Description

Technical Field

[0001] The invention relates to the technical field of garbage treatment, in particular to an aerobic treatment method and system for landfill management. Background Art

[0002] With the rapid development of society, the amount of domestic waste in my country's cities and towns has also soared. At present, landfill is still the main way to deal with waste. However, the garbage in the landfill generally exceeds the designed storage capacity. Long-term overload operation leads to greater environmental risks and safety hazards in the landfill. Therefore, it is of great significance to carry out ecological restoration projects for domestic waste landfills to make them quickly and stably.

[0003] Aerobic stabilization technology can accelerate the decomposition of biodegradable organic matter in garbage by microorganisms and reduce greenhouse gas emissions, so it has attracted much attention in landfill management. However, traditional aerobic stabilization technology is not associated with intelligent equipment, information transmission is not timely, aerobic remediation effects are not intuitive, and control methods are not accurate. It cannot solve the problems of uneven gas distribution and insufficient oxygen reaction. In addition, the construction efficiency of aerobic facilities is low, which easily leads to repeated work and waste of resources and costs.

[0004] At present, aerobic treatment methods for landfill management face many challenges in their implementation. First, the real-time synchronization and accurate comparison between virtual models and actual construction conditions have not been effectively solved, resulting in a lack of accuracy and timeliness in construction progress management. Secondly, the collection and analysis of environmental monitoring data are often carried out in isolation, making it difficult to form an organic connection with the construction progress and management effects, limiting the timely identification and early warning of environmental risks. Furthermore, existing methods lack sufficient flexibility and adaptability when dealing with complex and changing construction environments, and are unable to dynamically adjust construction strategies according to real-time conditions. Therefore, it is urgent to develop an aerobic treatment method for landfill management that can integrate virtual field models, real-time monitoring, and dynamic adjustment to achieve refined, intelligent, and environmentally friendly management of landfill management. Summary of the invention

[0069] Example 1

[0070] Reference Figure 1 and Figure 2 , which is the first embodiment of the present invention, provides an aerobic treatment method for landfill management, comprising the following steps:

[0071] S1. Collecting actual environment information, building a virtual site model, and predicting virtual construction information through the virtual site model.

[0072] The virtual site model includes a BIM model and a three-dimensional site layout model;

[0073] The method for constructing the BIM model includes:

[0074] Establish a landfill entity model through modeling software, and establish corresponding family libraries for all sub-models of the entity model;

[0075] Unify all sub-models together to obtain the BIM model;

[0076] Use detection tools to identify collision problems in the BIM model, and then adjust the parametric components in the family library;

[0077] Until the BIM model meets the design specifications;

[0078] When constructing the BIM model, use GPS equipment and 3D laser scanners (such as Leica RTC360) to conduct a full-scale scan of the landfill to obtain accurate 3D data of terrain, landforms and existing facilities. At the same time, use drones (such as DJI Phantom 4RTK) for aerial photography to obtain a bird's-eye view of the landfill and surrounding environment information. Autodesk Revit2024 is selected as the main modeling software, and the point cloud data obtained from GPS and laser scanners are imported into Revit. Use Revit's terrain tools to create an accurate terrain model based on the point cloud data. According to the design drawings and field data, the main structures of the landfill, such as the leachate collection system, gas collection system, and cover layer, are established, and corresponding family libraries are created for each sub-model, such as the leachate collection pipe family, the gas collection well family, and the cover layer material family. All sub-models are imported into the main project file, and the link function of Revit is used to ensure the correct association and positioning between the sub-models. Use Autodesk Navisworks 2024 Perform collision detection, export collision reports, identify conflict points in the BIM model, return to Revit, and adjust the parametric components in the family library according to the collision report. For example, adjust the routing of the leachate collection pipeline to avoid conflict with the gas collection well. Repeat this process until all collision issues are resolved.

[0079] The method for constructing the three-dimensional site layout model includes:

[0080] Collecting geographic environmental data of the site through a geographic information system;

[0081] Inputting the geographical environment data into modeling software, and establishing a three-dimensional site layout model through the modeling software;

[0082] When constructing the 3D site layout model, ArcGIS Pro 2.9 was selected as the main GIS software, LiDAR (Light Detection and Ranging) technology was used to obtain a high-precision digital elevation model (DEM), and a Leica ALS80 laser scanner was used for aerial LiDAR scanning to obtain point cloud data.

[0083] The method for constructing the virtual site model comprises:

[0084] Establish a standard coordinate system and adjust the BIM model and 3D site layout model according to the standard coordinate system;

[0085] Import the BIM model into the 3D site layout model;

[0086] Check the integration of the BIM model and the site model. If the sub-model detection result is not aligned, adjust the parametric components until the sub-model detection result is aligned. If the sub-model detection result is aligned, output the virtual site model.

[0087] Adopting the WGS84 / UTM projection coordinate system, which is a universal coordinate system, and the real-time dynamic (RTK) measurement method, a Trimble R12i GNSS receiver was used to set at least 4 control points on the landfill site. Open Autodesk Revit 2024, load the previously created BIM model, apply the "shared coordinate system" function, align the model to the actual geographic location, and import the BIM model into the 3D site layout model.

[0088] S2. Monitor actual construction information, and then compare the actual construction information with the virtual construction information to obtain dynamic adjustment information.

[0089] When comparing the actual construction information with the virtual construction information, the specific steps include:

[0090] Mark the key phases of the construction phase as synchronization points and mark the same synchronization points in the simulation software;

[0091] Make a schedule of X days and mark the synchronization points as T 1 、T 2 ,……,T N , N<X;

[0092] Collect actual construction information at the end of each day and compare the actual progress with the virtual construction information;

[0093] Calculate the difference percentage between the actual progress and the planned progress, and determine whether the difference percentage is equal to 0. If the determination result is equal to 0, no dynamic adjustment is performed; if the determination result is not equal to 0, dynamic adjustment is performed.

[0094] Repeat the monitoring of actual progress every day and calculate the new difference percentage. When the new difference percentage is not equal to 0, the virtual construction information is updated through dynamic adjustment;

[0095] The calculation formula of the difference percentage is expressed as:

[0096] D t =P t -A t ;

[0097] Where D t Expressed as percentage difference, P t It is expressed as the planned progress of the tth day, A tExpressed as the actual progress on day t;

[0098] When D t When it is >0, it means that the actual progress lags behind the planned progress;

[0099] When D t When <0, it means the actual progress is ahead of the planned progress;

[0100] In the specific implementation, for example, a 30-day construction schedule is formulated, and key synchronization points are set: the 5th day, the 10th day, and the 20th day. A detailed work plan and progress target are formulated for each time period. After that, the actual progress data is collected at the end of each day, and the actual progress is compared with the planned progress. The difference percentage between the actual progress and the planned progress is calculated. For example, at the end of the first day, the planned completion rate is 20%, and the actual completion rate is 10%, with a difference of 10%. Based on the actual progress, dynamic adjustments need to be made;

[0101] Among them, Figure 2 As shown, when monitoring actual construction information, different actual data are also collected through a variety of different sensors to ensure the normal operation of the construction.

[0102] The step of dynamic adjustment includes:

[0103] Recalculate the average daily progress required to reach the next synchronization point based on the actual progress;

[0104] Input the new daily average progress into the simulation software and use the simulation software to adjust the catch-up plan or slowdown plan;

[0105] The calculation formula for the average daily progress is expressed as:

[0106]

[0107] In the formula, R t It is expressed as the average daily progress, t is the current day, P Tn Expressed as the percentage of the planned progress from the current to the next synchronization point, T n The number of days to the next synchronization point;

[0108] For example, if 90% of the work needs to be completed in the remaining 4 days, the daily average progress should be 22.5%. The newly calculated daily average progress is input into the simulation software, and the simulation software automatically adjusts the subsequent schedule and resource allocation. The simulation software generates a feasible catch-up plan based on the new progress requirements, evaluates the feasibility and cost of various adjustment plans, selects the best plan and implements it;

[0109] Continue to monitor actual progress daily and make dynamic adjustments if new deviations emerge.

[0110] S3. Input the actual environment information and the dynamic adjustment information into the twin data platform, analyze the received data through the twin data platform, and output feedback information and adjustment methods.

[0111] The analysis step of the twin data platform includes analyzing the actual environment information and analyzing the dynamic adjustment information, wherein;

[0112] The steps of analyzing the actual environment information by the twin data platform include:

[0113] Preset data types and establish corresponding security thresholds based on the data types;

[0114] When the actual environment information corresponding to a certain data type exceeds the safety threshold, the data type is recorded and the collection interval is shortened;

[0115] This data type is classified into mild, moderate, and severe according to the degree of exceeding the safety threshold;

[0116] When analyzing the actual environment, the preset data types and corresponding security thresholds are expressed in a table as follows:

[0117] Table 1: Schematic diagram of preset data types and security thresholds:

[0118] Serial number Data Types Safety threshold 1 Methane concentration 5％ 2 Leachate water level 2 meters 3 Groundwater pH The safety threshold range is 6.5-8.5 4 Landfill surface settlement 50 cm / year

[0119] If the methane concentration is detected to reach 6.2%, the system will mark "methane concentration" as an abnormal state and shorten the sampling interval of this data type. In this example, the sampling interval of methane concentration will be shortened from 60 minutes to 30 minutes. Secondly, the minimum sampling interval is set to 5 minutes to prevent too frequent sampling;

[0120] According to the degree of exceeding the safety threshold, the anomaly is divided into mild, moderate and severe. Mild: exceeding the safety threshold by no more than 10%; moderate: exceeding the safety threshold by 10%-30%; severe: exceeding the safety threshold by more than 30%. In this case, the methane concentration of 6.2% exceeds the safety threshold of 5%, which is 24%, so it is classified as a moderate anomaly.

[0121] The step of analyzing the dynamic adjustment information by the twin data platform includes:

[0122] Query whether the data type currently has records. If so, combine the actual environment information corresponding to the data type with the dynamic adjustment information to predict whether the actual environment information is within the safety threshold. If not, re-update the dynamic adjustment information until the safety threshold is reached. If so, predict whether the actual environment information corresponding to the remaining data types reaches the safety threshold. Stop prediction until all of them reach the safety threshold.

[0123] The system queries the current abnormal data types. In this case, it is found that the "methane concentration" is in an abnormal state. For each abnormal data type, the system combines the actual environmental information with possible dynamic adjustment measures to predict future environmental changes. For example, the system may consider increasing the gas extraction rate as an adjustment measure. Assume that the prediction model shows that increasing the gas extraction rate by 20% may reduce the methane concentration to 5.5% within 4 hours. If the prediction results show that the adjusted environmental information still does not reach the safety threshold, the system will readjust the parameters and conduct a new round of predictions. In this case, the system may try to increase the gas extraction rate by 25%, and predict that the methane concentration may drop to 4.9% within 6 hours, reaching the safety threshold.

[0124] The feedback information includes the comparison between the actual progress and the planned progress, the identified potential risks and risk levels, and the adjustment methods include progress adjustment suggestions and risk mitigation measures;

[0125] The feedback information and the adjustment method are output to a visual display device.

[0126] In summary, by building a virtual site model and comparing it with the actual construction information in real time, dynamic synchronization of the virtual and actual environments is achieved. By combining the BIM model and the three-dimensional site layout model, a highly accurate digital twin environment is created. By setting synchronization points and daily progress comparisons, the system can calculate the difference percentage in a timely manner, thereby accurately quantifying the construction progress deviation, which not only improves the accuracy of progress management, but also greatly improves the response speed.

[0127] Integrate environmental monitoring data and construction progress management into the twin data platform. By presetting data types and safety thresholds, the system can automatically identify environmental risks and adjust data collection frequency according to the degree of risk. At the same time, the environmental data analysis results are combined with dynamic adjustment information to predict the potential impact of construction adjustments on the environment. Dynamic adjustment information is updated preferentially through data types that exceed the safety threshold, which greatly improves the environmental safety of the project.

[0138] Example 3

[0139] On the basis of the previous two embodiments, this embodiment provides an aerobic treatment method for landfill management. In order to verify the beneficial effects of the present invention, scientific demonstration is carried out through simulation experiments.

[0140] Comparative example: The progress is adjusted manually based on human experience, and only the BIM model and the three-dimensional site layout model are built, and the two models cannot be combined.

[0141] Object of investigation: a landfill with an area of ​​10 hectares; Experimental period: 90 days; Key indicators: construction schedule deviation, methane concentration control, leachate water level control, number of environmental risk events and decision response time.
