[0062] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0063] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure or characteristic that may be included in at least one implementation of the present invention. The phrase "in a preferred embodiment" that appears in different places in this specification does not refer to the same embodiment, nor is it a separate or selective embodiment that is mutually exclusive with other embodiments.

[0064] Secondly, the present invention is described in detail in conjunction with schematic diagrams. When describing the embodiments of the present invention in detail, for the convenience of explanation, the schematic diagrams are only examples and should not limit the scope of protection of the present invention.

[0065] Please refer to the attached Figure 1 As shown, an intelligent purification method for water purification is provided, comprising:

[0066] S1. Obtain real-time water quality information, and determine whether the water quality meets the preset conditions based on the real-time water quality information. If the real-time water quality information does not meet the preset conditions, the water quality is determined to be polluted and marked as polluted water quality information;

[0067] S2. Obtain the type of water pollution according to the polluted water quality information, obtain the corresponding water purification plan according to the water pollution type, and purify the polluted water according to the water purification plan to obtain purified water quality information;

[0068] S3, returning the purified water quality information as real-time water quality information to the step of judging whether the water quality meets the preset conditions according to the real-time water quality information; if the purified water quality information does not meet the preset conditions, it is judged that the purified water quality information has water pollution and is marked as residual polluted water quality information;

[0069] S4. Return the remaining polluted water quality information as real-time water quality information to the table for obtaining water quality pollution types, obtain the water quality pollution type of the polluted water quality according to the polluted water quality information, and return the purified water quality information as real-time water quality information to the step of judging whether the water quality meets the preset conditions according to the real-time water quality information, until it is determined that the water quality is not polluted.

[0070] As in the above steps S1 to S4, real-time water quality information is obtained through sensors or other monitoring equipment, including water temperature, pH value, chemical oxygen demand (COD), total phosphorus (TP), ammonia nitrogen (NH3-N) and heavy metal content. These parameters are used to comprehensively evaluate the water quality. The real-time water quality information is compared with the preset standard parameters. If all parameters are within the standard range, it is determined that the water quality is not polluted and can be discharged from the water body. If any parameter exceeds the preset range, it is determined that the water quality is polluted and the information is marked as polluted water quality information. According to the marked polluted water quality information, the water quality is determined through the pre-established water quality pollution type table. The specific type of pollution, according to the determined type of pollution, select the corresponding purification plan, execute the purification plan, treat the polluted water quality, and obtain the treated water quality information, that is, the purified water quality information, and compare the purified water quality information with the preset conditions again. If it meets the standards, stop purification and discharge the water body. If it still does not meet the standards, it is determined as residual polluted water quality information and re-marked to enter the next round of processing cycle. The residual polluted water quality information will continue to be type determined and purified. This cycle continues until the water quality meets the preset conditions to ensure that the final discharged water meets the safety standards. For example, assuming Collect data in real time, and find that COD, TP and NH3-N exceed the standard in the wastewater discharged by a certain factory. Determine that the water quality is polluted, query the pollution type table, determine that it is organic matter, phosphorus and ammonia nitrogen pollution, and select the corresponding purification plan, such as biodegradation method to treat COD, ion exchange method to treat ammonia nitrogen, and test the water quality again after treatment. If COD and NH3-N still exceed the standard, continue to select the optimized plan for further treatment, and repeat the cycle until the water quality meets the standard. It is determined that the water quality is not polluted, stop purification and discharge the water body. It can obtain and process water quality information in real time, ensure the timeliness and accuracy of monitoring, dynamically adjust the purification plan, and adjust the water quality according to the specific pollution. The best treatment method is selected for each pollution type to improve purification efficiency. Special purification schemes are adopted for different types of pollution to ensure the right medicine is used and the purification effect is significantly improved. Through cyclic purification, residual pollutants are ensured to be thoroughly treated and the final output water quality meets the standards. The whole process is controlled by an intelligent system without human intervention, reducing errors and workload caused by human operation. It automatically determines and switches purification schemes to ensure continuity and stability of operation. Through precise control and efficient treatment, the use of chemical agents is reduced, and the risk of secondary pollution to the environment is reduced. It can effectively deal with various complex water pollution problems and protect water resources and the ecological environment.

[0071] The steps of obtaining real-time water quality information, judging whether the water quality meets the preset conditions according to the real-time water quality information, and judging that the water quality is polluted and marking it as polluted water quality information if the real-time water quality information does not meet the preset conditions include:

[0072] S101, obtaining the collection frequency of water quality collection information;

[0073] S102, determining a collection duration according to a collection frequency, and establishing multiple collection nodes according to the collection duration;

[0074] S103, collecting real-time water quality information in each collection node;

[0075] S104. Determine whether the water quality meets the preset conditions based on the real-time water quality information. If the real-time water quality information does not meet the preset conditions, determine that the water quality is polluted and mark it as polluted water quality information.

[0076] It should be noted that the real-time water quality information includes water temperature parameters, pH value parameters, chemical oxygen demand COD parameters, total phosphorus TP parameters, ammonia nitrogen NH3-N parameters and heavy metal parameters.

[0077] As in the above steps S101 to S104, first, determine the frequency of water quality information collection. The collection frequency can be set according to the specific application scenario and the speed of water quality change, for example, once an hour or once a minute. According to the set collection frequency, determine the time period required for each data collection, that is, the collection duration. During the collection duration, establish multiple collection nodes. These nodes are time intervals and are used to collect data multiple times during the entire duration to ensure the comprehensiveness and continuity of the collection. For example, within a one-hour collection duration, a collection node can be set every ten minutes. At each collection node, real-time water quality information is collected through sensors and other equipment, including water temperature, pH value, chemical oxygen demand (COD), total phosphorus (TP), ammonia nitrogen (NH3-N) and heavy metal parameters, etc. The real-time water quality information is compared with the preset standard parameters. If all parameters are within the standard range, it is determined that the water quality is not polluted and can be discharged from the water body. If any parameter exceeds the preset range, it is determined that the water quality is polluted. The system can collect water quality information in real time, detect water pollution and mark the information as polluted water quality information. By setting a reasonable collection frequency and collection time, the water quality can be monitored at a high frequency, and the subtle changes in water quality can be captured in time, which improves the sensitivity and accuracy of monitoring. Data collection through multiple collection nodes within the collection time can ensure the comprehensiveness and continuity of water quality information, avoid errors and omissions that may be caused by single-point data, and collect a variety of water quality parameters in real time. It can fully reflect the water body status and provide an accurate and detailed data basis for subsequent water quality assessment and pollution judgment. It can collect and process water quality information in real time. Once abnormal water quality parameters are found, it can respond quickly and take corresponding purification measures to reduce the risk of pollution spread. The collection frequency and collection time can be dynamically adjusted according to the actual water quality changes to adapt to different pollution environments and management needs, improve flexibility and adaptability, and provide a scientific basis for decision-making in real time and continuous water quality data, making water purification measures more accurate and effective, and improving purification effects and resource utilization.

[0078] After the step of collecting real-time water quality information in each collection node, it also includes:

[0079] S10301. Acquire multiple historical real-time water quality parameters and current real-time water quality parameters corresponding to the real-time water quality information;

[0080] S10302. Obtain water quality change trend function;

[0081] S10303, inputting a plurality of historical real-time water quality parameters and a current real-time water quality parameter into a water quality change trend function, and marking the output result as a water quality change trend value;

[0082] S10304, obtaining a standard water quality assessment interval, and determining whether the water quality change trend value is within the standard water quality assessment interval;

[0083] If the water quality change trend value is within the standard water quality assessment range, the water quality change trend is determined to be stable;

[0084] If the water quality change trend value is not within the standard water quality assessment interval and is greater than the upper limit of the standard water quality assessment interval, it is determined that the water quality change trend continues to improve;

[0085] If the water quality change trend value is not within the standard water quality assessment range and is less than the lower limit of the standard water quality assessment range, it is judged that the water quality change trend continues to deteriorate.

[0086] As in the above steps S10301 to S10304, not only the current real-time water quality parameters are collected, but also the real-time water quality parameters of multiple historical moments are collected. These historical data are used to analyze the trend of water quality changes. A water quality change trend function is used. The function is based on a mathematical model or algorithm and can analyze and predict the trend of water quality changes. This may include linear regression, time series analysis and other methods. The water quality change trend function is In the formula, Q represents the water quality change trend value, i represents the number of historical real-time water quality parameters, n represents the total number of historical real-time water quality parameters, and D i Represented as the i-th historical real-time water quality parameter, S dIt is represented as the current historical real-time water quality parameters. The collected multiple historical real-time water quality parameters and the current real-time water quality parameters are input into the water quality change trend function to calculate and output the water quality change trend value. This trend value represents the direction and magnitude of the water quality change. A standard water quality assessment interval is set to determine the normal range of the water quality change trend. If the water quality change trend value is within the standard interval, it means that the water quality change is stable and has not significantly improved or deteriorated. If the water quality change trend value exceeds the upper limit of the standard interval, it means that the water quality continues to improve. If the water quality change trend value is lower than the lower limit of the standard interval, it means that the water quality continues to deteriorate. By analyzing historical data and current data, the water quality change trend can be predicted. This dynamic prediction capability helps to identify potential water quality problems in advance and take preventive measures. The water quality can be evaluated more accurately through the water quality change trend function. The direction and magnitude of change are more comprehensive and in-depth than relying solely on real-time data. It not only focuses on the current water quality status, but also monitors the trend of water quality changes. This trend monitoring helps to timely discover the impact of long-term changes and improve the efficiency of management and purification. If the water quality change trend value shows that the water quality continues to deteriorate, it can be warned in advance and additional purification measures or other intervention measures can be taken to prevent further deterioration of water quality. According to the water quality change trend, the purification strategy can be dynamically adjusted. For example, when the water quality continues to improve, the purification intensity can be appropriately reduced, thereby saving resources and costs. Based on a large amount of historical data and real-time data, it provides scientific, data-driven decision support, improves the scientificity and effectiveness of water quality management, and can better adapt to complex and changeable water quality environments and enhance overall robustness and reliability by continuously monitoring and predicting water quality change trends.

[0087] The steps of judging whether the water quality meets the preset conditions according to the real-time water quality information, and judging that the water quality is polluted and marking it as polluted water quality information if the real-time water quality information does not meet the preset conditions, include:

[0088] S1041. Obtain water pollution assessment thresholds;

[0089] S1042, obtaining corresponding real-time water quality parameters according to the real-time water quality information;

[0090] S1043, determining whether the real-time water quality parameter exceeds the water quality pollution assessment threshold;

[0091] If the real-time water quality parameters exceed the water pollution assessment threshold, the water quality is determined to be polluted and marked as polluted water quality information;

[0092] If the real-time water quality parameters do not exceed the water pollution assessment threshold, the water quality is determined to be unpolluted and the water body is discharged.

[0093] As in the above steps S1041 to S1043, first, the preset water quality pollution assessment thresholds are obtained. These thresholds are usually based on environmental protection standards or specific application requirements, covering multiple parameters such as water temperature, pH value, chemical oxygen demand (COD), total phosphorus (TP), ammonia nitrogen (NH3-N) and heavy metal content. According to the water quality information collected in real time, the corresponding real-time water quality parameters are extracted. These parameters are the specific water quality index values ​​at the current moment. The real-time water quality parameters are compared with the preset water quality pollution assessment thresholds. If any real-time water quality parameter exceeds the corresponding assessment threshold, it is determined that the water quality is polluted, and the information is marked as polluted water quality information. If all real-time water quality parameters do not exceed the assessment threshold, it is determined that the water quality is not polluted and can be safely discharged from the water body. By comparing with the preset threshold, it can be quickly identified whether the water quality is polluted. When pollution is detected, corresponding treatment measures can be taken in time to prevent polluted water from entering the environment or being further used. Multiple specific water quality parameters are used for evaluation, and the judgment results are more accurate, avoiding misjudgment due to abnormal single parameters, improving the reliability of water quality monitoring, and being able to judge water quality conditions in real time and respond in time. Once pollution is found, the purification program can be started quickly to reduce the risk of pollution spread. By setting reasonable assessment thresholds, not only existing pollution can be dealt with, but potential water quality problems can also be prevented to ensure long-term water quality safety. The comparison between real-time water quality parameters and preset thresholds provides a scientific basis, making the decision-making process more transparent and data-driven, improving the scientific nature of water quality management and purification, and the water pollution assessment thresholds can be flexibly adjusted according to different application scenarios and environmental conditions to adapt to different water quality requirements, with high adaptability.

[0094] The steps of obtaining the type of water pollution according to the polluted water quality information, obtaining the corresponding water purification scheme according to the water pollution type, and purifying the polluted water according to the water purification scheme to obtain the purified water quality information include:

[0095] S201, obtaining a water pollution type table, the water pollution type table including multiple water pollution assessment intervals and the water pollution type corresponding to each water pollution assessment interval;

[0096] S202, obtaining polluted water quality parameters according to the polluted water quality information, and obtaining a target water quality pollution assessment interval according to the polluted water quality parameters;

[0097] S203, obtaining a corresponding water pollution type from a water pollution type table according to the target water pollution assessment interval;

[0098] S204. Obtain a corresponding water purification scheme according to the water pollution type, and purify the polluted water according to the water purification scheme to obtain purified water quality information.

[0099] As in the above steps S201 to S204, first, a preset water pollution type table is obtained, which contains multiple water pollution assessment intervals, each interval corresponding to a specific water pollution type, and each assessment interval is usually set based on the range of water quality parameters, such as different COD, TP, NH3-N, heavy metal content, etc. According to the previously marked polluted water quality information, specific polluted water quality parameters are extracted, and these parameters are compared with the assessment intervals in the water pollution type table to determine the target water pollution assessment interval corresponding to the current pollution situation. According to the determined target water pollution assessment interval, the corresponding water pollution type is obtained from the water pollution type table, and the specific water quality parameters are mapped to the specific pollution type to provide a basis for the subsequent purification scheme selection. For example, the water pollution type table is classified according to the Class V water standard of the "Surface Water Environmental Quality Standard GB3838-2002" and the "Urban Wastewater Treatment Plant Pollutant Discharge Standard GB18918-2002" Level A and B, and several key pollutants are selected: chemical oxygen demand COD, total phosphorus TP, and ammonia nitrogen NH3-N as the discrimination criteria;

[0100] When the pollutants are lower than Class V in surface water and higher than Class A in urban sewage discharge, that is, when 40mg / L<COD≤50, 0.4mg / L<TP≤0.5mg / L, 2mg / L<NH3-N≤5mg / L, it is a mild level;

[0101] When the pollutant content is lower than the first level A of urban sewage discharge and higher than the first level B, that is, 50mg / L<COD≤60mg / L, 0.5mg / L<TP≤1mg / L, 5mg / L<NH3-N≤8mg / L, it is a moderate level;

[0102] When heavy metals exceed the standard, and water pollutants are lower than Class V in surface water and higher than Class A in urban sewage discharge, that is, when 40mg / L<COD≤50, 0.4mg / L<TP≤0.5mg / L, 2mg / L<NH3-N≤5mg / L, it is a mild level of heavy metals;

[0103] When heavy metals exceed the standard, and the pollutant content is lower than Class A of urban sewage discharge and higher than Class B, that is, 50mg / L<COD≤60mg / L, 0.5mg / L<TP≤1mg / L, 5mg / L<NH3-N≤8mg / L, it is a moderate level of heavy metals;

[0104] When any heavy metal pollutant in the water exceeds the Class V water standard of the Surface Water Environmental Quality Standard GB3838-2002, it is considered heavy metal pollution;

[0105] Through the detailed water pollution type table, the pollution type can be accurately identified according to the specific water quality parameters. According to the determined pollution type, the corresponding purification plan can be selected, the purification plan can be executed, the polluted water quality can be treated, and the treated water quality information, i.e., the purified water quality information, can be obtained. This accurate identification helps to select the most appropriate purification plan, improve the purification efficiency and effect, standardize and automate the process of determining the pollution type, reduce the error and time of human judgment, and improve the speed and reliability of response. After identifying the specific pollution type, a targeted purification plan can be selected, avoiding unnecessary processing steps, saving resources and costs. The water pollution type table can be adjusted and updated according to different environments and needs, with high adaptability and flexibility. Based on the detailed pollution type table and specific water quality parameters, data-driven management and decision-making can be carried out, which improves the scientificity and effectiveness of water quality management, can quickly identify the pollution type and initiate the corresponding purification measures, ensure that the pollution is dealt with in a timely manner, prevent water quality deterioration and environmental pollution from spreading, and the automated identification and processing process improves the overall operating efficiency, making water quality monitoring and purification more efficient and reliable.

[0106] It is worth mentioning that after determining which type of pollution the water quality belongs to, choose the corresponding purification plan:

[0107] Water purification method: The height of the wetland matrix filling from top to bottom is 15cm sand layer (a 2:1 river sand and soil mixture), 20cm biological ceramsite layer and 20cm gravel layer, and canna and calamus are planted in the top soil layer;

[0108] In the hydraulic retention scheme, when the hydraulic retention time was 12-24h, the removal rate gradually increased and reached the highest level of 80.89%-94.05% at 24h;

[0109] Valve controls hydraulic retention time:

[0110] At mild levels, water enters the wetland and stays there for 12 hours;

[0111] At moderate levels, water entering the wetland stays there for 24 hours;

[0112] If the heavy metal level is low, the water will first go to the heavy metal pool to remove the heavy metals, and then go to the wetland to stay for 12 hours;

[0113] For moderate metal levels, the water first enters the heavy metal pool to remove heavy metals, and then enters the wetland for 24 hours;

[0114] Heavy metal pollution: the water enters the heavy metal pool to remove heavy metals, and then enters the wetland to stay for 24 hours;

[0115] At present, chemical methods are mostly used to treat heavy metal pollution in water, which can be subdivided into precipitation method, oxidation-reduction method, electrolysis method, etc.:

[0116] The precipitation method mainly uses special precipitation agents to increase the pH value of the water body, so that the heavy metals in the water are precipitated from the water in the form of hydroxide or carbonate.

[0117] The redox method mainly utilizes the redox reaction of metals to oxidize and reduce heavy metals in the water in ionic state into non-toxic or low-toxic substances, or convert them into valence ions that are not highly polluting to water bodies.

[0118] Using electrolysis to detect polluted water quality will cause the heavy metals in the water to gradually precipitate. This method can recover metals such as Cu, Ag, and Cd. According to statistics, there are currently more than 30 kinds of heavy metal ions that can be precipitated in this way.

[0119] The purified water quality information is returned as real-time water quality information to the step of judging whether the water quality meets the preset conditions according to the real-time water quality information; if the purified water quality information does not meet the preset conditions, the purified water quality information is judged to have water pollution and marked as residual polluted water quality information, including:

[0120] S301, obtaining a water quality pollution assessment threshold;

[0121] S302, obtaining corresponding purified water quality parameters according to the purified water quality information;

[0122] S303, returning the purified water quality parameter corresponding to the purified water quality information as the real-time water quality parameter corresponding to the real-time water quality information to the step of determining whether the real-time water quality parameter exceeds the water pollution assessment threshold;

[0123] If the purified water quality parameters do not exceed the water pollution assessment threshold, it is determined that there is no water pollution, and purification is stopped and the water is discharged;

[0124] If the purified water quality parameter exceeds the water pollution assessment threshold, it is determined that the purified water quality information has water pollution and is marked as residual polluted water quality information.

[0125] As in the above steps S301 to S303, the preset thresholds for evaluating water pollution are obtained again. These thresholds are consistent with those used before and are used to determine whether the water quality parameters are within a safe range. According to the purified water quality information, the corresponding purified water quality parameters are extracted. These parameters include water temperature, pH value, COD, TP, NH3-N and heavy metal content, etc., which reflect the water quality status after purification. The purified water quality parameters are used as real-time water quality information and input into the previous step of determining whether the water pollution assessment threshold is exceeded. The purified water quality parameters are compared with the water pollution assessment threshold again. If the purified water quality parameters do not exceed the assessment threshold, it is determined that the water quality has met the standard and there is no pollution. The purification is stopped and the water body is discharged. If the purified water quality parameters still exceed the assessment threshold, it is determined that the purified water quality is still polluted and marked as residual polluted water quality information. , it is necessary to continue purification treatment. By repeatedly checking the water quality parameters after purification, it is ensured that the water quality fully meets the preset standards before final discharge, and substandard water is prevented from entering the environment. A closed-loop feedback mechanism is established to allow the purification process to continue until the water quality fully meets the standards, thereby improving the reliability and effectiveness of water quality treatment. The purification strategy can be dynamically adjusted according to the specific parameters of the water quality after purification, and residual pollution can be treated more accurately to improve the purification effect. By judging whether the water quality after purification meets the standards, unnecessary purification operations can be avoided, resources and energy consumption can be saved, and overall operating efficiency can be improved. It is ensured that all discharged water bodies are strictly tested and purified to prevent pollutants from spreading into the environment, protect ecosystems and public health, and continuously test and feedback to continuously optimize the purification process to ensure that the treated water quality meets the highest standards and improve the overall purification effect.

[0126] The remaining polluted water quality information is returned as real-time water quality information to the table for obtaining water quality pollution types, and the water quality pollution type of the polluted water quality is obtained according to the polluted water quality information, and the purified water quality information is returned as real-time water quality information to the step of judging whether the water quality meets the preset conditions according to the real-time water quality information, until the step of judging that the water quality is not polluted, further comprising:

[0127] S401, obtaining residual polluted water quality information as real-time water quality information and returning it to the table for obtaining water quality pollution types, obtaining the water quality pollution type of the polluted water quality according to the polluted water quality information and returning the purified water quality information as real-time water quality information to the step of judging whether the water quality meets the preset conditions according to the real-time water quality information, and marking it as residual polluted water purification parameter;

[0128] S402, obtaining a standard multiple water purification assessment threshold;

[0129] S403, determining whether the residual polluted water purification parameter exceeds the standard multiple water purification assessment threshold;

[0130] If the residual polluted water purification parameters exceed the standard multiple water purification assessment threshold, the water purification scheme is judged to be abnormal and a warning message is issued;

[0131] If the residual contaminated water purification parameters do not exceed the standard multiple water purification assessment threshold, the water purification program is judged to be normal.

[0132] As in the above steps S401 to S403, the residual polluted water quality information is obtained, that is, the pollutant information still remaining in the water body after the last purification, and it is passed to the subsequent steps as real-time water quality information. A standard multiple water purification evaluation threshold is preset to evaluate the eligibility of the residual polluted water quality information in the multiple water purification process. The residual polluted water purification parameters are compared with the preset multiple water purification evaluation threshold. If the residual polluted water purification parameters exceed the threshold, it means that the pollutants remaining in the multiple water purification processes exceed the acceptable range. The water quality purification scheme is judged to be abnormal and a warning message is issued. If the residual polluted water purification parameters do not exceed the threshold, the water quality purification scheme is judged to be normal. Through the monitoring and evaluation of multiple water purification parameters, the purification scheme can be continuously optimized to ensure that each water purification process can achieve The expected effect improves purification efficiency and effect. When the residual contaminated water purification parameters exceed the set threshold, the abnormal situation of the purification plan can be discovered in time and a warning message can be issued so as to adjust the purification strategy in time to prevent the water quality pollution from continuing to deteriorate. By setting multiple water purification evaluation thresholds, abnormal situations can be monitored and identified during the purification process, which improves safety and stability and reduces the risk of accidents. By monitoring and evaluating the residual contaminated water purification parameters, real-time information of the water purification process can be provided, which enhances the transparency and controllability of the water purification process and enables managers to take necessary measures in time. By continuously monitoring and evaluating the residual contaminated water purification parameters, data-supported management decisions can be provided, enabling managers to adjust and optimize the purification plan more scientifically.
