[0048] The following describes the embodiments of the present invention by specific examples, and those skilled in the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present invention. It should be noted that the following embodiments and features in the embodiments can be combined with each other without conflict.

[0049] It should be noted that the illustrations provided in the following embodiments are only schematic illustrations of the basic concept of the present invention, and thus the drawings only show components related to the present invention rather than being drawn according to the number, shape and size of components in actual implementation. In actual implementation, the type, quantity and proportion of each component may be changed arbitrarily, and the component layout may also be more complicated.

[0050] The technical solutions in the embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0051] like Figure 1 As shown, in one embodiment, the modular sewage treatment method of the present invention includes steps S11 to S15.

[0052] Step S11, collecting sewage to be treated.

[0053] Specifically, sewage is collected through a pipe network or mobile equipment.

[0054] Step S12: pre-treating the wastewater to be treated.

[0055] Specifically, the pretreatment includes grid filtration, sedimentation tank filtration, sedimentation and flotation treatment filtration, and regulating tank filtration. Sewage pretreatment is the first step in the sewage treatment process. Its purpose is to remove large solids, suspended matter and some organic matter in the sewage, reduce the load of subsequent treatment units, and ensure the normal operation of the entire sewage treatment system.

[0056] Specifically, grid filtration is the first process of sewage pretreatment, and its function is to intercept large solid materials in sewage, such as plastic bags, branches, stones, cloth strips, etc. If these materials are not intercepted, they may block pumping stations and pipelines and damage subsequent treatment equipment. The grid is usually composed of metal bars or plastic bars, and the spacing between the bars is determined according to the size of the solids to be intercepted. Sedimentation tank filtration is a process in which suspended particles in sewage are settled to the bottom by gravity to achieve solid-liquid separation. Sedimentation tanks are usually divided into primary sedimentation tanks and secondary sedimentation tanks. The primary sedimentation tank mainly removes larger particles of suspended matter, while the secondary sedimentation tank is used to further remove smaller suspended matter and part of the activated sludge. Sedimentation and flotation treatment is a pretreatment method that combines sedimentation and flotation technology. Flotation treatment injects tiny bubbles into the sewage, causing suspended particles to adhere to the bubbles, and scum is formed as the bubbles rise to the water surface, thereby achieving solid-liquid separation. This method is particularly suitable for removing suspended matter with a density less than that of water, such as grease and some organic matter. The main function of the regulating tank is to balance the water volume and water quality of sewage and reduce the impact load of subsequent treatment units. The regulating tank can adjust the water temperature, pH value, pollutant concentration, etc. of the sewage to make it more stable, which is conducive to the stable operation of the subsequent treatment process. In the regulating tank, the sewage stays for a certain period of time, so that the suspended matter in the sewage has the opportunity to further settle, and simple aeration can also be performed to improve the dissolved oxygen conditions in the sewage.

[0057] These pretreatment steps can effectively remove most of the suspended solids and some organic matter in the sewage, create good conditions for subsequent biological or chemical treatment, and ensure the efficient operation of the entire sewage treatment system.

[0058] Step S13: configuring the pretreated sewage into a modular artificial wetland unit and starting wetland treatment.

[0059] Configuring the pre-treated sewage into modular constructed wetland units and initiating wetland treatment includes the following steps:

[0060] Determine the design framework of each wetland unit based on the treatment objectives and sewage characteristics of the sewage to be treated;

[0061] Selecting substrate materials and plant configurations for the wetland units based on regional climate and water quality requirements;

[0062] According to industry standards and engineering geological conditions, the waterway path and water distribution control of the wetland unit are planned.

[0063] The design framework includes wetland unit type, wetland unit size, wetland unit structure, and wetland unit combination method.

[0064] Specifically, the modular artificial wetland unit is composed of multiple wetland units with different plant types and matrix materials to achieve flexible and efficient sewage treatment. The modular artificial wetland unit is an innovative sewage treatment technology that optimizes the treatment effect and improves the flexibility and scalability of the system by decomposing the artificial wetland into multiple independent modular units, each of which is equipped with different plant types and matrix materials. The core of the modular artificial wetland unit lies in its "modular" design. Traditional artificial wetlands are usually built in a single large area, while the modular design divides the wetland into several small units, each of which can be operated and maintained independently. This design not only simplifies the construction process, but also enables the wetland system to be quickly adjusted and expanded according to actual needs. For example, a patent obtained by Suzhou Dehua Ecological Environment Technology Co., Ltd. proposes a modular wetland system including an inlet unit, a wetland unit and a control end. The system distributes water to multiple wetland units in sequence through the control end to ensure the filter bed reaction time, thereby achieving efficient treatment. In the modular wetland system, different types of plants and matrix materials are configured in different wetland units. The selection of plants is mainly based on their ability to absorb and metabolize pollutants. Common ones include reeds, cattails, wild rice stems, etc. These plants can form biofilms on their root systems, effectively removing organic matter and nutrients such as nitrogen and phosphorus from the water. The matrix materials usually use sand and gravel of different particle sizes, activated carbon, etc., which further purify sewage through physical filtration and adsorption. The advantages of modular artificial wetland units are significant. It not only improves the flexibility and scalability of the system, but also allows for rapid adjustments based on specific pollution loads and water quality conditions. Since each unit operates independently, overhaul and maintenance are also more convenient, and damage to a single module will not affect the operation of the entire system. In addition, the modular design also significantly reduces the cost of infrastructure construction and is suitable for places with limited resources such as rural and remote areas.

[0065] like Figure 2 As shown, Figure 2Shown is a flow chart of a wetland configuration module in one embodiment. Step S131, design and planning: Determine the treatment capacity and size of the wetland according to the amount and quality of sewage to be treated, as well as the discharge standard. Design the water distribution load, area, water inflow, number of water distributions and single water distribution cycle of a single wetland unit. These parameters determine the treatment capacity and efficiency of the wetland unit. According to the characteristics and treatment requirements of the sewage, select wetland modules of different types and configurations, such as subsurface wetlands, surface flow wetlands, etc., and combine them for layout. Step S132, selection of plants and matrix materials: Select plant species suitable for local climate and sewage treatment requirements, such as reeds, cattails, etc. These plants can form biofilms in the root system, which helps to remove pollutants in the water. Select materials with good filtering and adsorption properties, such as sand and gravel of different particle sizes, activated carbon, etc., to enhance physical filtration and chemical adsorption effects. Step S133, waterway design and water distribution control: Rationally plan the water flow path to ensure that the sewage can be evenly distributed in each wetland unit to maximize the treatment efficiency. Design an effective water distribution system, including water inlet devices and distribution pipes, to ensure uniform flow and adequate contact of sewage in the wetland.

[0066] In one embodiment, in a sewage treatment system applied to rural areas, a wetland system with a treatment capacity of 50 cubic meters per day is designed according to the population of the village and the amount of sewage generated. A combination of subsurface flow wetlands and surface flow wetlands is selected to optimize the efficiency of removing organic matter and nutrients. The water distribution load of a single wetland unit is designed to be 20 liters per square meter per day, the number of water distributions is 3 times a day, and the single water distribution cycle is 8 hours. Reeds and cattails are selected, which are adapted to the local climate and can effectively remove nitrogen and phosphorus from the water. Sand and gravel with a particle size of 5-10 mm are used as the main filter material to improve the filtration efficiency. Design a winding waterway to extend the residence time of water in the wetland and improve the treatment effect. Set up an automatic water inlet device and distribution pipes to ensure that sewage can be evenly distributed to each wetland unit.

[0067] In one embodiment, a wetland system with a treatment capacity of 200 cubic meters per day is designed for wastewater treatment in an industrial park according to the wastewater discharge of the factory. A combination of subsurface wetlands and biological ponds is used to efficiently remove organic matter and heavy metals in industrial wastewater. The water distribution load of a single wetland unit is designed to be 100 liters per square meter per day, the number of water distributions is 4 times a day, and the single water distribution cycle is 6 hours. Plants that can tolerate harmful substances in industrial wastewater, such as calamus and black schizonepeta, are selected. Materials with good adsorption properties, such as modified zeolite and shale, are used to enhance the removal effect of heavy metals. Multi-stage wetland units are designed in series to ensure that the wastewater is fully treated in each unit. An automated control system is installed to adjust the water distribution volume and frequency in real time according to the wastewater discharge situation to ensure the stability of the treatment effect.

[0068] Furthermore, the planning of the waterway path and water distribution control of the wetland unit includes the following steps:

[0069] Design the water inlet unit, water distribution module and water collection module to ensure that the sewage to be treated can evenly enter the wetland unit and be transported through the pump station;

[0070] Real-time monitoring of wastewater to be treated, as well as liquid level control, water quality index adjustment and time control.

[0071] Specifically, the design of the water inlet unit: the water inlet is designed to be able to stably introduce sewage, usually using an overflow or submerged inlet to prevent the impact of water flow from interfering with the wetland matrix. The water inlet pipeline is reasonably laid out to reduce flow resistance and energy loss. Pipeline materials should be corrosion-resistant and aging-resistant, such as HDPE (high-density polyethylene) pipes. By installing flow meters and regulating valves, the water inlet flow rate is accurately controlled to ensure that the hydraulic load of each wetland unit meets the design requirements.

[0072] Water distribution module design: The function of the water distribution channel is to evenly distribute the incoming water to the wetland units. The water distribution channel is designed to be porous or slit-type to ensure uniform distribution of water flow. Depending on the type and size of the wetland, different types of water distribution devices can be selected, such as horizontal water distributors, vertical water distributors or multi-level water distribution systems. The water distribution rate should be adjusted according to the treatment capacity of the wetland and the characteristics of the sewage to ensure sufficient degradation and purification of the sewage in the wetland.

[0073] Water collection module design: A water collection area is set up at the outlet of the wetland unit to collect the treated sewage. The water collection area should be designed to ensure a gentle flow of water to avoid re-contamination of the treated water. The outlet pipe should be designed to prevent backflow and blockage, such as using check valves and grilles. Depending on the type of wetland, surface flow water collection or subsurface flow water collection can be selected to maximize the treatment effect.

[0074] Real-time monitoring and water distribution control: Install liquid level sensors in the water inlet unit and water distribution module to monitor water level changes in real time, and adjust the water inlet valve and water distribution rate through the automatic control system. Use online water quality monitoring instruments, such as pH meters and dissolved oxygen meters, to monitor key water quality indicators of sewage in real time, and automatically adjust related parameters according to set values. Use timers or automated programs to control water distribution operations according to preset time periods to meet sewage treatment needs in different time periods.

[0075] In summary, the water inlet unit, water distribution module, water collection module and real-time monitoring system together constitute a complete solution for the water path and water distribution control of the wetland unit. The implementation of these steps will ensure that sewage can enter the wetland unit evenly and efficiently and be transported through the pump station. At the same time, the introduction of real-time monitoring and automatic control systems further improves the operating stability and treatment effect of the wetland system.

[0076] like Figure 3 As shown, Figure 3 It is a schematic diagram of the structure of wetland treatment, wherein the wetland treatment includes primary wetland treatment and secondary wetland treatment;

[0077] The primary wetland treatment achieves preliminary purification of the wastewater to be treated based on the matrix material and plant configuration of the wetland unit;

[0078] The secondary wetland treatment achieves further purification of the wastewater to be treated based on the biochemical reaction of the wetland unit.

[0079] Primary wetland treatment and secondary wetland treatment are two important purification stages in the artificial wetland sewage treatment system. They jointly achieve efficient purification of sewage through different treatment mechanisms.

[0080] Specifically, primary wetland treatment mainly relies on the matrix materials and plant configuration of the wetland unit, and achieves preliminary purification of sewage through physical filtration and biodegradation processes. Physical filtration: Matrix materials such as sand and gravel, activated carbon, etc. intercept suspended matter and particulate matter in sewage through their surface and internal pores, reducing the concentration of pollutants. Biodegradation: The roots of wetland plants such as reeds and cattails form biofilms, on which microorganisms attach and decompose organic matter in sewage, converting it into harmless substances. Plant absorption: Plants absorb nutrients such as nitrogen and phosphorus in sewage through their roots, reducing the risk of eutrophication of water bodies. Secondary wetland treatment focuses on utilizing the biochemical reactions of wetland units to further purify difficult-to-degrade substances and residual nutrients in sewage. In the secondary wetland, by controlling the water level and dissolved oxygen content, nitrification and denitrification processes are achieved, and ammonia nitrogen is converted into nitrogen gas and released into the atmosphere. The matrix material continues to play an adsorption role, especially for the removal of heavy metals and difficult-to-degrade organic matter, and ion exchange occurs at the same time to further remove pollutants in the water. Through treatment in the secondary wetland, the water quality is further improved and can meet higher discharge standards or reuse requirements.

[0081] The primary wetland treatment reduces most of the suspended solids and organic matter in the sewage, providing more favorable conditions for the secondary wetland treatment, making the biochemical reaction more efficient. Through two-stage treatment, the hydraulic load and organic load of the wetland system can be reasonably distributed, avoiding excessive load in a single treatment link, and improving the stability and treatment efficiency of the system. The two-stage wetland treatment complements each other. Even if the primary wetland treatment effect is not good at a certain period of time, the secondary wetland can further purify it to ensure that the effluent water quality is stable and meets the standards.

[0082] According to the characteristics of sewage and treatment objectives, the hydraulic load and organic load entering the primary and secondary wetlands are precisely controlled to ensure that both wetlands can operate at their best. Through real-time monitoring of water quality indicators such as pH value and dissolved oxygen, the operating parameters are adjusted in a timely manner to optimize the treatment effect of each wetland. The wetland plants are pruned and managed regularly to maintain their healthy growth; the matrix materials are regularly inspected and replaced to maintain their filtration and adsorption performance.

[0083] In one embodiment, in a rural area, primary wetland treatment is used to remove most suspended matter and organic matter, and secondary wetland treatment further removes nutrients such as nitrogen and phosphorus, and the final effluent meets the farmland irrigation standard. In an urban park, a primary wetland is designed to initially intercept suspended matter and particulate matter in rainwater, and a secondary wetland further purifies rainwater through biochemical reactions to increase the utilization value of rainwater. In an industrial park, primary wetland treatment is used to reduce the concentration of toxic and harmful substances in wastewater, and a secondary wetland ensures that wastewater meets discharge standards or reuse requirements through deep purification.

[0084] In summary, primary wetland treatment and secondary wetland treatment achieve efficient purification of sewage through different mechanisms and process flows. The primary wetland is mainly responsible for the initial removal of suspended solids and organic matter, while the secondary wetland focuses on further removal of nutrients and refractory substances through biochemical reactions. The synergistic effect of the two not only improves the treatment efficiency, but also enhances the stability and reliability of the system.

[0085] Artificial wetland systems treat sewage by simulating the functions of natural wetlands. According to the differences in water flow paths and water levels, artificial wetland systems can be divided into three types: surface flow wetlands, horizontal subsurface flow wetlands, and vertical subsurface flow wetlands. Different types of wetlands have different requirements for water levels, so water level factors also need to be considered when configuring plants.

[0086] 1) Surface flow wetlands

[0087] Water level: The water level is usually near or above the surface of the wetland bed.

[0088] Plant configuration: High water levels are suitable for water-tolerant plants, such as reeds, cattails, and water hyacinths. These plants can grow on the water surface, and their roots can penetrate deep into the water to provide oxygen transmission. Medium water levels select some semi-aquatic plants, such as rushes and papyrus, which can grow under partially submerged conditions. Low water levels are equipped with some plants that tolerate moisture but not long-term flooding, such as Viola yedoensis and moss.

[0089] 2) Horizontal subsurface flow wetland

[0090] Water table: Water flows horizontally below the surface of the wetland bed, and the water table is usually below the wetland surface.

[0091] Plant configuration: The roots of plants at high water levels need to be able to adapt to a humid environment, but do not need to be immersed in water for a long time, such as canna and pickerel grass. Medium water levels are suitable for plants with deep roots, such as irises and pennisetum, which can grow in a moist substrate. Low water levels select some semi-drought-tolerant plants, such as willows and thatch, which can grow in occasional wet conditions.

[0092] 3) Vertical subsurface wetland

[0093] Water table: Water flows vertically through the fill layer, and the water table is usually below the wetland surface.

[0094] Plant configuration: High water levels require plants whose roots can withstand a certain amount of water pressure, such as some aquatic or semi-aquatic plants, such as reeds and cattails. Medium water levels select plants with deeper roots, such as aquatic cannas and rushes, which can grow in the filler layer and promote oxygen transfer. Low water levels select some plants with shallow roots but moisture-tolerant, such as mosses and some ground cover plants.

[0095] By rationally configuring plants in different types of wetlands, the sewage treatment effect of artificial wetlands can be optimized while enhancing their ecological functions and landscape value.

[0096] Step S14, treating the sewage after wetland treatment.

[0097] The effluent treatment of sewage after wetland treatment includes filtration treatment, disinfection treatment, stabilization pond treatment, adsorption treatment, coagulation sedimentation treatment and comprehensive treatment.

[0098] Specifically, the effluent treatment of sewage after wetland treatment is an important step to ensure that the water quality meets the discharge standards or reuse requirements. This process includes filtration treatment, disinfection treatment, stabilization pond treatment, adsorption treatment, coagulation sedimentation treatment and comprehensive treatment to ensure that the water quality is fully purified.

[0099] Filtration treatment is mainly used to remove suspended solids and particulate matter remaining in the water after wetland treatment. Sand filters, fiber filters or microfiltration equipment are usually used, and appropriate filtration devices are selected according to the amount of water to be treated and the water quality requirements. Filtration speed, filtration accuracy and backwashing frequency are key parameters and need to be adjusted according to the water quality characteristics.

[0100] Disinfection treatment aims to kill bacteria, viruses and other microorganisms in water to ensure that the water quality meets sanitary standards. Common methods include chlorine disinfection, ultraviolet disinfection and ozone disinfection. The dosage and contact time of the disinfectant need to be strictly controlled to avoid the formation of by-products.

[0101] Stabilization ponds simulate natural water bodies and use sunlight, microorganisms and aquatic plants to further purify water. Stabilization ponds are usually shallow to increase the water surface area and improve photosynthesis efficiency. They have lower operating costs and better landscape effects, and are suitable for areas with abundant land resources.

[0102] Adsorption treatment is mainly used to remove dissolved organic matter and color substances in water to improve water transparency. Activated carbon is the most commonly used adsorption material, and other adsorbents can also be used as needed. The adsorption material needs to be replaced regularly to ensure the adsorption effect.

[0103] Coagulation and sedimentation treatment removes fine suspended matter by adding coagulants to promote the aggregation and sedimentation of water. Selecting the right coagulant and dosage, as well as mixing and settling time, is crucial to improving the coagulation effect. Commonly used equipment includes coagulation reactors and sedimentation tanks, and the design should take into account easy maintenance and mud discharge.

[0104] Comprehensive treatment is to combine the above-mentioned treatment methods to achieve the best effluent water quality. According to the water quality target and discharge standard, the appropriate treatment combination is selected. It is necessary to coordinate the operation and management of each treatment unit to ensure the efficient operation of the overall system.

[0105] In summary, the treatment of sewage effluent after wetland treatment covers multiple aspects such as filtration treatment, disinfection treatment, stabilization pond treatment, adsorption treatment, coagulation sedimentation treatment and comprehensive treatment. These steps work together to ensure that the sewage can be deeply purified and meet the standards for discharge or reuse. In practical applications, the treatment method should be flexibly selected and optimized according to the specific water quality requirements and environmental conditions to achieve the best treatment effect.

[0106] In one embodiment, the artificial wetland treatment control system code of the present invention is as follows:

[0107]

[0108]

[0109] Among them, the RemoteMonitoringSystem class is used to remotely monitor and control the operation of the wetland unit; the WetlandUnit class represents an artificial wetland unit with the function of treating sewage; in the main function, two wetland units (primary and secondary) are initialized and added to the monitoring system for monitoring and processing.

[0110] Step S15: transport the treated sewage to a designated location.

[0111] Specifically, the treated sewage is discharged through the outlet pipe or reused for other purposes. This step is the final link in the sewage treatment process and is also the key to achieving water resource recycling.

[0112] Before being discharged, treated sewage must meet national or regional environmental protection standards, including requirements for water quality such as pH value, suspended solids concentration, organic matter content, nitrogen and phosphorus content, and other indicators. Through online monitoring equipment or regular sampling and analysis, ensure that the effluent quality continues to meet the discharge standards. Treated sewage can be discharged directly into rivers, lakes or oceans, but relevant environmental protection laws and regulations must be observed to ensure that the receiving water body will not be polluted. Treated water can also be used for farmland irrigation, which helps to save water resources and reduce groundwater exploitation. According to the water quality requirements for industrial water, treated water can also be used for cooling, washing and other processes that do not directly contact the product. Treated water can also be used for lake water replenishment, landscape rivers and artificial waterfalls in urban parks. Treated water can also be used to replenish the water volume of artificial wetlands or other ecological water bodies to maintain ecological balance.

[0113] The treated sewage is discharged through the outlet pipe or reused for other purposes. This step reflects the ultimate goal of sewage treatment - protecting the environment and saving resources. Whether it is discharged or reused, it must be ensured that the water quality meets the corresponding standards to protect the ecological environment and human health. At the same time, this step also requires strict management and meticulous maintenance to ensure the efficient operation and long-term stability of the entire system.

[0114] The modular sewage treatment method of the present invention further includes the operation of a remote monitoring and management platform, which is the key to achieving efficient and intelligent management of the sewage treatment system.

[0115] The composition of the remote monitoring system: sensor network, install a variety of sensors in the sewage treatment system, such as water level meter, flow meter, water quality online monitoring instrument, etc., to collect data from each treatment unit in real time. Data transmission equipment, transmit the data collected by the sensor to the remote monitoring center by wireless or wired means. The monitoring center is equipped with a computer system and professional software for receiving, processing and analyzing data, and issuing control instructions. Remote monitoring can display the operating status of the sewage treatment system in real time, including water quality parameters, equipment operation status, etc. When the monitored data exceeds the preset range, the system will automatically issue an early warning to remind the management personnel to deal with it in time. According to the real-time monitoring data, the system can automatically adjust the operating parameters of the equipment, such as adjusting the start and stop of the pump, the opening and closing of the valve, etc. Establishing a remote management platform will help data analysis and decision support: analyze the large amount of collected data to provide a scientific basis for the optimized operation of the sewage treatment system. The remote management platform can help diagnose system failures and guide on-site personnel to make repairs or adjustments. Monitor and manage the energy consumption of the sewage treatment system to achieve the goal of energy saving and consumption reduction.

[0116] The remote monitoring and management platform in the modular sewage treatment method is an important means to realize the modernization and intelligence of the sewage treatment system. Through real-time monitoring, data analysis, automatic control and other functions, the remote monitoring and management platform significantly improves the efficiency and reliability of sewage treatment, and also provides managers with convenient management tools.

[0117] The present invention integrates the modules of the above functions into one body and works together to ensure that the sewage meets environmental standards before being discharged or reused, thereby forming a mobile treatment device. The device consists of three main parts, namely, a pretreatment module, a pump station and a control system. The pretreatment module is mainly used to remove large particles and suspended matter in the sewage. This step is crucial to protecting the equipment in the subsequent treatment links and improving the treatment efficiency. Through pretreatment, larger impurities are filtered out to prevent blockage and damage to subsequent treatment equipment. The pump station is responsible for providing power throughout the entire treatment process to transport sewage from one treatment unit to another. The design of the pump station needs to take into account energy efficiency and reliability to ensure stable operation of the system. The control system is the core of the entire mobile treatment device, which is responsible for monitoring and adjusting the treatment process. Modern control systems usually use automation technology to collect and analyze data in real time, optimize treatment parameters, and ensure that the effluent water quality meets the standards.

[0118] The present invention provides a reliable solution for sewage treatment in various occasions with its flexible and efficient characteristics. This device not only solves the limitations of traditional sewage treatment facilities, but also improves the treatment effect and operation efficiency through modularization and automation technology. It can be applied to some places such as rural areas where the level of urban sewage management and treatment is not achieved due to poor environmental conditions or economic levels, and therefore requires a modular, easy to assemble, small footprint and sewage treatment system that improves sewage treatment efficiency.

[0119] In one embodiment, if Figure 4a to Figure 4b As shown, an artificial wetland is created by distributing and designing the purification plants based on their characteristics of water flow. Figure 4a The flow state conversion unit in the double dashed rectangular frame can be set up in multiple units according to the wastewater treatment space. Ground-close plants are arranged in the undercurrent area to achieve undercurrent. This means that this water weir adjustment and tailgate control are generally used in river engineering model tests. That is, when doing the test, by continuously controlling the water weir and the tailgate, the purpose of controlling the water flow velocity and flow rate can be achieved, so that the hydrodynamic characteristics under different working conditions can be achieved. The specific steps are:

[0120] 1) Water flows into the water tank, and the water pipe and the water measuring weir can control the water flow and ensure the uniform water flow: In this process, the water measuring weir plays a key role. By setting a water measuring weir at the outlet of the water pipe, the water flow entering the water tank can be accurately controlled. The water measuring weir adjusts the head height on the weir to meet different flow requirements, thereby ensuring the uniform distribution of water flow in the channel and avoiding uneven water flow caused by excessive or insufficient flow.

[0121] 2) Water flows through the trash rack, which can make the water flow smooth, uniform and stable: The trash rack is mainly used to intercept debris in the water to prevent it from entering the subsequent water treatment system. After passing through the trash rack, the suspended matter and larger particles in the water flow are removed, making the water flow smoother, more uniform and more stable, which is conducive to the subsequent treatment process.

[0122] 3) Surface flow, so that the wastewater is fully in contact with oxygen and ensures that the wastewater is fully oxidized: In the design of surface flow wetlands, water flows on the surface of the wetland, which can increase the contact between the wastewater and oxygen in the air, promote the oxidation and decomposition of organic matter in the wastewater, and improve the effect of wastewater treatment.

[0123] 4) Arrange purification plants along two zone lines; surface flow turns to horizontal undercurrent, fully contacting with plants: In the wetland system, plants are arranged along specific zone lines, which helps the wastewater to fully contact with the plant roots during the process of turning the water flow to horizontal undercurrent. The plant roots can not only absorb and degrade pollutants, but also provide a place for microbial growth.

[0124] 5) Before the S-shaped rigid plants, the water flow rises from the plane undercurrent, and is constantly adjusted and fully mixed, forming a vertical undercurrent behind the S-shaped rigid plants: the S-shaped rigid plants can guide the water flow to switch between the plane undercurrent and the vertical undercurrent. When the water flows through these plants, the direction and speed will change, so that the water flow can fully contact the plant roots and effectively remove pollutants. The flow state of the vertical undercurrent is conducive to deep filtration and more efficient biodegradation.

[0125] 6) The flow pattern of vertical undercurrent is constantly adjusted, and then adjusted to surface flow, fully contacting with oxygen, and then going through surface flow - plane undercurrent - vertical undercurrent - surface flow: This flow pattern conversion design is to enhance the effect of water treatment. Vertical undercurrent helps deep treatment, and after conversion to surface flow, it can increase oxygen contact and promote aerobic biodegradation. This cycle process can improve the sewage treatment capacity of the system.

[0126] 7) Finally, the water is collected in the pool as a surface flow, completing a cycle: After a series of treatment processes, the water flow is finally collected in the pool as a surface flow, completing a complete cycle. This process not only removes pollutants in the sewage, but also improves the water purification effect through the conversion of different flow states. The collected water can be used for irrigation, groundwater recharge or other non-drinking purposes.

[0127] By setting a water-measuring weir at the entrance of the water tank, the water flow entering the system can be accurately controlled to ensure that the water flow is evenly distributed throughout the system, which is crucial for the stable operation of the water treatment system. The use of trash racks is to remove large particles of impurities and floating objects in the water to prevent these substances from affecting the efficiency and quality of subsequent treatment processes. The surface flow stage promotes the oxidation of pollutants and the exchange of gases in the wastewater, which helps to remove organic matter and improve water quality. Then through the conversion of different flow patterns (surface flow, plane undercurrent, vertical undercurrent), the wastewater treatment system realizes a multi-stage and multi-level purification process, improving the treatment efficiency and effect. The purification plants arranged along the two zone lines not only help to turn and mix the water flow, but also provide growth media for microorganisms through the plant roots, enhancing biodegradation. The design of the S-shaped stiff plants allows the water flow to flow between the plants, increasing the contact time between the water flow and the plant roots, and improving the removal rate of pollutants. The continuous adjustment of the flow pattern (conversion between surface flow, plane undercurrent, and vertical undercurrent) helps to break the laminar flow in the water flow, promote the mixing and dispersion of pollutants, and increase the contact with oxygen, thereby improving the purification effect. Finally, the water flows into the pool in the form of surface flow, completing a cycle. This process reflects the closedness and sustainability of the system, that is, after a series of treatment steps, the wastewater can be used for other purposes or returned to natural water bodies. The present invention is a design concept and working principle of an efficient, multi-level, eco-friendly wastewater treatment system. The system achieves the purification and resource utilization of wastewater by combining physical, chemical and biological processes, reflecting the emphasis of modern water treatment technology on environmental protection and sustainable utilization of resources.
