Description

Technical Field

[0001] The present invention relates to the technical field of water purification, and in particular to an urban river water purification device and process. Background Art

[0002] Water purification is a dynamic process that utilizes a synergistic combination of physical, biological, and chemical methods. With the acceleration of urbanization, urban rivers are facing widespread water quality deterioration. Factors such as the direct discharge of industrial wastewater, domestic sewage, and pollutants carried by rainwater runoff lead to eutrophication, reduced dissolved oxygen, and the accumulation of harmful substances in water bodies, seriously threatening the balance of ecosystems and the health of residents. Efficient, low-energy, intelligent water treatment devices are urgently needed to improve water quality.

[0003] Current mainstream technologies include physical filtration (such as trash racks and aeration equipment), biodegradation (constructed wetlands and microbial agents), and chemical oxidation. For example, patent publication number CN118479649A discloses a device and method for purifying and desilting urban river water, consisting of an aquatic plant cultivation frame and a microbial immobilization bed. The device incorporates a microbial immobilization bed beneath the roots of the aquatic plants and a micro-quantum generator mounted at the bottom, forming a composite purification system. The symbiotic bacteria cultivated in the microbial immobilization bed efficiently decompose pollutants in the water. The micro-quantum generator promotes microbial activity, while the aquatic plants simultaneously absorb nutrients, achieving water purification and ecological restoration. However, the micro-quantum generator in existing purification devices operates at a constant frequency, emitting high-energy particles at a single set frequency to stimulate the water for purification. This frequency can affect the purification effectiveness of water bodies with varying degrees of pollution, sometimes resulting in excessive energy consumption and waste.

[0016] The present application provides another embodiment: urban river water purification art, applied to urban river water purification device, comprising the following implementation steps:

[0017] S1: Aquatic plants that purify water are evenly planted on a cultivation platform near a city river where purification operations are being carried out. After the symbiotic microbial strains that purify the water are transferred to a microbial breeding box, the entire device is placed in the city river. The buoyancy of the water on the cultivation platform suspends it on the water surface, while the aquatic plant roots and the microbial breeding box are immersed below the water surface.

[0018] S2: After the roots of aquatic plants are immersed in river water, they absorb organic matter and corresponding nutrients in the water to carry out photosynthesis to grow, eliminating excess organic matter in the water and collecting suspended black mud particles. At the same time, the anaerobic-aerobic symbiotic bacteria, nitrifying-denitrifying symbiotic bacteria, and phosphate-solubilizing bacteria in the microbial breeding box use their own characteristics to dissolve and transform the enriched organic matter, nitrogen sources, and phosphorus sources in the water.

[0019] S3: River water enters the primary reaction chamber in the shell. The nanobubble generator is activated under the control of the water quality sensing and control module to provide a large number of nanobubbles to the inhaled water to improve the dissolved oxygen in the water. The preliminarily treated water is then introduced into the core reaction chamber through the connecting hole. The high-frequency electrodes in the core reaction chamber are activated under the control of the water quality sensing and control module. When energized, the high-frequency electrodes generate high-energy particles to activate the water, decomposing and oxidizing the organic matter in the water, thereby purifying the water and decomposing the sludge. Finally, the activated water enters the buffer reaction chamber, is adsorbed and purified by the adsorption filler, and is discharged from the water outlet at the bottom of the buffer reaction chamber. This cycle continuously purifies the water in the river.

[0020] S4: The sensors on the side wall of the shell are used to monitor the water quality of the river in real time, and the numerical signals are transmitted to the water quality sensing and control module in a timely manner. The water quality sensing and control module controls the power management module and the frequency conversion module to adjust the frequency of the high-frequency electrode according to the monitoring feedback. Different numbers of purification devices are arranged according to the composition and water quality of the water in the different rivers. According to the different water quality conditions in the river, the high-energy particles produced at different powers after the high-frequency electrode frequency conversion adjustment are used to activate and purify the water.

[0021] Compared with the existing technology, the beneficial effects of the present invention include: the cultivation floating platform is suspended on the water surface by the buoyancy of water, and the roots of aquatic plants planted on its surface penetrate deep into the water, absorbing organic matter and nutrients in the water to promote photosynthesis, thereby realizing the precipitation and collection of black mud particles and the natural reduction of organic matter; the anaerobic-aerobic symbiotic bacteria, nitrifying-denitrifying symbiotic bacteria and phosphate-soluble bacteria loaded in the microbial breeding box are in contact with the water body through permeable micropores to form a biofilm to enhance enzymatic reactions, and the enhanced enzymatic reactions are used to coordinate chemical treatment to improve purification efficiency. The micro-circulation pump built into the shell introduces river water into the primary reaction chamber, and the nanobubble generator releases ultrafine bubbles under the instruction of the water quality sensing and control module, and generates strong oxidizing free radicals through the cavitation effect to decompose pollution. The high-frequency electrodes release energy field quanta under the control of the module, which activate the water body through quantum activation to trigger the decomposition of organic matter and oxidation of sludge, further enhancing the purification effect. Sensors on the side walls of the shell monitor water quality parameters in real time and feed the data back to the water quality perception and control module. The module dynamically adjusts the working power of the high-frequency electrodes through the power management module and the frequency conversion module to adapt it to the organic matter load and water quality characteristics of different water bodies. The entire system can meet the deep treatment needs of highly polluted water bodies by flexibly adjusting the number of devices arranged in the river channel and combining the variable frequency power output of the high-frequency electrodes. It can also reduce energy consumption under conditions of slight differences in water quality and avoid energy redundancy caused by a single power mode. BRIEF DESCRIPTION OF THE DRAWINGS

[0040] In this embodiment, aquatic plants for purifying water bodies are evenly planted on the cultivation floating platform 1 beside the urban river where the purification operation is carried out, and the symbiotic strains of microorganisms for purifying water bodies are transferred to the microorganism breeding box 3. The entire device is placed in the urban river, and the buoyancy generated by water on the cultivation floating platform 1 is used to suspend it on the surface of the water body, so that the roots of the aquatic plants and the microorganism breeding box 3 are immersed below the water surface. After the roots of the aquatic plants are immersed in the river water, they absorb the organic matter and corresponding nutrients in the water body to carry out photosynthesis to grow, thereby eliminating the excess organic matter in the water body and the suspended black mud. The particles are precipitated and collected. At the same time, the anaerobic-aerobic symbiotic bacteria, nitrifying-denitrifying symbiotic bacteria, phosphate-soluble bacteria and other symbiotic bacteria in the microbial breeding box 3 come into contact with the water body through the permeable micropores to form a biofilm to strengthen the enzymatic reaction and coordinate the chemical treatment to improve the overall purification efficiency.

[0041] According to one embodiment of the present invention, Figures 1-2 and Figures 11-12A square planting trough 11 is provided on the top of the cultivation platform 1. Drain holes 12 are evenly spaced on the bottom of the planting trough 11, extending to the bottom of the cultivation platform 1. A leak-proof net 13 is fixedly installed on the inner wall of the planting trough 11 above the leak-proof holes 12. The upper end of the leak-proof net 13 is covered with cultivation soil 14 for planting aquatic plants, including but not limited to reeds, calamus, cattails, water hyacinths, and water lilies. The leak-proof net 13 is used to prevent the cultivation soil 14 from decomposing under the infiltration of river water and leaking out of the drain holes 12. Auxiliary plates 15 are evenly spaced and movable on the inner wall of the planting trough 11.

[0042] The auxiliary plate 15 includes a deflection plate 151 and fixed planting holes 152 evenly spaced at the edges of both ends of the deflection plate 151. The fixed planting holes 152 are semicircular in structure. The adjacent gaps in the vertical state of the deflection plate 151 are used as a path for planting aquatic plants. The gaps in the fixed planting holes 152 are used as the spacing of the planted plants. The side walls of the two ends of the deflection plate 151 are respectively fixedly connected with positioning shafts 153. The positioning shafts 153 are movably connected to the inner wall of the planting trough 11 and the rear end extends through the cavity inside the cultivation floating platform 1. The outer wall of the positioning shaft 153 in the cavity is fixedly connected to the There is an adjusting gear 154, and a limiting rod 155 is provided between the inner walls of the internal cavity of the cultivation floating platform 1. The limiting rod 155 is located below the adjusting gear 154. A transmission chain 156 is movably sleeved on the outer walls of the adjusting gear 154 and the limiting rod 155. The adjusting gear 154 and the limiting rod 155 stretch the transmission chain 156 into a triangle. A pull rod 157 is fixedly connected to one end of the top of the transmission chain 156. The pull rod 157 extends through and extends to the outside of the side wall of the cultivation floating platform 1. The deflection direction of the deflection plate 151 when it automatically returns to a horizontal state is opposite to the manual adjustment direction of the pull rod 157.

[0043] The inner wall at the edge of one end of the deflection plate 151 is evenly spaced with mounting cavities 1511, and the mounting cavities 1511 are distributed between adjacent fixing holes 152. A water inlet hole 1512 is provided at the bottom of the mounting cavity 1511 near one end of the axis of the positioning shaft 153. A hygroscopic expansion cotton 1513 is placed in the mounting cavity 1511 above the water inlet hole 1512. A movable plate 1514 is movably engaged between the inner wall of the mounting cavity 1511 on one side of the hygroscopic expansion cotton 1513.

An elastic component 1515 is fixedly connected between the inner walls of the cavity 1511, and a magnetic block 1516 is fixedly provided on the side wall of the movable plate 1514 between the elastic components 1515. An armature piece 1517 is embedded on the edge side wall corresponding to the magnetic block 1516 at the other end of the deflection plate 151; the deflection plate 151 is suspended in a vertical state at the top port of the planting trough 11, and the armature piece 1517 is located directly below the deflection plate 151. At this time, the magnetic block 1516 and the inner wall of the installation cavity 1511 are in a separated state.

[0044] In this embodiment, after planting aquatic plants in the cultivation soil 14 between the slits of the deflector plate 151, the device is placed in the urban river, and the water force makes the cultivation floating platform 1 suspended on the water surface. The river water flows through the top port of the planting groove 11 and the water-permeable hole 12 at the bottom of the planting groove 11. The developed root system of the aquatic plants can efficiently absorb the nutrients such as nitrogen and phosphorus in the water body, and provide a carrier for the attachment of microorganisms. The aquatic plants inhibit the overgrowth of algae by covering the water surface, absorb heavy metals and organic matter, and increase the dissolved oxygen in the water body through photosynthesis. The aquatic plants form a three-dimensional ecological purification network through the mechanisms of root adsorption, microbial synergistic degradation, and photosynthesis oxygenation, which can effectively reduce the degree of eutrophication of the water body, improve the transparency, restore the self-purification ability of the water ecological system, and the like. After the river water infiltrates the planting groove 11, the water enters the installation cavity 1511 through the water inlet hole 1512 at the side end of the deflector plate 151. Then, the moisture-absorbing and swelling cotton 1513 absorbs sufficient water to make the side of the deflector plate 151 provided with a plurality of installation cavities 1511 heavy. After the moisture-absorbing and swelling cotton 1513 in the installation cavity 1511 absorbs water and swells, the weight of the left and right sides of the deflector plate 151 is balanced, thereby driving the one end of the deflector plate 151 provided with the installation cavity 1511 to automatically deflect downward until the deflector plate 151 is in a horizontal state. After the deflector plate 151 deflects horizontally, the fixed planting hole 152 on the adjacent deflector plate 151 is closed to form a circular hole to enclose the outside of the planted aquatic plant rootstock, thereby limiting the aquatic plant to a certain extent. When the river water infiltrates the port of the planting groove 11, the aquatic plant is prevented from floating up and losing its function due to the shaking. At the same time, the magnetic block 1516 on the side wall of the moving plate 1514 in the installation cavity 1511 of the deflector plate 151 attracts the armature plate 1517 on the side wall of the adjacent deflector plate 151, so that all the deflector plates 151 are sequentially and horizontally attached to cover the top port of the planting groove 11, thereby preventing the cultivation soil 14 in the planting groove 11 from escaping and losing due to the splashing of the river water. When the plants need to be replaced, the pull rod 157 is pulled outward of the cultivation floating platform 1. The pull rod 157 cooperates with the transmission chain 156 and the adjusting gear 154 to drive the deflector plate 151 to rotate clockwise to the vertical state. The magnetic block 1516 in the installation cavity 1511 loses the attraction force and is pushed downward under the action of its own gravity to squeeze the moisture-absorbing and swelling cotton 1513, so that the absorbed river water is automatically squeezed out. The deflector plate 151 is kept in the vertical state. After the planting and replacement are completed, the deflector plate 151 is automatically reset again according to the above operation, and the pull rod 157 is reset in the reverse direction. The use is convenient.

[0045] According to an embodiment of the present application Figures 1-2 and Figures 6-10As shown. Mounting platforms 16 are evenly spaced at the top edge of the cultivation floating platform 1 outside the planting trough 11. The bottom plate of the mounting platform 16 is set at a height lower than the bottom plate of the planting trough 11, and an auxiliary floating plate 5 is movably set between the side walls of the mounting platform 16.

The first light floating plate 51 and the second light floating plate 52 are alternately spaced and hinged end to end. An inner groove 53 is provided on the side wall of the end of the mounting platform 16 farthest from the mounting platform 16. A positioning rod 54 is fixedly connected between the side walls of the inner groove 53. A collar 55 is movably sleeved on the outer wall of the positioning rod 54. The bottom of the collar 55 is movably connected to a telescopic link. Rod 56, a storage groove 17 is provided on the bottom plate of the mounting platform 16 corresponding to the telescopic connecting rod 56, and the end of the telescopic connecting rod 56 is fixedly connected to the inner wall of the storage groove 17, and guide grooves 57 are respectively provided on the side walls at both ends of the first lightweight floating plate 51 movably connected to the inner wall of the mounting platform 16, and an adjusting member 6 is movably connected in the guide groove 57. The bottom of the contact end of the adjacent first lightweight floating plate 51 and the second lightweight floating plate 52 is provided with a strip hole 58, and an elastic rod 59 is fixedly connected between the inner walls of the strip hole 58. One end of the elastic rod 59 is fixed in the strip hole 58 at the bottom of the first lightweight floating plate 51, and the other end is fixed in the strip hole 58 at the bottom of the second lightweight floating plate 52. After the first lightweight floating plate 51 and the second lightweight floating plate 52 are fitted together, the elastic rod 59 is bent in a U shape.

[0046] The adjusting member 6 includes an adjusting gear box 61 fixed in the internal cavity of the cultivation platform 1, and a moving rod 62 is provided between the upper and lower end surfaces of the adjusting gear box 61, and the lower end of the moving rod 62 extends to the bottom of the bottom plate of the cultivation platform 1, and the bottom of the moving rod 62 is fixedly connected to the adjusting floating plate 63, and the bottom of the adjusting floating plate 63 is fixedly connected to the auxiliary cover 64. A tooth groove 621 is provided on the side wall of the moving rod 62, and a gear group 611 meshing with the tooth groove 621 is provided inside the adjusting gear box 61, and a transmission rod 65 is fixedly provided on the gear side wall at the tail end of the gear group 611. Both ends of the transmission rod 65 extend to the outside of the adjusting gear box 61, and the end of the transmission rod 65 is fixedly connected to an L-shaped connecting rod 66, and the end of the L-shaped connecting rod 66 is movably engaged in the guide groove 57 on the side wall of the first lightweight floating plate 51.

[0047] In this embodiment, when the cultivation floating platform 1 is suspended on the surface of the river, the adjusting floating plate 63 and the auxiliary cover 64 at the lower end of the moving rod 62 are immersed in the water body and move downward with the sinking of the device. After the device stops sinking, the adjusting floating plate 63 and the auxiliary cover 64 are driven by the water buoyancy to move upward, the gear set 611 in the adjusting gear box 61 is rotated by the tooth groove 621 of the moving rod 62, the transmission rod 65 is rotated clockwise by the meshing of the automatic multiple gears of the gear set 611, the L-shaped connecting rod 66 at both ends is deflected clockwise when the transmission rod 65 rotates clockwise, and the cultivation tank 11 and the installation platform 16 inside the cultivation floating platform 1 exist a cavity, so that the end of the L-shaped connecting rod 66 is deflected outward clockwise from the through groove on the side wall of the cavity, and the end shaft of the L-shaped connecting rod 66 slides downward in the guide groove 57 on the side wall of the first light floating plate 51 after deflection, so that the top of the first light floating plate 51 is deflected and tilted downward. At this time, the elastic rod 59 is squeezed and bent in the elastic state and is released, and when the top of the first light floating plate 51 is deflected and tilted downward, the elastic rod 59 pushes the bottom of the second light floating plate 52 to slide outward of the cultivation floating platform 1, so that the first light floating plate 51 and the second light floating plate 52 are unfolded and stretched to the horizontal in turn. When the first light floating plate 51 and the second light floating plate 52 are deflected and stretched to the horizontal, the telescopic connecting rod 56 is stretched synchronously, and the end of the second light floating plate 52 is tensioned by the sleeve ring 55 after the telescopic connecting rod 56 is stretched, so that the first light floating plate 51 and the second light floating plate 52 inside the installation platform 16 on the side wall of the cultivation floating platform 1 are automatically laid and suspended on the water surface. The suspension of the first light floating plate 51 and the second light floating plate 52 increases the contact area with the water, thereby ensuring the stability of the device suspended on the water surface, avoiding the device from capsizing caused by the violent shaking of the river water in strong wind, and ensuring the use stability of the device. After the device is taken out of the water, the first light floating plate 51 and the second light floating plate 52 are automatically folded by pressing the moving rod 62 downward, so as to avoid the device from occupying too much space and be convenient and practical.

[0048] In order to better show the urban river water purification device, the present embodiment provides an urban river water purification method, which is applied to the urban river water purification device and includes the following implementation steps:

[0049] Step one: evenly plant the aquatic plants for purifying water on the cultivation floating platform 1 on the side of the urban river where the purification operation is implemented, and transfer the symbiotic microorganism species for purifying water into the microorganism breeding box 3, then put the device as a whole into the urban river, use the water to generate the buoyancy of the cultivation floating platform 1 to make it suspended on the surface of the water body, and make the root system of the aquatic plants and the microorganism breeding box 3 immersed below the water surface;

[0050] Step 2: After the roots of aquatic plants are immersed in river water, they absorb organic matter and corresponding nutrients in the water body to carry out photosynthesis to grow, eliminating excess organic matter in the water body while precipitating and collecting suspended black mud particles. At the same time, the anaerobic-aerobic symbiotic bacteria, nitrifying-denitrifying symbiotic bacteria, and phosphate-solubilizing bacteria in the microbial breeding box 3 use their own characteristics to dissolve and transform the enriched organic matter, nitrogen source, and phosphorus source in the water body;

[0051] Step 3: River water enters the primary reaction chamber 431 in the shell 43. The nanobubble generator 432 is activated under the control of the water quality sensing and control module 423 to provide a large number of nanobubbles to the inhaled water to improve the dissolved oxygen in the water. The preliminarily treated water is then introduced into the core reaction chamber 433 through the connecting hole 434. The high-frequency electrode 435 in the core reaction chamber 433 is activated under the control of the water quality sensing and control module 423. When energized, the high-frequency electrode 435 generates high-energy particles to activate the water, decomposing and oxidizing organic matter in the water, thereby purifying the water and decomposing sludge. Finally, the activated water enters the buffer reaction chamber 436, undergoes adsorption purification treatment by the adsorption filler 437, and is then discharged from the water outlet at the bottom of the buffer reaction chamber 436. This cycle continues to continuously purify the river water.

[0052] Step 4: Use the sensor 44 on the side wall of the shell 43 to monitor the water quality of the river in real time, and transmit the numerical signal to the water quality sensing and control module 423 in time. The water quality sensing and control module 423 controls the power management module 422 and the frequency conversion module 424 to perform frequency conversion adjustment on the power used by the high-frequency electrode 435 based on the monitoring feedback. Different numbers of purification devices are arranged according to the composition and water quality of the water in different rivers. According to the different water quality conditions of the river, the high-energy particles produced at different powers after the frequency conversion adjustment of the high-frequency electrode 435 are activated and purified.
