Study On The Reasons And Controlling Countermeasures Of Ozone Pollution In Shunde

Recently, air pollution has become one of the hot topics that cased much attention. As the rapid urbanization and industrialization of Pearl River Delta region, the combined air pollution is plaguing the major urban area in PRD region. Shunde District, located in the heart of PRD region, is seriously polluted by ozone. In order to change the situation that Shunde invested lots of resources but barely improving the air quality, this study would targe the ozone pollution, considering the current conditions, to rase some control strategies according to the call of environmental policies.This study used the currently major air quality modeling tools for atmospheric research, and creately used RSM model to do the ozone dynamic source contribution analysis based on the WRF-CMAQ simulation system with team self-made emission inventory. Using this method, the study analyzes the ozone space distribution, the ozone precursors sentivite area and the source contirbution.The result shows that, in 2014, Shunde District was still in the heart of ozone pollution area at PRD. The ozone season was from April to November. Summer and autumn had the highest value of the whole year. Shunde District was a VOCs sensitivite region and effected by Guangzhou, Shenzhen and Dongguan cities more than 8%. The local major source of ozone precursors was VOCs industrial source(4.18 ug/m3) and mobile source(2.9 ug/m3). Base on the results of Ozone control scenario, only strengthen VOCs emission reduction and regional control could Shunde District reach the ozone standard. Therefore, the point of control strategies was VOCs reduction and regional control.
