[0013] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.
[0014] In order to make the above-mentioned objects, features and advantages of the present application more obvious and easy to understand, the present application is further described in detail below with reference to the accompanying drawings and specific implementation methods.
[0015] In an exemplary embodiment, Figure 1 As shown, a method for evaluating the pollution reduction and carbon reduction pathway in the kitchen waste treatment process is provided, comprising the following steps 101 to 106. Among them:
[0016] Step 101: Determine the boundary scope of the food waste treatment process of the project to be evaluated.
[0017] Step 102: Determine the total greenhouse gas emissions and emissions of each pollutant in the food waste treatment process within the boundary.
[0018] Step 103: Construct a pollution reduction and carbon reduction synergistic control effect evaluation model.
[0019] Step 104: Based on the total greenhouse gas emissions and the emissions of each pollutant, the pollution reduction and carbon reduction synergistic control effect assessment model is used to obtain the pollution reduction and carbon reduction score of the project to be assessed.
[0020] Step 105: If the pollution reduction and carbon reduction score of the project to be evaluated is greater than or equal to the preset score threshold, it is determined that the pollution reduction and carbon reduction path of the project to be evaluated meets the pollution reduction and carbon reduction standards.
[0021] Step 106: If the pollution reduction and carbon reduction score of the project to be evaluated is less than the preset score threshold, it is determined that the pollution reduction and carbon reduction path of the project to be evaluated does not meet the pollution reduction and carbon reduction standards.
[0022] Implement the above steps 101 to 106, consider the boundary range of the food waste treatment process, and establish a pollution reduction and carbon reduction synergistic control effect evaluation model to score the pollution reduction and carbon reduction path of the project to be evaluated, and determine whether the pollution reduction and carbon reduction path of the project to be evaluated meets the pollution reduction and carbon reduction standards, so that based on the determination result, pollution reduction and carbon reduction in the food waste treatment process can be effectively promoted.
[0023] In another exemplary embodiment of the present application, the above step 101 may be replaced by the following steps 201 to 202:
[0024] Step 201: Determine the food waste treatment process of the project to be evaluated; the food waste treatment process includes: food waste collection, food waste transportation and food waste disposal.
[0025] By searching for information and conducting field research, the project's kitchen waste treatment process was determined, including: aerobic composting, anaerobic fermentation, landfill, pyrolysis incineration, and feed production.
[0026] Step 202: compile a boundary range map based on the food waste treatment process, and obtain the boundary range of the food waste treatment process of the project to be evaluated from the boundary range map.
[0027] The boundary range of the food waste treatment process is as follows: Figure 2 shown.
[0028] In another exemplary embodiment of the present application, the above step 102 may be replaced by the following steps 301 to 304:
[0029] Step 301: Verify the greenhouse gas emission sources and pollution emission sources of the food waste treatment process within the boundary range, and compile a greenhouse gas emission source list and a pollution emission source list.
[0030] The greenhouse gas emission source list and the pollution emission source list include the types of emission sources, emission devices, facilities or activities, emission media used, types of greenhouse gases produced, and types of pollutants, as shown in Table 1.
[0031] Table 1 Greenhouse gas emission source list and pollution emission source list
[0032]
[0033]
[0034] Step 302: Establish a greenhouse gas emission accounting model based on the greenhouse gas emission source inventory.
[0035] Step 303: According to the greenhouse gas emissions actually generated by the project to be evaluated at each stage of the kitchen waste treatment process, the total greenhouse gas emissions of the kitchen waste treatment process within the boundary range are obtained using the greenhouse gas emission accounting model.
[0036] Step 304: Based on the pollution emission source list, obtain the emission amount of each pollutant in the food waste treatment process of the project to be evaluated.
[0037] In another exemplary embodiment of the present application, the greenhouse gas emission accounting model established according to the emission device facilities or activities is:
[0038] EGHG 排放 =E 厨余垃圾投放点 +E 厨余垃圾桶站 +E 运输过程 +E 厨余处置点 +E 产品 ;
[0039] Where, EGHG 排放 is the total greenhouse gas emissions from the food waste disposal process, E 厨余垃圾投放点 is the greenhouse gas emissions generated at the food waste disposal point, E 厨余垃圾桶站 is the greenhouse gas emissions generated at the food waste bin station, E 运输过程 is the greenhouse gas emissions generated during the transportation of food waste, E 厨余处置点 is the greenhouse gas emissions generated at the food waste disposal site, E 产品 The amount of carbon reduction generated during the kitchen waste disposal process.
[0040] In another exemplary embodiment of the present application, the greenhouse gas emission accounting model established according to the emission device facilities or activities is:
[0041] EGHG 排放 =E 固定燃烧 +E 工艺 / 过程排放 +E 移动燃烧 +E产品 ;
[0042] Where, EGHG 排放 represents the total greenhouse gas emissions from the food waste disposal process, E 固定燃烧 represents greenhouse gas emissions from stationary combustion, E 工艺 / 过程排放 Indicates the greenhouse gas emissions from a process or procedure, E 移动燃烧 represents the greenhouse gas emissions generated by vehicle movement, E 产品 Indicates the amount of carbon reduction generated during the food waste disposal process.
[0043] The data on the right side of the greenhouse gas emission accounting model equation can be obtained by referring to existing standards and specifications to calculate each greenhouse gas emission source, or directly measuring greenhouse gas emissions or pollutant emissions data.
[0044] In another exemplary embodiment of the present application, the total pollutant emission in the process of kitchen waste treatment is calculated as follows:
[0045] EP 排放 ={EP 固废 ,EP 废水、 EP 废气};
[0046] Where, EP 排放 is the total amount of pollutant emissions, EP 固废 is the solid waste discharge, EP 废水 is the wastewater discharge, EP 废气 The exhaust gas emission.
[0047] In another exemplary embodiment of the present application, the above step 103 may be replaced by the following steps 401 to 404:
[0048] Step 401: Establish a pollution reduction and carbon reduction assessment index system for the kitchen waste treatment process; the pollution reduction and carbon reduction assessment index system includes primary indicators, secondary indicators and tertiary indicators, and the primary indicators of the pollution reduction and carbon reduction assessment index system include at least pollution reduction amount and carbon reduction amount.
[0049] Different evaluation indicators can be introduced into the pollution reduction and carbon reduction assessment index system according to the factors and treatment methods that need to be considered for projects in different periods.
[0050] Step 402: Assign a weight to each primary indicator.
[0051] The weights need to be obtained by inviting experts to score to ensure that the weights are objective and fair. The weights can also be limited according to policy requirements in different periods. The weight distribution is shown in Table 2.
[0052] B1+B2+B3+……Bn =1;
[0053] Table 2 Weight distribution
[0054] factor Pollution reduction Carbon reduction Economic costs …… total Weight <![CDATA[B1]]> <![CDATA[B2]]> <![CDATA[B3]]> <![CDATA[B n ]]> 1
[0055] Step 403: Set the pollution reduction and carbon reduction effect scoring standards for the three-level indicators.
[0056] Step 404: Establish a calculation formula for pollution reduction and carbon reduction score: Where T is the pollution reduction and carbon reduction score, B i is the weight of the first-level index i, C i is the score of the first-level indicator i determined by the three-level indicators, and n is the number of first-level indicators.
[0057] In another exemplary embodiment of the present application, when the primary indicator of the pollution reduction and carbon reduction assessment index system includes pollution reduction amount, carbon reduction amount and economic cost:
[0058] The secondary indicators corresponding to pollution reduction include solid waste, waste gas and wastewater; the tertiary indicators corresponding to solid waste include sludge and residue; the tertiary indicators corresponding to waste gas include carbon monoxide, hydrocarbons, nitrogen oxides, particulate matter and sulfur oxides; the tertiary indicators corresponding to wastewater include leachate, garbage filtrate and sludge.
[0059] The secondary indicators corresponding to carbon reduction include greenhouse gas emissions; the tertiary indicators corresponding to greenhouse gas emissions include direct emissions, indirect emissions and carbon reduction emissions; among them, the sum of the direct greenhouse gas emissions and the indirect greenhouse gas emissions is equal to the total greenhouse gas emissions, and the greenhouse gas emissions of carbon reduction emissions are equal to the total greenhouse gas emissions minus the average greenhouse gas production of existing known technologies.
[0060] The secondary indicators corresponding to economic costs include cost input and operating expenses; the tertiary indicators corresponding to cost input include the purchase of equipment for project construction collection points, barrel stations and disposal points; the tertiary indicators corresponding to operating expenses include project electricity, personnel expenses and transportation.
[0061] The pollution reduction and carbon reduction assessment indicator system is shown in Table 3.
[0062] Table 3 Pollution reduction and carbon reduction assessment indicator system
[0063]
[0064] In another exemplary embodiment of the present application, the pollution reduction and carbon reduction effect scoring criteria include: if it is equal to the average value of the existing known technology, then 6 points; for every 10% higher than the average value of the existing known technology, 1 point is deducted; for every 10% lower than the average value of the existing known technology, 1 point is added; wherein the average value of the existing known technology is the average value of the pollutant generation of the existing known technology, the average value of the greenhouse gas generation of the existing known technology, or the average value of the existing known cost. The pollution reduction and carbon reduction effect scoring criteria are shown in Table 4.
[0065] Table 4 Scoring criteria for pollution reduction and carbon reduction effects
[0066]
[0067] C1=D1+D2+D3, C2=D4+D5+D6,….
[0068] When determining the total score D1 of sludge, residues, etc., the average amount of pollutants generated by existing known technologies should be the average amount of pollutants generated by sludge, residues, etc.; when determining the total score D2 of carbon monoxide, hydrocarbons, nitrogen oxides, particulate matter, sulfur oxides, etc., the average amount of pollutants generated by existing known technologies should be the average amount of carbon monoxide, hydrocarbons, nitrogen oxides, particulate matter, sulfur oxides, etc.; and so on.
[0069] The existing known technologies for each indicator are published data, so the scoring criteria can be dynamically updated based on policies and existing technologies.
[0070] In another exemplary embodiment of the present application, the above step 104 may be replaced by the following steps 501 to 503:
[0071] Step 501: According to the emission amount of each pollutant in the kitchen waste treatment process within the boundary range, based on the pollution reduction and carbon reduction effect scoring standard of the three-level indicators, determine the score of the three-level indicator corresponding to the pollution reduction amount.
[0072] Step 502: Determine the score of the third-level indicator corresponding to the carbon reduction amount according to the total greenhouse gas emissions and the pollution reduction and carbon reduction effect scoring standard of the third-level indicator.
[0073] The total greenhouse gas emissions minus the average total greenhouse gas production of existing known technologies can be used to obtain the carbon reduction emissions in Table 4, and then D6 can be obtained.
[0074] Step 503: According to the scores of the third-level indicators corresponding to the pollution reduction amount, the scores of the third-level indicators corresponding to the carbon reduction amount and the weight of each first-level indicator, the pollution reduction and carbon reduction score calculation formula is used to obtain the pollution reduction and carbon reduction score of the project to be evaluated.
[0075] This application is based on the main types of kitchen waste disposal and the latest requirements for kitchen waste disposal. It takes into account the classification and collection of kitchen waste, on-site backfilling, transportation and treatment (resource processing, landfilling) processes and greenhouse gas emissions, and constructs a model system for evaluating the pollution reduction and carbon reduction capabilities of the kitchen waste treatment process. It effectively promotes the construction of a methodological system for greenhouse gas emission reduction in the kitchen waste treatment process and promotes greenhouse gas emission reduction in the kitchen waste field.
[0076] Based on the same inventive concept, in an exemplary embodiment, Figure 3 As shown, the embodiment of the present application also provides a method for optimizing the pollution reduction and carbon reduction path in the kitchen waste treatment process, including the following steps 601 to 603.
[0077] Step 601: Determine the pollution reduction and carbon reduction pathways for the project to be evaluated under different factor scenarios for food waste treatment.
[0078] Step 602: Based on the food waste treatment process of the project to be evaluated under each factor scenario, the pollution reduction and carbon reduction score of the project to be evaluated under each factor scenario is obtained using the above-mentioned food waste treatment process pollution reduction and carbon reduction path assessment method.
[0079] Step 603: Select the pollution reduction and carbon reduction path corresponding to the factor scenario with the highest pollution reduction and carbon reduction score as the optimal pollution reduction and carbon reduction path.
