Description

Technical Field

[0001] The invention relates to the technical field of organically contaminated soil remediation, and in particular to a transmission system for remediating organically contaminated soil based on solar heating-enhanced saturated zone. Background Art

[0002] The fluctuation of groundwater level is a natural process. The fluctuation of groundwater level can disturb the reducing environment underground. The disturbance process will lead to the introduction of oxygen, thus changing the original anaerobic conditions underground to an aerobic environment. Under aerobic conditions, Fe(II) minerals rich in the underground environment react with oxygen to generate highly oxidizing active oxygen species, such as hydroxyl radicals (•OH). Hydroxyl radicals (•OH) have extremely high reactivity and can effectively degrade organic pollutants in saturated reducing soils, which is useful for pollution remediation of underground environments.

[0003] However, the concentration of •OH produced by this disturbance process caused by the fluctuation of the saturated zone water level in the natural state is often low, resulting in unsatisfactory degradation efficiency of pollutants. In order to improve the generation efficiency of •OH, studies have found that through thermal enhancement, that is, increasing the temperature of the saturated zone soil, it can significantly promote the generation of •OH in the oxidation process of the saturated zone reducing soil, thereby improving the degradation efficiency of organic pollutants such as phenol. However, the traditional heating methods of electric heating and steam heating not only have high energy consumption, but also in practical applications, steam will produce considerable heat loss during transportation and recycling, which reduces the efficiency of steam heating. In order to overcome technical defects, the present invention provides a system and method for converting solar energy into thermal energy and transmitting thermal energy and oxygen to saturated zone soil, so as to increase the production of hydroxyl radicals (•OH) in saturated zone reducing soil, thereby promoting the degradation of pollutants. Summary of the invention

The technical solutions provided by the embodiments of the present invention are described in detail below in conjunction with the drawings.

[0016] In order to better understand the purpose of the present invention, the present invention is described in further detail below.

[0017] The transmission system for remediation of organically contaminated soil based on solar heating enhancement saturated zone provided by the present invention comprises: A data acquisition unit is used to acquire basic data of saturated zone soil and historical data of the transmission system for soil remediation. The integrated data of saturated zone soil include solar radiation intensity, soil temperature, OH concentration, pollutant concentration, thermal energy transmission efficiency and oxygen transmission flow rate. The historical data of the transmission system for organic contaminated soil remediation and the historical data of the transmission system for soil remediation are used to train a random forest model to obtain a transmission control model for soil remediation. The basic data of saturated zone soil include solar radiation intensity, soil temperature, •OH concentration, pollutant concentration, heat transfer efficiency and oxygen transfer flow rate. The historical data of the transmission system for soil remediation includes historical records related to soil remediation, such as solar radiation intensity, soil temperature, •OH concentration, pollutant concentration, heat transfer efficiency, oxygen transfer flow rate parameters and corresponding soil remediation effect data.

[0018] The acquired basic data of saturated zone soil and historical data of soil remediation transmission system are preprocessed to improve the quality and consistency of the data and provide a reliable data basis for subsequent model training.

[0019] The random forest model is trained using the preprocessed data. During the training process, solar radiation intensity, soil temperature, •OH concentration, pollutant concentration, thermal energy transfer efficiency, and oxygen transfer flow parameters are used as input features, and the soil remediation effect is used as the output target. Through iterative training, the model can learn the mapping relationship between input features and output targets, thereby obtaining a transmission control model for soil remediation. This model can predict the effect of soil remediation based on the input soil and environmental parameters, providing guidance for the actual soil remediation process.

[0020] The integrated unit collects solar energy through solar panels and converts solar energy into thermal energy, monitors the calorific value of thermal energy, obtains real-time thermal energy value, collects the amount of oxygen in the oxygen pump, obtains real-time oxygen value, and collects the location of the heat transmission pipeline and the oxygen transmission pipeline; The integrated unit uses solar panels to collect sunlight energy. Solar panels use semiconductor materials and use the photoelectric effect to convert sunlight into electrical energy. Through the built-in heat conversion device, the solar panel further converts the converted electrical energy into thermal energy to provide the required thermal energy for the soil remediation system. During the heat energy conversion and transmission process, the integrated unit monitors the calorific value of the thermal energy in real time. This improves the accurate transmission and effective use of thermal energy, and improves the energy efficiency of the entire system.

[0021] The integrated unit is also responsible for monitoring the amount of oxygen in the oxygen pump. The oxygen pump is a key device for providing oxygen in the system. It is equipped with an oxygen sensor that can monitor the amount of oxygen in the pump in real time and output real-time oxygen values ​​to improve the stability of oxygen supply.

[0022] In addition, the integrated unit also collects the position information of the heat transmission pipeline and the oxygen transmission pipeline. This information is provided in real time through the position sensors installed on the pipeline, which improves the accuracy of the pipeline position and the transmission efficiency, and avoids energy loss or transmission delay caused by incorrect pipeline position.

[0023] In summary, the integrated unit efficiently collects solar energy through solar panels and converts it into thermal energy, while monitoring the calorific value of thermal energy, the amount of oxygen in the oxygen pump, and the location information of the heat and oxygen transmission pipelines in real time, providing a stable and reliable energy and oxygen supply for the entire soil remediation system.

[0024] a data judgment unit, acquiring soil information, receiving soil division requirement information, dividing the soil according to the soil division requirement information, obtaining soil division data, collecting the real-time temperature of each soil division through a temperature sensor in the soil, comparing the real-time temperature of each soil division with a preset target temperature range, if the soil temperature is lower than the preset target temperature range, marking the soil below the preset target temperature range as soil to be heated, collecting soil samples from each soil division, determining the •OH concentration in the soil using a preset chemical analysis method for the soil samples collected in each soil division, obtaining the •OH concentration of each soil division, comparing the •OH concentration of each soil division with a preset target concentration range, if the •OH concentration of the soil division is lower than the preset target concentration range, marking the soil below the preset target concentration range as soil to be oxygenated; The data judgment unit first obtains the basic data of the current saturated zone soil, including key information such as soil type, pollutant distribution, soil moisture, etc., to provide a basic basis for subsequent soil division and remediation work.

[0025] According to the requirements set by the user or the system, the data judgment unit receives the demand information for soil division. This information clarifies the purpose of division (such as improving remediation efficiency, reducing resource consumption, etc.) and the method of division (such as by pollution degree, soil type, etc.), providing guidance for the division of soil zones.

[0026] Based on the received soil division requirement information, the data judgment unit divides the soil into different partitions. Each partition has similar pollution degree, soil type or other key characteristics, so as to carry out targeted remediation measures.

[0027] Through the temperature sensors installed in the soil, the data judgment unit collects the temperature data of each soil partition in real time. This provides accurate data support for evaluating the soil condition and judging whether the temperature needs to be raised.

[0028] The data judgment unit compares the collected soil temperature with the preset target temperature range. If the soil temperature is lower than the preset target temperature range, it means that the area needs to be heated to promote the soil remediation effect, so the soil partition is marked as soil to be heated.

[0029] In order to further understand the soil conditions, the data judgment unit collects soil samples from each soil partition. The collected soil samples are measured according to the preset chemical analysis method to obtain the •OH concentration data in the soil. •OH concentration is one of the important indicators for evaluating the effect of soil remediation. If the •OH concentration of a soil partition is lower than the preset target concentration range, it means that the area needs oxygen supply to promote the degradation of organic pollutants in the soil, so the soil partition is marked as soil to be supplied with oxygen.

[0030] A transmission unit, which substitutes the information of the soil to be oxygenated into the transmission control model of soil remediation to obtain oxygen transmission control parameters, transmits the oxygen transmission control parameters to the oxygen pump and the oxygen control valve, and the oxygen pump and the oxygen control valve execute the oxygen transmission control parameters to transmit oxygen to the soil to be oxygenated, substitutes the information of the soil to be heated into the transmission control model of soil remediation to obtain heat transmission control parameters, transmits the heat transmission control parameters to the heat pump and the hot gas control valve, and the heat pump and the hot gas control valve execute the heat transmission control parameters to transmit heat to the soil to be heated; The transmission unit receives soil information to be oxygenated from the data judgment unit, including soil partition, location, and OH concentration data. This information is substituted into the soil remediation transmission control model, which calculates the optimal oxygen delivery control parameters based on the input information, including oxygen flow rate and oxygen delivery time. The calculated oxygen delivery control parameters are then transmitted to the oxygen pump and oxygen control valve.

[0031] The oxygen pump starts according to the received control parameters, and delivers oxygen to the soil area to be delivered through the oxygen transmission pipeline. The oxygen control valve adjusts the flow and pressure of oxygen according to the parameters to improve the accurate and efficient delivery of oxygen to the target area. The transmission unit receives the soil information to be heated from the data judgment unit, including soil partition, location and temperature data.

[0032] This information is fed into the soil remediation transfer control model, which calculates the optimal heat transfer control parameters based on the input information, including heat output and transfer time. The calculated heat transfer control parameters are then transmitted to the heat pump and hot gas control valve.

[0033] The heat pump starts according to the received control parameters, converts solar energy into thermal energy through the thermal energy conversion device, and transmits the thermal energy to the soil area to be heated through the heat transfer pipeline. The hot air control valve adjusts the flow and temperature of the thermal energy according to the parameters, thereby improving the accuracy and efficiency of thermal energy delivery to the target area.

[0034] Through the above steps, the transmission unit successfully converted the information of the soil to be treated into specific control parameters and transmitted them to the corresponding equipment to perform operations, thus achieving precise remediation of saturated organically contaminated soil.

[0035] A control unit receives an expected temperature value of the saturated zone soil and an expected •OH concentration value of the saturated zone soil, collects temperature of the soil after receiving heat and compares it with the expected temperature value of the saturated zone soil to obtain a heat error value, obtains soil information corresponding to the heat error value, obtains soil information with a heat error value, measures •OH concentration in the soil using a preset chemical analysis method, collects soil samples from the soil after receiving oxygen and compares it with the expected •OH concentration value of the saturated zone soil to obtain an •OH concentration error value, obtains soil information corresponding to the •OH concentration error value, obtains soil information with a •OH concentration error value, optimizes a transmission control model for soil remediation using a genetic algorithm based on the soil information with the heat error value and the soil information with the •OH concentration error value to obtain an optimized transmission control model for soil remediation, uses the optimized transmission control model for soil remediation to process data on soil information to be supplied with oxygen and soil information to be heated to obtain optimized oxygen transmission control parameters and optimized heat transmission control parameters, sends the optimized oxygen transmission control parameters to the oxygen pump and the oxygen control valve, and sends the optimized heat transmission control parameters to the heat pump and the hot gas control valve.

[0036] The control unit first receives the expected temperature and expected •OH concentration of the saturated zone soil. These expected values ​​are set according to the soil remediation goals and actual conditions, providing a benchmark for subsequent control and optimization. The temperature of the soil after receiving heat is collected, and the actual temperature data of the soil is obtained in real time using a temperature sensor.

[0037] The actual soil temperature collected is compared with the expected temperature value to calculate the heat error value. This error value reflects the difference between the soil temperature and the expected value, which is an important basis for subsequent optimization control.

[0038] According to the heat error value, the control unit can obtain the corresponding soil information, that is, the soil information with the heat error value. This information includes the location, type, degree of contamination, etc. of the soil, which helps to locate the problem area and carry out targeted treatment. •OH concentration measurement and comparison, soil samples are collected from the soil after receiving oxygen, and the •OH concentration in the soil is measured according to the preset chemical analysis method. The measured •OH concentration is compared with the expected •OH concentration value to calculate the •OH concentration error value. This error value reflects the difference between the •OH concentration in the soil and the expected value, and is also used for subsequent optimization control.

[0039] According to the •OH concentration error value, the control unit can obtain the corresponding soil information, that is, the soil information with the •OH concentration error value. This information also includes the location, type, degree of contamination, etc. of the soil, providing key data for optimization control. Based on the soil information with the heat error value and the soil information with the •OH concentration error value, the control unit uses a genetic algorithm to optimize the transmission control model of soil remediation. By continuously iterating and adjusting the model parameters, the model can more accurately reflect the actual situation and needs of the soil remediation process.

[0040] The optimized soil remediation transmission control model is used to process the information of the soil to be oxygenated and the soil to be heated. According to the model calculation results, the optimized oxygen transmission control parameters and the optimized heat transmission control parameters are obtained. The optimized oxygen transmission control parameters are sent to the oxygen pump and the oxygen control valve to guide them to perform precise oxygen transmission operations. The optimized heat transmission control parameters are sent to the heat pump and the hot gas control valve to guide them to perform precise heat transmission operations.

[0041] Specifically, in the transmission system for remediation of saturated organically contaminated soil based on solar heating enhancement according to the present invention, the data acquisition unit is further used for: Acquire the historical data of the transmission system for organic contaminated soil remediation, including solar radiation intensity, soil temperature, OH concentration, pollutant concentration, thermal energy transmission efficiency, oxygen transmission flow parameters and corresponding soil remediation effect data, pre-process the basic data of saturated zone soil and the historical data of the transmission system for soil remediation, and obtain the pre-processed basic data of saturated zone soil and the historical data of the transmission system for soil remediation; The random forest model is trained using the preprocessed saturated zone soil basic data and the historical data of the soil remediation transmission system. The solar radiation intensity, soil temperature, •OH concentration, pollutant concentration, thermal energy transfer efficiency, and oxygen transmission flow parameters are used as input features, and the soil remediation effect is used as the output target. Through iterative training, the model can learn the mapping relationship between solar radiation intensity, soil temperature, •OH concentration, pollutant concentration, thermal energy transfer efficiency, oxygen transmission flow parameters and soil remediation effect, and obtain the transmission control model of soil remediation.

[0042] The data acquisition unit first acquired a large amount of historical data of the transmission system for organic contaminated soil remediation. These data cover key parameters such as solar radiation intensity, soil temperature, •OH concentration, pollutant concentration, thermal energy transmission efficiency, and oxygen transmission flow. These data are the basis for evaluating soil remediation effects and training models.

[0043] After obtaining the raw data, the data acquisition unit will preprocess the data. The preprocessing process includes cleaning the data (removing invalid or erroneous data), filling missing values ​​(supplementing incomplete data), processing outliers (correcting data that deviates from the normal range), etc. The purpose of this step is to improve the accuracy and reliability of the data and lay a solid foundation for the subsequent training process.

[0044] After the preprocessing is completed, the data acquisition unit will use these data to train the random forest model. In this process, parameters such as solar radiation intensity, soil temperature, •OH concentration, pollutant concentration, thermal energy transfer efficiency, and oxygen transfer flow rate are used as input features, and the soil remediation effect is set as the output target.

[0045] Through iterative training, the random forest model can learn the mapping relationship between these input features and soil remediation effects. This mapping relationship can help us understand the impact of different parameters on soil remediation effects and provide a basis for subsequent prediction and optimization.

[0046] After training, the random forest model can predict the optimal soil remediation control parameters (such as oxygen flow, oxygen delivery time, heat energy output, etc.) based on the input soil parameters (such as solar radiation intensity, soil temperature, etc.). These control parameters are the key to achieving precise control of the soil remediation process.

[0047] In summary, the data acquisition unit acquires and processes the historical data of the transmission system for organic contaminated soil remediation, and uses this data to train a random forest model that can predict and optimize the soil remediation process, and finally obtains an effective transmission control model for soil remediation.

[0048] Specifically, the transmission system for remediation of saturated organically contaminated soil based on solar heating enhancement described in the present invention, the integrated unit is also used for: Solar panels collect sunlight energy, which uses the photoelectric effect of semiconductor materials to convert sunlight into electrical energy, and then convert electrical energy into thermal energy through built-in thermal conversion devices; During the heat energy conversion process, the integrated unit monitors the calorific value of the heat energy in real time. The integrated unit also collects the amount of oxygen in the oxygen pump. The oxygen pump is a device used to provide oxygen in the system. The oxygen pump is equipped with an oxygen sensor to monitor the amount of oxygen in the pump in real time and output the real-time oxygen value. The integrated unit also collects the position information of the heat transfer pipeline and the oxygen transfer pipeline, and provides the pipeline position data in real time through the position sensors installed on the pipeline.

[0049] The integrated unit first uses solar panels to collect sunlight energy. The solar panels contain semiconductor materials. When sunlight shines on the semiconductor materials, a photoelectric effect occurs, converting the sunlight into electrical energy. The thermal conversion device built into the integrated unit further converts the converted electrical energy into thermal energy. This step realizes the effective use of solar energy and provides the required thermal energy for the soil remediation process.

[0050] During the heat conversion process, the integrated unit monitors the calorific value of the heat in real time. This function improves the effective management and control of heat energy, allowing the system to adjust the heat output according to actual conditions to meet the needs of soil remediation.

[0051] The integrated unit is also responsible for collecting the amount of oxygen in the oxygen pump. The oxygen pump is a key device for providing oxygen in the system, and an oxygen sensor is installed inside it. The oxygen sensor can monitor the amount of oxygen in the pump in real time and output real-time oxygen values. These values ​​are processed and recorded by the integrated unit for subsequent system control and optimization.

[0052] The integrated unit is also responsible for collecting the position information of the heat transfer pipeline and the oxygen transfer pipeline. This function is achieved through position sensors installed on the pipeline, which can provide real-time pipeline position data. Position data is crucial for improving the precise control and optimization of the transmission system. By monitoring the position of the pipeline in real time, the system can adjust the transmission path and transmission speed in time to achieve a more efficient soil remediation process.

[0053] In summary, the integrated unit realizes the effective use of solar energy, the precise transmission of heat energy and oxygen, and the real-time monitoring and control of various parts of the system through multiple functions such as collecting solar energy and converting it into heat energy, real-time monitoring of the calorific value of heat energy, collecting the amount of oxygen in the oxygen pump, and collecting the location information of the heat transmission pipeline and the oxygen transmission pipeline. These functions together constitute the core value of the integrated unit and provide strong support for the transmission system based on solar heating to enhance the remediation of saturated organic contaminated soil.

[0054] Specifically, in the transmission system for remediation of organically contaminated soil with saturated zone enhanced by solar heating according to the present invention, the data judgment unit is further used for: For each soil partition, the data judgment unit will collect soil samples, and the collected soil samples will be measured according to the preset chemical analysis method to obtain the •OH concentration data in the soil; The preset chemical analysis method includes collecting soil samples for each soil partition, using titration analysis to determine the concentration of •OH in the soil through chemical reactions, and determining the concentration of •OH through color changes or conductivity changes during the titration process; The data judgment unit compares the measured •OH concentration of each soil partition with the preset target concentration range. If the •OH concentration of the soil partition is lower than the preset target concentration range, the soil partition is marked as soil to be oxygenated, and oxygen needs to be added to the soil partition to increase the •OH concentration.

[0055] The data judgment unit first obtains soil information and divides the soil according to the soil division requirement information to obtain different soil partition data. For each soil partition, the data judgment unit will collect soil samples to improve the accuracy and representativeness of subsequent analysis.

[0056] The collected soil samples will be measured according to the preset chemical analysis method to obtain the •OH concentration data in the soil. The preset chemical analysis method mainly includes the use of titration analysis to determine the concentration of •OH in the soil through chemical reactions. During the titration process, the concentration of •OH can be determined by observing the color change or conductivity change.

[0057] The data judgment unit compares the measured •OH concentration of each soil partition with the preset target concentration range to evaluate whether the •OH concentration in the soil reaches the expected level. If the •OH concentration of a soil partition is lower than the preset target concentration range, the data judgment unit will mark the soil partition as soil to be oxygenated. This means that oxygen needs to be added to the area to increase the •OH concentration, thereby promoting the degradation of organic pollutants and soil remediation effects.

[0058] In summary, the data judgment unit realizes accurate monitoring and management of the soil remediation process through the steps of soil sample collection, •OH concentration determination, concentration comparison, and marking of soil to be oxygenated. This provides strong support for improving the soil remediation effect and efficiency.

[0059] Specifically, the transmission system for remediation of saturated organically contaminated soil based on solar heating enhancement according to the present invention, the transmission unit is also used for: The transmission unit first receives the soil information to be supplied with oxygen from the judgment unit, and the soil information to be supplied with oxygen includes soil partition, location and OH concentration data; Substituting the soil information to be oxygenated into the transmission control model of soil remediation, the transmission control model of soil remediation calculates the optimal oxygen delivery control parameters according to the input soil information to be oxygenated, and the oxygen delivery control parameters include oxygen flow rate and oxygen delivery time; The calculated oxygen supply control parameters are transmitted to the oxygen pump and the oxygen control valve. The oxygen pump is started according to the control parameters to transport the oxygen to the soil area to be supplied with oxygen through the oxygen transmission pipeline. The oxygen control valve adjusts the flow and pressure of the oxygen according to the parameters. The transmission unit receives the soil information to be heated from the data judgment unit, where the soil information to be heated includes soil partition, location and temperature data; Substituting the soil information to be heated into the transmission control model of soil remediation, the transmission control model of soil remediation calculates the optimal heat transmission control parameters according to the input soil information to be heated, and the heat transmission control parameters include heat energy output and transmission time; The heat pump is started according to the heat transfer control parameters, converts solar energy into thermal energy through the thermal energy conversion device, and transmits the thermal energy to the soil area to be heated through the heat transfer pipeline. The hot air control valve adjusts the flow and temperature of the thermal energy according to the parameters.

[0060] The transmission unit first receives the soil information to be oxygenated sent by the data judgment unit. This information includes soil partition, specific location and OH concentration data in detail, providing accurate basic data for subsequent operations. The transmission unit substitutes this soil information to be oxygenated into the transmission control model of soil remediation. The model can intelligently calculate the optimal oxygen transmission control parameters based on the input soil information. These parameters specifically cover oxygen flow and oxygen transmission time, improving the accuracy and efficiency of oxygen transmission.

[0061] When the oxygen supply control parameters are calculated, the transmission unit quickly transmits these parameters to the oxygen pump and oxygen control valve. The oxygen pump starts immediately according to the received parameters and accurately delivers oxygen to the soil area to be supplied through the oxygen transmission pipeline. At the same time, the oxygen control valve also accurately adjusts the oxygen flow and pressure according to the parameters to improve the stability and effectiveness of oxygen transmission.

[0062] In addition to processing the soil information to be oxygenated, the transmission unit is also responsible for receiving the soil information to be heated sent by the data judgment unit. The soil information to be heated includes soil partitions, specific locations and temperature data, providing an accurate target for heat energy transmission.

[0063] The transmission unit inputs the soil information to be heated into the soil remediation transmission control model, and the model calculates the optimal heat transmission control parameters based on this information. These parameters specifically include heat output and transmission time, which improves the accuracy and efficiency of heat transmission.

[0064] The heat pump starts according to the heat transfer control parameters and efficiently converts solar energy into heat energy through the heat energy conversion device. The heat energy is then accurately transported to the soil area to be heated through the heat transfer pipeline. At the same time, the hot gas control valve also accurately adjusts the flow and temperature of the heat energy according to the parameters to improve the stability and effectiveness of heat energy transmission.

[0065] In summary, the transmission unit achieves precise control and management of the soil remediation process by receiving information about the soil to be oxygenated and heated, calculating oxygen transmission control parameters and heat transmission control parameters, and accurately transmitting oxygen and heat energy to the target soil area. This process not only improves the efficiency and quality of soil remediation, but also improves the effective use of resources and the sustainable development of the environment.

[0066] Specifically, in the transmission system for remediation of saturated organically contaminated soil based on solar heating enhancement according to the present invention, the control unit is also used for: Collecting soil information with heat error values ​​and soil information with •OH concentration error values, wherein the soil information with heat error values ​​and the soil information with •OH concentration error values ​​both include soil location, error value size, and soil type; According to the expected temperature value of the saturated zone soil and the expected •OH concentration value of the saturated zone soil, the optimization target is determined, and the optimization target is to reduce the heat error value and the •OH concentration error value, so that the soil state is close to the expected temperature and the expected •OH concentration value; Initialize the population, randomly generate a certain number of initial design schemes, i.e., the population, according to the parameter range of the transport control model of soil remediation, and each design scheme represents a group of model parameters; According to the heat error value and •OH concentration error value, a fitness function is constructed. The fitness function is used to evaluate the pros and cons of each design scheme, and each design scheme is each individual; According to the fitness function, individuals with higher fitness are selected from the population as parents for subsequent crossover and mutation operations; Crossover operation: perform crossover operation on the selected parent individuals to generate new offspring individuals; Mutation operation: perform mutation operation on offspring individuals to introduce new genotypes and increase the diversity of the population; Iterative optimization, repeating the crossover and mutation operations until the preset maximum number of iterations is reached. In each iteration, a new population is generated, and the individual with the highest fitness is selected from the final population as the optimized transmission control model parameters for soil remediation; Sending optimized oxygen transmission control parameters to the oxygen pump and oxygen control valve to guide oxygen transmission; The optimized heat transfer control parameters are sent to the heat pump and hot gas control valve to guide the heat transfer.

[0067] The control unit first receives the expected temperature value and expected •OH concentration value of the saturated zone soil. The temperature of the soil after receiving heat is collected and compared with the expected temperature value to obtain the heat error value. The soil sample after receiving oxygen is collected and compared with the expected •OH concentration value to obtain the •OH concentration error value. Finally, the soil information corresponding to these error values ​​is obtained, including soil location, error value size, and soil type.

[0068] According to the received expected temperature value and expected •OH concentration value of the saturated zone soil, the control unit clearly defines the optimization goal, which is to reduce the heat error value and •OH concentration error value so that the soil state is as close to the expected temperature and •OH concentration values ​​as possible.

[0069] Initialize the population, the control unit randomly generates a certain number of initial design schemes according to the parameter range of the transport control model of soil remediation, and these design schemes together constitute the population. Each design scheme represents a set of model parameters.

[0070] Construct a fitness function, and use the heat error value and the •OH concentration error value to control the control unit to construct the fitness function.

[0071] This function is used to evaluate the quality of each design solution, each of which is considered as an individual.

[0072] Select parent individuals. The control unit selects individuals with higher fitness from the population according to the fitness function as parents for subsequent crossover and mutation operations.

[0073] Perform crossover and mutation operations. For the selected parent individuals, the control unit performs a crossover operation to generate new offspring individuals. Perform mutation operations on the offspring individuals to introduce new genotypes, thereby increasing the diversity of the population.

[0074] Iterative optimization, the control unit repeatedly performs crossover and mutation operations until the preset maximum number of iterations is reached. In each iteration, a new population is generated, and the individual with the highest fitness is selected from the final population as the optimized transmission control model parameters for soil remediation.

[0075] The control unit sends the optimized oxygen transmission control parameters to the oxygen pump and oxygen control valve to guide the accurate transmission of oxygen. The optimized heat transmission control parameters are sent to the heat pump and hot gas control valve to guide the effective transmission of heat.

[0076] In summary, the control unit optimizes and regulates the soil remediation process through a series of complex and delicate operations. This not only improves the soil temperature and •OH concentration to reach the expected values, but also improves the effect and efficiency of soil remediation.

[0077] The present invention solves the problems of high energy consumption, large heat loss during steam transportation and recycling, and low steam heating efficiency in the traditional heating method by the following methods: The present invention uses solar panels to collect solar energy and convert it into thermal energy. Compared with traditional electric heating and steam heating, this method significantly reduces energy consumption, because solar energy is a renewable energy source, and its use does not incur additional costs and also reduces dependence on fossil fuels. Through the built-in heat conversion device, the present invention can directly convert electrical energy into thermal energy, reducing heat loss during the transmission and recycling of thermal energy. This direct conversion method improves the utilization efficiency of thermal energy and reduces energy loss during transmission.

[0078] The present invention adopts an intelligent control system, obtains soil basic data and historical remediation data through a data acquisition unit, and uses a random forest model to train a transmission control model for soil remediation. This model can achieve precise control of soil temperature and •OH concentration, thereby improving the efficiency of heating and oxygen delivery and reducing unnecessary energy consumption.

[0079] The integrated unit monitors the calorific value of heat energy and the amount of oxygen in the oxygen pump in real time, while the data judgment unit collects soil temperature and OH concentration in real time. This information is fed back in time through the transmission unit and control unit to adjust the transmission of heat and oxygen. This real-time monitoring and feedback mechanism improves the efficient use of energy and avoids energy waste.

[0080] The control unit uses a genetic algorithm to optimize the soil remediation transmission control model to obtain optimized oxygen transmission control parameters and heat transmission control parameters. These optimized parameters further improve the efficiency of heating and oxygen transmission, reduce energy consumption, and make the entire system more efficient and energy-saving.

[0081] The data judgment unit divides the soil into different zones and heats and supplies oxygen to each zone according to its actual needs. The zone management method avoids energy waste caused by unified heating and oxygen supply, because each zone can be independently controlled according to actual needs, achieving accurate energy allocation.

[0082] By utilizing solar energy, a renewable energy source, the present invention reduces dependence on fossil fuels, reduces carbon emissions, and meets environmental protection requirements. This environmentally friendly heating method not only reduces energy consumption, but also helps protect the earth's environment.

[0083] In summary, the present invention effectively solves the problems of high energy consumption, large heat loss and low heating efficiency of traditional heating methods by utilizing solar energy heating, reducing heat loss, intelligent control system, real-time monitoring and feedback, optimizing model parameters, zoning management and environmental friendliness.
