Abstract
Description
Technical Field
[0001] This invention belongs to the field of water treatment technology, specifically a modular device and method for the coordinated treatment of black and odorous water in rivers and ecological restoration. Background Technology
[0002] With the acceleration of urbanization and the increase in industrial and domestic sewage discharge, some rivers have accumulated pollutants (COD, ammonia nitrogen, total phosphorus, organic pollutants, etc.) exceeding the standards, forming black and odorous water bodies. This not only disrupts the water ecological balance but also affects the living environment of surrounding residents and the urban landscape. Traditional technologies often focus on "removal of single pollutants" (such as using only aeration to increase oxygen and remove odors, or chemical agents to flocculate and remove phosphorus), lacking a synergistic design of "pollution control and ecological restoration". This leads to a rebound in water quality after short-term compliance (such as algal blooms and recurrence of black and smelly conditions). Furthermore, some chemical treatment technologies require continuous addition of chemicals, which can easily cause secondary pollution and high operation and maintenance costs. Summary of the Invention
[0003] To address the problems mentioned in the background section, this invention provides a modular device and method for the coordinated treatment of black and odorous water in rivers and ecological restoration.
[0004] To achieve the above objectives, the present invention provides the following technical solution: a modular synergistic treatment device for black and odorous river water treatment and ecological restoration, comprising a purification cylinder, wherein a filter cylinder one and a filter cylinder two for adsorption, filtration, and purification are attached to the inner wall of the purification cylinder. The filter cylinder one is filled with a mixed filler of activated carbon and zeolite, and the filter cylinder two is filled with a modified ceramsite carrier. The filter cylinder one and the filter cylinder two are also attached to each other, and a disc is attached to the bottom end of the filter cylinder one. A cylindrical plate is attached to the outer wall at the bottom and fixedly connected to the inner wall at the bottom of the purification cylinder. The connection between the cylindrical plate and the cylindrical plate is used to divide the lower inner wall of the purification cylinder into a medicine placement chamber for placing baking soda powder. A frame mesh plate is provided on the side of the purification cylinder. The frame of the frame mesh plate is used for planting aquatic plants in sections. Several biological rope fillers are attached and suspended on the bottom frame of the frame mesh plate. A flange is fixedly connected to one end of both the purification cylinder and the frame mesh plate. An assembly part is provided between the purification cylinder and the frame mesh plate.
[0005] Preferably, a large plate is fixedly connected to the inner wall of the bottom end of the purification cylinder, and a motor is fixedly connected to the outer wall of the center top of the large plate. The motor shaft and the plate body of the large plate are rotatably connected through the motor shaft, and a pH sensor is also fixedly connected to the bottom end of the motor shaft.
[0006] Preferably, a small plate is fixedly connected to the shaft of the motor, and a shield is fixedly connected to the top side wall of multiple plates on the small plate. The top outer wall of each shield is slidably connected to the bottom outer wall of the purification cylinder, and an L-shaped arc plate is fixedly connected to the top of multiple plates on the small plate.
[0007] Preferably, an annular groove is provided at one bottom end of the purification cylinder, and the L-shaped arc plate and the inner wall of the annular groove are slidably connected. Multiple cylinder grooves are provided through the bottom cylinder body of the purification cylinder, and a hopper is fixedly connected to the inner wall of the top of each cylinder groove.
[0008] Preferably, two material trays are fixedly connected to the inner wall of the cylindrical groove, and a discharge hole is opened through the side wall of each of the two material trays. The two material trays are fixedly connected to the inner wall of the cylindrical groove and are rotatably connected to it. A rotating shaft is rotatably connected through the upper material tray. The rotating shaft is fixedly connected through the tray body of the lower material tray. A cylindrical cover is fixedly connected to the upper half of the rotating shaft. The cylindrical cover is rotatably connected to the top tray body of the upper material tray.
[0009] Preferably, a torsion spring is fixedly connected between the rotating shaft and the material tray, the L-shaped arc plate is a hard rubber plate and its plate body is intermittently attached to the plate body of the material tray below, and a stirrer is fixedly connected to the bottom of multiple plates of the small plate.
[0010] Preferably, the assembly part includes a vertical plate, and a telescopic electric cylinder is fixedly connected to the plate body. The telescopic electric cylinder is provided with a meshing component, which is composed of a toothed plate and a gear meshing with it. The top end of the toothed plate is fixedly connected to the movable end of the telescopic electric cylinder.
[0011] Preferably, two protective covers are fixedly connected to the plate body of the upright plate. The two protective covers are respectively slidably connected to the movable end of the telescopic electric cylinder and the plate body of the gear plate. A bidirectional threaded rod is fixedly connected to the gear, and the rod body of the bidirectional threaded rod is movably sleeved with the protective cover below.
[0012] Preferably, both sides of the bidirectional threaded rod are threaded with sleeve plates, the two sleeve plates are slidably connected to a support column, and one end of each of the two sleeve plates is fixedly connected with a snap-fit shaft plate. The shafts on the two snap-fit shaft plates can be slidably snapped into the two flanges, and the two snap-fit shaft plates are also slidably connected to the support column. An anchor rod is threadedly connected to the bottom column of the support column.
[0013] The modular approach to the coordinated treatment of black and odorous water in rivers and the steps for its operation and use are as follows: Step 1: The river water passively passes through the first filter cylinder, where the mixed packing material of activated carbon and zeolite adsorbs and filters residual organic matter and heavy metal ions. When it passes through the second filter cylinder, the modified ceramic carrier loaded with composite microbial flora can degrade pollutants such as COD, ammonia nitrogen, and total phosphorus, achieving a double-layer adsorption and purification effect. Step 2: At the same time, aquatic plants such as calamus, canna lily, and foxtail algae are planted in sections within the frame mesh panel. These plants have well-developed root systems and are resistant to pollution. The plant roots form a "biofilm" that further adsorbs and degrades pollutants, while providing a habitat for microorganisms. In addition, bio-rope fillers are suspended at the bottom of the frame mesh panel, which can enhance the attachment of microorganisms. Step 3: Before placing the purification cylinder and frame mesh, insert the support column into the two flanges. Then, manually activate the telescopic electric cylinder on the upright plate to move the toothed plate in the meshing assembly downwards, and the meshing drive gear rotates. This drives the bidirectional threaded rod to rotate. The rotation of the bidirectional threaded rod drives the sleeve plate on the rod body to guide and translate the clamping shaft plate on the support column until multiple shafts on the clamping shaft plate are slidably clamped into the flanges, and the two are quickly assembled and connected.
[0014] Compared with the prior art, the beneficial effects of the present invention are as follows: This invention uses a mixture of activated carbon and zeolite in the first filter cylinder to purify river water, adsorbing and filtering residual organic matter and heavy metal ions. When the water passes through the second filter cylinder, a modified ceramic granule carrier loaded with composite microbial flora is placed there, which can degrade pollutants such as COD, ammonia nitrogen, and total phosphorus, achieving a double-layer adsorption and purification effect. This invention utilizes aquatic plants such as calamus, canna lily, and foxtail grass, which are planted in sections within a frame mesh panel. These plants have well-developed root systems and are resistant to pollution. The plant roots form a "biofilm" that further adsorbs and degrades pollutants, while providing a habitat for microorganisms. Furthermore, the bio-rope filler suspended at the bottom of the frame mesh panel enhances microbial attachment. Additionally, by installing solar panels and micro-aeration pumps on both sides of the frame mesh panel 117, which are common in the prior art, dissolved oxygen is replenished to the water, ensuring the survival of aquatic plants and microorganisms. This invention involves inserting the connecting column into two flanges, then manually activating the telescopic electric cylinder on the upright plate to move the toothed plate in the meshing assembly downwards, causing the meshing drive gear to rotate. This rotation drives the bidirectional threaded rod to rotate, which in turn drives the sleeve plate on the rod body to guide and translate the clamping shaft plate on the connecting column until multiple shafts on the clamping shaft plate are slidably clamped into the flanges, thus enabling the rapid assembly and connection of the purification cylinder and frame mesh plate as a whole.

[0017] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0018] like Figures 1 to 8As shown, this invention provides a modular synergistic treatment device for treating black and odorous water in rivers and restoring the ecosystem. It includes a purification cylinder 1. Two filter cylinders, a first filter cylinder 101 and a second filter cylinder 102, are attached to the inner wall of the purification cylinder 1 for adsorption, filtration, and purification. The first filter cylinder 101 is filled with a mixed filler of activated carbon and zeolite, while the second filter cylinder 102 is filled with a modified ceramsite carrier. The first filter cylinder 101 and the second filter cylinder 102 are also attached to each other. A cylinder disc 103 is attached to the bottom end of the first filter cylinder 101, and a cylinder disc 103 is attached to the outer wall of the bottom end of the cylinder disc 103. A cylindrical plate 104 is fixedly connected to the inner wall of the bottom end of the purification cylinder 1. The connection between the cylindrical plate 103 and the cylindrical plate 104 is used to divide the lower half of the inner wall of the purification cylinder 1 into a medicine placement chamber for placing baking soda powder. A frame mesh plate 117 is provided on the side of the purification cylinder 1. The frame of the frame mesh plate 117 is used for planting aquatic plants in sections. Several biological rope fillers 118 are attached and suspended on the bottom frame of the frame mesh plate 117. A flange 119 is fixedly connected to one end of the purification cylinder 1 and the frame mesh plate 117. An assembly part 2 is provided between the purification cylinder 1 and the frame mesh plate 117.
[0019] The above solution involves installing a water pump at the top of the purification cylinder 1 to pump river water through it. The two ends of the purification cylinder 1 are the inlet and outlet, respectively, and the inner wall of the cylinder is coated with an anti-corrosion coating. Figure 3 As shown, the river water passively passing through the filter cylinder 101 will be purified by the adsorption of residual organic matter and heavy metal ions in the filtered water by the mixed packing material of activated carbon and zeolite (mass ratio 1:2). When passing through the filter cylinder 102, the modified ceramic granules placed there will carry a complex microbial community (Bacillus subtilis, nitrifying bacteria, denitrifying bacteria, etc.), which can degrade pollutants such as COD, ammonia nitrogen, and total phosphorus, achieving the effect of microbial purification. At the same time, the aquatic plants planted in the frame mesh plate 117, such as calamus, canna, and foxtail algae, have well-developed root systems and are resistant to pollution. The plant roots form a "biofilm" to further adsorb and degrade pollutants, while providing a habitat for microorganisms. The bio-rope packing material 118 suspended at the bottom of the frame mesh plate 117 can enhance the attachment of microorganisms. In addition, by setting up solar panels and micro aeration pumps on both sides of the frame mesh plate 117, dissolved oxygen is added to the water, ensuring the survival of aquatic plants and microorganisms.
[0020] A large plate 105 is fixedly connected to the inner wall of the bottom end of the purification cylinder 1. A motor 106 is fixedly connected to the outer wall of the top center of the large plate 105. The shaft of the motor 106 is rotatably connected to the plate body of the large plate 105. A pH sensor 107 is also fixedly connected to the bottom end of the shaft. A small plate 108 is also fixedly connected to the shaft of the motor 106. A shield 109 is fixedly connected to the top side wall of multiple plates on the small plate 108. The top outer wall of each shield 109 is slidably connected to the bottom outer wall of the purification cylinder 1. An L-shaped arc plate 110 is fixedly connected to the top of multiple plates on the small plate 108. An annular groove is opened at one bottom end of the purification cylinder 1. The L-shaped arc plate 110 is slidably connected to the inner wall of the annular groove. Multiple cylindrical grooves are opened through the bottom cylinder body of the purification cylinder 1. A hopper 111 is fixedly connected to the inner wall of the top of each cylindrical groove.
[0021] The above solution is adopted: such as Figure 4 and Figure 5 As shown, the pH sensor 107 installed on the motor 106 monitors the pH value of the water in real time. When the river water exceeds the pH range, the motor 106 will be started directly to drive the small plate 108 to rotate. The rotating small plate 108 will directly drive the multiple shields 109 and L-shaped arc plates 110 installed on the plates to rotate together. The passively rotating shields 109 and L-shaped arc plates 110 will always be in close contact with the bottom of the purification cylinder 1 and the inner wall of the annular groove it opens.
[0022] Two material trays 112 are fixedly connected to the inner wall of the cylindrical trough. Each of the two material trays 112 has a through-hole 113 on its side wall. The two material trays 112 are fixedly connected to the inner wall of the cylindrical trough and are rotatably connected to it. A rotating shaft 114 is rotatably connected to the upper material tray 112. The rotating shaft 114 is fixedly connected to the disc body of the lower material tray 112. A cylindrical cover is fixedly connected to the upper half of the rotating shaft 114. The cylindrical cover is rotatably connected to the top disc body of the upper material tray 112. A torsion spring 115 is fixedly connected between the rotating shaft 114 and the material tray 112. The curved plate of the L-shaped arc plate 110 is a hard rubber plate and its plate body is intermittently connected to the plate body of the lower material tray 112. A stirrer 116 is fixedly connected to the bottom of multiple plates of the small plate 108.
[0023] The above solution is adopted: such as Figure 6As shown, the continuously passively rotating L-shaped arc plate 110 intermittently contacts the lower material tray 112. Through friction, the lower material tray 112 rotates, intermittently aligning the discharge holes 113 on the plate with those on the upper material tray 112. Once aligned, the baking soda powder discharged from the hopper 111 is discharged naturally onto the shielding plate 109. When the lower material tray 112 rotates under force, it also synchronously drives the rotating shaft 114 to rotate. This directly drives the torsion spring 115 mounted on the rotating shaft 114 and the upper material tray 112 to rotate and deform, thereby allowing the L-shaped arc plate to rotate. When 110 and the lower feeding tray 112 are not in contact, the lower feeding tray 112 is automatically reset, allowing for the addition of small amounts of baking soda each time. After the lower feeding tray 112 is passively reset, the cover plate 109 will also rotate out of the opening position of the cylinder groove. The bottom of the cylinder groove can scrape the baking soda placed on the outer wall of the top of the cover plate 109, dissolving it in the river water, ensuring the activity of microorganisms and the adaptability to subsequent ecological restoration. The small plate 108 in the passively rotating state will simultaneously drive the stirrer 116 to rotate and stir the baking soda and water, accelerating the mixing between the two. Then, the water is adsorbed and purified by the filter cylinder 101 and the filter cylinder 102.
[0024] The assembly section 2 includes a vertical plate 201. A telescopic electric cylinder 202 is fixedly connected to the plate body of the vertical plate 201. The telescopic electric cylinder 202 is equipped with a meshing component 203, which consists of a toothed plate and a gear meshing with it. The top end of the toothed plate is fixedly connected to the movable end of the telescopic electric cylinder 202. Two protective covers 205 are also fixedly connected to the plate body of the vertical plate 201. The two protective covers 205 are respectively slidably connected to the movable end of the telescopic electric cylinder 202 and the plate body of the toothed plate. A bidirectional threaded rod 204 is fixedly connected through the gear. The rod body of the threaded rod 204 and the lower protective cover 205 are movably connected. Both sides of the rod body of the bidirectional threaded rod 204 are threaded with sleeve plates 206. The two sleeve plates 206 are slidably connected to the support column 208. Each of the two sleeve plates 206 is also fixedly connected to a snap-fit shaft plate 207. The shafts on the two snap-fit shaft plates 207 can be slidably snapped with the two flanges 119. The two snap-fit shaft plates 207 are also slidably connected to the support column 208. An anchor rod 209 is threadedly connected to the bottom column of the support column 208.
[0025] Using the above method: Before placing the purification cylinder 1 and the frame mesh panel 117, such as Figure 7 and Figure 8As shown, the connecting column 208 can be inserted into the two flanges 119 by inserting it. Then, the telescopic electric cylinder 202 on the upright plate 201 is manually activated to drive the toothed plate in the meshing assembly 203 to move down, meshing the drive gear to rotate. This drives the bidirectional threaded rod 204 to rotate. The rotation of the bidirectional threaded rod 204 drives the sleeve plate 206 on the rod body to guide the clamping shaft plate 207 to move horizontally on the connecting column 208 until the multiple shafts on the clamping shaft plate 207 are slidably clamped into the flanges 119, allowing for quick assembly and connection. The anchor rod 209 is used to firmly anchor it into the river channel. Thus, the series combination of the core purification module structure and the ecological restoration module structure is particularly suitable for severely black and odorous rivers.
[0026] One point to add is that the microbial carriers and adsorption fillers in filter cylinder 101 and filter cylinder 202 adopt a stacked design, which can be quickly replaced; the aquatic plants on the ecological restoration frame mesh plate 117 need to be harvested regularly to avoid rotting and pollution; when adding baking soda, the cylinder 103 can be removed directly for replenishment; when the cylinder 103, cylinder plate 104 and purification cylinder 1 are in contact with each other, the resulting medicine placement chamber will be sealed and no water will enter.
[0027] The modular approach to the coordinated treatment of black and odorous water in rivers and the steps for its operation and use are as follows: Step 1: The river water passively passing through filter cylinder 101 will be filtered by the mixed packing material of activated carbon and zeolite (mass ratio 1:2), which adsorbs and filters residual organic matter and heavy metal ions in the water. When passing through filter cylinder 202, the modified ceramic granules placed there will carry a complex microbial community (Bacillus subtilis, nitrifying bacteria, denitrifying bacteria, etc.), which can degrade pollutants such as COD, ammonia nitrogen, and total phosphorus, achieving a double-layer adsorption and purification effect. Step 2: At the same time, aquatic plants such as calamus, canna and foxtail grass are planted in the frame mesh 117. These plants have well-developed root systems and are resistant to pollution. The plant roots form a "biofilm" to further adsorb and degrade pollutants, while providing a habitat for microorganisms. In addition, the bio-rope filler 118 suspended at the bottom of the frame mesh 117 can enhance the attachment of microorganisms. Step 3: Before placing the purification cylinder 1 and frame mesh plate 117, insert the support column 208 into the two flanges 119. Then, manually activate the telescopic electric cylinder 202 on the upright plate 201 to drive the toothed plate in the meshing assembly 203 to move down, meshing the drive gear to rotate, thereby driving the bidirectional threaded rod 204 to rotate. The rotation of the bidirectional threaded rod 204 can drive the sleeve plate 206 on the rod body to guide and translate the clamping shaft plate 207 on the support column 208 until the multiple shafts on the clamping shaft plate 207 are slidably clamped into the flanges 119, and the two are quickly assembled and connected.

The bio-rope filler (118) is suspended at the bottom of the frame mesh (117) to enhance the attachment of microorganisms. Step 3: Before placing the purification cylinder (1) and the frame mesh plate (117), insert the support column (208) into the two flanges (119). Then, manually start the telescopic electric cylinder (202) on the upright plate (201) to drive the toothed plate in the meshing assembly (203) to move down, meshing the drive gear to rotate, thereby driving the bidirectional threaded rod (204) to rotate. The rotation of the bidirectional threaded rod (204) can drive the sleeve plate (206) on the rod body to drive the clamping shaft plate (207) to guide and translate on the support column (208) until the multiple shafts on the clamping shaft plate (207) are slidably clamped into the flange (119) for quick assembly and connection.
