green Algae Outbreaks (S31-S36) S31: When a cyanobacterial bloom is detected, the electric lifting rod 23 is retracted, which drives the lifting part 11 to descend below the water surface, forming an interception and salvage barrier around the ecological floating island 2, and guiding the surface-enriched cyanobacterial water mixture into the interception tank 9. S32: Start the conveyor belt 10 in the interception tank 9 and make it run in the direction of "water collection chamber 13 → blue-green algae chamber 14"; at the same time, start the suction pump 17 and the water pump 19 to prepare for the transport of blue-green algae and the discharge of accumulated water. S33: After the cyanobacteria-water mixture enters the interception tank 9, the scraper 21 on the surface of the inclined conveyor belt 10 pushes the cyanobacteria upward. The water is filtered out through the water-permeable holes on the conveyor belt 10 and the scraper 21, and collects along the bottom surface of the inclined interception tank 9 into the water collection chamber 13, thus achieving the initial separation of cyanobacteria and water. S34: When the conveyor belt 10 transports the cyanobacteria to the end near the cyanobacteria cavity 14, the cyanobacteria fall into the cyanobacteria cavity 14 under the action of gravity; at the same time, the lower surface of the conveyor belt 10 passes the material brush 16 at the top of the guide plate 15, and the brush bristles adhere to the surface of the conveyor belt 10 and the scraper 21, thoroughly scraping the adhered cyanobacteria into the cyanobacteria cavity 14 to avoid residue. S35: The suction pump 17 draws out the cyanobacteria collected in the cyanobacteria chamber 14 through the feed end and transports it to the external cyanobacteria collection device such as a collection ship or onshore treatment facility through the discharge pipe 18 to achieve continuous transfer of cyanobacteria; during the process, the conveyor belt 10 is kept running to ensure continuous salvage. S36: The water pump 19 in the water collection chamber 13 draws up the accumulated water and discharges it back to the external water body through the drain pipe 20 to maintain the water balance of the system; at the same time, the aeration device 6 and the water circulation device 7 continue to work to continuously improve the water environment and help inhibit the spread of blue-green algae.

[0038] S4: Once the cyanobacterial bloom is under control and the monitoring data returns to normal, shut down the conveyor belt 10, suction pump 17, and water pump 19; control the extension of the electrically controlled lifting rod 23 to raise the lifting part 11 to a position above the water surface, and the system returns to the routine maintenance state during the non-outbreak period, waiting for the next monitoring response.

[0039] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
