Description

Technical Field

[0001] This utility model relates to the field of river management technology, specifically to a treatment device for river management. Background Technology

[0002] Currently, my country's river management efforts have shifted from the traditional single objective of flood control and drainage to a comprehensive approach that integrates water security, water ecology, water environment, and water culture. This transformation aims to achieve the goal of building happy rivers and lakes characterized by "safe rivers and tranquil lakes, green banks and beautiful scenery, and harmony between people and water."

[0003] Currently, many cities, especially older urban areas, commonly suffer from inadequate sewage pipe networks and incomplete separation of rainwater and sewage. Domestic sewage and industrial wastewater are often discharged directly into rivers through rainwater pipe networks. Combined sewer systems experience overflow pollution during the rainy season, and issues such as misconnections and mixed connections make it difficult to completely eradicate pollution, and the treatment process is systemic and recurring. Treating black and odorous water bodies requires a multi-pronged approach, including interception of sewage, dredging, water circulation, and ecological restoration. However, even after treatment, if a stable ecological water supply is lacking, resulting in poor self-purification capacity, or if a sound long-term management mechanism is inadequate, the water body can easily revert to its black and odorous state. Utility Model Content

[0004] The purpose of this invention is to address the problems existing in the prior art by providing a treatment device for river management. This device achieves continuous and effective river management and stable river purification capabilities by installing photovoltaic panels and energy storage devices on floating islands and filling the biological treatment device with filler.

[0005] To achieve the above objectives, the technical solution provided by this utility model is as follows: A treatment device for river management includes a floating island, photovoltaic panels, aquatic plants, an energy storage device, an aeration fan, and a biological treatment device. The photovoltaic panels, energy storage device, and aeration fan are all installed on the floating island. The aquatic plants are planted on the floating island. The biological treatment device is located below the floating island and is filled with packing material.

[0006] Preferably, the biological treatment device is fixed to the bottom of the floating island by a channel steel support.

[0007] Furthermore, the channel steel support consists of three or more pieces.

[0008] Preferably, all surfaces of the biological treatment device are composed of perforated grid plates. Further, the diameter of the openings in the perforated grid plates is 15-20 mm, and the center-to-center distance between the openings is 20-30 mm.

[0009] Preferably, an aeration disc is provided at the bottom of the biological treatment device. Further, the diameter of the aeration disc is 215-300 mm.

[0010] Furthermore, the aeration disc is connected to the aeration blower via an aeration pipe.

[0011] Preferably, the photovoltaic panel generates electricity and stores it in an energy storage device, which provides kinetic energy to the aeration blower.

[0012] Preferably, the filler has a diameter of 20-25 mm, a height of 8-10 mm, and a density of 0.95-0.98 g / cm³. 3 The filling amount of the packing material is 20-40% of the volume of the biological treatment device.

[0013] Compared with the prior art, this utility model has the following advantages: First, the electricity generated by the photovoltaic power generation system, which includes photovoltaic panels and energy storage devices, powers the aeration blowers of the biological treatment device, enabling sustainable and effective river management without the need for kinetic energy consumption.

[0014] Secondly, by filling the biological treatment device with 20-40% volume of biological packing material, river-purifying microorganisms can quickly attach to the packing material, enhancing the river purification system. Furthermore, the packing material, after attaching microorganisms, reaches a concentration close to 1 g / cm³. 3 When the photovoltaic power generation system can no longer provide continuous kinetic energy, the filler can still tumble in the biological treatment device under the action of water flow, providing a suitable growth environment for microorganisms and stabilizing the river purification capacity.

[0015] Third, when the photovoltaic power generation system stores excessive energy, the aeration rate of the aeration blowers can be increased, which can effectively increase the dissolved oxygen content of the river water and curb the formation of black and odorous water. At the same time, the aeration blowers are installed above the floating islands for easy maintenance.

[0016] Fourth, aquatic plants are planted in the gaps on the floating islands, which can purify the water and enhance the river landscape, thus beautifying the river environment while managing the river. Attached Figure Description

[0025] Reference Figure 1 , Figure 1This diagram illustrates the structure of a treatment device for river management according to one embodiment of the present invention. The river management system provided in this embodiment includes a floating island 1, with aquatic plants 3 planted in the gaps above the island to purify the water. A photovoltaic power generation system, including photovoltaic panels 2 and an energy storage device 8, and an aeration fan 9 are also installed. The photovoltaic panels 2 generate electricity, which is stored in the energy storage device 8. The energy storage device 8 provides kinetic energy to the aeration fan 9, which in turn provides air to the biological treatment device 5. The floating island is made of stainless steel with expanded polystyrene foam. Stainless steel embedded parts are pre-embedded below the floating island. One end of a channel steel support 10 is welded to the stainless steel embedded parts and fixed below the floating island 1, while the other end is fixed to the biological treatment device 5. The biological treatment device 5 is fixed below the floating island 1 via the channel steel support 10. The biological treatment device contains packing material 4 with attached microorganisms. River-purifying microorganisms can attach to the packing material, which tumbles under the influence of air, comprehensively purifying the river water. The filling material 4 is used to fill 20-40% of the volume of the biological treatment device 5. The treatment device is used to treat river channels. A photovoltaic power generation system is installed above the floating island; the photovoltaic panels convert solar energy into electricity, which is then stored in an energy storage device.

[0026] In one embodiment, the floating island 1 floats on the surface of the river water.

[0027] In one embodiment, reference Figure 4 , Figure 4 The diagram shows the structure of the packing material 4, which has a diameter of 20-25 mm, a height of 8-10 mm, and a density of 0.95-0.98 g / cm³. 3 .

[0028] In one embodiment, the channel steel support member 10 is three or more, preferably four.

[0029] In one embodiment, reference Figure 2-3 All surfaces of the biological treatment device 5 are composed of perforated grid plates 11. Furthermore, the diameter of the openings in the perforated grid plates 11 is 15-20 mm, and the center-to-center distance between the openings is 20-30 mm.

[0030] In one embodiment, an aeration disc 6 is provided at the bottom of the biological treatment device 5. Further, the aeration disc 6 is connected to an aeration blower 9 via an aeration pipe 7. The diameter of the aeration disc 6 is 215-300 mm.

[0031] Furthermore, the aeration blower 9 provides micron-sized air bubbles to the biological treatment device 5 through the aeration pipe 7 and aeration disc 6, increasing the dissolved oxygen in the river water. The aeration blower is installed above the floating island for easy maintenance. A photovoltaic panel is also installed above the floating island; the photovoltaic panel converts solar energy into electrical energy, which is stored in an energy storage device to continuously provide power to the aeration blower.

[0032] The river treatment device works as follows: photovoltaic panels above the floating island convert solar energy into electricity under sunlight, which is stored in an energy storage device. This electricity continuously and stably powers the aeration blowers, ensuring that they can operate around the clock under sufficient sunlight. The aeration blowers provide micron-sized air bubbles to the biological treatment device. The packing material containing microorganisms inside the biological treatment device tumbles freely under the influence of microbubbles and water flow, enhancing the microorganisms' ability to treat the river water. The biological treatment device is surrounded by perforated plates, allowing river water to flow continuously within it. Installing it in one location allows for continuous purification of the river water, resulting in high dissolved oxygen levels and promoting the restoration of the river's self-purification capacity. Simultaneously, aquatic plants planted above the floating island continuously purify the river water, requiring only one or two harvesting and sowing cycles per year. The entire river treatment device requires virtually no maintenance or energy and also serves as a landscape feature for the river.

[0033] This utility model provides a concept and method for a treatment device used in river management. Many methods and approaches exist for implementing this technical solution; the above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. All components not explicitly stated in this embodiment can be implemented using existing technology.
