Description

Technical Field

[0001] This invention relates to the field of compost quality testing technology, specifically to a method and system for evaluating the compost quality of traditional Chinese medicine waste. Background Technology

[0002] With the rapid development of the traditional Chinese medicine (TCM) industry, the amount of TCM waste generated continues to rise. Converting it into organic fertilizer through composting technology has become an important way to utilize resources. The composting of TCM waste first requires pretreatment: drying equipment is used to dry the waste, followed by crushing with a pulverizer, and then sieving with a sieve before composting. Existing technologies for assessing the quality of TCM waste compost mainly use a process of "process monitoring plus endpoint testing." During composting, the main monitoring parameters are the temperature, moisture content, and pH value of the waste pile. After composting, the focus shifts to testing the maturity and safety of the pile, using indicators such as carbon-to-nitrogen ratio, seed germination index, and heavy metal content, supplemented by electrochemical properties such as conductivity, to analyze compost quality.

[0003] For example, Chinese invention patent CN115304410B discloses a method for treating solid waste from traditional Chinese medicine. This method utilizes hyperspectral analysis to effectively monitor changes in lignin and cellulose content during composting. It combines liquid chromatography to determine the content standards of fermented medicinal residue samples and calculates the organic matter content of the residue as it changes with the number of fermentation days. Furthermore, it combines real-time monitoring of composting temperature during the fermentation process to calculate moisture content and carbon-nitrogen ratio to determine whether complete composting has been achieved and further regulates whether turning operations are required during the composting process.

[0004] For example, Chinese invention patent CN102661982B discloses a method for rapidly determining compost maturity by simply measuring the electrochemical properties of water-soluble organic matter. The measurement results are highly consistent with seed germination indicators.

[0005] The aforementioned technologies suffer from at least the following technical problems: Existing technologies often treat pretreatment as a routine operation before composting, failing to adjust pretreatment process parameters in a timely manner based on pretreatment efficiency. The pretreatment effect directly impacts the efficiency and final quality of the subsequent composting process. Existing technologies infer maturity through electrochemical properties, failing to capture complex organic matter transformation processes and lacking stratified monitoring and multi-dimensional parameter integration of the composting area. Composting is a continuous microbial metabolic process, with differences in physicochemical properties and component transformation at each stage. Relying solely on discrete endpoint detection cannot promptly identify abnormalities occurring in the early stages of composting, hindering refined quality assessment of the entire composting process. Summary of the Invention

[0006] To address the technical problems in the field of compost quality testing in existing technologies, this invention provides a method and system for evaluating the compost quality of traditional Chinese medicine waste. The technical solution is as follows:

[0007] On the one hand, a method for assessing the quality of composting of traditional Chinese medicine (TCM) waste is provided, including: Step 1: collecting TCM waste and pre-treating it; analyzing the treatment results after pre-treatment to determine whether to adjust the pre-treatment process parameters; analyzing the pre-treatment efficiency after adjusting the parameters to determine whether to compost the waste; Step 2: after composting, dividing the TCM waste into monitoring areas and monitoring the composting process parameters in each monitoring area to determine whether the parameters are effective and to provide early warning for the composting process; Step 3: selecting effective composting monitoring areas from the monitoring areas, evaluating the composting quality of each effective monitoring area, and integrating them to determine whether to adjust the pre-treatment process.

[0008] On the other hand, a traditional Chinese medicine (TCM) waste composting quality assessment system is provided, comprising: a TCM waste pretreatment module for collecting and pretreating TCM waste, analyzing the pretreatment efficiency after pretreatment to determine whether to adjust the TCM waste pretreatment process parameters for composting; a TCM waste monitoring area division module for dividing the TCM waste into monitoring areas after composting, monitoring the composting process parameters of each monitoring area to determine whether the composting process parameters of each monitoring area are effective, and providing early warning for the composting process; and a composting quality assessment module for selecting effective composting monitoring areas from the monitoring areas of the TCM waste, assessing the composting quality of each effective monitoring area, and integrating the results to determine whether to adjust the TCM waste pretreatment process.

[0009] The beneficial effects of the technical solutions provided in the embodiments of the present invention include at least the following:

[0010] (1) This invention provides a method and system for assessing the quality of composting of traditional Chinese medicine waste. By constructing a closed-loop system of dynamic adjustment of pretreatment parameters of traditional Chinese medicine waste, multi-dimensional monitoring of the composting process, and composting quality assessment, the system quantifies the total pretreatment efficiency index of traditional Chinese medicine waste in the pretreatment stage by using the pretreatment quality index. In the composting stage, effective composting areas are identified by real-time monitoring of composting process parameters. In the quality assessment stage, the composting quality assessment index is corrected by using biological indicators such as urease activity, acid phosphatase activity, and seed germination rate, combined with the total pretreatment quality index of traditional Chinese medicine waste. This system correlates pretreatment quality, composting process parameters, and final composting quality, solving the problems of data fragmentation and control lag in traditional assessment. The system integrates pretreatment, composting monitoring, and composting quality assessment through modular design, reducing human intervention errors and improving the efficiency and reliability of composting quality assessment.

[0011] (2) The present invention achieves dynamic optimization of the pretreatment process through the pretreatment quality index. The crushing and sieving time is adjusted according to the deviation between the pretreatment quality index and the pretreatment quality threshold of the Chinese medicine waste within the monitoring period. This avoids the problem of insufficient material adaptability caused by fixed parameters in the traditional Chinese medicine waste pretreatment. The implementation of the graded treatment mechanism of the remaining pretreatment materials improves the material utilization rate, reduces waste, and significantly enhances the stability and economy of the Chinese medicine waste pretreatment process.

[0012] (3) This invention improves the controllability of the composting process by regional monitoring and determination of effective composting areas for traditional Chinese medicine waste composting. By determining the range of each composting process parameter and statistically analyzing the qualified duration of each process parameter, the effective composting area is accurately identified, avoiding the problem of local anomalies being masked in the overall monitoring of traditional Chinese medicine waste composting. The setting of the number of effective composting areas further ensures the representativeness of the composting quality assessment results and provides a reliable data basis for subsequent composting quality assessment.

[0013] (4) This invention achieves continuous improvement in the quality of Chinese herbal medicine waste compost by optimizing the compost quality assessment index and pretreatment parameters. The index integrates biological activity indicators such as urease activity and seed germination rate with the total pretreatment quality index. The compost quality and pretreatment process are dynamically linked by the correction value. When the assessment index does not meet the standard, the system can reversely adjust the pretreatment parameters and update the database, forming a virtuous cycle from quality feedback to parameter iteration. This solves the problem of disconnect between pretreatment and final quality in traditional Chinese herbal medicine waste composting. Through continuous optimization of parameter accumulation, the compost maturity and stability are gradually improved. Attached Figure Description

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0021] Reference Figure 1 As shown, the first aspect of the present invention provides a method for evaluating the composting quality of traditional Chinese medicine waste, comprising: Step 1: collecting traditional Chinese medicine waste and pre-treating it; analyzing the treatment results after pre-treatment to determine whether to adjust the pre-treatment process parameters; analyzing the pre-treatment efficiency after adjusting the pre-treatment process parameters to compost the waste; Step 2: after composting, dividing the waste into monitoring areas and monitoring the composting process parameters of each monitoring area to determine whether the parameters are effective and providing an early warning for the composting process; Step 3: selecting effective composting monitoring areas from the monitoring areas, evaluating the composting quality of each effective monitoring area, and integrating them to determine whether to adjust the pre-treatment process.

[0022] Specifically, the pretreatment of traditional Chinese medicine (TCM) waste involves the following steps: First, the baseline drying time, baseline crushing time, and baseline sieving time are retrieved from the database. Second, the TCM waste is collected, and its initial moisture content is measured. Based on the initial moisture content of the current batch of TCM waste, the baseline drying time within the monitoring period is adjusted to obtain the defined moisture content corresponding to the baseline drying time. The database stores a mapping table between baseline drying time and defined moisture content. Inputting the baseline drying time into the database yields the defined moisture content. The moisture content deviation value of the current batch of TCM waste is obtained by dividing the difference between the initial moisture content and the defined moisture content by the defined moisture content corresponding to the baseline drying time. This deviation value is stored in the database. By mapping the drying time variation to the database, the change in drying time can be obtained by inputting the moisture content deviation of the Chinese herbal medicine waste into the database. The product of the basic drying time of the current batch of Chinese herbal medicine waste and the change in drying time is added to the basic drying time of the current batch of Chinese herbal medicine waste to obtain the basic drying time within the adjusted monitoring period. The Chinese herbal medicine waste within the monitoring period is dried based on the basic drying time, the dried Chinese herbal medicine waste is crushed based on the basic crushing time, and the crushed Chinese herbal medicine waste is sieved based on the basic sieving time. After the sieving of the Chinese herbal medicine waste within the monitoring period, the treatment results of the Chinese herbal medicine waste are analyzed to determine whether the pretreatment process parameters of the Chinese herbal medicine waste need to be adjusted.

[0023] The reason for adjusting the basic drying time within the monitoring period is as follows: If the initial moisture content of the current batch of Chinese herbal waste is less than the defined moisture content, drying according to the basic drying time will result in energy waste or over-drying of the Chinese herbal waste; if the initial moisture content of the current batch of Chinese herbal waste is greater than the defined moisture content, insufficient drying time will affect the efficiency of crushing and sieving of the Chinese herbal waste; adjusting the basic drying time within the monitoring period based on the initial moisture content of the current batch of Chinese herbal waste optimizes energy consumption costs while ensuring the pretreatment effect.

[0024] Furthermore, the treatment results of traditional Chinese medicine waste were analyzed. The specific analysis process was as follows: during the monitoring period, the pretreatment quality parameters of traditional Chinese medicine waste were obtained, including the screen clogging rate of traditional Chinese medicine waste, the proportion of compliant waste, and the energy consumption-to-mass ratio of crushing traditional Chinese medicine waste.

[0025] Screen clogging rate indicates the proportion of screen openings partially or completely blocked after sieving due to particle accumulation or adhesion of Chinese herbal waste. Image parameters of the sieve residue on the screen surface are obtained after sieving. By comparing the image of the residue with the initial image of the screen surface stored in the database, the number of grids covered by the residue is counted. The number of grids covered by the residue is divided by the total number of screen grids to obtain the screen clogging rate of Chinese herbal waste in the current monitoring period. The percentage of qualified waste refers to the percentage of the weight of the undersize material meeting the particle size requirements after sieving, relative to the original feed weight before pretreatment. This is used to quantify the control effect of the pretreatment process on the particle size compliance of the material. The percentage of qualified waste in the current monitoring period is recorded. The total weight of pre-treatment Chinese herbal medicine waste and the weight of compliant Chinese herbal medicine waste that passes screening after sieving are used to calculate the proportion of compliant Chinese herbal medicine waste in the current monitoring period. The energy consumption-to-mass ratio of pulverization represents the energy consumption per unit of compliant product. This is calculated by obtaining the operating power of the pulverizer for pulverizing Chinese herbal medicine waste in the current monitoring period, multiplying the operating power by the pulverizing time, and then dividing the total energy consumption by the weight of compliant Chinese herbal medicine waste that passes screening. This yields the energy consumption-to-mass ratio of pulverization for Chinese herbal medicine waste in the current monitoring period.

[0026] Based on the weighted ratio coefficients stored in the database, the ratios of the defined screen blockage rate to the screen blockage rate, the ratio of the proportion of compliant waste to its corresponding defined value, and the ratio of the defined crushing energy consumption to the crushing energy consumption are quantified. The effect of each ratio on the pretreatment quality index of Chinese medicine waste is then evaluated. By summarizing the effects of each ratio, the pretreatment quality index of Chinese medicine waste is obtained.

[0027] The pretreatment quality index for traditional Chinese medicine waste is used to evaluate the quality control effectiveness of the pretreatment process for traditional Chinese medicine waste. Its specific expression is:

[0028] ;

[0029] In the formula, PEI is the pretreatment quality index of Chinese herbal medicine waste, PA is the screen clogging rate of Chinese herbal medicine waste during the monitoring period, PW is the proportion of qualified waste of Chinese herbal medicine waste during the monitoring period, PR is the energy consumption-to-mass ratio of crushing of Chinese herbal medicine waste during the monitoring period, P_PA is the preset defined screen clogging rate in the database, P_PW is the preset defined proportion of qualified waste in the database, P_PR is the preset defined energy consumption-to-mass ratio of crushing in the database, pa1 is the preset weighted ratio coefficient of screen clogging rate in the database, pa2 is the preset weighted ratio coefficient of qualified waste proportion in the database, and pa3 is the preset weighted ratio coefficient of crushing energy consumption-to-mass ratio in the database.

[0030] The screen clogging rate is defined as the maximum permissible proportion of screen pores blocked by Chinese medicine waste material during the pretreatment of Chinese medicine waste. The proportion of qualified waste is defined as the minimum proportion of qualified Chinese medicine waste weight after pretreatment to the total processed amount. The energy consumption-to-mass ratio of crushing is defined as the maximum permissible energy consumption per unit of qualified product.

[0031] A higher screen clogging rate indicates poorer effective permeability of the screen during screening, which will affect screening efficiency and energy consumption. The proportion of compliant waste may decrease due to excessively large particle size or uneven distribution, requiring secondary crushing of non-compliant materials, leading to increased energy consumption during crushing and a significant increase in the energy-to-weight ratio of crushing. Conversely, a lower screen clogging rate results in a higher proportion of compliant waste, more uniform and compliant particle size in the crushing process, indicating a stable pretreatment crushing process. This reduces the number of rework cycles and energy waste in pretreatment of traditional Chinese medicine waste, indirectly lowering the energy consumption per unit of compliant product, and significantly reducing the energy-to-weight ratio of crushing. The screen clogging rate and energy-to-weight ratio of crushing are negatively correlated with the pretreatment quality index of traditional Chinese medicine waste, while the proportion of compliant waste is positively correlated with the pretreatment quality index of traditional Chinese medicine waste.

[0032] The weighted proportional coefficients for screen clogging rate and screen clogging ratio are used to quantify the impact of the ratio between screen clogging rate and screen clogging ratio on the pretreatment quality index of traditional Chinese medicine waste. The weighted proportional coefficients for the proportion of compliant waste and the ratio between ...

[0033] Specifically, the determination of whether to adjust the pretreatment process parameters of traditional Chinese medicine waste is as follows: During the monitoring period, the pretreatment quality index of traditional Chinese medicine waste is obtained. If the pretreatment quality index of traditional Chinese medicine waste is greater than or equal to the pretreatment quality threshold, it indicates that the treatment effect based on the current pretreatment process parameters has reached the expected pretreatment standard, and it is determined that the pretreatment process parameters of traditional Chinese medicine waste will not be adjusted. If the pretreatment quality index of traditional Chinese medicine waste is less than the pretreatment quality threshold, it indicates that the treatment effect based on the current pretreatment process parameters has not reached the expected pretreatment standard, and it is determined that the pretreatment process parameters of traditional Chinese medicine waste will be adjusted. Based on the deviation between the pretreatment quality index of traditional Chinese medicine waste and the pretreatment quality threshold, the crushing time of the crusher and the sieving time of the sieve are adjusted in the next monitoring period. The pretreatment quality threshold refers to the minimum value of the pretreatment quality index of traditional Chinese medicine waste.

[0034] Furthermore, the weight of the remaining TCM waste after sieving within the current monitoring period is obtained. If the weight of the remaining TCM waste after sieving within the current monitoring period is greater than or equal to the defined pretreatment weight, it indicates that pretreatment of the remaining TCM waste after sieving in the current batch is required. The defined pretreatment weight refers to the maximum weight of TCM waste processed during the pretreatment process. The remaining TCM waste after sieving is then marked as the TCM waste pretreatment target for the next monitoring period. If the weight of the remaining TCM waste after sieving within the current monitoring period is less than the defined pretreatment weight, it indicates that pretreatment of the remaining TCM waste after sieving in the current batch is not required. The pretreatment of the current batch of TCM waste is then terminated, and the remaining TCM waste after sieving in the current monitoring period is mixed into the next batch of TCM waste. The remaining TCM waste after sieving and the next batch of TCM waste are then marked as the TCM waste pretreatment targets for the next monitoring period. If, in the next monitoring period, the pretreatment target of traditional Chinese medicine (TCM) waste is the remaining TCM waste after sieving and the pretreatment quality index of the TCM waste is less than the pretreatment quality threshold, then the pulverizing time of the pulverizer and the sieving time of the sieving machine in the next monitoring period will be reduced to avoid over-pretreatment, reduce the energy consumption and wear of the equipment during pretreatment, reserve time for the pretreatment of the next batch of TCM waste, and avoid resource idleness caused by fixed long time consumption. If, in the next monitoring period, the pretreatment target of TCM waste is the remaining TCM waste after sieving and the next batch of TCM waste and the pretreatment quality index of the TCM waste is less than the pretreatment quality threshold, then the pulverizing time of the pulverizer and the sieving time of the sieving machine in the next monitoring period will be increased. Extending the pretreatment time can make the pulverization of TCM waste more thorough and the sieving more complete. Increasing the time can complete high-quality pretreatment and avoid resource waste caused by incomplete pretreatment.

[0035] The above-mentioned adjustment of the pulverizing time of the pulverizer and the sieving time of the sieve in the next monitoring cycle is as follows: The absolute value of the difference between the pretreatment quality threshold and the pretreatment quality index of the Chinese herbal medicine waste is processed, and the absolute difference is divided by the pretreatment quality threshold to obtain the deviation between the pretreatment quality index and the pretreatment quality threshold of the Chinese herbal medicine waste. A mapping table between the deviation between the pretreatment quality index and the pretreatment quality threshold of the Chinese herbal medicine waste and the change in pulverizing time in the next monitoring cycle is stored in the database. By inputting the deviation between the pretreatment quality index and the pretreatment quality threshold of the Chinese herbal medicine waste into the database, the change in pulverizing time in the next monitoring cycle can be obtained. If the pulverizing time in the next monitoring cycle is to be increased, the basic pulverizing time of the next monitoring cycle is added to the pulverizing time change in the next monitoring cycle to obtain the basic pulverizing time for the next monitoring cycle. If the pulverization time of the monitoring cycle is reduced, the basic pulverization time of the next monitoring cycle is subtracted from the change in pulverization time of the next monitoring cycle to obtain the basic pulverization time of the next monitoring cycle. The database stores a mapping table between the deviation value of the pretreatment quality index and the pretreatment quality threshold of Chinese herbal waste and the change in sieving time of the next monitoring cycle. By inputting the deviation value of the pretreatment quality index and the pretreatment quality threshold of Chinese herbal waste into the database, the change in sieving time of the next monitoring cycle can be obtained. If the sieving time of the next monitoring cycle is increased, the basic sieving time of the next monitoring cycle is added to the sieving time of the next monitoring cycle to obtain the basic sieving time of the next monitoring cycle. If the sieving time of the next monitoring cycle is decreased, the basic sieving time of the next monitoring cycle is subtracted from the change in sieving time of the next monitoring cycle to obtain the basic sieving time of the next monitoring cycle.

[0036] This invention achieves dynamic optimization of the pretreatment process through a pretreatment quality index. The crushing and sieving time is adjusted according to the deviation between the pretreatment quality index and the pretreatment quality threshold of the Chinese medicine waste within the monitoring period. This avoids the problem of insufficient material adaptability caused by fixed parameters in traditional Chinese medicine waste pretreatment. The implementation of a graded treatment mechanism for the remaining pretreatment materials improves material utilization, reduces waste, and significantly enhances the stability and economy of the Chinese medicine waste pretreatment process.

[0037] Update the pretreatment process parameters for traditional Chinese medicine (TCM) waste and pretreat the TCM waste for the next monitoring cycle. After the pretreatment of the current batch of TCM waste is completed, obtain the total number of pretreatments for the current batch. If the total number of pretreatments for the current batch of TCM waste is less than or equal to the pretreatment number threshold, it indicates that the pretreatment process parameters for the current batch of TCM waste are set reasonably. The pretreatment number threshold refers to the maximum number of pretreatments for TCM waste. Then, analyze the overall pretreatment quality index of the current batch of TCM waste. The overall pretreatment quality index of the current batch of TCM waste is based on the pretreatment quality of TCM waste in each monitoring cycle. The total pretreatment quality index is obtained by summing the pretreatment quality indices of Chinese herbal medicine waste in each monitoring period and dividing the sum by the total number of pretreatments for the current batch of Chinese herbal medicine waste. If the total number of pretreatments for the current batch of Chinese herbal medicine waste exceeds the pretreatment threshold, an early warning is issued for the pretreatment process of the current batch of Chinese herbal medicine waste. This indicates that the pretreatment process parameters for the current batch of Chinese herbal medicine waste have insufficient adaptability, which may lead to over-processing of materials. The pretreatment process parameters and material characteristics of the current batch of Chinese herbal medicine waste are checked, and the pretreatment parameter thresholds are recalibrated to avoid ineffective recycling.

[0038] Specifically, the composting process for traditional Chinese medicine (TCM) waste involves the following steps: Based on the weight of the pre-treated TCM waste, the database is used to match the required weight of biochar, the volume of microbial inoculants, and the weight of enzyme agents to be added. The database stores a mapping table between the weight of TCM waste and the weight of biochar added during composting; inputting the weight of TCM waste into the database will yield the required biochar weight. Similarly, the database stores a mapping table between the weight of TCM waste and the volume of microbial inoculants added during composting; inputting the weight of TCM waste into the database will yield the required volume of microbial inoculants. Finally, the database stores a mapping table between the weight of TCM waste and the weight of enzyme agents added during composting. By inputting the weight of the Chinese herbal medicine waste into the database, the weight of the enzyme agent added during the composting process can be obtained. Biochar, microbial agents, and enzyme agents are added to the pretreated Chinese herbal medicine waste, and the compost mixture is stirred. Pure water is added to control the moisture content of the compost mixture to a moisture content threshold, which is the minimum moisture content during the composting process. By adding a certain proportion of pure water to the compost mixture multiple times, the moisture content of the compost mixture is controlled to the moisture content threshold. Before adding pure water, the moisture content of the compost mixture is collected. Based on the current weight of the compost mixture, the difference between the moisture content threshold and the current moisture content is multiplied by the current weight of the compost mixture. Then, the product is divided by 1 and the difference between the moisture content threshold and the current moisture content is subtracted to obtain the amount of pure water added.

[0039] Figure 3 This is a schematic diagram of the pretreatment process for traditional Chinese medicine waste provided in this embodiment of the invention. By collecting traditional Chinese medicine waste, adjusting the basic drying time within the monitoring period based on the initial moisture content of the current batch of traditional Chinese medicine waste, and pretreating the traditional Chinese medicine waste, the treatment results of the traditional Chinese medicine waste are analyzed after the pretreatment is completed, the quality index is calculated based on the pretreatment quality parameters, and it is determined whether the pretreatment process parameters of the traditional Chinese medicine waste need to be adjusted. After the pretreatment of the traditional Chinese medicine waste is completed, the traditional Chinese medicine waste is composted.

[0040] Furthermore, the composting process parameters of each monitoring area containing the traditional Chinese medicine waste are monitored. The specific analysis process is as follows: Different monitoring areas for the traditional Chinese medicine waste are set up. After a basic composting period, the composting process parameters of each monitoring area are collected during the composting monitoring period, including moisture content, pH value, and salt concentration. It is then determined whether the composting process parameters of each monitoring area meet the first condition during the composting monitoring period. If a monitoring area meets the first condition during the composting monitoring period, it indicates that the composting process parameters of that area are within a safe range during the composting monitoring period, and the monitoring area is marked as a qualified monitoring area. If a monitoring area does not meet the first condition during the composting monitoring period, it indicates that the composting process parameters of that area are not within a safe range during the composting monitoring period. Within a safe range, the monitoring area is marked as an abnormal monitoring area for process parameters; statistically analyze and continuously monitor qualified monitoring areas for each process parameter to determine whether the composting process parameters of each composting monitoring area to which the Chinese medicine waste belongs are valid; the first condition refers to the monitoring area having a moisture content less than the upper limit of the defined moisture content range and greater than the lower limit of the defined moisture content range, a pH value less than the upper limit of the defined pH value range and greater than the lower limit of the defined pH value range, and a salt concentration less than or equal to the salt concentration threshold during the composting monitoring period; the moisture content range represents the target range of moisture content during the composting process, the pH value range represents the target range of pH value during the composting process, and the salt concentration threshold represents the maximum allowable salt concentration during the composting process.

[0041] The aforementioned setting up different monitoring zones for traditional Chinese medicine waste refers to setting up different monitoring zones from the spatial dimension of the pile. Vertically, it is divided into three layers according to the height of the pile. The upper layer extends downwards from the surface of the traditional Chinese medicine waste pile to one-third of the pile height. The upper layer is the surface layer of the pile that is in direct contact with the external environment and is significantly affected by atmospheric temperature and airflow disturbances, making it prone to rapid temperature fluctuations and humidity evaporation. The monitoring points in the upper layer can capture the immediate impact of environmental factors on the compost surface. The middle layer extends downwards from one-third of the height of the traditional Chinese medicine waste pile to one-third of the pile height. The middle layer, located at one-third of the height of the compost pile, is the core reaction zone. The material density is moderate, heat generated by microbial activity does not easily dissipate, temperature stability is strong, and moisture and oxygen distribution are relatively balanced. Monitoring points in the middle layer can reflect the mainstream state of the composting degradation process. The lower layer extends downwards to one-third of the height from two-thirds of the height of the medicinal herb waste pile. Affected by gravity, leachate easily accumulates in this area, resulting in higher humidity and greater difficulty in oxygen penetration. Monitoring points in the lower layer can capture the characteristics of material migration and environmental changes deep within the pile. The horizontal layer... The compost pile is divided into nine monitoring points based on its length and width. Along the length of the pile, it is further divided into three equal parts at one-third intervals, forming two longitudinal dividing lines. Along the width of the pile, it is also divided into three equal parts at one-third intervals, forming two transverse dividing lines. These longitudinal and transverse dividing lines intersect, dividing the pile plane into nine equally sized grid areas. The central grid monitoring point is located at the geometric center of the pile plane, reflecting the core parameters of the area with the densest material and the most vigorous microbial activity. Four corner grid monitoring points are located near the edges of the pile, focusing on monitoring the boundary areas in contact with the external environment and capturing the edge effects of temperature and humidity. Four side grid monitoring points are distributed along the centerline of the pile's length and width, reflecting parameter changes in the transition area between the pile's edge and center. The three-layer vertical division accurately corresponds to the environmental gradient from the surface to the deeper layers of the pile, while the nine-grid horizontal points comprehensively cover the core and edge areas of the planar region. This equal spatial coverage ensures the representativeness of the monitoring data, effectively capturing parameter differences at different locations within the pile and providing sample data for subsequent composting process analysis.

[0042] Specifically, the validity of composting process parameters in each monitoring area for traditional Chinese medicine waste is determined as follows: The validity period of process parameters in each monitoring area is obtained. The validity period refers to the duration during which each composting process parameter meets the first condition. If the validity period of a monitoring area exceeds the threshold, it indicates that the composting process parameter has reached the target stable duration, and the monitoring area is marked as a valid composting area. The compost quality of the valid monitoring area is then statistically analyzed and evaluated. If the validity period of a monitoring area is less than or equal to the threshold, it indicates that the composting process parameter has not yet reached the target stable duration. Monitoring of the monitoring area continues until the composting of the traditional Chinese medicine waste is completed. The threshold represents the minimum validity period of the process parameter. Statistical analysis and monitoring of each monitoring area can distinguish valid composting areas, reducing redundant manpower input. Timely determination of the validity of composting process parameters avoids resource waste during compost quality assessment due to parameter failure.

[0043] Figure 4 This is a schematic diagram of the composting process monitoring and effective composting determination process provided in this embodiment of the invention. Different monitoring areas for traditional Chinese medicine waste are set up. After the basic composting time, the composting process parameters of each monitoring area of ​​traditional Chinese medicine waste are collected within the composting monitoring period. By judging whether the composting process parameters meet the first condition, each monitoring area is divided into a process parameter qualified monitoring area and a process parameter abnormal monitoring area. The qualified process parameter duration of the process parameter qualified monitoring area is counted. By judging whether the qualified process parameter duration of the process parameter qualified monitoring area is greater than the threshold, the process parameter qualified monitoring area with a process parameter qualified duration greater than the threshold is marked as an effective composting monitoring area, thereby screening out the effective composting monitoring areas.

[0044] This invention improves the controllability of the composting process by regional monitoring and determination of effective composting areas for traditional Chinese medicine waste. By determining the range of each composting process parameter and statistically analyzing the qualified duration of each process parameter, it accurately identifies effective composting areas, avoiding the problem of local anomalies being masked in the overall monitoring of traditional Chinese medicine waste composting. The setting of the number of effective composting areas further ensures the representativeness of the composting quality assessment results, providing a reliable data foundation for subsequent composting quality assessments.

[0045] Specifically, the compost quality of each effective compost monitoring area was assessed. The specific analysis process was as follows: compost quality assessment data of traditional Chinese medicine waste in the effective compost monitoring areas were collected. The compost quality assessment data included: urease activity, acid phosphatase activity, and germination rate of cabbage seeds in the effective compost monitoring areas.

[0046] Urease activity refers to the ability of urease in compost materials within the effective compost monitoring area to catalyze the decomposition of urea into ammonia and carbon dioxide. Compost samples from the effective compost monitoring area are prepared into an extract, urea substrate is added, and the mixture is reacted in a constant-temperature water bath for a certain time. The ammonia content generated during the reaction is then measured to determine the urease activity. The reaction time is determined by relevant personnel in the field. Acid phosphatase activity refers to the ability of acid phosphatase in compost materials within the effective compost monitoring area to catalyze the hydrolysis of organic phosphorus compounds into inorganic phosphorus. Compost samples from the effective compost monitoring area are reacted with a sodium phthalate solution under acidic conditions, and the activity is measured per unit mass of sample. The amount of inorganic phosphorus released from the sample is used to determine the acid phosphatase activity. The germination rate of cabbage seeds refers to the proportion of germinating cabbage seeds in the compost extract within the effective compost monitoring area, reflecting the maturity and biosafety of the compost. Compost samples from the effective compost monitoring area are taken and mixed with pure water at a set ratio to prepare the extract. Cabbage seeds are placed on filter paper soaked in the extract and cultured for 72 hours at a set temperature and light intensity. The proportion of germinated cabbage seeds to the total number of cabbage seeds is counted. The ratio of compost sample to pure water, the set temperature, and the set light intensity are determined by relevant personnel in the field.

[0047] By using pre-set proportional weighting coefficients in the database, the influence of the proportional relationships between three types of parameters and their corresponding threshold values ​​on the compost quality assessment index of the effective compost monitoring area is quantified. Specifically, these relationships are: the proportional relationship between urease activity and threshold urease activity, the proportional relationship between acid phosphatase activity and threshold acid phosphatase activity, and the proportional relationship between cabbage seed germination rate and threshold cabbage seed germination rate. The influence of these three types of proportional relationships is weighted accordingly and summarized to obtain the compost quality assessment index of the effective compost monitoring area.

[0048] The compost quality assessment index for the effective compost monitoring area is used to characterize the compost quality of traditional Chinese medicine waste in the effective compost monitoring area. The specific expression is as follows:

[0049] ;

[0050] In the formula, TEI is the compost quality assessment index of the effective compost monitoring area, TU is the urease activity of the effective compost monitoring area, TA is the acid phosphatase activity of the effective compost monitoring area, TG is the germination rate of cabbage seeds in the effective compost monitoring area, T_TU is the preset defined urease activity in the database, T_TA is the preset defined acid phosphatase activity in the database, T_TG is the preset defined germination rate of cabbage seeds in the database, ta1 is the preset weighting coefficient of urease activity ratio in the database, ta2 is the preset weighting coefficient of acid phosphatase activity ratio in the database, and ta3 is the preset weighting coefficient of cabbage seed germination rate ratio in the database.

[0051] Urease activity is defined as the minimum baseline value that urease activity must reach during the composting process. Acid phosphatase activity is defined as the minimum activity level at which organic phosphorus is hydrolyzed into inorganic phosphorus per hour per unit mass of compost. The germination rate of cabbage seeds is defined as the minimum requirement for the normal germination rate of compost extract under set culture conditions.

[0052] Higher urease activity indicates a stronger ability of microorganisms in the Chinese herbal medicine waste compost to decompose and metabolize nitrogen-containing organic matter, resulting in more complete nitrogen release and facilitating the subsequent use of the waste as fertilizer to provide nitrogen nutrition. Higher acid phosphatase activity indicates a higher conversion efficiency of organic phosphorus to available phosphorus in the Chinese herbal medicine waste compost, providing crops with more absorbable phosphorus nutrition. The compost also decomposes more thoroughly, leading to more complete decomposition of harmful substances and a higher germination rate of cabbage seeds. A higher germination rate of cabbage seeds indicates a lower content of harmful substances in the Chinese herbal medicine waste compost and a weaker inhibitory effect on crop growth. A lower germination rate of cabbage seeds indicates the presence of toxic substances in the Chinese herbal medicine waste compost, which inhibits microbial activity, thus leading to a decrease in the enzyme activities of urease and acid phosphatase. Urease activity, acid phosphatase activity, and cabbage seed germination rate are all positively correlated with the compost quality assessment index of the effective compost monitoring area.

[0053] The weighted coefficients for urease activity and acid phosphatase activity are used to quantify the influence of the ratio between urease activity and its threshold value in the effective compost monitoring area on the compost quality assessment index of the effective compost monitoring area. The weighted coefficients for acid phosphatase activity and cabbage seed germination rate are also used to quantify the influence of this ratio on the compost quality assessment index. The values ​​for all three weighted coefficients range from 0 to 1. The database pre-stores the mapping relationships between urease activity, acid phosphatase activity, and cabbage seed germination rate and their corresponding weighted coefficients. Specifically, when urease activity, acid phosphatase activity, and cabbage seed germination rate are input, the database can directly retrieve and output the corresponding weighted coefficients.

[0054] Based on the total pretreatment quality index of the current batch of traditional Chinese medicine (TCM) waste, the corrected value of the composting quality assessment index of TCM waste stored in the database is obtained. The database stores a mapping table between the total pretreatment quality index of TCM waste and the corrected value of the composting quality assessment index. By inputting the total pretreatment quality index of TCM waste into the database, the corrected value of the composting quality assessment index of TCM waste can be obtained. The composting quality assessment indices of each effective composting monitoring area are accumulated, the accumulated result is divided by the number of effective composting monitoring areas, and multiplied by the corrected value of the composting quality assessment index of TCM waste to obtain the composting quality assessment index of TCM waste. The composting quality assessment index of TCM waste is used to characterize the composting quality of TCM waste.

[0055] Specifically, the determination of whether to adjust the pretreatment process of traditional Chinese medicine (TCM) waste is as follows: After the composting of TCM waste is completed, if the number of effective composting monitoring areas is less than the defined number of effective composting areas (the minimum number of effective composting areas), then the current batch of TCM waste compost is marked as ineffective composting, and an early warning is issued for the difference in composting monitoring areas; if the number of effective composting monitoring areas is greater than or equal to the defined number of effective composting areas, then the current batch of TCM waste compost is marked as effective composting, and the composting quality assessment index of TCM waste is obtained. If the composting quality assessment index of TCM waste is greater than or equal to the composting quality assessment index threshold, the table is displayed. If the composting quality of the current batch of Chinese herbal medicine waste reaches the expected composting quality, then the basic drying time, basic crushing time, and basic sieving time in the pretreatment process parameters of the current batch of Chinese herbal medicine waste are recorded in the database. If the composting quality assessment index of the Chinese herbal medicine waste is less than the composting quality assessment index threshold, it means that the composting quality of the current batch of Chinese herbal medicine waste has not reached the expected composting quality. Then, based on the deviation between the composting quality assessment index of the Chinese herbal medicine waste and the composting quality assessment index threshold, the basic drying time, basic crushing time, and basic sieving time in the pretreatment process parameters of the next batch of Chinese herbal medicine waste are increased and adjusted, and the adjusted pretreatment process parameters of the Chinese herbal medicine waste are recorded in the database.

[0056] Furthermore, early warnings are issued for differences in compost monitoring areas. Specifically, the warnings include: sending a notification to the management department that there are significant differences in the quality of the current batch of traditional Chinese medicine waste compost; suspending the pretreatment of the next batch of compost; verifying the parameters of each monitoring area to analyze the causes of abnormal compost quality; and recalibrating the classification standards of each monitoring area and the parameter adjustment strategies of the pretreatment process to prevent the differences from continuing to expand and affecting the subsequent composting effect of traditional Chinese medicine waste.

[0057] The aforementioned compost quality assessment index threshold refers to the minimum value of the compost quality assessment index for traditional Chinese medicine waste. The difference between the compost quality assessment index threshold and the compost quality assessment index for traditional Chinese medicine waste is divided by the minimum value of the compost quality assessment index threshold to obtain the deviation value between the compost quality assessment index and the minimum value of ... The deviation value of the quality assessment index threshold yields the increase in basic crushing time. This allows for the acquisition of the basic crushing time in the pretreatment parameters of the next batch of traditional Chinese medicine waste. Adding this increase to the basic crushing time in the pretreatment parameters of the next batch of traditional Chinese medicine waste results in the increased and adjusted basic crushing time. The database stores a mapping table between the deviation value of the compost quality assessment index and its threshold, and the increase in basic sieving time. Inputting the deviation value of the compost quality assessment index and its threshold into the database yields the increase in basic sieving time. This allows for the acquisition of the basic sieving time in the pretreatment parameters of the next batch of traditional Chinese medicine waste. Adding this increase to the basic sieving time in the pretreatment parameters of the next batch of traditional Chinese medicine waste results in the increased and adjusted basic sieving time. This enables the adjustment of the basic drying time, basic crushing time, and basic sieving time in the pretreatment parameters of the next batch of traditional Chinese medicine waste.

[0058] The above-mentioned method, by comparing the composting quality assessment index and the threshold of the composting quality assessment index of traditional Chinese medicine (TCM) waste, achieves closed-loop feedback adjustment of the parameters in the pretreatment process of TCM waste. This can specifically compensate for the deficiencies of the current parameters, quickly correct the deviations of the pretreatment process parameters, and reduce the risk of continuous batches of TCM waste failing to meet composting quality standards. By recording effective parameters in the database, the data sample is increased, and the optimal pretreatment parameters corresponding to different batches of TCM waste can be extracted from the database. This ensures that the pretreatment parameters are aligned with the material characteristics and composting requirements of TCM waste, gradually improving the matching degree between the pretreatment process parameters and the actual treatment, thereby improving the operating efficiency and resource utilization of the pretreatment system. Through closed-loop feedback adjustment, the qualified parameters are directly reused, reducing the cost of ineffective parameter trial and error and reducing the energy waste caused by repeated adjustments of equipment parameters. This ensures both real-time control of composting quality and promotes long-term optimization of pretreatment parameters, achieving a synergistic improvement in composting quality stability, parameter adaptability, and system economy.

[0059] Figure 5 This is a schematic diagram of the composting quality assessment and pretreatment parameter optimization process provided in this embodiment of the invention. It involves collecting composting quality assessment data of traditional Chinese medicine (TCM) waste from an effective composting monitoring area, calculating the composting quality assessment index for that area, combining this with the total pretreatment quality index based on the current batch of TCM waste, obtaining the corrected composting quality assessment index value for TCM waste stored in the database, correcting the TCM waste's composting quality assessment index, and obtaining the TCM waste's composting quality assessment index. If the TCM waste's composting quality assessment index is greater than or equal to a composting quality assessment index threshold, then the pretreatment process parameters for the current batch of TCM waste are entered into the database; if the TCM waste's composting quality assessment index is less than the composting quality index threshold, then the pretreatment process parameters for the next batch of TCM waste are adjusted, and the adjusted TCM waste pretreatment process parameters are entered into the database.

[0060] This invention achieves continuous improvement in the compost quality of traditional Chinese medicine waste through the linkage optimization of compost quality assessment index and pretreatment parameters. The index integrates biological activity indicators such as urease activity and seed germination rate with the total pretreatment quality index, and dynamically correlates compost quality with the pretreatment process through correction values. When the assessment index fails to meet the standard, the system can reversely adjust the pretreatment parameters and update the database, forming a virtuous cycle from quality feedback to parameter iteration. This solves the problem of disconnect between pretreatment and final quality in traditional Chinese medicine waste composting. Through continuous optimization and parameter accumulation, the compost maturity and stability are gradually improved.

[0061] This invention provides a method and system for assessing the quality of composting of traditional Chinese medicine (TCM) waste. By constructing a closed-loop system integrating dynamic adjustment of TCM waste pretreatment parameters, multi-dimensional monitoring of the composting process, and compost quality assessment, the system quantifies the overall pretreatment efficiency index in the TCM waste pretreatment stage using a pretreatment quality index. In the composting stage, effective composting areas are identified through real-time monitoring of composting process parameters. In the quality assessment stage, biological indicators such as urease activity, acid phosphatase activity, and seed germination rate are used, combined with the overall pretreatment quality index of the TCM waste, to correct the compost quality assessment index. This system correlates pretreatment quality, composting process parameters, and final compost quality, solving the problems of data fragmentation and lagging regulation in traditional assessments. The system integrates pretreatment, composting monitoring, and compost quality assessment through modular design, reducing human intervention errors and improving the efficiency and reliability of compost quality assessment.

[0062] Reference Figure 2 As shown, the second aspect of the present invention provides a system for evaluating the quality of composting of traditional Chinese medicine waste, comprising: a module for pretreatment of traditional Chinese medicine waste, a module for dividing monitoring areas of traditional Chinese medicine waste, a module for evaluating the composting quality of the monitoring areas, and a database.

After pretreatment, it analyzes the pretreatment efficiency to determine whether to adjust the pretreatment process parameters for composting.
