Description

Technical Field

[0001] This invention relates to the field of wastewater treatment technology, and specifically to a modular containerized wastewater treatment device. Background Technology

[0002] With rapid economic and social development and the continuous improvement of people's living standards, the amount of wastewater discharged from industrial, agricultural and domestic sectors is constantly increasing, and its composition is becoming increasingly complex, causing serious pollution to the natural water environment. Water pollution prevention and control has become an important issue concerning ecological security and public health.

[0003] Currently, traditional centralized sewage treatment plants typically suffer from problems such as long construction periods, large land areas, high fixed investments, and complex pipeline networks, making it difficult to flexibly adapt to the sewage treatment needs of distributed pollution sources, temporary construction sites, emergency response, and remote areas.

[0004] In addition, although existing integrated sewage treatment equipment has a certain degree of integration, its treatment process is often fixed and single, making it difficult to flexibly adjust the treatment process according to the real-time fluctuations in the influent water quality. As a result, when faced with changes in water quality and quantity, either the treatment effect is unstable or the operating energy consumption is too high, resulting in waste of resources.

[0005] Therefore, how to realize a highly efficient wastewater treatment device that can be quickly deployed, flexibly expanded, and intelligently optimized according to water quality has become a problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0006] In order to overcome the shortcomings of existing sewage treatment facilities, such as high construction and operation costs, poor flexibility, and difficulty in intelligently adapting to changes in water quality, this application provides a modular containerized wastewater treatment device.

[0007] The modular containerized wastewater treatment device provided in this application adopts the following technical solution: A modular containerized wastewater treatment device includes a container on which an inlet assembly and an outlet assembly are installed. The inlet assembly is connected to a pretreatment module, which is connected to a water quality detection module. The water quality detection module is connected to a water flow distribution assembly, which is connected to a biological treatment module, a sedimentation and filtration module, and a disinfection module. The disinfection module is connected to the outlet assembly. The inlet assembly, the outlet assembly, the pretreatment module, the water quality detection module, the water flow distribution assembly, the biological treatment module, the sedimentation and filtration module, and the disinfection module are all electrically connected to an intelligent control system.

[0008] By adopting the above technical solution and using standard containers as carriers, the complete wastewater treatment process is highly integrated, enabling rapid transportation, hoisting, and deployment of the equipment. The modular design concept ensures that each functional unit is independent and has standardized interfaces, facilitating rapid on-site assembly and commissioning. Furthermore, the flexible series or parallel connection of multiple containers allows for easy expansion of processing capacity, perfectly adapting to various application scenarios from temporary emergency situations to long-term operations, and from small-scale to large-scale operations. This fundamentally solves the pain points of traditional wastewater treatment facilities, such as long construction cycles, large footprints, and poor flexibility. Moreover, through real-time water quality monitoring and intelligent control, it achieves quality-based diversion and precise treatment, avoiding unnecessary operation of process units and significantly reducing energy consumption and operating costs. It can automatically select the optimal treatment path based on different water qualities, improving the equipment's adaptability and stability in treating wastewater from different sources.

[0009] Furthermore, the water inlet assembly includes a water inlet pipe fixedly installed on the container, the water inlet pipe having a first connecting end, a second connecting end, and a third connecting end, the first connecting end and the second connecting end extending to the outside of the container, the third connecting end being connected to a first water pump, the output end of the first water pump being connected to the input end of the pretreatment module; the first water pump being electrically connected to the intelligent control system.

[0010] By adopting the above technical solution and utilizing an inlet pipe with a first connection end, a second connection end, and a third connection end, a single device can be connected to an external water source as an independent unit, or it can be quickly connected in series with other similar devices through the first and second connection ends to form a processing array, greatly improving the flexibility of system configuration. The built-in first water pump, under the command of the intelligent control system, realizes the automatic and controllable introduction of wastewater.

[0011] Furthermore, the water outlet assembly includes a water outlet pipe fixedly installed on the container, the water outlet pipe having a fourth connection end, a fifth connection end, and a sixth connection end, the fourth connection end and the fifth connection end extending to the outside of the container, the sixth connection end being connected to a second water pump, the input end of the second water pump being connected to the output end of the disinfection module; the second water pump is electrically connected to the intelligent control system.

[0012] By adopting the above technical solution, the design of the water outlet component echoes that of the water inlet component, also employing a multi-port design to ensure that the treated clean water can be flexibly discharged or connected to subsequent units. The second water pump provides the discharge power and can be linked with the intelligent control system to achieve timely and controllable discharge of compliant water, ensuring smooth water flow and pressure balance throughout the system.

[0013] Furthermore, the pretreatment module includes a pretreatment box, a pretreatment box cover is fixedly and sealed to the top of the pretreatment box, a pretreatment water inlet pipe is fixedly and sealed to the pretreatment box cover, the pretreatment water inlet pipe is connected to the output end of the water inlet assembly, a pretreatment water outlet pipe is fixedly and sealed to the bottom of the pretreatment box, and the pretreatment water outlet pipe is connected to the input end of the water quality detection module; at least two sets of drawer-type filter assemblies are sealed and slidably connected on the pretreatment box between the pretreatment water inlet pipe and the pretreatment water outlet pipe, and a pressure sensor is fixedly and sealed to the pretreatment box cover, the pressure sensor being electrically connected to the intelligent control system.

[0014] By adopting the above technical solution and utilizing a multi-layer drawer-type filter assembly, large suspended particles of different sizes in wastewater can be efficiently intercepted, protecting downstream precision equipment. Its sealed sliding connection, combined with a unique self-sealing structure, allows for safe and convenient cleaning or filter replacement of any drawer without shutting down the system, preventing system downtime due to maintenance. A pressure sensor monitors filtration resistance in real time, enabling blockage warnings and on-demand maintenance, improving the automation level and operational reliability of the pretreatment unit.

[0015] Furthermore, the water quality detection module includes a water quality detection box, the top of which is fixedly and sealed with a water quality detection box cover. The water quality detection box cover has a water quality detection input port, and the side wall of the water quality detection box near its bottom has a water quality detection output port, which is connected to the water flow distribution component. A water quality detection sensor is fixedly and sealed on the water quality detection box cover, and the water quality detection sensor is electrically connected to the intelligent control system.

[0016] By adopting the above technical solution, key indicators of wastewater can be monitored in real time and online using water quality sensors. This module provides the core decision-making basis for the intelligent control system and is the foundation for the device to achieve an intelligent closed loop of perception, decision-making, and execution, ensuring the scientific and accurate selection of subsequent process paths.

[0017] Furthermore, the water distribution assembly includes a main water distribution pipe, which is sealed to the water quality detection module. A first branch pipe, a second branch pipe, and a third branch pipe are fixedly and sealed to the main water distribution pipe. A first electric pump is installed on the first branch pipe, a second electric pump is installed on the second branch pipe, and a third electric pump is installed on the third branch pipe. The output end of the first electric pump is connected to the input end of the biological treatment module. The output end of the second electric pump is connected to a first tee pipe, and the other two ends of the first tee pipe are respectively connected to a fourth electric pump. The system includes a fourth electric pump connected to the output of the biological treatment module and a fifth electric pump connected to the input of the sedimentation and filtration module. A second three-way connector is connected to the output of the third electric pump, with one end of the second three-way connector connected to a sixth electric pump, which is also connected to the output of the sedimentation and filtration module. The other end of the second three-way connector is connected to the input of the disinfection module. All electric pumps (first, second, third, fourth, fifth, and sixth) are electrically connected to the intelligent control system.

[0018] By adopting the above technical solution, a flexible distribution network consisting of multiple independently controlled electric pumps and T-junction pipes is utilized. The intelligent control system, through programming control of the coordinated start and stop of these pumps, can accurately and reliably realize various preset and dynamically calculated water flow paths. This is the core actuator for the entire device to achieve intelligent and dynamic process reconfiguration.

[0019] Furthermore, the biological treatment module includes a biological treatment tank, a biological treatment tank cover installed on the top of the biological treatment tank, and an aeration device installed at the bottom of the biological treatment tank, the aeration device being electrically connected to the intelligent control system; a biological treatment inlet is provided on the outer side of the biological treatment tank near its top, a biological treatment outlet is provided on the outer side of the biological treatment tank near its bottom, and a biological treatment maintenance port is provided on the outer side of the biological treatment tank near its middle; the biological treatment inlet is connected to the water flow distribution component, and the biological treatment outlet is connected to the water flow distribution component; a maintenance cover is detachably and sealingly connected to the biological treatment maintenance port.

[0020] By adopting the above technical solution and utilizing the aeration device installed inside the biological treatment tank, a stable and efficient biochemical environment is created for aerobic microorganisms to degrade organic matter. The specially designed maintenance port for the biological treatment system eliminates the need to open the entire tank cover for maintenance tasks such as adding microbial agents, inspecting or replacing aeration heads, making operation simpler and safer, reducing interference with system operation, and improving the maintainability of the module.

[0021] Furthermore, the sedimentation filtration module includes a sedimentation filtration box, a sedimentation filtration input pipe is fixedly and sealed to the outside of the sedimentation filtration box near its top, a sedimentation filtration output pipe is fixedly and sealed to the outside of the sedimentation filtration box near its middle, and a slag discharge device is fixedly and sealed to the bottom of the sedimentation filtration box; a filtration device is installed inside the sedimentation filtration box below the sedimentation filtration input pipe, and a sedimentation chamber communicating with the slag discharge device is provided below the filtration device; the slag discharge device is electrically connected to the intelligent control system.

[0022] By adopting the above technical solution, the filtration device and sedimentation chamber are integrated into a single tank. Water first passes through the filter media to trap fine suspended solids and colloids, then enters the sedimentation zone for further solid-liquid separation. This integrated design of top filtration and bottom sedimentation significantly improves solid-liquid separation efficiency and effluent quality within a limited space. Simultaneously, the bottom sludge discharge device enables on-demand sludge discharge, ensuring the long-term stable operation of the module.

[0023] Furthermore, the disinfection module includes a disinfection tank, a lid is fixedly and sealed to the top of the disinfection tank, a disinfection input port is opened on the lid, the disinfection input port is sealed to the water flow distribution component, a disinfection output port is opened at the bottom of the disinfection tank, and the disinfection output port is sealed to the input end of the water outlet component; an ultraviolet disinfection device is installed inside the disinfection tank, and the ultraviolet disinfection device is electrically connected to the intelligent control system.

[0024] By adopting the above technical solution, the ultraviolet disinfection device is directly immersed in the disinfection tank. It has a compact structure, good sterilization effect, and simple operation and management. It is easy to realize automatic start-up and shutdown and intensity monitoring through intelligent control system, thus ensuring the biological safety of the final effluent.

[0025] Furthermore, the intelligent control system includes a PLC controller, which is connected to a signal transceiver module, and the signal transceiver module is connected to a mobile terminal; the PLC controller is electrically connected to the water inlet component, the water outlet component, the pretreatment module, the water quality detection module, the water flow distribution component, the biological treatment module, the sedimentation and filtration module, and the disinfection module.

[0026] By adopting the above technical solution, a centralized intelligent control system was constructed using a PLC controller. It serves not only as the coordination and command center for various physical units such as pumps, valves, sensors, and aerators, but also as the intelligent brain of the entire processing flow. Through connection with a mobile terminal via a signal transceiver module, remote monitoring, data viewing, parameter setting, and fault alarms of the device are realized. This allows maintenance personnel to grasp the operating status without being physically present on-site, greatly improving management efficiency and convenience, and truly achieving unattended or minimally staffed automated operation.

[0027] Beneficial effects achieved: The modular containerized wastewater treatment device provided in this application integrates the complete treatment process into a standard container and introduces an intelligent control system based on real-time water quality monitoring. This achieves quality-based diversion and precise treatment, resulting in multiple beneficial effects such as integration, intelligence, efficiency, and flexibility.

[0028] This application utilizes standard shipping containers as the carrier, enabling the equipment to possess excellent transportation convenience and site adaptability, allowing for rapid hoisting, docking, and commissioning. The modular and standardized interface design supports easy series or parallel connection of multiple container units, achieving linear expansion of processing capacity. This flexibly adapts to diverse scale needs, ranging from emergency treatment and temporary construction sites to small communities, fundamentally overcoming the inherent shortcomings of traditional wastewater treatment facilities, such as long construction cycles, large land areas, and poor flexibility.

[0029] This application uses a water quality detection module to monitor the influent water quality in real time, and an intelligent control system dynamically controls the water flow distribution components according to a preset strategy, achieving quality-based diversion and precise treatment of the process. Based on intelligent path selection using real-time water quality, it avoids the unnecessary energy consumption and operating costs associated with traditional fixed processes that treat all wastewater in a single step, achieving significant energy savings.

[0030] This application integrates multiple mature process units, including physical pretreatment, biodegradation, composite sedimentation filtration, and deep disinfection. Each module works collaboratively under the coordination of an intelligent system, ensuring the stability of treatment effects for wastewater of different qualities and the reliability of the final effluent meeting standards.

[0031] This application employs a drawer-type filter assembly and a biological treatment maintenance port design, making critical maintenance operations simpler and safer, and reducing operation and maintenance difficulty and labor costs. The PLC-based intelligent control system not only achieves fully automated operation and linkage control, but also supports remote monitoring, data management, and fault early warning through a signal transceiver module.

Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0044] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; 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; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0045] This application discloses a modular containerized wastewater treatment device.

[0046] Please refer to the above as well. Figures 1 to 9 In one embodiment of this application, a modular containerized wastewater treatment device includes a container 100. An inlet component 200 and an outlet component 300 are installed on the container 100. The inlet component 200 is connected to a pretreatment module 400, which is connected to a water quality detection module 500. The water quality detection module 500 is connected to a water flow distribution component 600, which is connected to a biological treatment module 700, a sedimentation and filtration module 800, and a disinfection module 900. The disinfection module 900 is connected to the outlet component 300. The inlet component 200, outlet component 300, pretreatment module 400, water quality detection module 500, water flow distribution component 600, biological treatment module 700, sedimentation and filtration module 800, and disinfection module 900 are all electrically connected to an intelligent control system.

[0047] During operation, the inlet component 200 introduces wastewater into the device, which then enters the container 100. The pretreatment module 400 performs preliminary physical treatment on the wastewater. Subsequently, the water flows into the water quality detection module 500 for real-time water quality analysis. Based on the analysis results from the water quality detection module 500, the intelligent control system distributes the water flow accordingly to the biological treatment module 700, the sedimentation and filtration module 800, and the disinfection module 900 via the water flow distribution component 600.

[0048] When a high concentration of organic pollutants is detected in the wastewater, the water can be distributed to the biological treatment module 700 for biochemical degradation through the water distribution component 600, then distributed to the sedimentation and filtration module 800 for solid-liquid separation and deep filtration through the water distribution component 600, and finally distributed to the disinfection module 900 for disinfection and sterilization through the water distribution component 600.

[0049] When the wastewater is detected to be mainly composed of suspended solids and particulate matter, the water flow can be directly distributed to the sedimentation and filtration module 800 through the water flow distribution component 600 for solid-liquid separation and deep filtration, and then distributed to the disinfection module 900 for disinfection and sterilization through the water flow distribution component 600.

[0050] When the wastewater is detected to contain mainly low-concentration impurities, meaning the wastewater quality is close to the discharge standard, it can be directly allocated to the disinfection module 900 for disinfection and sterilization.

[0051] The water, after being disinfected and sterilized by the disinfection module 900, is finally discharged through the water outlet component 300, completing the treatment process.

[0052] Please refer to the above as well. Figures 1 to 9 In one specific embodiment of this application, the water inlet assembly 200 includes a water inlet pipe 201 fixedly installed on the container 100. The water inlet pipe 201 has a first connecting end 202, a second connecting end 203, and a third connecting end 204. The first connecting end 202 and the second connecting end 203 extend to the outside of the container 100. The third connecting end 204 is connected to a first water pump 205. The output end of the first water pump 205 is connected to the input end of the pretreatment module 400. The first water pump 205 is electrically connected to the intelligent control system.

[0053] During operation, the water inlet assembly 200 connects to an external wastewater source via a water inlet pipe 201 extending to the outside of the container 100, through either the first connection end 202 or the second connection end 203. Furthermore, multiple modular containerized wastewater treatment units are connected together to form an array via the first and second connection ends 202 and 203. The intelligent control system can then activate the first water pump 205 according to treatment requirements, drawing wastewater from the water inlet pipe 201 through the third connection end 204 and pumping it from the output end of the first water pump 205 into the pretreatment module 400, thereby completing the introduction and transportation of wastewater.

[0054] Please refer to the above as well. Figures 1 to 9 In one specific embodiment of this application, the water outlet assembly 300 includes a water outlet pipe 301 fixedly installed on the container 100. The water outlet pipe 301 has a fourth connection end 302, a fifth connection end 303, and a sixth connection end 304. The fourth connection end 302 and the fifth connection end 303 extend to the outside of the container 100. The sixth connection end 304 is connected to a second water pump 305. The input end of the second water pump 305 is connected to the output end of the disinfection module 900. The second water pump 305 is electrically connected to the intelligent control system.

[0055] During operation, the treated clean water, after meeting the standards, is output from the disinfection module 900 and enters the outlet pipe 301 under the control of the second water pump 305. The intelligent control system can instruct the second water pump 305 to start, allowing water to flow in from the sixth connection end 304 and finally be discharged from the fourth connection end 302 or the fifth connection end 303 extending outside the casing. The design of the fourth connection end 302 and the fifth connection end 303 allows a single device to discharge independently, or it can be connected in series with the inlet pipes 201 of other similar devices to form a modular parallel or series treatment array, flexibly adapting to the needs of different treatment scales.

[0056] Please refer to the above as well. Figures 1 to 9 In one specific embodiment of this application, the pretreatment module 400 includes a pretreatment box 401. A pretreatment box cover 402 is fixedly and sealed to the top of the pretreatment box 401. A pretreatment water inlet pipe 403 is fixedly and sealed to the pretreatment box cover 402. The pretreatment water inlet pipe 403 is connected to the output end of the first water pump 205 in the water inlet assembly 200. A pretreatment water outlet pipe 404 is fixedly and sealed to the bottom of the pretreatment box 401. The pretreatment water outlet pipe 404 is connected to the input end of the water quality detection module 500. Three sets of drawer-type filter assemblies 405 are sealed and slidably connected between the pretreatment water inlet pipe 403 and the pretreatment water outlet pipe 403 on the pretreatment box 401. A pressure sensor 406 is fixedly and sealed to the pretreatment box cover 402. The pressure sensor 406 is electrically connected to the intelligent control system.

[0057] During operation, wastewater enters the pretreatment tank 401 through the pretreatment inlet pipe 403. The water flows downwards through multiple drawer-type filter components 405, which intercept large suspended solids and particulate matter in the wastewater. The trapped impurities settle within the drawer-type filter components 405. A pressure sensor 406 monitors the water pressure inside the tank in real time. When the drawer-type filter components 405 gradually become clogged, increasing water flow resistance and raising the pressure inside the pretreatment tank 401 to a set threshold, the intelligent control system issues an alarm, prompting the need to clean or replace the filter components. By employing a design with three sets of drawer-type filter components 405, cleaning or replacing the filter components can be performed alternately, eliminating the need for system downtime and ensuring operational efficiency. The pretreated wastewater flows into the water quality detection module 500 through the pretreatment outlet pipe 404 at the bottom.

[0058] Please refer to the above as well. Figures 1 to 9In one specific embodiment of this application, the drawer-type filter assembly 405 includes a drawer body 4051. A first groove 4052 is provided on the side wall of the pretreatment tank 401 between the pretreatment inlet pipe 403 and the pretreatment outlet pipe 404, corresponding to the drawer body 4051. The drawer body 4051 is slidably connected in the first groove 4052. A filter screen 4053 is detachably installed on the bottom surface of the drawer body 4051. A filter residue collection chamber 4054 is provided on the bottom surface of the drawer body 4051 above the filter screen 4053. A second groove 4055 penetrating the inner end of the drawer body 4051 is provided inside the drawer body 4051. The inner sliding connection of the second slide groove 4055 is sealed with a sealing plate 4056. The top surface of the drawer body 4051 has several equidistantly arranged first water passage holes 4057, which are connected to the filter cake collection chamber 4054. The sealing plate 4056 has second water passage holes 4058 corresponding to the first water passage holes 4057. A spring 4059 is fixedly connected between the inner end of the sealing plate 4056 and the inner end of the second slide groove 4055. When the spring 4059 is not subjected to external force, it pushes the sealing plate 4056 to slide so that the first water passage holes 4057 and the second water passage holes 4058 are misaligned to form a seal.

[0059] During operation, when the drawer body 4051 is fully pushed into the pretreatment box 401, its inner end contacts the internal structure of the box and presses against the sealing plate 4056, overcoming the elastic force of the spring 4059. This causes the sealing plate 4056 to slide towards the inner end of the second slide groove 4055, aligning the first water passage hole 4057 with the second water passage hole 4058, allowing water to flow into the filter cake collection chamber 4054 inside the drawer body 4051 and through the filter screen 4053. When cleaning is required, such as... Figure 5 As shown in the second drawer-type filter assembly 405, after the drawer body 4051 is pulled outward, the spring 4059 pushes the sealing plate 4056 to reset, so that the first water passage hole 4057 and the second water passage hole 4058 are misaligned and sealed, effectively preventing wastewater leakage in the box during the drawer being pulled out, and realizing safe and convenient maintenance operations.

[0060] Please refer to the above as well. Figures 1 to 9 In one specific embodiment of this application, the water quality detection module 500 includes a water quality detection box 501, a water quality detection box cover 502 fixedly and sealed to the top of the water quality detection box 501, a water quality detection input port 503 on the water quality detection box cover 502, a water quality detection output port 504 on the side wall of the water quality detection box 501 near its bottom, and the water quality detection output port 504 is connected to the water flow distribution component 600; a water quality detection sensor 505 is fixedly and sealed to the water quality detection box cover 502, and the water quality detection sensor 505 is electrically connected to the intelligent control system.

[0061] During operation, pretreated wastewater enters the water quality monitoring tank 501 through the water quality monitoring inlet 503. A water quality sensor 505, fixedly mounted on the tank cover, performs real-time online monitoring of the water and transmits the water quality parameter data to the intelligent control system. The intelligent control system uses this data to determine the main pollution characteristics of the wastewater, providing a basis for subsequent water flow allocation decisions. The water that has completed the monitoring flows out from the water quality monitoring outlet 504 at the bottom and enters the water flow allocation component 600.

[0062] It is understood that, in one specific embodiment of this application, the water quality detection sensor 505 may include, but is not limited to, a pH sensor, a COD sensor, a turbidity sensor, an ammonia nitrogen sensor, etc.

[0063] Please refer to the above as well. Figures 1 to 9 In one specific embodiment of this application, the water distribution component 600 includes a water distribution main pipe 601, which is sealed to the water quality detection output port 504 in the water quality detection module 500. A first branch pipe 602, a second branch pipe 603, and a third branch pipe 604 are respectively fixedly and sealed to the biological treatment module 700, the sedimentation and filtration module 800, and the disinfection module 900 on the water distribution main pipe 601. A first electric pump 605 is installed on the first branch pipe 602, a second electric pump 606 is installed on the second branch pipe 603, and a third electric pump 607 is installed on the third branch pipe 604. The output end of the first electric pump 605 is connected to the input end of the biological treatment module 700; the output end of the second electric pump 606 is connected to the input end of the third electric pump 607. A three-way pipe 608 is used, with its other two ends connected to a fourth electric pump 609 and a fifth electric pump 610, respectively. The fourth electric pump 609 is connected to the output end of the biological treatment module 700, and the fifth electric pump 610 is connected to the input end of the sedimentation and filtration module 800. The output end of the third electric pump 607 is connected to a second three-way pipe 611, one end of which is connected to a sixth electric pump 612, which is connected to the output end of the sedimentation and filtration module 800. The other end of the second three-way pipe 611 is connected to the input end of the disinfection module 900. The first electric pump 605, the second electric pump 606, the third electric pump 607, the fourth electric pump 609, the fifth electric pump 610, and the sixth electric pump 612 are electrically connected to the intelligent control system.

[0064] During operation, the intelligent control system controls the start-stop combinations of the first electric pump 605, the second electric pump 606, the third electric pump 607, the fourth electric pump 609, the fifth electric pump 610, and the sixth electric pump 612 based on the real-time data from the water quality detection module 500, thereby planning the water flow path.

[0065] Taking the treatment of highly organic polluted wastewater as an example, the first electric pump 605 is first turned on, and the other pumps are turned off, allowing the water to enter the biological treatment module 700. After biochemical treatment, the fourth electric pump 609 and the fifth electric pump 610 are then turned on, and the other pumps are turned off, allowing the water to flow through the first three-way pipe 608 into the sedimentation and filtration module 800. After sedimentation and filtration, the sixth electric pump 612 is then turned on, and the other pumps are turned off, allowing the water to flow through the second three-way pipe 611 into the disinfection module 900. This design achieves intelligent and flexible switching of the treatment process.

[0066] In one specific embodiment of this application, the first electric pump 605, the second electric pump 606, the third electric pump 607, the fourth electric pump 609, the fifth electric pump 610, and the sixth electric pump 612 are all connected in series with an electrically controlled valve that is electrically connected to the intelligent control system.

[0067] During operation, the electrically controlled valves and the electric pump connected in series with them are synchronously and coordinated by the intelligent control system to open and close.

[0068] When a certain path needs to be opened, the intelligent control system first issues a command to open the corresponding electrically controlled valve. After the valve is fully opened, the corresponding electric pump is started to ensure that the pump starts under low load and prevents pump stalling or overload.

[0069] When it is necessary to close the path, first stop the operation of the electric pump. After the pump has completely stopped, close the corresponding electrically controlled valve. This can effectively utilize the valve's forced sealing function to completely cut off the water flow and prevent backflow of the medium, system pressure fluctuations, or water hammer that may occur after the pump stops.

[0070] This not only protects the pump body itself and extends the service life of the equipment, but also provides double safety for the entire water distribution system through the reliable shut-off of the electrically controlled valves. This ensures the isolation reliability of each treatment module during switching, standby, or maintenance, and improves the stability and automation level of the entire wastewater treatment device.

[0071] Please refer to the above as well. Figures 1 to 9In one specific embodiment of this application, the biological treatment module 700 includes a biological treatment tank 701, a biological treatment tank cover 702 installed on the top of the biological treatment tank 701, and an aeration device 703 installed at the bottom of the biological treatment tank 701, which is electrically connected to the intelligent control system; a biological treatment inlet 704 is provided on the outer side of the biological treatment tank 701 near its top, a biological treatment outlet 705 is provided on the outer side of the biological treatment tank 701 near its bottom, and a biological treatment maintenance port 706 is provided on the outer side of the biological treatment tank 701 near its middle; the biological treatment inlet 704 is connected to the output end of the first electric pump 605 in the water flow distribution assembly 600, and the biological treatment outlet 705 is connected to the input end of the fourth electric pump 609 in the water flow distribution assembly 600; a maintenance cover 707 is detachably and sealingly connected to the biological treatment maintenance port 706.

[0072] During operation, the wastewater to be treated enters the biological treatment tank 701 through the biological treatment inlet 704. The intelligent control system activates the aeration device 703 to continuously oxygenate the tank, providing the necessary conditions for the metabolic activities of aerobic microorganisms. The microorganisms decompose and transform the organic pollutants in the wastewater as a nutrient source. The treated mixture flows out through the biological treatment outlet 705. The biological treatment maintenance port 706 and its maintenance cover 707 facilitate the periodic addition of microbial agents and the maintenance or replacement of the aeration device 703.

[0073] Please refer to the above as well. Figures 1 to 9 In one specific embodiment of this application, the aeration device 703 can be a high-efficiency aeration device such as a disc or tubular microporous aerator, a jet aerator, or a swirl aerator.

[0074] During operation, the aeration device 703 operates according to the instructions of the intelligent control system. By releasing microbubbles, it increases the gas-liquid contact area, efficiently transfers oxygen, and plays a stirring role to maintain the suspension of sludge, creating a stable hydraulic and biochemical environment for the biodegradation process.

[0075] Please refer to the above as well. Figures 1 to 9 In one specific embodiment of this application, the sedimentation filtration module 800 includes a sedimentation filtration box 801. A sedimentation filtration input pipe 802 is fixedly and sealed to the outside of the sedimentation filtration box 801 near its top. A sedimentation filtration output pipe 803 is fixedly and sealed to the outside of the sedimentation filtration box 801 near its middle part. A slag discharge device 804 is fixedly and sealed to the bottom of the sedimentation filtration box 801. A filtration device 805 is installed inside the sedimentation filtration box 801 below the sedimentation filtration input pipe 802. A sedimentation chamber 806 communicating with the slag discharge device 804 is provided below the filtration device 805. The slag discharge device 804 is electrically connected to the intelligent control system.

[0076] During operation, the water to be treated enters the sedimentation and filtration tank 801 through the sedimentation and filtration inlet pipe 802. It first undergoes deep filtration through the filtration device 805, trapping fine suspended solids. Subsequently, the water flow slows down, and under gravity, heavier suspended particles further settle and separate in the sedimentation chamber 806. Accumulated sludge is periodically discharged through the bottom sludge discharge device 804, and the supernatant flows out through the sedimentation and filtration outlet pipe 803.

[0077] It is understood that in some specific embodiments of this application, the slag discharge device 804 may be equipped with a sludge collection hopper, which is connected to the sedimentation chamber 806 through a sludge discharge pipe, and a sludge discharge valve controlled by an intelligent control system is installed on the sludge discharge pipe.

[0078] During operation, when the sludge in the sedimentation chamber 806 accumulates to a certain amount, the intelligent control system issues a command to open the sludge discharge valve, and the concentrated sludge is discharged from the device under gravity or with a small amount of hydraulic assistance. After the sludge discharge is completed, the valve automatically closes to maintain the continuous operation of the system.

[0079] It is understood that in some specific embodiments of this application, the filtration device 805 includes a support frame, in which filter media layers of different particle sizes are filled from top to bottom. The filter media layers can be made of materials such as quartz sand, activated carbon, or ceramic filter media. Hollow fiber membranes, flat sheet membranes, or other membrane modules can also be installed on the support frame.

[0080] During operation, water flows through the filter media layer or membrane surface, and suspended solids, colloids, etc. are physically intercepted or adsorbed, achieving deep purification and clarification of water.

[0081] Please refer to the above as well. Figures 1 to 9 In one specific embodiment of this application, the disinfection module 900 includes a disinfection tank 901. A tank cover 902 is fixedly and sealed to the top of the disinfection tank 901. A disinfection input port 903 is provided on the tank cover 902. The disinfection input port 903 is sealed to the second three-way pipe 611 in the water flow distribution component 600. A disinfection output port 904 is provided at the bottom of the disinfection tank 901. The disinfection output port 904 is sealed to the input end of the second water pump 305 in the water outlet component 300. An ultraviolet disinfection device 905 is installed inside the disinfection tank 901. The ultraviolet disinfection device 905 is electrically connected to the intelligent control system.

[0082] During operation, the treated water enters the disinfection tank 901 through the disinfection inlet 903. The intelligent control system activates the ultraviolet disinfection device 905, which generates short-wave ultraviolet light to irradiate the flowing water. The UVC band of the short-wave ultraviolet lamp destroys the DNA / RNA structure of pathogenic microorganisms such as bacteria and viruses in the water, rendering them unable to reproduce, thus achieving disinfection and sterilization. The disinfected water flows out through the disinfection outlet 904, ready for discharge.

[0083] It is understood that, in some specific embodiments of this application, the ultraviolet disinfection device 905 may employ an ultraviolet lamp assembly, a ballast, and an intensity sensor sealed within a quartz sleeve.

[0084] During operation, the ultraviolet lamps are illuminated, and the water flows within the disinfection tank 901 along a specific flow channel design to ensure full exposure to the ultraviolet radiation field. An intensity sensor monitors the ultraviolet output intensity in real time and feeds the signal back to the intelligent control system to ensure the stability of the disinfection effect, and prompts maintenance or lamp replacement when the intensity is insufficient.

[0085] Please refer to the above as well. Figures 1 to 9 In one specific embodiment of this application, the intelligent control system includes a PLC controller, which is connected to a signal transceiver module, and the signal transceiver module is connected to a mobile terminal. The PLC controller is electrically connected to the first water pump 205 in the water inlet assembly 200, the second water pump 305 in the water outlet assembly 300, the pressure sensor 406 in the pretreatment module 400, the water quality sensor 505 in the water quality detection module 500, the first electric pump 605, the second electric pump 606, the third electric pump 607, the fourth electric pump 609, the fifth electric pump 610, and the sixth electric pump 612 in the water flow distribution assembly 600, the aeration device 703 in the biological treatment module 700, the sludge discharge device 804 in the sedimentation and filtration module 800, and the ultraviolet disinfection device in the disinfection module 900.

[0086] During operation, the PLC controller acts as the control core, receiving real-time signals from pressure sensor 406, water quality sensor 505, and other sensors. Based on a preset program and remote commands received from the mobile terminal via the signal transceiver module, the PLC controller coordinates the start and stop of the first water pump 205, the start and stop combinations of various electric pumps, the operating intensity of the aeration device 703, the sludge discharge cycle of the sludge discharge device 804, and the start, stop, and intensity of the ultraviolet disinfection device 905. This achieves fully automated, intelligent operation and remote monitoring of the entire process from water intake, pretreatment, detection, diversion treatment, disinfection to drainage.

[0087] The implementation principle of a modular containerized wastewater treatment device according to an embodiment of this application is as follows: This application achieves modularity, compactness, and mobility of wastewater treatment equipment by highly integrating pretreatment, water quality testing, intelligent diversion, biological treatment, sedimentation filtration, and disinfection units into a standard container. The core technology utilizes real-time feedback from the water quality testing module 500, with an intelligent control system dynamically controlling the start and stop of each electric pump in the water flow distribution component 600. This allows wastewater to select the most direct and efficient treatment path based on its actual water quality, achieving quality-based diversion and precise treatment. This avoids the energy and time waste associated with traditional processes that treat all wastewater in a single setup.

[0088] The sealed sliding structure of the drawer-type filter assembly 405, in conjunction with the pressure sensor 406, enables non-stop maintenance and safe operation of the pretreatment unit. Furthermore, the various functional modules are connected to pumps and valves via standardized pipelines, and are centrally automated and remotely monitored by a unified intelligent control system. This makes the entire system not only flexible and adaptable in its processing flow, but also convenient to install and simple to maintain.

[0089] The design of this application is particularly suitable for scenarios such as distributed sewage treatment, emergency treatment, temporary construction camps and small and medium-sized parks. It can be quickly deployed and the number of modules can be flexibly expanded according to treatment needs, effectively solving the pain points of traditional sewage treatment facilities such as long construction cycle, large land area and insufficient flexibility.

[0090] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
