Description

Technical Field

[0001] The utility model belongs to the field of river channel restoration, in particular to a biological module for injecting slow-release oxygenation materials. Background Art

[0002] my country's industrialization process was relatively late, and river pollution has only become a problem in recent decades. Research has revealed that some river improvements are failing to maintain their effectiveness over time, posing a significant risk of reversion to black and odorous water. Stagnant water flow, coupled with insufficient dissolved oxygen (DO), impairs the water's self-purification capacity, preventing the effective degradation of these exogenous pollutants. Furthermore, severe endogenous pollution is contributing to further deterioration in water quality. These issues present significant challenges in the treatment of polluted waters.

[0003] Currently, the main remediation technologies for black and odorous water bodies can be categorized according to their principles: physical remediation, chemical remediation, phytoremediation, and microbial remediation. Chemical remediation typically utilizes chemical oxygenators, compounds that release oxygen upon reaction with water or through self-decomposition. When used in water remediation, chemical oxygenators must maintain a sufficiently long oxygen release period to meet the DO requirements of aerobic microbial metabolic activity. Therefore, the oxygen release rate is a crucial characteristic determining their effectiveness. However, most commonly used oxygenators suffer from excessively rapid oxygen release rates. Utility Model Content

[0004] In light of this, the present invention proposes a bio-module that deploys slow-release oxygenation materials to improve water quality below the surface and reduce the rate of oxygen release, addressing the problem of excessively rapid oxygen release associated with most oxygenators. Furthermore, the bio-wall improves the survival rate of submerged plants, and the submerged plants within the bio-wall increase the area of submerged plants within the waters.

[0005] In order to achieve the above-mentioned purpose, the technical solution of the utility model is achieved as follows:

[0006] A biological module for injecting slow-release oxygenation material comprises a frame, a biological wall, a base plate, a cover plate and an injection port, wherein the biological wall is arranged on the side of the frame and is used to grow submerged plants; the base plate is arranged at the bottom of the frame and has multiple through holes evenly arranged on the base plate; the cover plate is arranged on the top of the frame and has an injection port for injecting slow-release oxygenation material; the frame and the biological wall, base plate and cover plate arranged on the frame form a cavity for placing the slow-release oxygenation material.

[0007] Furthermore, the frame is in the shape of a cube or a cuboid, and biological walls are respectively provided on the four sides of the frame, and the biological walls are made of diatomaceous earth blocks.

[0008] Furthermore, the frame includes an upper frame, a lower frame and side frames; the upper frame and the lower frame are square and arranged parallel to each other; the four corners of the upper frame and the lower frame are respectively connected to the side frames.

[0009] Furthermore, the biological wall is detachably connected to the frame by bolts.

[0010] Furthermore, the diameter of the through hole on the bottom plate is 5 mm to 8 mm.

[0011] Furthermore, the bottom plate has a length of 30 cm, a width of 30 cm, and a thickness of 3 mm.

[0012] Furthermore, the slow-release oxygen-enhancing material includes a chemical oxygenator.

[0013] Furthermore, the sustained-release oxygen-enhancing material comprises a chemical oxygen-enhancing tablet compressed by a mold having a diameter of 6 mm.

[0014] Compared with the prior art, the biomodule for injecting slow-release oxygenation material described in the present invention has the following advantages:

[0015] The present invention discloses a biomodule for injecting slow-release oxygenating materials. The biomodule comprises a frame, a biowall, a base plate, and a cover plate mounted on the frame, forming a submerged plant planting rack. The frame comprises a cavity for placing the slow-release oxygenating material.

[0023] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features therein can be combined with each other.

[0024] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0025] A biological module for injecting slow-release oxygenation material comprises a frame 1, a biological wall 2, a bottom plate 11, a cover plate 5 and a injection port 4. The biological wall 2 is arranged on the side of the frame 1, and the biological wall 2 is used to plant submerged plants. Submerged plants are planted on the biological wall 2; a bottom plate 11 is arranged at the bottom of the frame 1, and a plurality of through holes 13 are evenly arranged on the bottom plate 11; a cover plate 5 is arranged on the top of the frame 1, and a injection port 4 for injecting slow-release oxygenation material is opened on the cover plate 5; the frame 1 and the biological wall 2, bottom plate 11 and cover plate 5 arranged on the frame 1 form a accommodating cavity 7 for placing the slow-release oxygenation material.

[0026] A biomodule for injecting slow-release oxygenating materials. The biomodule's frame 1, biowall 2, bottom plate 11, and cover plate 5 disposed on the frame 1 form a submerged plant planting rack, with submerged plants planted on the biowall 2. The biomodule's frame 1, biowall 2, bottom plate 11, and cover plate 5 internally form a cavity 7 for placing the slow-release oxygenating material. During use, the slow-release oxygenating material is injected into the injection port 4, and the biomodule is placed below the water surface, preferably 30 cm below the water surface. The slow-release oxygenating material can improve the water quality below the water surface. The slow-release oxygenating material is placed in the cavity 7 and isolated from the water by the submerged plants, bottom plate 11, and cover plate 5, thereby reducing the oxygen release rate. At the same time, the biowall 2 can improve the survival rate of the submerged plants, and the submerged plants 3 on the biowall 2 can increase the planting area of submerged plants in the water area.

[0027] It's important to note that the most widely studied preparation methods for oxygen-releasing materials currently use common embedding materials such as concrete, stearic acid, sodium alginate (SA), polyvinyl alcohol (PVA), and polyethylene glycol (PEG). River restoration results show that the use of this oxygen-releasing material reduced TP concentration in the water by 79.6%, effectively confining the easily released weakly adsorbed and iron-bound phosphorus in the sediment.

[0028] like Figure 2 、 Figure 3As shown, the frame 1 is in the shape of a cube or a cuboid, and biological walls 2 are respectively set on the four sides of the frame 1. The biological walls 2 are made of diatomaceous earth blocks 12. The diatomaceous earth blocks are not easily dispersed in the planting frame and are efficient fertilizers for submerged plants, promoting the growth of aquatic plants.

[0029] like Figure 2 As shown, the frame 1 includes an upper frame 8, a lower frame 10, and side frames 9. The upper and lower frames 8, 10 are square and arranged parallel to each other. The four corners of the upper and lower frames 8, 10 are connected to the side frames 9. The biowall 2 is detachably connected to the frame 1 via bolts 6. The detachable biowall 2 facilitates the timely replacement of dead submerged plants with new ones.

[0030] like Figure 4 As shown, preferably, the diameter of the through hole 13 on the bottom plate 11 is 5 mm to 8 mm. The bottom plate 11 is 30 cm long, 30 cm wide, and 3 mm thick. A suitable oxygen release rate is provided through the bottom plate and the through holes on the bottom plate. The slow-release oxygen-enhancing material includes a chemical oxygenator. Currently, common chemical oxygenators include hydrogen peroxide (H2O2), sodium percarbonate (2Na2CO3·3H2O2), magnesium peroxide (MgO2), and CaO2. The slow-release oxygen-enhancing material includes a chemical oxygenation tablet pressed by a mold with a diameter of 6 mm. The chemical oxygenation tablet is easy to put in from the feeding port 4, making it more convenient to put in.

[0031] A biological module for injecting slow-release oxygenating materials can significantly improve water quality by arranging a submerged plant planting rack and a cavity for placing the slow-release oxygenating material. The transparency of the improved landscape water is significantly improved, and the COD content, ammonia nitrogen content, total nitrogen content and total phosphorus content of the improved landscape water are all significantly reduced. In addition, the entire biological module plus the submerged plant planting rack form a gradient with the ecosystem at the bottom of the target water body, which improves the self-purification capacity of the target water body and promotes the healthy development of the water ecosystem.

[0032] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
