Description

Technical Field

[0001] This utility model relates to the technical field of river and lake ecological restoration equipment, specifically a pollution interception and purification device for river and lake ecological restoration. Background Technology

[0002] The accumulation of pollutants has led to the deterioration of water quality in rivers and lakes, eutrophication, excessive algae growth, destruction of the habitat for aquatic organisms, and imbalance of the ecosystem.

[0003] Currently, common methods for river and lake management include physical, chemical, and biological methods. Physical methods, such as dredging floating debris and bottom sediment, can only remove some visible pollutants and are not very effective against dissolved pollutants and microbial contamination. Chemical methods, such as adding chemical agents, can improve water quality to some extent, but may cause secondary pollution and have a negative impact on the ecological environment. Biological methods, such as planting aquatic plants and adding microbial agents, are slow to take effect and have high requirements for environmental conditions. Therefore, we need to propose a pollution interception and purification device for the ecological restoration of rivers and lakes. Utility Model Content

[0004] The purpose of this invention is to provide a pollution interception and purification device for the ecological restoration of rivers and lakes. This device employs multiple methods to overcome the shortcomings of physical methods in dealing with dissolved and microbial pollution, thereby achieving deep purification of water bodies, improving water quality, and solving the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A pollution interception and purification device for ecological restoration of rivers and lakes, comprising:

[0007] Several sets of U-shaped seats and connecting seats are set in the river channel;

[0008] Adjacent U-shaped seats are connected by connecting seats. A purification slot is provided in the U-shaped opening of the U-shaped seat. A purification plate for purifying river water is inserted into the purification slot. The purification medium of the purification plate includes a filter layer, a biological filler layer and an adsorption layer.

[0009] The U-shaped opening of the U-shaped seat has protective slots on both sides of the purification slot. Protective plates, which are metal wire mesh plates, are inserted into the protective slots to intercept garbage and foreign objects in the river water.

[0010] Preferably, the cross-section of the U-shaped seat is T-shaped to provide higher stability and impact resistance, and the U-shaped seat has a transition slope towards the inner U-shaped opening.

[0011] Preferably, the two end faces of the connecting seat are respectively adapted to the end faces of two adjacent sets of U-shaped seats, and the water-facing surfaces on both outer sides of the connecting seat are provided with diversion protrusions, which are cone-shaped to divert river water to the U-shaped seats on both sides.

[0012] Preferably, the bottom of the U-shaped seat is provided with a first positioning stake for insertion into the bottom of the river channel, and the bottom of the connecting seat is provided with a second positioning stake for insertion into the bottom of the river channel.

[0013] Preferably, the biological filler layer is a type of large-pore filter material such as polyurethane foam, volcanic rock, or ceramsite with a large number of microbial communities attached to its surface. The pore size ranges from 0.5 to 2 mm, which can decompose and transform organic matter in the water, thereby reducing the chemical oxygen demand (COD) and biochemical oxygen demand (BOD) of the water.

[0014] Preferably, the filter layer uses a granular filter media made of a mixture of quartz sand and gravel, with a particle size of 0.5-2 mm. It can trap tiny particles through the gaps between the particles, thereby removing fine suspended solids and some colloidal substances from the water.

[0015] Preferably, the adsorption layer uses activated carbon or zeolite adsorption materials, which can adsorb pollutants such as heavy metal ions, ammonia nitrogen, and phosphorus in the water, thereby further improving the water purification effect.

[0016] Preferably, both ends of the connecting seat are provided with T-shaped connecting grooves, and both ends of the U-shaped seat are provided with T-shaped connecting blocks, which are compatible with the connecting grooves.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] 1. Comprehensive and High-Efficiency Purification: The purification plate is equipped with a filter layer, a biological packing layer, and an adsorption layer, which respectively remove various pollutants in the water, such as fine suspended solids, colloidal substances, organic matter, heavy metal ions, ammonia nitrogen, and phosphorus. The filter layer traps tiny particles, the biological packing layer decomposes and transforms organic matter, and the adsorption layer adsorbs harmful ions and pollutants. This multi-pronged approach overcomes the shortcomings of physical methods in dealing with dissolved and microbial contamination, achieving deep purification of the water and improving water quality.

[0019] 2. Avoid secondary pollution: Compared with the secondary pollution that may be generated by chemical addition of agents, the biological treatment and adsorption methods used in this device utilize natural or environmentally friendly materials, do not introduce new harmful chemicals, are environmentally friendly, will not have a negative impact on river and lake ecosystems, and are in line with the sustainable development concept of ecological restoration.

[0020] 3. Effective interception of foreign objects: The protective plate is made of metal wire mesh and is set in the protective slot of the U-shaped seat. It can effectively intercept garbage and foreign objects in the river water, prevent them from clogging or damaging the purification plate, and ensure the normal operation of the purification device. At the same time, it intercepts large particles of garbage first, reducing the processing burden of the subsequent purification plate.

[0021] 4. Both the purification plate and the protective plate are installed in the corresponding slots of the U-shaped base by plugging in. This modular design makes it easy to disassemble and replace. When the purification medium of the purification plate reaches saturation or the protective plate is blocked by garbage, it can be directly removed for replacement or cleaning. The operation is simple, reducing maintenance costs and difficulty, and improving the practicality of the device. Attached Figure Description

[0027] 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.

[0028] Please see Figure 1-4 This utility model provides a technical solution:

[0029] A pollution interception and purification device for ecological restoration of rivers and lakes, comprising:

[0030] Several sets of U-shaped seats 1 and connecting seats 2 are set in the river channel; adjacent U-shaped seats 1 are connected by connecting seats 2. A purification slot 6 is opened in the U-shaped opening of the U-shaped seat 1. A purification plate 4 for purifying river water is inserted into the purification slot 6. The purification medium of the purification plate 4 includes a filter layer 401, a biological filler layer 402 and an adsorption layer 403. A protective slot 5 is opened on both sides of the purification slot 6 in the U-shaped opening of the U-shaped seat 1. A protective plate 3 for intercepting garbage and foreign objects in the river water is inserted into the protective slot 5. The protective plate 3 is a metal wire mesh plate.

[0031] By setting up several sets of U-shaped seats in the river channel, adjacent U-shaped seats are connected by connecting seats 2 to form a continuous purification and interception system. The protective plate 3 is inserted into the protective slot 5 of the U-shaped seat, and the metal wire mesh structure is used to intercept garbage and foreign objects in the river water. The purification plate 4 is inserted into the purification slot 6. During the flow of the river water, it passes through the filter layer 401, biological filler layer 402 and adsorption layer 403 of the purification plate 4 in sequence, so as to remove pollutants such as fine suspended solids, organic matter and heavy metal ions.

[0032] In summary, the combined design of the U-shaped base and the connecting base 2 allows the number of sets of the device to be flexibly set according to the actual conditions of the river. Adjacent U-shaped bases are connected by the connecting base 2, which facilitates installation in the river. At the same time, the purification plate 4 and the protective plate 3 are respectively inserted into the purification slot 6 and the protective slot 5. This plug-in design facilitates the replacement and cleaning of the purification plate 4 and the protective plate 3, reducing maintenance costs and difficulties. The protective plate 3 effectively intercepts garbage and foreign objects, preventing them from clogging the purification plate 4 and reducing the processing load of the purification plate 4. The purification plate 4 integrates multiple purification media to purify the water from different levels, making up for the shortcomings of traditional physical, chemical and biological treatment methods, and realizing the comprehensive treatment of pollutants in rivers and lakes.

[0033] Specifically, please refer to Figure 3 :

[0034] The biological filter media layer 402 is a large-pore filter medium, such as polyurethane foam, volcanic rock, or ceramsite, with a surface covered with a large number of microbial communities. The pore size ranges from 0.5 to 2 mm, enabling it to decompose and transform organic matter in the water, reducing the chemical oxygen demand (COD) and biochemical oxygen demand (BOD). The filter layer 401 uses a granular filter medium composed of a mixture of quartz sand and gravel, with a particle size of 0.5 to 2 mm. It traps tiny particles through the gaps between the particles, removing fine suspended solids and some colloidal substances from the water. The adsorption layer 403 uses activated carbon or zeolite adsorption materials, capable of adsorbing pollutants such as heavy metal ions, ammonia nitrogen, and phosphorus in the water, further improving the water purification effect.

[0035] Filter layer 401 uses granular filter media made of a mixture of quartz sand and gravel. Utilizing the interparticle gaps formed by particles with a diameter of 0.5-2 mm, it intercepts and blocks tiny particles, separating fine suspended solids and some colloidal substances from the river water. The biological packing material uses large-pore filter media (pore size 0.5-2 mm) such as polyurethane foam, volcanic rock, or ceramsite. Under suitable conditions, a large number of microbial communities attached to its surface decompose and transform organic matter in the water, converting complex organic matter into simple inorganic matter, thereby reducing the chemical oxygen demand (COD) and biochemical oxygen demand (BOD) of the water. Adsorption layer 403 uses adsorption materials such as activated carbon or zeolite. Relying on its porous structure and surface activity, it adsorbs pollutants such as heavy metal ions, ammonia nitrogen, and phosphorus in the water, further purifying the water quality.

[0036] In general, the various purification media have clear division of labor and work together. The filter layer 401 performs preliminary filtration, the biological packing layer 402 treats organic matter specifically, and the adsorption layer 403 enhances the removal of harmful ions and pollutants, thereby achieving efficient purification of various pollutants in river and lake waters, improving water quality, and promoting ecological restoration.

[0037] Please see Figure 1 , 3 And 4:

[0038] The U-shaped seat 1 has a T-shaped cross-section for high stability and impact resistance. A transition slope is provided inwards towards the U-shaped opening of the U-shaped seat 1. The two end faces of the connecting seat 2 are respectively adapted to the end faces of the two adjacent sets of U-shaped seats 1. Diversion protrusions 11 are provided on the water-facing surfaces of both outer sides of the connecting seat 2. These diversion protrusions 11 are conical in shape, diverting river water to the U-shaped seats 1 on both sides. A first positioning stake 7 for insertion into the riverbed is provided at the bottom of the U-shaped seat 1, and a second positioning stake 8 for insertion into the riverbed is provided at the bottom of the connecting seat 2. T-shaped connecting grooves 10 are provided on both end faces of the connecting seat 2, and T-shaped connecting blocks 9 are provided on both end faces of the U-shaped seat 1. The connecting blocks 9 and the connecting grooves 10 are adapted to each other.

[0039] The U-shaped seat has a T-shaped cross-section. This structural design increases the contact area and stability with the riverbed, while the transition slope facilitates the smooth flow of river water into the purification slot 6 and the protection slot 5. The two end faces of the connecting seat 2 are adapted to the end faces of the U-shaped seat, and a stable connection is achieved through the cooperation of the T-shaped connecting block 9 and the connecting groove 10. The diversion protrusion 11 on the water-facing side of the connecting seat 2 is conical, which can guide the river water to the two U-shaped seats on both sides and disperse the impact force of the water flow. The first positioning pile 7 and the second positioning pile 8 at the bottom of the U-shaped seat and the connecting seat 2 are inserted into the riverbed to further fix the position of the device.

[0040] In summary, the T-shaped and U-shaped bases and positioning piles enhance the stability and impact resistance of the device in the river flow, preventing the device from shifting or being damaged; the transition slope and diversion protrusion 11 optimize the water flow path, allowing the river water to flow evenly through the purification plate 4 and the protective plate 3, improving purification and interception efficiency; the cooperation between the connecting block 9 and the connecting groove 10 facilitates the installation, disassembly and expansion of the device, and the length and scale of the device can be flexibly adjusted according to the actual conditions of the river.
