Specific embodiments

[0022] To make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. Apparently, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0023] To facilitate the understanding of this embodiment, the technical terms designed in this application will be briefly introduced below.

[0024] Sludge-based filler refers to a filler made mainly of sludge, which can provide a surface for the attachment and growth of microorganisms and enhance the efficiency of sewage treatment.

[0025] Reinforced biological filler is a specially designed filler containing substances that promote the growth of microorganisms and is used to improve the activity and quantity of microorganisms in a sewage treatment wetland system.

[0026] Wetland treatment wetland system is an artificial wetland system that mimics the functions of natural wetlands and is used to treat sewage. It utilizes the combined effects of plants, microorganisms and soil in the wetland to remove pollutants in the water.

[0027] Roller wetland is a technology for simulating natural wetland to treat sewage. It has one or more rotating rollers filled with media such as stones, sand or special fillers, on which aquatic plants and microorganisms grow. When sewage flows through the rollers, it is purified through physical, chemical and biological actions. This device is usually used in urban sewage treatment or agricultural wastewater treatment and is popular because of its small floor area and low operating cost.

[0028] After introducing the technical terms involved in this application, next, the application scenarios and design concepts of the embodiments of this application will be briefly introduced.

[0029] Existing artificial wetland treatment systems are prone to problems such as clogging of the filler layer, which seriously affects the treatment efficiency and operation stability of the wetland system.

[0030] Based on this, the embodiments of this application provide an intelligent control type modular anti-clogging wetland treatment system strengthened with sludge-based filler.

[0031] Embodiment 1 In the first aspect provided by this application, the embodiments of the present invention provide an intelligent control type modular anti-clogging wetland treatment system strengthened with sludge-based filler. The system includes: sludge-based wetland system 1, reinforced wetland system and intelligent control wetland system.

[0032] 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 wetland system.

[0033] Among them, as Figure 1 shown, the sludge-based wetland system 1 includes an upper drum wetland 2 and a lower filler wetland 3. The upper drum wetland 2 includes a drum 21 and at least two wetland areas separated inside the drum 21, and at least one of the wetland areas is filled with sludge-based lightweight fillers; a slope (not shown in the figure) is provided at the bottom of the upper drum wetland 2; the lower filler wetland 3 is filled with traditional fillers. It can be understood that a sewage outlet 11 is also provided at the bottom of the sludge-based wetland system 1, and the sewage outlet 11 is opened to discharge the accumulated dirt.

[0034] The intelligent control modular anti-blocking wetland treatment system enhanced by the sludge-based filler provided by this application is used to treat sewage. This system uses sludge as the base material and consists of two layers of structures. The upper layer is the drum wetland 2, and the lower layer is the filler wetland 3. The drum 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 shaft of the drum 21 is fixed inside the wetland walls on both sides, and a bearing seat can be used to support the drum. The material of the bearing seat should have corrosion resistance. The drum 21 rotates by itself relying on the flow of the incoming water. At this time, small blades are arranged at intervals on the drum 21, which can enhance the rotation effect when the water flows through. These blades can increase the collision opportunities with suspended particles and sludge fillers and promote precipitation. Further, if the water flow is not sufficient to drive the drum 21, a small motor or other power devices can also be used to drive the drum to ensure that the drum 21 can work normally under low flow and low flow velocity conditions. The 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 precipitate to the lower filler wetland 3. A partition plate with through holes extending obliquely downward is arranged in the lower filler wetland 3. The substances settled in the upper layer enter the lower area through the through holes. When the quantity of the sediment accumulates to the set time or set accumulation amount, the emptying port can be opened to discharge the sediment, reducing the particulate pollutants entering the subsequent wetland system and facilitating anti-blocking. In this embodiment, the water inlet of the drum 21 is set as a sawtooth weir to evenly distribute the incoming water flow and ensure that the water flows smoothly and evenly into the drum 21. The outlet below is set as a rectangular trough to facilitate collecting the treated clear water and guiding it to the subsequent wetland system. A plurality of through holes are arranged at intervals on the whole body of the drum 21, and the inside of the drum 21 is divided into multiple areas, including a sludge-based filler wetland area 22 filled with sludge-based lightweight fillers and a traditional filler wetland area 23 filled with traditional fillers. As Figure 2As shown, the structure of a drum wetland 2 is exemplarily presented. In this drum wetland 2, there is a sludge-based filler wetland area 22 and two traditional filler wetland areas 23. Among them, the number of separated wetland areas can be set arbitrarily, and the arrangement order can also be changed according to requirements, which is not limited here. The sludge-based lightweight filler helps the growth of microorganisms, thereby improving the efficiency of sewage treatment. Moreover, the bottom of the upper drum wetland 2 is designed with a slope, which helps to reduce the rolling resistance and enables the smooth passage of water flow. The lower filler wetland 3 is filled with traditional fillers, further enhancing the sewage treatment capacity. Further, through modular design and intelligent control technology, the efficiency of the wetland in treating sewage is improved, and the problem of blockage is prevented.

[0035] Among them, traditional fillers can be classified into the following categories according to their material and structural characteristics: natural fillers, synthetic fillers, and composite fillers. Among them, natural fillers include: gravel, volcanic rock, and ceramsite. Synthetic fillers include: plastic fillers (such as polyethylene PE, polypropylene PP), and fiber fillers (such as polyester fiber, glass fiber); composite fillers are fillers obtained by combining natural fillers and synthetic fillers (such as the combination of ceramsite and plastic mesh). The above are only examples and are not limited here.

[0036] In this embodiment, the sludge-based filler enhanced intelligent control modular anti-blockage wetland treatment system mainly consists of three parts: the sludge-based wetland system 1, the enhanced wetland system, and the intelligent control wetland system. The role of the enhanced wetland system is to add enhanced biological fillers to the sludge-based wetland system 1, and these fillers can promote the growth and reproduction of more beneficial microorganisms, thereby improving the treatment effect of the wetland. The intelligent control wetland system is the brain of the entire wetland system. It is responsible for monitoring the entire treatment process and intelligently controlling the enhanced wetland system to add an appropriate amount of enhanced biological fillers to the sludge-based wetland system to ensure the efficient and stable operation of the wetland system.

[0037] Combined with the first aspect, the area ratio of the lower filler wetland 3 to the upper drum wetland 2 is 1:1 to 3:1.

[0038] In this embodiment, the area ratio range of the lower filler wetland 3 to the upper drum wetland 2 is set to 1:1 to 3:1. This means that when designing this composite wetland system, the floor area of the upper drum wetland 2 and the floor area of the lower filler wetland 3 can be equal, or the area of the lower filler wetland 3 can reach three times the area of the upper drum wetland 2. Such a ratio configuration aims to optimize the treatment efficiency and function of the wetland, ensuring the best ecological purification effect in different application scenarios. By flexibly adjusting the area ratio of the two, different water quality and flow treatment requirements can be effectively met, thereby improving the overall operation performance and stability of the wetland.

[0039] Among them, the upper-layer drum wetland 2 is driven by a power source to roll, distributes the incoming sewage flow by rotating or stirring, and after preliminary purification based on the sludge-based filler wetland area 22 and the traditional filler wetland area 23 inside, the water flow enters the lower-layer filler wetland 3 under the action of gravity and is further purified under the action of the traditional filler.

[0040] Combined with the first aspect, the slope angle of the slope is 30° - 60°.

[0041] The bottom of the upper-layer drum wetland 2 has a certain slope to ensure the smooth flow of water. The slope angle range of this slope is accurately set between 30° and 60°. Such an angle selection not only helps improve the purification efficiency of the wetland but also effectively prevents sediment accumulation, thus maintaining the long-term stable operation of the wetland. The profound understanding and ingenious application of the natural water flow law make the upper-layer drum wetland 2 perform excellently in water quality treatment.

[0042] Combined with the first aspect, the diameter of the drum 21 is 2m and the length is 4m.

[0043] The upper-layer drum wetland 2 has a relatively large diameter and length, providing enough space to accommodate more fillers and microorganisms, enhancing the treatment ability of pollutants. At the same time, the longer length extends the water flow path, increases the contact time between water and fillers, and further improves the purification effect. In this way, not only the structural stability is improved, but also the installation requirements under different site conditions can be adapted.

[0044] Combined with the first aspect, this sludge-based wetland system further includes: A three-dimensional water distribution pipe (not shown in the figure), arranged at the water inlet of the wetland system. The three-dimensional water distribution pipe includes a plurality of water distribution pipes extending and intersecting and communicating along the first to third directions; Among them, the first to third directions are perpendicular to each other in pairs.

[0045] The three-dimensional water distribution pipe has the structural characteristics of extending in multiple directions and intersecting and communicating. Specifically, the water distribution pipes extend and intersect and communicate along three mutually perpendicular directions (the first, second, and third directions). The water distribution pipes in different directions are connected to each other at the intersection points, forming a three-dimensional water flow path network. In this way, the incoming water can be evenly dispersed to all parts of the entire wetland or treatment system, avoiding too strong or too weak water flow in local areas. And the uniform water flow distribution helps improve the contact efficiency between pollutants and the filler surface, thus enhancing the overall purification performance; it can also reduce the possibility of a single pipe being blocked. Even if a certain part is blocked, the other paths can still ensure the smooth flow of water.

[0046] 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.

[0047] 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.

[0048] In combination with the first aspect, the intelligent wetland control system includes: a monitoring component and a control unit.

[0049] Monitoring components include water quality sensors, flow sensors and liquid level sensors located at designated locations in the sludge-based wetland system.

[0050] 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.

[0051] 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.

[0052] 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.

[0053] 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.

[0054] 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.

[0055] Similarly, the flow rate of the inlet and outlet water installed at the inlet pipe or outlet pipe is collected, and the opening degree of the inlet valve or pump is automatically adjusted to maintain the set flow rate range, ensure the water volume is stable, prevent overload or insufficiency, and thus affect the treatment effect.

[0056] Similarly, the water level height of a specific area of the wetland system is monitored, and the water pump is automatically started and stopped or the drainage valve is adjusted to maintain a reasonable water level height, so as to ensure that the water level is within a reasonable range, avoid overflow caused by too high water level or affect the treatment efficiency due to too low water level.

[0057] In this way, the intelligent control wetland system realizes the all-round and refined management of the sludge-based wetland system 1 by integrating advanced monitoring components and intelligent control units. This system not only improves the sewage treatment effect, but also greatly reduces the operation cost and maintenance difficulty, providing a reliable technical guarantee for environmental protection projects.

[0058] In a second aspect, the present application provides a control method for a wetland treatment system, which is applied to the control unit of the above-mentioned wetland system, and in combination with Figure 3 As shown, the method includes: S110, obtaining the current water quality parameters and target water quality parameters at the outlet of the sludge-based wetland system.

[0059] S120, generating a regulation instruction based on the current water quality parameters and the target water quality parameters.

[0060] S130, adjusting the inlet position, water distribution mode and roller speed according to the regulation instruction.

[0061] It can be understood that the control unit in the intelligent control wetland system determines the specific parameters that need to be adjusted, such as the inlet position, water distribution mode and the rotation speed of the roller 21, based on the difference between the current water quality parameters (such as pH value, dissolved oxygen, chemical oxygen demand, etc.) obtained at the outlet and the preset target water quality parameters, so as to gradually approach the target water quality, thereby generating the corresponding regulation instruction, and further realizing intelligent regulation to ensure that the water quality reaches the expected target and optimize the operation efficiency of the system.

[0062] In combination with the second aspect, the method further includes: S140, obtaining the current operation duration of the wetland system.

[0063] S150, judging whether the current operation duration is an integer multiple of the preset dosing duration.

[0064] If so, execute step S160; if not, execute S170.

[0065] S160, controlling the dosing valve to open to add nutrients and microbial elements to the upper-layer drum-type wetland.

[0066] S170, control the wetland system to operate while maintaining the current operating parameters.

[0067] It can be understood that during the operation of the wetland system, the operation duration is also monitored. When the current operation duration is an integer multiple of the preset dosing duration, the dosing valve is controlled to open to periodically add nutrients and microbial elements to the upper-layer drum wetland, so as to regularly supplement the microbial community in the sludge-based wetland system, promote pollutant degradation, and maintain the long-term stable operation of the wetland.

[0068] In a third aspect, an embodiment of the present application provides an electronic device. As Figure 4 shown, the electronic device includes a memory 131 and a processor 130. The memory 131 is used to store a computer program, and the processor 130 runs the computer program to enable the electronic device to execute the above method.

[0070] Among them, the memory 131 may include a high-speed random access memory (RAM, Random Access Memory), and may also include a non-volatile memory, such as at least one disk memory. Through at least one communication interface 133 (which can be wired or wireless), a communication connection is established between the wetland system network element and at least one other network element. 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, an EISA bus, etc. The bus can be divided into an address bus, a data bus, a control bus, etc. For the sake of representation, Figure 4 only a bidirectional arrow is used in [description], but it does not mean that there is only one bus or one type of bus.

[0071] The processor 130 may be an integrated circuit chip with the ability to process signals. In the implementation process, each step of the above method may be completed by the integrated logic circuit of the hardware in the processor 130 or the instructions in the form of software. The above-mentioned processor 130 may be a general-purpose processor, including a central processing unit (CPU for short), a network processor (NP for short), etc.; it may also be a digital signal processor (DSP for short), an application specific integrated circuit (ASIC for short), a field-programmable gate array (FPGA for short), or other programmable logic devices, discrete gate or transistor logic devices, discrete hardware components.
