Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of medical waste treatment, and in particular to a medical waste treatment monitoring method based on artificial intelligence. Background Art
[0002] The treatment and monitoring of medical waste are of great significance to public health and environmental protection. The treatment process includes classification, collection, transportation, storage and terminal disposal. However, since medical waste is infectious and toxic, leachate diffusion and gas migration may occur during the landfill process. If not handled properly, it will pollute the environment and pose a threat to residents' health.
[0003] At present, the monitoring method of medical waste treatment mainly relies on sampling at monitoring points and periodic inspections. This method is difficult to fully capture the dynamic changes in the treatment process and has certain limitations. To address this problem, some landfills use a double-layer anti-seepage system in their design to reduce the risk of leachate pollution to the surrounding environment. At the same time, monitoring wells and gas sampling ports are set up to collect groundwater and gas data for laboratory analysis, which reduces the direct hazards of medical waste to a certain extent.
[0004] However, this type of monitoring scheme relies more on passive monitoring and post-intervention, and it is difficult to provide timely warnings of sudden problems such as leachate leakage or excessive gas concentration. Therefore, the technology and means of medical waste treatment monitoring still need to be further optimized to achieve more efficient dynamic monitoring and risk prevention and control.
