Description

Technical Field

[0001] This utility model relates to the field of algae purification and filtration technology, specifically to a long-lasting algae purification and filtration system. Background Technology

[0002] Algal bloom control is an international challenge. Currently, the main algal control measures are as follows:

[0003] 1. Ultrasonic algae removal

[0004] Certain frequencies of ultrasound can inhibit algal growth. Algal cells vibrate in response to appropriate frequencies of ultrasound, causing the cytoplasm to separate from the nucleus, thus damaging the nucleus and causing the algae to die from the pressure. Different algae have varying sensitivities to different ultrasound frequencies, and their adaptability to ultrasound also varies in different seasons. Continuously adjusting the sound wave frequency is key to long-term algal control. Advantages: Ultrasonic algae removal is a widely used technology that effectively prevents the growth of green and blue-green algae; it is harmless to other plants and animals, has real-time water quality tracking capabilities, and can predict algal blooms. Disadvantages: Ultrasonic waves of a certain frequency are often only effective against specific algae species, limiting its application in waters with diverse algal populations. Furthermore, ultrasound cannot completely inhibit algal growth and is not suitable for water bodies where algae grow rapidly.

[0005] 2. Chemical control

[0006] Chemical agents are used to control algae, causing algal cells to lose activity and die. Commonly used algaecides include copper sulfate, copper complex, bleaching powder, and chlorine dioxide. Advantages: Fast and thorough algae control; quickly clarifies the water and eliminates algal blooms. Disadvantages: After treatment, the lack of algae in the water easily leads to oxygen depletion in fish and shrimp; the treatment is not long-lasting; the effects of the agent wear off, and blue-green algae recur.

[0007] 3. Aeration

[0008] Lakes must maintain healthy dissolved oxygen levels, which help bacteria decompose decaying vegetation and other nutrients in the water. Bacterial decomposition is divided into aerobic and anaerobic decomposition, with aerobic decomposition requiring oxygen. Decomposition becomes more vigorous when the dissolved oxygen concentration in the water approaches saturation. Aeration uses oxygenation to accelerate biodegradation, primarily slowing down eutrophication and preventing rapid algal growth, rather than killing algae. Advantages: Environmentally friendly. Disadvantages: Weak algal suppression; only effective in waters with mild algal blooms; less effective in severe blooms; high maintenance and labor costs.

[0009] The aforementioned conventional methods for treating algal blooms all have limitations and cannot provide long-term and efficient control. Utility Model Content

[0032] To better explain this utility model, the main contents of this utility model are further illustrated below with reference to specific embodiments, but the contents of this utility model are not limited to the following embodiments.

[0033] like Figure 1 As shown, this utility model discloses a long-term algae purification and filtration system, comprising a water collection component 1, a water pump 2, a water collection tank 5, a heating tank 7, an aeration sedimentation tank 10, and a cooling tank 13, which are connected in sequence by pipes. The outlet of the cooling tank 13 is connected to the water area to be treated. The algae mainly refer to cyanobacteria, and algal blooms in freshwater areas are primarily caused by cyanobacteria, especially Microcystis.

[0034] A water collection assembly 1 is laid in the water body to be treated (river, lake, etc.) to collect algae-rich water from the surface. The water collection assembly 1 consists of multiple unit water collectors 102 and a water collection pipe network 101 located at the bottom of the unit water collectors 102. The water collection pipe network 101 is laid at the bottom of the water body to be treated (river, lake, etc.). The unit water collectors 102 are used to collect algae-rich water from the surface and are arranged at various points on the water surface. The amount of water collected by a single unit water collector 102 moving up and down once is V0, and the time taken is t. The number of unit water collectors 102 in the water body is n.

[0035] The bottom opening of the unit water collector 102 is connected to the water collection network 101 via a PVC pipe 1024. The water collection network 101 connects all the unit water collectors 102 and converges them to the same outlet. The PVC pipe 1024 is a water pipe with high temperature resistance (100℃) and good deformation resistance. Figure 2 and Figure 3 As shown, the unit water collector 102 consists of a circulating telescopic water intake ring 1021, a cylinder 1022, and a filter screen 1023. The cylinder 1022 is a cylindrical structure open at both ends, made of waterproof and corrosion-resistant PVC material, with its bottom opening matching the size of the opening in the PVC pipe 1024. The circulating telescopic water intake ring 1021 is located at the top of the cylinder 1022 and can move up and down cyclically to collect algae-rich water from the water surface. During use, the top of the circulating telescopic water intake ring 1021 is above the water surface when extended and below the water surface when retracted. The cyclical up-and-down movement of the circulating telescopic water intake ring 1021 accelerates the collection efficiency of algae-rich water. The filter screen 1023 is located at the bottom of the cylinder 1022 and is used to filter out large-volume debris that the unit water collector 102 may accidentally collect, preventing blockage of the PVC pipe 1024 and the water collection network 101. The circulating telescopic water intake ring 1021 consists of a telescopic ring 1021A, a spring 1021B, and a flexible waterproof cloth 1021C. Springs 1021B are evenly distributed on the annular end face of the top of the cylinder 1022. One end of each spring is fixedly connected to the cylinder 1022, and the other end is connected to the telescopic ring 1021A. The flexible waterproof cloth 1021C has an annular structure. Its inner ring edge is sealed to the annular end face of the top of the cylinder 1022, and its outer ring edge is fixedly connected to the telescopic ring 1021A. Springs 1021B provide support for the telescopic ring 1021A, and the telescopic ring 1021A drives the flexible waterproof cloth 1021C to move up and down.

[0036] The telescopic ring 1021A can be driven to move up and down reciprocally by a driving device. The driving device includes a power source, a connecting rod, and a guiding mechanism. The power source can be an electric push rod, a pneumatic cylinder, or a hydraulic cylinder, and is located on the outside of the cylinder 1022. The output end of the power source is connected to the telescopic ring 1021A via the connecting rod, which is arranged along the axial direction of the cylinder 1022. The connecting rod transmits the linear reciprocating motion of the power source to the telescopic ring 1021A, causing the telescopic ring 1021A to drive the spring 1021B and the flexible waterproof cloth 1021C to achieve up and down telescopic movement. The guiding mechanism includes a guide rail or a guide groove, which is set on the inner or outer wall of the cylinder 1022. It guides the movement of the telescopic ring 1021A, ensuring stable up and down movement of the telescopic ring 1021A along the axial direction of the cylinder 1022 and preventing deviation or jamming. The power source of the drive unit can be controlled by the controller to start, stop, and move at its frequency, thereby enabling the cyclic retractable water intake ring 1021 to automatically move up and down in a cycle under set time or water quality conditions, improving the water intake efficiency and uniformity of algae-rich water. The controller is powered by the solar panel 8.

[0037] Operating principle of unit water collector 102: When the circulating telescopic water intake ring 1021 moves downward to below the water surface, the algae-rich water on the surface of the water body enters the cylinder 1022. After the large volume of garbage is filtered by the filter screen 1023, the algae-rich water enters the water collection network 101 through the PVC pipe 1024. When the circulating telescopic water intake ring 1021 moves upward to above the water surface, the collection of algae-rich water stops.

[0038] The suction pump 2 is connected to the outlet of the water collection assembly 1 and is used to pump water from the water collection assembly 1.

[0039] The water collection tank 5 is used to store the algae-rich water collected by the water collection assembly 1. The water collection tank 5 is connected to the outlet of the water suction pump 2, and the water suction pump 2 draws water from the water collection assembly 1 into the water collection tank 5. When the water level in the water collection tank 5 reaches a predetermined liquid level, the water collection assembly 1 stops collecting the algae-rich water.

[0040] A first stop valve 4 and a flow meter 3 are installed on the pipeline between the water pump 2 and the water collection tank 5. The first stop valve 4 is an electrically adjustable valve that can close / open the water pipe passage. The flow meter 3 measures the flow rate through the cross-section of the water pipe. When the flow rate through the flow meter 3 reaches nV0 in a single operation, the first stop valve 4 is closed. After a time t, the first stop valve 4 is opened, and the cycle repeats. The first stop valve 4 is powered by a solar panel 8.

[0041] The second stop valve 6, located at the outlet of the water collection tank 5, is an electrically operated regulating valve that can close / open the water pipe passage between the water collection tank 5 and the heating tank 7. When the water level in the water collection tank 5 reaches the predetermined level, the second stop valve 6 is opened, and after the water in the water collection tank 5 is drained, the second stop valve 6 is closed. The second stop valve 6 is powered by the solar panel 8.

[0042] The heating tank 7 is connected to the outlet of the water collection tank 5 via a pipe. Water from the water collection tank 5 enters the heating tank 7 through the pipe. The heating tank 7 is used to heat the algae-rich water. Utilizing the temperature sensitivity of algae, the water is heated to a predetermined temperature and maintained at a high temperature for a certain period of time to kill most of the harmful algae. The predetermined temperature and the holding time can be adjusted to adapt to different algae removal requirements. For example, if the algae is cyanobacteria, it can be heated to above 60°C and held for at least 30 minutes, or heated to above 80°C and held for at least 10 minutes. The heating tank 7 is also electrically connected to a solar panel 8, which provides heat energy to the heating tank 7. Specifically, the solar panel is electrically connected to the electric heating element in the heating tank 7, supplying power to the electric heating element.

[0043] The third stop valve 9 is located at the outlet of the heating pool 7 and can close / open the water pipe passage between the heating pool 7 and the aeration sedimentation tank 10. The third stop valve 9 is an electric regulating valve powered by the solar panel 8.

[0044] Solar panel 8 collects solar energy to generate electricity to power various electrical drive components in the device. Solar panel 8 is also equipped with a battery to store excess electricity when there is sufficient sunlight and to supplement the device's power needs when there is insufficient sunlight.

[0045] The aeration sedimentation tank 10 serves as both an aeration and sedimentation tank. It is connected to the outlet of the heating tank 7 via a pipe and is used for aeration and sedimentation of the water. The aeration sedimentation tank 10 is preferably a nano-aeration sedimentation tank, which uses a nano bubble generator or nano aeration device to produce bubbles with extremely small particle sizes (usually between tens and hundreds of nanometers).

[0046] After the water treated in heating tank 7 is introduced into aerated sedimentation tank 10, air is added to fully dissolve oxygen. Turbulence and convection promote the reproduction of microorganisms in the wastewater. Through the metabolism of anaerobic and aerobic microorganisms, the algal organic matter treated in heating tank 7 is decomposed into smaller impurity particles, gradually becoming easily settled sludge. Finally, through sludge sedimentation and the movement of fluids within the tank, the formed sludge settles into the lower sedimentation tank, and the sludge is periodically cleaned.

[0047] The trash rack 11 is installed at the outlet of the aeration sedimentation tank 10. It is used to filter the water in the sedimentation tank and block algae residue. It needs to be cleaned regularly to ensure that the water path is unobstructed.

[0048] Cooling tank 13 is connected to the outlet of aeration sedimentation tank 10 via a pipe to receive water purified by aeration and sedimentation. Cooling tank 13 is equipped with a temperature measuring instrument. When the water temperature in the tank drops to the same temperature as the water body, the purified water is discharged back into the water body.

[0049] The fourth stop valve 12 is installed on the pipe between the trash rack 11 and the cooling pool 13. It discharges the water after filtering algae into the cooling pool 13 by opening and closing. The fourth stop valve 12 is powered by the solar panel 8.

[0050] The fifth stop valve 14 is located at the outlet of the cooling pool 13. When the valve is opened, the water in the cooling pool 13 can be discharged back into the water area. The fifth stop valve 14 is powered by the solar panel 8.

[0051] Water pumps can be installed on the pipelines between the water collection tank 5 and the heating tank 7, the heating tank 7 and the aeration sedimentation tank 10, the aeration sedimentation tank 10 and the cooling tank 13, and the cooling tank 13 and the water area to be treated, so that water can be pumped into the next treatment unit in sequence. Alternatively, the height of each treatment unit can be reduced in sequence, and the water can be discharged directly to the next treatment unit through the outlet. For example, the outlet of the water collection tank 5 is set at the bottom of the water collection tank 5, and the height of the heating tank 7 is set below the outlet of the water collection tank 5.

[0052] A long-term algae purification and filtration method, implemented through the aforementioned long-term algae purification and filtration system, includes the following steps:

[0053] 1) Collect algae-rich water from the surface of the water body to be treated through water collection component 1.

[0054] Specifically, the first stop valve 4 and the suction pump 2 are opened. The circulating telescopic water intake ring 1021 of the unit water collector 102 moves up and down cyclically to collect algae-rich water from the water surface. Large debris in the unit water collector 102 is filtered through the filter screen 1023. The algae-rich water enters the water collection network 101 through the PVC pipe 1024 at the bottom of the unit water collector 102. From the outlet of the water collection network 101, the suction pump 2 draws water into the water collection tank 5. When the water level in the water collection tank 5 reaches the predetermined level, the water collection assembly 1 stops collecting the algae-rich water and closes the first stop valve 4 and the suction pump 2. The predetermined level can be calculated using the flow rate measured by the flow meter 3.

[0055] 2) Heat the algae-rich water to a set temperature and maintain it for a set time to kill most of the harmful algae; the set temperature and set time are determined by the types of algae in the water to be treated.

[0056] Specifically, the second stop valve 6 is opened to discharge the water in the collection pool 5 into the heating pool 7, and the water in the heating pool 7 is heated to a predetermined temperature and maintained for a certain period of time to kill harmful algae.

[0057] 3) Aerate, settle, and filter the heated water.

[0058] Specifically, the third stop valve 9 is opened to discharge the water that has been treated and cooled to a certain temperature in the heating tank 7 into the aeration sedimentation tank 10. Air is then added to the aeration sedimentation tank 10 to aerate and settle the water. The treated water in the heating tank 7 needs to be cooled to promote the reproduction of microorganisms in the aeration sedimentation tank 10.

[0059] 4) Cool the filtered water to ambient temperature before discharging it into the water body.

[0060] Specifically, the fourth stop valve 12 is opened, and the water in the aeration sedimentation tank 10 is filtered through the trash rack 11 and discharged into the cooling tank 13. When the water temperature in the cooling tank 13 drops to the same temperature as the water body, it is discharged into the water body.

[0061] This invention employs a dual treatment process of heating inactivation and aeration sedimentation. Heating rapidly inactivates algal cells, disrupting their physiological structure; subsequent aeration sedimentation further degrades algal residues and organic pollutants (such as COD and ammonia nitrogen). Combined with nano-aeration technology, dissolved oxygen efficiency is significantly improved, microbial metabolism is enhanced, and algae are completely removed, preventing secondary growth. The cooling tank of this invention uses a temperature measuring instrument for real-time monitoring to ensure that the effluent temperature is consistent with the water temperature, preventing thermal shock damage to the ecosystem.

[0062] This invention employs a circulating telescopic water intake ring, controlled by a drive device to move the ring up and down. A flexible waterproof fabric adjusts accordingly, dynamically adapting to water level fluctuations (such as tides and rainfall) to continuously capture surface algae-rich water (algae accumulation layer) and avoid interference from bottom sediments. The distributed unit water collector and pipe network layout significantly improves the algae-rich water collection coverage and reduces stagnant water areas. The flow meter is linked to multi-stage stop valves (first to fifth stop valves) to precisely control the water flow rate and start / stop of each treatment unit, preventing backflow or pressure imbalance and reducing manual intervention.

[0063] This utility model adopts a modular design, and components such as unit water collectors and aeration sedimentation tanks can be disassembled and maintained independently, reducing the risk of downtime due to malfunctions.

[0064] This invention does not use chemical agents, but relies on physical heating and biological aeration for degradation, thus avoiding the harm of chemical algaecides to aquatic organisms and meeting the requirements of ecological restoration.

[0065] This invention has a wide range of applications, suitable for eutrophic waters such as lakes, reservoirs, and aquaculture ponds, and is especially suitable for large-scale treatment of blue-green algae and green algae blooms. This invention uses solar panels to directly power the heating tank, electric stop valve, and water pump, combined with battery energy storage, enabling off-grid operation and reducing energy costs. Furthermore, the use of solar power reduces electricity expenses, and the heating-based algae removal method is more cost-effective than ultraviolet or ozone treatment; the system's automation reduces the frequency of manual inspections.

[0066] In summary, this utility model system, through a closed-loop design encompassing efficient algae removal, purification, temperature control, and water reuse, combined with solar-powered operation, adaptive water collection, and intelligent control technologies, achieves long-term algae control and aquatic ecological restoration. It possesses core advantages of being environmentally friendly, energy-efficient, and stable and reliable, making it suitable for the sustainable management of various eutrophic water bodies. All other unmentioned parts are existing technologies.
