[0037] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0039] Fossil carbon emissions are calculated by calculating the consumption of fossil fuels and obtaining fossil carbon emissions through a fixed conversion formula;

[0040] ,

[0041] in, The carbon conversion factor of fossil fuels is expressed in , It represents the mass of fossil fuel consumed, in L. Indicates carbon emissions.

[0042] Gas carbon emission calculation, in the present embodiment, the gas carbon content in the organic fertilizer fermentation process is calculated by sampling calculation and later correction. In the calculation of gas carbon content in the organic fertilizer fermentation process, a sample organic fertilizer per unit mass is extracted by sampling, and the carbon dioxide and hydrogen sulfide mass produced by the sample fermentation under the closed container are calculated, and then the ATP content of the sample organic fertilizer and the sampling source organic fertilizer is calculated by ATP bioluminescence method, and a relationship equation between the two is constructed, and finally the total carbon emission of the sampling source organic fertilizer is solved; after obtaining the total carbon emission of the unit sampling source organic fertilizer, the carbon emission produced by the organic fertilizer fermentation process can be calculated according to the total mass of the organic fertilizer to be fermented.

[0043] Electricity carbon emission calculation: The electricity carbon emission calculation module counts the electricity consumed in each link of crushing and mixing, ventilation control, and temperature control. The carbon emissions generated by electricity consumption can be calculated through the existing electricity-carbon conversion method;

[0044] Comprehensive carbon emissions calculation, the carbon emissions obtained by fossil carbon emissions calculation, gas carbon emissions calculation and electricity carbon emissions calculation are added together to obtain the comprehensive carbon emissions of the organic fertilizer production process.

[0045] Embodiment 2, as Figure 2 and Figure 3As shown, a carbon emission weight calculation system for an organic fertilizer production process includes a fossil carbon emission calculation module, a gas carbon emission calculation module, an electric power carbon emission calculation module and a comprehensive carbon emission calculation module;

[0046] The fossil carbon emission calculation module is used to calculate the carbon emission in the transportation link by calculating the consumption of fossil fuels and performing carbon emission calculation through a fixed conversion formula;

[0047] The gas carbon emission calculation module is responsible for calculating the carbon content in the gas produced by microbial fermentation during the organic fertilizer fermentation process, and calculates the carbon content of the gas during the organic fertilizer fermentation process by sampling calculation and post-correction;

[0048] The electric power carbon emission calculation module counts the electric energy consumed in each link of crushing and mixing, ventilation control and temperature control, and obtains the carbon emission generated by electricity through the electric-carbon conversion method;

[0049] The comprehensive carbon emission calculation module obtains the comprehensive carbon emission of the organic fertilizer production process according to the calculation results of the fossil carbon emission calculation module, the gas carbon emission calculation module and the electric power carbon emission calculation module.

[0050] Among them, the gas carbon emission calculation module includes a sampling calculation module and a correction module; the sampling calculation module calculates the mass of carbon dioxide and hydrogen sulfide produced by sample fermentation in a closed container by sampling; the correction module corrects the carbon emission mass of the sampling calculation module.

[0051] Embodiment 3, as Figure 4 As shown, the calculation of gas carbon emissions is a field that is rarely involved in existing methods. The present invention uses sampling calculation and post-correction to calculate the gas carbon content in the organic fertilizer fermentation process. The specific steps are as follows:

[0052] Step 1: extracting a unit mass of sample organic fertilizer from the organic fertilizer that has been composted and is ready for fermentation. The extraction method is intermittent extraction, which is performed multiple times to reach the unit mass. The unit mass taken in the embodiment of the present invention is 1 kg, which is completed in 10 times, that is, 0.1 kg is extracted each time.

[0053] Step 2: Place the sampled organic fertilizer in a sealed container, wherein the sealed container comprises a sample holding sub-container and a calcium hydroxide solution holding sub-container connected at the top by a pipe, wherein the sample holding sub-container is provided with an air injection port, and the calcium hydroxide solution holding sub-container is provided with an air outlet, and has an air injection port and an air outlet, such as Figure 3 As shown;

[0054] Step 3: Place the sealed container in the same environment as the sampling source for fermentation. It will flow through the pipe into a container containing calcium hydroxide solution. A chemical reaction occurs to form a precipitate:

[0055] ,

[0056] In addition, the small amount of fermentation produced Will also Reacts to form calcium sulfide :

[0057] ,

[0058] Step 4: When the fermentation is finished, introduce nitrogen through the gas injection port ( ), so that all the gas produced by fermentation is passed into the calcium hydroxide solution (mostly ), after a period of time, open the gas outlet to discharge the gas;

[0059] Step 5: Compare the mass change of calcium hydroxide solution before and after fermentation to get the mass of gas produced by fermentation. ;

[0060] Step 6: Correct for carbon emission mass.

[0061] In Example 4, since a closed container is used for fermentation, the aerobic bacteria therein die as the oxygen concentration decreases during the fermentation process. Therefore, there is a slight difference between the fermentation process in the container and the actual organic fertilizer fermentation, and the methane produced by the fermentation cannot be absorbed by calcium hydroxide. Therefore, the present invention has a post-correction method to correct the carbon emission quality; Figure 5 As shown, the specific steps are as follows:

[0062] Step 601: extract equal amounts of organic fertilizer from the sample organic fertilizer and the sampling source organic fertilizer, dilute them, and measure the ATP content of the two using the ATP bioluminescence method, which are respectively and ;

[0063] Step 602: Since the ATP content is proportional to the number of bacteria, an equation can be constructed:

[0064] ,

[0065] in, is the aerobic bacteria content; is the anaerobic bacteria content; represents the attenuation factor, which is obtained through experiments; because the lack of oxygen in a closed container will cause the death of aerobic bacteria, The production of oxygen depends on aerobic bacteria. According to the record in Microbial Physiology and Metabolism, one aerobic bacterium can consume Glucose. At this time, the glucose consumed per unit time is known, and the total fermentation time is known, so (2) and (3) can be rewritten as:

[0066] ,

[0067] Among them, there are unknown quantities , and , is the mass of carbon dioxide, is the mass of hydrogen sulfide, is the mass of gas produced by fermentation, is the conversion rate of hydrogen sulfide by anaerobic bacteria, is the conversion rate of carbon dioxide (which can be obtained by the glucose consumed per unit time and the total fermentation time). Combining equations (4), (5) and (6), we get and .

[0068] Step 603: Then the organic fertilizers extracted from the sampled source organic fertilizers are fermented to produce Can be obtained , the total organic fertilizer weight can be estimated to obtain the total Content, due to The generation of is complex, so in this embodiment, and One-to-one generation estimates it, and the mass is , the total mass of methane can be obtained by estimating the total weight in the same way;

[0069] Step 604: Calculate the total carbon emissions:

[0070] ,

[0071] in, is the total carbon emissions, is the total methane mass, is the total mass of carbon dioxide.
