Evaluating Atmospheric Pollution of Chemical Plant Based on Unmanned Aircraft Vehicle(UAV)

Although atmospheric environment monitoring based UAV is a cutting- edge technology, it has become an important method for environmental protection departments. It is significant for protecting and emergency monitoring of sudden atmospheric pollution incidents. Qilu chemical industrial zone with high- risk region of contaminative chemical gas emission is took as the study area. In this paper, we combined the rotor UAV system(HY- 1) that equipped with high resolution CCD and the pollution gas monitor with in- situ measurements for three pollution gases of NO, CO and SO2. The results of the three pollution gas concentration distributions at the heights of 150 m/200 m, 250 m, 350 m and the ground level showed that the pollution gases in the chemical industrial zone present a horizontal difference and vertical diffusion characteristics. Analyzing the horizontally and vertically abnormal values of pollution gas concentrations from UAV can be efficient in supporting pollution pre- investigation. This research is a practical application of UAV in atmospheric environment monitoring by environmental protection departments, which can provide a technical support for regular supervision of pollution gas emission in chemical industrial zones and related enterprises.
