Embodiment

[0075] The invention proposes an industrial park-based atmospheric environment traceability method and system.

[0076] The present invention proposes the refined management technology of "measurement, traceability, pre-governance and evaluation" of air pollution in industrial parks, and uses two Models (air pollution traceability model and pollution diffusion model) and a form ("measurement, traceability, pre-governance and evaluation" task flow form) realize the management of the park's atmospheric environment from early warning to timely response to precise traceability and finally to scientific governance. Closed-loop management of the whole process.

[0077] In the first aspect, the present invention proposes a method for traceability assessment of atmospheric environment based on industrial parks, such as figure 1 , image 3 shown, including the following steps:

[0078] Step S1: When the data to be monitored exceeds the set threshold, it is considered that an abnorma...

specific example

[0141] When the navigating vehicle detects an abnormally exceeded point (such as a leakage accident), the source strength calculation is performed according to the following steps:

[0142] 1. Input the P container pressure, unit: Pa;

[0143] 2. Select rip shape C d , circle, triangle, rectangle (circle=1.00 during calculation, triangle=0.95, rectangle=0.90);

[0144] 3. Estimate the area of ​​the crack A, unit: m 2 ;

[0145] 4. Enter the name of the substance, and the system will automatically match the molar mass M of the substance according to the inventory, unit: kg / mol (this information needs to be combined with the on-site monitoring results);

[0146] 5. According to the embedded algorithm, the gas leakage rate QG, unit: kg / s, the formula is as follows:

[0147] QG=C d *A*P*M*Correction factor.

[0148] At the same time, on-site personnel can also calculate the source strength through actual monitoring, as follows:

[0149] 1. On-site personnel obtain the monit...

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 ...
