Technical Field

[0001] This application relates to the field of ecological and environmental technology, specifically to a method and apparatus for ecological and environmental remediation of water pollution. Background Technology

[0002] In related technologies, when carrying out ecological and environmental remediation of water pollution, deep purification units and biological purification units can be arranged according to the specific pollution situation of each water section based on the monitored pollution data.

[0003] However, the biological purification units described above have certain limitations. The performance of the biological compound inoculants and plants is particularly affected by environmental factors such as temperature and season. For example, in cold weather, the activity of microorganisms may be inhibited, and the growth of aquatic plants will also be affected, leading to a reduction in purification efficiency. Summary of the Invention

[0004] To address the technical problem of reduced purification efficiency due to limitations in biological purification units, this application aims to provide a method and apparatus for the ecological environment treatment of water pollution. The specific technical solution adopted is as follows:

The limiting impact of an environmental factor is used to characterize the impact of that environmental factor on the limitations of the biological purification unit. Based on the limiting impact of each environmental factor, determine the biological purification limitations of the target water segment. Based on the biological purification limitations of the target water segment, adjust the original purification unit ratio of the target water segment to obtain the adjusted purification unit ratio, which is the ratio of the number of deep purification units to the number of biological purification units.

[0009] Optionally, adjusting the original purification unit ratio of the target water segment based on the biological purification limitations of the target water segment to obtain an adjusted purification unit ratio includes: acquiring monitoring data of other water segments, wherein the other water segments are upstream water segments of the target water segment; determining the interference effect of the other water segments on the biological purification limitations of the target water segment based on the monitoring data of the other water segments; and adjusting the original purification unit ratio of the target water segment based on the interference effect of the other water segments on the biological purification limitations of the target water segment and the biological purification limitations of the target water segment to obtain an adjusted purification unit ratio.

[0010] Optionally, the above-mentioned adjustment of the original purification unit ratio of the target water area based on the interference of the other water area segments on the biochemical purification limitations of the target water area segment and the biological purification limitations of the target water area segment to obtain the adjusted purification unit ratio includes: determining the adjusted purification unit ratio based on the product of the interference of the other water area segments on the biochemical purification limitations of the target water area segment, the biological purification limitations of the target water area segment, and the original purification unit ratio of the target water area segment.

[0011] Optionally, the monitoring data includes water flow velocity. The determination of the interference effect of the other water segment on the biological purification limitations of the target water segment based on the monitoring data of the other water segment includes: determining the hydraulic interference of the upstream water segment on the downstream water segment in each pair of adjacent water segments based on the water flow velocity of the upstream water segment and the water flow velocity of the downstream water segment in each pair of adjacent water segments; and determining the interference effect of the other water segment on the biochemical purification limitations of the target water segment based on the hydraulic interference of the upstream water segment on the downstream water segment in each pair of adjacent water segments and the biological purification limitations of each water segment in the other water segments.

[0012] Optionally, the above-mentioned determination of the hydraulic interference of the upstream water segment on the downstream water segment in each pair of adjacent water segments based on the water flow velocity of the upstream water segment and the water flow velocity of the downstream water segment in each pair of adjacent water segments includes: determining the ratio of the water flow velocity of the upstream water segment to the water flow velocity of the downstream water segment in each pair of adjacent water segments as the hydraulic interference of the upstream water segment on the downstream water segment in each pair of adjacent water segments.

[0013] Optionally, the above-mentioned determination of the interference effect of other water segments on the biochemical purification limitations of the target water segment based on the hydraulic interference of the upstream water segment on the downstream water segment in each pair of adjacent water segments and the biological purification limitations of each other water segment includes: determining the water quality interference of the upstream water segment on the downstream water segment in each pair of adjacent water segments based on the hydraulic interference of the upstream water segment on the downstream water segment in each pair of adjacent water segments and the biological purification limitations of the upstream water segment in each pair of adjacent water segments; and determining the interference effect of other water segments on the biochemical purification limitations of the target water segment based on the water quality interference of the upstream water segment on the downstream water segment in each pair of adjacent water segments and the biological purification limitations of the downstream water segment in each pair of adjacent water segments.

[0014] Optionally, the above-mentioned determination of the interference effect of other water segments on the biological purification limitations of the target water segment based on the water quality disturbance of the upstream water segment to the downstream water segment in each pair of adjacent water segments, and the limitations of biological purification of the downstream water segment within each pair of adjacent water segments, includes: determining the interference effect of each pair of adjacent water segments based on the product of the water quality disturbance of the upstream water segment to the downstream water segment in each pair of adjacent water segments and the limitations of biological purification of the downstream water segment within each pair of adjacent water segments; and determining the interference effect of other water segments on the biological purification limitations of the target water segment based on the sum of the interference effects of each pair of adjacent water segments.

[0015] This application also provides a device for the ecological environment management of water pollution, which includes an intelligent sensor module, a configuration module, and a management module.

[0016] This intelligent sensor module is used to acquire monitoring data of the target water area, including the monitoring values ​​of environmental factors and dissolved oxygen concentration at each time.

[0017] This configuration module is used to determine the limiting impact of each environmental factor based on the monitored values ​​of each environmental factor and the monitored values ​​of dissolved oxygen concentration at each time. The limiting impact of an environmental factor is used to characterize the impact of that environmental factor on the limitations of the biological purification unit.

[0018] This configuration module is also used to determine the limitations of biological purification in the target water segment based on the limiting impact of each environmental factor.

[0019] The configuration module is also used to adjust the original purification unit ratio of the target water area based on the biological purification limitations of the target water area, so as to obtain the adjusted purification unit ratio, which is the ratio of the number of deep purification units to the number of biological purification units.

[0020] This treatment module is used to purify water based on the adjusted ratio of purification units.

[0021] This application has the following beneficial effects:

[0022] By analyzing the relationship between dissolved oxygen concentration and monitoring values ​​of each environmental factor at each moment in the target water segment, the limiting impact of each environmental factor was quantified. Based on the limiting impact of each environmental factor, the limitations of biological purification in the target water segment were determined. This allowed for an accurate assessment of the purification effect of the biological purification unit in the target water segment. Based on this, the original purification unit ratio of the target water segment was adjusted to obtain the adjusted purification unit ratio. Water purification was then carried out based on the adjusted purification unit ratio, making the purification unit ratio more suitable for the current environment, offsetting the impact of environmental factors, and improving the effectiveness and flexibility of water purification.

[0027] To further illustrate the technical means and effects adopted by this application to achieve its intended purpose, the following, in conjunction with the accompanying drawings and preferred embodiments, details the specific implementation, structure, features, and effects of a water pollution ecological environment treatment method and apparatus proposed in this application. In the following description, different "one embodiment" or "another embodiment" do not necessarily refer to the same embodiment. Furthermore, specific features, structures, or characteristics in one or more embodiments can be combined in any suitable form.

[0028] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0029] Water pollution mainly includes chemical pollution such as heavy metals and organic pollutants, biological pollution such as pathogenic microorganisms and invasive species, and physical pollution such as plastic waste and suspended particulate matter. These pollutants not only affect water quality, causing eutrophication and hypoxia, but also seriously threaten the survival of aquatic organisms and the ecological balance, ultimately posing a threat to the entire ecosystem and human health. Therefore, ecological and environmental remediation of water pollution is crucial, with the aim of restoring and maintaining the natural ecological functions of water bodies, improving water quality, and ensuring the sustainable use of water resources.

[0030] In general, when carrying out ecological and environmental remediation of water pollution, the first step is to deploy different purification units based on the monitored pollution data and the specific pollution situation of each section of the water. Deep purification units use chemical reactions or fine filtration technology, employing chemical reagents or special materials to remove harmful substances from the water; for example, activated carbon adsorption effectively removes organic pollutants. Biological purification units introduce bio-compound microbial agents and aquatic plants, utilizing microorganisms to degrade organic matter in the water, while plants absorb nutrients and heavy metals, forming a natural purification loop. These two purification methods complement each other in removing pollutants.

[0031] In existing technologies, biological purification units for the ecological environment remediation of polluted water bodies have certain limitations. The performance of bio-compound microbial agents and plants is particularly significantly affected by environmental factors such as temperature and season. In cold weather conditions, the activity of microorganisms may be inhibited, and the growth of aquatic plants may also be affected, leading to a reduction in purification efficiency. Especially in sudden water pollution incidents, the response speed of biological purification may be delayed, making it difficult to quickly and effectively resolve water quality deterioration. In such cases, the effectiveness of water purification is limited, potentially preventing timely remediation of water pollution. In contrast, deep purification units are more stable and less affected by these limitations.

[0032] The following description, in conjunction with the accompanying drawings, details a specific scheme for a water pollution ecological environment treatment method provided in this application.

[0033] Please see Figure 1 The diagram shows a flowchart of a water pollution ecological environment treatment method provided in one embodiment of this application.

[0034] like Figure 1 As shown, this method for ecological environment management of water pollution includes S101-S105.

[0035] S101. Obtain monitoring data for the target water area.

[0036] The monitoring data includes the monitoring values ​​of environmental factors at each time point and the monitoring values ​​of dissolved oxygen concentration at each time point.

[0037] In this embodiment of the application, a water area can be divided into multiple water area segments, and the target water area segment is any one of the multiple water area segments.

[0038] Optionally, different environmental sensors, such as temperature sensors and humidity sensors, can be installed in each water segment to monitor environmental changes in each water segment; dissolved oxygen sensors can be installed in each water segment to monitor the dissolved oxygen concentration in the water in real time to ensure the living environment of aquatic organisms; and flow velocity sensors can be installed at the outlet of each water segment to monitor changes in water flow velocity.

[0039] Optionally, the environmental factor may include temperature, humidity, water flow rate, etc.

[0040] S102. Based on the monitoring values ​​of each environmental factor at each time point and the monitoring values ​​of dissolved oxygen concentration at each time point, determine the limiting impact of each environmental factor.

[0041] The limitation effect of an environmental factor is used to characterize the impact of that environmental factor on the limitations of the biological purification unit.

[0042] Understandably, in the process of ecological environment governance based on biological purification units, the purification effect of the bio-compound inoculants and plants within these units is often significantly affected by temperature, dissolved oxygen content, light, and other environmental conditions. For example, low temperatures may lead to reduced microbial activity. The concentration of dissolved oxygen, on the other hand, affects the growth and activity of aerobic microorganisms.

[0043] It should be understood that the greater the limiting influence of an environmental factor, the greater the limitation of the biological purification unit in purifying this section of water.

[0044] In one alternative implementation, the dissolved oxygen rate at each time step can be determined based on the dissolved oxygen concentration at each time step, and then the limiting impact of each environmental factor can be determined based on the correlation between the change of each environmental factor and the change of the dissolved oxygen rate.

[0045] Alternatively, the limiting influence of an environmental factor may satisfy the following formula:

[0046]

[0047] in, Indicates the target water area The Middle The limiting influence of individual environmental factors This represents the Pearson correlation coefficient. Indicates the first The monitoring values ​​of each environmental factor at time 1. Indicates the first The monitoring values ​​of the environmental factors at the second time point. Indicates the first The monitoring values ​​of each environmental factor at each moment, Indicates the target water area Dissolved oxygen rate at the first moment. Indicates the target water area Dissolved oxygen rate at the second moment. Indicates the target water area Dissolved oxygen rate at each corresponding time point.

[0048] Understandably, a high Pearson correlation coefficient between changes in a certain environmental factor and changes in dissolved oxygen rate indicates that this environmental factor can directly affect the operational efficiency of the biological purification unit within a certain range. This is because the concentration of dissolved oxygen directly affects the metabolic activities of microorganisms, thus revealing the limitations of the biological purification unit under the influence of different environmental factors.

[0049] S103. Based on the limited impact of each environmental factor, determine the limitations of biological purification in the target water area.

[0050] It should be understood that the biological purification limitation of the target water segment is used to characterize the effectiveness of the biological purification unit in purifying the target water segment.

[0051] It should be understood that different environmental factors have different weights. The greater the limiting influence of an environmental factor, the greater the impact of changes in the monitored value of that environmental factor on the performance of the biological purification unit, and therefore the greater the weight of that environmental factor should be. The greater the change in the value of that environmental factor, the greater the impact of that environmental factor on the performance of the biological purification unit. Therefore, the limitations of biological purification in the target water area can be determined based on the limiting influence of that environmental factor combined with the change in the value of that environmental factor.

[0052] In one alternative implementation, the maximum span value of each environmental factor is determined based on the monitoring value of each environmental factor at each time point; then, the biological purification limitations of the target water segment are determined based on the limited impact of each environmental factor and the maximum span value of each environmental factor.

[0053] Optionally, the limitations of biological purification in the target water segment satisfy the following formula:

[0054]

[0055] in, Indicates the target water area The limitations of biological purification Indicates the first One environmental factor, Indicates the target water area The Middle The limiting influence of individual environmental factors Indicates the quantity of environmental factors. Indicates the first The environmental factor in the first The monitoring value at each moment, Indicates the first The environmental factor in the first The monitoring value at each moment, This represents the collection of all moments. Indicates the first The maximum span value of each environmental factor. This represents the maximum and minimum value normalization function. This represents the normalized result of the maximum span value of all environmental factors, which can eliminate the dimensional differences between different environmental factors.

[0056] Based on the above formula, it should be understood that, It represents the sum of the limiting effects of all environmental factors. Indicates the first The influence weight of each environmental factor, through Allocating weights ensures that more significant environmental factors account for a larger proportion of the limitations of bioremediation. To indicate the degree of drastic change, summation is performed using the outermost layer. By summing the impact weight of each environmental factor with the normalized maximum span value, we can achieve a dual consideration of the magnitude of the impact and the intensity of the change, and accurately quantify the limitations of biological purification.

[0057] S104. Based on the limitations of biological purification in the target water area, the original purification unit ratio of the target water area is adjusted to obtain the adjusted purification unit ratio.

[0058] The purification unit ratio is the ratio of the number of deep purification units to the number of biological purification units.

[0059] It should be understood that the original purification unit ratio is the purification unit ratio set after the initial assessment of the target water area. This original purification unit ratio may be inaccurate. After testing based on the method provided in the embodiments of this application, the original purification unit ratio can be further adjusted.

[0060] Optionally, the deep purification unit includes purification methods such as membrane filtration and ozone treatment, and the biological purification unit is set after the deep purification unit to further degrade organic matter and nutrients by utilizing the metabolic action of microorganisms.

[0061] In one alternative implementation, the treatment unit for the target water area may further include a primary purification unit and a slow filter purification unit. The primary purification unit is located upstream of the target water area and is used to remove larger particles or sediments. The slow filter unit is located after the primary purification unit and before the deep purification unit, and further purifies the water quality using natural filtration.

[0062] In this embodiment, only the ratio of the deep purification unit to the biological purification unit is adjusted.

[0063] It should be understood that when the biological purification in the target water area is limited, it indicates that the purification effect of the biological purification unit in that target water area is poor. The biological compound agents and plants in the biological purification unit have low efficiency in treating pollutants and are not easy to maintain water quality. In this case, the purification effect based on the original purification unit ratio is poor. Therefore, the purification unit ratio can be adjusted to increase the proportion and number of deep purification units, which can supplement the deficiencies of biological purification, enhance the pollutant removal effect, and achieve a better purification effect.

[0064] If the biological purification limitation in the target water area is relatively low, it indicates that the performance of the biological purification unit in that target water area is good and its treatment capacity is sufficient to cope with the conventional pollution load. At this time, the proportion of biological purification units can be increased to better utilize the existing biological treatment mechanism, further enhance its natural purification capacity, and improve water quality stability and ecological health.

[0065] In one alternative implementation, the adjusted purification unit ratio can be determined based on the product of the biological purification limitations of the target water segment and the original purification unit ratio of the target water segment.

[0066] Optionally, after normalizing the biological purification limitation of the target water segment as described above, the biological purification limitation of the target water segment is less than 1. In this case, the biological purification limitation of the target water segment can be increased by 1 and then multiplied by the original purification unit ratio of the target water segment to obtain the adjusted purification unit ratio.

[0067] It should be understood that adding 1 to the biological purification limitation can prevent the biological purification limitation from being less than 1. Since the purification unit ratio is the ratio of the number of deep purification units to the number of biological purification units, when the sum of the biological purification limitation plus 1 is multiplied by the original purification unit ratio, the original purification ratio can be increased, and the proportion of deep purification units can be increased.

[0068] S105. Purify water quality based on the adjusted purification unit ratio.

[0069] In one alternative implementation, the number of deep purification units and the number of biological purification units are configured based on the adjusted purification unit ratio to purify the water.

[0070] Optionally, the number of deep purification units or biological purification units obtained based on the adjusted purification unit ratio may not be an integer. In this case, the actual number of deep purification units or biological purification units can be determined by rounding up.

[0071] Optionally, governance goals can be set during the purification process, which may include water quality improvement, ecological restoration, and biodiversity protection.

[0072] Optionally, timelines and milestones can be set to effectively monitor the entire governance process.

[0073] Optionally, during the implementation phase, strengthened management and collaboration are necessary, including hiring professional technical teams and equipping them with the necessary facilities and equipment to ensure the smooth implementation of various governance measures and the efficient operation of each governance unit. Simultaneously, a water quality monitoring and feedback mechanism can be established to regularly assess the operational effectiveness and water quality changes of each governance unit, and to dynamically adjust and optimize based on monitoring data. Through multi-party collaboration and scientific management, a comprehensive governance system can be formed, encompassing source control, process control, and ultimately ecological restoration and harmonious coexistence, to ensure the sustainable development of the aquatic ecological environment.

[0074] In one alternative implementation, the adjusted proportion of purification units for each water segment can be determined, and then the entire water segment can be purified based on the adjusted proportion of purification units.

[0075] In this embodiment, the limiting influence of each environmental factor is quantified by the relationship between the dissolved oxygen concentration of the target water segment at each time and the monitoring value of each environmental factor. Then, based on the limiting influence of each environmental factor, the limitations of biological purification in the target water segment are determined. This allows for an accurate assessment of the purification effect of the biological purification unit in the target water segment. Based on this, the original purification unit ratio of the target water segment is adjusted to obtain the adjusted purification unit ratio. Water purification is then carried out based on the adjusted purification unit ratio, which makes the purification unit ratio more suitable for the current environment, offsets the influence of environmental factors, and improves the effectiveness and flexibility of water purification.

[0076] Combination Figure 1 ,like Figure 2 As shown in one implementation of this application embodiment, the original purification unit ratio of the target water area is adjusted based on the biological purification limitations of the target water area to obtain the adjusted purification unit ratio, which can be further implemented through S201-S203.

[0077] S201. Obtain monitoring data for other water sections.

[0078] Among them, the other water segment is the upstream water segment of the target water segment.

[0079] It should be understood that in a water system, since multiple water sections are interconnected, the health status of the water is not only affected by the purification capacity of a single water section, but also by the combined effect of its upstream water sections. The water quality of the upstream water sections may also affect the water quality of the target water section. Therefore, the proportion of purification units in the target water section can be further precisely adjusted by combining the influence of the upstream water sections on the target water section.

[0080] In this embodiment of the application, the method for obtaining monitoring data of other water segments is the same as or similar to the method for obtaining monitoring data of the target water segment, and will not be described again here.

[0081] S202. Determine the interference impact of other water sections on the target water section based on monitoring data from other water sections.

[0082] It should be understood that the interference of other water sections on the target water section specifically refers to the interference with the limitations of biological purification in the target water section. When the interference of other water sections on the target water section is significant, it indicates that the ecological environment of the target water section is greatly affected by the water quality of other water sections. In this case, the biological purification unit of the target water section may not be able to effectively cope with the pollutant load from upstream or adjacent water sections, and the water quality may deteriorate.

[0083] In one implementation of this application, the monitoring data also includes water flow velocity. Based on the water flow velocity of the upstream water segment and the downstream water segment in each pair of adjacent water segments in other water segments, the hydraulic interference of the upstream water segment on the downstream water segment in each pair of adjacent water segments can be determined. Then, based on the hydraulic interference of the upstream water segment on the downstream water segment in each pair of adjacent water segments and the biological purification limitations of each water segment in other water segments, the interference effect of the other water segments on the biochemical purification limitations of the target water segment can be determined.

[0084] It should be understood that in the dynamics of water flow within a water segment, flow velocity is a crucial factor influencing hydraulic disturbances. When the flow velocity in the upstream water segment of a target water segment is high, the target water segment is significantly affected by disturbances from the upstream water segment. Since this other water segment may comprise multiple water segments, it can be divided into several adjacent water segments, each including an upstream water segment and a downstream water segment.

[0085] It should be understood that the greater the relative flow velocity in the upstream section of each adjacent water segment, the more significant the hydraulic disturbance to the downstream section.

[0086] In one alternative implementation, the ratio of the water flow velocity of the upstream water segment to the water flow velocity of the downstream water segment in each pair of adjacent water segments can be determined as the hydraulic interference of the upstream water segment on the downstream water segment within each pair of adjacent water segments.

[0087] Optionally, the hydraulic disturbance of the upstream water segment to the downstream water segment in an adjacent water segment satisfies the following formula:

[0088]

[0089] in, Indicates adjacent water sections Middle and upper reaches of the waters For downstream water section Hydraulic interference, Indicates the upstream water section water flow speed, Indicates the upstream water section The speed of water flow.

[0090] Understandably, for each pair of adjacent water segments, if the flow velocity at the outlet of the upstream segment is greater than that at the outlet of the downstream segment, it indicates that the kinetic energy and volume of the water body encounter stronger impact and disturbance in the downstream segment. This higher flow velocity carries more pollutants and sediments, increasing the pollution burden on the downstream segment. Furthermore, a higher flow velocity also implies greater potential energy, easily triggering turbulence and water flow disturbance, altering the flow pattern in the downstream segment, and further affecting water mixing, sedimentation, and biological activity. Therefore, the ratio of the flow velocity of the upstream segment to the flow velocity of the downstream segment within each pair of adjacent water segments accurately reflects the difference in flow velocity between the upstream and downstream segments. Based on this, the hydraulic interference of the upstream segment on the downstream segment within each pair of adjacent water segments can be accurately determined.

[0091] It should be understood that for each pair of adjacent water segments, when the upstream water segment has a significant hydraulic disturbance on the downstream water segment, pollutants and other substances in the water flow will enter the downstream segment at a higher concentration and velocity, and the water quality of the upstream water segment will also affect the water quality of the downstream water segment. If the biological purification capabilities of the upstream water segment are also limited and cannot effectively reduce the pollutant load in the water, then the water quality of the downstream water segment will become even worse.

[0092] In one alternative implementation, the water quality disturbance of the upstream water segment to the downstream water segment in each pair of adjacent water segments can be determined based on the hydraulic disturbance of the upstream water segment to the downstream water segment within each pair of adjacent water segments and the biological purification limitations of the upstream water segment in each pair of adjacent water segments; then, based on the water quality disturbance of the upstream water segment to the downstream water segment in each pair of adjacent water segments and the biological purification limitations of the downstream water segment within each pair of adjacent water segments, the interference effect of the other water segment on the biochemical purification limitations of the target water segment can be determined.

[0093] It should be understood that the higher the biological purification limitation of the upstream water section, the greater the water quality disturbance of the upstream water section to the downstream water section.

[0094] Optionally, the water quality disturbance of the upstream water segment to the downstream water segment in an adjacent water segment satisfies the following formula:

[0095]

[0096] in, Indicates adjacent water sections Middle and upper reaches of the waters For downstream water section Water quality disturbance, Indicates the upstream water section The limitations of biological purification Indicates adjacent water sections Middle and upper reaches of the waters For downstream water section Hydraulic interference, This represents the maximum and minimum value normalization function. This represents the normalized result for all water quality disturbances to adjacent water segments.

[0097] Understandably, when there is significant hydraulic interference between upstream and downstream water sections, the limitations of biological purification in upstream sections will further exacerbate the deterioration of downstream water quality. As water is transported downstream from upstream sections, the accumulation and concentration of pollutants will be more severe, and pollutants cannot be removed in a timely and effective manner. This results in a continuous impact on the water quality of downstream sections, potentially leading to eutrophication, hypoxia, or other negative environmental effects. Therefore, by comprehensively considering both the hydraulic interference between upstream and downstream water sections and the limitations of biological purification in upstream sections, the water quality interference of upstream sections on downstream sections can be accurately determined.

[0098] In one alternative implementation, after determining the water quality disturbance of the upstream water segment to the downstream water segment in each pair of adjacent water segments, the disturbance impact of each pair of adjacent water segments can be determined by multiplying the water quality disturbance of the upstream water segment to the downstream water segment in each pair of adjacent water segments with the biological purification limitation of the downstream water segment in each pair of adjacent water segments; then, based on the sum of the disturbance impacts of each pair of adjacent water segments, the disturbance impact of the other water segments on the biochemical purification limitation of the target water segment can be determined.

[0099] It is understandable that the downstream water segment in each pair of adjacent water segments also has its own biological purification limitations. Therefore, based on the water quality disturbance of the upstream water segment to the downstream water segment and the biological purification limitations of the downstream water segment, the biological purification limitations of the downstream water segment can be expanded or reduced to obtain the overall disturbance impact of the adjacent water segments.

[0100] It should be understood that the overall disturbance impact of an adjacent water segment is the disturbance impact of that adjacent water segment on the downstream waters of that adjacent water segment.

[0101] It is understandable that these multiple pairs of adjacent water segments are all upstream water segments of the target water segment. Therefore, the superposition of the interference effects of these multiple adjacent water segments constitutes the interference effect of the other water segments on the biological purification limitations of the target water segment.

[0102] Optionally, the interference of other water sections on the biological purification limitations of the target water section satisfies the following formula:

[0103]

[0104] in, Indicates the relationship between other water segments and the target water segment. The limitations of biological purification and the interference effects Indicates the first For the upstream water section of the adjacent water section For downstream water section Water quality disturbance, Indicates the target water area The number of adjacent water segments in other water segments Indicates the downstream water section The limitations of biological purification Indicates the target water area The upstream For adjacent water sections, Indicates the first The impact of interference on adjacent water sections This represents the sum of the disturbance effects of each pair of adjacent water segments in other water segments. This represents the maximum and minimum normalization functions.

[0105] Understandably, in a water system, the health of water quality is influenced not only by the purification capacity of a single water segment but also by the combined effects of its upstream segments. When an upstream segment significantly impacts downstream water quality, it indicates a high concentration of pollutants, potentially leading to a significant deterioration in downstream water quality. If the downstream segment's biological purification capabilities are limited, meaning its pollutant removal efficiency is low, this exacerbates the deterioration. In such cases, the configuration of other water segments has a more significant impact on a single segment, as they may not adequately compensate for the inadequacy of downstream biological purification. For example, if purification measures in other water segments fail to improve overall water flow quality or have limited pollutant removal, the burden on downstream segments will further increase, impacting their ecological functions.

[0106] In this embodiment, the water quality interference of the upstream water segment to the downstream water segment in each pair of adjacent water segments is determined. Then, combined with the biological purification limitations of the downstream water segment itself, the interference impact of each pair of adjacent water segments is obtained. Finally, the interference impact of each pair of adjacent water segments is superimposed to obtain the interference impact of other water segments on the biological purification limitations of the target water segment. This allows for an accurate assessment of the total impact of other water segments on the target water segment.

[0107] S203. Based on the interference of other water sections on the biological purification limitations of the target water section and the biological purification limitations of the target water section, the original purification unit ratio of the target water section is adjusted to obtain the adjusted purification unit ratio.

[0108] Understandably, the greater the interference of other water sections with the biological purification limitations of the target water section, the greater the external pressure on the ecological environment of the target water section, and the worse the purification capacity of the target water section. In this case, the proportion of deep purification units in the target water section should be further increased.

[0109] In one alternative implementation, the adjusted purification unit ratio can be determined based on the product of the interference of other water segments on the biochemical purification limitations of the target water segment, the biological purification limitations of the target water segment, and the original purification unit ratio of the target water segment.

[0110] Understandably, when the interference of other water segments with the biochemical purification limitations of the target water segment, or when the biological purification limitations of the target water segment are less than 1, hyperparameters can be set to adjust the interference of other water segments with the biochemical purification limitations of the target water segment, or the biological purification limitations of the target water segment, so that they are greater than 1.

[0111] Optionally, the adjusted ratio of purification units satisfies the following formula:

[0112]

[0113] in, This indicates the adjusted proportion of the purification units. Indicates the relationship between other water segments and the target water segment. The limitations of biological purification and the interference effects For hyperparameters, Indicates the target water area The limitations of biological purification Indicates the target water area The original purification unit ratio.

[0114] It should be understood that The purpose is to make as well as Greater than 1, because as well as All values ​​are greater than 1. Therefore, the proportion of deep purification units is higher in the adjusted purification unit ratio, and the interference of other water sections on the biological purification limitations of the target water section, as well as the biological purification limitations of the target water section, are all positively correlated.

[0115] For example, The value can be 1.

[0116] In this embodiment, when other water sections interfere with the target water section, it indicates that the biological purification unit in the target water section cannot effectively cope with the pollutant load from the upstream water section, and the water quality may deteriorate. Based on the monitoring data of these other water sections, the interference effect of these other water sections on the biological purification limitations of the target water section is determined. Furthermore, based on this interference effect, the proportion of purification units in the target water section is adjusted to further increase the proportion of deep purification units. Since advanced oxidation and membrane filtration substances in deep purification units have a stronger ability to remove pollutants, they can provide additional purification effects despite the limitations of the biological purification units. By increasing the proportion of deep purification units, the pollutant removal mechanism of the water body can be changed, water purification efficiency can be improved, and a more solid guarantee for the ecological health of the water body can be provided.

[0117] In summary, the water pollution ecological environment treatment method provided in this application first adjusts the proportion of the original purification units by recognizing the limitations of a single water biological purification unit. Then, based on other water sections, a dynamic treatment system is collaboratively established. Finally, considering the mutual influence between water sections, corresponding treatment units are rationally configured for different water sections to achieve the optimal treatment effect for water pollution ecological environment. Compared to existing technologies that directly arrange different purification units based on the specific pollution situation of each water section without fully considering the limitations of biological purification units, this method can significantly improve water purification efficiency.

[0118] Specifically, the core of this application's embodiments lies in eliminating the limitations of biological purification units. The method involves increasing the proportion of deep purification units for water segments with high biological purification limitations. First, by analyzing the correlation between changes in environmental factors and biological purification, the impact of each environmental factor on biological purification capacity is determined. Then, based on environmental changes, the biological purification limitations of each water segment are initially obtained to yield preliminary optimal unit configuration results. Next, starting from the upstream water segment of each segment, the impact of water quality in adjacent water segments on downstream water segments under hydraulic disturbances is assessed. The interference effects of other water segment configuration results on the limitations of biological purification units in a single water segment are cumulatively evaluated. Finally, if significant interference from other water segments and high biological purification limitations are found, the proportion of deep purification units should be appropriately increased to achieve optimal unit configuration.

[0123] Configuration module 302 is also used to determine the limitations of biological purification in the target water segment based on the limited impact of each environmental factor.

[0124] The configuration module 302 is also used to adjust the original purification unit ratio of the target water segment based on the biological purification limitations of the target water segment, so as to obtain the adjusted purification unit ratio.
