Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of water purification, and in particular relates to a water purification bed suitable for slightly polluted water bodies. Background Art
[0002] At present, water purification beds are widely used in the comprehensive management of eutrophic water bodies as a practical technology for in-situ control and ecological restoration of water bodies, due to their advantages of improving landscape, restoring ecology, and purifying pollution. The existing aeration effect is poor, and the water bodies in the area are unevenly mixed, resulting in poor purification effect of water purification beds. Utility Model Content
[0003] The utility model aims to solve one of the technical problems in the related art at least to a certain extent.
[0004] To this end, the technical solution adopted by the utility model is: a water purification bed suitable for slightly polluted water bodies, including an external frame and an internal frame arranged inside the external frame, a slide rail and two moving wheels are arranged between the upper part of the external frame and the upper part of the internal frame, the two moving wheels can move on the slide rail, a watertight curtain is arranged between the two moving wheels, the two ends of the watertight curtain are respectively connected to the two moving wheels, a layer of flexible material mesh cage is arranged in the internal frame, a plurality of polyurethane filler bodies are placed in the mesh cage, an aeration system is arranged under the internal frame, the aeration system includes a micro-nano aeration main pipe, one or more aeration disc assemblies are arranged on the micro-nano aeration main pipe, and the aeration disc assembly is connected to the micro-nano aeration main pipe through a first aeration branch pipe.
[0005] Furthermore, the aeration plate assembly includes one or more aeration plates.
[0006] Preferably, the aeration disc assembly includes three aeration discs, which are arranged in sequence along the width direction of the internal frame, and two adjacent aeration discs are connected by a second aeration branch pipe, and any one of the two aeration discs located at the edge is connected to the micro-nano aeration main pipe through a first aeration branch pipe.
[0007] Furthermore, the outer frame and the inner frame are both in the shape of a rectangular parallelepiped.
[0008] Furthermore, the total volume of the plurality of polyurethane filler bodies accounts for 70% to 80% of the internal volume of the internal frame.
[0009] Compared with the prior art, the utility model has the following beneficial effects: the utility model can form a semi-enclosed box-type structure, and the movable structures of slide rails, moving wheels and impermeable curtains are adopted on the four sides, which can be opened and closed. The internal fixed volume accounts for 70-80% of the polyurethane filler, and an aeration system is installed at the bottom, and the aeration system is supplied with air by a fan. The aeration system provides a large amount of dissolved oxygen to the interior of the internal frame. In the river channel with frequent water exchange and fast flow rate, the impermeable curtain is completely closed to close the four sides. After the aeration system at the bottom starts aeration, a surrounding airflow will be formed in the cross section of the river channel. After the aeration system is turned on, a discontinuous discontinuity surface is formed between the two fluids of gas and water. Under the interference of the aeration disk, the intermittent surface loses stability and generates a vortex. The vortex draws the microorganisms in the purification bed into the jet toward the water surface, where part of the gas escapes from the water surface, and the other part of the gas mixes with the microorganisms and sinks to the sides of the purification bed. Then, it is sucked into the purification bed again by the negative pressure generated when the aeration system is turned on, and the previous process is repeated, thus forming a circulating airflow. By guiding the full mixing of the water body in the area, the internal microorganisms are enriched at the same time; in the still water river, the impermeable curtain can be opened appropriately to allow the microorganisms to spread and reproduce in large numbers throughout the entire river section, accelerating the degradation of pollutants while improving the biodiversity in the river, improving the river ecological environment, and greatly improving the water purification effect.

[0014] See also Figure 1-2A water purification bed suitable for slightly polluted water bodies comprises an external frame 1, an internal frame 2 arranged inside the external frame 1, and a single-layer flexible mesh cage arranged inside the internal frame 2. The external frame 1 and the upper part of the internal frame 2 are provided with a slide rail and two moving wheels 3, the two moving wheels 3 can move on the slide rail, a watertight curtain 4 is provided between the two moving wheels 3, and the two ends of the watertight curtain 4 are respectively connected to the two moving wheels 3, a plurality of polyurethane filler bodies 5 are provided in the internal frame 2, and an aeration system is provided below the internal frame 2, the aeration system comprises a micro-nano aeration main pipe 6, one or more aeration disc assemblies are provided on the micro-nano aeration main pipe 6, and the aeration disc assembly is connected to the micro-nano aeration main pipe 6 through a first aeration branch pipe 7.
[0015] The aeration plate assembly includes one or more aeration plates 8 .
[0016] The aeration plate assembly includes three aeration plates 8, which are arranged in sequence along the width direction of the internal frame 2. Two adjacent aeration plates 8 are connected by a second aeration branch pipe 9, and any one of the two aeration plates 8 located at the edge is connected to the micro-nano aeration main pipe 6 through the first aeration branch pipe 7.
[0017] The outer frame 1 and the inner frame 2 are both in a rectangular shape.
[0018] The flexible mesh cage outside the external frame 1 completely covers and fits the external frame 1 .
[0019] The total volume of the plurality of polyurethane filler bodies 5 accounts for 70% to 80% of the inner volume of the inner frame 2 .
[0020] The utility model can form a semi-enclosed box structure, and the movable structures of slide rails, moving wheels and impermeable curtains are adopted on all four sides, which can be opened and closed. The internal fixed volume accounts for 70-80% of the polyurethane filler, and an aeration system is installed at the bottom, and the aeration system is supplied with gas by a fan. The aeration system provides a large amount of dissolved oxygen to the inside of the internal frame. In the river channel with frequent water exchange and fast flow rate, the impermeable curtain is completely closed to close the four sides. After the aeration system at the bottom starts aeration, a surrounding airflow will be formed in the cross section of the river channel. After the aeration system is turned on, a discontinuous discontinuous surface is formed between the two fluids of gas and water. Under the interference of the aeration disc, the discontinuous surface loses stability and generates a vortex. The vortex sucks the microorganisms in the purification bed into the jet toward the water surface, and part of the gas escapes from the water surface, and the other part of the gas is mixed with the microorganisms and sinks downward to both sides of the purification bed, and then is sucked into the purification bed again by the negative pressure generated when the aeration system is turned on, and the previous process is repeated, thereby forming a circulating surrounding airflow.
[0021] By guiding the full mixing of water in the area, the internal microorganisms are enriched at the same time; in still water rivers, the impermeable curtains can be opened appropriately to allow microorganisms to spread and multiply in large numbers throughout the entire river section, accelerating the degradation of pollutants while increasing the biodiversity in the river and improving the river's ecological environment.
[0022] The utility model uses modified polyurethane fillers to enhance the adsorption capacity of fillers for pollutants, while also ensuring the amount of microorganisms attached, and uses physical adsorption coupled with microbial treatment to maintain microbial biological activity, thereby maintaining high degradation efficiency; unlike traditional polluted water bodies, water bodies in rivers usually have lower pollution concentrations, and general microbial treatment methods often have poor biological activity and extremely low pollution removal efficiency under low nutrient conditions. In this water purification bed, strains domesticated under low nutrient conditions are used to ensure the activity of microorganisms in slightly polluted water bodies.
