The permeability coefficient corresponding to the permeability coefficient matrix information and the intrinsic permeability of the soil skeleton are both second-order tensors.

[0225] Among them, the overlap factor information refers to the overlap range between adjacent single-well information in the multi-well information. For example, when the overlap factor information is equal to 1, the adjacent single-well information is tangent; when the overlap factor information is greater than 1, the adjacent single-well information partially overlaps; when the overlap factor information is less than 1, the adjacent single-well information does not interfere with each other.

[0227] Among them, the multi-well information refers to a larger simulated contaminated site composed of multiple single-well information according to the overlap factor information, which is designed by the interactive modeling platform according to the overlap factor information and the single-well information. The specific design method refers to Figure 7 the steps.

[0228] Step S6011: Obtain the total mass information of pollutants in the target area and the change information of the total mass of pollutants in the target area.

[0229] Among them, the total mass information of pollutants in the target area refers to the total mass of pollutants in a certain single-well information in the multi-well information, and its calculation method is the same as that of the initial total amount of pollutants information in step S10211.

[0236] Referring to Figure 7 , analyze according to the overlap factor information and the single-well information to determine the method of the multiple-well information, including the following steps:

[0237] Step S700: Obtain the remediation target concentration information of the single-well information.

[0238] Among them, the remediation target concentration information is the remediation concentration value of the pollutants in the single-well information, and the pollutant concentration corresponding to the specific remediation target concentration information is input into the interactive modeling platform by those skilled in the art.

[0239] Step S701: Judge whether the pollutant concentration information reaches the remediation target concentration information.

[0240] Among them, by judging whether the pollutant concentration value corresponding to the pollutant concentration information reaches the pollutant concentration corresponding to the remediation target concentration information, it is determined whether the influence radius information can be detected.

[0241] Step S7011: If not, continue to obtain the pollutant concentration information.

[0242] Among them, if it is determined that the pollutant concentration value corresponding to the pollutant concentration information has not reached the pollutant concentration corresponding to the remediation target concentration information, it indicates that the pollutants in the single well information have not been reduced to the target value. At this time, the influence radius information does not meet the usage requirements. Therefore, the pollutant concentration information is continuously detected.

[0243] Step S7012: If it reaches, obtain the injection stop time information.

[0244] Among them, the injection stop time information refers to the time when the pollutant concentration value corresponding to the pollutant concentration information reaches the pollutant concentration corresponding to the remediation target concentration information, which is obtained by timing with a timer.

[0247] Step S703: Analyze according to the single well information and the target concentration isosurface information to determine the influence radius information.

[0248] Among them, the influence radius information refers to the radius value at which the agent in the single well information reduces the pollutant concentration to the pollutant concentration corresponding to the remediation target concentration information, which is obtained by calculating the distance between the edge of the target concentration isosurface information and the central axis corresponding to the single well information by an interactive modeling platform.

[0249] Step S704: Analyze according to the influence radius information and the overlap factor information to determine the well spacing information.

[0250] Among them, the well spacing information refers to the distance value between the central axes corresponding to adjacent single well information in the multi-well information, which is calculated by the interactive modeling platform according to the influence radius information and the overlap factor information. The specific calculation formula is as follows:

[0253] is the influence radius information;

[0254] is the overlap factor information.

[0255] Step S705: Analyze according to the well spacing information and the single well information to determine the multi-well information.

[0256] Among them, the multi-well information refers to a contaminated site composed of well spacings corresponding to multiple single-well information separated by well spacing information. The radius of the single-well information is 2 meters, and the well spacing information is 4 meters. After the adjacent single-well information is tangent, the multi-well information is formed.

[0257] Refer to Figure 8 , when determining the removal rate information of the target pollutants in the multi-well, it also includes optimizing the overlapping factor information to determine the method for optimizing the overlapping factor. The specific method includes the following steps:

[0258] Step S800: Judge whether the removal rate information of the target pollutants in the multi-well is less than the preset reference removal rate information of the target pollutants.

[0259] Among them, the reference removal rate information of the target pollutants refers to the target value of the pollutant removal rate in the preset single-well information, which is set by those skilled in the art according to the actual situation.

[0260] By judging whether the removal rate corresponding to the removal rate information of the target pollutants in the multi-well is less than the removal rate corresponding to the reference removal rate information of the target pollutants, it is determined whether the multi-well information designed with the overlapping factor information meets the pollutant removal index of the contaminated site.

[0261] Step S801: If it is not less than, define the overlapping factor information as the optimized overlapping factor information.

[0262] Among them, if the removal rate corresponding to the removal rate information of the target pollutants in the multi-well is not less than the removal rate corresponding to the reference removal rate information of the target pollutants, it indicates that the multi-well information designed with the overlapping factor information meets the pollutant removal index of the contaminated site. Therefore, the overlapping factor information is defined as the optimized overlapping factor information.

[0263] Step S802: If it is less than, obtain the pollutant removal weighted value information and the reagent utilization weighted value information.

[0264] Among them, the pollutant removal weighted value information refers to the importance of the pollutant removal rate in the repair index, and the reagent utilization weighted value information refers to the importance of the reagent utilization rate in the repair index. The pollutant removal weighted value information and the reagent utilization weighted value information are both set by those skilled in the art according to the actual situation.

[0265] If the removal rate corresponding to the removal rate information of the target pollutants in the multi-well is less than the removal rate corresponding to the reference removal rate information of the target pollutants, it indicates that the multi-well information designed with the overlapping factor information does not meet the pollutant removal index of the contaminated site. Therefore, it is necessary to adjust the overlapping factor information.

[0266] Step S803: Analyze based on the multi-well target pollutant removal rate information, pollutant removal weighting value information, remediation agent utilization rate information, and agent utilization weighting value information to determine the optimized objective function information.

[0267] Among them, the optimized objective function information refers to the objective function for obtaining the optimized overlap factor information using the weighted summation method, which is calculated by the interactive modeling platform based on the multi-well target pollutant removal rate information, pollutant removal weighting value information, remediation agent utilization rate information, and agent utilization weighting value information.

[0268]

[0269] Among them, is the optimized objective function information;

[0270] is the pollutant removal weighting value information;

[0271] is the multi-well target pollutant removal rate information;

[0272] is the agent utilization weighting value information;

[0273] is the remediation agent utilization rate information.

[0274] Step S804: Obtain the overlap factor range information.

[0275] Among them, the overlap factor range information refers to the interval value of the overlap factor, which is set by those skilled in the art according to the actual situation. For example, the overlap factor ranges from 0.66 to 1.3, etc.

[0276] Step S805: Analyze based on the overlap factor range information and the optimized objective function information to determine the maximum value information of the objective function.

[0277] Among them, the maximum value information of the objective function refers to the maximum value of the optimized objective function information, which is calculated by the interactive modeling platform after inputting the multi-well target pollutant removal rate information and remediation agent utilization rate information corresponding to the overlap factor range information into the optimized objective function information. For example: when the agent utilization weighting value information is 0.4 and the pollutant removal weighting value information is 0.6, if the overlap factor is 1, the pollutant removal rate is 0.919971 and the agent utilization rate is 0.571139, so the objective function value is 0.780438; if the overlap factor is 1.3, the pollutant removal rate is 0.926657 and the agent utilization rate is 0.499676, so the objective function value is 0.755865. Thus, when the overlap factor is 1 and 1.3, the maximum value information of the objective function is 0.780438.

[0278] Step S806: Determine the optimized overlapping factor information corresponding to the maximum value information of the objective function according to the maximum value information of the objective function.

[0279] Among them, the optimized overlapping factor information refers to the overlapping factor obtained by comprehensively considering the removal rate information of the target pollutants in multiple wells and the utilization rate information of the remediation agent. For example, if the maximum value information of the objective function is 0.780438, the optimized overlapping factor information corresponding to the maximum value information of the objective function is 1.
