Description

Technical Field

[0001] The present invention relates to the field of ecological governance, and particularly to a purification and restoration system for urban landscape water bodies. Background Art

[0002] With the acceleration of the urbanization process, the demand for water resources has increased, but pollution problems have led to a decline in water quality, affecting the effective supply of water resources. More than 30% of urban groundwater is polluted, and water pollution problems and environmental damage have become important obstacles to urban development.

[0003] Currently, the phytoremediation technology is to plant various aquatic plants on both sides of the river and in the water, which can improve water quality, promote the growth of aquatic organisms, and indirectly achieve the restoration of the river ecosystem. The phytoremediation technology can treat water bodies by absorbing pollutants through roots and absorbing carbon dioxide, air particles, etc. through photosynthesis.

[0004] The microbial remediation technology introduces or activates the natural microbial flora in the water body and uses its metabolic and degradation capabilities to convert pollutants (such as organic matter, ammonia nitrogen, phosphate, etc.) into harmless substances. The advantages include low energy consumption, no secondary pollution, and the ability to adapt to the dynamic changes of water quality.

[0005] Existing technologies utilize the synergistic effect of plant roots and microorganisms to remove pollutants (such as nitrogen, phosphorus, heavy metals);

[0006] Microbial agents (such as photosynthetic bacteria, nitrifying bacteria, etc.) may have a reduced activity due to sudden changes in water temperature, resulting in a decrease in the remediation efficiency. At the same time, plant growth is also restricted by light and temperature. For example, emergent plants are prone to death in low-temperature or highly polluted environments, leading to the interruption of remediation.

[0007] Secondly, in the phytoremediation technology, overly dense plant roots may block the floating island structure, causing the floating island to sink or the purification efficiency to decrease, and regular pruning is required, which is troublesome and inefficient.

[0008] Moreover, during the urban sewage treatment process, the water ecosystem is prone to blockage, affecting the sewage treatment effect. During long-term use, it is necessary to regularly replace the microbial sewage treatment device to ensure the sewage treatment effect. Summary of the Invention

[0009] An object of the present invention is to provide a purification and restoration system for urban landscape water bodies, which rotates the microbial carrier to different positions through a microbial unit to avoid blocking the microbial sewage treatment device and affecting the sewage treatment effect.

[0010] This object is achieved by the following technical solutions:

[0011] A purification and restoration system for urban landscape water bodies, comprising a number of microbial units. Each microbial unit includes a first adjusting rod and a second adjusting rod. A first gear and a second gear are respectively arranged at both ends of the first adjusting rod, and a third gear and a fourth gear are respectively arranged at both ends of the second adjusting rod. Microbial carriers for fixing microorganisms are connected to both the first adjusting rod and the second adjusting rod. Microorganisms are cultivated on the microbial carriers.

[0012] The core principle of microbial sewage treatment is to use the metabolic activities of microorganisms to convert organic pollutants in sewage into harmless substances (such as CO 2 、H 2 O, etc.) or stable forms. Microorganisms decompose organic matter through enzyme-catalyzed reactions to obtain energy and synthesize their own substances. Under aerobic conditions, organic matter is completely oxidized to CO 2 and H 2 O; under anaerobic conditions, organic matter is gradually converted into methane, CO 2 , etc.

[0013] However, during use, the microbial carriers are prone to loading pollutants in the sewage, which can then cause blockages, affecting the metabolism of microorganisms and the sewage treatment effect.

[0014] Therefore, the inventor arranges the microbial carriers on the first adjusting rod and the second adjusting rod of the microbial unit. In the original state, the first adjusting rod, the second adjusting rod of the microbial unit, and the microbial carriers thereon are located on a horizontal plane; when the first gear rotates, the first adjusting rod, the second adjusting rod, and the microbial carriers thereon are located on a vertical plane, and the second gear and the third gear are above the first gear and the fourth gear.

[0015] When the first gear rotates, it drives the microbial carriers to move from the horizontal plane to the vertical plane and rotate upward underwater. During the rotation process, through the action of water, the water flow acts on the microbial carriers, which can not only dredge the blocked pollutants on the microbial carriers by using the speed and force of the water flow.

[0016] At the same time, during this process, the flow of water can fully mix the sewage and microorganisms, increasing the contact area between microorganisms and organic matter, thereby improving the decomposition efficiency. Moreover, the water flow scours the surface of the microbial carriers of the microbial carriers, which not only prevents the biofilm from being too thick and causing internal hypoxia, but also promotes the transfer of nutrients to the biofilm.

[0017] In the existing microbial sewage treatment structure, turbulence is usually formed by an aeration device to increase the dissolved oxygen concentration in the water body to meet the metabolic needs of aerobic microorganisms. However, the turbulence formed by the aeration device cannot dredge the pollutants blocked on the microbial carrier rack, and the effect of the water flow scouring on the surface of the microbial carrier is poor, and a good effect cannot be achieved.

[0018] In this system, when the first gear rotates, the first adjusting rod rotates. During the rotation of the second gear on the first adjusting rod, it acts on the third gear to drive the third gear to rotate. During the rotation of the third gear, the second adjusting rod is driven to rotate, realizing a large-scale rotation of the microbial carrier rack on the first adjusting rod and the second adjusting rod, changing from a horizontal state to a vertical state, and rotating from bottom to top underwater. The large-scale rotation can better act on the microbial carrier rack, and at the same time drive the water flow to better scour the surface of the microbial carrier on the microbial carrier rack, achieving a better sewage treatment effect during long-term use.

[0019] Preferably, multiple microbial units can be set in this system and connected in sequence. In two adjacent microbial units, the fourth gear in one microbial unit meshes with the first gear in the other microbial unit. During use, it can contact the water body over a larger area, and moreover, the rotation of the first gear in one microbial unit can drive the first adjusting rods and the second adjusting rods of all microbial units to rotate, with simple and convenient operation.

[0020] Furthermore, the first adjusting rod and the second adjusting rod are arc-shaped. In the original state, the first adjusting rods and the second adjusting rods in two adjacent microbial units form a semi-circle.

[0021] Preferably, this system includes four microbial units, and the four microbial units form a microbial treatment structure. The microbial treatment structure also includes a connecting plate. A circular sliding groove is provided on the connecting plate, and a first sliding rod, a second sliding rod, a combined rod, and a fifth sliding rod are provided on the circular sliding groove. One ends of the first sliding rod, the second sliding rod, the combined rod, and the fifth sliding rod can slide on the circular sliding groove, and the first sliding rod, the second sliding rod, the combined rod, and the fifth sliding rod are respectively connected to the first gear and the fourth gear of two adjacent microbial units;

[0022] The four microbial units are symmetric about the first sliding rod, and moreover, the combined rod includes a third sliding rod and a fourth sliding rod. In the original state, the third sliding rod and the fourth sliding rod are in contact with each other. When the first gear on the first sliding rod rotates, the third sliding rod and the fourth sliding rod separate and are symmetric about the first sliding rod.

[0023] The four microbial units of this system form a circle. On the basis of further expanding the acting area, the structure of this system is more stable. By rotating the first gear on the first sliding rod, the simultaneous action of the four microbial units can be realized, with more stable use and higher efficiency.

[0024] On the other hand, the microbial treatment structure is composed of four microbial units. The system successively includes a number of microbial treatment structures from top to bottom. The connecting plates on the number of microbial treatment structures are connected by connecting rods. The upper end of the connecting rod is connected to the floating island structure. Connecting rods are arranged at both ends of a floating island structure, and microbial treatment structures are successively arranged on the connecting rods from top to bottom. Therefore, underwater, microbial treatment can be carried out in different areas.

[0025] Moreover, the lower end of the connecting rod is provided with an insertion end for inserting into the bottom sludge. The connecting rod can not only connect the microbial treatment structure, but also insert into the bottom sludge to fix the positions of the floating island structure and the microbial treatment structure of the system, preventing them from moving around, and realizing the sewage treatment of specific microorganisms at a fixed location, thereby improving the sewage purification effect.

[0026] In addition, rotating rods are connected to the sides of a number of microbial treatment structures. The rotating rods are meshed with the first gears on the first sliding rods. Therefore, when the rotating rods rotate, the rotating rods drive the first gears on the first sliding rods of all the microbial treatment structures to rotate, making the microbial carrier rack located in a vertical plane.

[0027] Therefore, by rotating the rotating rods, the first adjusting rods and the second adjusting rods of all the microbial treatment structures can be rotated simultaneously. The operation is simple, which can further save costs and reduce the maintenance of equipment.

[0028] Moreover, the plant roots of the floating island structure may be overly dense, blocking the floating island structure, resulting in the sinking of the floating island or a decrease in the purification efficiency. Therefore, the inventor of the present invention has provided a rotating blade at the upper end of the rotating rod for cutting the plant roots in the floating island structure. During the use process, when the rotating rod rotates to drive the microbial carrier rack to rotate, it also drives the rotating blade to rotate to cut the longer plant roots, preventing the plant roots from being overly dense. The system does not require manual regular trimming, and the operation is simpler.

[0029] Furthermore, the connecting rod is made of a transparent material, and a number of first optical fibers are arranged inside the connecting rod. The first optical fibers are used as carriers of photocatalysts (such as nanocrystalline titanium dioxide). Through surface modification techniques (such as π-π bonding), the catalysts are stably attached to the fibers. The first optical fibers transfer ultraviolet or visible light to the underwater reaction area through the principle of total internal reflection, activating the catalysts. The optical fibers introduce light energy into the water and cooperate with ozone to generate free radicals, significantly improving the decomposition efficiency of refractory pollutants.

[0030] Moreover, an ultraviolet lamp layer and a first photocatalyst layer are successively arranged from the inside to the outside of the first sliding rod, the second sliding rod, the combined rod, and the fifth sliding rod.

[0031] An infrared light layer is provided inside the ultraviolet lamp layer, and a composite layer is provided on the infrared light layer. The composite layer is sequentially provided with a second optical fiber and a second photocatalyst layer from inside to outside.

[0032] The infrared LED band can provide a thermal effect at the same time. Through the photothermal conversion of the photocatalytic material or direct water heating, the reaction rate can be increased and the appropriate water temperature can be maintained. Infrared light (especially near-infrared light) has strong penetration in water and is suitable for sewage treatment in deep water environments. Through rare-earth photocatalytic materials (such as β-NaYF 4 :Yb 3+ ,Tm 3+ @TiO 2 ), the infrared light energy can be converted into high-energy ultraviolet / visible light to activate the photocatalyst. Among them, the rare-earth photocatalytic material can be a perovskite-type rare-earth oxide (LaCoO 3 ), or a bimetal-doped material.

[0033] The light source of the ultraviolet lamp layer (365 - 420nm), 365 - 420nm belongs to the range of near-ultraviolet to visible light. Ultraviolet light excites titanium dioxide to generate electron-hole pairs, and graphene, as an electron acceptor, promotes charge separation to generate hydroxyl radicals (·OH) and superoxide radicals (·O 2 - ), decomposing organic matter.

[0034] Moreover, in the original state, the first slide bar, the second slide bar, the combined bar, and the fifth slide bar are below the microbial carrier. Appropriate ultraviolet irradiation can control the excessive proliferation of biofilms on the membrane surface, delay membrane fouling, and reduce the maintenance frequency. The thermal effect of infrared light can adjust the temperature and maintain medium temperature (30 - 40°C) or high temperature (50 - 60°C) conditions in a low-temperature environment, optimizing the metabolic efficiency of mesophilic or thermophilic bacteria groups. For example, it can increase the methane production rate of anaerobic digestion. Infrared radiation may affect the conformation of microbial enzymes through molecular vibration, enhancing their catalytic activity. For example, in a denitrification and phosphorus removal system, infrared assistance can accelerate the absorption of organic matter by polyphosphate-accumulating organisms.

[0035] During use, adjust the ultraviolet intensity according to the water quality (turbidity, suspended solid content) to avoid killing functional microorganisms (such as nitrifying bacteria) by excessive irradiation. The temperature of infrared light needs to be strictly controlled within the suitable range of the target bacteria group (such as 35 - 37°C for denitrification) to prevent local overheating from inactivating the bacteria group.

[0036] Compared with the prior art, the present invention has the following advantages and beneficial effects:

[0037] The present invention relates to a purification and restoration system for urban landscape water bodies. In this system, the microbial carrier rack is arranged on the first adjusting rod and the second adjusting rod of the microbial unit. In the original state, the first adjusting rod, the second adjusting rod of the microbial unit, and the microbial carrier rack thereon are located on a horizontal plane, ensuring that the microbial carrier rack is in large-area contact with the water body. When the first gear rotates, the first adjusting rod, the second adjusting rod, and the microbial carrier rack thereon are located on a vertical plane, and the second gear and the third gear are above the first gear and the fourth gear. Due to the action of water, it acts on the microbial carrier rack, which can not only dredge the blocked pollutants on the microbial carrier rack by utilizing the speed and force of the water flow, but also enable the sewage to be fully mixed with the microorganisms, increasing the contact area between the microorganisms and the organic matter, thereby improving the decomposition efficiency and further enhancing the sewage treatment efficiency.

[0038] Meanwhile, ultraviolet lamps and infrared lamps are arranged on the first sliding rod, the second sliding rod, the combined rod, and the fifth sliding rod of this system. The infrared light and the ultraviolet lamps act on the microbial carrier rack to further improve the sewage treatment effect of the microorganisms.

[0039] Moreover, the power source of this system is the rotating rod. The rotation of the rotating rod can make all the microbial carrier racks rotate and also drive the rotating blades to rotate, automatically cutting the relatively long plant roots regularly to avoid excessive density of the plant roots. This system shares only one power source of the rotating rod, which can effectively save costs, simplify the structure, and improve the usage efficiency. BRIEF DESCRIPTION OF THE DRAWINGS
