Description

Technical Field

[0001] This invention relates to the field of water purification technology, specifically to a water purification device for water treatment. Background Technology

[0002] River and lake purifier technology is a water purification method that has evolved from wastewater treatment processes. Microorganisms attach and grow on the surface of suspended packing materials, forming a microbial biofilm of a certain thickness. Under the disturbance of aeration, the packing materials float with the water flow, allowing the attached microbial community to fully contact pollutants and oxygen in the water. Pollutants enter the biofilm through adsorption and diffusion, where they are degraded by the microorganisms. The attached microorganisms can achieve a very high biomass, therefore this process features high volumetric loading rate, strong denitrification capacity, stable operation, and excellent effluent quality.

[0003] In order to improve the water purification effect, the lake purifiers currently in use have relatively tight installation of each layer of packing frame, so that the water can be fully purified.

[0004] However, in practical applications, because the existing purifiers have fixed packing frames for each layer, during installation, the purifier is hoisted to the bottom of the river, and after operation, the packing frames no longer deform or shift. As the application of lake purifiers expands, in areas with unique hydrological characteristics, seasonal rainy seasons can accelerate the flow of water in the treated rivers. Due to the tightly packed packing frames, the purifiers pose a risk of obstructing flood flow, and large flows may cause them to be washed away or overturned. Summary of the Invention

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

[0006] The existing packing frames are installed very tightly. When the water flow is large, the lake purifier may block the flow of floodwater. A large flow may cause the lake purifier to be knocked over or washed away.

[0007] The objective of this invention can be achieved through the following technical solutions:

[0008] A water purification device for water treatment includes a water purifier installed in a river, wherein the water purifier includes two sets of parallel and symmetrically arranged first frames and second frames.

[0009] The first frame and the second frame are fixedly connected by two sets of parallel and symmetrical connecting frames; the first frame, the second frame, and the connecting frames together form the purifier frame;

[0010] The purifier frame contains several sets of biological packing supports arranged in an array. The purifier frame is also equipped with an adjustment module, which is used to adjust the spacing between the biological packing supports.

[0011] Preferably, each set of biological packing support includes a base frame and a top frame symmetrically arranged in the purifier frame, with several sets of packing rods fixedly arranged in an array between the base frame and the top frame, and several sets of packing bodies arranged in an array along the axial direction on the packing rods.

[0012] Preferably, two sets of guide rods are fixedly arranged in parallel and symmetrical arrangement in both the first frame and the second frame;

[0013] The base frame and the top frame are respectively fixed with guide seats that are slidably sleeved on the guide rods at both ends, and the two sets of guide seats are fixed by a limiting frame.

[0014] Preferably, the adjustment module includes a first adjustment seat fixedly arranged on the outside of each limiting frame, two sets of adjustment rods symmetrically arranged between two adjacent sets of first adjustment seats, each set of adjustment rods being hinged to the first adjustment seat, and the other end of each adjustment rod being hinged to the second adjustment seat;

[0015] In this configuration, a limiting seat is fixedly arranged at the end of the second adjusting seat away from the adjusting rod. Each limiting seat is slidably sleeved on the lifting rod, and the lifting rod is connected to the lifting module that drives its lifting and lowering.

[0016] Preferably, the number of biological packing supports is an odd number, and for the biological packing supports in the middle position, the guide seat is fixed on the guide rod.

[0017] Preferably, the lifting module includes L-shaped brackets fixedly arranged at both ends of the lifting rod, with a support rod fixed on the L-shaped bracket, the other end of the support rod fixed to the lifting seat, and the end of the lifting seat away from the support rod fixed to a rope;

[0018] The purifier frame has rotating wheels on both sides, the other end of a rope is fixed to the rotating wheels, and impellers are fixed on both sides of the rotating wheels.

[0019] Preferably, the purifier frame is also provided with pulleys that rotate, and the rope passes through the pulleys and is fixed to the lifting seat to guide and limit the rope.

[0020] Preferably, each of the lifting seats is slidably connected to a limiting rod fixedly arranged on the first frame and the second frame;

[0021] The limiting rod is also equipped with a telescopic spring; specifically, the present invention can also generate a certain resistance to the lifting of the lifting seat by setting the telescopic spring. When the water flow rate is insufficient to expand the spacing of the biological packing support, the impeller cannot rotate due to the existence of this resistance, and the position of the lifting seat will not change.

[0022] Preferably, anchor chains are fixedly installed at the bottom of the purifier frame.

[0023] Preferably, a float is fixedly arranged on the purifier frame, and a water purification carrier frame is fixedly arranged on the float. The impellers on both sides are rotatably connected to the mounting brackets fixed at both ends of the water purification carrier frame. Specifically, by setting the float, the water purifier is suspended in the water. Under the buoyancy of the float, the water purifier can be suspended in the water, and the impellers on both sides are always at the height of the water surface. Even if the water level in the river rises or falls, the relative position of the impellers and the water surface will not change.

[0024] The beneficial effects of this invention are:

[0025] (1) When purifying river water, the present invention hoists the water purifier into the river. In the initial state, the spacing between the biological filler supports of each layer is the smallest and the compactness is the highest, so that the water in the river can have more contact with the biological filler, thereby improving the water purification effect. When the river flow accelerates, in order to avoid the risk of the compact biological filler supports blocking the flood, the present invention can adjust the spacing between the biological filler supports of each layer in real time by adjusting the module, so that the spacing between the biological filler supports of each layer is larger. Therefore, the water flow can flow in the gap between the biological filler supports, thereby reducing the obstruction of the biological filler supports to the water flow, thereby improving the stability of the water purifier in the river and preventing it from being washed away by the water flow.

[0026] (2) After the water purifier of the present invention is placed in the river, the height of each impeller is just at the water surface. When the water flow in the river accelerates, the impeller can be driven to rotate under the impact force of the water. The impeller drives the rotating wheel to rotate synchronously, and then the rope can be wound around the rotating wheel. During the winding process, the lifting seat is lifted by the rope. The lifting seat can drive the lifting rod to rise through the support rod and L-shaped bracket to drive the spacing of each layer of biological filler support to expand. The present invention does not need to use other servo drive components to adjust the spacing of biological filler support. When the water flow speed in the river increases, the effect of automatically adjusting the spacing of biological filler support can be achieved, and the degree of automation and stability is higher.

[0027] (3) By setting a telescopic spring, the present invention can also generate a certain resistance to the lifting of the lifting seat. When the water flow rate is insufficient to expand the spacing of the biological packing support, the impeller cannot rotate due to the existence of this resistance, and the position of the lifting seat will not change.

[0028] (4) By setting up a float, the water purifier can be suspended in the water under the buoyancy of the float, and the impellers on both sides are always at the height of the water surface. Even if the water level in the river rises or falls, the relative position of the impellers and the water surface will not change.

[0029] (5) The water purification carrier frame of the present invention is located at the top of the water purifier. A floating bed and a floating substrate are set on the water purification carrier frame, and floating plants are set on the floating substrate. The floating bed is preferably made of polystyrene foam board or inorganic materials such as ceramsite, vermiculite, and perlite. The floating substrate is preferably made of sponge, coconut fiber, etc. The floating plants include, but are not limited to, cattail, canna, reed, water celery, water hyacinth, calamus, reed, rice, vetiver, sweet flag, water hyacinth, water lettuce, etc. In actual work, the plants should be selected according to the influencing factors such as the on-site climate and water quality conditions. The floating plants are preferably local species with well-developed root systems and strong rhizome reproduction ability. The plants grow quickly and have a large biomass. The plants are beautiful and have a certain ornamental value. They also have a certain economic value.

[0030] (6) This invention provides sufficient dissolved oxygen for microorganisms to respire by forcibly introducing air into the river water through an aeration module installed at the bottom of the water purifier. This is crucial for the purification of rivers by biological packing materials, 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 providing oxygen, it also acts as agitator and mixer. It keeps the various phases of matter in the river water in a suspended state, promoting full contact between the microorganisms on the biological packing materials and the organic pollutants in the water, thus improving biological treatment efficiency. Furthermore, the agitation helps prevent the settling of suspended solids in the water, maintaining the uniformity and stability of the water body. The water purifier is also equipped with a photovoltaic power generation module to convert solar energy into electrical energy to power the various servo devices of the water purifier.

Detailed Implementation

[0042] 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.

[0043] Example 1

[0044] Please see Figures 1-2 As shown, the present invention is a water purification device for water treatment, including a water purifier 1 installed in a river. The water purifier 1 includes two sets of parallel and symmetrically arranged first frames 101 and second frames 102. Specifically, in this embodiment, both the first frames 101 and the second frames 102 are set as rectangular frames.

[0045] The first frame 101 and the second frame 102 are fixedly connected by two sets of parallel and symmetrical connecting frames 103; the first frame 101, the second frame 102 and the connecting frames 103 enclose and form the purifier frame.

[0046] Please see Figures 2-3 The purifier frame contains several sets of biological packing supports arranged in an array. The purifier frame also contains an adjustment module, which is used to adjust the spacing between the biological packing supports.

[0047] It can be noted that, in this embodiment, when purifying river water, the water purifier 1 is hoisted into the river. In the initial state, the spacing between the biological packing supports of each layer is the smallest, and the compactness is the highest (see reference). Figure 7 This allows for more thorough contact between the water in the river and the biological packing material, thereby improving water purification. When the river flow accelerates, to avoid the risk of the compact biological packing material support obstructing flood flow, this embodiment allows for real-time adjustment of the spacing between each layer of biological packing material support via an adjustable module, resulting in a larger spacing between the layers (see reference...). Figure 8 Therefore, the water flow can flow through the gaps in the biological packing support to reduce the obstruction of the biological packing support to the water flow, thereby improving the stability of the water purifier 1 in the river and preventing it from being washed away or swept away by the water flow.

[0048] In addition, please see Figure 9 In this embodiment, an aeration module is installed at the bottom of the water purifier 1 to forcibly introduce air into the river water, providing sufficient dissolved oxygen for the respiration of microorganisms. This is crucial for the purification of rivers by biological packing materials, 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 activity, thereby accelerating the decomposition of organic pollutants. While oxygenating, it also acts as agitator and mixer. It keeps the various phases of matter in the river water in a suspended state, promoting full contact between the microorganisms on the biological packing materials and the organic pollutants in the water, improving biological treatment efficiency. Furthermore, the agitation helps prevent the settling of suspended solids in the water, maintaining the uniformity and stability of the water.

[0049] It should also be noted that the water purifier 1 is equipped with a photovoltaic power generation module to convert solar energy into electrical energy to power the various servo devices of the water purifier 1.

[0050] Example 2

[0051] Based on Example 1, please refer to Figures 2-4Each set of biological packing support includes a base frame 501 and a top frame 509 symmetrically arranged in the purifier frame. Several sets of packing rods 502 are fixedly arranged in an array between the base frame 501 and the top frame 509. Several sets of packing bodies 503 are arranged in an array along the axial direction of the packing rods 502. It can be noted that the packing body 503 in this embodiment is one or more of polyurethane, polyamide, polyethylene, polypropylene, polyolefin, aldehyde fiber filament or polyester filament. This embodiment does not limit this. The packing body 503 provides a suitable environment and carrier for the growth, reproduction and rapid biofilm formation of microorganisms.

[0052] In addition, ceramic packing materials can also be used. As biological packing materials, ceramic packing materials have broad application prospects in river purification. They can immobilize microorganisms on the surface of the packing material, forming a stable biofilm. Through the metabolic activities of microorganisms, they can effectively remove pollutants such as organic pollutants, ammonia nitrogen, and total phosphorus from the water, thereby improving water quality.

[0053] In this embodiment, when adjusting the spacing of each layer of biological packing support, to ensure that the biological packing support can slide stably within the purifier frame, please refer to [link to relevant documentation]. Figure 2 and Figure 4 In both the first frame 101 and the second frame 102, two sets of guide rods 104 are fixedly arranged in parallel and symmetrical manner. At the two ends of the base frame 501 and the top frame 509, guide seats 105 are respectively fixedly arranged and slidably sleeved on the guide rods 104. The two sets of guide seats 105 are fixed by the limiting frame 5. It can also be explained that when the adjustment module adjusts the spacing of each layer of biological filler support, each guide seat 105 slides synchronously on the guide rod 104 to improve the stability of the base frame 501 and the top frame 509 during movement.

[0054] As a further solution in this embodiment, please refer to Figures 5-6The adjustment module includes a first adjustment seat 504 fixedly arranged on the outside of each limiting frame 5. Two sets of adjustment rods 505 are symmetrically arranged between two adjacent sets of first adjustment seats 504. Each set of adjustment rods 505 is hinged to a first adjustment seat 504. The other end of each adjustment rod 505 is hinged to a second adjustment seat 506. A limiting seat 507 is fixedly arranged at the end of the second adjustment seat 506 away from the adjustment rods 505. Each limiting seat 507 is slidably sleeved on a lifting rod 508. The lifting rod 508 is connected to the lifting module that drives its lifting. It can be explained that, in this embodiment, when adjusting the spacing of each layer of biological packing support to increase, the lifting module first drives the lifting rod 508 to rise. During the lifting process, the lifting rod 508 pushes the two adjacent first adjusting seats 504 away from each other through the second adjusting seat 506 and the adjusting rod 505. The first adjusting seat 504 synchronously drives the biological packing support to move, so as to realize the adjustment of the spacing between the two adjacent biological packing supports. Correspondingly, when the lifting module drives the lifting rod 508 to fall, it drives each biological packing support to converge with each other.

[0055] In addition, please see Figures 2-5 In order to ensure the consistency of the spacing between two groups of adjacent biological packing supports during the movement of each biological packing support, in this embodiment, the number of biological packing supports is an odd number, and for the biological packing support in the middle position, its guide seat 105 is fixed on the guide rod 104. It can be noted that there are thirteen groups of biological packing supports in this embodiment, and the specific number is not limited, as long as it meets the actual water purification needs.

[0056] Please see Figures 2-4 The lifting module includes L-shaped brackets 404 fixedly arranged at both ends of the lifting rod 508. Support rods 403 are fixed on the L-shaped brackets 404, with the other end of the support rods 403 fixed to the lifting seat 4. The end of the lifting seat 4 away from the support rods 403 is fixed to a rope 301. Rotary wheels 3 are rotatably arranged on both sides of the purifier frame, with the other end of the rope 301 fixed to the wheel 3. Impellers 303 are fixedly arranged on both sides of the wheel 3. It can be explained that after the water purifier 1 is placed in the river, the height of each impeller 303 is exactly at the water surface. When the water flow in the river accelerates, the impellers 303 are impacted by the water... Under the action of force, the impeller 303 can be driven to rotate, and the impeller 303 synchronously drives the rotating wheel 3 to rotate, thereby winding the rope 301 around the rotating wheel 3. During the winding process, the lifting seat 4 is lifted by the rope 301. The lifting seat 4 can drive the lifting rod 508 to rise through the support rod 403 and the L-shaped bracket 404, so as to drive the spacing of each layer of biological filler support to expand. In this embodiment, there is no need to use other servo drive components to adjust the spacing of biological filler support. When the river water flow velocity increases, the effect of automatically adjusting the spacing of biological filler support can be achieved, with a higher degree of automation and stability.

[0057] In this embodiment, to ensure that the rope 301 can stably lift the lifting platform 4, please refer to... Figure 2 The purifier frame is also equipped with a pulley 302 that rotates, and the rope 301 passes through the pulley 302 and is fixed to the lifting seat 4 to guide and limit the rope 301.

[0058] Furthermore, in order to automatically adjust the repositioning of the biological packing support layers when the water flow velocity in the river channel decreases, in this embodiment, please refer to... Figure 3 Each lifting seat 4 is slidably connected to a limiting rod 401 fixedly arranged on the first frame 101 and the second frame 102. The limiting rod 401 is also provided with a telescopic spring 402. One end of the telescopic spring 402 is fixed to the lifting seat 4, and the other end is fixed to the end of the limiting rod 401. It can be noted that in this embodiment, when the lifting seat 4 is driven to rise, the lifting seat 4 slides on the limiting rod 401 and simultaneously compresses the telescopic spring 402 to generate elastic force. When the water flow slows down, the lifting seat 4 can be driven to return to its original position under the action of elastic force. It should also be noted that in this embodiment, by setting the telescopic spring 402, a certain resistance can also be generated for the lifting of the lifting seat 4. When the water flow rate is insufficient to expand the spacing of the biological packing support, the impeller 303 cannot rotate due to the existence of this resistance, and the position of the lifting seat 4 will not change.

[0059] In this embodiment, please refer to Figure 1 In order to further improve the stability of the water purifier 1 in the river, anchor chains 106 are fixedly installed at the bottom of the purifier frame. Specifically, after the water purifier 1 is hoisted into the river, the stability of the water purifier 1 in the river is further improved by each anchor chain 106, so that the water purifier 1 will not be easily washed away by the water flow.

[0060] In addition, the bottom of the purifier frame can also be positioned with the riverbed or river bottom using telescopic anchors, but this embodiment does not limit this.

[0061] Furthermore, a float 2 is fixedly arranged on the purifier frame, and a water purification carrier frame 201 is fixedly arranged on the float 2. The impellers 303 on both sides are rotatably connected to the mounting brackets fixed at both ends of the water purification carrier frame 201. Specifically, in this embodiment, by setting the float 2, after the water purifier 1 is hoisted into the water, the water purifier 1 can be suspended in the water under the buoyancy of the float 2, and the impellers 303 on both sides are always at the height of the water surface. Even if the water level in the river rises or falls, the relative position of the impellers 303 and the water surface will not change.

[0062] Furthermore, in this embodiment, the water purification carrier frame 201 is located on top of the water purifier 1. A floating bed and a floating bed substrate are provided on the water purification carrier frame 201, and floating bed plants are placed on the floating bed substrate (see reference...). Figure 1 The preferred materials for the floating bed are polystyrene foam board or inorganic materials such as expanded clay, vermiculite, and perlite. The preferred substrates are sponge and coconut fiber. Floating bed plants include, but are not limited to, cattails, canna lilies, reeds, water celery, water hyacinth, calamus, reeds, rice, vetiver, sweet flag, water hyacinth, and water lettuce. In practice, plant selection should be based on factors such as on-site climate and water quality. Preferred floating bed plants are local species with well-developed root systems, strong rhizome propagation capabilities, rapid growth, large biomass, attractive appearance, and economic value.

[0064] S1. Hoist the water purifier 1 into the river and fix it to the riverbed with anchor chain 106;

[0065] S2. In the initial state, the spacing between the layers of biological packing scaffold is the smallest, and the compactness is the highest (see reference). Figure 7 );

[0066] S3. When the river flow accelerates, the regulating module adjusts the spacing of the biological packing support in real time to increase the spacing between the biological packing support.
