[0050] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0051] Example:

[0052] Please see the appendix Figure 1 -Appendix Figure 2 This invention provides a method for recycling and treating waste from beef cattle slaughtering and processing, comprising the following steps:

[0053] S1. Collect waste generated from beef cattle slaughtering and processing in a classified manner;

[0054] S2. Pre-treat the collected waste;

[0055] S3. The pre-treated waste is processed through a resource recovery unit to obtain usable resources;

[0056] S4. Construct a waste treatment parameter optimization model, and optimize the parameters in the treatment process based on the data from the classification, collection, pretreatment and resource recovery processes.

[0057] S5. Recycle available resources.

[0058] Specifically, S1, sorting and collection, is fundamental. Different forms of waste have vastly different properties and require drastically different subsequent treatments; sorting avoids interference from mixed processing. S2, pretreatment, prepares for resource recovery by removing impurities and adjusting the physical form of the waste to better suit subsequent processing techniques. S3, resource recovery, transforms waste into usable resources, turning "waste" into "treasure." S4, constructing a waste treatment parameter optimization model, dynamically optimizes parameters based on full-process data to ensure efficient operation at each stage. S5, recycling, reinvests the treated resources in production or environmental applications, achieving sustainable resource utilization. Through a systematic and process-oriented design, the fragmented and inefficient nature of traditional treatment methods is avoided, significantly improving waste treatment efficiency and resource recovery rates, reducing treatment costs, and minimizing environmental pollution caused by waste.

[0059] The steps for constructing the waste treatment parameter optimization model include:

[0060] The data on waste weight and composition ratio during the sorting and collection stage, energy consumption and efficiency during the pretreatment stage, and resource output from the resource recovery unit are normalized. The calculation formula is as follows:

[0061]

[0062] in, For normalized data, This is the original data. and These are the maximum and minimum values ​​in the original data, respectively.

[0063] The grey relational analysis algorithm is used to calculate the correlation degree between different processing parameters and resource output and processing energy consumption. The correlation degree calculation formula is as follows:

[0064]

[0065] in, For the first The processing parameters and reference sequence in the first... The degree of correlation at any given moment As a reference sequence, For comparing sequences, To distinguish;

[0066] Based on the correlation results, a waste treatment parameter optimization model is constructed by combining genetic algorithms to iteratively optimize parameters such as temperature, pressure, and treatment time during the treatment process.

[0067] Specifically, data normalization aims to eliminate differences in the dimensions and numerical ranges of different data indicators, making various data comparable and providing an accurate foundation for subsequent analysis. Grey relational analysis algorithms determine the degree of correlation between factors based on the similarity of the geometric shapes of data sequence curves. By calculating the correlation between different processing parameters and resource output and processing energy consumption, it can identify which parameters have a greater impact on key indicators. Genetic algorithms iteratively optimize parameters such as temperature, pressure, and processing time during the processing through selection, crossover, and mutation operations, gradually approaching the optimal solution. The waste treatment parameter optimization model built upon this foundation can adjust parameters in real time and accurately according to waste characteristics and processing needs, effectively avoiding the inefficiencies and resource waste caused by traditional empirical parameter settings. This ensures the entire processing process remains highly efficient and energy-saving, significantly improving the overall benefits of waste recycling.

[0068] The classified collection of waste generated from beef cattle slaughtering and processing includes:

[0069] Waste is classified into solid waste, liquid waste, and gaseous waste;

[0070] Solid waste, liquid waste, and gaseous waste are collected separately using different collection devices.

[0071] Specifically, waste is categorized into solid, liquid, and gaseous states based on their physical properties and the differences in subsequent processing technologies. Solid waste, such as bones and fur, is suitable for physical processing such as crushing and dehydration; liquid waste, such as blood and grease mixtures, requires separation technology to extract useful components; and gaseous waste, such as odorous gases, requires purification treatment. Using different collection devices prevents waste from mixing and contaminating each other during collection, while also facilitating targeted subsequent processing. This categorized collection method ensures the efficiency and professionalism of waste treatment from the source, reduces the complex separation process caused by mixing, and lowers the difficulty and cost of treatment.

[0072] The pretreatment of the collected waste includes:

[0073] Solid waste is crushed and dehydrated.

[0074] Solid-liquid separation treatment of liquid waste;

[0075] Dust and odor removal treatments are performed on gaseous waste.

[0076] Specifically, pulverizing solid waste reduces its volume, increases the contact area with subsequent treatment media, and improves processing efficiency; dehydration reduces moisture content, lowering transportation costs and subsequent energy consumption; solid-liquid separation of liquid waste removes solid impurities, facilitating subsequent refining of liquid components; dust removal of gaseous waste removes particulate matter, preventing clogging of subsequent purification equipment; and deodorization removes harmful or odorous gaseous components through adsorption, chemical reactions, and other methods. The treated waste better meets the requirements of subsequent processes; for example, pulverized solid waste decomposes more quickly during fermentation, liquid waste after solid-liquid separation is easier to extract useful components from, and purified gaseous waste meets emission standards.

[0077] The formula for calculating the particle size during the solid waste pulverization process is as follows:

[0078]

[0079] in, For particle size, This represents the total volume of solid waste. This refers to the number of particles after crushing. This represents the average surface area of ​​a single particle.

[0080] Specifically, the particle size control method based on quantitative calculation changes the traditional practice of controlling the degree of crushing based on experience. It can ensure that solid waste is fully reacted in subsequent resource recovery treatment, improve resource conversion rate, such as increasing biogas production during fermentation; and avoid energy waste and equipment wear caused by over-crushing, reduce treatment costs, and improve the stability and repeatability of the treatment process.

[0081] The liquid waste solid-liquid separation treatment adopts centrifugal separation method, and the centrifugal separation speed is calculated by the following formula:

[0082]

[0083] in, The centrifugal separation speed, It is the acceleration due to gravity. For centrifugal force, Where is the centrifugal radius, ω is the angular velocity.

[0084] Specifically, during centrifugation, the rotation speed directly affects the solid-liquid separation effect. If the rotation speed is too low, the solid-liquid separation will be incomplete; if the rotation speed is too high, it may lead to excessive equipment load, increased energy consumption, or even damage to the useful substances in the liquid components. By scientifically calculating the rotation speed using formulas, a balance between energy consumption and equipment performance can be achieved while ensuring the separation effect. This improves the efficiency and quality of solid-liquid separation of liquid waste, ensures that solid impurities are fully separated, and provides pure raw materials for subsequent refining of liquid components.

[0085] The resource recovery unit includes a fermentation unit, an extraction unit, and a purification unit;

[0086] The fermentation unit is used to ferment pretreated organic waste.

[0087] The refining unit is used to refine the useful components in the liquid waste;

[0088] The purification unit is used to purify gaseous waste.

[0089] Specifically, through the coordinated work of various parts of the resource-based treatment unit, high-value transformation of waste is achieved. The biogas produced by fermentation can replace fossil fuels, reducing enterprise energy costs and carbon emissions. The extracted useful components can be used as raw materials in industries such as chemicals and feed, creating economic value. The purified gaseous waste meets emission standards, protecting the atmospheric environment. This comprehensive resource-based treatment method greatly improves the utilization rate of waste.

[0090] The fermentation temperature control calculation formula during the fermentation process in the fermentation unit is as follows:

[0091]

[0092] in, This refers to the real-time temperature during the fermentation process. The initial temperature, The heat generated during the fermentation process. For the quality of fermentation materials, This refers to the specific heat capacity of the material.

[0093] Specifically, precise fermentation temperature control ensures the efficient and stable operation of the fermentation process. This significantly improves the yield and quality of biogas, enabling the fermentation unit to continuously and stably provide clean energy to the enterprise. At the same time, it avoids fermentation failure or inefficiency caused by improper temperature control, reduces raw material waste and processing time, and improves the reliability and economic benefits of the entire resource recovery process.

[0094] The recycling of available resources includes:

[0095] The biogas produced by fermentation will be used for energy supply;

[0096] The extracted useful components are used as raw materials in other production processes;

[0097] The purified gaseous waste will be discharged in compliance with standards.

[0098] Specifically, the biogas produced by fermentation is transported through pipelines to the energy demand side for use in heating and power generation in the plant area, serving as an effective supplement to the energy supply; the extracted useful components are further processed according to their properties and uses, and then used as raw materials in the production of food, chemicals, feed, etc.; the purified gaseous waste is discharged into the atmosphere through the emission system in compliance with standards, reducing environmental pollution.

[0099] A system for recycling beef cattle slaughtering and processing waste includes:

[0100] The sorting and collection module is used to sort and collect waste generated from beef cattle slaughtering and processing, classifying the waste into solid waste, liquid waste and gaseous waste, and collecting them separately through different collection devices;

[0101] The pretreatment module, connected to the sorting and collection module, is used to pretreat the collected waste, crush and dehydrate solid waste, separate liquid waste from solids, and remove dust and odor from gaseous waste.

[0102] The resource recovery module, connected to the pretreatment module, is used to process the pretreated waste through a fermentation unit, an extraction unit, and a purification unit to obtain usable resources.

[0103] The model building and parameter optimization module is used to build a waste treatment parameter optimization model. It normalizes the data in the process of classification collection, pretreatment and resource recovery, uses the grey relational analysis algorithm to calculate the correlation between different treatment parameters and resource output and treatment energy consumption, and combines the genetic algorithm to iteratively optimize the temperature, pressure and treatment time parameters in the treatment process.

[0104] The recycling module, connected to the resource recovery module, is used to recycle available resources, including using biogas produced by fermentation for energy supply, using extracted useful components as raw materials for other production processes, and ensuring that purified gaseous waste is discharged in compliance with standards.

[0105] Specifically, the model building and parameter optimization module continuously collects operational data from each module and establishes a dynamic feedback mechanism. When real-time parameters such as the current and rotation speed of the solid waste crushing equipment in the pretreatment module are monitored, the module combines the following formula:

[0106]

[0107] Compare the energy consumption per unit weight before and after parameter optimization. If the energy consumption reduction does not meet expectations, readjust parameters such as the motor power and blade speed of the crushing equipment until the energy consumption is reduced to the target range, achieving energy saving and efficiency improvement in the pretreatment stage. For a percentage reduction in energy consumption, Energy consumption per unit weight for solid waste pulverization before parameter optimization. The energy consumption per unit weight for solid waste pulverization after parameter optimization.

[0108] In the resource recovery module, the model building and parameter optimization module monitors data such as temperature, humidity, and microbial activity in the fermentation unit in real time, based on the formula:

[0109]

[0110] The energy conversion rate is dynamically evaluated. If a slow improvement in energy conversion rate is detected, parameters such as fermentation temperature and material addition ratio will be re-optimized using a genetic algorithm. For example, the fermentation temperature may be adjusted from... Adjust to Simultaneously, it alters the carbon-to-nitrogen ratio in the raw materials, thereby improving energy conversion efficiency and ensuring the efficient operation of resource-based treatment. For the percentage increase in energy conversion rate, The energy output per unit time of the fermentation unit after parameter optimization. To optimize the parameters, the energy output per unit time of the pre-fermentation unit was determined.
