Description

Technical Field

[0001] This utility model relates to the field of water purification technology for enclosed landscape water bodies, specifically, to a water purification system for enclosed landscape water bodies in urban parks. Background Technology

[0002] Urban parks are an important part of the urban ecosystem and landscape, providing urban residents with places to rest, stroll, exercise, socialize, and hold various collective cultural activities. Landscape lakes play a vital role in urban parks; they are not only the center of the landscape environment but also maintainers of ecological balance. The waterfront platforms, walking paths, and other facilities surrounding landscape lakes offer visitors diverse recreational activities such as getting close to nature, swimming, and playing in the water.

[0003] Most urban park landscape lakes are closed, stagnant bodies of water. These lakes are located in low-lying areas where rainwater collects. They are characterized by small capacity, shallow depth, stagnant water, and poor flow. These lakes mainly rely on natural rainfall as their water source, supplemented with tap water during the dry season to maintain a minimum water depth. Because there is no submerged vegetation on the lakebed, the water's self-purification capacity is very weak. Coupled with the influence of surface pollution, these landscape lakes are turbid, eutrophic, and algae-rich water year-round. The water is green or brown, with a transparency of less than 0.5 meters, and emits a fishy odor, failing to achieve the desired landscape effect.

[0004] In order to solve the above-mentioned technical problems, in recent years many parks have begun to introduce aquatic plants to purify water quality in their landscape lakes. However, due to the lack of comprehensive control over factors such as water sources and aquatic ecosystems, they often only focus on the aquatic plants themselves. The resulting aquatic vegetation is often short-lived and quickly degrades, resulting in poor effects.

[0005] The above-mentioned defects urgently need to be addressed. Utility Model Content

[0006] To address the problem that the existing methods of introducing aquatic plants to purify water in park landscape lakes have not been very effective, this invention provides a water purification system for enclosed landscape water bodies in urban parks.

[0007] The technical solution of this utility model is as follows:

[0008] A water purification system for enclosed landscape water bodies in urban parks includes multiple water intakes and multiple water inlets. The multiple water intakes are spaced apart in the middle area of ​​the bottom surface of the enclosed landscape water body, and the multiple water inlets are spaced apart on the shoreline of the enclosed landscape water body. The water intakes are connected to the corresponding inlets of the water purification components through a first pump set, and the outlets of the water purification components are connected to the corresponding water inlets through a second pump set, so as to achieve water purification of the enclosed landscape water body.

[0009] According to the present invention based on the above scheme, the water purification component includes an MBBR biological treatment unit, a flocculation unit, and a physical filtration unit. The inlet of the MBBR biological treatment unit is connected to the corresponding water intake through the first pump group. The outlet of the MBBR biological treatment unit is connected to the inlet of the flocculation unit. The outlet of the flocculation unit is connected to the inlet of the physical filtration unit. The outlet of the physical filtration unit is connected to the corresponding water supply through the second pump group.

[0010] According to the above-described scheme of this utility model, the physical filtration unit is a fiber filtration unit.

[0011] According to the above-described scheme of this utility model, the MBBR biological treatment unit and the flocculation unit are both located underground, while the fiber filtration unit is located on the ground.

[0012] According to the above-described scheme of this utility model, the physical filtration unit is an activated sand filter unit.

[0013] According to the above-described scheme of this utility model, the MBBR biological treatment unit, the flocculation unit, and the activated sand filter unit are all located underground.

[0014] According to the above-described scheme, this utility model also includes a water intake well, the inlet of which is connected to the corresponding water intake via the first pump unit, and the outlet of which is connected to the inlet of the MBBR biological treatment unit.

[0015] According to the above-described scheme, this utility model also includes a water replenishment well, the inlet of which is connected to the outlet of the physical filtration unit, and the outlet of which is connected to the corresponding water replenishment outlet through the second pump assembly.

[0016] According to the above-described scheme, this utility model also includes a blower unit, which is connected to the MBBR biological treatment unit, the physical filtration unit, and the water replenishment well.

[0017] The advantages of this utility model based on the above solution are as follows:

[0018] In the aforementioned water purification system for enclosed landscape water bodies in urban parks, the water intake is connected to the corresponding inlet of the water purification component via the first pump set, and the outlet of the water purification component is connected to the corresponding water replenishment outlet via the second pump set. This allows water from the enclosed landscape water body to be taken to the water purification component for purification and then replenished back into the enclosed landscape water body, achieving a "one in, one out" water circulation mode. This not only effectively purifies the enclosed landscape water body but also improves the clarity and transparency of the water, thereby achieving an ideal landscape effect.

[0019] In addition, multiple water intakes are spaced out in the middle of the bottom of the enclosed landscape water body, and multiple water replenishment points are spaced out on the shoreline of the enclosed landscape water body. This allows the water in the enclosed landscape water body to flow between the water replenishment points and the water intake points, thereby enhancing water flow and material exchange and inhibiting algae growth.

Detailed Implementation

[0024] To make the technical problem to be solved, the technical solution, and the beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0025] Example 1

[0026] like Figure 1 , Figure 2 As shown, this utility model provides a water purification system for enclosed landscape water bodies in urban parks, including multiple water intakes 2 and multiple water inlets 3. The multiple water intakes 2 are spaced apart in the middle area of ​​the bottom surface of the enclosed landscape water body 1, and the multiple water inlets 3 are spaced apart on the shoreline of the enclosed landscape water body 1, thus forming a water circulation path from the bottom of the water body to the shoreline. In addition, the multiple water inlets 3 spaced apart on the shoreline of the enclosed landscape water body 1 allows the water in the enclosed landscape water body 1 to form convection between the water inlets 3 and the water intakes 2, enhancing water flow and material exchange, reducing the formation of stagnant areas, and inhibiting algae growth.

[0027] like Figure 1 , Figure 2As shown, in this embodiment, the water intake 2 is connected to the inlet of the water purification component 5 through the first pump water group 4, and the outlet of the water purification component 5 is connected to the corresponding water replenishment 3 through the second pump water group 6. Thus, the water of the closed landscape water body 1 is taken to the water purification component 5 for purification and then replenished back into the closed landscape water body 1, realizing a "one in, one out" water circulation mode. This not only effectively purifies the closed landscape water body 1, but also improves the clarity and transparency of the water, thereby achieving an ideal landscape effect.

[0028] like Figure 1 As shown, in this embodiment, the water purification component 5 includes an MBBR biological treatment unit 51, a flocculation unit 52, and a physical filtration unit 53. The inlet of the MBBR biological treatment unit 51 is connected to the corresponding water intake 2 via a first pump assembly 4. The first pump assembly 4 pumps water from the enclosed landscape water body 1 into the MBBR biological treatment unit 51. The MBBR biological treatment unit 51 utilizes microorganisms for nitrification or denitrification reactions, which can significantly remove ammonia nitrogen, total nitrogen, and total phosphorus from the water, exhibiting excellent nitrogen and phosphorus removal effects. Furthermore, the outlet of the MBBR biological treatment unit 51 is connected to the inlet of the flocculation unit 52 via a first pipe, thereby transporting the water treated by the MBBR biological treatment unit 51 to the flocculation unit 52. The flocculation unit 52 uses flocculants (such as PAM or PAC) to destabilize colloids, thereby removing suspended solids and some recalcitrant organic matter from the water, further purifying the water treated by the MBBR biological treatment unit 51 and ensuring that the effluent water quality meets higher standards. In addition, the outlet of the flocculation unit 52 is connected to the inlet of the physical filtration unit 53 through a second pipe, thereby transporting the water treated by the flocculation unit 52 to the physical filtration unit 53. The physical filtration unit 53 effectively removes microplastics, flocs formed by the flocculation unit 52, and other suspended particles from the water, improving the water clarity. At the same time, the outlet of the physical filtration unit 53 is connected to the corresponding water supply port 3 through the second pump water group 6, thereby transporting the purified water back into the enclosed landscape water body 1, realizing water circulation purification, reducing the concentration of nutrients such as nitrogen and phosphorus in the enclosed landscape water body 1, and removing algae and microorganisms in the water, thus improving the water clarity.

[0029] It should be noted that the MBBR biological treatment unit 51 uses microorganisms to carry out nitrification or denitrification reactions, the flocculation unit 52 uses flocculants to destabilize and precipitate colloids, and the physical filtration unit 53 removes microplastics and other suspended particles from the water. These are all existing technologies, and this utility model is also an improvement on these parts. Therefore, its principles and processes will not be described in detail.

[0030] In this embodiment, the physical filtration unit 53 is a fiber filtration unit. The fiber filtration unit uses fiber material as the filter medium. The fiber material is short fiber with a length of 1cm to 2cm. It can more effectively capture and retain small particles in the water. Compared with traditional sand filtration or activated carbon filtration, the fiber filtration unit shows higher efficiency and precision in removing these small pollutants, thereby further improving the quality of the effluent.

[0031] like Figure 1 As shown, in this embodiment, both the MBBR biological treatment unit 51 and the flocculation unit 52 are located underground, which effectively reduces the occupation of ground space. This not only protects the natural landscape and green vegetation but also avoids the impact of the treatment facilities on the overall aesthetics of the park. Furthermore, underground facilities generally blend better into the surrounding environment, reducing visual and auditory disturbances and enhancing the visitor experience. In addition, the MBBR biological treatment unit 51 and the flocculation unit 52 may generate some noise and odor during operation. Placing them underground utilizes the natural barriers of the soil and surface to effectively isolate these adverse factors, reducing interference with the surrounding environment and visitors. Moreover, the fiber filtration unit is located above ground, allowing for more intuitive and convenient monitoring and management, facilitating daily inspections, maintenance, and cleaning, and enabling the timely detection and handling of any potential problems. Secondly, the above-ground location of the fiber filtration unit also allows for better cleaning of its internal fiber materials, helping to maintain the cleanliness of the equipment and extend its service life.

[0032] like Figure 1 As shown, in this embodiment, the flocculation unit 52 includes a purification tank 521 and a dosing assembly 522. The dosing assembly 522 is connected to the purification tank 521. The inlet of the purification tank 521 is connected to the outlet of the MBBR biological treatment unit 51, and the outlet of the purification tank 521 is connected to the inlet of the physical filtration unit 53. The purification tank 521 is located underground, while the dosing assembly 522 is located above ground, facilitating the addition of reagents to the purification tank 521 to purify the water. The reagents required for water purification enter the purification tank 521 through the dosing assembly 522, stirring the purification tank 521 and destabilizing dissolved pollutants (such as phosphorus), small particulate colloidal substances, algal cells, etc., in the water, forming large flocs. These large flocs are removed by filtration in subsequent units.

[0033] like Figure 1As shown, in this embodiment, a water intake well 7 is provided between the MBBR biological treatment unit 51 and the enclosed landscape water body 1. The inlet of the water intake well 7 is connected to the corresponding water intake 2 through a first pump group 4. The first pump group 4 draws water from the enclosed landscape water body 1 into the water intake well 7, and the outlet of the water intake well 7 is connected to the inlet of the MBBR biological treatment unit 51 through a third pump group. The third pump group draws water from the water intake well 7 into the MBBR biological treatment unit 51. The water intake well 7 can temporarily store the water drawn from the enclosed landscape water body 1, which helps to balance the water flow in the system. Especially when the treatment demand fluctuates, it can ensure that the MBBR biological treatment unit 51 receives and treats the water at a stable water flow rate, avoiding the impact of unstable water flow on the treatment effect.

[0034] like Figure 1 As shown, in this embodiment, a water replenishment well 8 is provided after the physical filtration unit 53. The inlet of the water replenishment well 8 is connected to the outlet of the physical filtration unit 53 through a third pipe, and the outlet of the water replenishment well 8 is connected to the corresponding water replenishment port 3 through a second pump assembly 6. The water replenishment well 8 can temporarily store the water treated by the physical filtration unit 53, and the water replenishment well 8 can be transported to the enclosed landscape water body 1 through the second pump assembly 6, which helps to realize the recycling of water resources. In addition, when the treatment efficiency of the physical filtration unit 53 decreases or maintenance is required, the water replenishment well 8 can temporarily store the treated water to ensure that the enclosed landscape water body 1 is not affected.

[0035] like Figure 1 As shown, in this embodiment, the water purification system of this utility model also includes an aeration unit 9, which is connected to the MBBR biological treatment unit 51, the fiber filtration unit, and the water replenishment well 8. The aeration unit 9 aerates the MBBR biological treatment unit 51, increasing the dissolved oxygen content in the water, promoting the growth and activity of microorganisms, thereby improving the efficiency of biological treatment processes such as organic matter degradation and nitrification, and helping to improve the overall water purification effect. In addition, the aeration unit 9 aerates the fiber filtration unit, facilitating the cleaning of the fiber material inside the fiber filtration unit. Furthermore, the aeration unit 9 aerates the water replenishment well 8, increasing the dissolved oxygen content in the water in the well 8. Sufficient dissolved oxygen is beneficial to the survival and reproduction of aquatic organisms, and also helps maintain the freshness and cleanliness of the water. When this purified water is used to replenish the enclosed landscape water body 1, it can reduce the risk of eutrophication and provide a better living environment for aquatic plants and animals.

[0036] Example 2

[0037] like Figure 3As shown, unlike Embodiment 1, the physical filtration unit 53 in this embodiment is an activated sand filter unit. The tiny pores formed between the activated sand particles can trap suspended solids, colloids, organic matter, and other impurities in the water, effectively removing physical pollutants. Furthermore, during operation, the activated sand filter unit achieves self-cleaning through the combined action of water flow and air blown out by the blower unit 9. The mutual friction and scouring between the sand particles help remove impurities adhering to the surface of the sand particles, preventing clogging, extending the service life of the filter unit, and reducing maintenance frequency and costs.

[0038] like Figure 3 As shown, in this embodiment, the MBBR biological treatment unit 51, the flocculation unit 52, and the activated sand filter unit are all located underground, which can make full use of underground space, reduce the occupation of ground land, reduce the impact on the surrounding environment and residents' lives, improve the concealment and safety of the facilities, and at the same time reduce the impact of noise and odor on the surrounding environment, thereby improving the quality of life of the surrounding residents.

[0039] It should be understood that those skilled in the art can make improvements or modifications based on the above description, and all such improvements and modifications should fall within the protection scope of the appended claims.

[0040] The present utility model patent has been described above with reference to the accompanying drawings.

Any improvements made by adopting the inventive concept and technical solution of the present utility model patent, or the direct application of the inventive concept and technical solution of the present utility model patent to other occasions without modification, are all within the protection scope of the present utility model.
