Atmospheric environment tracing and evaluating method and system based on industrial park

Abstract

The invention provides an atmospheric environment tracing evaluation method and system based on an industrial park. The system comprises an abnormal event monitoring unit, an abnormal event retrieval unit, an abnormal event tracing unit, a pollution prediction unit, a management and control task distribution unit, a management and control task tracking unit, an event evaluation unit and a task flow form unit. The method comprises seven steps of testing, tracing, pre-managing, treating and evaluating, an atmospheric pollution tracing model, a pollution diffusion model and a task flow form are utilized to realize the whole-process closed-loop management of park atmospheric environment management work from early warning, timely response, accurate tracing and scientific treatment, the delay and blindness of conventional artificial offline judgment are reduced, and the management efficiency is improved. Early warning information receiving, pollution traceability and situation prediction of daily pollution events, proposing of enterprise governance measures afterwards, supervision and management of enterprise governance work and governance effect evaluation after rectification are achieved.

Description

technical field [0001] The invention relates to the field of environmental science, in particular to a method and system for traceability assessment of atmospheric environment based on industrial parks. Background technique [0002] As a gathering place of various industrial enterprises, the industrial park loads a large number of enterprises in a relatively small area, and each enterprise has a large number of exhaust gas emission sources and VOCs (Volatile Organic Compounds, volatile organic compounds) leakage mark points. The accumulation and superposition of source intensity (that is, the emission of pollutants per unit time) leads to the prolongation of the duration of some organic pollutants, which will continue to deteriorate the quality of the surrounding environment under unfavorable meteorological diffusion conditions. In order to reduce the occurrence of air pollution incidents in the industrial park, the environmental management department of the industrial park ...

AI Technical Summary

Problems solved by technology

The above three supervision methods all have different degrees of defects. First of all, the first one can only realize the early warning of data, but according to the early warning event, the next step is not processed, only the information is given, and the rest of the work content cannot be realized. Online processing and archiving

The second type has a closed-loop process for early warning events, but it lacks auxiliary decision-making means. If it is an enterprise point source early warning, you can go to the enterprise to check the problem, but if it is an environmental quality site early warning, you cannot find out the abnormal data even if you go to the site. Reason, there is no way to complete the problem closed loop

Although the third method adds a model algorithm to assist decision-making, the model traceability can only provide a range. To accurately trace the source, it needs to be determined manually in combination with instruments and equipment offline, and the third method does not combine the system simulation results with the offline verification results. In combination, only simulated traceability is the end. As for whether accurate traceability has been achieved in the end, what is the result of traceability, how much impact the pollution source can have, and the whole process of problem rectification has not been tracked, and the real closed-loop management of early warning events has not been realized.
