Description

Technical Field

[0001] This application relates to the field of deep-water lake reoxygenation technology, specifically to an outlet water system for bottom reoxygenation in deep-water lakes and reservoirs. Background Technology

[0002] Large and medium-sized lakes and reservoirs have thick bottom sediments with a large amount of organic matter deposited at the bottom. The decomposition of this organic matter requires a large amount of oxygen, but due to the depth of the water and the stratification of water temperature, the abundant dissolved oxygen in the upper layer cannot be transported to the lower layer in time, thus causing the problem of oxygen deficiency at the bottom of the lake or reservoir.

[0003] Oxygen deficiency at the bottom of deep lakes and reservoirs has several negative consequences. First, it impacts the survival and reproduction of aquatic life, leading to mass mortality of fish, plankton, and other organisms, severely affecting the sustainable development of fisheries resources. Second, it disrupts the balance of the aquatic ecosystem, exacerbating eutrophication. Third, it affects water quality, causing deterioration and negatively impacting drinking water safety in surrounding areas. Without timely water environment remediation, the continuous decomposition of organic matter in the bottom sediment will further deplete dissolved oxygen, eventually leading to the depletion of dissolved oxygen at the bottom of rivers, lakes, and reservoirs, resulting in a putrid odor.

[0004] Traditional reoxygenation technologies, such as mechanical aeration and chemical dosing, can alleviate hypoxia to some extent, but their effects are minimal or only exist at the water surface, failing to address the anaerobic conditions in deep-water rivers, lakes, and reservoirs. Furthermore, existing deep-water reoxygenation systems generally suffer from limitations such as low reoxygenation efficiency, high construction difficulty, and high maintenance costs. Therefore, developing a highly efficient, economical, and easy-to-maintain bottom-layer reoxygenation system for deep-water lakes and reservoirs has become a key research focus. Summary of the Invention

[0005] In view of the technical problems existing in the background art, this application provides an effluent system for bottom reoxygenation of deep-water lakes and reservoirs. The construction and maintenance of this system are relatively simple, and it can achieve precise reoxygenation to improve reoxygenation efficiency.

[0006] This application provides a water outlet system for reoxygenation of the bottom layer of a deep-water lake reservoir, including a reoxygenation device, at least one outlet main pipe connected to the oxygen-enriched water outlet of the reoxygenation device, a plurality of water distribution devices installed on the outlet main pipe, and vertical branch pipes installed vertically in the water body; the outlet main pipe is connected to a plurality of main pipe floats to make the outlet main pipe float on the water surface; the water distribution device includes a water distribution pipe connecting the outlet main pipe and the vertical branch pipe.

[0007] In the technical solution of this application embodiment, by setting a main pipe float, the outlet main pipe can float on the water surface, avoiding the complexity and high cost of traditional underwater construction. This design not only reduces the construction difficulty, but also allows the outlet main pipe to be moved at any time as needed, significantly improving the system's flexibility and applicability. On this basis, by setting a water distribution device and vertical branch pipes, this application can use the water distribution device to connect the outlet main pipe floating on the water surface with the vertical branch pipes set vertically in the water body. This ensures that the main pipe floats on the water surface while allowing part of the pipe to be vertically lowered to the bottom of the lake or reservoir for deep reoxygenation, thereby significantly increasing the dissolved oxygen concentration of the bottom water. Moreover, the position and length of the vertical branch pipes can be set according to actual needs, so as to accurately set the position and depth of the reoxygenation point according to the needs of different water bodies, further improving the flexibility and adaptability of the outlet system, and providing an efficient and sustainable solution for the ecological management of deep-water lakes and reservoirs.

[0008] In some embodiments, the water distribution device further includes a top float disposed at the top of the water distribution pipe and a bottom float disposed at the bottom of the water distribution pipe; the top float and the bottom float are connected by bolts.

[0009] In this embodiment, by setting up top and bottom floats, the water distribution device can be prevented from sinking.

[0010] In some embodiments, a safety ring is provided on the outer side of the bottom float.

[0011] In this embodiment, a safety ring is provided for a steel wire rope to pass through, which can be used to connect the vertical branch pipe and the bottom float, thereby preventing the vertical branch pipe from sinking to the bottom of the lake during maintenance and installation, making the construction and maintenance process more convenient.

[0012] In some embodiments, the water outlet system further includes a release device communicating with the bottom outlet of the vertical branch pipe; the release device is vertically arranged, and a plurality of water outlet holes are uniformly arranged circumferentially on the bottom sidewall of the release device.

[0013] In this embodiment, by uniformly arranging water outlet holes along the circumference of the bottom sidewall of the vertically arranged release device, the oxygen-enriched water entering the release device can be uniformly sprayed out through each water outlet, so that the water outflow reaction force of each water outlet can cancel each other out, thereby ensuring that the pipeline is stable and does not shake; and the water outflow direction of each water outlet is horizontal, which can avoid disturbing the sediment at the bottom of the lake.

[0014] In some embodiments, the distance between the water outlet and the bottom sediment of the lake is 1 to 1.5 m.

[0015] In this embodiment, by controlling the distance between the water outlet and the bottom sediment, it is possible to avoid disturbing the bottom sediment and to fully deliver oxygen-rich water to the oxygen-deficient lake bottom, thereby significantly increasing the dissolved oxygen concentration of the bottom water, accelerating the degradation of organic pollutants in the water, effectively restoring the ecosystem, and significantly improving water quality.

[0016] In some embodiments, the water outlet main includes a plurality of sequentially connected water outlet pipes.

[0017] In this embodiment, by connecting multiple water outlet pipes to form a main water outlet pipe, it is not only convenient to connect the main water outlet pipe to the water distribution device, but also convenient to adjust the overall length and arrangement of the main water outlet pipe, which helps to improve the flexibility and adaptability of the system.

[0018] In some embodiments, the water distribution pipe is disposed between two adjacent water outlet pipes; the water distribution pipe includes a first pipe connecting the water outlet pipes on both sides and a second pipe vertically disposed at the bottom of the first pipe; the outlet end of the second pipe is connected to the vertical branch pipe.

[0019] In this embodiment, by setting up a branch pipe between adjacent outlet pipes in the main outlet pipe, the oxygen-enriched water in the outlet pipe can be diverted, with one part being output to the vertical branch pipe for deep reoxygenation, and the other part being further transported to the location of the next vertical branch pipe through the outlet pipe. Furthermore, the location of the branch pipe can be freely set as needed, the overall structure is relatively simple, and the construction process is convenient.

[0020] In some embodiments, the vertical branch pipe includes a plurality of sequentially connected vertical pipes.

[0021] In this embodiment, by connecting multiple vertical pipes to form a vertical branch pipe, the length of the vertical branch pipe can be adjusted according to the different depths of the deep lake and the reoxygenation requirements, which helps to improve the flexibility and adaptability of the system.

[0022] In some embodiments, the main pipe floats are spaced apart on the outer wall of the outlet main pipe along the water flow direction.

[0023] In this embodiment, by setting several main pipe floats at intervals on the outer wall of the main water outlet pipe, not only is operation convenient, but the main water outlet pipe can also be kept floating on the water surface, thereby avoiding the sinking of the pipe, reducing the resistance of pipe dragging, and effectively improving the convenience of construction.

[0024] In some embodiments, the reoxygenation device is an ultra-nano aerosol reoxygenation device.

[0025] In this embodiment, by setting up an ultra-nano dissolved oxygenation device, supersaturated oxygen can be dissolved in water in the form of ultra-nano bubbles, thereby forming oxygen-enriched water, which can effectively increase the dissolved oxygen content in the water.

[0040] To address the common problems of low reoxygenation efficiency, high construction difficulty, and high maintenance costs in existing deep-water lake reoxygenation systems, this application provides an outlet water system for bottom reoxygenation in deep-water lakes and reservoirs. By laying the main pipeline (i.e., outlet main pipe 2) on the lake surface, the construction difficulty is effectively reduced compared to traditional underwater construction, and the subsequent maintenance cost is also lower. On this basis, a portion of the pipeline (i.e., vertical branch pipe 5) is vertically lowered to the bottom of the lake and reservoir through a water distribution device 4 for deep and precise reoxygenation, which effectively improves the reoxygenation efficiency and can significantly increase the dissolved oxygen concentration of the bottom water.

[0041] Specifically, please refer to the following: Figure 1-2 The water outlet system for reoxygenation of the bottom layer of a deep-water lake provided in this application embodiment includes a reoxygenation device 1, at least one outlet main pipe 2 connected to the oxygen-enriched water outlet of the reoxygenation device 1, a plurality of water distribution devices 4 installed on the outlet main pipe 2, and vertical branch pipes 5 vertically installed in the water body. The outlet main pipe 2 is connected to a plurality of main pipe floats 3 to make the outlet main pipe 2 float on the water surface; the water distribution device 4 includes a water distribution pipe 41 connecting the outlet main pipe 2 and the vertical branch pipe 5, for diverting the oxygen-enriched water in the outlet main pipe 2 to the vertical branch pipe 5.

[0042] In the technical solution of this application embodiment, the main outlet pipe 2 is laid on the lake surface using the main pipe float 3, and the oxygen-enriched water in the main outlet pipe 2 is transported to the vertical branch pipe 5 inside the water body using the water distribution device 4. This ensures that most of the pipes float on the water surface while some pipes are vertically lowered to the bottom of the lake. This reduces construction difficulty and maintenance costs, and allows for precise reoxygenation of the areas that need reoxygenation. Furthermore, the position and length of the vertical branch pipe 5 are adjustable, enabling the transport of oxygen-enriched water to the anoxic area above the bottom sediment of the deep lake, achieving deep reoxygenation. This significantly increases the dissolved oxygen concentration of the bottom water, accelerates the degradation of organic pollutants in the water, effectively restores the ecosystem, and significantly improves water quality, providing an efficient and sustainable solution for the ecological management of deep lakes and reservoirs.

[0043] Specifically, in this embodiment, the function of the reoxygenation device 1 is to extract water from the water body and dissolve oxygen in the water to increase the dissolved oxygen content in the water body, thereby obtaining oxygen-enriched water. The reoxygenation device 1 in this embodiment can be any existing reoxygenation device 1, as long as it can increase the dissolved oxygen content in the water. More preferably, the reoxygenation device 1 can be an ultra-nano dissolved oxygenation device 1 to form supersaturated nanobubble oxygen-enriched water, which can improve the reoxygenation efficiency and the dissolved oxygen content in the water body compared to other types of reoxygenation devices 1.

[0044] Furthermore, in the embodiments of this application, the outlet main pipe 2 can be a single pipe or multiple pipes, depending on actual needs, and this application is not limited thereto. More specifically, in some embodiments of this application, the outlet main pipe 2 is composed of several outlet pipes connected sequentially. This arrangement facilitates the addition of a water distribution device 4 between two adjacent outlet pipes and allows for adjustments to the length and arrangement of the outlet main pipe 2, enabling large-arc bends in the outlet main pipe 2, which improves the flexibility and adaptability of the system. The material of the outlet pipes can be selected according to actual needs, with PE pipes being more preferred.

[0045] Furthermore, in this embodiment, the main pipe floats 3 are spaced apart on the outer wall of the outlet main pipe 2 along the water flow direction. Figure 1-2 The smaller squares outside the outlet main pipe 2 represent the main pipe floats 3. The number and spacing of these floats 3 can be adjusted according to actual needs, ensuring that the outlet main pipe 2 can float on the water surface.

[0046] Furthermore, please refer to the following: Figure 3 In this embodiment, the water distribution device 4 further includes a top float 42 disposed at the top of the water distribution pipe 41 and a bottom float 43 disposed at the bottom of the water distribution pipe 41. The sidewalls of the top float 42 and the bottom float 43 at opposite positions are provided with float bolt holes 44. By passing bolts through the float bolt holes 44 in the top float 42 and the bottom float 43, the top float 42 and the bottom float 43 can be stably connected. This arrangement effectively prevents the water distribution device 4 from sinking. More preferably, a safety ring 45 is also provided on the outside of the bottom float 43; this safety ring 45 is used for a steel wire rope to pass through, allowing the steel wire rope to connect the vertical branch pipe 5 and the bottom float 43, thereby preventing the vertical branch pipe 5 from sinking to the bottom of the lake during maintenance and installation, making the construction and maintenance process more convenient.

[0047] More specifically, in this embodiment, the water distribution device 4 has a water distribution pipe 41 positioned between two adjacent outlet pipes. The water distribution pipe 41 includes a first pipe 411 connecting the two outlet pipes and a second pipe 412 vertically positioned at the bottom of the first pipe 411. The first pipe 411 and the second pipe 412 are connected, with the outlet end of the second pipe 412 connected to the inlet end of the vertical branch pipe 5. Furthermore, a top float 42 and a bottom float 43 are respectively positioned at the top and bottom of the first pipe 411, with the bottom float 43 having a hole for the second pipe 412 to extend from. This configuration allows for the diversion of oxygen-enriched water in the outlet pipes, enabling the oxygen-enriched water in the outlet pipes on the inlet side to enter the first pipe 411. A portion of this oxygen-enriched water is then output through the second pipe 412 to the vertical branch pipe 5 for deep reoxygenation, while the remaining portion is transported through the first pipe 411 to the outlet pipe on the outlet side, and then further transported to the location of the next vertical branch pipe 5. Furthermore, the positions of the 41 water distribution pipes can be freely set as needed, the overall structure is relatively simple, and the construction process is also relatively convenient.

[0048] Furthermore, please refer to the following: Figure 4 In some embodiments, the top inlet of the vertical branch pipe 5 is connected to the outlet of the second pipe 412, and the bottom outlet of the vertical branch pipe 5 is connected to the release device 6. The release device 6 is used to evenly spray the oxygen-enriched water input from the vertical branch pipe 5 into the water body, thereby delivering oxygen-enriched water to the oxygen-enriched point at a specified depth to solve the problem of oxygen deficiency at the bottom of the lake.

[0049] Furthermore, in some embodiments, the vertical branch pipe 5 is formed by sequentially connecting several vertical pipes, so that the length of the vertical branch pipe 5 can be adjusted to adapt to deep-water lakes and reservoirs of different depths. Each vertical pipe is preferably a rubber hose, and the total length of the vertical branch pipe 5 is preferably 10–100 m.

[0050] Furthermore, please refer to the following: Figure 4 In some embodiments, the release device 6 is vertically arranged and cylindrical, with a plurality of water outlet holes 61 evenly arranged circumferentially on the bottom sidewall of the release device 6. This arrangement ensures that the water outlets all flow horizontally, avoiding disturbance of the lakebed sediment and effectively preventing water quality degradation and blockage of the water outlet holes 61 caused by sediment agitation. Furthermore, because the water outlet holes 61 are evenly arranged and the circumferential angles between adjacent water outlet holes 61 are consistent, the reaction forces of the water outlet holes 61 can cancel each other out during spraying, thus ensuring the stability of the pipeline without shaking. More specifically, to effectively address the problem of oxygen deficiency at the lakebed, the distance between the water outlet holes 61 and the bottom sediment is preferably 1–1.5 m.

[0051] Furthermore, in some embodiments, the connection methods between the reoxygenation device 1, the outlet main pipe 2, the water distribution device 4, the vertical branch pipe 5 and the release device 6, as well as the connection methods between each outlet pipe and between each vertical pipe, are preferably detachable connections, so as to be adjusted according to actual needs and improve the flexibility and adaptability of the system.

[0052] The working process of the effluent system for bottom reoxygenation in deep-water lakes provided in the embodiments of this application is described below:

[0053] When installing the water outlet system for bottom reoxygenation in deep-water reservoirs as described in this application, firstly, based on the actual shape and depth of the target deep-water reservoir, design the reoxygenation points on the lake bottom that require reoxygenation. Then, determine the position and length of the corresponding outlet main pipe 2 at the location of the reoxygenation point on the lake surface, and assemble the outlet pipes into outlet main pipe 2. Install a main pipe float 3 on the outside of the outlet pipe to ensure that the outlet pipe floats on the water surface. Next, install the water distribution device 4 at the location corresponding to the reoxygenation point. During installation, the vertical branch pipe 5 can be hung on the safety port of the water distribution device 4 with a steel wire rope. After the water distribution device 4 is installed, connect the vertical branch pipe 5 to the bottom of the second pipe 412, and then connect the release device 6 to the bottom of the vertical branch pipe 5. The length of the vertical branch pipe 5 can be adjusted by adjusting the number of vertical pipes so that the outlet hole 61 of the release device 6 is located at a distance of 1 to 1.5 m from the bottom sediment. The ultra-nano dissolved oxygenation device 1 can be set up on the shore. Water from the lake is pumped into the oxygenation device 1 through a corresponding pumping mechanism for oxygenation. The outlet of the oxygen-rich water is connected to the outlet main pipe 2.

[0054] After the installation of the water outlet system is completed, the ultra-nano dissolved oxygenation device 1 is turned on, and the oxygen-enriched water generated is transported to the location of each water distribution device 4 through the water outlet main pipe 2 floating on the lake surface. The oxygen-enriched water is then transported to the vertical branch pipe 5 through the water distribution device 4, and then released through the water outlet 61 of the release device 6. This achieves deep and precise oxygenation, effectively improves the oxygenation efficiency, solves the problem of oxygen deficiency at the bottom of the lake, and the overall installation process and subsequent maintenance process are relatively convenient and low in cost.

[0055] In summary, this application provides a water outlet system for reoxygenation of the bottom layer of deep-water lakes and reservoirs, belonging to the field of deep-water lake and reservoir reoxygenation technology. The water outlet system includes a reoxygenation device 1, at least one outlet main pipe 2 connected to the oxygen-enriched water outlet of the reoxygenation device 1, several water distribution devices 4 installed on the outlet main pipe 2, and vertical branch pipes 5 vertically installed in the water body; wherein, the outlet main pipe 2 is connected to several main pipe floats 3 to make the outlet main pipe 2 float on the water surface; the water distribution device 4 includes a water distribution pipe 41 connecting the outlet main pipe 2 and the vertical branch pipe 5, for diverting the oxygen-enriched water in the outlet main pipe 2 to the vertical branch pipe 5. Through the above methods, this application enables the main pipe float 3 to float on the water surface, reducing construction difficulty and cost, and improving the system's flexibility and applicability. At the same time, this application uses the water distribution device 4 and vertical branch pipe 5 to directly transport oxygen-rich water to the oxygen-deficient area above the bottom sediment of deep lakes and reservoirs, achieving deep reoxygenation and precise reoxygenation, which can effectively increase the dissolved oxygen concentration of the bottom water.

[0056] It should be noted that this application is not limited to the above-described embodiments. The above embodiments are merely examples, and any embodiments with the same structure and effect as the technical concept within the scope of this application are included in the technical scope of this application. Furthermore, various modifications that can be conceived by those skilled in the art to the embodiments, and other ways of constructing by combining some of the constituent elements of the embodiments, without departing from the spirit of this application, are also included in the scope of this application.
