[0018] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are only examples, and those skilled in the art may think of other obvious variations.

[0019] Reference Figure 1 As shown, an ecological environment protection system for sorting and managing historical solid waste includes: a solid waste collection module, an intelligent sorting module, a processing and disposal module, an environmental monitoring module and a central control module; The solid waste collection module is the starting point of the entire system. It is equipped with a variety of garbage storage containers, which are designed with a strict sealing mechanism to prevent secondary pollution to the environment during the collection and transportation of waste. Through an efficient logistics network, these properly sealed solid wastes are safely transported to the sorting and processing area to prepare for subsequent classification work.

[0020] The intelligent sorting module uses advanced image recognition technology and machine learning algorithms to accurately classify the solid waste that arrives. This module can not only quickly distinguish between recyclables, hazardous waste, kitchen waste and other waste, but also continuously optimize its classification accuracy as the running time increases, thereby improving the recycling rate of resources and reducing the environmental risks that may be caused by incorrect classification.

[0021] The treatment and disposal module takes targeted treatment measures based on the identification results of the intelligent sorting module. Recyclables are pre-processed by washing, crushing, and packaging to facilitate subsequent recycling; hazardous waste is specially treated to ensure that the harmful substances in it are safely disposed of; kitchen waste is converted into fertilizer or energy through biodegradation and other methods; and other waste is landfilled or incinerated according to actual conditions, while emissions are strictly controlled to avoid adverse effects on the environment.

[0022] The environmental monitoring module plays a vital role in the entire treatment process. It uses a sensor network to monitor the concentration of pollutants in the atmosphere, water and soil in real time to ensure that the treatment process does not exceed the limits of the environmental carrying capacity. Once abnormal data is detected, an alarm is immediately sent to the central control module so that timely measures can be taken to make adjustments.

[0023] As the "brain" of the entire system, the central control module not only receives and processes data from the environmental monitoring module, but also dynamically regulates each link of solid waste collection, intelligent sorting, treatment and disposal according to preset environmental protection standards and efficient operation algorithms. This intelligent management method not only improves the efficiency of solid waste treatment, but also ensures that the entire treatment process meets the high standards of ecological and environmental protection, providing strong support for the efficient sorting management of historical solid waste and ecological and environmental protection.

[0024] The collection module is equipped with sealed containers and an efficient logistics network to effectively prevent secondary pollution and ensure transportation safety. The intelligent sorting module uses advanced technology to accurately classify and continuously optimize to improve resource recycling rates. The treatment and disposal module conducts targeted treatment based on the classification results to achieve reasonable disposal of various types of garbage. The environmental monitoring module monitors in real time to ensure environmental safety during the treatment process. The central control module, as the "brain", realizes dynamic regulation of each link, which not only improves the treatment efficiency, but also ensures that the treatment process meets high environmental protection standards, providing strong support for solid waste treatment and environmental protection.

[0025] The use process of the present invention is as follows: historical solid waste is identified and classified through high-precision sensors, and the data of various types of waste are uploaded to the central processing unit. The system automatically plans the sorting path according to the nature of the waste, and guides the robotic arm or conveyor belt to perform precise sorting. The sorted waste enters the corresponding processing modules, such as harmless treatment, resource recovery, etc., to achieve intelligent monitoring and management throughout the process. The system can also monitor the treatment effect in real time, optimize the sorting strategy, ensure the efficient and safe treatment of historical solid waste, and reduce the negative impact on the ecological environment.

[0026] In summary, the advantages of the present invention are: high-precision identification and classification technology ensures that waste is accurately processed; intelligent path planning and automatic sorting functions greatly improve the sorting speed and accuracy; modular design makes the processing flow flexible and diverse, adapting to different waste types; full-process intelligent monitoring and management reduces labor costs while improving safety; real-time monitoring and optimization strategies ensure continuous optimization of processing effects, effectively reduce the negative impact on the ecological environment, and promote sustainable development.

Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions only describe the principles of the present invention. The present invention may be subject to various changes and improvements without departing from the spirit and scope of the present invention.
