Based on the source analysis model, the chemical composition characteristics of the particulates in the atmosphere of the new area were analyzed, and the conclusions of the source analysis of the atmospheric particulate matter in the new area were obtained. Scientific green laser pointer suggestions and opinions were provided for the air pollution prevention work in the new area, and new measures and ideas were provided. Through multi-party verification, sampling monitoring and analysis, motor vehicle dust, urban dust and secondary nitrate have a higher share of PM2.5 in the West Coast New Area, and urban dust, soot and building cement dust have a higher share of PM10.
Compared with the urban area of Qingdao, the dust pollution (especially construction cement dust) in the new area is significantly higher than that in the urban area. 3D lidar scanning technology can choose to cancel the light coefficient as a monitoring factor according to the surrounding environmental conditions and main pollutant components at the monitoring point, and use horizontal scanning to cooperate with conventional meteorological parameters such as wind direction, wind speed, low clouds, air pressure, and temperature. Scientific Efficiently perform data analysis on monitored objects. Beijing Yifu Herong Technology Co., Ltd. monitors the surrounding 3D lidar scan results in the teaching building of the Party School of the district committee.
Investigation and verification of air pollution sources in this area revealed 10 air pollution sources. The scan results show that building construction dust, road dust, and loose coal combustion exhaust gas are the main pollution sources affecting PM10 and PM2.5 in the area. Green laser pointer suggests strengthening management of construction projects, implementing coal-to-gas conversion or clean coal heating in surrounding villages. Wait. Subsequently, the New District Environmental Protection Sub-Bureau notified the 2017 ambient air quality status and existing problems in the West Coast New District.
