Description

Technical Field

[0001] The invention relates to the technical field of river channel cleaning, in particular to a river channel pollution ecological control device. Background Art

[0002] River ecological restoration refers to the use of ecosystem principles and various methods to repair the biological communities and structures of damaged water ecosystems, rebuild healthy aquatic ecosystems, repair and strengthen the main functions of water ecosystems, and enable the ecosystem to achieve a virtuous cycle of overall coordination, self-sustaining and self-succession.

[0003] Common ecological restoration technologies include phytoremediation, which utilizes plants' ability to absorb, transform, and degrade pollutants in water to purify water quality. By planting suitable plants in polluted waters, their biosorption, biodegradation, and biotransformation mechanisms effectively remove harmful substances from the water. Furthermore, plant root secretions promote the growth of phosphate- and nitrogen-loving bacteria, indirectly improving pollutant degradation efficiency.

[0004] However, the above method has the following defects: 1. The plant restoration cycle is long, and regular harvesting is required to achieve complete removal of pollutants. It is difficult to see quick results when used alone; 2. Affected by environmental factors, the plant restoration effect is affected by environmental conditions such as temperature, light, and water quality, and the efficiency decreases in winter or when the pollution load is too high; 3. The treatment effect is single, only removing nutrients such as nitrogen and phosphorus, and the effect of removing organic pollutants in wastewater is general; 4. The maintenance and management are complicated and long-term maintenance (such as harvesting and replanting) is required, otherwise dead plants may cause secondary pollution.

[0036] The present invention will now be described in further detail with reference to the accompanying drawings, which are simplified schematic diagrams that illustrate the basic structure of the present invention in a schematic manner.

[0037] Example 1:

[0038] like Figure 1 and Figure 2 As shown, the present invention discloses a river pollution ecological control device, which includes a box body 1 and a transparent glass chamber 10 installed on the top of the box body 1.

[0039] The box body 1 is made of plastic plates spliced into a rectangular parallelepiped with the opening facing upwards. Figure 5 and Figure 9 As shown, vertically arranged sieve plates 2 are respectively provided near the left and right sides of the interior, dividing the box body 1 into a connected water inlet chamber 3, a purification chamber 4 and a water outlet chamber 5.

[0040] The housing 1 is also equipped with multiple perforated electrode sheets 7. These are positioned within the purification chamber 4 and parallel to the sieve plate 2, dividing the purification chamber 4 into multiple carbon cavities 9 filled with activated carbon 8. The electrode sheets 7 are arranged in alternating positive and negative configurations, with the positive electrode sheets 7 connected to the positive terminal of a power source, and the negative electrode sheets 7 connected to the negative terminal of the power source. The pore size of the sieve plate 2 is smaller than the particle size of the activated carbon 8. In this embodiment, the electrode sheets 7 are titanium substrates loaded with an antiperovskite phase of Co4N. The spacing between the electrode sheets 7 is 5-10 cm, and the voltage of the power source connected to the electrode sheets 7 is 30-50V. This converts nitrate pollutants in wastewater into ammonia that can be used by plants.

[0041] A water pump 6 is mounted on the outer wall of the housing 1. Its outlet is connected to the water inlet chamber 3 via a pipe. This pump draws water from the river into the inlet chamber 3. The water then passes through the purification chamber 4 and the outlet chamber 5, and flows into the river through the outlet pipe of the outlet chamber 5. A check valve 24 is mounted on the outlet pipe to prevent water from entering the outlet chamber 5 through the outlet pipe.

[0042] like Figure 8 As shown, the upper end of the box body 1 is covered with a cover plate 26, and the upper end of the electrode sheet 7 is provided with an upwardly protruding protrusion, which passes upward through the slot 27 on the cover plate 26 and is connected to the power supply.

[0043] The glass chamber 10 is constructed of plexiglass, with an open lower end fixed to the upper end of a cover plate 26. Multiple plants 11 are planted within the glass chamber 10. In this embodiment, plants 11 are lucky bamboo. The cover plate 26 is provided with rows of planting holes 28, each row of planting holes 28 directly below a carbon chamber 9. The lower end of the lucky bamboo plant passes through the planting holes 28, with its roots located within the carbon chamber 9 and plugged into the activated carbon 8.

[0044] The top of the glass chamber 10 is a pointed structure, comprising two V-shaped mounting plates 14 and a breathable plate 16. A solar photovoltaic panel 15 is mounted on the outer side of the mounting plate 14, and a light source 12 is mounted on the inner side, emitting red and blue light downwards with wavelengths of 660nm and 450nm respectively.

[0045] like Figure 4-7As shown, the air permeable plate 16 is provided with a plurality of evenly distributed air holes 17, which connect the outside world with the inner cavity of the glass chamber 10. The inner side wall of the air permeable plate 16 is provided with two symmetrically arranged guide bars 25 with L-shaped end faces. The guide bars 25 and the air permeable plate 16 form a guide groove 19 with opposing openings, and the sealing plate 18 is inserted into the guide groove 19. The inner side wall of the air permeable plate 16 is also installed with an electric cylinder 20, whose driving end is connected to the sealing plate 18 and is used to drive the sealing plate 18 to move back and forth, so that the sealing plate 18 can block the air permeable holes 17 or move the sealing plate 18 away from the air permeable holes 17. The arrangement of the sealing plate 18 and the electric cylinder 20 installed on the inner side of the air permeable plate 16 allows the air permeable plate 16 to protect the electric cylinder 20.

[0046] The electricity generated by the solar photovoltaic panel 15 is used for the light source 12, the water pump 6, the electric cylinder 20 and the power supply for the electrode sheet 7. In this embodiment, a battery can be installed on the upper end of the cover plate 26 to store excess electricity and power the above devices at night or on cloudy days.

[0047] The sealing plate 18 is provided with multiple through-holes 21 corresponding to the air holes 17. When the sealing plate 18 moves, the through-holes 21 can be connected to or completely offset from the air holes 17. This arrangement shortens the movement distance of the sealing plate 18 and the stroke of the electric cylinder 20, thus minimizing the space occupied by the electric cylinder 20 within the air permeable plate 16 and reducing costs.

[0048] Normally, sealing plate 18 blocks vent 17. When the temperature rises above 30°C, sealing plate 18 is driven to move, allowing through-hole 21 and vent 17 to coaxially connect, connecting the interior of glass chamber 10 to the outside world and achieving a cooling effect. In this embodiment, a temperature sensor can also be installed in glass chamber 10 to automatically control the operation of electric cylinder 20.

[0049] The outer side of the box body 1 is also equipped with a floating block 13, and its buoyancy configuration is such that the activated carbon 8 is located below the liquid level, while the branches and leaves of the lucky bamboo are above the liquid level. In this way, the utilization rate of the activated carbon 8 can be improved.

[0050] The specific installation structure of the float 13 is as follows: Figure 3 As shown, T-shaped blocks 22 are installed on opposite sides of the housing 1. The floating blocks 13 are provided with T-shaped slots 23 that engage the T-shaped blocks 22. This not only facilitates the installation of the floating blocks 13 but also improves the stability of the mounting structure. Multiple floating blocks 13 are provided, and the buoyancy can be adjusted by increasing or decreasing the number of floating blocks 13.

[0051] When the device is installed in a river, the opposite ends of the box 1 are anchored, and the solar photovoltaic panel 15 faces south. The number of floating blocks 13 is adjusted so that the activated carbon 8 is below the liquid level and the branches and leaves of the lucky bamboo are above the liquid level.

[0052] The present invention operates as follows: When the water pump 6 is operating, it draws water from the river into the water inlet chamber 3. The water is filtered by the left sieve plate 2 and then alternately passes through the carbon chamber 9 and the electrode plate 7. After purification and decomposition, the water enters the water outlet chamber 5. Finally, under the action of water pressure, the check valve 24 opens and the water flows back into the river, thereby purifying the river water. As the river water flows into the purification chamber 4, pollutants are adsorbed by the activated carbon 8. Phosphorus and ammonia nitrogen are absorbed by plant roots. Nitrate ions are converted into plant-usable ammonia by the electrode plate 7. Organic matter decomposes under the action of the electrode plate 7, producing carbon dioxide, which rises to the glass chamber 10 above and is absorbed and utilized by the lucky bamboo. Stimulated by the electrode plate 7, the lucky bamboo grows faster, achieving excellent pollutant removal results. As the lucky bamboo grows taller, the upper section can be cut off and planted elsewhere, allowing the lower section and roots to continue growing. This ensures a continuous year-round removal of nutrients and organic pollutants from the river.

[0053] Therefore, the advantages of this embodiment are as follows: 1. This device enriches plants with nutrients by first enriching them and then supplying them for plant growth. The voltage applied to the electrode 7 promotes rapid plant growth, and the blue and red lights stimulate plant photosynthesis, leading to the rapid growth of lucky bamboo. 2. The greenhouse space created by this device can regulate the temperature of plant growth, ensuring that plants have a suitable temperature year-round, avoiding the disadvantage of being unable to repair the environment in winter. 3. This device not only removes nitrogen and phosphorus substances but also degrades organic matter, with the resulting carbon dioxide being used to promote plant growth. 4. This device enhances plant growth. Through the adsorption and enrichment of activated carbon 8, nutrients required for plant growth are concentrated around the root system, promoting rapid plant growth. 5. The root electrode 7 of this device promotes plant growth while simultaneously degrading organic matter adsorbed by the activated carbon 8, converting it into carbon dioxide, which naturally rises into the greenhouse to be used by the plants for growth. 6. The blue and red lights provided within this device not only extend the plant's daylight hours but also accelerate plant growth and the conversion of root nutrients into biomass. 7. When using lucky bamboo for water restoration, you can harvest directly from the top without damaging the root system and can continuously remove nutrients from the water.

[0054] Example 2:

[0055] Compared with the first embodiment, the difference is: Figure 10 As shown, the buoyancy blocks 13 are provided as two symmetrically arranged blocks, and the buoyancy is adjusted by cutting and reducing the weight.
