Description

Technical Field

[0001] The present invention relates to the technical field of groundwater treatment, and in particular to a method and system for self-adjusting groundwater remediation operating parameters. Background Art

[0002] In the field of groundwater remediation, groundwater is difficult to detect and remediate in situ due to terrain. Therefore, groundwater is extracted from pumping wells and placed in a device for chemical reaction remediation. The remediation device includes a regulating tank, oxidation tank, neutralization tank, sedimentation tank, and clear water tank. A pH system is used in the oxidation tank to measure the pH value in the oxidation tank, compare it with the pH reference value, and add acid and base reagents as needed to adjust the groundwater to better react. This method can overcome the limitations of terrain, detect the pH value in the oxidation tank, and achieve better reaction results.

[0003] For example, Chinese invention patent publication number CN108773893A discloses a method and system for treating groundwater contamination with in-situ chemical oxidation based on zoning control, which falls within the field of groundwater remediation. The system comprises a reagent storage unit, a reagent injection unit, a pressurization unit, a monitoring unit, a metering and control unit, and an in-situ injection well. This system utilizes air pressure to inject an oxidizing agent into the groundwater through an injection well. It simultaneously monitors key indicators such as pH, redox potential, and conductivity during the in-situ oxidation reaction, automatically adjusting operating parameters such as injection volume and injection frequency based on changes in these monitored indicators.

[0004] For example, Chinese invention patent publication number CN111499044A discloses a method and equipment for treating groundwater contaminated by organic matter, relating to the technical field of contaminated groundwater remediation and treatment. The above-ground treatment method for contaminated groundwater includes the following steps: Step 1: Designing groundwater treatment parameters and processes through experiments based on the characteristics of the contaminants; Step 2: Controlling the residence time of the extracted contaminated groundwater in the water treatment equipment and the amount of liquid added to the dissolution tank through a PLC automatic control system; Step 3: Collecting and treating VOCs during the water treatment process; Step 4: Reinjecting the treated groundwater.

[0005] The aforementioned technology suffers from at least the following technical issues: The aforementioned application fails to achieve optimal reaction results during the chemical reaction process of groundwater remediation, or during groundwater extraction. In the oxidation tank, it is impossible to establish an adaptive reaction control closed loop based on real-time pH data, making it difficult to achieve precise, time-varying optimization of oxidation reaction parameters. Summary of the Invention

[0006] In view of the deficiencies in the prior art, the present invention provides a method and system for self-adjusting groundwater remediation operating parameters, which can effectively solve the problems involved in the above-mentioned background technology.

[0007] To achieve the above objectives, the present invention is implemented through the following technical solutions: The first aspect of the present invention provides a method for self-adjusting groundwater remediation operation parameters, including: step one, extracting groundwater into the remediation device in batches, monitoring the state of the groundwater in the remediation device, and collecting and analyzing the state parameters of the groundwater, thereby initializing the remediation operation parameters of the remediation device; step two, repairing the groundwater through the remediation device, monitoring the remediation state of the groundwater, thereby obtaining and analyzing the remediation state parameters of the groundwater, and determining whether to self-adjust the remediation operation parameters of the remediation device to which the groundwater belongs; step three, after the groundwater remediation is completed, determining whether to optimize the extraction parameters of the remediation device by analyzing the remediation process parameters of the groundwater.

[0008] Compared with the prior art, the embodiments of the present invention have at least the following advantages or beneficial effects:

[0009] (1) The present invention provides a method and system for self-adjusting operating parameters for groundwater remediation. This method significantly improves remediation efficiency and accuracy through phased and dynamic parameter management. State parameters are collected and analyzed during the initialization phase, and operating parameters are monitored and self-adjusted in real time during the remediation process, enabling flexible responses to water quality changes. After remediation is complete, parameters are extracted based on process parameter optimization, derived from the systematic design and dynamic adjustment strategy of the overall remediation process. This reduces resource waste, shortens remediation time, improves groundwater purification quality, and ensures the long-term benefits and sustainability of the remediation project.

[0010] (2) Initializing the remediation operation parameters by extracting groundwater in batches and monitoring and analyzing its state parameters has the advantage of being able to quickly grasp the initial characteristics of groundwater. Groundwater composition is complex and varies from region to region. By collecting and analyzing state parameters, parameters such as the treatment intensity and dosage of the remediation device can be accurately set. This avoids the problems of low remediation efficiency or excessive resource consumption caused by improper parameter settings in the early stages of remediation, effectively improving the initial adaptability and pertinence of the remediation work, and ensuring that the remediation process is carried out efficiently and orderly.

[0011] (3) During the remediation process, the remediation status is monitored in real time and the operating parameters are automatically adjusted. The advantage lies in the ability to dynamically respond to changes in water quality during the remediation process. By continuously acquiring and analyzing remediation status parameters, such as residual pollutant concentration and reaction product content, remediation deviations can be detected in a timely manner. Once it is determined that the current parameters are no longer suitable, the remediation device operating parameters are automatically adjusted to ensure that the remediation process is always in the best state, thereby improving the remediation quality and efficiency. This beneficial effect is due to the precise grasp of the dynamic nature of the remediation process and timely intervention.

[0012] (4) After groundwater remediation is completed, the remediation process parameters are analyzed to optimize the extraction parameters. This has the advantage of enabling dynamic iterative upgrades of the remediation system. The remediation process parameters include multi-dimensional information such as the amount of water extracted, the extraction time, and the pollutant concentration change curve. By analyzing the correlation between these multi-dimensional remediation process parameters, the quantitative evaluation role of the extraction link in the entire groundwater remediation cycle can be accurately located.

[0019] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0020] Reference Figure 1As shown, the first aspect of the present invention provides a method for self-adjusting groundwater remediation operation parameters, including: step one, extracting groundwater into the remediation device in batches, monitoring the state of the groundwater in the remediation device, and collecting and analyzing the state parameters of the groundwater, thereby initializing the remediation operation parameters of the remediation device; step two, remediating groundwater through the remediation device, monitoring the remediation state of the groundwater, thereby obtaining and analyzing the remediation state parameters of the groundwater, thereby determining whether to self-adjust the remediation operation parameters of the remediation device to which the groundwater belongs; step three, after the groundwater remediation is completed, determining whether to optimize the extraction parameters of the remediation device by analyzing the remediation process parameters of the groundwater.

[0021] Specifically, the state parameters of groundwater are collected and analyzed. The specific analysis process is as follows: the state parameters of groundwater include the ion concentration of each detected ion in groundwater, the ionic strength of groundwater and the osmotic pressure of groundwater.

[0022] Utilizing professional water quality testing equipment such as ion chromatographs and atomic absorption spectrometers, we quantitatively analyze the various ions detected in groundwater samples and directly determine their concentrations. Groundwater testing includes conventional ion indicators such as hydrogen, hydroxide, and sulfate ions, and can also expand detection to other characteristic ions based on pollution characteristics. Secondly, the molar concentration of each detected ion is multiplied by the square of its corresponding charge to obtain a set of numerical values. These values ​​are then added and summed, and the sum is multiplied by one-half to calculate the groundwater's ionic strength. An osmometer is used to directly measure the osmotic pressure of groundwater samples, completing comprehensive monitoring of the three parameters.

[0023] Figure 3 This is a schematic diagram of the groundwater extraction monitoring and parameter initialization process of the present invention, which describes a schematic diagram of the initialization process of groundwater remediation. Before the remediation device is started, groundwater is first introduced into the system by batch extraction, and the groundwater status in the device is monitored in real time. The status parameters are synchronously collected and data analysis is performed, and the initial values ​​of the remediation operation parameters are set accordingly.

[0024] Metric ratio values ​​are extracted from the database to quantify the degree of influence of the relative ratio between the ion concentration and the predetermined defined ion concentration in the database, the relative ratio between the ion strength and the predetermined defined ion strength in the database, and the relative ratio between the osmotic pressure and the predetermined defined osmotic pressure in the database on the abnormal state index of groundwater. The various influence degrees are summarized to obtain the abnormal state index of groundwater.

[0025] The groundwater abnormal state index is used to digitally indicate the groundwater abnormal state index, and the specific expression is:

[0026] ;

[0027] P is the abnormal state index of groundwater, H is the number of each detection ion, H=1, 2, 3, ..., Y, Y is the total number of each detection ion, C H is the ion concentration of the Hth detection ion in groundwater, JC H is the defining ion concentration of the Hth detection ion preset in the database, D is the ionic strength of the groundwater, JD is the defining ionic strength preset in the database, Q is the osmotic pressure of the groundwater, JQ is the defining osmotic pressure preset in the database, W1 is the measurement ratio value corresponding to the ionic concentration preset in the database, W2 is the measurement ratio value corresponding to the ionic strength preset in the database, and W3 is the measurement ratio value corresponding to the osmotic pressure preset in the database.

[0028] The definition of ion concentration is used to characterize the upper limit set for ion concentration; the definition of ionic strength is used to characterize the upper limit set for ionic strength; the definition of osmotic pressure is used to characterize the upper limit set for osmotic pressure.

[0029] In the groundwater system, the ion concentration of each detected ion is a basic parameter. The level of ion concentration will directly affect the ionic strength of the groundwater, because ionic strength is essentially a measure of the sum of the product of the ion concentration and the square of the ion charge in the solution. Therefore, when the concentration of the detected ion increases (or decreases), the total effective concentration contribution of the ions in the solution increases (or decreases), which in turn leads to an increase (or decrease) in ionic strength. The ionic strength is closely related to the osmotic pressure of the groundwater. The increase in ionic strength will enhance the interaction between ions in the solution, and the effects such as the binding of ions to water molecules will change the properties of the solution system. According to the principle of osmotic pressure, an increase in ionic strength will cause the osmotic pressure of the groundwater to increase (conversely, a decrease in ionic strength will reduce the osmotic pressure). These three parameters work together to determine the abnormal state index of groundwater. An abnormal increase or decrease in the detected ion concentration will disrupt the original equilibrium between ionic strength and osmotic pressure. The deviation of ionic strength from the normal range will further affect the stability of osmotic pressure. The imbalance in the physical and chemical properties of groundwater caused by the coordinated changes in multiple parameters will eventually lead to an increase in the abnormal state index of groundwater, reflecting that the groundwater may be in abnormal conditions such as pollution and changes in the hydrochemical environment. On the contrary, if each parameter is maintained within the normal fluctuation range, the abnormal state index of groundwater will be at a lower level, and the groundwater is in a relatively stable and normal state.

[0030] The measurement ratio value corresponding to the ion concentration indicates the degree of influence of the relative ratio between the ion concentration and the defining ion concentration on the abnormal state index of groundwater; the measurement ratio value corresponding to the ion strength indicates the degree of influence of the relative ratio between the ion strength and the defining ion strength on the abnormal state index of groundwater; the measurement ratio value corresponding to the osmotic pressure indicates the degree of influence of the relative ratio between the osmotic pressure and the defining osmotic pressure on the abnormal state index of groundwater.

[0031] The database stores several mapping relationships, such as parameter-metric ratio mappings. These mappings are bound to groundwater monitoring data and experimental metadata through structured tables (such as parameter mapping tables and weight configuration tables) or associative query statements, forming a complete groundwater abnormality assessment system. Therefore, the metric ratio values ​​corresponding to ion concentration, ionic strength, and osmotic pressure can be directly queried from the database. The metric ratio values ​​for ion concentration, ionic strength, and osmotic pressure all range from 0 to 1.

[0032] Furthermore, the repair operation parameters of the repair device are initialized. The specific initialization process is: the abnormal state index of groundwater and the historical abnormal state indexes stored in the database are subjected to absolute difference processing in turn, and the processing results are sorted in ascending order, and the historical abnormal state index corresponding to the processing result ranked first is extracted and marked as the target abnormal state index. This historical abnormal state index is calculated based on the ion concentration, ion strength and osmotic pressure of all detected ions (H=1,2,3,...,Y), where the detected ions include various mineral ions (such as 、 、 、 etc.), not limited to or ions; therefore, when the mineral concentration is too high, the index will also increase and be identified as an abnormal state, and the reagent injection rate and groundwater residence time corresponding to the target abnormal state index will be obtained.

[0033] The abnormal state index of groundwater is differentiated from the target abnormal state index, and the processing result is marked as the abnormal state deviation value of groundwater.

[0034] Differentiated treatment refers to subtracting the target abnormal state index from the abnormal state index of groundwater.

[0035] The pH value of the groundwater is obtained and compared with the defined pH value stored in the database. At the same time, the abnormal state index of the groundwater is compared with the target abnormal state index.

[0036] At the beginning of the reaction, there is a fixed residence time of the added acidic (alkaline) reagent and groundwater.

[0037] If the pH value is greater than the defined pH value and the abnormal state index of the groundwater is greater than or equal to the target abnormal state index, the acid reagent injection rate and the groundwater residence time are increased based on the abnormal state deviation value of the groundwater.

[0038] If the pH value is greater than the defined pH value and the abnormal state index of the groundwater is less than the target abnormal state index, the acid reagent injection rate and the groundwater residence time are reduced based on the abnormal state deviation value of the groundwater.

[0039] If the pH value is lower than the defined pH value and the abnormal state index of the groundwater is greater than or equal to the target abnormal state index, the alkaline reagent injection rate and the groundwater residence time are increased based on the abnormal state deviation value of the groundwater.

[0040] If the pH value is lower than the defined pH value and the abnormal state index of the groundwater is lower than the target abnormal state index, the alkaline reagent injection rate and the groundwater residence time are reduced based on the abnormal state deviation value of the groundwater.

[0041] Initialize the repair operation parameters of the repair device based on the reagent injection rate and groundwater residence time.

[0042] The historical abnormality indices stored in the database refer to a series of abnormality index data recorded for groundwater remediation scenarios at different time periods or under different operating conditions. This historical data, obtained through corresponding monitoring and calculation processes during past groundwater remediation processes, reflects the degree and characteristics of groundwater anomalies at the time and serves as a basis for comparison when initializing current remediation operating parameters.

[0043] The defined pH value is a critical pH value pre-determined in the database based on groundwater remediation goals, water quality safety standards, and the suitability of remediation processes. The pH value in groundwater only appears above or below the defined value due to material exchange and chemical reactions with rocks and soil during its migration through geological strata. Contact with rock formations rich in alkaline minerals will increase the pH value due to increased hydroxide ion concentration. Sulfide deposits, for example, will cause sulfide oxidation to increase hydrogen ion concentration and lower the pH value. Furthermore, human activities such as industrial wastewater discharge and agricultural fertilizer use introduce acidic and alkaline substances, further exacerbating pH deviations from the defined value.

[0044] Based on the abnormal state deviation value of groundwater, the acid reagent injection rate and groundwater residence time are reduced. When the pH value is less than the threshold value, a segmented mapping relationship is established in the database between the abnormal state deviation value and the alkaline reagent injection rate increment coefficient. That is, the abnormal state deviation values ​​in different intervals correspond to the alkaline reagent injection rate increment coefficient. The alkaline reagent injection rate increment coefficient is multiplied by the current alkaline reagent injection rate to obtain the reagent injection rate increase. Finally, the calculated injection rate increase is added to the current reagent injection rate to obtain the precisely adjusted alkaline reagent injection rate. The injection equipment is regulated accordingly to achieve refined control of the injection acceleration rate. At the same time, a segmented mapping relationship is established between the abnormal state deviation value and the groundwater residence time extension coefficient. That is, the abnormal state deviation values ​​in different intervals correspond to the groundwater residence time extension coefficient. The groundwater residence time extension coefficient is multiplied by the current groundwater residence time to obtain the groundwater residence time increase. Finally, the calculated groundwater residence time increase is added to the current groundwater residence time to obtain the precisely adjusted groundwater residence time, thereby improving remediation efficiency. Similarly, when the pH value is greater than the defined value, follow the above logic and adjust the acidic reagent to an alkaline reagent accordingly.

[0045] The alkaline reagent injection rate increment coefficient is determined according to the abnormal state deviation value range of groundwater in the groundwater treatment scenario, and is used to calculate the proportional coefficient of the increase in the acid and alkaline reagent injection rate.

[0046] The groundwater residence time extension coefficient is a proportional coefficient determined within the groundwater abnormal state deviation value range and used to calculate the increase in groundwater residence time.

[0047] Step 2: Repair groundwater through the repair device, monitor the repair status of the groundwater, thereby obtaining and analyzing the repair status parameters of the groundwater, and determining whether to self-adjust the repair operation parameters of the repair device to which the groundwater belongs.

[0048] Specifically, the groundwater restoration status parameters are analyzed, and the specific analysis process is: the groundwater restoration status parameters include the reduction of the groundwater abnormal state index, the turbidity of the groundwater in the monitoring sub-period, and the by-product concentration of the groundwater in the monitoring sub-period.

[0049] Figure 4 This is a schematic diagram of the groundwater remediation monitoring and parameter self-adjustment process of the present invention, which shows the dynamic adjustment mechanism during the remediation process; after the remediation operation parameters are initialized, the groundwater remediation device is started and the remediation status is monitored; by analyzing the remediation status parameters obtained in real time, it is determined whether self-adjustment is required: if necessary, the operation parameters are updated and the remediation is continued; if not, it is determined whether the remediation is completed; if not, the remediation is continued; if completed, the process ends.

[0050] For the reduction of the abnormal state index of groundwater, the abnormal state index of groundwater at the beginning of the monitoring sub-period is subtracted from the abnormal state index of groundwater at the end of the monitoring sub-period, and the result is the reduction of the abnormal state index of groundwater; for groundwater turbidity monitoring, a portable turbidity meter can be used to take samples and measure on-site at different monitoring points; for groundwater by-product concentration monitoring, after collecting water samples, high-performance liquid chromatography, gas chromatography-mass spectrometry and other instruments are used to conduct qualitative and quantitative analysis of disinfection by-products, organic by-products, etc. to obtain accurate concentration data.

[0051] The measurement ratio values ​​are extracted from the database to quantify the influence of the relative ratio between turbidity and the defined turbidity, the relative ratio between by-product concentration and the defined by-product concentration, and the reduction of the abnormal state index of groundwater on the remediation efficiency index of groundwater during the monitoring sub-period. The influence degrees are summarized to obtain the remediation efficiency index of groundwater during the monitoring sub-period.

[0052] The groundwater restoration efficiency index within the monitoring sub-period is used to digitally indicate the groundwater restoration effect. The specific expression is:

[0053] ;

[0054] XF is the restoration efficiency index of groundwater in the monitoring sub-period, P is the reduction of the abnormal state index of groundwater, ZD is the turbidity of groundwater in the monitoring sub-period, JZD is the defined turbidity preset in the database, FC is the byproduct concentration of groundwater in the monitoring sub-period, JFC is the defined byproduct concentration preset in the database, A1 is the measurement ratio value of the reduction of the abnormal state index preset in the database, A2 is the measurement ratio value of the turbidity preset in the database, and A3 is the measurement ratio value of the byproduct concentration preset in the database.

[0055] In the groundwater remediation efficiency evaluation system, turbidity is defined to characterize the upper limit value set for turbidity; by-product concentration is defined to characterize the upper limit value set for by-product concentration.

[0056] In the groundwater remediation efficiency evaluation system, the reduction in the abnormal state index, turbidity, and by-product concentration are interrelated and synergistically affect the remediation effect. The reduction in the abnormal state index, as the core evaluation indicator, directly reflects the degree of pollutant removal and water quality improvement, while turbidity and by-product concentration indirectly change the abnormal state index by affecting the progress of the remediation reaction. Specifically, when the turbidity increases, suspended particles adsorb the remediation agent, weakening the effective contact between the agent and the pollutants, hindering the efficiency of pollutant degradation, and resulting in a limited reduction in the abnormal state index; excessive by-product concentration will inhibit microbial activity or produce secondary pollution, interfering with the normal progress of the remediation reaction, and also resulting in insufficient reduction in the abnormal state index. The three form a dynamic correlation mechanism, and any abnormal parameter may disrupt the balance and reduce the overall remediation efficiency.

[0057] The reduction in the abnormal state index of groundwater is the difference between the abnormal state index before and after groundwater remediation within the monitoring sub-period. It comprehensively reflects the extent to which the abnormal state has been reduced due to improvements in parameters such as ion concentration, ionic strength, and osmotic pressure, and reflects the effectiveness of remediation in reducing the abnormal state. The measurement ratio of turbidity is used to quantify the relative ratio between turbidity and defined turbidity, reflecting the degree of influence of turbidity parameters on the remediation efficiency index of groundwater within the monitoring sub-period. The measurement ratio of by-product concentration is used to quantify the relative ratio between by-product concentration and defined by-product concentration, reflecting the degree of influence of by-product concentration parameters on the remediation efficiency index of groundwater within the monitoring sub-period. The measurement ratio of the reduction in the abnormal state index is used to quantify the degree of influence of the reduction in the abnormal coefficient on the remediation efficiency index of groundwater within the monitoring sub-period.

[0058] The mapping relationships between these parameters are stored in a database and, through structured tables (such as remediation parameter mapping tables and weight configuration tables) or associative query statements, are bound to water quality data (including abnormal conditions, turbidity, byproduct concentrations, etc.) and remediation process metadata (such as remediation methods and reagent dosages) during the groundwater monitoring period, thereby constructing a complete groundwater remediation effectiveness evaluation system. Based on this system, the measured ratio values ​​of the reduction in the abnormal condition index, the measured ratio values ​​of turbidity, and the measured ratio values ​​of byproduct concentration can be directly queried from the database. These ratio values ​​are combined with the corresponding weighted ratios and calculated to ultimately summarize the remediation effectiveness index. The reasonable range of each measured ratio value must be determined based on the remediation objectives and water quality standards through extensive experimental verification and in-depth data analysis to ensure the scientific rationality of the evaluation logic and achieve a digital and accurate representation of the groundwater remediation effect.

[0059] Furthermore, it is determined whether to self-adjust the repair operation parameters of the groundwater repair device. The specific determination process is: comparing the groundwater repair efficiency index in the monitoring sub-period with the repair efficiency threshold stored in the database.

[0060] If the restoration efficiency index of groundwater in the monitoring sub-period is less than the restoration efficiency threshold, it is determined that the restoration operation parameters of the restoration device to which the groundwater belongs are to be self-adjusted.

[0061] If the restoration efficiency index of groundwater in the monitoring sub-period is greater than or equal to the restoration efficiency threshold, it is determined that the restoration operation parameters of the restoration device belonging to the groundwater are not self-adjusted.

[0062] The repair efficiency threshold is used to represent the lower limit value set by the repair efficiency index.

[0063] If the remediation efficiency index of groundwater in the monitoring sub-period is less than the remediation efficiency threshold, it means that the groundwater remediation effect is not good and the release rate of the regulating agent needs to be adjusted.

[0064] Comparing the groundwater remediation efficiency index within a monitoring sub-period with the remediation efficiency threshold and automatically adjusting the remediation device operating parameters based on this index has significant practical advantages. This dynamic control mechanism, through quantitative assessment of remediation effectiveness, can promptly identify inefficiencies in the remediation process and accurately determine the optimization direction for key parameters such as the reagent delivery rate, thereby avoiding resource waste and extended remediation cycles caused by lagging or unreasonable parameters.

[0065] Furthermore, the restoration operation parameters of the groundwater restoration device are self-adjusted. The specific adjustment process is: obtaining the average temperature of the restoration process corresponding to the target abnormal state index and marking it as the reference temperature.

[0066] In the initial stage of the reaction, there is a fixed stirring speed.

[0067] When the pH value is greater than the defined pH value:

[0068] The average temperature of groundwater in the monitoring sub-period is obtained and compared with the reference temperature. If the average temperature of groundwater in the monitoring sub-period is greater than or equal to the reference temperature, the acid reagent addition rate of the remediation device in the next monitoring sub-period is increased based on the remediation efficiency threshold, and the stirring speed is increased at the same time to make the reaction more complete.

[0069] When increasing the delivery speed based on the repair efficiency threshold, the repair efficiency threshold in the database has a corresponding acid reagent delivery speed increment coefficient. The acid reagent delivery speed increment coefficient is obtained according to the repair efficiency threshold, and then the acid reagent delivery speed increment coefficient is multiplied by the current acid reagent delivery speed to obtain the increase in the acid reagent delivery speed that needs to be increased in the next sub-period. The acid reagent delivery speed increment is added to the current acid reagent delivery speed to obtain the precisely adjusted acid reagent delivery speed.

[0070] When increasing the stirring speed based on the repair efficiency threshold, the repair efficiency threshold in the database has a corresponding stirring speed increment coefficient. The stirring speed increment coefficient is obtained according to the repair efficiency threshold, and then the stirring speed increment coefficient is multiplied by the current stirring speed to obtain the stirring speed increase that needs to be increased in the next sub-period. The stirring speed increase is added to the current stirring speed to obtain the precisely adjusted stirring speed.

[0071] The acid (alkaline) reagent injection rate increment coefficient is determined based on the repair efficiency threshold and is used to calculate the proportional coefficient of the increase in the acid (alkaline) reagent injection rate. The acid (alkaline) reagent injection rate increment coefficient is stored in the database and forms a one-to-one correspondence with the repair efficiency threshold.

[0072] If the average temperature of groundwater in the monitoring sub-period is lower than the reference temperature, the acid reagent addition rate of the repair device in the next monitoring sub-period is increased based on the remediation efficiency index of groundwater in the monitoring sub-period, while the stirring speed remains unchanged.

[0073] When the injection speed is increased based on the remediation efficiency index of groundwater in the monitoring sub-period, the remediation efficiency index in the database has a corresponding acid reagent injection speed increment coefficient. The acid reagent injection speed increment coefficient is obtained according to the remediation efficiency index, and then the acid reagent injection speed increment coefficient is multiplied by the current acid reagent injection speed to obtain the increase in the acid reagent injection speed that needs to be increased in the next sub-period. The increase in the acid reagent injection speed is added to the current acid reagent injection speed to obtain the precisely adjusted acid reagent injection speed.

[0074] When the stirring speed is increased based on the remediation efficiency index of groundwater in the monitoring sub-period, the remediation efficiency index in the database has a corresponding stirring speed increment coefficient. The stirring speed increment coefficient is obtained according to the remediation efficiency index, and then the stirring speed increment coefficient is multiplied by the current stirring speed to obtain the increase in the stirring speed that needs to be increased in the next sub-period. The stirring speed increase is added to the current stirring speed to obtain the precisely adjusted stirring speed.

[0075] When the pH value is lower than the defined pH value:

[0076] If the average temperature of groundwater in the monitoring sub-period is greater than or equal to the reference temperature, the alkaline reagent addition rate of the remediation device in the next monitoring sub-period is increased based on the remediation efficiency threshold, and the stirring speed is increased at the same time to make the reaction more complete.

[0077] When the delivery speed is increased based on the repair efficiency threshold, the adjustment process of increasing the delivery speed of the acidic reagent of the repair device in the next monitoring sub-period based on the repair efficiency threshold is followed, and the acidic reagent is adjusted to the alkaline reagent accordingly.

[0078] If the average temperature of groundwater in the monitoring sub-period is lower than the reference temperature, the alkaline reagent addition rate of the remediation device in the next monitoring sub-period is increased based on the remediation efficiency index of groundwater in the monitoring sub-period, while keeping the stirring speed unchanged.

[0079] Based on the restoration efficiency index of groundwater in the monitoring sub-cycle, the adjustment process of increasing the acid reagent delivery speed of the restoration device in the next monitoring sub-cycle based on the restoration efficiency index of groundwater in the monitoring sub-cycle is followed, and the acid reagent is adjusted to an alkaline reagent accordingly.

[0080] After the adjustment is completed, the remediation efficiency index of groundwater in the adjustment monitoring sub-period is obtained, and it is determined whether to make a secondary self-adjustment to the remediation operation parameters of the remediation device to which the groundwater belongs. At the same time, the reagent injection speed is obtained and compared with the reagent injection speed reference interval stored in the database. If the reagent injection speed does not fall within the reagent injection speed reference interval, it means that the groundwater pH value is difficult to restore to the normal range, affecting the overall remediation goal. In this case, an early warning will be issued for the reagent injection speed, and an audible and visual alarm will be set at the control center of the remediation device and key locations around it. When the injection speed exceeds the reference interval, the alarm will immediately emit a flashing light and a harsh sound to attract the attention of the staff so that they can quickly detect the abnormality. If the reagent injection speed falls within the reagent injection speed reference interval, no early warning will be issued for the reagent injection speed.

[0081] A monitoring sub-cycle is a fixed-duration, continuous monitoring period that divides the entire groundwater remediation process. It serves as the basic time unit for data collection, remediation effect evaluation, and parameter adjustment.

[0082] The reference temperature is the average temperature of the repair process corresponding to the target abnormal state index and is an important temperature benchmark in the entire parameter adjustment process.

[0083] The target abnormal state index reflects the degree of deviation from normal operating conditions during the groundwater remediation process.

[0084] The groundwater remediation efficiency index within the monitoring sub-period is a quantitative reflection of the actual working effect of the remediation device within the period, reflecting the progress and quality of groundwater remediation.

[0085] The average temperature of the remediation process corresponding to the target abnormal state index is used as the reference temperature, providing a benchmark for subsequent adjustments. This reference temperature integrates the temperature parameters of ideal remediation conditions in historical data and represents the optimal temperature conditions for the remediation reaction. Combined with the pre-defined pH value, the groundwater environment is divided into acidic and alkaline scenarios, forming a "temperature-pH value" dual-dimensional reference system. This multi-indicator linkage setting can more accurately match the remediation needs under different environmental conditions, avoiding the limitations of single indicator adjustment.

[0086] Furthermore, it is determined whether to perform secondary self-adjustment on the repair operation parameters of the groundwater repair device. The specific determination process is: comparing the repair efficiency index of the groundwater in the adjustment detection sub-cycle with the repair efficiency threshold.

[0087] If the restoration efficiency index of groundwater in the adjustment monitoring sub-period is greater than or equal to the restoration efficiency threshold, it is determined that no secondary adjustment is made to the restoration operation parameters of the restoration device belonging to the groundwater.

[0088] If the remediation efficiency index of groundwater in the adjustment monitoring sub-period is less than the remediation efficiency threshold, it is determined to perform secondary self-adjustment on the remediation operation parameters of the remediation device to which the groundwater belongs. The specific process of the secondary self-adjustment is as follows: when the pH value is greater than the defined pH value, the average temperature of the groundwater in the adjustment monitoring sub-period is obtained. If the average temperature of the groundwater in the adjustment monitoring sub-period is greater than or equal to the reference temperature, the acid reagent addition speed of the remediation device in the next monitoring sub-period is increased based on the remediation efficiency threshold, and the stirring speed is increased at the same time to make the reaction more complete, and a technical coordination instruction is generated at the same time.

[0089] The average temperature of groundwater in the adjusted monitoring sub-period is collected by using a temperature sensor during the time interval of the adjusted monitoring sub-period. All temperature data collected in the sub-period are collected and the average value is calculated by the arithmetic mean method.

[0090] If the average temperature of groundwater during the adjustment monitoring sub-period is lower than the reference temperature, the acid reagent addition rate of the repair device in the next monitoring sub-period is increased based on the repair efficiency index of groundwater during the adjustment monitoring sub-period while keeping the stirring speed unchanged, and a technical coordination instruction is generated, and a repair warning is issued at the same time.

[0091] When the pH value is lower than the defined pH value: obtain the average temperature of the groundwater during the adjustment monitoring sub-period; if the average temperature of the groundwater during the adjustment monitoring sub-period is greater than or equal to the reference temperature, increase the alkaline reagent addition rate of the repair device in the next monitoring sub-period based on the repair efficiency threshold, and increase the stirring speed at the same time to make the reaction more complete and generate technical coordination instructions.

[0092] When the alkaline reagent delivery speed is increased based on the repair efficiency threshold, the repair efficiency threshold in the database has a corresponding alkaline reagent delivery speed increment coefficient. The alkaline reagent delivery speed increment coefficient is obtained according to the repair efficiency threshold, and then the alkaline reagent delivery speed increment coefficient is multiplied by the current delivery speed to obtain the increase in the alkaline reagent delivery speed that needs to be increased in the next sub-period. The alkaline reagent delivery speed increase is added to the current alkaline reagent delivery speed to obtain the precisely adjusted alkaline reagent delivery speed.

[0093] If the average temperature of groundwater during the adjustment monitoring sub-period is lower than the reference temperature, the alkaline reagent addition rate of the repair device in the next monitoring sub-period is increased based on the repair efficiency index of groundwater during the adjustment monitoring sub-period, while keeping the stirring speed unchanged, and generating technical coordination instructions, and issuing repair warnings at the same time.

[0094] When based on the remediation efficiency index of groundwater in the monitoring sub-period, the remediation efficiency index in the database has a corresponding alkaline reagent delivery rate increment coefficient. The alkaline reagent delivery rate increment coefficient is obtained according to the remediation efficiency index, and then the alkaline reagent delivery rate increment coefficient is multiplied by the current delivery rate to obtain the increase in the alkaline reagent delivery rate that needs to be increased in the next sub-period. The alkaline reagent delivery rate increase is added to the current alkaline reagent delivery rate to obtain the precisely adjusted alkaline reagent delivery rate.

[0095] The technical coordination instructions include adding bioaugmentation, physical adsorption, or chemical synergistic technologies. Bioaugmentation can be achieved through the addition of microorganisms, where microorganisms with strong degrading capabilities for target pollutants are added to groundwater. The microorganisms use the pollutants as a carbon source and energy source for growth and metabolism, accelerating the decomposition of pollutants. Physical adsorption involves installing fixed-bed adsorption columns or moving-bed adsorption equipment in a groundwater extraction-treatment-recharge system. After groundwater is extracted and flows through the adsorption device, pollutants are intercepted and removed by the adsorbent. The purified water is then recharged into the ground, achieving a recycling treatment of contaminated groundwater. Chemical synergistic technology targets difficult-to-degrade organic matter or heavy metal pollutants by adding chemical oxidants or reducing agents.

[0096] After the adjustment is completed, the groundwater restoration efficiency index during the secondary adjustment monitoring sub-period is obtained and compared with the restoration efficiency threshold. If the groundwater restoration efficiency index during the secondary adjustment monitoring sub-period is still less than the restoration efficiency threshold, a restoration warning is issued, and sound and light alarms are set at the control center of the restoration device and key locations around it. When the injection speed exceeds the reference range, the alarm immediately emits flashing lights and harsh sounds to attract the attention of staff and enable them to quickly detect abnormalities.

[0097] The definition of the secondary monitoring sub-cycle is consistent with that of the monitoring sub-cycle.

[0098] If the restoration efficiency index of groundwater in the secondary adjustment monitoring sub-period is greater than or equal to the restoration efficiency threshold, the restoration status of groundwater will be continuously monitored.

[0099] Step 3: After the groundwater remediation is completed, the groundwater remediation process parameters are analyzed to determine whether the extraction parameters of the remediation device should be optimized.

[0100] Determine whether to optimize the extraction parameters of the remediation device. The specific determination process is as follows: the extraction parameters include the extraction volume, the remediation efficiency index of groundwater in each monitoring sub-period is obtained, and the average processing is performed. The processing result is marked as the average value of the remediation efficiency index of groundwater in the monitoring period, and compared with the average remediation efficiency limit value stored in the database.

[0101] The average remediation efficiency limit value is the core benchmark value used for decision-making and parameter optimization in the groundwater remediation operation parameter self-adjustment method. It refers to the average critical indicator of remediation efficiency stored in the database based on statistical laws and project goals.

[0102] If the mean value of the restoration efficiency index of groundwater during the monitoring period is greater than the average restoration efficiency limit value stored in the database, it is determined that the extraction parameters of the restoration device should be optimized to increase the next extraction volume.

[0103] If the average value of the remediation efficiency index of groundwater during the monitoring period is less than or equal to the average remediation efficiency limit value stored in the database, it is determined not to optimize the extraction parameters of the remediation device, and at the same time, the extraction volume of the remediation device is reduced based on the average value of the remediation efficiency index of groundwater during the monitoring period.

[0104] Based on the restoration efficiency index of groundwater during the monitoring period, the deviation between the mean value of the restoration efficiency index and the average restoration efficiency limit value is first calculated. In the database, different gradients are divided according to the range of the deviation degree. Each gradient corresponds to a reduction in the extraction volume. The existing extraction volume is subtracted from the reduction in extraction volume to obtain the reduced extraction volume of the restoration device and the next extraction volume.

[0105] In terms of the data collection and processing logic mentioned above, during the groundwater remediation process, the entire monitoring period is divided into multiple sub-periods, and the remediation efficiency within each sub-period is quantified separately to form a remediation efficiency index. Through the arithmetic mean method, the indices of each sub-period are added and divided by the number of sub-periods to obtain the mean remediation efficiency index within the monitoring period. This processing method, on the one hand, can carefully capture the effect changes at different stages of the remediation process and avoid the impact of single data deviation on the overall evaluation; on the other hand, through mean calculation, the discrete sub-period data are integrated into representative indicators, objectively reflecting the actual operating effect of the remediation device throughout the monitoring period, and providing a reliable basis for subsequent parameter adjustments.

[0106] In the parameter adjustment decision-making mechanism described above, the calculated mean restoration effectiveness index is compared with a pre-set average restoration effectiveness threshold in the database. This threshold is a reference benchmark determined by integrating extensive historical restoration data, industry standards, and the project's expected restoration goals. This comparison establishes a logical chain of "data-standard-decision": using data as the basis and standards as a reference, the final decision on whether to adjust the extraction parameters is made.

[0107] Furthermore, when the mean value of the repair efficiency index is greater than the threshold, it means that the repair efficiency exceeds expectations under the current repair device extraction parameter settings. In this case, the extraction volume is increased. If the mean value of the repair efficiency index is less than or equal to the threshold, it indicates that the current parameter settings are not achieving the ideal repair effect. In this case, instead of optimizing the parameters, the extraction volume is directly reduced. This not only reduces energy consumption caused by ineffective extraction, but also prompts the system to reassess its operating status. While maintaining the current repair conditions, it gradually explores more optimal extraction parameter combinations, driving the repair process towards higher efficiency.

[0108] The mean value of the groundwater remediation efficiency index during the monitoring period is the value obtained by calculating the mean of the groundwater remediation efficiency index in each monitoring sub-period (for example, arithmetic mean, adding the indices of each sub-period and dividing by the number of sub-periods). It reflects the average level of groundwater remediation efficiency during the monitoring period and is used to measure the strength of the remediation effect produced by the actual operation of the remediation device in this period.

[0109] The average remediation efficiency threshold stored in the database is a pre-set standard value that serves as the basis for determining whether remediation device extraction parameters need optimization. This threshold, determined based on extensive historical groundwater remediation case studies and experimental data, represents a reasonable and effective remediation performance threshold. This threshold is then compared with the average remediation efficiency index over the actual monitoring period to determine whether the current remediation operation is meeting the target.

[0110] Furthermore, the extraction parameters of the repair device are optimized. The specific optimization process is: the mean value of the repair efficiency index of groundwater during the monitoring period is differentiated from the average repair efficiency limit value, and the processing result is marked as the repair margin.

[0111] Figure 5 This is a schematic diagram of the repair process and extraction parameter optimization process of the present invention, which describes the system optimization phase after the repair is completed. After the groundwater repair is completed, the system enters the post-repair evaluation phase: first, a comprehensive analysis of various parameters recorded during the repair process is performed; based on the analysis results, it is determined whether the extraction parameters of the repair device need to be optimized. If optimization is determined to be necessary, the extraction parameter adjustment operation is performed; if optimization is determined not to be necessary, the current extraction parameter settings are maintained; and finally, the entire post-repair evaluation process is completed.

[0112] The repair margin is compared with the defined repair margin stored in the database. If the repair margin is greater than or equal to the defined repair margin, the extraction volume of the repair device is obtained for comparison.

[0113] If the extraction volume of the repair device is not equal to the defined extraction volume, the extraction volume of the repair device is increased and optimized based on the repair margin.

[0114] The extraction volume is defined as the maximum volume of the extraction device.

[0115] The extraction volume of the repair device is increased and optimized based on the repair margin. First, different gradients are divided according to the numerical value of the repair margin. Each gradient corresponds to a corresponding extraction volume increment. The extraction volume increment is added to the current volume to obtain the next extraction volume.

[0116] If the extraction volume of the repair device is equal to the bounded extraction volume, no optimization is performed to increase the extraction volume of the repair device.

[0117] If the repair margin is smaller than the defined repair margin, the extraction volume of the repair device is not increased and optimized.

[0118] Restoration margin is the mean value of the groundwater restoration efficiency index during the monitoring period minus the average restoration efficiency threshold value.

[0119] Defining the repair margin is a standard value pre-set in the database. It serves as the basis for judging the repair margin situation (whether it has reached the level where the extraction volume needs to be increased). It is used to compare with the actual calculated repair margin to determine the optimization operation of the extraction volume of the repair device.

[0120] The calculation of the remediation margin is fundamental to the entire adjustment process. By performing a differential calculation (e.g., taking the difference between the mean remediation efficiency index over the groundwater monitoring period and the average remediation efficiency threshold) we can translate the abstract notion of remediation effectiveness into a concrete numerical value. This numerical value directly reflects the degree of deviation between the actual remediation efficiency and the standard: a larger positive value indicates that the remediation effect exceeded expectations, while a negative value or zero indicates that it fell short of expectations. As an intermediate indicator, the remediation margin provides a quantifiable basis for subsequent parameter adjustments, freeing optimization decisions from the constraints of subjective experience and basing them on objective data.

[0121] The adjustment process achieves precise decision-making through a "double-layer screening" mechanism. First, the repair margin is compared with the defined repair margin: when the repair margin is greater than or equal to the defined repair margin, it indicates that there is significant redundancy in the current repair effect, and the system enters the second-layer screening, that is, comparing the actual extraction volume with the defined extraction volume. If the two are not equal, it means that the current extraction parameters have not reached the optimal configuration. At this time, based on the specific value of the repair margin, the extraction volume is increased proportionally, which can not only make full use of the redundancy of the repair performance to improve the processing efficiency, but also avoid over-extraction; if the actual extraction volume is equal to the defined value, it proves that the current parameters are already optimal and no adjustment is required, preventing increased energy consumption and equipment loss due to blind operation. When the repair margin is less than the defined repair margin, it means that the actual repair effect is only slightly above the standard or does not meet the standard. At this time, the existing extraction volume is maintained unchanged to avoid disrupting the current repair balance due to rash increases in extraction volume and prevent increased environmental risks.

[0122] This adjustment method offers multiple advantages. In terms of resource management, it accurately identifies and optimizes space through the repair margin, adjusting the extraction volume only when necessary, reducing ineffective energy consumption and equipment wear, thereby lowering repair costs. In terms of risk prevention and control, it defines the repair margin as a safety threshold to avoid secondary environmental problems such as groundwater level drop and soil structure damage caused by excessive extraction. In terms of system adaptability, this strategy can dynamically adjust extraction parameters based on complex environmental factors such as different geological conditions and pollutant concentrations, ensuring that the repair device maintains efficient and stable operation, balancing repair efficiency and environmental safety.
