Boundary VOCs forewarning and traceability in chemical industry park based on sensor monitoring
In order to explore the monitoring performance of VOCs sensor and its application in chemical industrial park grid monitoring system,a study on monitoring and forewarning and pollution traceability system at the factory boundary was conducted in Rudong Park,Jiangsu Province,from September to October 2022.The results showed that:(1)The VOCs concentration in the park in October was 7.6％lower than that in September,with the VOCs concentration at the Wolan South site consistently ranking first,increasing by 11.3％month on month;the daily hourly variation trend showed that the higher VOCs concentration was mainly concentrated in early September and late October.(2)The frequency of high,medium and low level warnings in September and October showed an order of magnitude relationship,but the total number of warnings in October decreased by 19.6％compared with September as a whole,and all three levels of warnings had different degrees of decline;the high concentration of VOCs boundary stations were Wolan South,Jingwei South,Hongfudali South,etc,mainly distributed in the southwest area of the park.(3)Using ArcGIS to simulate the spatial distribution of pollution,the high pollution area of the park in September was mainly concentrated in the southeast of the western half of the park;in October,the distribution of area with high pollution levels in the park was relatively scattered,mainly reflected in the southeast and central parts of the western half,as well as a few points in the eastern half;the high pollution area was highlighted to provide strong support for the traceability analysis of the park.
