[0006] To achieve the above objectives, the first aspect of this application provides: an intelligent treatment device for aquaculture wastewater based on water pollution control, comprising:

[0007] The treatment chamber has at least one water inlet, and the water inlet is connected to the treatment chamber.

[0008] A bar screen is disposed between the water inlet and the treatment chamber;

[0009] A bubble disperser is installed at the bottom of the treatment chamber to generate bubbles in the wastewater inside the treatment chamber.

[0010] A drive unit, located inside the processing chamber, is extendable and retractable along its height.

[0011] A first filter module and a second filter module are installed back-to-back and stacked on top of each other. The first filter module and the second filter module are connected to the driving unit and driven by the driving unit to achieve flipping.

[0012] The second filter module is connected to the first filter module, so that when the drive unit drives the second filter module to slide toward the wastewater, part of the wastewater is flushed by the second filter module against the first filter module.

[0013] In some embodiments, the drive unit includes a telescopic rod, a chuck, a mounting bracket, and a servo motor. The telescopic rod is installed inside the processing chamber and is coaxially arranged with the processing chamber. The chuck is installed at the telescopic end of the telescopic rod so that the chuck slides along the height direction under the drive of the telescopic rod.

[0014] The mounting bracket is installed inside the chuck, the first filter module and the second filter module are respectively installed on the upper and lower sides of the mounting bracket, the servo motor is located inside the chuck, and the output shaft of the servo motor extends to the outside of the chuck and is connected to the first filter module and the second filter module.

[0015] In some embodiments, the mounting frame is configured with at least four frames, the frames are connected to the output shaft of the servo motor, and an elastomer is disposed on the side of the frame facing the inner wall of the processing chamber, and the installation gap between the first filter module and the second filter module changes the compression state of the elastomer.

[0016] The adjacent frames are in contact with each other and are arranged in a stepped shape so that the frames are rotated when the servo motor drives them clockwise and when the servo motor drives them counterclockwise to fit together. A sealing strip is provided between the frames.

[0017] In some embodiments, the elastomer is embedded inside the frame, the contact positions of the first filter module and the second filter module with the elastomer are inclined, and the first filter module and the second filter module are connected to the frame by bolts, and the first filter module and the second filter module squeeze the elastomer during installation;

[0018] The elastomer has a hollow cavity inside, so that when the elastomer is squeezed, it expands toward the inner wall of the processing chamber.

[0019] The frame is equipped with a sealing groove that cooperates with the sealing strip, and the cross-sectional size of the sealing strip is larger than the cross-sectional size of the sealing groove, so that the sealing strip deforms when adjacent frames are in contact.

[0020] In some embodiments, the first filtration module includes a frame, blades, a screen, a first filter plate, a filter cloth, and fins. The frame is installed on the outside of the frame, the blades are located inside the frame and can rotate relative to the frame, and the screen is installed on one side of the frame opening.

[0021] The first filter plate is inclinedly disposed inside the frame, and the filter cloth is disposed on the side of the frame closer to the second filter module.

[0022] In some embodiments, the first filter plate includes a first inclined surface and a second inclined surface, so that when the second filter module slides toward the wastewater, the wastewater passes through the second filter module and impacts the first inclined surface and the second inclined surface;

[0023] The fins are located on the side of the frame closer to the chuck, so that when the bubble enters between the fins, it adheres to the surface of the fins.

[0024] In some embodiments, a collection chamber is provided outside the processing chamber, the collection chamber being configured with a pump assembly to form a communication with the processing chamber, the pump assembly having a pipe extending into the interior of the processing chamber.

[0025] The pipe extends to the inside of the chuck and communicates with the first filter module. A sealing ring is provided between the chuck and the frame so that when the pipe corresponds to the first filter module, the pipe communicates with the first filter module, and when the pipe is misaligned with the first filter module, the sealing ring seals the pipe.

[0026] In some embodiments, the second filtration module includes a plate, a first flow channel, a second filter plate, and a float plate. The plate is connected to the frame. The first flow channel extends from the surface of the plate to the interior of the plate. The second flow channel communicates with the first flow channel. The second filter plate is disposed at the junction of the first flow channel and the second flow channel.

[0027] The float is disposed inside the plate body and can float relative to the plate body. A first magnetic plate and a second magnetic plate are provided between the float and the plate body. The first magnetic plate is embedded inside the plate body and the second magnetic plate is embedded inside the float, so that the float floats under the combined action of water flow impact and the magnetic force of the first magnetic plate and the second magnetic plate.

[0028] In some embodiments, a ring frame is provided inside the processing chamber, and a drive unit is arranged inside the ring frame to drive the ring frame to rotate circumferentially along the axis of the processing chamber. A cleaning brush is embedded on the side of the ring frame facing the first filter module or the second filter module.

[0029] A water tank is disposed on the inner side of the plate. The water tank is connected to the pipe when the first filter module is facing the wastewater, and the water tank is connected to the first flow channel.

[0030] The second aspect of this application provides a method for treating aquaculture wastewater, comprising the following steps:

[0031] Start the equipment and check the bar screen, aeration, telescopic drive, servo, pump, and sensors;

[0032] Turn on the water inlet; the screen will intercept and remove large particles.

[0033] Activate the bubble disperser to create an upward airflow that promotes the floating of suspended matter;

[0034] The first filtration module treats the wastewater once, and then it is flipped through the second filtration module for further filtration.

[0035] When the pressure difference or turbidity exceeds the threshold, the drive unit slides / flips and works in conjunction with bubble flushing to perform online cleaning.

[0036] Real-time monitoring of effluent and sensor data automatically adjusts aeration, cleaning frequency, and pump speed;

[0037] In case of abnormality, a graded response should be implemented, and filter cloths and vulnerable parts should be replaced regularly.

[0038] This device achieves efficient interception of suspended solids and particulate pollutants in wastewater, online self-cleaning, and water resource recycling through the coordinated control of bar pre-interception, bubble-assisted separation, retractable and flip-up double-layer filtration module, magnetic levitation self-cleaning and annular brush mechanical cleaning, and backflow backwashing. This significantly improves effluent quality, extends continuous operation time, reduces the frequency of manual maintenance and operating costs, and facilitates modular expansion and intelligent operation and maintenance.

[0039] When the second filter module slides or flips relative to the first filter module and is flushed with air bubbles, the first filter module can be flushed and self-cleaned online. This mechanism can remove deposits without stopping the machine or under short-term low load, significantly reducing the number of manual cleanings, extending the life of the filter cloth and filter plate, and reducing the loss of processing capacity caused by cleaning downtime.

[0061] The embodiments of the technical solution of this application will now be described in detail with reference to the accompanying drawings. These embodiments are only used to more clearly illustrate the technical solution of this application and are therefore merely examples, and should not be used to limit the scope of protection of this application.

[0062] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of this application. The terms “comprising” and “having”, and any variations thereof, are intended to cover non-exclusive inclusion.

[0063] In the description of the embodiments of this application, the technical terms "first," "second," "third," etc., are used only to distinguish different objects and should not be construed as indicating or implying relative importance or implicitly specifying the number, specific order, or primary and secondary relationship of the indicated technical features. In the description of the embodiments of this application, "multiple" means two or more, unless otherwise explicitly defined.

[0064] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0065] In the description of the embodiments of this application, unless otherwise expressly specified and limited, technical terms such as "installation" and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. For those skilled in the art, the specific meaning of the above terms in the embodiments of this application can be understood according to the specific circumstances.

[0067] As a result, foam separation technology emerged. Foam separators have a significant enrichment capacity for fine particles ≤90μm in aquaculture circulating water, but their effectiveness is limited for particles >90μm and dissolved pollutants.

[0068] Foam separation is ineffective at removing particles >90μm and dissolved pollutants, mainly because large particles are not easily collided with bubbles and enriched, and dissolved molecules lack surface activity or hydrophobicity and cannot be carried by bubbles.

[0069] See Figure 1-14 As shown in the figure, this application provides an intelligent treatment device for aquaculture wastewater based on water pollution control, including a treatment chamber 100. The treatment chamber 100 is the core, and it has at least one inlet. A grid 200 is installed between the inlet and the treatment chamber 100 to intercept large particles and feed residue. A bubble disperser 300 is arranged at the bottom of the treatment chamber 100 to generate fine rising bubbles within the chamber to enhance solid-liquid separation and particle flotation.

[0070] The processing chamber 100 is equipped with a drive unit 400 that can extend and retract along its height and has a flipping drive function. The drive unit 400 is equipped with a first filter module 500 and a second filter module 600 for filtration. The two modules are stacked back to back and can be flipped, slid relative to each other and self-cleaned by rinsing under the action of the drive unit 400.

[0071] In some embodiments, a collection chamber 71 is provided on the outside of the treatment chamber 100. The collection chamber 71 is connected to the treatment chamber 100 through a pump assembly 72. The pipe 74 of the pump assembly 72 can extend to the inside of the chuck 42 and communicate with the first filter module 500 for extracting filtered water or performing fixed-point backwashing. An annular frame 75 and a cleaning brush 77 are provided inside the treatment chamber 100 for mechanically scrubbing the surface of the filter module.

[0072] The drive unit 400 comprises a telescopic rod 41, a chuck 42, a mounting frame 43, and a servo motor 44. The telescopic rod 41 is coaxially arranged along the axis of the processing chamber 100. The chuck 42 is mounted on the telescopic end of the telescopic rod 41. The chuck 42 slides with the telescopic rod 41 in the height direction to achieve the lifting and positioning of the module. The chuck 42 has a built-in servo motor 44. The output shaft of the servo motor 44 extends to the outside of the chuck 42 and connects to several frames 45 on the mounting frame 43. The mounting frame 43 is equipped with at least four frames 45, which are arranged in a stepped manner and driven by the output shaft of the servo motor 44 to achieve step-by-step flipping or fitting actions.

[0073] In addition, an elastic body 46 is embedded on the side of each frame 45 facing the inner wall of the processing chamber 100. A sealing strip 48 and a sealing groove 47 are provided between the frames 45. The cross-sectional dimension of the sealing strip 48 is slightly larger than that of the sealing groove 47 to generate deformation sealing when they are fitted together. When the servo motor 44 is driven clockwise, the frames 45 flip in a stepped sequence to expose or switch the filter surface; when driven counterclockwise, the frames 45 fit together step by step to achieve the sealing closure of the module. The combination of the chuck 42, the mounting bracket 43, and the servo motor 44 realizes the functions of module height positioning, flipping cleaning, and sealing closure.

[0074] This application does not limit the structure of the elastomer 46, and those skilled in the art can replace it according to the usage environment. For example, in the embodiments of this application, the elastomer 46 is a hollow rubber or elastic material.

[0075] The telescopic rod 41 and chuck 42 enable precise positioning of the module at different water levels or maintenance locations. The servo-driven stepped frame 45 enables step-by-step flipping and fitting, avoiding impact caused by large-scale movement at one time. The combination of the elastic body 46 and sealing strip 48 achieves reliable sealing and compensates for assembly tolerances.

[0076] In some embodiments, the first filter module 500 comprises a frame 51, blades 52, a screen 53, a first filter plate 54, a filter cloth 55, and fins 56. The frame 51 is fixed to the outside of the frame 45, and the screen 53 is located on the open side of the frame 51 to intercept larger particles; the blades 52 are installed inside the frame 51 and can rotate relative to the frame 51. The blades 52 rotate during cleaning or backwashing to loosen the attached substances.

[0077] The first filter plate 54 is inclined and includes a first inclined surface 541 and a second inclined surface 542. The filter cloth 55 covers the side near the second filter module 600 to achieve fine filtration. The fins 56 are arranged on the side of the frame 51 near the chuck 42. The gap between the fins 56 is a channel for bubbles to enter and attach. When the bubbles enter the gap between the fins 56, they can carry and cause particles to attach to the surface of the fins 56, thereby improving the filtration efficiency and slowing down the clogging speed of the filter cloth 55.

[0078] The frame 51 is stepped, and the protruding part of the frame 51 is the opening side of the frame 51. When the first filter module 500 is facing the wastewater, the opening side of the frame 51 will first extend into the wastewater.

[0079] When wastewater passes through the second filtration module 600 and impacts the inclined surface of the first filter plate 54, the impact helps to disperse suspended matter and cause particles to deposit on the filter cloth 55 or fins 56. The blades 52 rotate when needed to assist in cleaning or guide the deposits to the flushing channel.

[0080] The inclined filter plate, in conjunction with the filter cloth 55, fins 56 and bubble disperser 300, can achieve bubble-assisted adhesion, coarse and fine cascade filtration and mechanical-assisted cleaning, thereby extending the life of the filter cloth 55 and increasing the throughput.

[0081] In some embodiments, the second filtration module 600 includes a plate 61, a first flow channel 62, a second flow channel 63, a second filter plate 64, and a float plate 65. The plate 61 is connected to the frame 45. The first flow channel 62 is formed on the surface of the plate 61 and extends into the interior of the plate 61. The second flow channel 63 communicates with the first flow channel 62. The second filter plate 64 is disposed at the junction of the two flow channels to achieve graded interception.

[0082] The float plate 65 is disposed inside the plate body 61 and can float relative to the plate body 61. A first magnetic plate 66 and a second magnetic plate 67 are embedded between the float plate 65 and the plate body 61. The first magnetic plate 66 and the second magnetic plate 67 are magnetically engaged and repelled. The first magnetic plate 66 is embedded inside the plate body 61 and the second magnetic plate 67 is embedded inside the float plate 65. The magnetic force and the water flow impact work together to make the float plate 65 float under a certain flow rate or impact, thereby changing the flow channel opening or triggering a self-cleaning action.

[0083] When the flow rate or impact force increases, the float 65 is displaced under the action of magnetic force and water flow, changing the flow channel diameter or triggering the internal cleaning structure. When the float 65 resets, the magnetic force pulls it back to restore the filtration state. The impact of the water flow causes the float 65 to move upward, and then, under the magnetic force of the first magnetic plate 66 and the second magnetic plate 67, it pushes the water flow into the second flow channel 63, increasing the impact force of the water flow.

[0084] The water flowing into the second channel 63 will penetrate into the first filter module 500 along the filter cloth 55, impacting the surface residue of the first filter plate 54.

[0085] A water tank 68 may also be provided inside the plate 61 of the second filter module 600. The water tank 68 is connected to the return pipe 74 when the first filter module 500 is facing the wastewater, and is used for recycling or backwashing.

[0086] The passive-response design of the float plate 65 and magnetic plate reduces mechanical drive components, and can automatically adjust the effective filtration area and achieve local self-cleaning when the flow fluctuates.

[0087] The first filter module 500 and the second filter module 600 are stacked back-to-back and connected to the drive unit 400. The drive unit 400 can slide the second filter module 600 relative to the first filter module 500 or flip the two modules. When the second filter module 600 slides towards the wastewater, some wastewater passes through the second module and washes the surface of the first module at a certain speed. Combined with the rising bubbles and the rotation of the blades 52, the first filter module 500 can be washed and the attached substances can be loosened. The sealing ring between the chuck 42 and the frame 45 plays a sealing role when the pipe 74 is misaligned, preventing leakage during backwashing. The annular frame 75 and the cleaning brush 77 are activated when needed. The cleaning brush 77 rotates circumferentially with the annular frame 75 to mechanically scrub the surface of the filter module and remove stubborn attachments.

[0088] The combined use of multiple cleaning methods, including sliding flushing, bubble assistance, 52-degree blade rotation, and annular brushing, enables efficient self-cleaning during online operation, significantly extending continuous operating time and reducing the frequency of manual cleaning.

[0089] In some embodiments, a collection chamber 71 is provided outside the processing chamber 100. The collection chamber 71 is connected to the processing chamber 100 via a pump assembly 72. The pump assembly 72 has a pipe 74 extending into the processing chamber 100 and capable of docking with the chuck 42 / first filter module 500. When the pipe 74 corresponds to the first filter module 500, it forms a communication channel to extract filtered water or perform targeted backwashing. When the pipe 74 is misaligned with the first filter module 500, the sealing ring between the chuck 42 and the frame 45 is pressed to block the passage and prevent leakage. The pump assembly 72 can start the backwashing procedure at regular intervals or as needed, and the backwash water can be recycled to the collection chamber 71 for reuse.

[0090] Fixed-point backwashing and recycling reduce fresh water consumption, improve filter cloth cleaning efficiency, and lower operating costs.

[0091] This application also provides a method for treating aquaculture wastewater, the steps of which are as follows:

[0092] Start the equipment and check the bar screen 200, aeration, telescopic drive, servo, pump and sensors.

[0093] Turn on the water inlet; the 200-mesh screen will intercept and remove large particles.

[0094] Activate the bubble disperser 300 to create an upward airflow that promotes the floating of suspended matter.

[0095] The telescopic positioning filter module has a first filter module 500 that treats the wastewater once, and then flips over to pass it through the second filter module 600 for further filtration.

[0096] When the pressure difference or turbidity exceeds the threshold, the drive unit 400 slides / flips and works in conjunction with bubble flushing to perform online cleaning.

[0097] If necessary, start the ring brush mechanical scrubbing and use the pump to backwash the pipeline 74 to recover the backwash water.

[0098] It monitors the effluent and sensor data in real time, and automatically adjusts the aeration and cleaning frequency and pump speed.

[0099] In case of abnormality, a graded response should be implemented, and the filter cloth and vulnerable parts should be replaced regularly.

[0100] The above embodiments are merely illustrative of the technical solutions of this application and are not intended to limit it. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. These modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application, and all should be covered within the scope of this application. In particular, as long as there is no structural conflict, the various technical features mentioned in the embodiments can be combined in any way.
