Description

Technical Field

[0001] The present invention relates to the technical field of river water pollution treatment, and particularly relates to a purification treatment device and process for treating river water pollution. Background Art

[0002] River water pollution directly threatens the ecological environment and human health, and systematic treatment is required to ensure sustainable development. The significance of treatment lies in: protecting the ecology: restoring the biodiversity of aquatic organisms and maintaining the ecological balance; ensuring safety: providing clean water sources and reducing public health risks; promoting development: promoting the green economy and achieving a win-win situation for both ecology and economy.

[0003] During the process of river water pollution treatment, the purifier technology needs to be adopted. The purifier technology is a water purification method developed from the sewage treatment process. Microorganisms attach and grow on the surface of suspended fillers to form a microbial film layer with a certain thickness. The fillers float in the water body with the water flow under the disturbance of aeration, driving the attached biological flora to come into full contact with the pollutants and oxygen in the water body. The pollutants enter the biofilm through adsorption and diffusion and are degraded by microorganisms.

[0004] In actual application, since the biological fillers of the purifier need to be immersed in the river, due to the influence of seasonal changes or rainfall, the water flow in the river will accelerate. Therefore, under the impact of the water flow, it is very easy to wash the biological fillers away from the purifier. In the current existing technology, before the rainy season comes, the purifier is usually directly removed from the river manually, and this operation method is relatively cumbersome. Summary of the Invention

[0005] The purpose of the present invention is to provide a purification treatment device and process for treating river water pollution, and solve the following technical problems:

[0006] When the water flow in the river accelerates, it is very easy to wash away the biological fillers attached to the purifier.

[0007] The purpose of the present invention can be achieved by the following technical solutions:

[0008] A purification treatment device for treating river water pollution includes a purifier frame;

[0009] A number of columns of biological filler modules are arranged in an array in the purifier frame. Each column of biological filler modules includes filler support rods that are fixed in the purifier frame at equal distances, and a number of groups of filler bodies are uniformly arranged along the axial direction of each group of filler support rods;

[0010] Flow guiding modules for guiding the water flow are symmetrically arranged on both sides of the purifier frame respectively, and each group of flow guiding modules corresponds to each column of biological filler modules one by one.

[0011] Preferably, each group of the diversion modules includes a first diversion plate and a second diversion plate rotatably arranged on the purifier frame, and the first diversion plate and the second diversion plate are symmetrically arranged with the biological filler module as the center. The diversion module further includes a driving part for driving the first diversion plate and the second diversion plate to rotate towards each other or away from each other.

[0012] Preferably, the first diversion plate and the second diversion plate are respectively rotatably arranged on the purifier frame through support shafts, and the tops of the support shafts extend above the purifier frame and are fixedly connected with gears;

[0013] Among them, the driving part includes a U-shaped frame arranged between two groups of gears. Rack teeth meshing with the gears are symmetrically and fixedly arranged on the U-shaped frame, and the U-shaped frame is connected with a pulling mechanism for driving its reciprocating motion.

[0014] Preferably, inclined guide surfaces are provided at the ends of the first diversion plate and the second diversion plate close to each other.

[0015] Preferably, both ends of the filler support rod are respectively fixed to a first mounting plate and a second mounting plate fixedly arranged on the purifier frame.

[0016] Preferably, a floating bladder is provided on the purifier frame, and the floating bladder is fixed to the first mounting plate.

[0017] Preferably, the pulling mechanism includes wire wheels rotatably arranged symmetrically on both sides of the floating bladder. The side of the wire wheel away from the floating bladder is fixed to a runner, and several groups of blades are fixedly arranged in a circumferential array on the runner. Pulling ropes are symmetrically and fixedly arranged on the wire wheels;

[0018] Among them, the U-shaped frame is slidably sleeved on a positioning rod. The positioning rod is fixed to a positioning plate fixed on the first mounting plate. A telescopic spring is arranged on the positioning rod. One end of the telescopic spring is fixed to the U-shaped frame, and the other end is fixed to the positioning plate. A limiting rod is fixedly arranged at the end of the U-shaped frame close to the floating bladder. The other end of the limiting rod is fixed to a baffle plate, and the baffle plate is fixed to an adjusting plate. The other end of the pulling rope is fixed to the adjusting plate.

[0019] Preferably, the bottom of the purifier frame is fixed to the riverbed through an anchoring device.

[0020] Preferably, an aeration module is arranged at the bottom of the purifier.

[0021] A purification treatment process for treating river water pollution, applied to the above purification treatment device for treating river water pollution, includes the following steps:

[0022] Place the purifier in the river;

[0023] When the water flow velocity in the river does not exceed a predetermined value, the water flow can flow against each row of biological filler modules;

[0024] When the water flow velocity in the river channel exceeds a predetermined value, the diversion module guides the water flow to make the water flow along the gaps between each column of biological packing modules;

[0025] When the flow velocity in the river decreases again, the diversion module can automatically reset.

[0026] Advantages of the present invention:

[0027] (1) In the present invention, when the water flow velocity in the river channel does not exceed the predetermined value, the water flow can flow against each column of biological packing modules, so that the water in the river channel can directly contact the packing body of each column of biological packing modules, effectively removing pollutants such as organic pollutants, ammonia nitrogen, and total phosphorus in the water body and improving the water quality. Correspondingly, since there are installation gaps between two adjacent biological packing modules, when the water flow velocity in the river channel exceeds the predetermined value, the present invention can guide the water flow through the diversion module to make the water flow along the gaps between each column of biological packing modules, thereby effectively avoiding the water flow flowing against the biological packing modules and preventing the packing body from being washed out from the packing support rod. The stability of the packing body is higher. Therefore, even when the rainy season comes, there is no need to manually remove the purifier directly from the river channel, reducing the labor cost. At the same time, when the flow velocity in the river decreases, the diversion module can automatically reset, enabling the water in the river channel to fully contact the packing body for water quality purification treatment;

[0028] (2) In the present invention, when the water flow velocity in the river channel does not exceed the predetermined value, the first diversion plate and the second diversion plate are in a parallel state, and thus a diversion channel is formed between the first diversion plate and the second diversion plate, enabling the water to flow against the biological packing modules. When the water flow velocity in the river channel exceeds the predetermined value, the first diversion plate and the second diversion plate are driven by the driving part to move towards each other and come into contact, thereby closing the diversion channel. Since the first diversion plate and the second diversion plate are in an inclined state in this state, the water flow first impacts on the inclined surface of the diversion plate for buffering to achieve the effect of reducing the water flow velocity, and then the water flow can flow along the gaps between the biological packing modules, avoiding directly scouring the packing body;

[0029] (3) When the purifier of the present invention floats in the river channel, part of the blades of the runner can be immersed in the water. Therefore, when the water flow in the river channel speeds up, the blades can be impacted, and the blades can drive the runner to rotate synchronously. The runner then drives the wire winding wheel to rotate. During the rotation of the wire winding wheel, the adjusting plate is driven to move towards the floating bladder through the pull rope. The adjusting plate synchronously drives the U-shaped frame to move through the baffle and the limiting rod, so as to drive the first guide plate and the second guide plate to rotate towards each other. During this process, the U-shaped frame slides on the positioning rod and stretches the telescopic spring to generate an elastic force. Therefore, when the water flow in the river channel speeds up, the first guide plate and the second guide plate can be automatically adjusted to rotate towards each other under the action of the water flow impact. When the water flow velocity eases again, the telescopic spring can drive the U-shaped frame and each component to reset, without manual adjustment, and the degree of automation is higher.

Detailed implementation manners

[0040] Next, the technical solutions of the present invention will be clearly and completely described in conjunction with the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0041] Embodiment 1

[0042] Please refer to Figures 1 - 3 As shown, the present invention is a purification treatment device for treating river water pollution, including a purifier frame 1; specifically, the purifier frame 1 of this embodiment is a rectangular frame, which is composed of several groups of angle steels combined. Each angle steel can be fixed by bolts or welding. Among them, the size of the purifier frame 1 can be set accordingly based on the width and depth of the river to be treated. This embodiment does not limit this.

[0043] A number of columns of biological packing modules are arranged in an array in the purifier frame 1. Each column of biological packing modules includes packing support rods 103 fixed equidistantly in the purifier frame 1. A number of groups of packing bodies 104 are evenly arranged along the axial direction of each group of packing support rods 103; specifically, the packing body 104 of this embodiment is one or several of polyurethane, polyamide, polyethylene, polypropylene, polyolefin, aldehyde fiber silk or polyester silk; this embodiment does not limit this. The packing body 104 provides a suitable environment and carrier for the growth and reproduction of microorganisms and rapid film formation.

[0044] In addition, ceramic packing can also be used. As biological packing, ceramic packing has broad application prospects in river purification. It can fix microorganisms on the surface of the packing to form a stable biofilm. Through the metabolic activities of microorganisms, it can effectively remove organic pollutants, ammonia nitrogen, total phosphorus and other pollutants in the water body and improve water quality;

[0045] As a further solution of this embodiment, flow guiding modules 4 for guiding the water flow are symmetrically arranged on both sides of the purifier frame 1, and each group of flow guiding modules 4 corresponds to each column of biological filler modules one by one; specifically, when the water flow velocity in the river does not exceed a predetermined value, the water flow can flow towards each column of biological filler modules (see Figure 4 ), so that the water in the river can directly contact the filler body 104 of each column of biological filler modules, effectively removing pollutants such as organic pollutants, ammonia nitrogen, and total phosphorus in the water body, improving water quality. Correspondingly, since there is an installation gap between two adjacent biological filler modules, when the water flow velocity in the river exceeds the predetermined value, this embodiment can guide the water flow through the flow guiding module 4 (see Figure 5 ), guiding the water to flow along the gap between each column of biological filler modules, thereby effectively avoiding the water flow flowing towards the biological filler modules and preventing the filler body 104 from being washed out from the filler support rod 103. The stability of the filler body 104 is higher. Therefore, even when the rainy season comes, there is no need to manually remove the purifier from the river, reducing the labor cost. At the same time, when the flow velocity in the river decreases, the flow guiding module 4 can automatically reset, enabling the water in the river to fully contact the filler body 104 for water quality purification treatment.

[0046] Embodiment 2

[0047] On the basis of Embodiment 1, please refer to Figures 3 - 6 . Each group of flow guiding modules 4 includes a first flow guiding plate 401 and a second flow guiding plate 402 rotatably arranged on the purifier frame 1, and the first flow guiding plate 401 and the second flow guiding plate 402 are symmetrically arranged with the biological filler module as the center. The flow guiding module 4 further includes a driving part for driving the first flow guiding plate 401 and the second flow guiding plate 402 to rotate towards each other or away from each other; it can be explained that when the water flow velocity in the river does not exceed the predetermined value, the first flow guiding plate 401 and the second flow guiding plate 402 are in a parallel state, and thus a flow guiding channel is formed between the first flow guiding plate 401 and the second flow guiding plate 402, enabling the water to flow towards the biological filler module (see Figure 4 ). When the water flow velocity in the river exceeds the predetermined value, the driving part drives the first flow guiding plate 401 and the second flow guiding plate 402 to approach and contact each other, thereby closing the flow guiding channel. Since the first flow guiding plate 401 and the second flow guiding plate 402 are in an inclined state in this state, the water flow first impacts on the inclined surface of the flow guiding plate for buffering to achieve the effect of reducing the water flow velocity, and then the water flow can flow along the gap between the biological filler modules, avoiding directly scouring the filler body 104.

[0048] Accordingly, since the diversion module 4 is symmetrically arranged on both sides of the purifier frame 1, the effect of guiding and buffering the water flow can be achieved regardless of the water flow direction, and the applicable range is wider.

[0049] In this embodiment, please refer to Figures 6 - 8 , the first diversion plate 401 and the second diversion plate 402 are respectively rotatably arranged on the purifier frame 1 through the support shafts 404. The top of the support shaft 404 extends above the purifier frame 1 and is fixedly connected to the gear 405. Among them, the driving part includes a U-shaped frame 307 arranged between the two groups of gears 405. Rack bars 308 meshing with the gears 405 are symmetrically and fixedly arranged on the U-shaped frame 307. The U-shaped frame 307 is connected to a pulling mechanism that drives its reciprocating movement; it can be explained that when it is necessary to adjust the first diversion plate 401 and the second diversion plate 402 to approach each other or move away from each other, the U-shaped frame 307 is driven to slide through the pulling mechanism. During the movement of the U-shaped frame 307, the rack bar 308 can be synchronously driven to move. The rack bar 308 drives the support shaft 404 to rotate by meshing with the gear 405, and the support shaft 404 can synchronously drive the first diversion plate 401 and the second diversion plate 402 to rotate.

[0050] In addition, inclined guide surfaces 403 are provided at the ends of the first diversion plate 401 and the second diversion plate 402 that are close to each other; it can be explained that when the first diversion plate 401 and the second diversion plate 402 rotate towards each other, the inclined guide surfaces 403 on both sides can be completely attached to further improve the sealing performance of the connection between the first diversion plate 401 and the second diversion plate 402.

[0051] In order to install and fix each biological filler module, please refer to Figure 2 , both ends of the filler support rod 103 are fixedly connected to the first mounting plate 102 and the second mounting plate 101 fixedly arranged on the purifier frame 1; specifically, the filler support rod 103 can be fixed to the first mounting plate 102 and the second mounting plate 101 by means of bolt connection, so as to facilitate disassembly and replacement of the filler.

[0052] In addition, in order to enable the purifier to float on the river, in this embodiment, a floating bladder 2 is provided on the purifier frame 1, and the floating bladder 2 is fixedly connected to the first mounting plate 102; specifically, in this embodiment, by setting the floating bladder 2, the purifier can float on the river, and the filler body 104 can be immersed in water (please refer to Figure 1 ).

[0053] Please refer to Figures 1 - 3 and Figure 7, the pulling mechanism includes winding wheels 302 symmetrically and rotatably arranged on both sides of the floating bladder 2. One side of the winding wheel 302 away from the floating bladder 2 is fixed to the rotating wheel 3. A number of groups of blades 301 are fixedly arranged on the rotating wheel 3 in a circumferential array. Pulling ropes 303 are symmetrically and fixedly arranged on the winding wheels 302. Among them, the U-shaped frame 307 is slidably sleeved on the positioning rod 501. The positioning rod 501 is fixed to the positioning plate 5 fixed on the first mounting plate 102. A telescopic spring 502 is provided on the positioning rod 501. One end of the telescopic spring 502 is fixed to the U-shaped frame 307, and the other end is fixed to the positioning plate 5. A limiting rod 306 is fixedly arranged at one end of the U-shaped frame 307 close to the floating bladder 2. The other end of the limiting rod 306 is fixed to the baffle 305. The baffle 305 is fixed to the adjusting plate 304. The other end of the pulling rope 303 is fixed to the adjusting plate 304. It can be explained that when the purifier floats in the river, some of the blades 301 of the rotating wheel 3 can be immersed in the water (see Figure 1 ). Therefore, when the water flow in the river speeds up, the blades 301 can be impacted. The blades 301 can drive the rotating wheel 3 to rotate synchronously. The rotating wheel 3 then drives the winding wheel 302 to rotate. During the rotation of the winding wheel 302, the adjusting plate 304 is driven to move towards the floating bladder 2 through the pulling rope 303. The adjusting plate 304 drives the U-shaped frame 307 to move synchronously through the baffle 305 and the limiting rod 306 to drive the first guide plate 401 and the second guide plate 402 to rotate towards each other. During this process, the U-shaped frame 307 slides on the positioning rod 501 and stretches the telescopic spring 502 to generate elastic force. Therefore, when the water flow in the river speeds up, the first guide plate 401 and the second guide plate 402 can be automatically adjusted to rotate towards each other under the action of the water flow impact. When the water flow velocity eases again, the telescopic spring 502 can drive the U-shaped frame 307 and each component to reset, without manual adjustment, and the automation degree is higher.

[0054] As a further solution of this embodiment, please refer to Figure 1 , in order to stabilize the purifier in the river, the bottom of the purifier frame 1 is fixed to the riverbed through an anchoring device. The anchoring device can adopt an anchor chain or an anchor rod, which can improve the stability of the purifier in the river and prevent the purifier from being washed away by the water flow.

[0055] Meanwhile, in this embodiment, an aeration module 202 is provided at the bottom of the purifier to forcibly introduce air into the river water body, providing sufficient dissolved oxygen for the respiration of microorganisms. This is crucial for the biological filler to purify the river, as microorganisms consume a large amount of oxygen when degrading organic pollutants. The aeration equipment ensures that the microbial community can maintain efficient aerobic metabolic activities, thereby accelerating the decomposition of organic pollutants. While oxygenating, it also plays a role in stirring and mixing. It can keep various substances in the river water body in a suspended state, promoting sufficient contact between the microorganisms on the biological filler and the organic pollutants in the water body, and improving the biological treatment efficiency. In addition, the stirring effect helps prevent the settlement of suspended substances in the water body, maintaining the uniformity and stability of the water body.

[0056] It should also be noted that a photovoltaic power generation module 201 is further provided on the floating bladder 2 to convert solar energy into electrical energy to supply power to the aeration air pump.

[0057] In addition, a floating bed body and a floating bed substrate can be arranged on the floating bladder 2, and floating bed plants are arranged on the floating bed substrate (reference can be made to Figure 1 ); the floating bed body is preferably made of polystyrene foam board or inorganic materials such as ceramsite, vermiculite, and perlite; the floating bed substrate is preferably made of sponge, coconut fiber, etc.; the floating bed plants include but are not limited to cattail, canna, reed, water celery, water hyacinth, calamus, miscanthus sacchariflorus, rice, vetiver grass, acorus tatarinowii, water hyacinth, water spinach, etc.; in actual work, plant screening should be carried out according to influencing factors such as the on-site climate and water quality conditions; the floating bed plants are preferably local species with developed roots and strong rhizome propagation ability; the plants grow fast and have a large biomass; the plants are beautiful and have certain ornamental value; they have certain economic value.

[0058] A purification treatment process for treating river water pollution includes the following steps:

[0059] Please refer to Figures 1 - 3 , S1. Place the purifier in the river;

[0060] S2. When the water flow velocity in the river does not exceed the predetermined value, the water flow can flow against each column of biological filler modules (reference can be made to Figure 4 );

[0061] S3. When the water flow velocity in the river exceeds the predetermined value, the diversion module 4 guides the water flow (reference can be made to Figure 5 ), guiding the water to flow along the gaps between each column of biological filler modules;

[0062] S4. When the water flow velocity in the river decreases again, the diversion module 4 can automatically reset.
