Description

Technical Field

[0001] The present invention relates to the technical field of compost quality testing, and in particular to a method and system for evaluating the quality of compost of traditional Chinese medicine waste. Background Art

[0002] With the rapid development of the traditional Chinese medicine industry, the amount of traditional Chinese medicine waste generated continues to rise. Converting it into organic fertilizer through composting technology has become an important way to utilize resources. The composting of traditional Chinese medicine waste first needs to undergo pretreatment. The traditional Chinese medicine waste is dried with drying equipment, crushed with a crusher, screened with screening equipment, and then composted. The existing technology for evaluating the quality of traditional Chinese medicine waste compost mostly uses the "process monitoring plus endpoint detection" evaluation process to evaluate the compost quality. During the composting process, the temperature, moisture content and pH value of the traditional Chinese medicine waste pile are mainly monitored. After the composting is completed, the focus is on detecting the maturity and safety of the pile. The compost quality is analyzed by detecting indicators such as carbon-nitrogen ratio, seed germination index and heavy metal content, supplemented by electrochemical properties such as conductivity.

[0003] For example, a Chinese invention patent with announcement number CN115304410B discloses a method for treating solid waste of Chinese herbal medicine. The method uses a hyperspectral measurement method to effectively monitor the changes in the content of lignin and cellulose during the composting process, combines liquid chromatography chemical determination of the fermentation samples of the medicinal residue to obtain the content standard, and calculates the organic ratio of the medicinal residue that changes with the number of fermentation days; and combines the real-time monitoring of the compost fermentation temperature during the composting fermentation process to calculate the moisture content and carbon-nitrogen ratio to determine whether the compost is fully mature, and further regulate whether the composting process is to perform the compost turning operation.

[0004] For example, Chinese invention patent publication number 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 above-mentioned technologies have at least the following technical problems: the existing technologies mostly regard pretreatment as routine operations before composting, and are unable to adjust the pretreatment process parameters in time through pretreatment efficiency. The pretreatment effect will directly affect the efficiency and final quality of the subsequent composting process; the existing technologies infer maturity through electrochemical properties, and are unable to capture the complex organic matter transformation process, and lack stratified monitoring of the composting area and multi-dimensional parameter integration; composting is a continuous microbial metabolic process, and there are differences in the physical and chemical properties and component transformations at each stage. Relying solely on discrete endpoint detection, it is impossible to timely detect abnormalities in the early stages of composting, which is not conducive to refined quality assessment of the entire composting process. Summary of the Invention

[0006] In order to solve the technical problems in the field of compost quality testing technology in the prior art, the embodiment of the present invention provides a method and system for evaluating the quality of Chinese medicine waste compost. The technical solution is as follows: On the one hand, a method for evaluating the compost quality of traditional Chinese medicine waste is provided, comprising: step 1, collecting traditional Chinese medicine waste and pre-treating the traditional Chinese medicine waste, analyzing the treatment results of the traditional Chinese medicine waste after the pre-treatment is completed, so as to determine whether the pre-treatment process parameters of the traditional Chinese medicine waste are adjusted, and after the adjustment of the pre-treatment process parameters of the traditional Chinese medicine waste is completed, analyzing the pre-treatment efficiency of the traditional Chinese medicine waste, so as to compost the traditional Chinese medicine waste; step 2, after the composting treatment is completed, dividing the monitoring area of ​​the traditional Chinese medicine waste, monitoring the composting process parameters of each monitoring area to which the traditional Chinese medicine waste belongs, so as to determine whether the composting process parameters of each composting monitoring area to which the traditional Chinese medicine waste belongs are valid, and issuing an early warning for the composting treatment process; step 3, screening out each effective composting monitoring area from each monitoring area to which the traditional Chinese medicine waste belongs, evaluating the compost quality of each effective composting monitoring area, and integrating them, so as to determine whether the pre-treatment process of the traditional Chinese medicine waste is adjusted.

[0007] On the other hand, a system for evaluating the composting quality of traditional Chinese medicine waste is provided, comprising: a traditional Chinese medicine waste pretreatment module, which is used to collect traditional Chinese medicine waste and pretreat the traditional Chinese medicine waste, and analyze the pretreatment efficiency of the traditional Chinese medicine waste after the pretreatment is completed, so as to determine whether to adjust the parameters of the traditional Chinese medicine waste pretreatment process, so as to compost the traditional Chinese medicine waste; a module for dividing traditional Chinese medicine waste monitoring areas, which is used to divide the monitoring areas of the traditional Chinese medicine waste after the composting treatment is completed, monitor the composting process parameters of each monitoring area to which the traditional Chinese medicine waste belongs, so as to determine whether the composting process parameters of each composting monitoring area to which the traditional Chinese medicine waste belongs are valid, and issue an early warning for the composting treatment process; a module for evaluating the composting quality of the composting monitoring areas, which is used to screen out each effective composting monitoring area from each monitoring area to which the traditional Chinese medicine waste belongs, evaluate the compost quality of each effective composting monitoring area, and integrate them, so as to determine whether to adjust the pretreatment process of the traditional Chinese medicine waste.

[0008] The beneficial effects brought about by the technical solution provided by the embodiment of the present invention include at least: (1) The present invention provides a method and system for evaluating the quality of composting of traditional Chinese medicine waste. By constructing a closed-loop system for dynamic adjustment of traditional Chinese medicine waste pretreatment parameters, multi-dimensional monitoring of the composting process and compost quality evaluation, in the pretreatment stage of traditional Chinese medicine waste, the total pretreatment efficiency index of the traditional Chinese medicine waste pretreatment process is quantified by the pretreatment quality index; in the composting stage, the effective composting area is identified by real-time monitoring of the composting process parameters; in the quality evaluation stage, the compost quality evaluation index is corrected by combining the urease activity, acid phosphatase activity and seed germination rate biological indicators with the total pretreatment quality index of traditional Chinese medicine waste, and the pretreatment quality, composting process parameters and final compost quality are correlated, thereby solving the problems of data fragmentation and regulation lag in each link in traditional evaluation. The system integrates pretreatment, composting monitoring and compost quality evaluation through modular design, reduces human intervention errors, and improves the efficiency and reliability of compost quality evaluation.

[0009] (2) The present invention realizes dynamic optimization of the pretreatment process through the pretreatment quality index. The crushing and screening time are adjusted according to the deviation value between the pretreatment quality index of the traditional Chinese medicine waste and the pretreatment quality threshold within the monitoring period, thereby avoiding 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 residual pretreatment material improves the material utilization rate, reduces waste, and significantly improves the stability and economy of the traditional Chinese medicine waste pretreatment link.

[0010] (3) The present invention improves the controllability of the composting process by regionalizing the monitoring of TCM waste composting and determining the effective composting areas. By determining the intervals of each composting process parameter and counting the qualified time of the process parameters, the effective composting areas are accurately identified, thus avoiding the problem of local anomalies being masked in the overall monitoring of traditional TCM waste composting. The setting of defining the number of effective composting areas further ensures the representativeness of the compost quality assessment results and provides a reliable data basis for subsequent compost quality assessment.

[0011] (4) The present invention achieves continuous improvement of the quality of TCM waste compost through the linkage optimization of compost quality evaluation 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 associates the compost quality with the pretreatment process through correction values; when the evaluation 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, solving the problem of disconnection between pretreatment and final quality in traditional TCM waste composting, and gradually improving the maturity and stability of the compost by continuously optimizing parameter accumulation.

DETAILED DESCRIPTION

[0014] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0015] Reference Figure 1 As shown, the first aspect of the present invention provides a method for evaluating the compost quality of traditional Chinese medicine waste, including: step 1, collecting traditional Chinese medicine waste and pre-treating the traditional Chinese medicine waste, analyzing the treatment results of the traditional Chinese medicine waste after the pretreatment is completed, so as to determine whether to adjust the pretreatment process parameters of the traditional Chinese medicine waste, after the adjustment of the pretreatment process parameters of the traditional Chinese medicine waste is completed, analyzing the pretreatment efficiency of the traditional Chinese medicine waste, and composting the traditional Chinese medicine waste; step 2, after the composting treatment is completed, dividing the monitoring area of ​​the traditional Chinese medicine waste, monitoring the composting process parameters of each monitoring area to which the traditional Chinese medicine waste belongs, so as to determine whether the composting process parameters of each composting monitoring area to which the traditional Chinese medicine waste belongs are valid, and issuing an early warning for the composting treatment process; step 3, screening out each effective composting monitoring area from each monitoring area to which the traditional Chinese medicine waste belongs, evaluating the compost quality of each effective composting monitoring area, and integrating them, so as to determine whether to adjust the pretreatment process of the traditional Chinese medicine waste.

[0016] Specifically, the traditional Chinese medicine waste is pretreated, and the specific processing process is: obtain the basic drying time, basic crushing time and basic screening time stored in the database; collect traditional Chinese medicine waste, collect the initial moisture content of the traditional Chinese medicine waste, adjust the basic drying time within the monitoring period based on the initial moisture content of the current batch of traditional Chinese medicine waste, and obtain the defined moisture content corresponding to the basic drying time. The database stores a mapping table of basic drying time and defined moisture content. The defined moisture content can be obtained by inputting the basic drying time in the database. The difference between the initial moisture content and the defined moisture content is divided by the defined moisture content corresponding to the basic drying time to obtain the moisture content deviation value of the current batch of traditional Chinese medicine waste. The moisture content deviation value of traditional Chinese medicine waste is stored in the database. The variation of drying time can be obtained by inputting the moisture content deviation value of traditional Chinese medicine waste into the database, and the basic drying time of the current batch of traditional Chinese medicine waste is multiplied by the variation of drying time, and the product result is added to the basic drying time of the current batch of traditional Chinese medicine waste to obtain the basic drying time within the monitoring period after adjustment; the traditional Chinese medicine waste within the monitoring period is dried based on the basic drying time, the dried traditional Chinese medicine waste is crushed based on the basic crushing time, and the crushed traditional Chinese medicine waste is sifted based on the basic screening time; after the screening of the traditional Chinese medicine waste within the monitoring period, the treatment results of the traditional Chinese medicine waste are analyzed to determine whether the pretreatment process parameters of the traditional Chinese medicine waste are adjusted.

[0017] The above-mentioned basic drying time is adjusted within the monitoring period. The specific reasons are: if the initial moisture content of the current batch of traditional Chinese medicine waste is less than the defined moisture content, drying according to the basic drying time will cause energy waste or over-drying of the traditional Chinese medicine waste; if the initial moisture content of the current batch of traditional Chinese medicine waste is greater than the defined moisture content, the drying time is insufficient, which will affect the crushing and screening efficiency of the traditional Chinese medicine waste; based on the initial moisture content of the current batch of traditional Chinese medicine waste, the basic drying time within the monitoring period is adjusted to achieve optimization of energy consumption costs while ensuring the pretreatment effect.

[0018] Furthermore, the treatment results of traditional Chinese medicine waste were analyzed. The specific analysis process was as follows: within the monitoring period, the pretreatment quality parameters of traditional Chinese medicine waste were obtained, including the screen blockage rate of traditional Chinese medicine waste, the proportion of traditional Chinese medicine waste that met the standards, and the crushing energy consumption-to-mass ratio of traditional Chinese medicine waste.

[0019] The sieve blockage rate indicates the proportion of sieve holes that are partially or completely blocked on the sieve due to the accumulation of particles of Chinese medicine waste or the adhesion of Chinese medicine waste after the screening process is completed. After the screening is completed, the image parameters of the sieved residue on the sieve surface are obtained. By comparing the image of the sieved residue on the sieve surface with the initial image of the sieve surface stored in the database, the number of grids covered by the sieved residue is counted, and the number of grids covered by the sieved residue is divided by the total number of grids on the sieve to obtain the sieve blockage rate of Chinese medicine waste in the current monitoring period; the proportion of qualified waste refers to the percentage of the weight of the sieve undersize that meets the particle size requirements after the Chinese medicine waste is screened to the original feed weight before pretreatment. It is used to quantify the control of the pretreatment process on the compliance effect of the material particle size and record the current monitoring period in the pretreatment process. The total weight of traditional Chinese medicine waste before treatment and the weight of qualified traditional Chinese medicine waste screened out after screening, and the weight of qualified traditional Chinese medicine waste screened out after screening divided by the total weight of traditional Chinese medicine waste before pretreatment are used as the proportion of qualified traditional Chinese medicine waste in the current monitoring period; the crushing energy consumption-to-mass ratio represents the energy consumption per unit qualified product, and the operating power of the crusher for crushing traditional Chinese medicine waste in the current monitoring period is obtained, and the operating power of the crusher for crushing traditional Chinese medicine waste is multiplied by the crushing time of the crusher in the current monitoring period to obtain the total energy consumption of the crusher in the current monitoring period, and the total energy consumption of the crusher in the current monitoring period is divided by the weight of qualified traditional Chinese medicine waste screened out after screening, so as to obtain the crushing energy consumption-to-mass ratio of traditional Chinese medicine waste in the current monitoring period.

[0020] Based on the weighted proportional coefficients stored in the database, the proportional relationship between the defined screen blockage rate and the screen blockage rate, the proportional relationship between the proportion of qualified waste and its corresponding defined value, and the proportional relationship between the defined crushing energy consumption mass ratio and the crushing energy consumption mass ratio are quantified respectively, and then the degree of effect of each proportional relationship on the pretreatment quality index of traditional Chinese medicine waste is evaluated. By summarizing the various degrees of effect, the pretreatment quality index of traditional Chinese medicine waste is obtained.

[0021] The pretreatment quality index of traditional Chinese medicine waste is used to evaluate the quality control efficiency of the pretreatment process of traditional Chinese medicine waste. The specific expression is: ; Wherein, PEI is the pretreatment quality index of traditional Chinese medicine waste, PA is the screen blockage rate of traditional Chinese medicine waste during the monitoring period, PW is the proportion of standard-compliant waste of traditional Chinese medicine waste during the monitoring period, PR is the crushing energy consumption mass ratio of traditional Chinese medicine waste during the monitoring period, P_PA is the defined screen blockage rate preset in the database, P_PW is the defined standard-compliant waste proportion preset in the database, P_PR is the defined crushing energy consumption mass ratio preset in the database, pa1 is the weighted proportional coefficient of the screen blockage rate preset in the database, pa2 is the weighted proportional coefficient of the standard-compliant waste proportion preset in the database, and pa3 is the weighted proportional coefficient of the crushing energy consumption mass ratio preset in the database.

[0022] The screen clogging rate is defined to indicate the maximum allowable proportion of screen pores blocked by Chinese medicine waste materials during the pretreatment of Chinese medicine waste; the proportion of qualified waste is defined to indicate the minimum proportion of the weight of qualified Chinese medicine waste after pretreatment to the total treatment volume; the crushing energy consumption mass ratio is defined to indicate the maximum allowable energy consumption per unit of qualified product.

[0023] The higher the screen blockage rate, the worse the effective permeability of the screen during the screening process, which will affect the screening efficiency and energy consumption of the screening process. The proportion of qualified waste of traditional Chinese medicine waste may decrease due to excessive particle size or uneven distribution, and the non-qualified materials need to be crushed for the second time, resulting in increased energy consumption during the crushing process and a significant increase in the crushing energy consumption-to-mass ratio. The lower the screen blockage rate, the higher the proportion of qualified waste, the more uniform the particle size of the material in the crushing process and the more it meets the requirements, which means that the pretreatment crushing process is stable, which can reduce the number of rework times and energy waste in the pretreatment of traditional Chinese medicine waste, indirectly reduce the energy consumption per unit of qualified product, and the crushing energy consumption-to-mass ratio decreases significantly. The screen blockage rate and the crushing energy consumption-to-mass ratio are negatively correlated with the pretreatment quality index of traditional Chinese medicine waste, and the proportion of qualified waste is positively correlated with the pretreatment quality index of traditional Chinese medicine waste.

[0024] Weighted proportional coefficient of screen blockage rate: used to quantify the effect of the proportional relationship between the screen blockage rate and the screen blockage rate on the pretreatment quality index of traditional Chinese medicine waste; weighted proportional coefficient of the proportion of qualified waste: used to quantify the effect of the proportional relationship between the proportion of qualified waste and the defined proportion of qualified waste on the pretreatment quality index of traditional Chinese medicine waste; weighted proportional coefficient of crushing energy consumption mass ratio: used to quantify the effect of the proportional relationship between the crushing energy consumption mass ratio and the crushing energy consumption mass ratio on the pretreatment quality index of traditional Chinese medicine waste; the value range of the three types of weighted proportional coefficients is 0 to 1, and the mapping relationship between the screen blockage rate, the proportion of qualified waste and the crushing energy consumption mass ratio and their corresponding weighted proportional coefficients is pre-stored in the database. Specifically, when the screen blockage rate, the proportion of qualified waste and the crushing energy consumption mass ratio are input, the database can directly retrieve and output the corresponding weighted proportional coefficient.

[0025] Specifically, it is determined whether to adjust the pretreatment process parameters of traditional Chinese medicine waste. The specific determination process is: within 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, then it is determined that the pretreatment process parameters of traditional Chinese medicine waste are not 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, then it is determined that the pretreatment process parameters of traditional Chinese medicine waste are adjusted, and based on the deviation value between the pretreatment quality index of traditional Chinese medicine waste and the pretreatment quality threshold, the crushing time of the crushing processor and the screening time of the screening processor in the next monitoring period are adjusted. The pretreatment quality threshold refers to the minimum value of the pretreatment quality index of traditional Chinese medicine waste.

[0026] Furthermore, the weight of the traditional Chinese medicine waste remaining after screening treatment in the current monitoring period is obtained. If the weight of the traditional Chinese medicine waste remaining after screening treatment in the current monitoring period is greater than or equal to the defined pretreatment weight, it indicates that the traditional Chinese medicine waste remaining after screening treatment of the current batch needs to be pretreated. The defined pretreatment weight refers to the maximum weight of the traditional Chinese medicine waste treated during the pretreatment process. The traditional Chinese medicine waste remaining after screening treatment is marked as the traditional Chinese medicine waste pretreatment object in the next monitoring period; if the weight of the traditional Chinese medicine waste remaining after screening treatment in the current monitoring period is less than the defined pretreatment weight, it indicates that the traditional Chinese medicine waste remaining after screening treatment of the current batch does not need to be pretreated. The pretreatment of the current batch of traditional Chinese medicine waste is terminated, and the traditional Chinese medicine waste remaining after screening treatment in the current monitoring period is mixed with the next batch of traditional Chinese medicine waste, and the traditional Chinese medicine waste remaining after screening treatment and the next batch of traditional Chinese medicine waste are marked as the traditional Chinese medicine waste pretreatment objects in the next monitoring period. Example; If the object of pretreatment of traditional Chinese medicine waste in the next monitoring cycle is the traditional Chinese medicine waste remaining after screening treatment and the pretreatment quality index of traditional Chinese medicine waste is less than the pretreatment quality threshold, then the crushing time of the crushing processor and the sieving time of the sieving processor in the next monitoring cycle will be reduced to avoid excessive pretreatment, reduce the energy consumption and loss of equipment during pretreatment, reserve time for the pretreatment of the next batch of traditional Chinese medicine waste, and avoid idle resources due to fixed long time consumption; If the object of pretreatment of traditional Chinese medicine waste in the next monitoring cycle is the traditional Chinese medicine waste remaining after screening treatment and the next batch of traditional Chinese medicine waste and the pretreatment quality index of traditional Chinese medicine waste is less than the pretreatment quality threshold, then the crushing time of the crushing processor and the sieving time of the sieving processor in the next monitoring cycle will be increased. Extending the pretreatment time can make the traditional Chinese medicine waste more fully crushed and screened more thoroughly. Increasing the time can complete high-quality pretreatment and avoid waste of resources due to incomplete pretreatment.

[0027] As mentioned above, the crushing time of the crushing machine and the screening time of the screening machine in the next monitoring period are adjusted. The specific adjustment process is: the difference between the pretreatment quality threshold and the pretreatment quality index of the traditional Chinese medicine waste is processed in absolute value, and the absolute difference is divided by the pretreatment quality threshold to obtain the deviation value of the pretreatment quality index of the traditional Chinese medicine waste and the pretreatment quality threshold; the database stores the deviation value of the pretreatment quality index of the traditional Chinese medicine waste and the pretreatment quality threshold and the crushing time change value of the next monitoring period. The deviation value of the pretreatment quality index of the traditional Chinese medicine waste and the pretreatment quality threshold is input into the database to obtain the crushing time change value of the next monitoring period. If the crushing time of the next monitoring period is increased, the basic crushing time of the next monitoring period is added to the crushing time change value of the next monitoring period to obtain the basic crushing time of the next monitoring period; if the crushing time of the next monitoring period is increased, the basic crushing time of the next monitoring period is added to the crushing time change value of the next monitoring period to obtain the basic crushing time of the next monitoring period; If the crushing time of the next monitoring cycle is reduced, the basic crushing time of the next monitoring cycle is subtracted from the change in crushing time of the next monitoring cycle to obtain the basic crushing time of the next monitoring cycle; the database stores a mapping table of the deviation value of the pretreatment quality index of traditional Chinese medicine waste and the pretreatment quality threshold and the change in screening time of the next monitoring cycle. The deviation value of the pretreatment quality index of traditional Chinese medicine waste and the pretreatment quality threshold is input into the database to obtain the change in screening time of the next monitoring cycle. If the screening time of the next monitoring cycle is increased, the basic screening time of the next monitoring cycle is added to the change in screening time of the next monitoring cycle to obtain the basic screening time of the next monitoring cycle; if the screening time of the next monitoring cycle is reduced, the basic screening time of the next monitoring cycle is subtracted from the change in screening time of the next monitoring cycle to obtain the basic screening time of the next monitoring cycle.

[0028] The present invention realizes dynamic optimization of the pretreatment process through the pretreatment quality index, adjusts the crushing and screening time according to the deviation value between the pretreatment quality index of traditional Chinese medicine waste and the pretreatment quality threshold within the monitoring period, avoids the problem of insufficient material adaptability caused by fixed parameters in traditional Chinese medicine waste pretreatment, implements a graded treatment mechanism for pretreatment residual materials, improves material utilization, reduces waste, and significantly improves the stability and economy of the traditional Chinese medicine waste pretreatment link.

[0029] Update the pretreatment process parameters of traditional Chinese medicine waste, and pretreat the traditional Chinese medicine waste pretreatment objects in the next monitoring cycle; after the pretreatment of the current batch of traditional Chinese medicine waste is completed, obtain the total number of pretreatments of the current batch of traditional Chinese medicine waste; if the total number of pretreatments of the current batch of traditional Chinese medicine waste is less than or equal to the pretreatment number threshold, it means that the pretreatment process parameters of the current batch of traditional Chinese medicine waste are reasonably set, and the pretreatment number threshold refers to the maximum number of pretreatments of traditional Chinese medicine waste, then analyze the total pretreatment quality index of the current batch of traditional Chinese medicine waste. The above-mentioned total pretreatment quality index of the current batch of traditional Chinese medicine waste is based on the pretreatment quality index of traditional Chinese medicine waste in each monitoring cycle. The quality index of Chinese medicinal waste pretreatment is obtained by accumulating the quality index of Chinese medicinal waste pretreatment in each monitoring period, and dividing the accumulated result by the total number of pretreatment times of the current batch of Chinese medicinal waste to obtain the total pretreatment quality index of the current batch of Chinese medicinal waste; if the total number of pretreatment times of the current batch of Chinese medicinal waste is greater than the pretreatment times threshold, an early warning will be issued for the pretreatment process of the current batch of Chinese medicinal waste; it will be prompted that the process parameters of the current batch of Chinese medicinal waste pretreatment are not adaptable enough, which may lead to excessive processing of materials, and the process parameters of the current batch of Chinese medicinal waste pretreatment and the material characteristics of Chinese medicinal waste will be checked, and the threshold of the pretreatment parameters will be recalibrated to avoid invalid cycle processing.

[0030] Specifically, the TCM waste is composted, and the specific processing process is: based on the weight of the TCM waste after pretreatment, the weight of biochar, the volume of microbial agents and the weight of enzyme agents that should be added to the TCM waste are matched in the database; a mapping table between the weight of TCM waste and the weight of biochar added during the composting process is stored in the database, and the weight of biochar added during the composting process can be obtained by inputting the weight of TCM waste in the database; a mapping table between the weight of TCM waste and the volume of microbial agents added during the composting process is stored in the database, and the volume of microbial agents added during the composting process can be obtained by inputting the weight of TCM waste in the database; a mapping table between the weight of TCM waste and the weight of enzyme agents added during the composting process is stored in the database, and the volume of microbial agents added during the composting process can be obtained by inputting the weight of TCM waste in the database; a mapping table between the weight of TCM waste and the weight of enzyme agents added during the composting process is stored in the database, and the weight of The weight of the enzyme added during the composting process can be obtained by inputting the weight of the traditional Chinese medicine waste into the database; biochar, microbial agents and enzymes are added to the pretreated traditional Chinese medicine waste, the compost mixture is stirred, and pure water is added to control the water content of the compost mixture to the water content threshold. The water content threshold is the minimum water content in the composting process. By adding a certain proportion of pure water to the compost mixture multiple times, the purpose of controlling the water content of the compost mixture to the water content threshold is achieved. Before adding pure water, the water content in the compost mixture is collected. Based on the current weight of the compost mixture, the difference between the water content threshold and the current water content is multiplied by the weight of the current compost mixture, and the product is divided by 1 minus the difference between the water content threshold to obtain the amount of pure water added.

[0031] Figure 3 This is a schematic diagram of the pretreatment process of traditional Chinese medicine waste provided by an embodiment of the present invention. By collecting traditional Chinese medicine waste, based on the initial moisture content of the current batch of traditional Chinese medicine waste, the basic drying time within the monitoring period is adjusted, and the traditional Chinese medicine waste is pretreated. After the pretreatment is completed, the treatment results of the traditional Chinese medicine waste are analyzed, and the quality index is calculated based on the pretreatment quality parameters to determine whether the pretreatment process parameters of the traditional Chinese medicine waste are adjusted. After the pretreatment of the traditional Chinese medicine waste is completed, the traditional Chinese medicine waste is composted.

[0032] Furthermore, the composting process parameters of each monitoring area of ​​traditional Chinese medicine waste are monitored. The specific analysis process is as follows: different monitoring areas for traditional Chinese medicine waste are set, and after the basic composting time, the composting process parameters of each monitoring area of ​​traditional Chinese medicine waste are collected during the composting monitoring period, including water content, pH value and salt concentration; it is determined whether the composting process parameters of each monitoring area during the composting monitoring period meet the first condition. If a monitoring area meets the first condition during the composting monitoring period, it means that the composting process parameters of the area during the composting monitoring period are within the safe range, and the monitoring area is marked as a monitoring area with qualified process parameters; if a monitoring area does not meet the first condition during the composting monitoring period, it means that the composting process parameters of the area during the composting monitoring period are not within the safe range. If it is within the safe range, the monitoring area will be marked as a process parameter abnormal monitoring area; the qualified monitoring areas of each process parameter are counted and continuously monitored to determine whether the composting process parameters of each composting monitoring area of ​​traditional Chinese medicine waste are valid; the first condition refers to that the moisture content of the monitoring area during the composting monitoring period is less than the upper limit of the defined moisture content interval and greater than the lower limit of the defined moisture content interval, the pH value is less than the upper limit of the defined pH value interval and greater than the lower limit of the defined pH value interval, and the salt concentration is less than or equal to the salt concentration threshold; the moisture content interval represents the target range of moisture content during the composting process, the pH value interval represents the target range of pH value during the composting process, and the salt concentration threshold represents the maximum value allowed for salt concentration during the composting process.

[0033] The above-mentioned setting of different monitoring areas for Chinese medicine waste refers to setting different monitoring areas from the spatial dimension of the pile body, and dividing the vertical direction into three layers according to the height of the pile body. The upper layer is the area extending downward from the surface of the Chinese medicine waste pile body to one-third of the height of the pile body. The upper layer is the surface layer of the pile body in direct contact with the external environment, which is significantly affected by atmospheric temperature and air flow disturbances, and is 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 surface of the compost; the middle layer is the area extending downward from one-third of the height of the Chinese medicine waste pile body to one-third of the height of the compost body. The middle layer is the core reaction area of ​​the pile, where the material density is moderate, the heat generated by microbial activity is not easy to diffuse quickly, the temperature stability is strong, and the distribution of moisture and oxygen is relatively balanced. The monitoring points in the middle layer can reflect the mainstream state of the compost degradation process; the lower layer is an area that starts from two-thirds of the height of the traditional Chinese medicine waste pile and extends downward to one-third of the height. The lower layer is affected by gravity, and leachate is easy to accumulate in this area. The humidity is high and oxygen penetration is difficult. The monitoring points in the lower layer can capture the material migration and environmental change characteristics deep in the pile; the horizontal The pile is divided into nine monitoring points along its length and width. Along the length of the pile, the system divides the pile into three equal parts at intervals of one-third of its length, forming two longitudinal dividing lines. Along the width of the pile, the system divides the pile into three equal parts at intervals of one-third of its width, forming two transverse dividing lines. The two longitudinal dividing lines intersect with the two transverse dividing lines, dividing the pile plane into nine grid areas of equal area. The central grid monitoring point, located at the geometric center of the pile plane, reflects the core parameters of the area with the densest materials and the most active microbial activity. The four corner grid monitoring points are located near the corners of the pile, focusing on monitoring the boundary areas in contact with the external environment and capturing the edge effects of temperature and humidity. The four middle grid monitoring points are distributed along the midlines of the length and width of the pile, reflecting the parameter changes in the transition zone between the edge and the center of the pile. The three-layer vertical division accurately corresponds to the environmental gradient from the surface to the depth of the pile, and the nine-square grid points in the horizontal direction fully cover the core and edge areas of the plane area. This equalized spatial coverage ensures the representativeness of the monitoring data, effectively capturing the parameter differences at different locations in the pile, and providing sample data for subsequent composting process analysis.

[0034] Specifically, it is determined whether the composting process parameters of each composting monitoring area to which traditional Chinese medicine waste belongs are valid. The specific determination process is: obtaining the process parameter qualified time of each process parameter qualified monitoring area, the process parameter qualified time refers to the continuous time that each composting process parameter meets the first condition, if the process parameter qualified time of a process parameter qualified monitoring area is greater than the process parameter qualified time threshold, indicating that the composting process parameter has reached the target stable time, then the process parameter qualified monitoring area is marked as a valid composting area, and the compost quality of the valid composting monitoring area is counted and evaluated; if the process parameter qualified time of a process parameter qualified monitoring area is less than or equal to the process parameter qualified time threshold, indicating that the composting process parameter has not yet reached the target stable time, then the process parameter qualified monitoring area is continuously monitored until the composting of traditional Chinese medicine waste is completed. The above-mentioned process parameter qualified time threshold represents the minimum value of the process parameter qualified time; the statistics and monitoring of each process parameter qualified monitoring area can distinguish the effective composting area, reduce the subsequent redundant manpower investment, and avoid waste of resources in compost quality assessment caused by failure of composting process parameters by timely determining the effectiveness of composting process parameters.

[0035] Figure 4 This is a schematic diagram of a composting process monitoring and effective compost determination process provided by an embodiment of the present invention. Different monitoring areas for traditional Chinese medicine waste are set. After a basic composting time, composting process parameters of each monitoring area of ​​the traditional Chinese medicine waste are collected within the composting monitoring period. By judging whether the composting process parameters meet a first condition, each monitoring area is divided into a process parameter qualified monitoring area and a process parameter abnormality monitoring area. The process parameter qualified time of the process parameter qualified monitoring area is counted. By judging whether the qualified time of the process parameter qualified monitoring area is greater than a threshold, the process parameter qualified monitoring area with a process parameter qualified time greater than the threshold is marked as an effective composting monitoring area, thereby screening out the effective composting monitoring area.

[0036] The present invention improves the controllability of the composting process by regionalizing the composting of traditional Chinese medicine waste and determining the effective composting areas. By determining the intervals of various composting process parameters and counting the qualified time of the process parameters, the effective composting areas are accurately identified, thereby avoiding the problem of local anomalies being masked in the overall monitoring of traditional Chinese medicine waste composting. The setting of defining the number of effective composting areas further ensures the representativeness of the compost quality assessment results, and provides a reliable data basis for subsequent compost quality assessment.

[0037] Specifically, the compost quality of each effective compost monitoring area is evaluated. The specific analysis process is: collecting compost quality evaluation data of traditional Chinese medicine waste in the effective compost monitoring area, where the compost quality evaluation data includes: urease activity in the effective compost monitoring area, acid phosphatase activity in the effective compost monitoring area, and cabbage seed germination rate in the effective compost monitoring area.

[0038] Urease activity refers to the ability of urease in the compost materials in the effective compost monitoring area to catalyze the decomposition of urea into ammonia and carbon dioxide. The compost samples in the effective compost monitoring area are made into an extract, urea substrate is added and the mixture is reacted in a constant temperature water bath for a certain period of time. The ammonia content generated by the reaction is measured to obtain the urease activity. The reaction time is determined by relevant personnel in this field. Acid phosphatase activity refers to the ability of acid phosphatase in the compost materials in the effective compost monitoring area to catalyze the hydrolysis of organophosphorus compounds into inorganic phosphorus. The compost samples in the effective compost monitoring area are reacted with disodium phenyl phosphate solution under acidic conditions to measure the ammonia content per unit mass of the sample. The amount of inorganic phosphorus released by the product is used to derive the acid phosphatase activity; the cabbage seed germination rate refers to the germination ratio of cabbage seeds in the compost extract in the effective compost monitoring area, which reflects the maturity and biosafety of the compost. Compost samples are taken from the effective compost monitoring area and mixed with pure water in a set ratio to prepare an extract. Cabbage seeds are placed on filter paper soaked in the extract and cultured at a set temperature and set light intensity for 72 hours. The ratio 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 this field.

[0039] The proportional weighting coefficients preset in the database were used to quantify the degree of influence of the proportional relationships between the three types of parameters and the corresponding defined values ​​on the compost quality assessment index of the effective composting monitoring area. Specifically, the proportional relationship between urease activity and the defined urease activity, the proportional relationship between acid phosphatase activity and the defined acid phosphatase activity, and the proportional relationship between cabbage seed germination rate and the defined cabbage seed germination rate were assigned corresponding proportional weights and summarized to obtain the compost quality assessment index of the effective composting monitoring area.

[0040] The compost quality evaluation index of 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: ; Where TEI is the compost quality evaluation 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 cabbage seed germination rate of the effective compost monitoring area, T_TU is the defined urease activity preset in the database, T_TA is the defined acid phosphatase activity preset in the database, T_TG is the defined cabbage seed germination rate preset in the database, ta1 is the urease activity ratio weighting coefficient preset in the database, ta2 is the acid phosphatase activity ratio weighting coefficient preset in the database, and ta3 is the cabbage seed germination rate ratio weighting coefficient preset in the database.

[0041] The definition of urease activity is the minimum benchmark value that urease activity must reach during the composting process. The definition of acid phosphatase activity is the minimum activity level that unit mass of compost can hydrolyze organic phosphorus to produce inorganic phosphorus per hour. The definition of cabbage seed germination rate is based on the minimum requirement for normal germination rate of compost extract under set culture conditions.

[0042] The higher the urease activity, the stronger the ability of microorganisms in the compost of traditional Chinese medicine waste to decompose and metabolize nitrogen-containing organic matter, and the more complete the nitrogen release, which is beneficial for the subsequent waste to provide nitrogen nutrition as fertilizer. The higher the acid phosphatase activity, the higher the conversion efficiency of organic phosphorus to available phosphorus in the compost of traditional Chinese medicine waste, which can provide more absorbable phosphorus nutrition for crops. The compost of traditional Chinese medicine waste is also more fully decomposed, and the harmful substances are more thoroughly decomposed, and the germination rate of cabbage seeds also increases accordingly. The higher the cabbage seed germination rate, the lower the content of harmful substances in the compost of traditional Chinese medicine waste, and the weaker the inhibitory effect of compost on crop growth; the lower the cabbage seed germination rate, the presence of toxic substances in the compost of traditional Chinese medicine waste, which will inhibit the activity of microorganisms, thereby leading to a decrease in the enzyme activity 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 in the effective compost monitoring area.

[0043] Urease activity proportional weighting coefficient: used to quantify the influence of the proportional relationship between the urease activity in the effective compost monitoring area and its defined value on the compost quality assessment index of the effective compost monitoring area; acid phosphatase activity proportional weighting coefficient: used to quantify the influence of the proportional relationship between the acid phosphatase activity in the effective compost monitoring area and its defined value on the compost quality assessment index of the effective compost monitoring area; cabbage seed germination rate proportional weighting coefficient: used to quantify the influence of the proportional relationship between the cabbage seed germination rate in the effective compost monitoring area and its defined value on the compost quality assessment index of the effective compost monitoring area; the value range of the three types of proportional weighting coefficients is 0 to 1, and the database pre-stores the mapping relationship between urease activity, acid phosphatase activity and cabbage seed germination rate and their corresponding proportional weighting coefficients. Specifically, when urease activity, acid phosphatase activity and cabbage seed germination rate are input, the database can directly retrieve and output the corresponding proportional weighting coefficient.

[0044] Based on the total pretreatment quality index of the current batch of traditional Chinese medicine waste, the corrected value of the compost quality assessment index of the traditional Chinese medicine waste stored in the database is obtained. The database stores a mapping table of the total pretreatment quality index of traditional Chinese medicine waste and the corrected value of the compost quality assessment index. The corrected value of the compost quality assessment index of traditional Chinese medicine waste can be obtained by inputting the total pretreatment quality index of traditional Chinese medicine waste into the database; the compost quality assessment index of each effective compost monitoring area is accumulated, the accumulated result is divided by the number of effective compost monitoring areas, and multiplied by the corrected value of the compost quality assessment index of traditional Chinese medicine waste, so as to obtain the compost quality assessment index of traditional Chinese medicine waste. The compost quality assessment index of traditional Chinese medicine waste is used to characterize the compost quality of traditional Chinese medicine waste.

[0045] Specifically, it is determined whether to adjust the pretreatment process of traditional Chinese medicine waste. The specific determination process is: after the composting of traditional Chinese medicine waste is completed, if the number of effective composting monitoring areas is less than the defined number of effective composting areas, and the defined number of effective composting areas refers to the minimum number of effective composting areas, then the current batch of traditional Chinese medicine waste compost is marked as invalid compost, 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 traditional Chinese medicine waste compost is marked as effective compost, and the compost quality evaluation index of traditional Chinese medicine waste is obtained. If the compost quality evaluation index of traditional Chinese medicine waste is greater than or equal to the compost quality evaluation index threshold, it means that the compost is good. If it is determined that the compost quality of the current batch of traditional Chinese medicine waste reaches the expected compost quality, the basic drying time, basic crushing time, and basic screening time in the pretreatment process parameters of the current batch of traditional Chinese medicine waste are recorded in the database; if the compost quality assessment index of the traditional Chinese medicine waste is less than the compost quality assessment index threshold, it means that the compost quality of the current batch of traditional Chinese medicine waste does not reach the expected compost quality, then based on the deviation value between the compost quality assessment index of the traditional Chinese medicine waste and the compost quality assessment index threshold, the basic drying time, basic crushing time, and basic screening time in the pretreatment process parameters of the next batch of traditional Chinese medicine waste are increased and adjusted, and the adjusted pretreatment process parameters of the traditional Chinese medicine waste are recorded in the database.

[0046] Furthermore, early warnings are issued for differences in compost monitoring areas. The specific warning content is: a notification of significant quality differences in the current batch of traditional Chinese medicine waste compost is sent to the management end, the pretreatment of the next batch of compost is suspended, the parameters of each monitoring area are checked to analyze the reasons for abnormal compost quality, and the division standards of each monitoring area and the pretreatment process parameter adjustment strategy are recalibrated to avoid the continued expansion of differences affecting the subsequent traditional Chinese medicine waste composting effect.

[0047] As mentioned above, the compost quality assessment index threshold refers to the minimum value of the compost quality assessment index of traditional Chinese medicine waste; the difference between the compost quality assessment index threshold and the compost quality assessment index of traditional Chinese medicine waste is divided by the compost quality assessment index threshold to obtain the deviation value between the compost quality assessment index of traditional Chinese medicine waste and the compost quality assessment index threshold; the database stores the deviation value of the compost quality assessment index and the compost quality assessment index threshold and the basic drying time increase mapping table, and the basic drying time increase can be obtained by inputting the deviation value of the compost quality assessment index and the compost quality assessment index threshold in the database, and the basic drying time increase can be obtained, and the basic drying time in the pretreatment process parameters of the next batch of traditional Chinese medicine waste is obtained, and the basic drying time in the pretreatment process parameters of the next batch of traditional Chinese medicine waste is added to the basic drying time increase, so as to obtain the basic drying time in the pretreatment process parameters of the next batch of traditional Chinese medicine waste after adjustment; the database stores the deviation value of the compost quality assessment index and the compost quality assessment index threshold and the basic crushing time increase mapping table, and the compost quality assessment index and compost quality are input in the database. The deviation value of the compost quality assessment index threshold can be used to obtain the increase in basic crushing time, obtain the basic crushing time in the pretreatment process parameters of the next batch of traditional Chinese medicine waste, and add the basic crushing time increase to the basic crushing time in the pretreatment process parameters of the next batch of traditional Chinese medicine waste, so as to obtain the basic crushing time in the pretreatment process parameters of the next batch of traditional Chinese medicine waste after increase and adjustment; the database stores a mapping table of the deviation value of the compost quality assessment index and the compost quality assessment index threshold and the basic screening time increase, and the deviation value of the compost quality assessment index and the compost quality assessment index threshold is input into the database to obtain the basic screening time increase, obtain the basic screening time in the pretreatment process parameters of the next batch of traditional Chinese medicine waste, and add the basic screening time increase to the basic screening time in the pretreatment process parameters of the next batch of traditional Chinese medicine waste, so as to obtain the basic screening time in the pretreatment process parameters of the next batch of traditional Chinese medicine waste after increase and adjustment; thereby realizing the increase and adjustment of the basic drying time, basic crushing time, and basic screening time in the pretreatment process parameters of the next batch of traditional Chinese medicine waste.

[0048] As mentioned above, by comparing the compost quality assessment index of traditional Chinese medicine waste with the compost quality assessment index threshold, closed-loop feedback adjustment of the parameters of the pretreatment process of traditional Chinese medicine waste is realized, which can make up for the deficiencies of the current parameters in a targeted manner, quickly correct the deviation of the pretreatment process parameters, and reduce the risk of substandard compost quality of consecutive batches of traditional Chinese medicine waste; by recording the effective parameters in the database, the data samples are increased, and the optimal pretreatment parameters corresponding to different batches of traditional Chinese medicine waste can be extracted from the database, so that the pretreatment parameters fit the material characteristics and composting requirements of traditional Chinese medicine waste, and gradually improve 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, which reduces the cost of invalid parameter trial and error, and reduces the energy waste caused by repeated adjustment of equipment parameters, which not only ensures the real-time control of compost quality, but also promotes the long-term optimization of pretreatment parameters, and realizes the coordinated improvement of compost quality stability, parameter adaptability and system economy.

[0049] Figure 5 The present invention provides a flow chart of compost quality assessment and pretreatment parameter optimization, which collects compost quality assessment data of Chinese medicine waste in an effective compost monitoring area, calculates a compost quality assessment index of the effective compost monitoring area, obtains a compost quality assessment index correction value of the Chinese medicine waste stored in a database, and corrects the compost quality assessment index of the Chinese medicine waste to obtain a compost quality assessment index of the Chinese medicine waste. If the compost quality assessment index of the Chinese medicine waste is greater than or equal to a compost quality assessment index threshold, the pretreatment process parameters of the current batch of Chinese medicine waste are included in the database; if the compost quality assessment index of the Chinese medicine waste is less than the compost quality assessment index threshold, the pretreatment process parameters of the next batch of Chinese medicine waste are adjusted, and the adjusted pretreatment process parameters of the Chinese medicine waste are included in the database.

[0050] The present invention achieves continuous improvement in the quality of Chinese medicine waste composting through the linked optimization of the compost quality evaluation 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 associates the compost quality and pretreatment process through correction values; when the evaluation 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, solving the problem of disconnection between pretreatment and final quality in traditional Chinese medicine waste composting, and gradually improving the maturity and stability of the compost through continuous optimization of parameter accumulation.

[0051] The present invention provides a method and system for evaluating the compost quality of traditional Chinese medicine waste. By constructing a closed-loop system for dynamic adjustment of traditional Chinese medicine waste pretreatment parameters, multi-dimensional monitoring of the composting process and compost quality evaluation, in the traditional Chinese medicine waste pretreatment stage, the total pretreatment efficiency index in the traditional Chinese medicine waste pretreatment process is quantified by the pretreatment quality index; in the composting stage, the effective composting area is identified by real-time monitoring of the composting process parameters; in the quality evaluation stage, the compost quality evaluation index is corrected by combining the urease activity, acid phosphatase activity and seed germination rate biological indicators with the total pretreatment quality index of the traditional Chinese medicine waste, and the pretreatment quality, composting process parameters and final compost quality are correlated, thereby solving the problems of data fragmentation and regulation lag in each link in traditional evaluation. The system integrates pretreatment, composting monitoring and compost quality evaluation through modular design, reduces manual intervention errors, and improves the efficiency and reliability of compost quality evaluation.
