[0175] In this embodiment, the environmental protection treatment equipment is systematically and comprehensively sorted out and checked, and all carbon emission sources, types and activity data are collected, studied and identified in the carbon emission scenarios of the environmental protection treatment equipment during the entire life cycle of the production and manufacturing stage, transportation stage, operation and use stage, and scrapping and demolition stage, and the direct carbon emissions, indirect carbon emissions and negative carbon of the environmental protection treatment equipment are evaluated. According to the determined carbon emission influencing factors, their impact on the actual carbon emissions is examined, and the carbon accounting method of environmental protection treatment equipment is established, improved and unified in a targeted manner, which is more conducive to improving the accuracy of carbon accounting in projects such as waste gas treatment, sewage treatment or sludge treatment.

[0176] Furthermore, this embodiment not only comprehensively sorts out and simplifies the carbon accounting method for environmental protection treatment equipment, but also clarifies the specific details in the method, and clarifies that the negative carbon amount of environmental protection treatment equipment does not include natural carbon sinks. The negative carbon amount in the production, operation, use, and scrapping and demolition stages includes the carbon compensation generated by the use of clean energy or additional output energy, and the carbon capture of carbon capture and storage technology (CCS) or carbon capture, utilization and storage (CCUS) technology. In addition, the negative carbon amount in the scrapping and demolition stage also includes the carbon offset generated by the recycling of material / equipment resources.

[0177] In addition, based on the carbon emission activity data of environmental protection treatment equipment in this embodiment, it is helpful to establish a carbon emission database, clarify the carbon emission laws and mechanisms of environmental protection treatment equipment, focus on exploring the carbon emission reduction potential of each carbon emission point, and start from low-carbon transformation technologies such as energy saving, material saving, and land saving. It can form an energy-saving and low-carbon transformation technology route to promote the low-carbon and efficient development of the environmental protection equipment manufacturing industry.

[0178] For example, in this embodiment, by evaluating the carbon accounting of sludge drying and environmental protection treatment equipment, it can be clarified that low-temperature drying meets the strategic needs of low-carbon development of urban sludge, and can effectively alleviate the problems of difficult sludge dehydration, high energy consumption, large carbon emissions and limited land use. By evaluating and discussing the energy-saving and emission-reduction, green and low-carbon technologies and paths of sludge drying and environmental protection treatment equipment in different application scenarios, the best sludge treatment and disposal combined route can be clarified. During the operation and use of low-temperature sludge drying equipment, coupled with energy-saving heating technologies such as cogeneration and recycled water waste heat recovery, heat energy is output to the outside to form carbon compensation for the equipment's carbon accounting. Low-temperature drying has low carbon emissions and high pollution reduction rates for coordinated incineration / carbonization, which is suitable for terminal scenarios such as carbon-based fuel utilization, garden utilization and building materials utilization.

[0179] For another example, in this embodiment, taking a certain sulfur autotrophic filler as an example during the operation and use stage of the sewage denitrification equipment, according to the materials, energy consumption and corresponding carbon emission factors required for preparing a unit weight of carrier filler, the carbon emission accounting results of the preparation and production of unit carrier filler are calculated as shown in Tables 9 to 11:

[0180] Table 9 Materials and electricity consumption required for preparing unit weight of carrier filler

[0181]

[0182] Table 10 Carbon emission factors per unit of material and electricity consumption

[0183]

[0184] Table 11 Carbon emission calculation results of production per unit weight of carrier filler

[0185]

[0186] The carbon emission generated by each ton of autotrophic denitrification carrier filler is calculated to be 1.88 t CO2, which is higher than the carbon emission generated by producing each ton of sodium acetate in the heterotrophic denitrification method (0.623 t CO2, as can be seen from the carbon emission factor database of my country). However, the carbon emission generated by the unit amount of TN in the operation and use stage of the sewage denitrification equipment using autotrophic denitrification carrier filler for autotrophic denitrification (5.6 t CO2 / t TN) is lower than the carbon emission of heterotrophic denitrification using sodium acetate (6.96 tCO2 / t TN). In summary, although the production carbon emission factor of autotrophic denitrification carrier filler is higher than that of the agent sodium acetate used in heterotrophic denitrification equipment, the total carbon emission intensity of sewage autotrophic denitrification equipment is lower than that of sewage heterotrophic denitrification equipment, especially with the extension of operation and use time, the carbon saving effect is more obvious. Therefore, it is more low-carbon for sewage denitrification equipment to adopt autotrophic mode for a long time.

[0187] Taking the aforementioned sulfur autotrophic filler as an example, the carbon emissions during its manufacturing stage are verified. The specific process is as follows:

[0188] The dynamic chamber method was used for gaseous greenhouse gases, and the headspace balance method was used for dissolved greenhouse gases. The greenhouse gas monitoring and analysis of the denitrification environmental protection equipment showed that the emission factors of CH4 and N2O in the anoxic / aerobic-denitrification filter combination process were 0.0003% and 0.022%, respectively, which were lower than the default values ​​recommended by the IPCC (the emission factor of CH4 was 5%-10%, and the emission factor of N2O was 0.5%). The direct emission of CH4 and N2O from the low-carbon autotrophic deep denitrification filter was low, and the emission flux of CH4 was 0.003 mg·m -2 ·h -1 , the emission factor is 0.0000113%; the N2O emission flux is 0.01 mg·m -2 ·h -1 , the emission factor is 0.000156%, which is consistent with the conclusion that the heterotrophic mode has a lower carbon characteristic than the aforementioned autotrophic denitrification operation mode.

[0192] A quantitative statistics module, which is used to sort out and identify all carbon emission sources in each stage of the life cycle, and to quantify and count the direct greenhouse gas emission data, energy consumption and resource usage involved in each of the carbon emission sources in each stage, and to call the global warming potential value that matches the direct greenhouse gas emission data, and the carbon emission factor that matches the energy consumption and resource usage;

[0193] A model building and calculation module, the model building and calculation module is used to build a carbon footprint calculation model, and import the greenhouse gas direct emission data and the matching global warming potential value, the energy consumption and the resource usage and the matching carbon emission factor into the carbon footprint calculation model for calculation, to obtain the stage carbon emissions and the total carbon emissions of each stage in the life cycle; the total carbon emissions is the sum of the stage carbon emissions of each stage;

[0194] A verification and storage module, the verification and storage module is used to verify the carbon emissions of the stage or the total carbon emissions, and store them in a document of a preset format after verification; wherein the content of the document includes the structured composition of the environmental protection treatment equipment, the carbon accounting boundary, the carbon emission source, the direct greenhouse gas emission data and the matching global warming potential value, the energy consumption and the resource usage and the matching carbon emission factor, the carbon footprint calculation model, the stage carbon emissions of each stage in the life cycle, and the total carbon emissions.

[0195] Example 3

[0196] This embodiment provides an application method of the carbon accounting method for environmental protection treatment equipment. After the initial structural composition design of the environmental protection treatment equipment and its initial model / parameter selection are completed, the carbon accounting method for environmental protection treatment equipment in the aforementioned embodiment 1 is used to estimate the total carbon emissions of the initially designed environmental protection treatment equipment, and then the structural composition of the environmental protection treatment equipment is confirmed or revised based on the estimated total carbon emissions.

[0197] For example, if the estimated total carbon emissions meet the current carbon emissions control requirements, the design is qualified. For another example, if the estimated total carbon emissions exceed the current carbon emissions control requirements, the structural composition is revised on the premise of meeting the functional requirements, the equipment raw materials or non-equipment raw materials are replaced, and then the total carbon emissions are re-estimated until the estimated total carbon emissions meet the current carbon emissions control requirements. Among them, the energy consumption and resource usage in the estimation process can be adopted according to the average value of the corresponding daily actual statistical data.

[0198] For example, in this embodiment, the total carbon emissions of the initially designed sewage denitrification equipment are estimated, and the structural composition of the sewage denitrification equipment is confirmed or modified accordingly, so that the final sewage denitrification equipment can not only meet the functional requirements but also meet the carbon emission requirements.
