Description

Technical Field

[0001] This application relates to the field of soil pollution assessment, and in particular to a method for setting up identification points for the hazardous characteristics of polluted soil, an identification method, and related devices. Background Technology

[0002] Soil pollution refers to the phenomenon where toxic and harmful pollutants generated by human activities enter the soil and accumulate to a certain level, causing soil quality deterioration and reduced function, thus posing adverse effects and harm to people and crops. Soil pollution not only causes a serious waste of soil resources and hinders urbanization and socio-economic development, but also seriously threatens the health of local residents and surrounding populations, severely impacting local ecological environment construction and restoration.

[0003] In the process of remediating contaminated soil, it is necessary to identify the hazardous waste characteristics of the contaminated soil. Currently, most methods for identifying the hazardous waste characteristics of contaminated soil are based on relevant standards and specifications for the identification of hazardous waste characteristics of solid waste, and there is no specific method for identifying the hazardous waste characteristics of contaminated soil.

[0004] However, most existing methods for identifying the hazardous characteristics of solid waste employ a random sampling approach. While a higher sampling density can help refine the distribution of hazardous waste characteristics in contaminated soil, it incurs significant time, labor, and economic costs, and also increases the possibility of unrepresentative samples being included. Conversely, using a sparse sampling density that only meets the minimum sample size requirement can save costs, but may introduce substantial errors in determining the distribution of hazardous waste in the contaminated soil identification area.

[0005] Furthermore, soil pollution occurs both at specific points and across areas, exhibiting a watershed-like and regionalized development trend during its later spread. Therefore, in existing technologies, when assessing the hazardous characteristics of soil pollution according to relevant standards and specifications for solid waste hazardous waste identification, regardless of whether uniform or random sampling methods are used, the spatial heterogeneity of soil pollutant distribution can cause errors in the assessment, easily leading to the omission of areas with hazardous waste characteristics and incorrect identification of such areas. Summary of the Invention

[0006] The main purpose of this application is to propose a method for setting up identification points for hazardous characteristics of contaminated soil, an identification method, and related devices, in order to solve the problem in the prior art that when using the identification method for hazardous characteristics of solid waste to identify hazardous characteristics of soil, it is difficult to determine the number of identification points to be set up, and the results do not conform to the soil diffusion pattern.

[0030] Hazardous waste characteristics were identified from soil samples collected at each of the identification points.

[0031] Based on the total number of soil samples identified and the number of samples exceeding the hazardous waste characteristic identification standard, it is determined whether the contaminated soil in the area to be identified belongs to hazardous waste.

[0032] In this embodiment of the application, the sampling depth when collecting soil samples at any identification point is the same as the sampling depth when the pollution exceeding the standard point corresponding to that identification point is determined to be polluted.

[0033] Thirdly, this application also proposes a device for deploying identification points for the hazardous characteristics of contaminated soil, comprising:

[0077] The realization of the purpose, functional features and advantages of this application will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0078] The principles and spirit of this application will now be described with reference to several exemplary embodiments. It should be understood that these embodiments are provided merely to enable those skilled in the art to better understand and implement this application, and are not intended to limit the scope of this application in any way. Rather, these embodiments are provided to make this disclosure more thorough and complete, and to fully convey the scope of this disclosure to those skilled in the art.

[0079] Those skilled in the art will recognize that embodiments of this application can be implemented as an apparatus, device, method, or computer program product. Therefore, this disclosure can be specifically implemented in the following forms: entirely hardware, entirely software (including firmware, resident software, microcode, etc.), or a combination of hardware and software.

[0080] According to the embodiments of this application, a method for setting up identification points for the hazardous characteristics of contaminated soil, an identification method, and related devices are proposed.

[0081] Exemplary methods

[0082] In this exemplary embodiment, a method for arranging identification points for the hazardous characteristics of contaminated soil is proposed, such as... Figure 1 As shown, the method for setting up identification points for the hazardous characteristics of contaminated soil includes the following steps S100-S300:

[0083] Step S100: Obtain the location, number, and quality of each pollution exceeding the standard point within the area to be identified.

[0084] In this embodiment of the application, the area to be identified is a soil-contaminated area that requires identification of hazardous waste characteristics.

[0085] In this embodiment, information representing the pollution situation in the area to be identified, such as the location and number of pollution exceeding the standard points, the pollution factors at each pollution exceeding the standard point location, and the pollution degree of each pollution exceeding the standard point, can be obtained in advance. For example, according to the existing pollution exceeding the standard detection method, random or uniform sampling can be carried out in the area to be identified, and whether the pollution exceeds the standard can be detected. If the pollution exceeds the standard, it is a pollution exceeding the standard point.

[0086] In addition, pollutants are various pollutants that cause soil pollution. For example, if a pollution point is contaminated by arsenic, cadmium, lead, nickel, mercury, manganese, and zinc, then arsenic, cadmium, lead, nickel, mercury, manganese, and zinc are the pollutants of that pollution point, and the number of pollutants at that pollution point is 7. The degree of pollution at that pollution point can be represented by the sum of the contents of each pollutant. The higher the sum of the contents of each pollutant, the higher the degree of pollution at that pollution point.

[0087] In this embodiment of the application, the mass of the contaminated soil in the area to be identified can be obtained through measurement and calculation. For example, the area and density of the contaminated soil in the area to be identified can be measured to obtain the mass of the contaminated soil.

[0088] Step S200: Based on the quality of the contaminated soil, determine the minimum number of samples for the area to be identified.

[0089] In step S100, the quality of the contaminated soil has been determined. In this embodiment of the application, the minimum number of samples for the area to be identified can be determined according to Table 1 below.

[0090] Table 1

[0091]

[0092] In step S100, the area of ​​the region to be identified can be obtained by measurement, and the soil mass of the region to be identified can be calculated based on the soil density of the region to be identified. After obtaining the soil mass q of the region to be identified, the minimum number of samples for the region to be identified can be determined by comparing it with Table 1 above. The minimum number of samples represents the minimum number of samples required for the region to be identified.

[0093] Step S300: Based on the relationship between the number of pollution exceeding the standard points and the minimum number of samples, and the location of each pollution exceeding the standard point, identification points are set up.

[0094] In this embodiment of the application, after determining the relationship between the number of pollution exceeding the standard points in the area to be identified and the minimum number of samples in the area to be identified, identification points can be set up based on the following three situations, as follows:

[0095] Scenario 1: The number of pollution exceeding the standard is greater than the minimum sample size.

[0096] In this embodiment of the application, the identification points can be set up according to the following steps S411-S413, as follows:

[0097] Step S411: Sort the pollution exceeding points from high to low, with the pollution level as the first priority and the number of pollution factors as the second priority.

[0098] In this embodiment of the application, when obtaining pollution information of the area to be identified in step S100, the number of pollution factors at each pollution exceeding the standard point and the pollution degree of each pollution exceeding the standard point are obtained.

[0099] Therefore, when the number of pollution exceeding the standard in the area to be identified is greater than the minimum number of samples, the pollution exceeding the standard can be sorted based on the number of pollution factors and the degree of pollution of each pollution exceeding the standard.

[0100] In the sorting process, the degree of pollution is given first priority, followed by the number of pollution factors. That is, pollution levels with higher degrees of pollution are ranked first, followed by those with lower degrees. When two or more pollution exceedance points have the same degree of pollution, they are then ranked according to the number of pollution factors at each exceedance point, with those having more pollution factors ranked first and those having fewer. When two or more pollution exceedance points have both the same degree of pollution and the same number of pollution factors, they are ranked in a tie-breaking order.

[0101] Step S412: According to the sorting, select a first preset number of pollution exceeding the standard points from the sorted pollution exceeding the standard points, wherein the first preset number is not less than the minimum number of samples.

[0102] After sorting, a first preset number of pollution exceeding the standard points are selected from each of the pollution exceeding the standard points according to the sorting. The first preset number is not less than the minimum sample size. The number of the first preset number can be the same as or greater than the minimum sample size.

[0103] Step S413: Set up identification points at the locations of each selected pollution exceeding the standard point.

[0104] In step S413, the locations of the selected pollution exceedance points are the identification point locations.

[0105] When identifying the hazardous waste characteristics of contaminated soil, it is necessary to select more representative contaminated soil as identification samples. Existing random sampling methods tend to place identification points in uncontaminated or low-contaminated locations, which can easily lead to errors in the hazardous waste characteristic identification results. In this embodiment, the various pollution exceedance points are sorted according to preset conditions, and identification points are selected from those with high pollution levels and numerous pollutants, making them more representative and thus resulting in more accurate hazardous waste characteristic identification.

[0106] Scenario 2: The number of pollution exceeding the standard is equal to the minimum number of samples mentioned above.

[0107] In this embodiment of the application, when the number of pollution exceeding the standard points is equal to the minimum number of samples, identification points can be set up based on the following step S421:

[0108] Step S421: Set up identification points at the locations of each pollution exceeding the standard point.

[0109] When the number of pollution exceeding the standard is equal to the minimum number of samples, the location of each pollution exceeding the standard is the identification point, and each pollution exceeding the standard is set as the identification point.

[0110] In this embodiment of the application, when the number of pollution exceeding the standard is the same as the minimum number of samples, selecting each pollution exceeding the standard as an identification point to identify the characteristics of hazardous waste can maintain a high level of identification accuracy while setting the minimum number of identification points.

[0111] Scenario 3: The number of pollution exceeding the standard is less than the minimum number of samples.

[0112] In this embodiment of the application, when the number of contamination exceeding the standard is less than the minimum number of samples, identification points are set up based on the following steps S431-S432:

[0113] Step S431: Taking the location of each pollution exceeding the standard point as the center, set up each radiation area according to the preset radiation radius, and each radiation area corresponds one-to-one with each pollution exceeding the standard point.

[0114] In this embodiment of the application, when the number of pollution exceeding the standard is less than the minimum number of samples, a radiation area is set at the location of each pollution exceeding the standard according to a preset radiation radius. The preset radiation radius can be 2-3 meters, that is, a circular radiation area can be set with the location of each pollution exceeding the standard as the center and according to the preset radiation radius.

[0115] Step S432: Deploy identification points based on each of the radiation areas.

[0116] In step S431, circular radiation zones have been established at each pollution exceedance point. In step S432, identification points can be deployed based on each radiation zone. When deploying identification points, the identification points for each radiation zone can be located inside the radiation zone or on the boundary of the radiation zone. The radiation radius represents the range within which the pollutant can radiate from the pollution exceedance point. Deploying hazardous waste characteristic identification points within this range conforms to the diffusion pattern of contaminated soil and can accurately reflect the hazardous waste characteristics of the soil pollution area. When the identification points are set outside the radiation range, misjudgment is likely to occur.

[0117] Additionally, it should be noted that when setting up identification points in each radiation area, the same number of identification points can be set up in each radiation area, or different numbers of identification points can be set up. The total number of identification points set up in each radiation area should be greater than or equal to the minimum number of samples.

[0118] like Figure 2 As shown, assuming Figure 2 If T1 and T11 are pollution exceedance points, then a radiation zone with a radius of 3 meters is set up centered on T1 and T11, resulting in two circular radiation zones. Identification points can then be set up within these two radiation zones. For example... Figure 2As shown, identification points T2, T3, T4, and T5 are set within the radiation area of ​​T1, and identification points T12 and T13 are set within the radiation area of ​​T11.

[0119] In this embodiment, a radiation zone is set up at the point where pollution exceeds the standard, and identification points are set up within the radiation zone to identify the hazardous waste characteristics of the soil samples. The layout of the identification points is more in line with the development trend of soil pollution, and therefore the identification accuracy is relatively high.

[0120] In existing technologies, pollution exceeding the standard points in the area to be identified are only used to indicate that the area is polluted. When identifying hazardous waste characteristics, identification points are still randomly or uniformly distributed in the area to be identified, and soil samples are collected at these points. The hazardous waste characteristics are then identified based on the soil samples, thereby determining the hazardous waste characteristics of the area to be identified. For example... Figure 3 As shown, after determining the location of the pollution exceeding the standard point in the area to be identified, the existing technology still divides the area into a grid, and then randomly or uniformly places points in each grid and samples them to identify the characteristics of hazardous waste.

[0121] In this embodiment, the number of pollution exceeding the standard points and the minimum number of samples within the area to be identified are used to determine the sampling points. For example... Figure 4 As shown, when the number of pollution exceeding the standard is greater than the minimum number of samples, some of the pollution exceeding the standard are selected as identification points and soil samples are taken to identify the characteristics of hazardous waste; for example... Figure 5 As shown, when the number of pollution exceeding the standard is the same as the minimum number of samples, all pollution exceeding the standard are used as identification points, and soil samples are taken to identify the characteristics of hazardous waste; for example... Figure 6 As shown, when the number of pollution exceeding the standard is less than the minimum number of samples, a radiation zone is set up at the location of the pollution exceeding the standard, and identification points are set up within the radiation zone and soil samples are taken to identify the characteristics of hazardous waste.

[0122] Soil pollution exhibits spatial heterogeneity, meaning its development trend is uneven and complex in spatial distribution. Existing technologies, whether using random or uniform sampling, may result in sampling points being placed in uncontaminated locations or overlooking contaminated areas. Therefore, the identification of hazardous waste characteristics is prone to significant bias. To avoid omissions or misjudgments, a large number of sampling points are required, necessitating substantial human, material, and financial resources. This application, however, sets up sampling points around the location of the pollution exceedance point, or within its radiation area, based on the minimum number of samples required to meet identification requirements. Compared to existing technologies, this sampling method better reflects the diffusion pattern of soil pollution and maximizes identification accuracy with a minimal number of sampling points.

[0123] like Figure 7 As shown, in another embodiment of this application, in step S100, the water flow direction of the area to be identified can also be obtained. When the number of pollution exceeding the standard is less than the minimum number of samples, after setting the radiation area, identification points can also be set in combination with the water flow direction of the area to be identified. For example, identification points can be set downstream of the center of each radiation area according to the water flow direction.

[0124] like Figure 7 As shown, T20 is the pollution point exceeding the standard. A radiation zone with a radius of 3 meters is set out with T20 as the center. Figure 3 The arrow in the image indicates the direction of water flow in the area to be identified. When setting identification points, the diameter L perpendicular to the direction of water flow can be determined based on the direction of water flow. The diameter L must pass through the center T20. Therefore, identification points T21, T22, and T23 are set downstream of the diameter L, i.e., to the lower left.

[0125] In this embodiment, the direction of water flow in the area to be identified is more consistent with the development trend of soil pollution diffusion, thus resulting in higher identification accuracy.

[0126] Next, we will explain how to set up the identification points using specific embodiments:

[0127] In this embodiment of the application, taking a certain historical warehousing land as an example, such as... Figure 8 As shown, in step S100, the location of the pollution exceeding the standard point is determined. There are 18 pollution exceeding the standard points in the area to be identified. The area of ​​the area to be identified in the historical storage land is 12,555.40 square meters, the volume of soil pollution is 19,203.37 cubic meters, and the mass of polluted soil is 28,805.1 tons.

[0128] In step S200, according to Table 1, the mass of contaminated soil in the area to be identified in the historical storage land is 28,805.1 tons, which is greater than 1,000 tons. Therefore, the minimum number of samples in the area to be identified is 100.

[0129] In step S300, the number of contamination exceeding the standard in the area to be identified is 18, which is less than the minimum number of samples (100) for the area to be identified. Therefore, identification points can be set up in steps S431-S432. The specific locations of the identification points are as follows: Figure 8 As shown.

[0130] In another embodiment of this application, taking a steel plant as an example, such as... Figure 9As shown, in step S100, the location of the pollution exceeding the standard point is determined. There are 100 pollution exceeding the standard points in the area to be identified. The pollution factors and pollution degree of each pollution exceeding the standard point are determined. The area of ​​polluted soil in the area to be identified is 45,989.6 square meters, the volume of polluted soil is 205,083 cubic meters, and the mass of polluted soil is 307,625 tons.

[0131] In step S200, according to Table 1, the mass of contaminated soil in the area to be identified in the steel plant is 307,625 tons, which is greater than 1,000 tons. Therefore, the minimum number of samples in the area to be identified is 100.

[0132] In step S300, the number of pollution exceeding the standard points in the area to be identified is 100, which is the same as the minimum number of samples in the area to be identified, 100. Therefore, step S421 can be used to set up identification points, that is, all 100 pollution exceeding the standard points are used as identification points for identifying the characteristics of hazardous waste. The specific locations of the identification points are as follows. Figure 9 As shown.

[0133] In another embodiment of this application, taking an iron smelting plant as an example, such as... Figure 10 As shown, in step S100, the location of the pollution exceeding the standard points is determined. There are 122 pollution exceeding the standard points in the area to be identified. The area of ​​the area to be identified in the ironmaking plant is 30925.56 square meters, the volume of polluted soil is 78806.98 cubic meters, and the mass of polluted soil in the area to be identified is 118210.5 tons.

[0134] In step S200, according to Table 1, the mass of contaminated soil in the area to be identified in the historical storage land is 118210.5 tons, which is greater than 1000 tons. Therefore, the minimum number of samples in the area to be identified is 100.

[0135] In step S300, the number of contamination exceeding the standard in the area to be identified is 122, which is greater than the minimum number of samples required for the area to be identified, 100. Therefore, identification points can be set up in steps S411-S413. The specific locations of the identification points are as follows: Figure 10 As shown.

[0136] Soil pollution exhibits spatial heterogeneity, meaning its development trend is uneven and complex in spatial distribution. Existing technologies, whether using random or uniform distribution, may result in the placement of identification points in uncontaminated locations or the omission of contaminated sites, leading to significant biases in the identification of hazardous waste characteristics. To avoid omissions or misjudgments, a large number of identification points need to be set up, requiring substantial human, material, and financial resources. This application, however, sets up identification points around the location of the pollution exceedance point, either at the location of the exceedance point or within its radiation area, based on the minimum number of samples required to meet identification requirements. Compared to existing technologies, the point placement method in this application better reflects the diffusion pattern of soil pollution and maximizes identification accuracy with the minimum number of identification points required.

[0137] like Figure 11 As shown, this exemplary embodiment also proposes a method for identifying the hazardous characteristics of contaminated soil. Identification points are set up using the aforementioned method for setting up identification points for the hazardous characteristics of contaminated soil, such as... Figure 11 The method for identifying the hazardous characteristics of contaminated soil includes the following steps S500-S700:

[0138] Step S500: Collect soil samples at each of the identification points.

[0139] Based on the above-mentioned method for setting up identification points for hazardous characteristics of contaminated soil, identification points are set up in the area to be identified. In step S500, soil sampling can be carried out at each identification point. When collecting soil samples at any identification point, the sampling depth can be the same as the sampling depth of the pollution exceeding the standard point corresponding to that sampling point when obtaining its pollution information.

[0140] For example, with Figure 8 Taking a certain historical storage site as an example, as shown in Table 2 below, Table 2 is a sampling information table for identifying the hazardous waste characteristics of this historical storage site.

[0141] Table 2

[0142] Pollution exceeding standard point number Number of identification points (pieces) Sampling depth (m) Number of samples (parts) 1 5 1 5 2 5 2.0 15 3 3 2.5 9 4 3 1.5 6 5 3 6 3 6 3 2.0 6 7 3 2.5 3 8 3 1.5 3 9 3 0.5 3 10 3 2 3 11 3 2.5 9 12 3 8.0 9 13 3 8.0 9 14 3 6 3 15 3 6 3 16 3 4 6 17 3 6 3 18 3 1 3 total 58 101

[0143] For the area to be identified in the storage land, the number of pollution exceeding the standard in the area to be identified was determined when the sampling points were set up. This number is 18, which is less than the minimum number of samples of 100 for the area to be identified. Therefore, as can be seen from Table 2, there are multiple identification points in the radiation area corresponding to each pollution exceeding the standard. When sampling at each identification point, the sampling depth when collecting soil samples at any identification point is the same as the sampling depth when the pollution exceeding the standard corresponding to that identification point is determined to be pollution exceeding the standard.

[0144] For example, for pollution exceedance point 1, assuming the sampling depth when pollution exceedance point 1 is determined to exceed the standard is 1m, then the sampling depth of the 5 identification points located within the radiation area of ​​pollution exceedance point 1 when identifying hazardous waste characteristics is also 1m. Similarly, for pollution exceedance point 13, assuming the sampling depth when pollution exceedance point 13 is determined to exceed the standard is 8m, then the sampling depth of the 3 identification points located within the radiation area of ​​pollution exceedance point 13 when identifying hazardous waste characteristics is also 8m.

[0145] In this embodiment, the sampling depth of each identification point is set to be the same as the sampling depth of its corresponding pollution exceeding point when determining that its pollution exceeds the standard, which satisfies the trend of pollution soil diffusion and thus can improve the accuracy of hazardous waste characteristic identification.

[0146] Furthermore, referring to Table 2, the number of identification points deployed within the radiation areas of each pollution exceedance point varies, totaling 58 identification points, which is less than the minimum sample size of 100. Therefore, it is necessary to collect multiple soil samples at some identification points. For example, for the 5 identification points within the radiation area of ​​pollution exceedance point 2, three soil samples can be collected at each identification point. This application does not restrict which identification points to collect one soil sample or which identification points to collect multiple soil samples, as long as the total number of samples collected from all identification points is not less than the minimum sample size for the area to be identified. As shown in Table 2, for this storage land, 58 identification points were used, resulting in a total of 101 samples, which is greater than the minimum sample size of 100.

[0147] For example, with Figure 9 Taking a steel plant as an example, as shown in Table 3 below, Table 3 is a sampling information table for identifying the characteristics of hazardous waste from this steel plant.

[0148] Table 3

[0149]

[0150]

[0151] For the area to be identified in the steel plant, the number of pollution exceeding the standard within this area was determined during the sampling point layout: 100, which is equal to the minimum sample size of 100 for this area. Therefore, as shown in Table 3, each pollution exceeding the standard is considered an identification point. When sampling at each identification point, the sampling depth for collecting soil samples at each identification point is the same as the sampling depth at which the corresponding pollution exceeding the standard is determined to be polluting. Furthermore, only one soil sample needs to be collected from each identification point.

[0152] For example, with Figure 10Taking a certain ironmaking plant as an example, as shown in Table 4 below, Table 4 is a sampling information table for identifying the characteristics of hazardous waste from this ironmaking plant.

[0153] Table 4

[0154]

[0155]

[0156] For the area to be identified within the ironworks, the number of pollution exceeding the standard within this area was determined during the sampling point layout. This number was 122, which is greater than the minimum sample size of 100 for this area. Therefore, as shown in Table 4, only some pollution exceeding the standard points were used as identification points. When sampling at each identification point, the sampling depth for collecting soil samples at each identification point was the same as the sampling depth for determining the pollution exceeding the standard at the corresponding pollution exceeding the standard point. Furthermore, only one soil sample was required for each identification point.

[0157] Step S600: Identify the hazardous waste characteristics of the soil samples collected from each of the identification points.

[0158] In step S500, soil samples have been collected at each identification point. In step S600, hazardous waste characteristics can be identified based on the collected soil samples.

[0159] Step S700: Based on the total number of soil samples identified and the number of samples exceeding the hazardous waste characteristic identification standard, determine whether the contaminated soil in the area to be identified belongs to hazardous waste.

[0160] In this embodiment of the application, the determination of whether the area to be identified belongs to a hazardous waste-characteristic pollution area can be based on the following Table 5:

[0161] Table 5

[0162] Serial Number Total number of soil samples identified Excessive number of servings 1 5 2 2 8 3 3 13 4 4 20 6 5 32 8 6 50 11 7 80 15 8 ≥100 22

[0163] As shown in Table 5 above, with Figure 8 Taking the storage land shown as an example, a total of 101 soil samples were collected in step S500. In step S600, the hazardous waste characteristics of these 101 soil samples were identified. That is, the total number of soil samples identified was 101. After identification, if the number of samples exceeding the standard exceeds 22, it indicates that the area to be identified in the storage land belongs to the hazardous waste pollution area, and the polluted soil in the area to be identified in the storage land is hazardous waste. If the number of samples exceeding the standard is less than 22, it indicates that the area to be identified in the storage land belongs to the general pollution area, and the polluted soil in the area to be identified in the storage land is general pollutant.

[0164] The method for identifying the hazardous characteristics of contaminated soil in this embodiment adopts the above-mentioned method for setting up identification points. Therefore, the setting of each identification point is more in line with the diffusion trend of soil pollution, and thus the identification accuracy is high.

[0189] Based on the total number of soil samples identified and the number of samples exceeding the hazardous waste characteristic identification standard, it is determined whether the contaminated soil in the area to be identified belongs to hazardous waste.
