Technical Field

[0003] The present application relates to the technical field of risk management and control of contaminated sites, and in particular to a method, system, device and computer equipment for determining a pollutant control strategy. Background Art

[0004] Groundwater pollution at industrial sites, such as chemical production, waste disposal, and metal smelting, is often hidden, chronic, and difficult to recover from. This contamination is difficult to detect and expensive to remediate, presenting a significant environmental challenge. These pollutants are generally biotoxic, environmentally persistent, and bioaccumulative, posing a serious threat to the groundwater environment and human health. Therefore, intelligent management and control of groundwater contaminants is a key research priority.

[0005] Currently, intelligent management and control of groundwater pollutants involves monitoring the current groundwater pollution situation and then using a pollution trend prediction model to conduct intelligent management and control of groundwater pollutants. However, pollution trend prediction models are often generated based on historical water body data, and their prediction accuracy varies for different water bodies. When intelligent management and control is based on these prediction models, pollution plume leaks are prone to occur. This results in poor control and control of different groundwater pollutants.

[0066] In order to make the purpose, technical solutions and advantages of this application more clear, the following further describes this application in detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not intended to limit this application.

[0067] The method for determining a pollutant control strategy provided in an embodiment of the present application can be applied in an application environment for groundwater pollutant control as shown in Figure 1. The method is applied to a system for determining a pollutant control strategy, which includes a head pressure monitoring subsystem, a groundwater extraction subsystem, a groundwater directional injection subsystem, a flow monitoring subsystem, a pollutant monitoring subsystem, and a control center subsystem. The control center subsystem is connected to the head pressure monitoring subsystem, the groundwater extraction subsystem, the groundwater directional injection subsystem, the flow monitoring subsystem, and the pollutant monitoring subsystem, respectively. The head pressure monitoring subsystem is connected to the groundwater extraction subsystem and the groundwater directional injection subsystem, respectively. The method for determining a pollutant control strategy is applied to the control center subsystem, which can be a terminal. The terminal can be, but is not limited to, various personal computers, laptops, smartphones, tablets, etc. The terminal collects water data from different locations of the contaminated water body to analyze the pollutant distribution information of the contaminated water body. Then, by collecting water flow information and pollutant distribution information of the contaminated water body, it generates and controls the pollutant control strategy determination system to execute instructions corresponding to the pollutant control strategy. Then, by adjusting the pollutant control strategy in real time, we ensure intelligent control of pollutant treatment in the polluted water body. This solution generates a pollutant control strategy for the polluted water body in real time based on pollutant distribution information and water flow information. By real-time monitoring of the current water body data of the polluted water body, we adjust the pollutant control strategy, improving the targeted intelligent pollutant treatment for different polluted water bodies, thereby improving the pollutant control effect of different groundwater pollution.

[0068] In one embodiment, as shown in FIG2 , a method for determining a pollutant control strategy is provided. The method is described by taking the application of the method to a terminal as an example, and includes the following steps S201 to S204 .

[0069] Step S201 : obtaining water body data of different locations of polluted water bodies and historical sample water body data of different pollution degrees, and identifying pollutant distribution information of the polluted water bodies based on each historical sample water body data and each water body data of the different locations.

[0070] In this embodiment, the terminal receives water body data of different locations of the polluted water body transmitted by the pollutant monitoring system. The pollutant detection subsystem includes samplers evenly set at different locations in the groundwater body, and based on the samplers at different locations, the water body data of different locations of the polluted water body in the groundwater body are collected. Then, the terminal filters the sample water body data of different pollution levels in the historical water body database as historical sample water body data of different pollution levels. Then, based on each historical sample water body data, the terminal identifies the sub-pollution level of the water body data of each location point, thereby obtaining the pollutant distribution information of the polluted water body. The pollutant distribution information is used to characterize the water body area of ​​the polluted water body corresponding to the different pollution levels of the polluted water body. The specific identification process will be described in detail later, wherein the setting location points of each sensor in the pollutant detection subsystem are location points preset by the staff.

[0071] Step S202 : collecting water flow information of the polluted water body, and generating a pollutant control strategy for the polluted water body based on the water flow information of the polluted water body and the pollutant distribution information of the polluted water body.

[0072] In this embodiment, the terminal receives water flow information from a contaminated water body transmitted by a flow monitoring subsystem. The flow monitoring subsystem includes water flow pressure sensors and flow direction sensors uniformly located at different locations within the groundwater body. Based on these sensors, the terminal determines the water flow information of the contaminated water body. This water flow information includes the hydraulic gradient of the groundwater aquifer and the direction of groundwater flow. The hydraulic gradient is the gradient distribution of water flow pressure detected by the flow sensors at different locations. The terminal then generates a pollutant control strategy for the contaminated water body based on the water flow information and the pollutant distribution information within the contaminated water body. This pollutant control strategy includes sub-pollutant control strategies for different contaminated areas within the contaminated water body. Each sub-pollutant control strategy is designed to prevent the spread of the contamination plume within that contaminated area and to treat the pollutants within that area. The specific treatment process and the process of generating the pollutant control strategy for the contaminated water body will be described in detail later. The contamination plume is the annular area surrounding all pollutants in the contaminated water body.

[0073] Step S203: executing the pollutant control strategy and detecting the water body data change information at each of the different locations.

[0074] In this embodiment, the terminal implements the pollutant control strategy through a groundwater extraction subsystem and a groundwater directional injection subsystem. Staff construct multiple extraction wells arranged in a fixed pattern within the groundwater area. These wells are connected to a pumping pipeline, which is then connected by a main pipe and leads to the contaminated groundwater treatment system. Each groundwater extraction subsystem includes a pump installed in each extraction well, and the groundwater directional injection subsystem includes an injection pump installed in each extraction well. The pump is used to extract pollutants from the contaminated water body, thereby preventing the contamination plume from spreading in the direction of the water flow. The injection pump is used to inject a high-pressure fluid, primarily water, into the contaminated water body. This high-pressure fluid then prevents the contamination plume from continuing to spread in the direction of the water flow. The groundwater extraction subsystem and the groundwater directional injection subsystem form a hydraulically connected channel in the groundwater through the pumps and injection pumps. Based on the generated pollutant control strategy, the groundwater extraction subsystem and the groundwater directional injection subsystem select a portion of the extraction wells as vacuum extraction capture wells. These perform vacuum extraction simultaneously with high-pressure injection, creating a low-pressure zone and providing directional guidance for the high-pressure injected fluid. The orientation of the sieve holes in the groundwater directional injection subsystem's screen tubes is determined by the location of the vacuum extraction capture wells, enhancing the directionality of high-pressure injection and ensuring the successful construction of a hydraulic interconnection channel. This hydraulic interconnection channel ensures that the contamination plume can be contracted along the direction of the water interconnection channel, thereby preventing the contamination plume from spreading. The terminal then uses the current water data transmitted by the pollutant monitoring subsystem for each location and identifies changes between the current water data and the initially collected water data to obtain water data change information.

[0075] Step S204: Based on the water body data change information of each of the different location points, the pollutant control strategy of the polluted water body is adjusted to obtain a new pollutant control strategy, and the new pollutant control strategy is used to replace the pollutant control strategy. The steps of executing the pollutant control strategy and detecting the water body data change information of each of the different location points are iteratively executed until the current water body data of each of the different location points meets the standard water body conditions, and the iterative operation is stopped.

[0076] In this embodiment, the terminal adjusts the pollutant control strategy for the polluted water body based on the water body data change information at each location, obtaining a new pollutant control strategy. The specific adjustment process will be described in detail later. The terminal then replaces the pollutant control strategy with the new pollutant control strategy and iteratively executes the steps of executing the pollutant control strategy and detecting water body data change information at each of the different locations until the current water body data at each location meets the standard water body condition, at which point the iterative operation ceases. The standard water body condition is that the pollution level of the current water body data at each location is less than a pollution level threshold preset in the terminal.

[0077] Based on the above scheme, by collecting water data from different locations of the polluted water body, the pollutant distribution information of the polluted water body is analyzed, and then by collecting the water flow information and the pollutant distribution information of the polluted water body, the system for determining the pollutant control strategy is generated and controlled to execute the instructions corresponding to the pollutant control strategy. Then, by adjusting the pollutant control strategy in real time, the pollutant treatment of the polluted water body is ensured to be intelligently controlled. This scheme generates the pollutant control strategy of the polluted water body in real time through the pollutant distribution information and water flow information of the polluted water body, and adjusts the pollutant control strategy by real-time monitoring of the current water body data of the polluted water body, thereby improving the targeted intelligent pollutant treatment of different polluted water bodies, thereby improving the pollutant control effect of different groundwater pollution.

[0078] Optionally, based on each historical sample water body data and the water body data of each location point, the pollutant distribution information of the polluted water body is identified, including: in each historical sample water body data, identifying the target historical sample water body data corresponding to the water body data of each location point, and using the pollution degree of each target historical sample water body data as the pollution degree corresponding to the water body data of each location point; identifying the relative position information between each location point, and generating the pollutant distribution information of the polluted water body based on the relative position information and the pollution degree corresponding to the water body data of each location point.

[0079] In this embodiment, the terminal identifies the target historical sample water data corresponding to each location point in the historical sample water data, and uses the pollution level of each target historical sample water data as the pollution level corresponding to the water data at each location point. The terminal then identifies the relative position information between each location point and, based on the relative position information and the pollution level corresponding to the water data at each location point, generates pollutant distribution information for the polluted water body. The pollutant distribution information is generated by performing interval image fitting on the pollution level at each location point to obtain the pollutant distribution information. Specifically, based on the pollution level at each location point and the relative position information between each location point, the terminal uses a two-dimensional plane image recognition strategy to identify the location information corresponding to the pollution center point of the polluted water body. The terminal then constructs a circular range for each pollution level of the polluted water body, with the pollution center point as the center and the straight-line distance between each location point and the pollution center as the radius, thereby obtaining the pollutant distribution information for the polluted water body. This pollutant distribution information is constrained by the groundwater boundary: that is, the boundaries of the pollutant distribution information are the circular ranges corresponding to each pollution level relative to the water flow direction and the shore boundary perpendicular to the water flow direction. The two-dimensional plane image recognition strategy is that the terminal constructs a two-dimensional coordinate system containing each location point based on the relative position information between each location point, and then the terminal identifies the direction of increasing pollution levels between each location point based on the pollution level of each location point. Afterwards, the terminal uses the position information corresponding to the intersection of the extended straight lines in the direction of increasing pollution levels of all location points as the position information corresponding to the pollution center point.

[0080] Based on the above scheme, the location information corresponding to the pollution center is determined through the relative location information of each location point and the pollution degree of each location point. Then, the pollutant distribution information of the polluted water body is constructed, which improves the accuracy of constructing the pollutant distribution information of the polluted water body.

[0081] Optionally, based on the water flow information of the polluted water body and the pollutant distribution information of the polluted water body, a pollutant control strategy for the polluted water body is generated, including: identifying the hydraulic gradient of the polluted water body and the water flow direction of the polluted water body based on the water flow information, and identifying the diffusion direction of the polluted water body and the diffusion rate of the polluted water body based on the hydraulic gradient of the polluted water body, the water flow direction of the polluted water body, and the pollutant distribution information of the polluted water body; dividing the polluted water body into different pollution areas based on the diffusion direction of the polluted water body and the diffusion rate of the polluted water body, obtaining pollution diffusion information corresponding to different pollution areas, and identifying the pollution degree corresponding to each pollution area; for each pollution area, based on the pollution degree corresponding to the pollution area and the pollution diffusion information corresponding to the pollution area, querying the sub-pollution control strategy corresponding to the pollution area in the pollution treatment strategy database, and using the sub-pollution control strategies corresponding to all pollution areas as the pollutant control strategy for the polluted water body.

[0082] In this embodiment, the terminal identifies the hydraulic gradient and flow direction of the polluted water body based on water flow information. Furthermore, based on the hydraulic gradient, flow direction, and pollutant distribution information of the polluted water body, it identifies the diffusion direction and diffusion rate of the polluted water body. The diffusion direction of the polluted water body is the same as the flow direction of each region of the polluted water body, and the diffusion rate of the polluted water body is the diffusion speed of each region as shown in the pollutant distribution information. The terminal then divides the polluted water body into different polluted areas based on the diffusion direction and diffusion rate, and obtains pollution diffusion information corresponding to each polluted area. Specifically, the terminal classifies areas with the same diffusion direction and diffusion rates that differ by no more than a preset deviation threshold as a single polluted area. The terminal then identifies the pollution level corresponding to each polluted area. Each polluted area may contain one or multiple pollution levels. If a polluted area contains multiple pollution levels, the terminal uses the maximum pollution level among the pollution levels as the pollution level corresponding to that area.

[0083] For each polluted area, based on the pollution level and pollution diffusion information corresponding to the polluted area, the pollution treatment strategy database is searched for the corresponding sub-pollution control strategy for the polluted area. The sub-pollution control strategies corresponding to all polluted areas are used as the pollutant control strategy for the polluted water body. Each sub-pollution control strategy corresponds to a diffusion rate range and a pollution level range. The terminal identifies the diffusion rate range to which each pollution area's diffusion rate belongs and the pollution level range to which each pollution area's pollution level belongs, and determines the sub-pollution control strategy corresponding to each pollution area.

[0084] Specifically, the sub-pollution control strategy is determined by the terminal, which determines the comprehensive pumping rate and high-pressure injection rate for the contaminated area based on the diffusion rate, diffusion direction, and contamination level of the contaminated area. The terminal then identifies the number of extraction wells within the contaminated area, the location of each extraction well, the unit pumping rate for each extraction well, the unit high-pressure injection rate for each extraction well, and the ratio between the number of extraction wells required by the groundwater directional injection subsystem and the number of vacuum extraction capture wells.

[0085] Next, the terminal divides the comprehensive pumping rate of the contaminated area by the unit pumping rate of the extraction well to obtain a first number of extraction wells required by the groundwater extraction subsystem in the contaminated area. It also divides the comprehensive high-pressure water injection rate of the contaminated area by the unit high-pressure water injection rate of the extraction well to obtain a second number of extraction wells required by the groundwater directional injection subsystem in the contaminated area. Next, based on the ratio between the number of extraction wells required by the groundwater directional injection subsystem and the number of vacuum extraction capture wells, the terminal calculates a third number of vacuum extraction capture wells corresponding to the second number.

[0086] From the extraction wells within the contaminated area, the terminal selects a first number of extraction wells at the beginning of the contaminated area's diffusion direction as the pumping wells required by the groundwater extraction subsystem; selects a third number of extraction wells at the beginning of the contaminated area as the vacuum extraction capture wells; and selects a second number of extraction wells at the end of the contaminated area's diffusion direction as the injection wells required by the groundwater directional injection subsystem within the contaminated area. Finally, the terminal uses the location information of each pumping well, each injection well, each vacuum extraction capture well, and each well as the sub-pollution control strategy for the contaminated area.

[0087] Based on the above scheme, by identifying water flow information, the polluted water body is divided, and the sub-pollution control strategy of each polluted area is determined, thereby improving the pollutant control effect in different polluted areas.

[0088] Optionally, based on the water body data change information of each location point, the pollutant control strategy of the polluted water body is adjusted to obtain a new pollutant control strategy, including: based on the water body data change information of each location point, identifying the current pollutant distribution information of the polluted water body, and returning to execute the step of collecting water flow information belonging to the polluted water body to obtain a new sub-pollution control strategy corresponding to each new pollution area of ​​the polluted water body; the terminal uses the new sub-pollution control strategies corresponding to all new pollution areas as the new pollutant control strategy for the polluted water body.

[0089] In this embodiment, the terminal determines the new water body data of each location point based on the water body data change information of each location point, and identifies the current pollutant distribution information of the polluted water body based on the water body data of each historical sample and the new water body data of each location point. Then, the terminal returns to execute the step of collecting the water flow information of the polluted water body to obtain the new sub-pollution control strategy corresponding to each new pollution area of ​​the polluted water body. Finally, the terminal uses the new sub-pollution control strategy corresponding to all new pollution areas as the new pollutant control strategy of the polluted water body. Among them, after the pollutants are extracted, the density of the current polluted water body decreases, so the flow speed of the groundwater to which the current polluted water body belongs will also accelerate. Therefore, it is necessary to re-collect the water flow information of the polluted water body and re-determine each pollution area.

[0090] Based on the above scheme, by real-time detection of water body data change information of the current polluted water body, the new pollution area and the new sub-pollution control strategy corresponding to the new pollution area are adjusted, thereby improving the intelligent management and control effect of the polluted water body, thereby improving the management and control efficiency of the polluted water body.

[0091] Optionally, the iterative operation is stopped until the current water body data of each location point meets the standard water body condition, including: for each location point, taking the current water body data of the location point, and identifying the first historical sample water body data corresponding to the current water body data of the location point in each historical sample water body data, and using the pollution level of the first historical sample water body data as the pollution level corresponding to the current water body data of the location point; judging whether there is a pollution level greater than a pollution level threshold; and stopping the iterative operation if there is no pollution level greater than the pollution level threshold.

[0092] In this embodiment, for each location point, the terminal obtains the current water body data of the location point and identifies the first historical sample water body data corresponding to the current water body data of the location point from each historical sample water body data. The pollution level of the first historical sample water body data is used as the pollution level corresponding to the current water body data of the location point. The terminal then determines whether there is a pollution level greater than a pollution level threshold. The pollution level threshold is preset in the terminal. If there is no pollution level greater than the pollution level threshold, the iterative operation is stopped. If there is a pollution level greater than the pollution level threshold, the terminal iteratively executes the steps of executing the pollutant control strategy and detecting water body data change information for each of the different location points until there is no pollution level greater than the pollution level threshold.

[0093] Based on the above scheme, by determining the iterative termination conditions, energy waste is avoided, thereby improving the energy optimization effect and intelligence level of the method for determining the pollutant control strategy.

[0094] In one embodiment, as shown in FIG1 , a system for determining a pollutant control strategy is provided, characterized in that the system includes a water head pressure monitoring subsystem, a groundwater extraction subsystem, a groundwater directional injection subsystem, a flow monitoring subsystem, a pollutant monitoring subsystem, and a control center subsystem. The control center subsystem is connected to the water head pressure monitoring subsystem, the groundwater extraction subsystem, the groundwater directional injection subsystem, the flow monitoring subsystem, and the pollutant monitoring subsystem, respectively. The water head pressure monitoring subsystem is connected to the groundwater extraction subsystem and the groundwater directional injection subsystem, respectively. The flow monitoring subsystem is used to collect water flow information belonging to the polluted water body, and transmit the water flow information belonging to the polluted water body to the control center subsystem. The pollutant monitoring subsystem is used to collect water body data at different locations of the polluted water body, and transmit the water body data at different locations of the polluted water body to the control center subsystem. The groundwater extraction subsystem and the groundwater directional injection subsystem are used to receive the pollutant control instructions containing the execution of pollutant control strategies transmitted by the control center subsystem, and execute the pollutant control strategies in the pollutant control instructions; the head pressure monitoring subsystem is used to detect the execution information of the groundwater extraction subsystem and the groundwater directional injection subsystem on the pollutant control instructions, as well as the operation information of the groundwater extraction subsystem and the groundwater directional injection subsystem, and transmit the execution information and the operation information of the groundwater extraction subsystem and the groundwater directional injection subsystem to the control center subsystem; the control center subsystem is used to execute the method for determining the pollutant control strategy.

[0095] Preferably, the groundwater directional injection subsystem includes a vacuum extraction subsystem and an injection pump, and the groundwater extraction subsystem includes a pumping pump. The injection pump of the groundwater directional injection subsystem, the pumping pump of the groundwater extraction subsystem, and the vacuum extraction subsystem are arranged in the same extraction well. The number of extraction wells is greater than three, and one extraction well cannot simultaneously perform tasks corresponding to two or more subsystems. The groundwater directional injection subsystem is used to identify the extraction well corresponding to the injection well and the extraction well corresponding to the vacuum extraction capture well in each extraction well based on the pollutant control instruction, and simultaneously start the injection pump in the extraction well corresponding to the injection well and the vacuum pumping device of the extraction well corresponding to the vacuum extraction capture well. The groundwater extraction subsystem is used to identify the extraction well corresponding to the pumping well in each extraction well based on the pollutant control instruction, and start the pumping pump of the extraction well corresponding to the pumping well. The head pressure monitoring subsystem includes a water flow pressure sensor and a flow direction sensor, and the flow monitoring subsystem includes a water flow pressure sensor. The water flow pressure sensor and flow direction sensor of the head pressure monitoring subsystem and the water flow pressure sensor of the flow monitoring subsystem are arranged in the same extraction well.

[0096] Preferably, the water injection pump is used to inject high-pressure water into the contaminated water body, and the vacuum pumping device is used to perform a vacuum extraction operation on the contaminated water body to generate a low-pressure zone, and based on the low-pressure zone and the high-pressure water body, a hydraulic communication channel is generated to guide the high-pressure water body, and the contaminated water body is injected into the contaminated water body through the hydraulic communication channel. In the case where the extraction well is an injection well, the extraction well opens a directional sieve hole, and the directional sieve hole is used to guide the injection direction of the high-pressure water body. The hole spacing d of the directional sieve hole is less than 5cm, wherein the terminal presets a hole spacing threshold, which is 5cm. The outside of the directional sieve hole is wrapped with a protective net, which is used to prevent pollutants from blocking the directional sieve hole, thereby protecting the water injection operation of the high-pressure water body. The direction of the directional sieve hole is determined by the direction of the extraction well corresponding to the vacuum extraction capture well relative to the extraction well corresponding to the injection well. The extraction well includes a first well section exposed to the air and a second well section in the water body. Based on the air-bearing zone height H1 of the first well section and the aquifer thickness H2 corresponding to the second well section, the pressure P of the high-pressure fluid injection of the water injection pump and the pumping pressure P' of the water pump are determined; the pressure P of the high-pressure fluid injection satisfies the drawdown of P>ρg(1.7H1+H2), and the pumping pressure P' satisfies the drawdown of P'>H2 / 2.

[0097] Specifically, as shown in Figure 1, the control center subsystem (hereinafter referred to as the system) consists of the following parts: a data receiving device, a human-machine interface, a control module, a network server, and a remote login interface. The data receiving device collects data in real time from the head pressure sensors and water pump flow meters installed at various locations of the pollution plume, and at the same time receives real-time sensor or laboratory analysis data in combination with the pollutant monitoring system. The received data is transmitted to the control module, which performs calculations and logical judgments based on real-time data and historical data to control the extraction pump and injection pump. The data collected by the data receiving device and the commands sent by the control module are also transmitted to the human-machine interface and the network server in real time and stored. The network server can be browsed and operated through the remote login interface. Staff can command the control module through the human-machine interface or the remote login interface.

[0098] As shown in Figure 3, the system constructs multiple extraction wells evenly distributed at different locations within the contaminated water body. Each extraction well is connected to a pumping pipeline, which in turn is connected by a main pipeline to the contaminated groundwater treatment system. The extraction wells include hydraulic head sensors, pumps, injection pumps, directional screens, and protective nets. The hydraulic head sensors include a flow pressure sensor and a flow direction sensor. The flow pressure sensor is connected to the flow detection subsystem and the hydraulic head pressure monitoring subsystem, respectively, while the flow direction sensor is connected to the hydraulic head pressure detection subsystem. All sensors are connected to the control center subsystem via data cables. As shown in Figure 4, the high-pressure injection subsystem is connected to the vacuum extraction subsystem and the injection pump via control lines to execute pollutant control commands. The groundwater directional injection subsystem includes two types of injection facilities. One type is extraction wells, which have both injection and extraction pipelines. During injection, the extraction pipelines in these wells are closed, while the injection pipelines are open. The other type is an injection culvert, located between adjacent extraction wells or downstream of an extraction well. Among them, the groundwater directional injection subsystem includes a water treatment subsystem. The effluent of the water treatment subsystem passes through a deep treatment device for water recharge. The effluent pipe of the water treatment subsystem is connected to the groundwater directional injection subsystem to provide water materials for the groundwater directional injection subsystem.

[0099] As shown in Figure 5, the hydraulic interconnection channel is composed of high-pressure water injected by the groundwater directional injection subsystem, the water extraction process of the groundwater extraction system, and the low-pressure zone created by the vacuum extraction capture well. The groundwater directional injection subsystem injects high-pressure fluid through some extraction wells. The fluid is mainly composed of water. Lubricating materials and pore-filling materials can be added according to the needs of the formation structure. The screen pipes of the extraction wells corresponding to the high-pressure injection wells have directional screen holes as shown in Figure 6, and the screen hole spacing d does not exceed 5cm. Some extraction wells are selected between the high-pressure injection wells as vacuum extraction capture wells. Vacuum extraction is carried out simultaneously with high-pressure injection to create a low-pressure zone and provide directional guidance for the high-pressure injected fluid. The orientation of the screen holes of the high-pressure injection well screen pipe is determined by the position of the vacuum extraction capture well to enhance the directionality of the high-pressure injection and ensure the successful construction of the hydraulic interconnection channel. As shown in Figure 7, the extraction well includes a first section exposed to air and a second section submerged in water. Based on the aeration zone height H1 of the first section and the aquifer thickness H2 corresponding to the second section, the injection pressure P of the high-pressure fluid and the pumping pressure P' of the pump are determined. The injection pressure P of the high-pressure fluid satisfies the drawdown requirement of P > ρg(1.7H1 + H2), while the pumping pressure P' satisfies the drawdown requirement of P' > H2 / 2.
