Description

Technical Field

[0001] This invention belongs to the field of environmental protection technology, and in particular relates to a rapid river purification ecological cycle system. Background Technology

[0002] The black and foul-smelling condition of urban rivers is mainly due to excessive pollution, leading to an imbalance between oxygen consumption and demand in the water. Under these conditions, pollutants are transformed into malodorous substances such as ammonia nitrogen, hydrogen sulfide, and volatile organic acids, as well as black substances such as iron and manganese sulfides. Rivers flowing through cities serve the functions of urban sewage and flood discharge. Every day, large amounts of biological wastewater, industrial wastewater, and rainwater mixed with pollutants are discharged into these rivers, causing ecological deterioration and resulting in black and foul-smelling rivers. This negatively impacts the health of urban residents and the urban environment, becoming a persistent and difficult problem to solve in urban environmental protection efforts.

[0003] In existing technologies, methods for treating sewage in rivers include: introducing river sewage into functional bodies such as wetlands or ecological riparian zones through appropriate means; treating polluted water bodies and precipitation / runoff through wetlands, ecological riparian zones, and other purification functional bodies; reducing the organic matter content in the water body and reducing siltation; introducing new water bodies to replenish waterways, lakes, etc.; treating endogenous pollution sources; restoring the nutrient structure of the water body through microbial complexes; and stabilizing or rebuilding the ecosystem and food chain structure.

[0004] Traditional treatment methods have certain drawbacks: First, treating polluted water and runoff through wetlands, ecological riparian zones, and other purification systems requires extensive land use, necessitates designated treatment areas, and involves complex construction, high operational difficulty, and cost. These conditions are not available in some wastewater treatment sections. Second, reducing organic matter and sludge volume in water is difficult to implement and requires multiple chemical treatment methods, resulting in high costs, consumption of large quantities of chemical raw materials, and the use of large machinery. Ultimately, the treatment effect is not ideal and may even cause secondary pollution. Introducing new water into waterways and lakes wastes significant amounts of clean water resources, requires relatively large replenishment volumes, and cannot fundamentally address the pollution source. Treatment methods using microbial composites are time-consuming and have a limited treatment range. While effective for non-flowing wastewater, their effectiveness is minimal for flowing waterways.

[0005] Traditional wastewater treatment equipment and methods suffer from drawbacks such as high cost, limited effectiveness, narrow treatment range, serious resource waste, and strong limitations. Summary of the Invention

[0006] In view of this, the purpose of the present invention is to provide a rapid river purification ecological cycle system to solve the technical problems of high cost and insignificant effect of existing sewage treatment equipment and methods.

[0007] To achieve the above objectives, the technical solution adopted by the present invention for a rapid river purification ecological cycle system is as follows:

[0008] A rapid river purification ecological cycle system includes:

[0009] A filtration structure is set in the upper reaches of the river. The filtration structure includes a support frame fixedly supported on the river, and several filtration units extending into the river water are arranged at intervals on the support frame.

[0010] The filter unit is plate-shaped and its angle relative to the support frame can be adjusted.

[0011] When the river flow is large, the filter unit's plate surface is aligned with the flow direction to allow the river water to drain.

[0012] When the river flow is small, the filter unit's plate surface is perpendicular to the flow direction to filter the river water.

[0013] The filter unit includes a stone filter layer and an activated carbon block layer arranged vertically on the plate surface;

[0014] An ecological floating bed is located downstream of the filter structure. The ecological floating bed includes several detachably connected floating plates. The floating plates have grooves for placing plant pots. The bottom of the grooves has through holes running vertically. Connecting parts are provided at the four corners of the ecological floating bed. Adjacent ecological floating beds are connected by connectors. The floating plates are fixed to the bottom of the river channel by connecting ropes so that the ecological floating bed floats on the river channel.

[0015] The aeration device is located downstream of the ecological floating bed and is laid on the bottom of the river to supply oxygen to the river water.

[0016] Beneficial Effects: This invention provides a rapid river purification ecological cycle system, comprising a filtration structure, an ecological floating bed, and an aeration device. The filtration structure includes a gravel filter layer and an activated carbon block layer, enabling preliminary filtration of river water. The ecological floating bed allows for water purification by planting vegetation that absorbs inorganic substances from the water. The aeration device ensures oxygen supply to the river water. Furthermore, the filtration structure is angle-adjustable. When the river flow is strong, the filter unit's panel is aligned with the river flow direction to facilitate water flow. When the river flow is weak, the filter unit's panel is perpendicular to the river flow direction to filter the water, preventing the filter unit from interfering with the normal flow of the river.

[0017] Furthermore, a bottom plate is provided at the bottom of the river channel, and the bottom of the filter unit is hinged to the bottom plate. Two connecting rods extending vertically are symmetrically fixed above the filter unit. The support frame is provided with guide grooves for the connecting rods to pass through. The two connecting rods extend upward from the guide grooves and are provided with limiting structures so that the filter unit is suspended on the support frame.

[0018] A horizontal bar is fixed to the top of the two connecting rods, and a vertical bar is fixed to the middle of the horizontal bar in its extension direction. The lower end of the vertical bar extends to the support frame and is rotatably set relative to the support frame. A gear is fixed to the upper end of the vertical bar. A rack is provided on the support frame to mesh with the gear. The gear and rack drive each other to realize the angle adjustment of the filter unit.

[0019] Beneficial effects: The meshing of gears and racks allows for easy adjustment of the filter unit's angle, and the structure of the filter unit allows for rotational mounting on the support frame and angle adjustment.

[0020] Furthermore, the guide groove is an arc shape with the vertical rod axis as the center and the distance between the vertical rod and the connecting rod as the radius. Each filter unit corresponds to two guide grooves, and the two guide grooves are symmetrical about the projection center of the vertical rod axis on the horizontal plane.

[0021] Beneficial effects: The guide groove can limit the rotation of the connecting rod, ensuring the stability of the connecting rod during rotation.

[0022] Furthermore, the central angle corresponding to the guide groove is 90°, and each filter unit corresponds to two guide grooves, namely the first guide groove and the second guide groove arranged in front and behind.

[0023] When one connecting rod of the filter unit is located at the rear end of the first guide groove and the other connecting rod is located at the front end of the second guide groove, the plate surface of the filter unit is perpendicular to the flow direction.

[0024] When one connecting rod of the filter unit is located at the front end of the first guide groove and the other connecting rod is located at the rear end of the second guide groove, the plate surface of the filter unit is parallel to the flow direction.

[0025] Beneficial effect: Setting the central angle of the guide groove can ensure that the filter unit is in a state where the plate surface of the filter unit is perpendicular to the flow direction or parallel to the flow direction.

[0026] Furthermore, the filter structure includes a limiting structure that clamps and limits the connecting rod on the support frame. Each filter unit is provided with four sets of limiting structures. The limiting structures clamp the connecting rod at the end of the guide groove so that the filter unit is in a state where the plate surface of the filter unit is perpendicular to the flow direction or parallel to the flow direction.

[0027] Beneficial effects: The limiting structure can keep the filter unit in a state where the plate surface of the filter unit is perpendicular to the flow direction or parallel to the flow direction.

[0028] Furthermore, the limiting structure includes a pair of fixed plates fixedly connected to the support frame, with clamping plates slidably arranged on opposite sides of the fixed plates, and a telescopic structure fixed to the support frame. The clamping plates are fixedly connected to the telescopic structure, and when the clamping plates extend, they clamp and limit the limiting rod.

[0029] Beneficial effects: The limiting structure can clamp the connecting rod and the structure of the limiting structure is reasonably designed.

[0030] The float plate has four elongated holes that run vertically through the grooves around its circumference, and a rope groove is provided between the elongated holes and the edge of the float plate.

[0031] Beneficial effect: The elongated hole facilitates the connection and fixation of the connecting rope.

[0032] Furthermore, the connecting part is a support plate set at the four corners of the float plate. The thickness of the support plate is less than the thickness of the float plate. The support plate has connecting holes. The connecting component includes a circular plate structure with through holes corresponding to the connecting holes of the support plate. The connecting component also includes bolts that pass through the connecting holes and through holes in sequence.

[0033] Beneficial effects: The connection structure is reasonably designed and facilitates fixed connection with the connecting parts.

[0034] The aeration device includes a main pipe and an air distribution pipe laid at the bottom of the river channel, and the main pipe and the air distribution pipe are connected by a connecting pipe.

[0035] Beneficial effects: From the main pipeline to the gas distribution pipe, the gas can be evenly distributed on the bottom of the river.

[0036] Furthermore, the air distribution pipe includes several horizontal pipes spaced apart and vertical pipes connected to the horizontal pipes, the horizontal pipes and vertical pipes forming a horizontal pipe network, and the connecting pipes connected to the vertical pipes.

Detailed Implementation

[0049] The following is a detailed description of a rapid river purification and ecological cycle system according to the present invention, with reference to the accompanying drawings and specific embodiments:

[0050] This invention discloses a rapid river purification ecological cycle system, comprising a filtration structure located upstream of the river, an ecological floating bed located downstream of the filtration structure, and an aeration device located downstream of the ecological floating bed, for purifying river water. The filtration structure includes a support frame 1 fixedly supported on the river, spanning the river surface. Several filtration units 2, extending into the river water, are spaced apart on the support frame 1. Each filtration unit 2 is plate-shaped, comprising a gravel filter layer 31 and an activated carbon block layer 18 arranged perpendicularly to the plate surface. River water enters the gravel filter layer 31, is filtered through it, and then enters the activated carbon block layer 18. The gravel filter layer 31 and the activated carbon block layer 18 further purify the river water. The gravel filter layer 31 filters out flocculent suspended solids and solid pollutants from the river water, while the activated carbon block layer 18 adsorbs particulate suspended pollutants from the river water again.

[0051] In this embodiment, the filter unit 2 can be angled relative to the support frame 1. When the river flow is large, the plate surface of the filter unit 2 is in the same direction as the flow to allow the river water to drain. When the river flow is small, the plate surface of the filter unit 2 is perpendicular to the flow to filter the river water.

[0052] Specifically, a base plate 3 is installed at the bottom of the river channel, perpendicular to the channel. The bottom of the filter unit 2 is hinged to the base plate 3, and the hinge axis between the filter unit 2 and the base plate 3 is located at the middle of the bottom edge of the filter unit 2. Two connecting rods 4 extending vertically are symmetrically fixed above the filter unit 2. A guide groove is provided on the support frame 1 for the connecting rods 4 to pass through. The two connecting rods 4 extend upward from the guide groove, and a limiting structure is provided on the two connecting rods 4 to allow the filter unit 2 to be suspended on the support frame 1. In this embodiment, the limiting structure is a limiting retaining ring 5 provided on the connecting rod 4. Two limiting retaining rings 5 ​​are provided at intervals vertically to stop and limit the filter unit 2 relative to the support frame 1 in the vertical direction.

[0053] A horizontal bar 6 is fixed to the top of the two connecting rods 4. A vertical bar 7 is fixed to the middle of the horizontal bar 6 in its extension direction. The lower end of the vertical bar 7 extends to the support frame 1 and is rotatably set relative to the support frame 1. A gear 8 is fixed to the upper end of the vertical bar 7. A rack 9 that meshes with the gear 8 is provided on the support frame 1. The gear 8 and the rack 9 drive each other to realize the angle adjustment of the filter unit 2. In this embodiment, a drive device is provided at one end of the rack 9 to drive its linear reciprocating movement. The drive device is a hydraulic cylinder. The connection and transmission between the hydraulic cylinder and the rack 9 is existing technology and will not be described in detail here.

[0054] In this embodiment, the guide groove is an arc centered on the axis of the vertical rod 7 and with the distance between the vertical rod 7 and the connecting rod 4 as its radius. The central angle of the guide groove is 90°. Each filter unit 2 corresponds to two guide grooves, which are symmetrical about the projection center of the axis of the vertical rod 7 on the horizontal plane. Each filter unit 2 corresponds to two guide grooves, namely a first guide groove 10 and a second guide groove 11 arranged front and rear. The two connecting rods 4 are located in the first guide groove 10 and the second guide groove 11, respectively, and can be guided to move within the guide grooves. When one connecting rod 4 of the filter unit 2 is located at the rear end of the first guide groove 10 and the other connecting rod 4 is located at the front end of the second guide groove 11, the plate surface of the filter unit 2 is perpendicular to the flow direction; when one connecting rod 4 of the filter unit 2 is located at the front end of the first guide groove 10 and the other connecting rod 4 is located at the rear end of the second guide groove 11, the plate surface of the filter unit 2 is parallel to the flow direction.

[0055] To fix the filter unit 2, in this embodiment, the filter structure includes a positioning structure 12 on the support frame 1 to clamp and limit the connecting rod 4. Each filter unit 2 is provided with four sets of positioning structures 12. The positioning structure 12 clamps the connecting rod 4 at the end of the guide groove so that the filter unit 2 is in a state where the plate surface of the filter unit 2 is perpendicular to the flow direction or parallel to the flow direction. The positioning structure 12 includes a pair of fixing plates 13 fixedly connected to the support frame 1. The fixing plates 13 are spaced apart. A clamping plate 15 is slidably provided on the opposite side of the fixing plates. The support frame 1 is fixed with a telescopic structure. The clamping plate 15 is fixedly connected to the telescopic structure. When the clamping plate 15 extends, it clamps and limits the limiting rod. In this embodiment, a dovetail groove 14 is provided on one side of the fixing plate 13. A slider 16 adapted to the dovetail groove 14 is provided on the side of the clamping plate 15 facing the fixing plate 13. In this embodiment, the telescopic structure is an electric telescopic rod 17. Driven by the electric telescopic rod 17, the telescopic plate can move relative to the fixed plate 13, thereby enabling the telescopic plate to clamp or unlock the connecting rod 4.

[0056] The ecological floating bed includes several detachably connected floating plates 19. The floating plates 19 have a hollow structure to increase their buoyancy. Each floating plate 19 has a groove 20 for placing a plant pot. The bottom of the groove 20 has a through-hole 23, allowing river water to seep into the plant pot through the through-hole 23 for irrigation. Connecting parts are located at the four corners of the ecological floating bed, and adjacent ecological floating beds are connected by connectors. The floating plates 19 are fixed to the bottom of the river channel by connecting ropes to ensure the ecological floating bed floats on the river. Specifically, four elongated holes 21 are evenly distributed around the circumference of the groove 20 on each floating plate 19. Rope grooves 22 are provided between the elongated holes 21 and the edge of the floating plate 19, and the connecting ropes are fixed to the floating plate 19 through the elongated holes 21. In this embodiment, the plants in the plant pots can be *Myriophyllum spicatum* or *Hydrocotyle vulgaris*. Plants utilize their root systems to absorb nutrients from the water, such as total phosphorus, ammonia nitrogen, and organic matter, thereby transferring nutrients from the water body and mitigating eutrophication caused by insufficient self-circulation.

[0057] The connecting parts are support plates 24 located at the four corners of the floats 19. The thickness of the support plates 24 is less than the thickness of the floats 19. The support plates 24 have connecting holes. The connecting components include circular plate structures with through holes 25 corresponding to the connecting holes of the support plates 24. The connecting components also include bolts that pass through the connecting holes and through holes 25 in sequence. Multiple floats 19 are fixedly connected by the circular plate structures and bolts.

[0058] An aeration device is laid at the bottom of the river to oxygenate the river water. The aeration device includes a main pipe 34 and an air distribution pipe 27 laid at the bottom of the river. The main pipe 34 and the air distribution pipe 27 are connected by a connecting pipe 26. In this embodiment, the main pipe 34 is connected to an aerator 32 on the riverbank via a connecting hose 33. The air distribution pipe 27 includes several horizontal pipes 28 spaced apart and vertical pipes 29 connected to the horizontal pipes 28, forming a horizontal pipe network. The connecting pipe 26 connects to the vertical pipes 29, and aeration heads 30 are provided on the horizontal pipes 28. The aerator 32 supplies air to the main pipe 34 via the connecting hose 33, and the main pipe 34 supplies air to the air distribution pipe 27 via the connecting pipe 26.

In this embodiment, the aeration head 30 is arranged at a density of 1 per 50m. 2 Aeration head 30, aeration capacity of 20m³ / h 3 / h. This increases the oxygen content of the river water, facilitating the decomposition of pollutants within the water.

[0059] In this embodiment, microbial agents can be sprayed to assist in regulating water quality according to the pollution status of the river. Bioactive liquids containing photosynthetic bacteria, ammonia-oxidizing bacteria, nitrifying bacteria, and other bacterial groups can be sprayed into the river according to the water quality.

[0060] This invention uses a filtration structure, an ecological floating bed, and an aeration device to sequentially adsorb and filter river water, purify it with green plants, and increase its oxygen content. This effectively removes flocculent suspended solids and solid pollutants from the water, and removes substances such as nitrogen and phosphorus from the water through green plants, thereby achieving long-term and effective purification of river water.
