Description

Technical Field

[0001] The present invention relates to the technical field of groundwater pollution, and in particular to a groundwater well intelligent linkage rapid pollution control system. Background Art

[0002] LNAPL (light non-aqueous phase liquids) contamination of groundwater in petroleum and petrochemical enterprises is widespread. Due to its high concentration, LNAPL is easily adsorbed in soil, forming a source of continuous release. Once contaminated, it easily migrates with water into aquifers, affecting a wide range of areas. The resulting oil blooms can also easily cause adverse social impacts. Therefore, controlling and remediating LNAPL contamination is crucial.

[0003] Currently, the detection of LNAPL contamination in groundwater at petroleum and petrochemical companies primarily relies on regular groundwater sampling and testing, where the presence of LNAPL is determined based on contamination concentrations, or by using beehive pipes to pump groundwater up and determine the presence of NAPL phases based on contamination on the inner wall of the pipe. This method is relatively slow in detecting LNAPL, relying on sporadic testing. It is unable to provide effective early warning when contamination occurs, nor can it implement remediation measures. Currently, some companies' groundwater-related facilities primarily consist of groundwater monitoring wells. Remediation measures such as in-situ reaction walls and chemical oxidant injection require comprehensive remediation plans and require extensive groundwork. For operating companies, these measures pose high safety risks and remediation costs. Furthermore, remediation plans often require extensive expert review and, once established, are difficult to adjust, resulting in a lengthy period of time and insufficient time for timely LNAPL treatment. Therefore, establishing a comprehensive system for LNAPL monitoring and remediation is crucial.

[0035] The present invention provides an intelligent, linked, rapid pollution control system for groundwater wells. Compared to existing technologies, it offers the following advantages: Existing technologies for LNAPL monitoring primarily rely on regular water quality testing or, when significant water quality anomalies are detected, use beleived pipe inspections. Existing patent documents also focus on proposing complete remediation plans after pollution is discovered. These plans are often deterministic and cannot be effectively adjusted based on changes in pollution. Pollution remediation also relies on a single remediation technology, and the entire process often requires groundbreaking work and expert review before implementation. This can easily delay treatment and cause contamination migration. The present invention achieves a high degree of automation in monitoring and remediation. By modifying existing monitoring wells, it can rapidly respond to LNAPL contamination, make remediation adjustments based on pollution changes, and conduct simple assessments. This effectively reduces health and environmental risks before implementing a major remediation plan, thus being of great significance.

[0036] Other features and advantages of the present invention will be described in the following description, and in part will become apparent from the description, or will be understood by practicing the present invention. The purposes and other advantages of the present invention can be realized and obtained by the structures particularly pointed out in the description, claims and drawings.

[0043] To make the objectives, technical solutions and advantages of the present invention more clear, embodiments of the present invention are described in further detail below with reference to the accompanying drawings.

[0044] Petroleum and petrochemical sites pose a significant risk of groundwater contamination. Previous pollution surveys have shown that LNAPL contamination is common in groundwater, and sensitive receptors are numerous around industrial sites. Failure to effectively control LNAPL contamination can easily lead to severe environmental and social impacts. For operating companies, large-scale remediation projects pose significant safety risks, require extensive expert review before implementation, are time-consuming, and can easily lead to the rapid migration of contamination.

[0045] Currently, existing technologies have integrated monitoring and remediation devices, but most of them are designed as complete remediation solutions. Often, the entire device cannot be changed after being placed in a certain location, and there are relatively few monitoring and remediation systems for LNAPL. For example, existing technology CN112570434A proposes a soil and groundwater remediation method for in-situ remediation, which pre-determines the scope of the soil and groundwater to be remediated, the current status of the pollution, and the remediation target; determines the technical parameters of the in-situ injection well remediation system based on the scope of the soil and groundwater to be remediated, including the number of injection wells, the agent impact radius, the injection well diameter, the injection pressure, and the agent dosage ratio; then, constructs the in-situ injection wells based on the parameters; creates groundwater monitoring wells; and injects an alkali-activated sodium persulfate solution into the constructed in-situ injection wells, allowing the agent to diffuse to the entire contaminated area under the migration of groundwater. Through the migration of groundwater, the agent reacts with organic matter in the soil and groundwater, degrading the pollutants in the contaminated area. However, this prior art primarily describes a parameter calculation method for in-situ injection of a chemical and the establishment of downstream groundwater monitoring wells. This represents a complete remediation solution, does not involve automated monitoring, and offers a single solution tailored to a single contamination scenario. It lacks internal facility changes and cannot create a flexible experimental plan tailored to changes in the contaminated area. Furthermore, this prior art's remediation method is solely in-situ injection, with no adjustments to the remediation method based on the location of the pollution plume, and no adjustments to the injection and monitoring wells.

[0046] The prior art CN113843267A establishes a groundwater remediation system based on a groundwater well group. The groundwater remediation system includes a groundwater monitoring well group, a groundwater pumping well group, a groundwater remediation well group, a water quality analysis center, and a data processing center. The monitoring wells in the groundwater monitoring well group are connected to the main pumping pipe through a pumping branch pipe. A comprehensive water quality monitoring probe is arranged in the monitoring well, and an atmospheric pressure monitoring probe is arranged on the ground outside the monitoring well. The water quality analysis center receives the water quality monitoring signal from the comprehensive water quality monitoring probe, analyzes the water quality monitoring signal, and sends the analysis result to the data processing center. The data processing center performs in-depth processing on the water quality monitoring signal and outputs the result to the groundwater pumping well group and the groundwater remediation well group. However, this prior art also belongs to a complete remediation solution. During the implementation of the remediation solution, it only involves changes in process parameters, not changes in the remediation solution. The monitoring items are also mainly used for the assessment of pollution effects rather than the discovery and early warning of pollution, which cannot solve the problem of delayed pollution response. The three types of water wells in this prior art cannot be converted into each other, and the monitoring content is also the common five parameters and other indicators, which cannot achieve rapid monitoring and early warning of pollution.

[0047] Prior art CN114417474A provides a PRB remediation system with monitoring capabilities. The PRB remediation system includes a seepage reaction wall module, a groundwater monitoring module, and a control terminal. The seepage reaction module includes a first water barrier, a second water barrier, and a reaction wall assembly. The first and second water barriers are located on either side of the reaction wall assembly, and the ends of the reaction wall assembly are detachably connected to the first and second water barriers. The groundwater monitoring module is located near the seepage reaction module and is used to obtain water quality information near the seepage reaction module. The groundwater monitoring module is in communication with the control terminal and transmits the water quality information to the control terminal. The control terminal analyzes the environmental risk situation near the groundwater monitoring module based on the obtained water quality information near the seepage reaction module. However, the monitoring purpose of this prior art is still to evaluate the remediation results, rather than to quickly detect pollution. Therefore, it cannot achieve rapid response and treatment of pollution. Moreover, this prior art still cannot realize rapid changes in pollution. Once the remediation facilities are installed, they cannot be adjusted. The groundbreaking work is heavy and the safety risks are also great.

[0048] Prior art CN111633016B provides an integrated device and method for monitoring and repairing urban groundwater, comprising a device base, a first support plate fixedly mounted on the top of the device base, a second support plate fixedly mounted on one side of the first support plate, a rotating shaft rotatably connected to one side of the first support plate, a wire drum fixedly connected to the outer wall of the rotating shaft, a suspension rope wound around the outer wall of the wire drum, one end of the rotating shaft passing through the second support plate and fixedly connected to a crank, a sleeve plate sleeved on the outer wall of the rotating shaft provided between the crank and the second support plate. However, this prior art is primarily targeted at the field of urban groundwater, and primarily focuses on pollution detection and response for heavy metal pollution. Although similar to the technical fields involved in this application, the objects to be detected by the two are completely different.

[0049] In summary, while many existing technologies address the remediation of organically contaminated groundwater, relatively few address the rapid monitoring and remediation of LNAPL. Most are complete remediation solutions that lack flexible and automatic adjustments. Once fixed, the facilities cannot be changed, and the remediation facilities are relatively simple. To address the aforementioned shortcomings of the existing technologies, the present invention strives to combine existing conditions and proposes a system that can rapidly monitor LNAPL contamination and automatically take action. This system dynamically adjusts to changes in the current contamination status, reduces labor costs, and enables rapid response to contamination, mitigating the risk of environmental incidents caused by prolonged contamination leakage and migration.

[0050] Figure 1 A schematic diagram of a grouped intelligent, linked, rapid pollution control system for groundwater wells, according to one embodiment of the present invention, is shown. This system integrates monitoring and remediation, enabling automated, rapid pollution detection and response without requiring extensive manual effort. Its flexibility and adaptability significantly reduce the time needed for decision-making in large-scale remediation projects, effectively controlling current pollution. This is crucial for oil and petrochemical companies in controlling pollution and minimizing its impact on the environment and human health.

[0051] A groundwater well intelligent linkage rapid pollution control system includes a groundwater well system and a master control system. The groundwater well system includes multiple intelligent linkage wells located in a target area. When an intelligent linkage well detects a target pollutant, it generates a pollution occurrence signal and marks the current intelligent linkage well as a polluted well. The master control system determines a response area based on the pollution occurrence signal and the location of the polluted well. It divides the intelligent linkage wells within the response area into a preparation group, a treatment group, and a monitoring group. It then transmits instructions for drug delivery, pollution remediation, and pollution monitoring to the preparation group, treatment group, and monitoring group, respectively.

[0052] In one embodiment, Figure 2As shown, the intelligent linkage well includes: a monitoring outer well and a repair inner well, wherein an LNAPL monitoring and early warning device is installed on the side wall of the monitoring outer well, which is used to continuously monitor the target pollutants in the groundwater and generate a pollution occurrence signal after the target pollutants are detected, wherein the target pollutant is a light non-aqueous phase liquid (LNAPL). Specifically, the LNAPL monitoring and early warning device uses ultraviolet fluorescence to continuously monitor the target pollutants in the groundwater, which is resistant to interference and not prone to contamination. Furthermore, in order to save resources, except when pollution occurs, only the LNAPL monitoring and early warning device in the entire management and control system is always working, and other devices only start working after pollution occurs and are in standby mode on a daily basis.

[0053] In one embodiment, Figure 2 As shown, a biopharmaceutical dosing device is provided at the bottom of the side wall of the monitoring outer well, which is used to inject biopharmaceuticals into the groundwater in the monitoring outer well through a spraying device according to the agent injection instruction, wherein the biopharmaceutical is a preparation that promotes biodegradation. Specifically, the preparatory group upstream of the pollution receives the agent injection instruction and injects a biopharmaceutical that can promote biodegradation into the groundwater in the monitoring outer well through the biopharmaceutical dosing device. The biopharmaceutical slowly increases the biodegradation rate as the groundwater flows downstream. Furthermore, the biopharmaceutical dosing device is composed of a biopharmaceutical and a spraying device. Among them, the biopharmaceutical includes slow-release oxygen materials, indigenous bacteria, etc.

[0054] In one embodiment, Figure 2 As shown, a pollution detection device is installed on the sidewall of the monitoring well. It is used to regularly test the groundwater according to pollution monitoring instructions and transmit the regular test results to the overall control system. Specifically, the monitoring team downstream of the pollution receives the pollution monitoring instructions and performs regular groundwater testing using the pollution detection device. The test data is automatically uploaded to the database module of the overall control system. Furthermore, to conserve resources, the pollution detection device only activates testing when pollution occurs and after receiving the pollution monitoring instruction.

[0055] In one embodiment, Figure 2 As shown, an extraction pump is installed on the sidewall of the outer monitoring well. This pump is used to extract groundwater from the outer monitoring well in response to pollution remediation instructions. The extracted groundwater is then injected into the inner remediation well via the pollution detection device, where target pollutants in the groundwater are treated. Specifically, the treatment group where the pollution is located receives the pollution remediation instructions and uses the extraction pump to extract groundwater from the outer monitoring well so that the target pollutants in the groundwater can be treated in the inner remediation well.

[0056] In one embodiment, Figure 2As shown, the inner wall of the remediation inner well is composed of two rows of rotatable remediation layers. One remediation layer is a gravity primary separation layer, and the other remediation layer is an adsorption layer. The gravity primary separation layer is composed of multiple L-shaped baffles arranged in sequence along the inner wall, and the adsorption layer is composed of multiple downward-inclined baffles arranged in sequence along the inner wall. The downward-inclined baffles are composed of an upper layer of adsorption sponge and a lower layer of support plates. The L-shaped baffles are spaced apart from the downward-inclined baffles. Specifically, the inner wall is composed of two rows of rotatable remediation layers. One side is the adsorption layer, which is composed of an upper layer of specific adsorption sponge and a lower layer of support plates. After adsorption saturation, the adsorption sponge can be renewed to ensure the continuous effectiveness of the device. The other side is the gravity primary separation layer, which is L-shaped. Groundwater entering the remediation inner well first enters the gravity primary separation layer. The low-density substances in the LNAPL can slowly accumulate there. After initial separation, the upper NAPL phase liquid overflows into the adsorption layer, achieving effective pollution removal. The remaining groundwater enters the next layer, and the cycle repeats. Finally, the pollution is effectively adsorbed and the remaining groundwater returns to the remediation outer well.

[0057] In one embodiment, Figure 2 As shown, a baffle control device is provided on the outer wall of the inner repair well, which is used to start the repair layer according to the pollution remediation instruction. After the repair layer is started, it rotates to a specific point. After the groundwater extracted by the extraction pump enters the inner repair well, it is first separated by gravity through the initial gravity separation layer to obtain an upper NAPL phase liquid and a lower residual liquid. The upper NAPL phase liquid enters the adsorption layer, and the pollutants in the upper NAPL phase liquid are adsorbed by the adsorption layer. The lower residual liquid returns to the outer repair well to be injected into the inner repair well again through the extraction pump to achieve pollution circulation treatment. Specifically, the repair layer is controlled by the baffle control device suspended on the outer wall of the inner repair well. Under normal conditions, the repair layer is placed vertically downward along the side wall and no repair treatment is performed. When pollution occurs, the overall control system divides the intelligent linkage wells. The intelligent linkage wells divided into treatment groups start the repair layer through the baffle control device. The repair layer rotates to a specific point and begins to function.

[0058] In one embodiment, the overall control system includes a database module for storing the locations of groundwater wells in the target area, the plant layout, and the hydrogeological conditions of the target area. Specifically, the database module stores data including, but not limited to, basic plant information such as the plant layout, real-time groundwater monitoring data, and the hydrogeological conditions of the plant area. Ports are also available for manually adding well locations. Real-time data is stored for a two-year period. When an abnormal value is detected, the abnormal time is recorded and stored in a focused partition.

[0059] In one embodiment, the overall control system includes: a groundwater well grouping response module, which is used to determine the response area, The intelligent linkage wells in the well are divided into preparation group, treatment group and monitoring group. The group length D of each group along the water flow direction is determined based on the permeability coefficient, hydraulic gradient and control time. The pollution well is taken as the center O and divided into two groups on both sides. The group length D is used as the interval. The intelligent linkage wells in the area are used as a preparation group, and the area where the polluted wells are located The intelligent linkage wells in the well are used as treatment groups to pollute the downstream area of ​​the well. The intelligent linkage wells in the monitoring group are used as monitoring groups. Specifically, Figure 1 As shown, when an outlier is detected during routine automated inspection of a smart linkage well within a target area, the groundwater well grouping response module groups the smart linkage wells within the response area, centered around the contaminated well. Furthermore, the group length D along the water flow direction is calculated. The length of each group along the water flow direction is calculated using the formula D = K × I × T, where K represents the permeability coefficient; I represents the hydraulic gradient; and T represents the control time. In one embodiment, the enterprise determines the likely time of contamination based on experience and previous production and maintenance records, and assigns a value to T based on the acceptable contamination treatment time.

[0060] In one embodiment, the overall control system includes: a rapid assessment module, which, based on the pollution status data fed back by the intelligent linkage wells, delineates all areas that exceed the groundwater risk control value, thereby determining the health risk of personnel in the target area, and performs trend analysis based on the historical real-time monitoring results of pollutants, determines the time to reach the sensitive receptor closest to the groundwater flow direction, and issues early warnings for subsequent pollution levels based on the length of time. Specifically, the rapid assessment module analyzes human health risks based on the pollution status data, and focuses on the inhalation risk level, delineates all areas that exceed the groundwater risk control value, thereby determining the health risk to factory employees. And based on the real-time monitoring results of pollutants in previous periods, a trend analysis is performed through no less than 8 periods of detection data, determines the time to reach the sensitive receptor closest to the groundwater flow direction, and issues early warnings for subsequent pollution levels based on the length of time.

[0061] In the present invention, the locations of groundwater wells, plant layout, and hydrogeological conditions are entered into a database module in advance, and real-time groundwater monitoring data is collected. After data processing and analysis, the intelligent linkage wells are grouped according to the location of the target pollutants through the groundwater well grouping response module, and corresponding response instructions are given. The pollution status is evaluated in real time through the rapid assessment module to achieve rapid grasp of the pollution situation.

[0062] In one embodiment, Figure 2As shown, the management and control system also includes a display system, which includes: a display module and an early warning module. Among them, the display module is used to display the latest detected contaminated wells, the grouping of surrounding groundwater wells, the distribution of human health risks, the detection data of each period, and the risk early warning results. The early warning module is used to send the pollution occurrence signal and the risk early warning results to the preset smart mobile device. Specifically, the display system has the dual functions of display and early warning. It can display the location of the latest LNAPL-contaminated groundwater wells, the grouping of surrounding groundwater wells, the distribution of human health risks on the site, the detection data of each period, and the risk early warning results. When pollution occurs, an alarm will be issued in time, and a signal will be sent to the preset management personnel's mobile phone.

[0063] like Figure 1 As shown, the present invention groups the pollution detection wells on both sides with the group length D as the interval, and divides the intelligent linkage wells into a preparation group, a treatment group, and a monitoring group. The preparation group upstream of the pollution mainly uses preparations that can promote biodegradation, including slow-release oxygen materials, indigenous flora, etc. The treatment group where the pollution is located mainly performs rapid gravity initial separation and adsorption on the target pollutants. The monitoring group downstream of the pollution mainly conducts long-term monitoring of risks by increasing the monitoring frequency.

[0064] In one embodiment, when an increase in the number of intelligent linkage wells in the target area is detected, the intelligent linkage wells are automatically updated and the corresponding modules are automatically started, and the grouping and evaluation and warning are all changed in real time.

[0065] The main features of this invention are its integrated monitoring and remediation capabilities. Its simple construction and high degree of automation allow it to be retrofitted into existing monitoring wells. A remediation well is added to the existing monitoring well, and an extraction pump is placed on the sidewall of the existing monitoring well. Water pumped out by the extraction pump passes through a contamination detection device and enters the remediation well. A biopharmaceutical dosing device is placed at the lowest level of the existing monitoring well's sidewall, and injection is performed using a spray device when needed. LNAPL monitoring and early warning equipment is suspended on the sidewall of the existing monitoring well, transmitting signals back to the overall control system upon detection of contamination.

[0066] Lightweight non-dissolved phase (LNAPL) is widespread in the groundwater of petroleum and petrochemical enterprises, but detection is often delayed, and once discovered, rapid action is difficult. This invention proposes an organic matter remediation system based on a pollution plume (or plume), comprising a master control system, a display system, and a groundwater well system. By retrofitting and linking existing groundwater monitoring wells throughout the plant (target area), the master control system automatically analyzes and categorizes LNAPL contamination in any well (the refitted intelligent linked well) based on real-time monitoring. Different well types respond differently, enabling rapid detection and treatment of contamination. The zoning process is automatically repeated and the corresponding modules activated as the contamination level changes. Wells in different locations are efficiently utilized for different remediation measures, and dynamic adjustments can be made. No complex manual processing is required. The refitted intelligent linked wells are equipped with an extraction pump, a biopharmaceutical dosing device, and an adsorption layer remediation inner well, fully utilizing existing monitoring wells and saving costs. The present invention can facilitate daily environmental management of petroleum and petrochemical enterprises, reduce the possibility of pollution out of the factory boundary, and reduce the occurrence of environmental incidents.

[0067] Figure 3 A flowchart of the steps of a method for intelligent linkage and rapid pollution control of groundwater wells according to an embodiment of the present invention is shown.

[0068] like Figure 3 As shown, in step S301, a groundwater well system comprising multiple intelligently linked wells located in a target area generates a pollution signal when a target pollutant is detected by an intelligently linked well, marking the current intelligently linked well as a contaminated well. Specifically, based on the enterprise's own pollution control requirements, a groundwater well system is established downstream of a contaminated site within a petroleum and petrochemical enterprise. Alternatively, existing groundwater monitoring wells are renovated and retrofitted, with groundwater extraction pumps, biopharmaceutical dosing devices, LNAPL monitoring and early warning equipment, and pollution detection devices installed within the renovated wells. This creates a ready-to-use intelligently linked well. The location, depth, and other information of the enterprise's intelligently linked wells are stored in the master control system. Daily, real-time LNAPL monitoring is performed solely through the LNAPL monitoring and early warning equipment, while other devices remain in standby mode. When the LNAPL monitoring and early warning equipment in a specific intelligently linked well detects an anomaly, it immediately reports the location of the current intelligently linked well. The master control system automatically categorizes the surrounding wells into a preparatory group, a treatment group, and a monitoring group based on a pre-set calculation method. Wells in different groups receive different responses, enabling rapid pollution control.

[0069] like Figure 3As shown, in step S302, the overall control system determines the response area based on the pollution occurrence signal and the location information of the contaminated wells, divides the intelligent linkage wells within the response area into a preparation group, a treatment group, and a monitoring group, and transmits agent delivery instructions, pollution remediation instructions, and pollution monitoring instructions to the preparation group, treatment group, and monitoring group, respectively. Specifically, the overall control system quickly predicts pollution based on the detection results trend of the treatment process, guides the parameters of the remediation measures, and, combined with the results of a simple human health risk assessment, delineates the area to be covered within the site, guiding the company to quickly address human health risks. When an increase in the number of groundwater wells containing LNAPL phases is detected, the groundwater well grouping is automatically updated and the corresponding module is automatically activated. The grouping and assessment and warning changes are all real-time. The entire process is highly automated, effectively remediating pollution and giving the company time to remediate the pollution. If a large-scale remediation project is required, the plan can be determined through expert discussion.

[0070] This invention transforms and connects existing groundwater wells in target areas. Based on real-time NAPL phase detection results, the transformed intelligently linked wells are automatically classified and individually responded to the current pollution status, achieving pollution zoning control. Basic human health assessments are performed based on concentration distributions. Combined with groundwater risk control values, areas of volatile toxicity are defined, guiding businesses in their coverage efforts. Pollution predictions are then made based on concentration changes, with the final results displayed in real time on a display system. This invention utilizes intelligent means to capture and rapidly respond to subtle, high-concentration LNAPL phase contamination in groundwater. The fully automated process eliminates the need for complex human monitoring and effectively improves the efficiency of handling leak accidents.

[0071] Figure 4 A flowchart of the steps of a method for intelligent linkage and rapid pollution control of groundwater wells according to another embodiment of the present invention is shown.

[0072] like Figure 4 As shown, in step S401, the target pollutants in the groundwater are monitored in real time through the intelligent linkage wells in the target area. Specifically, according to the pollution control requirements of petroleum and petrochemical enterprise A, the existing groundwater monitoring wells downstream of the tank area of ​​enterprise A are repaired and renovated, and groundwater extraction pumps, biological agent injection devices, LNAPL monitoring and early warning equipment, and pollution detection devices are installed. Then, they are placed in the repaired wells to form intelligent linkage wells in a ready state. The location, depth and other information of the intelligent linkage wells within the enterprise, the plant layout, hydrogeological conditions, groundwater levels, etc. are all stored in the overall control system. On a daily basis, only the LNAPL monitoring and early warning equipment is used to carry out real-time monitoring of LNAPL. Other devices are in standby mode. The monitoring data is stored for a period of 2 years, and abnormal values ​​are permanently stored separately.

[0073] like Figure 4As shown, in step S402, when the intelligent linkage well detects the target pollutant, a contamination signal is generated and the current intelligent linkage well is marked as contaminated. Specifically, one day, the LNAPL monitoring and early warning equipment in the W3 intelligent linkage well detects an anomaly and immediately feeds W3's location information back to the overall control system.

[0074] like Figure 4 As shown, in step S403, the intelligent linkage wells within the response area are divided into a preparatory group, a treatment group, and a monitoring group, centered on the contaminated well and separated by group lengths. Specifically, the overall control system uses a preset calculation method: the nearby equipment was overhauled just six months ago and no contamination was found. Therefore, according to the formula D = K × I × T, the grouping interval is calculated to be 15 meters. The wells surrounding W3 are automatically classified into a preparatory group (W1, W2), a treatment group (W3, W4), and a monitoring group (W5, W6).

[0075] like Figure 4 As shown, in step S404, the reagent injection instruction, pollution remediation instruction and pollution monitoring instruction are transmitted to the preparation group, treatment group and monitoring group respectively. Specifically, the intelligent linkage wells in different groups perform different types of responses and start rapid pollution treatment.

[0076] like Figure 4 As shown, in step S405, the preparation group injects a biopharmaceutical into the groundwater through the injection device according to the agent injection instruction, wherein the biopharmaceutical is a preparation that promotes biodegradation. Specifically, W1 and W2 start the biopharmaceutical injection device and use the internal injection device to inject the slow-release oxygen material.

[0077] like Figure 4 As shown, in step S406, the processing group, in accordance with the contamination remediation instructions, extracts groundwater from the monitoring outer well. The extracted groundwater is then injected into the remediation inner well via the contamination detection device, where the target contaminants in the groundwater are treated. Specifically, W3 and W4 activate the groundwater extraction pumps, extracting the groundwater and then injecting it back into the remediation inner well. The remediation layer of the remediation inner well rotates and is fixed in a position where one layer is higher and the other side is lower. The LNAPL-containing groundwater flows through the initial gravity separation layer for simple gravity separation. The LNAPL overflowing from the upper layer then flows into the adsorption layer for rapid adsorption. The remaining groundwater returns to the original well for recycling.

[0078] like Figure 4 As shown, in step S407, the monitoring team performs regular groundwater testing according to the pollution monitoring instructions and transmits the regular test results to the overall control system. Specifically, W5 and W6 activate the groundwater pollution detection device, perform water extraction testing every three days, and feed the results back to the overall control system.

[0079] The display system further shows the location of the most recently detected LNAPL-contaminated well, the grouping of surrounding groundwater wells, the distribution of human health risks within the site, and the test data for each period. The master control system rapidly predicts contamination based on the test results trends from the past ten treatment periods. The system finds that contamination concentrations are gradually decreasing, no new LNAPL has appeared, and human health risks are within controllable limits. Therefore, there is no need to adjust existing well groupings. Once the test concentration is within the acceptable range, the system stops responding and returns to a standby state, ready for the next response.

[0080] The purpose of this invention is to establish a rapid response system for LNAPL contamination of groundwater, a common occurrence in petroleum and petrochemical enterprises. Based on existing monitoring wells, repair devices such as inner well repair and inner wall hanging extraction are placed. When LNAPL is detected, the overall control system receives the signal and begins automatic analysis and calculation. It then categorizes the intelligent linkage wells within the plant (target area) into preparatory, treatment, and monitoring groups, and issues instructions. Different groups of intelligent linkage wells respond differently, rapidly addressing the contamination. Simultaneously, the overall control system conducts a quick and simple risk analysis of the contamination to guide the enterprise's basic emergency response measures. The entire process is highly automated, reducing the risk of contamination leaving the plant due to untimely detection, and eliminating the need for complex human monitoring and processing.

[0081] In one embodiment, based on the pollution control requirements of petroleum and petrochemical enterprise B, the existing groundwater monitoring wells downstream of enterprise B's sewage treatment pool were repaired and renovated, and groundwater extraction pumps, biopharmaceutical dosing devices, LNAPL monitoring and early warning equipment, and pollution detection devices were installed. Then, they were placed in the repaired wells to form a ready-to-use intelligent linkage well. Due to the lack of groundwater wells, new wells were built. The location, depth and other information of the enterprise's internal intelligent linkage wells, plant layout, hydrogeological conditions, groundwater levels, etc. are all stored in the master control system. On a daily basis, only real-time LNAPL monitoring is carried out through the LNAPL monitoring and early warning equipment, and other devices are in standby mode. The monitoring data is stored for a period of 2 years, and abnormal values ​​are permanently stored separately. One day, the LNAPL monitoring and early warning equipment at the W5 intelligent linkage well detected an anomaly and immediately fed back W5's location information to the overall control system. The system used a preset calculation method: a nearby device had just been overhauled a month prior and no contamination had been detected. Therefore, using the formula D = K × I × T, the system automatically classified the wells surrounding W5 into a preparatory group (W1, W3), a treatment group (W5), and a monitoring group (W2, W6). Different groups of intelligently linked wells respond differently, initiating rapid contamination treatment. W1 and W3 activate the biopharmaceutical dosing device, injecting microbial agents using an internal injection device. W5 activates the groundwater extraction pump, extracting groundwater and reinjecting it into the remediation well. The remediation layer in the remediation well rotates, fixed at a high-side, low-side position. LNAPL-laden groundwater flows through the primary gravity separation layer for simple gravity separation. LNAPL overflowing from the upper layer flows into the adsorption layer, where it is rapidly adsorbed. The remaining groundwater returns to the original well for recycling. W2 and W6 activate the groundwater contamination detection device, conducting water extraction tests every two days and feeding the results back to the overall control system. The display system shows the location of the most recently detected LNAPL-contaminated wells, the grouping of surrounding groundwater wells, the distribution of human health risks within the site, and each period's testing data. The master control system conducted a rapid pollution forecast based on the test results trends from the past ten treatment phases. It discovered no significant decrease in contamination concentrations, and new LNAPL had appeared in W2. Consequently, the existing situation was regrouped: the preparation group remained unchanged, treatment groups W2 and W5, and monitoring groups W6 and W7. The corresponding response facilities were also adjusted. Assessments confirmed that the human health risks were within controllable limits. Therefore, no adjustments to the existing well groupings were necessary. Once the test concentrations were within the acceptable range, the response was discontinued and the system returned to standby mode, ready for the next response.

[0082] In one embodiment, based on the pollution control requirements of petroleum and petrochemical company C, the existing groundwater monitoring wells downstream of the wastewater treatment pool of company C were repaired and renovated. A groundwater extraction pump, a biopharmaceutical dosing device, LNAPL monitoring and early warning equipment, and pollution detection equipment were installed. These were then placed inside the repaired well to form a ready-to-use intelligent linkage well. Due to the limited number of groundwater wells, new wells were constructed. The location, depth, and other information of the company's internal intelligent linkage wells, plant layout, hydrogeological conditions, and groundwater levels are all stored in the master control system. Daily real-time LNAPL monitoring is only carried out using the LNAPL monitoring and early warning equipment, while other devices are in standby mode. Monitoring data is stored for a two-year period, and abnormal values ​​are permanently stored. One day, the LNAPL monitoring and early warning equipment at the W5 intelligent linkage well detected an anomaly and immediately fed back W5's location information to the overall control system. The system used a preset calculation method: a nearby unit had just been overhauled 24 months prior and no contamination had been detected. Therefore, according to the formula D = K × I × T, the grouping interval was 15 meters. However, considering the company's acceptable range and the plant boundary 12 meters downstream, the grouping interval was calculated to be 12 meters. The system then automatically classified the wells surrounding W5 into a preparation group (W1, W3), a treatment group (W5), and a monitoring group (W2, W6). Different groups of intelligently linked wells respond differently, initiating rapid contamination treatment. W1 and W3 activate the biopharmaceutical dosing device, injecting microbial agents using an internal injection device. W5 activates the groundwater extraction pump, extracting groundwater and reinjecting it into the remediation well. The remediation layer in the remediation well rotates, fixed at a high-side, low-side position. LNAPL-containing groundwater flows through the primary gravity separation layer for simple gravity separation. LNAPL overflowing from the upper layer flows into the adsorption layer, where it is rapidly adsorbed. The remaining groundwater returns to the original well for recycling. W2 and W6 activate the groundwater contamination detection device, conducting water extraction tests every five days and feeding the results back to the overall control system. The display system shows the location of the most recently detected LNAPL-contaminated wells, the grouping of surrounding groundwater wells, the distribution of human health risks within the site, and each period of testing data. The total control system made a rapid pollution prediction based on the trend of the test results of the last 12 treatment processes and found that the pollution concentration had not decreased significantly and new LNAPL appeared in W2. Therefore, the existing situation was regrouped, that is, the preparation group remained unchanged, the treatment groups were W2 and W5, the monitoring groups were changed to W6 and W7, and the corresponding response facilities were changed. After evaluation, it was changed to 5m around W2. 2 The system indicates the location of the health risk and prompts for coating. If, after long-term monitoring, the contamination is not effectively removed, the system prompts other remediation options, and the company contacts professional remediation companies and experts to design the remediation project.

For example, in some jurisdictions, according to legislation and patent practices, computer-readable storage media do not include electrical carrier signals and telecommunications signals.

[0086] In summary, the present invention provides an intelligent linkage rapid pollution control system for groundwater wells. Compared with the existing technology, it has the following advantages: the existing technology for monitoring LNAPL mainly relies on regular water quality testing, or uses a beehive to check when the water quality is obviously abnormal. Existing patent documents also focus on proposing complete remediation plans after the pollution is discovered. The remediation plans are mostly deterministic and cannot be effectively adjusted according to changes in pollution. Pollution remediation also focuses on a single remediation technology. The entire process often requires groundbreaking and expert demonstration before it can be carried out. Therefore, it is very easy to delay the treatment time and cause the migration of pollution. The present invention has achieved a high degree of automation in monitoring and remediation. Based on the transformation of existing monitoring wells, it can achieve a rapid response to LNAPL pollution, make remediation adjustments according to pollution changes, and conduct simple assessments. It effectively reduces health and environmental risks before implementing a large-scale remediation plan, which is of great significance.
