T/LNSES 008-2024 Industrial Park Atmospheric Environment Risk Monitoring and Early Warning System Construction Technical Guideline

Scope

Main technical content: **6.7.1 Traceability and Dispersion Simulation Subsystem** The system should have the functions of analyzing pollution sources and tracing pollution sources. By conducting correlation analysis of monitoring data, analyzing the risks of abnormal data corresponding to risk units, and diagnosing pollution sources, combined with GIS maps and atmospheric dispersion models, it can achieve the location, classification, and real-time dynamic simulation of sudden environmental events. **6.7.2** The system should be able to select a preset dispersion prediction model based on information such as the types and concentration changes of atmospheric pollutants detected by monitoring, and import real-time source data and meteorological data into the model to output one or more possible gas dispersion prediction results. **6.7.3** The results of traceability and dispersion simulation should be displayed in a multi-dimensional graphical format on the GIS map interface, plotting pollution dispersion lines and contour maps of pollution concentrations, and displaying the different impact ranges of different toxic and harmful gases in different colors. At the same time, it should be able to dynamically update the early warning process based on real-time monitoring data. **6.7.4** It should be able to provide coordinates of concerned points, propose monitoring factors and monitoring frequencies, and guide emergency response teams to conduct mobile on-site monitoring or manual monitoring. The monitoring results will then be used to correct or optimize the early warning results. **6.7.5** The traceability and dispersion simulation should preferentially adopt the model recommended by HJ169. **6.8 Emergency Response Subsystem** **6.8.1 Emergency Event Registration** **6.8.1.1** The system should be able to classify the causes of the event and register emergency events according to the event type, and intuitively display the location of the accid
