[0058] First, the terms involved in this application are explained:

[0059] Soil organic carbon (SOC) is a collective name for humus, plant and animal residues, and microorganisms formed by microbial action. Soil organic carbon refers to various positively charged carbon-containing organic compounds in the soil and is an extremely important component of the soil.

[0060] Heavy metal contaminated soil remediation technology refers to the removal or stabilization of heavy metal elements in the soil to a safe level through physical, chemical or biological methods.

[0061] In recent years, in the process of urbanization and industrial transfer, the relocation of industrial and mining enterprises has left behind a large number of potential contaminated sites, which has restricted the efficient circulation and utilization of urban land resources. In the process of rapid and efficient remediation of heavy metal contaminated sites, the remediation activities will inevitably bring about certain secondary environmental impacts, resource and energy consumption, and there may be over-remediation. Therefore, green, low-carbon and sustainable remediation has become the focus and inevitable trend of the site remediation industry.

[0062] In the soil remediation industry, it is specifically manifested in restoring the original carbon pool capacity of the soil and reducing energy consumption and carbon emissions during the soil remediation process. Carbon emission accounting for contaminated site remediation is considered to be an efficient and concise assessment method for judging the environmental impact and sustainability of remediation activities, and is also one of the core focuses for achieving green and sustainable remediation.

[0063] Commonly used evaluation tools usually require a large amount of data input and complex calculation processes, which may increase implementation costs and time. In addition, the built-in calculation parameters of existing calculation software are mostly not applicable to the current soil remediation industry.

[0064] At the same time, in terms of environmental indicators, the existing evaluation algorithms have relatively simple models for the early stages of carbon emissions, all focusing on environmental footprints such as energy consumption, air pollution emissions, and waste generation. They do not fully consider the environmental impacts of restoration activities on soil and ecological factors, which means that it is difficult to fully cover the entire life cycle of contaminated site restoration, and therefore there is a defect of inaccurate carbon emission calculation results.

[0065] Furthermore, natural carbon emissions account for a considerable proportion of the entire restoration process, and different restoration technologies result in different proportions of natural carbon emissions, which affects the calculation results of carbon emissions over the entire life cycle of contaminated site restoration and the establishment of subsequent recommended lists of green and low-carbon restoration technologies.

[0066] In response to the above problems, the present application provides a method for calculating carbon emissions throughout the life cycle of heavy metal contaminated site remediation and a method for determining low-carbon remediation technology, which determines the remediation technology combination corresponding to the contaminated site, and based on the remediation technology combination, determines the man-made carbon emission information corresponding to each link and the natural carbon emission information corresponding to the remediation process, determines the carbon emission parameters corresponding to the remediation technology combination according to the man-made carbon emission information corresponding to each link and the natural carbon emission information, and determines the target remediation technology combination according to the carbon emission parameters. This method combines and analyzes the man-made carbon emission information and natural carbon emission information in the remediation technology, thereby improving the accuracy of the carbon emission data of the remediation technology.

[0067] The technical solution of the present application and how the technical solution of the present application solves the above-mentioned technical problems are described in detail below with specific embodiments. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of the present application will be described below in conjunction with the accompanying drawings.

[0068] Figure 1 A process for calculating carbon emissions from the full life cycle of heavy metal contaminated site remediation provided in this application embodiment Figure 1 .like Figure 1 As shown, the method for calculating carbon emissions during the whole life cycle of heavy metal contaminated site remediation provided in this embodiment includes:

[0069] S101. Determine a remediation technology combination corresponding to the contaminated site, and based on the remediation technology combination, determine a remediation process, wherein the remediation process includes: a plurality of links corresponding to the remediation technology combination.

[0070] Among them, the remediation technology refers to a series of methods used to remove or reduce the concentration of pollutants in the soil to restore the environmental quality of the land; the remediation technology combination refers to the combination of several single remediation technologies to give full play to their respective advantages and improve the remediation effect and efficiency.

[0071] The multiple links corresponding to the remediation technology combination refer to the different steps and stages involved in the implementation of contaminated site remediation. Each link has its specific functions and goals, which vary according to the remediation goals and the specific remediation technologies adopted.

[0072] For example, depending on the remediation technology, the links may include: earthwork, remediation and disposal projects, water body disposal projects, exhaust gas treatment projects, use of chemicals, use of materials, machinery, equipment, instruments, vehicles in measures projects, material production, chemical production, solid waste disposal and other carbon emission links in the whole process.

[0073] S102. During the restoration process of the polluted site, determining the man-made carbon emission information corresponding to each link and the natural carbon emission information corresponding to the restoration process.

[0074] Among them, the anthropogenic carbon emission information refers to the carbon emissions generated by energy consumption during the construction and transportation of mechanical equipment during the restoration of the contaminated site; the natural carbon emission information corresponding to the restoration process refers to the changes in soil organic carbon during the restoration of the contaminated site.

[0075] It can be understood that the man-made carbon emission information is determined based on the carbon emissions generated by the energy consumption of the equipment involved in each link during the implementation process; the natural carbon emission information corresponding to the remediation process is determined based on the carbon emissions caused by changes in the organic carbon content in the contaminated soil during the remediation process.

[0076] In a possible implementation, determining the man-made carbon emission information corresponding to each link and the natural carbon emission information corresponding to the restoration process may be achieved by the following method, including:

[0077] Human-caused carbon emission information: According to each link in the restoration technology combination, the equipment involved in each link is determined, and the carbon emissions generated by the energy consumed by the equipment involved during the implementation process are calculated based on relevant data.

[0078] Natural carbon emission information: Based on the combination of remediation technologies, the contaminated soil remediation batches are determined, and the changes in organic carbon content in the contaminated soil in different batches are calculated. The natural carbon emission information is determined based on the changes in organic carbon content in different batches of contaminated soil.

[0081] In this step, the carbon emission parameters corresponding to the restoration technology combination are calculated based on the man-made carbon emission information corresponding to each link and the natural carbon emission information.

[0082] In a possible implementation, determining the carbon emission parameters corresponding to the restoration technology combination may be achieved by the following method, including:

[0083] Determine the total anthropogenic carbon emission information of the polluted site according to the anthropogenic carbon emission information corresponding to the multiple links;

[0084] It can be understood that the total anthropogenic carbon emission information is a collection of anthropogenic carbon emission information corresponding to multiple links.

[0085] Determining the carbon emissions corresponding to the polluted site according to the total anthropogenic carbon emissions information and the natural carbon emissions information;

[0086] In this step, the carbon emissions corresponding to the polluted site are calculated by summing the total anthropogenic carbon emissions information and the natural carbon emissions information.

[0087] According to the carbon emissions corresponding to the multiple links, the carbon emission parameters corresponding to the restoration technology combination are determined.

[0088] The carbon emission parameters include: the amount of earthwork for repair, the carbon emissions of corresponding links and the corresponding unit carbon emissions.

[0089] The remediation earthwork volume refers to the volume of earth and stone that needs to be excavated, transported or processed during the remediation project, reflecting the scale of the soil remediation project and the degree of land treatment.

[0090] The carbon emissions of the corresponding links refer to the emissions of carbon dioxide or other greenhouse gases generated in each link during the soil remediation process, which is used to assess the impact of the remediation project on the environment.

[0091] The corresponding unit carbon emissions refer to the carbon emissions generated per unit earthwork volume or per unit restoration area, and can be used to compare the carbon emission levels of different restoration technologies.

[0092] In this step, the corresponding unit carbon emissions can be calculated by dividing the total carbon emissions by the corresponding earthwork volume or restoration area, wherein the total carbon emissions are the carbon emissions corresponding to the contaminated site.

[0093] This embodiment provides a method for calculating carbon emissions throughout the life cycle of heavy metal contaminated site remediation, which determines the remediation technology combination corresponding to the contaminated site, and based on the remediation technology combination, determines the remediation process, which includes: multiple links corresponding to the remediation technology combination; in the remediation process of the contaminated site, determines the man-made carbon emission information corresponding to each link and the natural carbon emission information corresponding to the remediation process; based on the man-made carbon emission information corresponding to each link and the natural carbon emission information, determines the carbon emission parameters corresponding to the remediation technology combination. This method combines and analyzes the man-made carbon emission information and natural carbon emission information in the remediation technology, thereby improving the accuracy of the carbon emission data of the remediation technology.

[0095] S201. For any one link among the multiple links, determine the mechanical carbon emissions corresponding to the mechanical energy consumption of multiple equipment in the link and the transportation carbon emissions corresponding to the transportation energy consumption.

[0096] Among them, the mechanical carbon emissions refer to the carbon dioxide emissions generated by multiple mechanical equipment in the link when consuming energy, which is calculated based on energy consumption and corresponding carbon emission factors.

[0098] The transportation carbon emissions refer to the carbon dioxide emissions generated by the energy consumed during the transportation process, and are also calculated based on the energy consumption and the corresponding carbon emission factors.

[0099] In this step, the multiple links include earthwork, restoration and disposal, water body disposal, exhaust gas treatment, use of chemicals, use of materials, and measures engineering.
