Description

Technical Field

[0001] This utility model relates to the field of river management technology, specifically a green device for a river water self-purification system. Background Technology

[0002] In the field of river ecological management, improving the self-purification capacity of water bodies is the core requirement for improving water environment quality. Natural rivers are often affected by factors such as water flow conditions and pollutant input, and often face problems such as eutrophication and biodiversity decline. Artificial water purification technology has become a key means of restoring river ecology. By constructing a natural-like ecosystem and combining material technology and microbial technology, the ability of water bodies to degrade pollutants has been enhanced, which has become the mainstream direction of river management.

[0003] Existing technologies of this kind have obvious limitations. For rivers with large water flow, the water flow speed is too fast, making it difficult for microorganisms to attach and form a stable community, thus failing to effectively play a purification role. Traditional artificial membrane materials have low adsorption rates and lack targeted biological cultivation measures, making it difficult to achieve efficient removal of pollutants. At the same time, most technologies rely on a single purification path and fail to form a synergistic effect. They cannot provide a continuous and stable living environment for microorganisms, nor can they quickly improve the dissolved oxygen state of the water body, resulting in poor purification effect and insufficient stability, which cannot meet the long-term self-purification needs of rivers. To address this, we propose a green device for a river water self-purification system. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a green device for a river water self-purification system, which solves the aforementioned problems.

[0005] To achieve the above-mentioned objectives, this utility model provides the following technical solution: a green device for a river water self-purification system, comprising:

[0006] A river channel, the surface of which is water;

[0007] The Step-Pool ecological unit is set inside the river channel. The Step-Pool ecological unit includes gravel, floating islands and microbial film groups. The gravel is located at the bottom of the river channel and the surface of the river channel is water. The floating islands float on the water surface and multiple linearly distributed microbial film groups are provided at the bottom of the river channel.

[0008] A microbial enhancement unit is added inside the Step-Pool ecological unit. The microbial enhancement unit is composed of a highly efficient ecological composite self-cleaning bacterial community, and the bacterial community is attached to the surface of the microbial module.

[0009] A solar-powered nanobubble aerator is installed on the water surface to release oxygen-rich micro-nano bubbles into the water body inside the river channel.

[0010] Preferably, the microbial membrane module includes a frame and membrane spheres. The frame has a rectangular tube frame structure and is made of white PVC material. Membrane spheres are placed inside the frame, and adjacent membrane spheres are connected by a string.

[0011] Preferably, the surface of the membrane sphere is provided with a high specific surface area membrane, and the high specific surface area membrane is a carbon fiber biofilm.

[0016] Compared with the prior art, this utility model provides a green device for a river water self-purification system, which has the following beneficial effects:

[0017] This green self-purification system for river water achieves a synergistic effect of ecological and efficient river purification. The three-dimensional habitat constructed by the step-pool ecological unit's gravel and high specific surface area membrane, combined with the aquatic plants on the floating island, provides a stable attachment and survival space for microorganisms.

It enhances biodiversity through its natural-like structure and strengthens the pollutant degradation capacity through the synergistic effect of microorganisms and bubbles. It can remove pollutants such as organic matter and nutrients from the water, reduce endogenous pollution in the bottom sediment, maintain the ecological balance of the water body in the long term, and achieve a green, environmentally friendly, stable, and lasting purification effect.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-2 This utility model provides a technical solution;

[0023] A green device for a river water self-purification system includes:

[0024] River channel 1, the surface of river channel 1 is water surface 3;

[0025] The Step-Pool ecological unit is set inside the river channel 1. The Step-Pool ecological unit includes gravel 2, floating islands 7 and microbial membrane groups. The gravel 2 is located at the bottom of the river channel 1, and the surface of the river channel 1 is the water surface 3. The floating islands 7 float on the surface of the water surface 3. Multiple linearly distributed microbial membrane groups are set at the bottom of the river channel 1 to slow down the water flow speed, prolong the hydraulic residence time and provide an attachment carrier for microorganisms.

[0026] The microbial enhancement unit is added inside the Step-Pool ecological unit. The microbial enhancement unit is composed of highly efficient ecological composite self-purifying bacteria, and the bacteria are attached to the surface of the microbial module to degrade organic pollutants and eutrophic substances in the water.

[0027] A solar-powered nanobubble aerator 4 is installed on the surface of the water 3 to release micro-nano bubbles 8 rich in dissolved oxygen into the water body inside the river channel 1.

[0028] Furthermore, the microbial membrane module includes a frame 5 and membrane balls 6. The frame 5 has a rectangular tube frame structure and is made of white PVC material. Membrane balls 6 are installed inside the frame 5. Adjacent membrane balls 6 are connected by ropes. The microbial membrane module provides a stable attachment position for the highly efficient ecological composite self-cleaning bacteria community, as well as slows down the water flow speed and extends the hydraulic residence time, providing the necessary time for the bacteria community to attach.

[0029] Furthermore, the surface of the membrane sphere 6 is provided with a high specific surface area membrane 10, which is a carbon fiber biofilm sheet. The average pollutant removal rate of the high specific surface area membrane 10 is not less than 93%. In a natural river channel 1 with a certain drop, the carbon biofilm of the high specific surface area membrane 10, together with the step structure composed of gravel 2, can increase the resistance of the river water and prolong the residence time of the river water, allowing the river water to fully shear, transfer mass, mix, and oxygenate in the biofilm area. If the river water has a certain amount of organic pollution, a large number of microorganisms will be attached to the surface of the high specific surface area membrane 10, which, together with the highly efficient ecological composite self-purifying bacteria, form a microbial film 11. When the river water passes through the microbial film 11, a large amount of organic matter in the river water is reduced.

[0030] Furthermore, the surface of the floating island 7 is equipped with aquatic plants 9. The aquatic plants 9 purify the water through root adsorption and microbial degradation. The microorganisms in the plant rhizosphere environment can remove pollutants such as organic matter, ammonia nitrogen, and suspended particulate matter from the sewage, thereby improving the self-purification capacity of the river.

[0031] Furthermore, the highly efficient ecological composite self-cleaning bacteria attach to the surface of the high specific surface area membrane 10, forming a microbial film 11.

[0032] Furthermore, the highly efficient ecological composite self-purifying bacterial community includes at least three of the following: aerobic bacteria, anaerobic bacteria, facultative bacteria, photosynthetic bacteria, and nitrifying / denitrifying bacteria. It is used to construct a complete aquatic ecosystem that includes decomposers, producers, and consumers. When a certain amount of wastewater enters this ecosystem, the organic pollutants are not only degraded and purified by bacteria and fungi, but the final products of their degradation, some inorganic compounds, serve as carbon, nitrogen, and phosphorus sources. Using solar energy as the initial energy source, they participate in the metabolic processes in the food web and migrate and transform step by step from low trophic levels to high trophic levels, eventually transforming into higher life products such as aquatic plants and aquatic animals. This maintains the overall ecological balance of the water body, enhances the aesthetics and naturalness of the waterscape, and achieves the goal of preventing eutrophication of the water body.

[0033] Furthermore, the micro-nano bubbles 8 have a diameter between 100nm and 10μm. They possess a large specific surface area, exhibiting exceptional gas dissolution capacity, greatly accelerating the reaction rate between gas and liquid. Their slow ascent speed results in a long residence time in water. The negatively charged surface provides excellent adsorption for oils and suspended solids in wastewater. Self-pressurization and dissolution generate a large number of free radicals, resulting in strong oxidizing and bactericidal properties. The micro-nano bubbles 8 possess extremely high bubble density and lateral diffusivity, exhibiting significant physiological activity. They promote biological purification. When aerating polluted, oxygen-deficient waters with micro-nano bubbles, the consumption of dissolved oxygen within the bubbles continuously replenishes the water with active oxygen, enhancing the biological activity of aerobic microorganisms, plankton, and aquatic animals. This accelerates the biodegradation of pollutants in the water and sediment, achieving water purification. Furthermore, their oxidizing properties decompose many organic pollutants, reducing endogenous pollution in the sediment.

[0034] Working Principle: The green device for the river water self-purification system is installed correctly according to the diagram. This device integrates a high specific surface area membrane 10 (microbial membrane group), a highly efficient ecological composite self-purifying bacterial community, and a solar-powered nanobubble aerator 4 into a three-in-one system. This efficiently degrades eutrophic water and achieves long-term self-purification. The microbial membrane group is located in the Step-Pool ecological unit. Furthermore, the gravel 2 at the bottom of the river channel 1, in conjunction with the frame 5 containing the membrane balls 6, forms a natural-looking stepped structure, increasing water flow resistance and extending the hydraulic retention time. The membrane balls 6... The high specific surface area membrane 10 on the surface provides a carrier for microorganisms to attach to, and together with the added highly efficient ecological composite self-purifying bacteria, a microbial membrane 11 is formed. The floating islands 7 and the aquatic plants 9 on the surface of the water enhance purification through root adsorption and rhizosphere microbial degradation. The solar-powered nanobubble aerator 4 placed on the surface of the water continuously releases micro-nano bubbles 8. Its high dissolved oxygen characteristics provide active oxygen for the bacteria in the microbial membrane 11, enhancing biological activity. At the same time, the bubbles adsorb suspended matter and decompose recalcitrant organic matter. The three work together to achieve efficient degradation of pollutants and the construction of an ecosystem.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
