[0038] To make the objectives, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work shall fall within the scope of protection of the present invention.

[0039] To facilitate understanding of this embodiment, the following is a brief introduction to the technical terms used in this application.

[0040] Sludge-based filler refers to filler made from sludge as the main raw material, which can provide a surface for microorganisms to attach and grow, thereby enhancing the efficiency of sewage treatment.

[0041] Enhanced biofill is a specially designed filler containing substances that promote microbial growth and is used to increase the activity and quantity of microorganisms in sewage treatment wetland systems.

[0042] Wetland treatment wetland system is an artificial wetland system that imitates the function of natural wetlands. It is used to treat sewage and uses the combined effects of plants, microorganisms and soil in the wetland to remove pollutants in the water.

[0043] A drum wetland is a wastewater treatment technology that simulates natural wetlands. It uses one or more rotating drums filled with media such as stone, sand, or specialized fillers, which are inhabited by aquatic plants and microorganisms. As wastewater flows through the drums, it is purified through physical, chemical, and biological processes. This device is commonly used in municipal and agricultural wastewater treatment and is popular for its small footprint and low operating costs.

[0044] After introducing the technical terms involved in this application, the application scenarios and design concepts of the embodiments of this application are briefly introduced.

[0045] Existing artificial wetland treatment systems are prone to problems such as packing layer clogging, which seriously affects the treatment efficiency and operational stability of the wetland system.

[0046] Based on this, an embodiment of the present application provides an intelligently controlled modular anti-clogging wetland treatment wetland system reinforced with sludge-based fillers.

[0047] Example 1

[0048] The present application provides a first aspect, and an embodiment of the present invention provides that the present application provides an intelligent control modular anti-clogging wetland treatment wetland system reinforced with sludge-based fillers, the wetland system comprising: a sludge-based wetland system 1, a reinforced wetland system and an intelligent control wetland system.

[0049] The sludge-based wetland system 1 and the enhanced wetland system are respectively connected to the intelligent control wetland system, and the intelligent control wetland system controls the enhanced wetland system to add enhanced biological fillers to the sludge-based wetland system.

[0050] Among them, combined Figure 1 As shown, the sludge-based wetland system 1 includes an upper drum-type wetland 2 and a lower filler wetland 3. The upper drum-type wetland 2 comprises a drum 21 and at least two separate wetland areas within the drum 21, at least one of which is filled with sludge-based lightweight filler. A slope is provided at the bottom of the upper drum-type wetland 2 (not shown); the lower filler wetland 3 is filled with conventional filler. As will be appreciated, a drain outlet 11 is also provided at the bottom of the sludge-based wetland system 1, which is opened to discharge accumulated waste.

[0051] The present application provides a wetland system for treating sewage, which uses sludge as a base material. It consists of a two-layer structure, the upper layer is a drum-type wetland 2, and the lower layer is a filler wetland 3. The drum-type wetland 2 is composed of a large drum 21, which is arranged at the water inlet end of the wetland system to form an independent water tank. The axis of the drum 21 is fixed on the inner side of the wetland wall on both sides. A bearing seat can be used to support the drum. The material of the bearing seat should be corrosion-resistant. The drum 21 rotates by itself depending on the flow of incoming water. At this time, the small blades arranged at intervals on the drum 21 can enhance the rotation effect when the water flows through. These blades can increase the chance of collision with suspended particulate matter and sludge fillers, and promote sedimentation. Furthermore, if the water flow is not sufficient to drive the drum 21, a small motor or other power device can be used to drive the drum to ensure that the drum 21 can work normally under low flow and low flow rate conditions. Water enters from the left and flows through the drum area. As the water flows through, the suspended particles collide with the blades and sludge fillers on the drum 21 and gradually settle to the lower filler wetland 3. A partition with a through hole extending obliquely downward is provided in the lower filler wetland 3. The upper settled material enters the lower area through the through hole. When the amount of sediment accumulates to a set time or a set accumulation amount, the drain port can be opened to discharge the sediment, reducing the particulate pollutants entering the rear-end wetland system and facilitating anti-clogging. In this embodiment, the water inlet of the drum 21 is configured as a sawtooth weir to evenly distribute the inlet flow and ensure that the water flows smoothly and evenly into the drum 21. The water outlet below is configured as a rectangular trough body to facilitate the collection of treated clean water and guide it to the subsequent wetland system. A plurality of through holes are provided at intervals throughout the drum 21, and the interior of the drum 21 is divided into a plurality of areas, including a sludge-based filler wetland area 22 filled with a lightweight filler based on sludge and a traditional filler wetland area 23 filled with a traditional filler, combined with Figure 2 The figure shows an exemplary structure of a drum-type wetland 2, which includes a sludge-based filler wetland area 22 and two conventional filler wetland areas 23. The number of separate wetland areas can be set arbitrarily, and the order of arrangement can be changed as needed, without limitation. Sludge-based lightweight fillers promote microbial growth, thereby improving sewage treatment efficiency. The bottom of the upper drum-type wetland 2 is designed with a slope to help reduce rolling resistance and facilitate water flow. The lower filler wetland 3 is filled with conventional fillers, further enhancing sewage treatment capacity. Modular design and intelligent control technology are further combined to improve wetland sewage treatment efficiency and prevent clogging.

[0052] Among them, traditional fillers can be divided into the following categories according to their material and structural characteristics: natural fillers, synthetic fillers, and combined fillers. Among them, natural fillers include: boulders, volcanic rocks, and expanded clay; synthetic fillers include: plastic fillers (such as polyethylene PE, polypropylene PP), fiber fillers (such as polyester fiber, glass fiber); combined fillers are fillers obtained by combining natural fillers and synthetic fillers (such as the combination of expanded clay and plastic mesh). The above are only examples and are not limited here.

[0053] In this embodiment, the intelligently controlled modular anti-clogging wetland treatment system with sludge-based fillers is primarily composed of three components: a sludge-based wetland system 1, a reinforced wetland system, and an intelligently controlled wetland system. The reinforced wetland system adds reinforced biological fillers to the sludge-based wetland system 1. These fillers promote the growth and reproduction of more beneficial microorganisms, thereby improving the wetland's treatment effectiveness. The intelligently controlled wetland system is the brain of the entire wetland system, responsible for monitoring the entire treatment process and intelligently controlling the reinforced wetland system to add an appropriate amount of reinforced biological fillers to the sludge-based wetland system, ensuring efficient and stable operation of the wetland system.

[0054] In combination with the first aspect, the area ratio of the lower filler wetland 3 to the upper drum-type wetland 2 is 1:1 to 3:1.

[0055] In this embodiment, the area ratio of the lower filler wetland 3 to the upper drum-type wetland 2 is set in the range of 1:1 to 3:1. This means that when designing the composite wetland system, the floor area of ​​the upper drum-type wetland 2 can be kept equal to the floor area of ​​the lower filler wetland 3, or the area of ​​the lower filler wetland 3 can be three times the area of ​​the upper drum-type wetland 2. This ratio configuration is intended to optimize the treatment efficiency and function of the wetland, ensuring that the best ecological purification effect can be achieved in different application scenarios. By flexibly adjusting the area ratio of the two, the treatment requirements of different water qualities and flow rates can be effectively responded to, thereby improving the overall operating performance and stability of the wetland.

[0056] Among them, the upper drum-type wetland 2 is driven by a power source to roll, and the incoming sewage flow is distributed by rotation or stirring. After preliminary purification based on the internal sludge-based filler wetland area 22 and traditional filler wetland area 23, the water flows into the lower filler wetland 3 under the action of gravity and is further purified under the action of traditional filler.

[0057] In combination with the first aspect, the slope angle is 30°-60°.

[0058] The bottom of the Upper Drum Wetland 2 features a slope to ensure smooth water flow. The slope is precisely set between 30° and 60°. This angle not only improves the wetland's purification efficiency but also effectively prevents sediment accumulation, thereby maintaining the wetland's long-term stable operation. A deep understanding and ingenious application of natural water flow patterns contribute to the Upper Drum Wetland 2's exceptional performance in water quality treatment.

[0059] In combination with the first aspect, the drum 21 has a diameter of 2 m and a length of 4 m.

[0060] The larger diameter and length of the upper drum wetland 2 provide ample space to accommodate more fillers and microorganisms, enhancing pollutant treatment capabilities. Furthermore, the longer length extends the water flow path, increasing the contact time between water and fillers and further improving purification effectiveness. This not only improves structural stability but also adapts to installation requirements in diverse site conditions.

[0061] In combination with the first aspect, the sludge-based wetland system further includes:

[0062] A three-dimensional water distribution pipe (not shown in the figure) is provided at the water inlet of the wetland system, and the three-dimensional water distribution pipe includes a plurality of water distribution pipes extending from the first to the third directions and intersecting and penetrating;

[0063] Among them, the first to third directions are perpendicular to each other.

[0064] Three-dimensional water distribution pipes feature a multi-directional, intersecting structure. Specifically, the pipes extend in three mutually perpendicular directions (the first, second, and third directions) and intersect. The pipes in different directions connect at their intersections, forming a three-dimensional network of water flow paths. This evenly distributes incoming water throughout the wetland or treatment system, preventing areas of excessive or insufficient flow. This uniform flow distribution helps improve the contact efficiency between pollutants and the filler surface, thereby enhancing overall purification performance. It also reduces the likelihood of blockage in a single pipe; even if a blockage occurs in one section, flow remains unimpeded in other paths.

[0065] As you can understand, this three-dimensional water distribution pipe is suitable for treatment units of various shapes and sizes, and the length and spacing of the water distribution pipe can be adjusted according to specific needs. Applying the three-dimensional water distribution pipe to the water inlet of the sludge-based wetland system 1 effectively guides the water flow, evenly distributing it across all cross-sections of the drum 21, ensuring that every point participates in the purification process. Combined with the 30° to 60° slope design of the bottom, the three-dimensional water distribution pipe allows water to flow more smoothly through the packing layer, increasing the contact time between water and packing, thereby significantly improving purification efficiency. During this process, the uniform water flow distribution helps reduce the formation of localized sediments, further maintaining the long-term stable operation of the wetland.

[0066] It can be understood that the first to third directions are perpendicular to each other and correspond to the X-axis, Y-axis and Z-axis in the geodetic coordinate system.

[0067] In combination with the first aspect, the intelligent wetland control system includes: a monitoring component and a control unit.

[0068] Monitoring components include water quality sensors, flow sensors and liquid level sensors located at designated locations in the sludge-based wetland system.

[0069] The control unit is connected to the monitoring component and is used to receive the monitoring data sent by the monitoring component and perform data analysis and processing to automatically adjust the sludge-based wetland system; the control unit is also electrically connected to the delivery valve (not shown in the figure), which is arranged on the connecting pipeline between the enhanced wetland system and the sludge-based wetland system 1. The delivery valve is opened or closed to conduct or block the pipeline.

[0070] As you can see, the intelligent wetland system consists of two main parts: the monitoring component and the control unit. These two parts work together to ensure the efficient operation and automatic adjustment of the wetland system.

[0071] The system is responsible for collecting various parameter data of the wetland system in real time. Parameter data includes various water quality indicators at designated locations, the flow rate of water in and out of the inlet and outlet pipes, and the water level in specific areas of the wetland system.

[0072] The control unit is used to receive data from the monitoring components, analyze the collected data according to preset algorithms and models, determine the current operating status of the wetland system, and ultimately achieve automated regulation of the wetland system.

[0073] As you can understand, water quality indicators typically include at least key parameters such as pH, dissolved oxygen (DO), chemical oxygen demand (COD), and ammonia nitrogen (NH3-N). By monitoring water quality changes in real time, abnormalities can be detected and reported promptly, providing a basis for subsequent treatment. When the water quality sensor detects that the water quality exceeds the standard, the control unit can activate the dosing device or adjust the aeration intensity to improve the water quality.

[0074] Similarly, the flow rate of the inlet and outlet water installed at the inlet pipe or outlet pipe is collected, and the opening of the inlet valve or pump is automatically adjusted to maintain the set flow range, ensure the stability of the water volume, and prevent overload or shortage, which will affect the treatment effect.

[0075] Similarly, the water level in a specific area of ​​the wetland system is monitored, and the pump is automatically started and stopped or the drainage valve is adjusted to maintain a reasonable water level, so as to ensure that the water level is within a reasonable range and to avoid overflow due to excessive water level or low water level affecting treatment efficiency.

[0076] In this way, the intelligent wetland control system, by integrating advanced monitoring components and intelligent control units, achieves comprehensive and refined management of sludge-based wetland systems. This system not only improves wastewater treatment efficiency but also significantly reduces operating costs and maintenance, providing reliable technical support for environmental protection projects.

[0077] In the second aspect, the present application provides a control method for a wetland system, which is applied to the control unit of the wetland system, combined with Figure 3 As shown, the method includes:

[0078] S110, obtaining current water quality parameters and target water quality parameters at the outlet of the sludge-based wetland system.

[0079] S120: Generate a control instruction based on the current water quality parameters and the target water quality parameters.

[0080] S130: Adjust the water inlet position, water distribution method and drum speed according to the control instructions.

[0081] It can be understood that the control unit in the intelligent wetland system obtains the difference between the current water quality parameters (such as pH value, dissolved oxygen, chemical oxygen demand, etc.) obtained at the water outlet and the preset target water quality parameters, and determines the specific parameters that need to be adjusted, such as the water inlet position, water distribution method and the speed of the drum 21, so as to gradually approach the target water quality, thereby generating corresponding control instructions, and then ensuring that the water quality reaches the expected target based on the realization of intelligent control, and optimizing the operating efficiency of the system.

[0082] In conjunction with the second aspect, the method further includes:

[0083] S140: Obtain the current operating time of the wetland system.

[0084] S150, determining whether the current running time is an integer multiple of the preset delivery time.

[0085] If so, execute step S160; if not, execute S170.

[0086] S160 controls the opening of the delivery valve to add nutrients and microbial elements to the upper drum wetland.

[0087] S170, controlling the wetland system to maintain current operating parameters.

[0088] It is understandable that during the operation of the wetland system, the operating time is also monitored, and when the current operating time is an integer multiple of the preset delivery time, the delivery valve is controlled to open, so as to periodically add nutrients and microbial elements to the upper drum wetland, so as to regularly replenish the microbial community in the sludge-based wetland system, promote the degradation of pollutants, and maintain the long-term stable operation of the wetland.

[0089] In a third aspect, the present application provides an electronic device, Figure 4 As shown, the electronic device includes a memory 131 and a processor 130. The memory 131 is used to store computer programs, and the processor 130 runs the computer programs to enable the electronic device to perform the above method.

[0090] Further, combined with Figure 4 The electronic device shown further includes a bus 132 and a communication interface 133 , and the processor 130 , the communication interface 133 and the memory 131 are connected via the bus 132 .

[0091] Among them, the memory 131 may include high-speed random access memory (RAM), and may also include non-volatile memory (non-volatile memory), such as at least one disk storage. The communication connection between the wetland system network element and at least one other network element is realized through at least one communication interface 133 (which can be wired or wireless), and the Internet, wide area network, local area network, metropolitan area network, etc. can be used. The bus 132 can be an ISA bus, a PCI bus or an EISA bus, etc. The bus can be divided into an address bus, a data bus, a control bus, etc. For ease of representation, Figure 4 Only one bidirectional arrow is used in the diagram, but this does not mean that there is only one bus or one type of bus.

[0092] The processor 130 may be an integrated circuit chip with signal processing capabilities. During implementation, each step of the above method can be completed by hardware integrated logic circuits in the processor 130 or by software instructions. The processor 130 may be a general-purpose processor, including a central processing unit (CPU), a network processor (NP), etc.; it may also be a digital signal processor (DSP), an application-specific integrated circuit (ASIC), a field-programmable gate array (FPGA), or other programmable logic devices, discrete gate or transistor logic devices, or discrete hardware components. It can implement or execute the various methods, steps, and logic block diagrams disclosed in the embodiments of the present invention. The general-purpose processor may be a microprocessor or any conventional processor. The steps of the method disclosed in conjunction with the embodiments of the present invention can be directly implemented and executed by a hardware decoding processor, or by a combination of hardware and software modules in the decoding processor. The software module can be located in a storage medium well-known in the art, such as random access memory, flash memory, read-only memory, programmable read-only memory, electrically erasable programmable memory, registers, etc. The storage medium is located in memory 131, and processor 130 reads information in memory 131 and, in conjunction with its hardware, completes the steps of the method of the aforementioned embodiment.
