Conduct pollution analysis on the sampling results according to the preset pollution factors, and classify the pollution risk level according to the pollution analysis results and the preset risk factors. It should be noted that the preset pollution factors may include the three risk elements of "source-pathway-receptor", and the preset risk factors may include: pollutant accumulation parameters, for example: no soil pollutants exceed the standard, and there is no obvious pollutant accumulation phenomenon; the risk of groundwater pollution is extremely low, and the risk level in this case can be classified as low risk.

[0060] S5, assigning a corresponding preset treatment plan to the target area according to the pollution risk level classification result.

[0061] This plan establishes a comprehensive evaluation method for soil pollution risk levels in typical industrial parks by collecting soil environmental information of target areas in the soil environmental information database, and conducting soil pollution risk screening, sample collection, testing and analysis, and grading. It investigates and evaluates the soil environmental risk status of typical industrial parks dominated by operating enterprises, and provides countermeasures and suggestions for soil environmental management departments.

[0062] Preferably, in any of the above embodiments, it further comprises:

[0063] Soil environmental information of each region is collected through preset methods; it should be noted that the preset methods may include: collecting natural environment profiles of the target area, land use history, industrial park enterprise lists, basic information on enterprise plots, pollution source information, main products and raw and auxiliary materials, migration pathway information, sensitive receptor information, existing environmental survey and monitoring information, and other structured and unstructured multi-source and multi-dimensional data through Internet public data, satellite images, literature review, purchase of commercial data, etc.

[0064] Verify and verify soil environmental information in each region;

[0065] The verified soil environmental information shall be stored in the soil environmental information database.

[0066] It should be noted that, in a certain embodiment, the collected information can be sorted, verified and supplemented through technical methods such as on-site surveys and personnel interviews, and finally an effective soil environmental information database that can be quantitatively evaluated is formed. The basic information classification table of a typical industrial park can be shown in Table 1:

[0067]

[0068]

[0069] Table 1

[0070] This plan builds a database by collecting soil environmental information from various regions, which can form an effective soil environmental information database that can be used for quantitative evaluation.

[0071] Preferably, in any of the above embodiments, screening the soil environmental information according to the preset risk screening model specifically includes:

[0072] The soil environmental information is classified according to the first screening factor; it should be noted that the first screening factor may include: key industries.

[0073] It should be noted that, in a certain embodiment, soil pollution is classified according to key industries, as shown in Table 2, and all production enterprises in the park are identified as key focus enterprises and non-key focus enterprises, and non-key focus enterprises are identified according to the park's dominant industries and non-dominant industries.

[0079] Table 2

[0080] The classified soil environmental information is quantitatively calculated according to multiple screening indicators. It should be noted that the multiple screening indicators can include: three levels of risk screening indicators, among which the first-level indicators include pollution source conditions, pollution migration pathways, and sensitive receptors; the second-level indicators include six items: basic conditions of enterprises, pollutant hazards, enterprise management level, pollutant migration capacity, medium conditions, and sensitive receptors; the third-level indicators include 20 items, as shown in Table 3; the specific risk quantification calculation method is as follows:

[0081] Table 3 shows the classification standards for the attention level of enterprise plots. Table 4 shows the classification standards for the attention level of enterprise plots.

[0089] Total score of land risk screening Land plot attention level S≥70 points Highly concerned plots 40≤S<70 points Moderately concerned plots S<40 points Low-profile plots

[0090] Table 4

[0091] The soil environmental information after quantitative calculation is graded according to the second screening factor, and the screening is completed when the screening result is obtained. It should be noted that the second screening factor may include: dominant and non-dominant industrial agglomeration, land development history, functional area planning and road network boundaries.

[0092] In a certain embodiment, combined with the risk level screening of typical industrial park enterprises, the park is divided into three types of assessment units: high concern, medium concern, and low concern, according to factors such as dominant and non-dominant industrial clusters, land development history, functional area planning, and road network boundaries. Since the risk screening model cannot be applied to all enterprise plots in the park, and the unified attention classification standard cannot meet the management needs of different industrial parks in various places, it is necessary to organize experts with relevant work experience in the investigation and assessment of polluted plots and familiar with the situation of local enterprises, rely on professional judgment, find deviant enterprises, and give priority consideration to the division of assessment units, the number of sampling points, and the layout of sampling points in combination with actual conditions, to ensure the scientificity and rationality of risk screening results and point sampling work.

[0093] In a certain embodiment, based on the basic information investigation of the enterprise plot, according to the basic information such as the soil and groundwater pollution sources, pollutant migration pathways and sensitive receptors of the plot, a constructed risk screening index model, i.e., a preset risk screening model, is used to quantitatively calculate the relative risk level of the enterprise plot, and finally determine the attention level of the enterprise plot.

[0094] This scheme classifies soil environmental information through the first screening factor, quantifies the classified soil environmental information, and then classifies it into grades, so as to quantitatively calculate the relative risk level of the enterprise plot and finally determine the degree of attention of the enterprise plot.

[0095] According to the screening results, the number of sampling points, and the layout process of sampling points, the scientificity and rationality of risk screening results and sampling work are ensured.

[0096] Preferably, in any of the above embodiments, it further comprises:

[0097] Configure the corresponding sampling method according to different sampling parameters.

[0098] In one embodiment, sample collection and testing and analysis include: reasonably setting the number of sampling points, sampling point locations, sampling depth and testing indicators according to the evaluation unit's attention, enterprise type, enterprise layout, etc. Carry out on-site sample collection and conduct laboratory testing and analysis. Comprehensively use information survey results and sampling results to conduct pollution distribution, pollution source tracing, pollution accumulation and other analyses.

[0099] In one embodiment, configuring corresponding sampling modes according to different sampling parameters may include:

[0100] 1) Number of sampling points

[0101] Soil: The density of soil sample collection varies in different attention assessment units. Generally, the higher the risk level, the smaller the grid division of the soil environment monitoring point. According to the spatial distribution difference semi-range influence function of typical pollution such as heavy metals in conventional soil at the regional scale, the grid size of each soil environment monitoring point in the industrial park is usually no more than 400 meters × 400 meters for high-attention assessment units, no more than 800 meters × 800 meters for medium-attention assessment units, and no more than 1600 meters × 1600 meters for low-attention sampling units.

[0102] Groundwater: In principle, each industrial park should have at least five groundwater sampling points, which can be adjusted appropriately based on the actual conditions such as the size of the survey area, production layout, and hydrogeological conditions.

[0103] 2) Sampling point location

[0104] Soil: For enterprises in production, soil sampling should be as close as possible to suspected pollution sources, and should be determined without affecting the normal production of the enterprise and without causing safety hazards or secondary pollution. If the sampling conditions are not available at the selected sampling location, the sampling location should be selected in the downstream direction of the pollutant migration. For closed and relocated enterprises, soil sampling should give priority to the locations of suspected pollution sources such as production facilities, tanks, and pollution leakage points within the sampling area, and should be determined without causing safety hazards or secondary pollution.

[0105] Groundwater: The locations of sampling points are based on the Technical Specifications for Groundwater Environmental Monitoring (HJ / T164-2004) and are reasonably arranged in combination with the existing shallow pollution source monitoring wells and basic information collection of the local geological survey bureau's groundwater monitoring network.

[0106] 3) Sampling Depth

[0107] In general, the vertical soil sampling depth is:

[0108] 1) The first layer is mainly for the surface miscellaneous filling layer, and the general sampling depth is about 0.2 meters;

[0109] 2) The second layer mainly targets the lower sediment layer and the migration and diffusion layer of major pollutants, and the general sampling depth is about 1.5 meters;

[0110] 3) The third layer is mainly for areas with potential underground leakage sources such as underground pipelines and storage tanks. The sampling location is located in the first powdery layer and other strata with relatively strong barrier capabilities. The general sampling depth is about 3.5 meters. In general, the number of points for sampling the third layer of soil samples should not be less than 30% of all sampling points.

[0111] The specific sampling depth can be adjusted appropriately according to the actual situation of the site. When the vertical variation of soil layer characteristics is large, the stratum thickness is large, or there is an obvious miscellaneous fill area, the number of soil samples can be appropriately increased.

[0112] Groundwater sampling depth: Determined based on the site’s hydrogeological conditions and the characteristics of the pollution sources obtained through investigation. In general, the sampling depth can be below 0.5m from the groundwater level.

[0113] 4) Detection indicators

[0114] 1) Soil indicators: According to the industrial characteristics of the industrial park, the pollution characteristics of the key survey objects and other environmental management factors, basic soil environmental monitoring factors (45 items, basic items in GB36600-2018) and characteristic pollution factors are generally set (which can be selected from soil environmental quality standards, local standards and other reference standards according to actual conditions).

[0115] 2) Groundwater indicators: According to the industrial characteristics of the industrial park, the pollution characteristics of the key survey objects and other environmental management factors, conventional groundwater environmental monitoring factors (conventional indicators in GB / T14848-2017) and characteristic pollution factors are generally set. The specific detection factors can be appropriately adjusted according to the actual situation of the industrial park.

[0116] Sample collection, preservation and transfer shall be carried out in accordance with the "Technical Provisions on Sample Collection, Preservation and Transfer of National Key Industry Enterprise Land Use Survey (Trial)". Sample testing and analysis shall be entrusted to qualified laboratories for testing and analysis, and national standard methods and industry standard methods shall be used as testing methods.

[0117] This plan uses different sampling methods to achieve comprehensive analysis from different angles, including pollution distribution, pollution source tracing, and pollution accumulation.

[0118] Preferably, in any of the above embodiments, the sampling parameters include: the number of sampling points, the locations of the sampling points and the detection index.

[0119] This plan sets sampling parameters such as the number of sampling points, sampling point locations, and detection indicators, and comprehensively uses information survey results and sampling results to conduct analyses such as pollution distribution, pollution source tracing, and pollution accumulation.

[0120] In one embodiment, soil pollution risk classification includes: based on the relevant information of the plot and the preliminary sampling survey results, a risk classification index system and evaluation method based on the three risk elements of "source-pathway-receptor" are used, as shown in Table 5. Finally, the soil pollution risk sub-item score and comprehensive score of each industrial park are calculated comprehensively, and then the soil pollution risk level of the industrial park is finally determined based on the comprehensive score. According to the risk level of the industrial park, countermeasures and suggestions such as maintaining the status quo, prudent use and risk control are given. The specific risk classification standards and countermeasures are shown in Table 6.
