Description

Technical Field

[0001] The present application relates to the technical field of waste disposal, and in particular to a carbon emission analysis system for landfills. Background Art

[0002] With the rapid development of society and the increasing affluence of people's material lives, the amount of waste generated per capita is also increasing year by year. Landfill is currently one of the primary methods of domestic waste disposal. After landfill disposal, as the waste decays and ferments, large amounts of greenhouse gases are gradually released into the atmosphere. When greenhouse gas emissions are measured, statistical calculations are often performed to derive carbon emissions from landfills.

[0003] In the carbon emission calculation method for landfill projects in related technologies, the calculation data related to the composition and chemical elements of the garbage are based on empirical data. At the same time, due to the high cost and long monitoring cycle, there is currently no clear carbon emission monitoring method for landfills, so the deviation between actual emissions and calculated emissions is difficult to determine.

[0004] Therefore, improvements are needed to address at least one of the above problems. Summary of the Invention

[0009] Illustratively, the incoming garbage information includes historical landfill statistics, historical garbage physical composition, organic carbon content of different types of garbage, and methane generation rate of different types of garbage.

[0010] For example, the calculation module calculates the carbon emissions of the landfill site using the calculation factor and the incoming garbage information, and obtains the carbon emissions using the following formula:

[0011]

[0013] Exemplarily, the organized emission pipeline monitoring includes: monitoring the gas concentration, gas flow rate, temperature and pressure in the pipeline; calculating the product of the gas concentration, the ratio of the standard state temperature to the actual temperature, the ratio of the actual pressure to the standard state pressure, and the gas flow rate as the carbon emission flux; calculating the integral of the product of the carbon emission flux and the pipeline cross-sectional area over time t as the carbon emissions.

[0015] Exemplarily, the constant value is 1.

[0016] Exemplarily, the analysis module analyzes and compares the monitoring results and the accounting results, including: comparing the carbon emissions of different emission sources in the monitoring results to obtain the main sources of greenhouse gas emissions; comparing the differences in the carbon emissions under different environmental factors in the monitoring results to confirm the deviations caused by the environmental factors; and comparing the accounting results to obtain the impact of different materials in the landfill on the accounting results.

[0029] Please refer to Figure 1-Figure 3 , a carbon emission analysis system based on landfill is provided in an embodiment of the present application.

[0030] The method includes a monitoring module, a calculation module, and an analysis module. The monitoring module is used to monitor carbon emissions from different emission sources and obtain monitoring results. The calculation module calculates carbon emissions from landfill sites using calculation factors and incoming waste information to obtain calculation results, where the calculation factors are empirical parameters input during the calculation process. The analysis module is used to analyze and compare the monitoring results with the calculation results and to modify the calculation factors of the calculation module.

[0031] The monitoring results and the accounting results are obtained through the monitoring module and the accounting module, and then the obtained results are analyzed and compared through the analysis module, and the accounting factors of the accounting module are corrected to improve the accounting module.

[0032] Please refer to Figure 1 The monitoring module is used to monitor carbon emissions from different emission sources. In this application, the monitoring module includes four parts: organized emission pipeline monitoring, unorganized emission surface source monitoring in landfill areas, leachate / wastewater disposal emission monitoring, and other emission point monitoring.

[0033] For organized emission pipeline monitoring, the primary approach is to calculate the carbon emission flux by monitoring the gas concentration, flow rate, temperature, and pressure in the biogas combustion exhaust pipe and biogas flare burner pipeline. This is then combined with the operating time and pipeline area to calculate the carbon emissions over the operating cycle. For example, the monitoring and calculation are performed using the following method.

[0034] First, the gas concentration, gas flow rate, temperature, and pressure in the pipeline are detected. Then, the carbon emission flux is calculated by multiplying the gas concentration, the ratio of the standard temperature to the actual temperature, the ratio of the actual pressure to the standard pressure, and the gas flow rate. Finally, the carbon emission flux is calculated by multiplying the product of the carbon emission flux and the cross-sectional area of the pipeline over time t. Specifically, it can be calculated using the following formula:

[0035]

[0036] M=∫Q·Sdt

[0037] In the above formula, Q is the carbon emission flux; C is the gas concentration; T0 is the standard state temperature; T is the actual temperature; P0 is the standard state pressure; P is the actual pressure; ν is the gas flow rate; M is the carbon emission (mass); S is the pipeline cross-sectional area; and t is time.

[0038] First, the carbon emission flux is obtained by obtaining various data in the pipeline, and then the carbon emissions within the operating cycle are calculated together with the operating time and pipeline area. In this way, the carbon emissions of the organized emission pipeline within the specified operating cycle are obtained.

[0039] For landfill area fugitive emission source monitoring, the greenhouse gas emissions emitted from the landfill surface are monitored using a static trough measurement method. Specifically, it is necessary to rationally distribute points within the landfill area and use closed static troughs to collect greenhouse gases emitted per unit area of the landfill during a specified operating cycle. The average carbon emissions of the gases in the static troughs at all the distribution points are then used as the carbon emissions per unit area of the landfill during the specified operating cycle. The greenhouse gas emissions from the fugitive emission sources in the entire landfill area are then calculated in sequence.

[0040] For example, the monitoring of non-point sources of unorganized emissions in landfill areas is achieved by the following methods:

[0041] First, static tanks are deployed throughout the landfill area to collect greenhouse gases emitted per unit area of the landfill over a specified period. Next, the carbon emissions from the static tanks are calculated by multiplying the greenhouse gas concentration within the static tanks, the ratio of the standard temperature to the actual temperature, the ratio of the actual pressure to the standard pressure, and the volume of the static tanks. Finally, the carbon emissions from the landfill are calculated by multiplying the sum of the carbon emissions from the static tanks for different numbers of static tanks, the ratio of the landfill area to the static tank collection area, and the constant value by the ratio of the number of static tanks, where the constant is 1.

[0042] For example, the greenhouse gas emissions from unorganized emission sources in the entire landfill area are calculated using the following formula:

[0043]

[0044]

[0045] Where m is the static tank carbon emissions; M is the landfill area carbon emissions; C is the static tank greenhouse gas concentration; V is the static tank volume; T0 is the standard temperature; T is the actual temperature; P0 is the standard pressure; P is the actual pressure; S is the landfill area; S0 is the static tank collection area; and n is the number of static tank locations. When monitoring and calculating greenhouse gas emissions from fugitive non-point sources in landfill areas, first calculate the static tank carbon emissions, then the landfill area carbon emissions.

[0046] Leachate / wastewater disposal emission monitoring refers to the monitoring of greenhouse gas emissions generated during the disposal of leachate / wastewater generated in landfill projects, which includes the monitoring of emission sources such as leachate A / O pools, leachate storage tanks and leachate treatment workshops. The monitoring methods are divided into organized emission pipeline monitoring and unorganized emission surface source monitoring. These two monitoring methods are the same as the above-mentioned organized emission pipeline monitoring and unorganized emission surface source monitoring methods, and will not be repeated here.

[0047] Other emission point monitoring refers to the monitoring of carbon emissions from other forms of greenhouse gas emission facilities, in addition to the three main emission sources mentioned above. It should be noted that in this application, when monitoring and calculating greenhouse gases, the greenhouse gas mainly targeted is methane, and the carbon emission results are obtained by monitoring the carbon emissions of methane gas.

[0048] Please follow Figure 2, for the accounting module, it refers to the calculation of greenhouse gas emissions from landfills using specific methods based on the actual physical composition and chemical element composition of landfilled garbage. The parameters required for the accounting process mainly include accounting factors and information on incoming garbage. Among them, accounting factors are empirical parameters that need to be input during the accounting process. Since the greenhouse gases generated by landfills mainly come from methane emissions, the accounting factors that need to be input include methane correction factors, methane fractions, global warming potential of methane, oxidation coefficients, volume fractions of methane in landfill gas, the proportion of degradable organic carbon under specific conditions in landfills after a specified year, methane generation rates of different types of garbage, and methane conversion factors. For example, the specified year is year y. When performing accounting, x is used to represent the accounting period, which means from year 1 to year y.

[0049] Incoming waste information is calculated based on actual landfill waste, obtained through statistics, physical sorting, and chemical testing. This information includes historical landfill statistics, the physical composition of waste, the organic carbon content of different types of waste, and the methane generation rate of different types of waste. Historical landfill statistics are based on project operational data, while the physical composition of waste and the organic carbon content of different types of waste are obtained through laboratory sampling, classification, and testing.

[0050] The accounting module calculates the carbon emissions of the landfill site using the accounting factors and the incoming garbage information. For example, it is calculated using the following formula.

[0051]

[0052] Among them, φ y is the methane correction factor; f y Fraction of methane collected for landfill, combustion, ignition, or other means; GWP CH4 is the global warming potential of methane; OX is the oxidation coefficient; F is the volume fraction of methane in landfill gas; DOCf,y is the proportion of degradable organic carbon under specific conditions of the landfill in year y; MCF is the conversion factor of methane; W j,x is the amount of organic waste of type j disposed in landfill in year x; DOC j is the fraction of degradable organic carbon in solid waste type j; kj is the decay rate of waste type j; j is the waste type; x is the accounting period, representing the period from year 1 to year y; y is the year of methane emissions calculation; and e is a natural constant. Through this method, the accounting module calculates carbon emissions from landfills. The accounting process is similar to that of the monitoring module, with the primary focus on methane emissions.

[0053] Please refer to Figure 3 ,For the analysis module, it is used to compare the total greenhouse gas emissions obtained by the ,monitoring module and the accounting module, analyze the difference in the total emissions ,of the two statistical methods, and further improve the statistical methods of the ,two modules through difference analysis.

[0054] The work of the analysis module includes four aspects:

[0055] First, the analysis module analyzes the main sources of greenhouse gas emissions. During the operation of the monitoring module, the greenhouse gas emissions of different emission sources can be obtained. By comparing the greenhouse gas emissions of different emission sources in the monitoring module, the main sources of greenhouse gas emissions can be determined.

[0056] The monitoring module calculates greenhouse gas emissions from landfill methane combustion stacks, burner pipes, landfill surface emissions, leachate / wastewater disposal, and other emission points. By comparing the proportion of greenhouse gas emissions from different sources to total emissions, we can determine the source distribution of greenhouse gas emissions.

[0057] Secondly, the analysis module is used to analyze the impact of different factors on emission results during the monitoring process, that is, to analyze the differences in greenhouse gas emissions under different temperatures, pressures, and flow rates, and further reduce or eliminate the deviation of statistical results caused by uncontrollable factors.

[0058] From the emission formulas of organized pipelines and unorganized surface sources, it can be seen that the statistical value of greenhouse gas emissions is mass statistics. However, in the actual measurement process, only the gas concentration can be measured, and the standard state gas content (kg / Nm 3 ), so during the conversion process it is necessary to monitor gas flow rate, temperature, pressure and other parameters to convert and correct the gas concentration, and ultimately determine the actual greenhouse gas emissions.

[0059] For example, under the same pressure and flow rate, greenhouse gas emissions at different temperatures are calculated, and the impact of temperature on greenhouse gas emission calculations is analyzed. This means that through formulas and statistical data, a linear coefficient or functional relationship for the impact of temperature on greenhouse gas emissions can be derived. Further analysis can be conducted on the impact of other factors, such as pressure and flow rate, to determine the impact of different factors on greenhouse gas emission statistics and the extent of their impact. Therefore, if adverse conditions significantly impact the statistical results during the statistical period, such as damage to temperature or pressure sensors or extremely severe weather, the results of the analysis of previous impacts can be used to correct the statistics of greenhouse gas emissions under these adverse conditions and reduce statistical bias.

[0060] Thirdly, the analysis module analyzes the impact of incoming waste information on the accounting results, that is, by comparing the impact of material composition and chemical element composition on the accounting results, it further improves the acquisition and processing methods of information data to improve the accuracy and representativeness of the accounting; for example, through the accounting formula, it can be seen that the greenhouse gas emissions of landfills are related to the composition of waste and the chemical elements of different components (DOC j ) is directly related. The accounting formula can be used to determine the impact of different component proportions on greenhouse gas emissions (i.e., the linear coefficient of the impact of component composition or organic carbon composition on emissions accounting can be obtained through the formula). For example, when the plastic content of landfill waste is high, since plastic does not contain organic carbon, there will be no greenhouse gas emissions during the landfill of plastic waste. Conversely, when the food or plant content of landfill waste is high, the amount of greenhouse gas emissions during the landfill process is relatively large due to the high organic carbon content of food and plant components.

[0061] Therefore, by calculating the impact of different garbage compositions on greenhouse gas emission accounting results, we can obtain the degree of influence of garbage sampling representativeness and uniformity on the accounting, and further improve the sampling approach and detection method of garbage composition detection.

[0062] Fourthly, the analysis module corrects the accounting factors, that is, by comparing the total amount of greenhouse gas emissions from two different methods of monitoring and accounting, the accounting factors applied in some accounting processes are corrected to make them closer to the current actual situation.

[0063] Monitoring and accounting are two different methods for calculating greenhouse gas emissions. Accounting results will inevitably deviate to some extent from actual monitoring results. When a discrepancy arises between monitoring and accounting results, a comparison of accounting and testing can identify at least one accounting factor that requires correction and allow for adjustments to be made.

[0064] For example, by testing the composition of landfill waste, the degradable organic carbon in different waste components is tested and analyzed, and the empirical value is corrected using the actual test value; by comparing the annual statistics of multiple greenhouse gas emission monitoring values and accounting values, the proportion of degradable organic carbon (DOC f,y ) is corrected; by monitoring the other components and contents of different greenhouse gases in the landfill gas, the volume fraction of methane (F) in the landfill gas is corrected.

[0065] Through the above technical solution, the present application provides a landfill-based carbon emission analysis system that obtains actual monitoring results through the monitoring module and obtains accounting results through the accounting module and accounting factors. The accounting results are empirical values obtained based on previous statistical experience. When the accounting results differ from the monitoring results, the accounting factors can be corrected through analysis and comparison to make the results more accurate. This improves the accounting model.
