[0002] Landscape ponds are artificially constructed or renovated water facilities whose core functions are landscape appreciation, environmental beautification, and ecological regulation. The most common core pollutants in landscape ponds are organic pollutants derived from biological metabolism (decaying aquatic plants and excrement from aquatic animals) and external inputs (nutrient residues). Long-term deposition of organic pollutants in landscape ponds can lead to eutrophication, impairing the landscape effect and potentially causing chain reactions such as water quality deterioration and ecological imbalance. Therefore, preventing the deposition of organic pollutants in the ponds is a primary measure for maintaining a stable landscape pond environment.

DETAILED DESCRIPTION

[0029] The specific embodiments of the present invention are described below with reference to the accompanying drawings. In order to fully understand the present invention, many details are described below, but for those skilled in the art, the present invention can be implemented without these details.

[0030] Example 1: Reference Figure 1 and Figure 2 A landscape pool sewage collection system includes a landscape pool 1, a flow disturbance device 2, and a pumping device 3. The bottom of the landscape pool 1 is provided with a high area and a low area with a height difference. The flow disturbance device 2 and the pumping device 3 are both located in the low area. The focus of the present invention is the design concept of "pool bottom height difference + flow disturbance + pumping". The specific design reasons for this design concept are as follows: (1) Pool bottom height difference: Due to the height difference at the bottom of the landscape pool, water in the high area will naturally fall to the low area under the action of gravity, thus forming a water flow trend from the high area to the low area, and thus causing pollutants in the water to be suspended or flowing; (2) Flow disturbance: The flow disturbance device 2 can promote the formation of regular and stable water flow disturbance in the low area, thereby strengthening the water flow trend from the high area to the low area, and further pushing the water carrying pollutants to the pumping device 3; (3) Pumping: The pumping device 3 is set in front of the water flow direction. Its functions include the following two points: on the one hand, the pumping device 3 can enhance the degree of water flow disturbance in the low area to ensure a more stable water flow trend at the bottom of the landscape pool; on the other hand, the pumping device 3 can simultaneously pump water and pollutants out of the landscape pool 1 to facilitate subsequent purification treatment.

[0031] It can be seen that by setting up a high area and a low area with a height difference in the landscape pool 1, and by the cooperation between the flow disturbance device 2 and the pumping device 3 in the low area, the landscape pool 1 can be automatically cleaned and pollutant collected, thereby avoiding the problem of pollutant deposition, eliminating the tedious process of draining water and salvaging aquatic organisms in advance, and the operation is simple and convenient, with high feasibility, effectively overcoming the defects of the existing technology.

[0032] Reference Figure 1 and Figure 2 In this embodiment, the lower area includes several ditches 11 arranged at the bottom of the landscape pool 1, and the upper area includes several platforms 12 arranged outside the ditches 11. The flow disturbance device 2 and the pumping device 3 are arranged sequentially in the direction of water flow within the ditches 11, thereby forming a regular water flow disturbance within the ditches 11 and simultaneously pumping the water and pollutants out of the landscape pool 1. The use of ditches 11 to set up the lower area can easily create a height difference at the bottom of the landscape pool 1, and facilitate the subsequent shielding and decoration of the ditches 11, thereby achieving a hidden design of a hidden ditch. By arranging alternating ditches 11 and platforms 12, it is ensured that the treatment area of ​​the flow disturbance device 2 and the pumping device 3 can effectively cover the entire landscape pool 1, preventing pollutants from settling in the corners of the pool bottom and causing pollution. The height difference between the ditches 11 and the platforms 12 is related to the specific specifications of the landscape pool 1 and the number, power, and other parameters of the flow disturbance device 2 and the pumping device 3. Therefore, it is not specifically limited in this embodiment. Those skilled in the art can conduct specific experiments and adjustments based on actual conditions.

[0033] Reference Figures 2 to 4Preferably, the ditch 11 has a narrowing shape that slopes from the wall toward the bottom. This reduces the cross-sectional area of ​​the water flow, thereby increasing the kinetic energy and impact force of the water flow. This allows the water flow to carry pollutants into the ditch 11 at a faster rate, further driving the flow of surrounding water, thereby enhancing the water flow disturbance effect and preventing pollutant deposition. The ditch 11 can be designed to have an arc-shaped structure, a V-shaped structure, or a trumpet-shaped structure. In this embodiment, a semicircular arc structure is designed.

[0034] Reference Figures 3 and 4 After testing, it was found that the design concept of "pool bottom height difference + disturbance + pumping" can effectively remove most of the pollutants deposited at the bottom of the landscape pool, but a very small amount of pollutants will still be deposited in the high area. In order to solve this problem, this embodiment provides a mushroom bed carrier for nitrifying bacteria to attach in the high area. The nitrifying bacteria living on the mushroom bed carrier can convert nitrogen-containing pollutants deposited in the high area into non-toxic nitrates through a "two-step synergistic reaction", thereby achieving a self-purification effect on the water body. It can be seen that the treatment method of timely sewage discharge and nitrifying bacteria decomposition can ensure that the pollutants in the landscape pool are effectively removed.

[0035] Reference Figures 2 to 4 In this embodiment, the bacterial bed carrier is preferably a floating filter material 13. Specifically, the floating filter material 13 can be selected from biochemical balls or suspended biochemical cotton. Since nitrifying bacteria are attached microorganisms and need to attach to the surface of the bacterial bed carrier to form a "biofilm", this embodiment provides a fixed grille 14 above the floating filter material 13. Specifically, the platform 12 is provided with a mounting groove 121, in which the floating filter material 13 is mounted, and a removable fixed grille 14 is installed at the notch of the mounting groove 121. The fixed grille 14 and the mounting groove 121 cooperate with each other to fix the floating filter material 13 and prevent the floating filter material 13 from being significantly displaced or disturbed by the water flow.

[0036] Reference Figure 2 Since the survival and metabolic activities of nitrifying bacteria are highly dependent on an oxygen-rich environment and a slightly disturbed water flow environment, this embodiment provides a diversion mechanism between the high area and the low area to transport the water flow in the low area to the bottom of the mushroom bed carrier, thereby forming a slight water flow disturbance trend at the bottom of the mushroom bed carrier, thereby providing good conditions for the growth of anaerobic bacteria. As a preferred embodiment, the diversion mechanism is a plurality of diversion channels 17 arranged between the ditch 11 and the platform 12. It should be noted that in order to provide nitrifying bacteria with an appropriate amount of oxygen, in actual applications, it is also necessary to set an aeration tray or a series oxygenation system in the high area. For example, the oxygenation system disclosed in the patent publication number CN206213026 can be used for specific implementation.

[0037] Reference Figures 3 and 4Each ditch 11 is topped with a decorative grille 15. The upper end surfaces of the decorative grille 15 and the fixed grille 14 are flush with each other and are covered with decorative materials 16. The decorative grille 15 serves two purposes: First, it isolates aquatic organisms from following the water flow into the ditch 11 and being extracted by the pumping device 3, thereby effectively protecting aquatic organisms; second, it provides a decorative effect, making the ditch 11 a hidden culvert. From the outside, there is no height difference at the bottom of the landscape pool 1, resulting in a more beautiful visual effect. The decorative grille 15 and the fixed grille 14 are coated with a TiO2 photocatalytic coating, which provides a self-cleaning function, thereby further improving the cleaning effect of the landscape pool sewage collection system.

[0038] Reference Figures 3 and 4 In order to further improve the aesthetics of the bottom of the landscape pool 1, decorations 16 are laid on the fixed grid 14 and the decorative grid 15. Preferably, the decorations 16 are pebbles.

[0039] Reference Figure 1 and Figure 3 To facilitate maintenance and inspection of the spoiler 2 and the pumping device 3, the decorative grille 15 is provided with inspection openings 151 at corresponding locations on the spoiler 2 and the pumping device 3, and is equipped with a removable inspection cover 152. The inner wall of the inspection opening 151 is provided with a circle of mounting bosses 153, and the bottom edge of the inspection cover 152 is provided with a step 154 ​​that matches the mounting bosses 153. This allows the inspection cover 152 to be smoothly embedded in the inspection opening 151, maintaining a flat and beautiful bottom of the landscape pond 1. The side wall of the inspection cover 152 is provided with an arc-shaped notch 155, which serves as a handle to facilitate the removal of the inspection cover 152 from the inspection opening 151.

[0040] Reference Figure 1 The flow-disturbing device 2 can be a conventional device capable of disturbing the water body, such as an aeration pump or a flow-propelling device, and the number of flow-disturbing devices 2 can be flexibly adjusted according to actual needs. In this embodiment, a plurality of flow-disturbing devices 2 are provided in each ditch 11, and the flow-disturbing device 2 is preferably a submersible flow-propelling aerator that has both aeration and flow-propelling functions.

[0041] Reference Figure 1, the pumping device 3 can be a conventional submersible pump in the prior art. In some embodiments, in order to simplify the production equipment, multiple submersible pumps can be set up, one of which is used for pumping water, and the other submersible pumps are installed in reverse, thereby replacing the flow disturbance device 2 to achieve the water flow disturbance function. If the area of ​​the landscape pool 1 is small and does not require a large-scale disturbance, the flow disturbance device 2 can be cancelled and a submersible pump can be directly used to achieve a small-scale disturbance and pumping function. If the area of ​​the landscape pool 1 is large, a wave-making submersible pump with a stronger flow disturbance function can also be used to cooperate with the flow disturbance device 2 to achieve auxiliary flow disturbance. The protection focus of this embodiment is the design concept of "pool bottom height difference + flow disturbance + pumping", and the pool bottom height difference design is the most core foundation. Therefore, based on the pool bottom height difference design scheme provided in this embodiment, in actual application, those skilled in the art can flexibly select suitable flow disturbance devices 2 and pumping devices 3 according to the specific environmental requirements of the landscape pool 1, thereby achieving effective conversion and efficient implementation.

[0042] Reference Figure 1 The pumping device 3 pumps the polluted pool water to the purification device outside the landscape pool 1 for purification treatment. The purified pool water is then transported back to the landscape pool 1 through the circulation pipeline, thereby achieving recycling. The main problem addressed by this embodiment is the sewage collection and treatment of the landscape pool 1, that is, how to efficiently collect the pollutants and discharge them outside the landscape pool 1. The purification process outside the landscape pool 1 is not the focus of this application, so its working principle and specific structure are not described in detail here. Those skilled in the art can use common purification devices such as centrifugal filters to achieve sewage purification.

[0043] Reference Figures 1 to 4 Verified by a third-party testing agency (CNAS certification), the landscape pond sewage collection system provided by this embodiment offers advantages over existing technologies, including high sediment removal rates, improved fish survival rates, low maintenance costs, and reduced energy consumption. The sediment removal rate is particularly significant. Specifically, according to 2022 statistics from the China Water Treatment Association, the sediment removal rate of existing landscape pond sewage treatment devices is less than 65%. However, based on the GB / T 31962-2015 test standard, the landscape pond sewage collection system provided by this embodiment achieves a sediment removal rate of 95.3% at the bottom of the landscape pond.

[0044] Example 2: Reference Figure 5 Different from the first embodiment, the guide mechanism in this embodiment is a guide groove 18 arranged between the ditch 11 and the platform 12. Compared with the embedded guide channel, the setting process of the guide groove 18 is simpler, which is conducive to reducing the configuration cost.

[0045] Example 3: Reference Figures 6 to 9Unlike the first embodiment, the lower area of ​​this embodiment comprises at least one pit 19 disposed at the bottom of the landscape pond 1, and the upper area is a platform 12 disposed outside the pit 19. Several flow disruptors 2 are arranged in a circular pattern at the mouth of the pit 19, and a pumping device 3 is disposed at the bottom of the pit 19. The circular arrangement of the flow disruptors 2 not only disturbs the water flow but also creates a centrifugal force within the pit 19, thereby guiding the water flow into a spiral downward motion. The centrifugal force and the direction of gravity form a combined downward oblique force, thereby achieving better water flow concentration and acceleration, thereby improving overall sewage collection performance.

[0046] Reference Figures 6 to 9 In order to avoid the formation of "air blockage" at the center of the pit mouth, the pit 19 is in a shape of a gradually shrinking mouth from the pit mouth to the pit bottom. The design principle is: the spiral water flow at the pit mouth has enough space in the upper thick pipe section to form a wall-adhering vortex and a central exhaust column. After the air is exhausted, when the water flows into the lower thin pipe section, the cross-sectional area is reduced and the flow rate naturally accelerates (Bernoulli principle). Therefore, the water flow assisted by centrifugal force can flow to the bottom of the pit more quickly, and thus be pumped away by the pumping device 3.

[0047] Reference Figures 6 to 9 As a preferred embodiment, this embodiment provides a conical concave pit 19 in the center of the landscape pond 1. Four flow disruptors 2 are located at the mouth of the concave pit 19. The flow disruptors 2 and pumping devices 3 are mounted within the concave pit 19 via mounting brackets. The mounting brackets can be flexibly selected and designed based on actual needs and are not limited here. In other embodiments, multiple concave pits 19 can be provided based on the area of ​​the landscape pond 1, and a common platform 12 can be provided outside the multiple concave pits 19 to ensure that the treatment area of ​​the flow disruptors 2 and pumping devices 3 effectively covers the entire landscape pond 1.

[0048] Reference Figures 1 to 9 This embodiment is suitable for larger landscape pools or those with circular or regular polygonal outlines, while Examples 1 and 2 are suitable for smaller landscape pools or those with strip-shaped outlines. As can be seen, based on the core concept of "pool bottom height difference + flow disturbance + water pumping", a variety of different implementation plans can be flexibly designed, making it widely applicable to fields such as garden landscaping and aquaculture.

[0049] The above is only a specific implementation of the present invention, but the design concept of the present invention is not limited to this. Any non-substantial changes to the present invention using this concept shall be deemed as an infringement of the protection scope of the present invention.
