[0046] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the drawings of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0047] Agricultural non-point source pollution refers to the nitrogen, phosphorus, organic matter and other nutrients produced in the agricultural production process due to the irrational use of chemical inputs such as fertilizers, agricultural and mulch films, and the untimely or improper treatment of livestock and aquaculture waste, crop straw, etc., which, driven by rainfall and topography, accumulate excessively in the soil or enter rivers with surface and underground runoff and soil erosion as carriers, causing pollution to the ecological environment. Traditional agricultural non-point source pollution load assessments or governance effectiveness assessments mostly rely on the calculation of pollutant generation and emissions, rather than the actual total amount of pollutants in the water, and cannot effectively respond to complex pollution sources and sudden pollution incidents. It is difficult to control according to the load. There are also some solutions in the existing technology that detect river water quality and then control surface pollution. However, the existing solutions still have significant defects. For example, the existing solutions usually use fixed pollution thresholds as the standard for early warning, fail to adopt flexible pollution assessment methods for different river basins and different water quality conditions, and cannot dynamically adjust the control strategy according to specific water body load targets. Secondly, there is a lack of support for comprehensive control measures. Traditional systems often lack precise control measures for different degrees of pollution. Especially when the pollution sources are complex and the control measures are diverse, the system's response strategy lacks pertinence, and it is impossible to track the control progress in real time and provide effective optimization solutions.

[0048] Based on this, this application provides the following solution, which can solve the shortcomings of the existing system in pollution assessment, control strategy adjustment and real-time tracking through dynamic pollution load assessment and precise comprehensive control measures.

[0049] Figure 1 This is one of the flow charts of the river water pollution early warning method provided by the embodiment of the present invention.

[0050] like Figure 1 As shown, this embodiment provides a river water pollution early warning method, including:

[0051] Step 101, obtaining water quality parameters of the river to be treated;

[0052] Among them, the rivers to be treated can be rivers that have been confirmed to suffer from agricultural non-point source pollution and are to be subjected to pollution treatment, or rivers to be subjected to pollution detection. Water quality parameters may include parameters such as river flow, water level, pollutant concentration, pollutant emissions, and water inflow coefficient. The pollutant emissions may refer to the content of pollutants generated by the pollution source, and the water inflow system may refer to the proportion of pollutants generated by the source entering the river. The above data can all be determined based on existing technologies.

[0053] In actual applications, there may be many kinds of pollutants in the river. The above-mentioned pollutant concentrations can be analyzed separately for each pollutant, and then each pollutant can be treated separately.

[0054] Step 102, determining the content of pollutants to be removed from the river to be treated based on the water quality parameters of the river to be treated and a set threshold, wherein the set threshold represents a target value of the water quality parameters of the river to be treated;

[0055] In actual applications, the threshold value can be set based on the requirements of the national surface water assessment section. The national surface water assessment section is referred to as the national assessment section, which is subordinate to the evaluation, assessment, and ranking monitoring section (point) in the national surface water environment monitoring network. It focuses on improving water environment quality and meets current environmental management needs such as basin water pollution prevention and control target task assessment and urban water environment quality ranking. The set threshold value determined in this embodiment can be 9.5 mg / L, that is, each liter of water contains a maximum of 9.5 mg of pollutants. If the river to be treated exceeds this standard, it needs to be treated.

[0056] Step 103: issuing an early warning of the pollution degree of the river to be treated based on the content of pollutants to be removed from the river to be treated.

[0057] In practice, the content of pollutants to be removed can be determined based on the above-mentioned set threshold. After purifying part of the pollutants from the river to be treated according to the content of pollutants to be removed, the pollutant concentration parameters of the river are made lower than the set threshold.

[0058] After the early warning is completed, the pollution control of the river can be carried out based on the content of pollutants to be removed from the river to be treated. In practical applications, the methods of river pollution control can at least include process interception, source control and buffer measures, among which process interception refers to intercepting pollutants in the process of entering the river through certain technical means or facilities to prevent them from entering the water body. Specific methods include: constructing wetland systems, sedimentation tanks / trash dams and ecological ditches. Constructing wetland systems is to establish artificial wetlands or restore natural wetlands between farmland and rivers, and use wetland plants and microorganisms to degrade, absorb and fix nutrients such as nitrogen and phosphorus to reduce their flow into rivers; constructing sedimentation tanks / trash dams is to set up small sedimentation tanks or trash dams at key locations to retain surface runoff carrying sediment and pollutants, allowing larger particles to settle and reduce the pollution load entering the river; ecological ditches are designed to have purification functions. Vegetation that can effectively remove pollutants is planted, and combined with appropriate physical and chemical treatment units, such as sand filter beds, gravel layers, etc., to further reduce pollutant concentrations.

[0059] Source control refers to reducing river pollution by controlling the discharge of pollutants from the source of pollutants. Specific methods include: precision fertilization, optimized irrigation methods, green pest control, and livestock and poultry waste management. Precision fertilization refers to the promotion of soil testing and formula fertilization technology, and the rational application of chemical fertilizers according to soil fertility and crop needs to avoid nutrient loss caused by excessive fertilization; optimized irrigation methods refer to the use of water-saving irrigation technology and equipment, such as drip irrigation and sprinkler irrigation, to improve water utilization and reduce fertilizer loss caused by excessive irrigation; green pest control: encourage the use of non-chemical means such as biological control and physical control to control pests and diseases, reduce the use of pesticides and their environmental risks; livestock and poultry waste management refers to strengthening the internal management of farms and external emission supervision to ensure that feces and sewage are properly treated, such as producing biogas as clean energy through anaerobic fermentation, and using solid residues for organic fertilizer production.

[0060] Buffer measures refer to setting up certain buffer zones or protection zones on both sides of a river or in the surrounding areas to reduce the direct impact of pollutants on the river. Specific methods include: setting up vegetation buffer zones, restoring natural landform features, and adjusting land use planning. The establishment of vegetation buffer zones can form buffer zones by planting trees, grass or other vegetation along the river bank. The root systems of these plants can fix the soil and prevent erosion. At the same time, they can also filter and absorb pollutants flowing into the river from land. Restoring natural landform features can be to try to maintain or restore the original topographic and landform features around the river, such as alternating layouts of curved river channels, shallows and deep pools, etc., to increase the length of the water flow path, extend the residence time of pollutants, and promote the natural purification process. Land use planning adjustments can be to reasonably plan the relationship between agricultural land and other types of land, such as restricting agricultural activities with high pollution risks near rivers, or planning a certain width of non-agricultural areas as ecological barriers.

[0061] In practical applications, the choice of treatment method can be based on the degree of pollution of the river.

[0062] In the river water quality pollution early warning method provided in the present embodiment, the water quality parameters of the river to be treated can be first collected, and the current water quality of the river to be treated can be determined based on the water quality parameters, and further combined with the set water quality threshold, the content of pollutants to be eliminated in the river to be treated can be determined. Furthermore, an early warning of the pollution degree can be given for different river basins based on the content of pollutants to be eliminated. Flexible pollution assessment methods can be used for different water quality conditions, which can provide more accurate early warnings on the pollution degree of the river, and then flexible pollution control methods can be used. The "tailor-made" control method can significantly improve the control effect of river water quality.

[0063] In an exemplary embodiment, the water quality parameter of the river to be treated includes the flow rate of the river to be treated;

[0064] The step of determining the content of pollutants to be removed from the river to be treated based on the water quality parameters of the river to be treated and the set threshold value includes:

[0065] The content of pollutants to be removed from the river to be treated is determined based on the flow rate of the river to be treated and a set threshold.

[0066] In practical applications, the flow rate of the river to be managed and the set threshold value can be multiplied to obtain the content of pollutants to be eliminated from the river to be managed. Specifically, the unit of measurement of the flow rate can be L / day (d), that is, the amount of water per day, and the unit of measurement of the set threshold value is mg / L. The unit of measurement of the product of the two is mg / d, or kg / d, which means the content of pollutants that the river can withstand every day. Pollutants below this content can be purified by the river's own purification ability. If it exceeds this content, artificial management is required.

[0067] In an exemplary embodiment, the content of pollutants to be removed from the river to be treated based on the flow of the river to be treated and a set threshold value includes:

[0068] Determining a pollutant target value of the river to be treated based on the flow of the river to be treated and the set threshold value;

[0069] Based on the pollutant content of the river to be treated and the pollutant target value, the content of pollutants to be removed from the river to be treated is determined, wherein the pollutant content of the river to be treated is determined based on the water quality parameters of the river to be treated.

[0070] In this embodiment, after the pollutant target value is calculated by multiplying the river flow rate and the set threshold value, the current pollutant concentration of the river to be treated can be determined directly based on the water quality parameters of the river to be treated. In this way, the current daily pollutant content of the river to be treated can also be calculated by multiplying the current pollutant concentration and the river flow rate. The content of pollutants to be eliminated in the river to be treated can be obtained by subtracting the current value from the pollutant target value.

[0071] In an exemplary embodiment, the content of pollutants to be removed from the river to be treated based on the water quality parameters of the river to be treated and the set threshold value includes:

[0072] Determining the pollutant content of the mainstream of the river to be treated based on the water quality parameters;

[0073] If the pollutant content of the mainstream of the river to be treated exceeds a set threshold, the pollutant content of each tributary of the river to be treated is determined based on the water quality parameters;

[0074] Based on the pollutant content of the tributary streams and the set threshold value, the content of the pollutants to be eliminated is determined for each of the tributary streams.

[0075] For a river, it often has a mainstream and several tributaries. The water of the tributaries converges into the mainstream, and the tributaries will also widen the affected area of ​​the river and bring more pollutants to the river. Therefore, when treating pollutants in a river, it is necessary to consider the mainstream and tributaries of the river, issue separate warnings for the mainstream and tributaries of the river, and adopt different pollutant treatment methods. Specifically, in this embodiment, it is possible to first determine whether the pollutant content of the mainstream exceeds the standard through water quality parameters. If it does not exceed the standard, it means that the health risk of the river is low, and no pollution warning may be issued first. If it exceeds the standard, it means that the pollutant content of at least one tributary seriously exceeds the standard. At this time, the pollutant content of each tributary may be tested, and pollution warnings may be issued for each tributary separately, and each tributary may be treated separately.

[0076] In this embodiment, by issuing separate warnings for each tributary of the river to be managed, the pollution control effect of treating the symptoms and the root causes can be achieved, and the pollution warning and management effects are better.

[0077] In an exemplary embodiment, the step of determining the content of pollutants to be removed for each of the tributaries based on the pollutant content of the tributaries and the set threshold value includes:

[0078] Comparing the pollutant content of each of the tributaries with the set threshold value, determining the tributaries to be treated, wherein the pollutant content of the tributaries to be treated exceeds the set threshold value;

[0079] Determining the water quality parameters of the tributary to be treated based on the water quality parameters of the river to be treated;

[0080] Determining a pollutant target value of the tributary to be treated based on the water quality parameters of the tributary to be treated and the set threshold value;

[0081] Based on the pollutant content of the tributary to be treated and the pollutant target value, the content of the pollutants to be eliminated in the tributary to be treated is determined.

[0082] During implementation, the pollutant concentration of each tributary of the river to be treated can be compared with the set threshold value. If it exceeds the set threshold, the corresponding tributary is determined to be the tributary to be treated. Furthermore, the pollutant target value, that is, the target value, of the tributary to be treated can be determined based on the pollutant concentration of the tributary to be treated and the set threshold value.

[0083] In an exemplary embodiment, the water quality parameter of the tributary to be treated includes the flow rate of the tributary to be treated;

[0084] The step of determining the pollutant target value of the tributary to be treated based on the water quality parameter of the tributary to be treated and the set threshold value includes:

[0085] Based on the flow rate of the tributary to be treated and the set threshold, a pollutant target value of the tributary to be treated is determined.

[0086] In practical applications, flow data needs to be collected for each tributary of the river to be managed. Consistent with the above embodiment, for each tributary, the pollutant target value of the tributary to be managed can be determined based on the product of the flow rate and the set threshold. In this embodiment, the unit of measurement of the flow rate can be L / day (d), that is, the amount of water per day. The unit of measurement of the set threshold is mg / L, and the unit of measurement of the product of the two is mg / d, or kg / d. The meaning of the representation is the content of pollutants that the tributary to be managed can withstand every day. Pollutants below this content can be purified by the purification capacity of the river tributary itself. If it exceeds this content, artificial management is required.

[0087] In an exemplary embodiment, the water quality parameter includes a river entry coefficient, which represents the transmission efficiency of pollutants in the river to be treated;

[0088] The method of providing an early warning of the pollution degree of the river to be treated based on the content of pollutants to be removed from the river to be treated includes:

[0089] Based on the content of pollutants to be removed from the river to be treated and the river inflow coefficient, an early warning is given to the pollution degree of the river to be treated.

[0090] In practical applications, if the inflow coefficient of a river basin or a tributary exceeds the average level of the entire river basin to be managed, it means that the pollution of the river basin or the tributary is relatively serious, and it can be given priority warning and management.

[0091] In an exemplary embodiment, the early warning of the pollution degree of the river to be treated based on the content of pollutants to be removed from the river to be treated includes:

[0092] Determining the warning order of the river to be treated based on the content of pollutants to be removed in the river to be treated;

[0093] An early warning is issued to the river to be managed based on the early warning sequence.

[0094] In this implementation, the pollution severity of the river to be treated can be determined by the content of pollutants to be removed in the river to be treated, as well as the pollution degree of each river basin and each tributary of the river to be treated. The order of treatment is determined according to the degree of pollution, and early warning and treatment are carried out first in the areas with more serious pollution. This can improve the pollution early warning and treatment efficiency of the river from the overall perspective of the river.

[0095] Figure 2 This is the second flow chart of the river water pollution early warning method provided by the embodiment of the present invention.

[0096] Combine the following Figure 2 , taking a specific embodiment as an example to illustrate the river water quality pollution early warning method provided by the present application, comprising the following steps.

[0097] Collect basic information of the river basin to be managed, such as flow, water level, flow rate, etc. The ecological environment department provides water quality monitoring information. Through connecting to the national surface water environment quality monitoring network, collect water quality parameters such as pH value, dissolved oxygen, biochemical oxygen demand (BOD), chemical oxygen demand (COD), ammonia nitrogen, total phosphorus, total nitrogen, etc., and estimate the sampling days for each target pollutant based on the hydrological and water quality monitoring data to obtain the daily load data corresponding to the minimum sampling days. The inflow coefficient is determined based on the on-site survey data. Manual input is used as a supplementary input method for production data and test data.

[0098] In this embodiment, a pollutant in a certain river basin is used as an example. The main river has four tributaries, namely, tributary 1, tributary 2, tributary 3 and tributary 4. The mainstream flow of the river is 10m 3 / d, the pollutant concentration is 10mg / L, the pollution load is 100kg / d, the discharge is 260kg / d, the water inflow coefficient is 0.39, and the target water quality of the national surface water assessment section of the main river is 9.5mg / L, that is, the preset threshold is 9.5mg / L. Among them, the flow of tributary 1 is 3m 3 / d, the pollutant concentration is 11mg / L, the pollution load is 33kg / d, the discharge is 88kg / d, and the water inlet coefficient is 0.38; the flow of tributary 2 is 2m 3 / d, the pollutant concentration is 11mg / L, the pollution load is 22kg / d, the discharge is 31kg / d, and the water inlet coefficient is 0.67; the flow of tributary 3 is 3m 3 / d, pollutant concentration is 9±0.1mg / L, pollution load is 27kg / d, discharge is 90kg / d, water inlet coefficient is 0.3; tributary 4 flow is 2m 3 / d, the pollutant concentration is 9±4mg / L, the pollution load is 18kg / d, the emission is 51kg / d, and the water entry coefficient is 0.35.

[0099] After that, the pollution of the main river was evaluated. First, the water quality compliance of the basin was evaluated. The target water quality of the national surface water assessment section of the main river was 9.5mg / L, while the mainstream water quality of the river to be treated was 10mg / L, which was judged to be substandard. It was necessary to further judge the load compliance and confirm the load reduction target. The load target is the integral of the product of the tributary flow and the water quality target of the basin, and the load reduction target is the content of pollutants that need to be removed to achieve the water quality target.

[0100]

[0101] Where:

[0102] M——River load, indicating the total amount of pollutants in the environmental medium, in kg / d;

[0103] Ci——the concentration of the i-th pollutant in the river, in mg / L;

[0104] Q——River flow, in m 3 / d.

[0105] Therefore, the main river load is 100kg / d, the target load is 95kg / d, and the load is judged to be substandard. The load reduction target is 5, which is classified as a high-risk level. Further judgment is made on whether the inflow coefficient exceeds the average level of the entire basin. The main river inflow coefficient is 0.39, and the average inflow coefficient is 0.418, which is judged to be up to standard. Subsequent source control will be adopted.

[0106] Judging from the results of the pollution level assessment module, it is necessary to take source control measures for the main river, so the pollution level of the tributaries is further assessed. The water quality target of the tributaries refers to the target water quality of 9.5mg / L for the national surface water assessment section of the main river. According to the compliance analysis of the pollutant concentration of the tributaries, the concentration of tributary 3 is 9±0.1mg / L, which is judged to be up to standard and classified as a low risk level; the concentrations of tributaries 1, 2, and 4 are 11mg / L, 11mg / L, and 9±4mg / L respectively, which are judged to be not up to standard, and it is necessary to further judge the compliance of the load and confirm the load reduction target.

[0107] The load target is the integral of the product of the tributary flow and the water quality target of the basin, and the load reduction target is the content of pollutants that need to be removed to achieve the water quality target. The load target of tributary 1 is 28.5kg / d, and the current load is 33kg / d. It is judged that the load does not meet the standard. The load reduction target is 4.5kg / d, which is classified as a high-risk level; the load target of tributary 2 is 19kg / d, and the current load is 22kg / d. It is judged that the load does not meet the standard. The load reduction target is 3kg / d, which is classified as a high-risk level; the load target of tributary 4 is 18kg / d, and the current load is 18kg / d. It is judged that the load meets the standard, and there are measures for time periods, which is classified as a medium-risk level, and buffer measures will be used for subsequent management.

[0108] Further determine whether the inflow coefficients of tributaries 1 and 2 exceed the average level of the entire basin, and select load reduction technology. The average level of this basin is 0.39 for the main river inflow water body, and 0.38 for tributary 1, which is judged to be up to standard, and source control will be adopted in the future; the inflow coefficient of tributary 2 is 0.69, which is judged to be not up to standard, and pathway blocking measures will be adopted in the future.

[0109] Through the pollution degree assessment module and early warning module, each river basin can be divided into three risk levels: low, medium and high. According to the urgency and effectiveness of governance in different river basins, the system will take corresponding buffer measures, source control measures and process interception measures. At the same time, key parameters in the governance process will be updated regularly and fed back to the parameter acquisition and display module to ensure the real-time and accuracy of governance measures.

[0110] The above embodiments have the following beneficial effects:

[0111] Through basin production surveys and detection parameter analysis, dynamic monitoring and comprehensive assessment of water resource pollution are achieved, which can capture changes in water quality and pollution load in real time, providing a scientific basis for pollution source control;

[0112] Through the graded assessment of the pollution degree of the river basin, corresponding governance strategies are provided according to different risk levels, and the parameter changes in the governance process are tracked in real time, thus optimizing the implementation of pollution control measures;

[0113] It has a high level of intelligence and automation, reduces human intervention, can track the progress of pollution control in real time and provide flexible response measures, improves control efficiency and emergency response capabilities, and helps achieve sustainable management of water resources.

[0114] The river water pollution control system provided by the present invention is described below. The river water pollution control system described below and the river water pollution early warning method described above can be referenced to each other.

[0115] FIG. 3 is a schematic diagram of the structure of a river water pollution control system provided by an embodiment of the present invention.

[0116] like Figure 3 As shown, the river water pollution control system provided in this embodiment includes:

[0117] A data acquisition unit 301 is used to acquire water quality parameters of the river to be treated;

[0118] A data processing unit 302 is used to determine the content of pollutants to be removed from the river to be treated based on the water quality parameters of the river to be treated and a set threshold, wherein the set threshold represents a target value of the water quality parameters of the river to be treated;

[0119] The pollution control unit 303 is used to warn the pollution degree of the river to be treated based on the content of pollutants to be removed from the river to be treated.

[0120] Specifically, the data acquisition unit 301 is used to collect and update key parameters of water resources in real time, including but not limited to flow, water level, water quality and other data, and display this information in a clear visual format to provide instant data support for the monitoring system.

[0121] The data acquisition unit 301 can be manually input by the user into the basic production data collected from the survey and the reported detection data. In addition, the unit also automatically obtains the necessary monitoring parameters through data docking with the monitoring system and displays these parameters intuitively.

[0122] The data processing unit 302 is specifically used to obtain the parameters fed back by the display module by analyzing the parameters, quantitatively evaluate the degree of pollution of water resources according to the standards, determine the pollution level of the water body, and provide a basis for water quality improvement measures.

[0123] The data processing unit 302 can make parameter requirements to the data acquisition unit 301, and perform production intensity calculation and water quality pollution assessment based on the fed-back parameters. The production intensity is calculated by production volume and environmental statistical coefficients; the pollutant flux is calculated based on water quality exceeding the standard when there is no hydrological data, and is calculated by the integral method when there is hydrological data.

[0124] If the pollution level assessment result shows that no treatment is needed or the pollution level is not in the treatment stage, the regional parameters need to be updated regularly. On the contrary, when the river to be treated is being treated, it is ensured that the relevant parameters in the treatment process are reflected in the data acquisition unit 301 in a timely manner.

[0125] The data processing unit 302 covers three key steps: first, assessing river water quality; second, assessing tributary loads; and finally, selecting load reduction technology.

[0126] Furthermore, the assessment of river water quality is performed by determining whether the water quality exceeds the standard. If the water quality does not exceed the standard, it is classified as a low risk level; if the water quality exceeds the standard, it proceeds to the step of assessing the tributary load.

[0127] Furthermore, the assessment of tributary load is performed by determining whether the load exceeds the standard. If the load does not exceed the standard, it is classified as a medium risk level; if the load exceeds the standard, it is classified as a high risk level. The load target is the total amount of pollutants required to achieve the water quality target, which is obtained by calculating the integral of the product of the tributary flow and the water quality target of the basin. The load reduction target is the difference between the load target and the current basin load.

[0128] Furthermore, the load reduction technology is selected by judging whether the river inflow coefficient exceeds the average level of the whole basin. If the river inflow coefficient exceeds the average level, process interception measures are implemented first; if not, source control measures are implemented.

[0129] Furthermore, when the basin is classified as a medium risk level, it is necessary to further determine whether there are measures for the time period. If such measures exist, buffer measures are selected. If not, it is necessary to further determine whether the river inflow coefficient exceeds the average level of the entire basin and select other load reduction technologies.

[0130] In an exemplary embodiment, the water quality parameters of the river to be treated include the flow rate of the river to be treated, and the data processing unit 302 is further used to determine the content of pollutants to be removed from the river to be treated based on the flow rate of the river to be treated and a set threshold.

[0131] In an exemplary embodiment, the data processing unit 302 is further used to: determine the pollutant target value of the river to be treated based on the flow of the river to be treated and the set threshold;

[0132] Based on the pollutant content of the river to be treated and the pollutant target value, the content of pollutants to be removed from the river to be treated is determined, wherein the pollutant content of the river to be treated is determined based on the water quality parameters of the river to be treated.

[0133] In an exemplary embodiment, the data processing unit 302 is further used to: determine the pollutant content of the mainstream of the river to be treated based on the water quality parameters;

[0134] If the pollutant content of the mainstream of the river to be treated exceeds a set threshold, the pollutant content of each tributary of the river to be treated is determined based on the water quality parameters;

[0135] Based on the pollutant content of the tributary streams and the set threshold value, the content of the pollutants to be eliminated is determined for each of the tributary streams.

[0136] In an exemplary embodiment, the data processing unit 302 is further used to: compare the pollutant content of each of the tributaries with the set threshold value, determine the tributaries to be treated, and the pollutant content of the tributaries to be treated exceeds the set threshold value;

[0137] Determining the water quality parameters of the tributary to be treated based on the water quality parameters of the river to be treated;

[0138] Determining a pollutant target value of the tributary to be treated based on the water quality parameters of the tributary to be treated and the set threshold value;

[0139] Based on the pollutant content of the tributary to be treated and the pollutant target value, the content of the pollutants to be eliminated in the tributary to be treated is determined.

[0140] In an exemplary embodiment, the water quality parameters of the tributary to be treated include the flow rate of the tributary to be treated, and the data processing unit 302 is also used to determine the pollutant target value of the tributary to be treated based on the flow rate of the tributary to be treated and the set threshold.

[0141] In an exemplary embodiment, the water quality parameter includes a river entry coefficient, which represents the transmission efficiency of pollutants in the river to be treated. The pollution treatment unit 303 is further used for:

[0142] Based on the content of pollutants to be removed from the river to be treated and the river inflow coefficient, an early warning is given to the pollution degree of the river to be treated.

[0144] An early warning is issued to the river to be managed based on the early warning sequence.
