Research On Characteristics And Control Of Air Pollution In Chuzhou City

Now the social economy is in the stage of rapid development,but at the same time,the urban ecological environment is also affected by the economic development,the urban ecological environment is increasingly prominent,gradually become the problem of the whole society.Chuzhou is also facing such problems.This paper will collect data of more than 300 micro-stations and national control points of Chuzhou through the atmospheric grid platform monitoring system,and analyze the monitoring data,so as to comprehensively and objectively evaluate the regional air quality of Chuzhou.By analyzing the variation characteristics of air pollutants,we can know the law of air quality changing with time and the characteristics of air pollutants changing with time.Combining with the geographical location of Chuzhou and from the factors such as hydrologic environment,topography and landform,energy structure,climatic conditions and main sources of environmental air pollutants,the author comprehensively analyzed the relationship between the concentration of atmospheric pollutants in Chuzhou and the influencing factors,and proposed effective control Suggestions for the atmospheric environment of Chuzhou.The main contents and results of the research are as follows:(1)AQI(Ambient air quality index)was used to analyze the characteristics of particulate matter and gaseous pollutants in the atmosphere of the study area.According to the analysis results,the pollution situation was graded,and the types and quantities of the main pollutants of each level were recorded.The results showed that the primary causes of pollution were particulate matter and ozone in the pollutants.(2)combined with the natural environmental conditions and social environment,the distribution characteristics and variation trend of atmospheric pollutants are analyzed.The results showed that all the air pollutants had obvious seasonal variation characteristics,except ozone,which showed heavy pollution in autumn and winter and light pollution in summer,while ozone concentration changed from low to high in winter,spring and autumn and summer.From this,it can be further concluded that temperature changes have a great influence on ozone.(3)source parse the city with the reed {langya} of chuzhou district government and chuzhou library for the monitoring of monitoring points,the results show that monitoring period was mainly affected by partial southeast wind,humidity static stability atmospheric diffusion capacity under the condition of bad weather,atmospheric pollutants accumulate together easily,and under the condition of high humidity is more advantageous to the secondary aerosols generated,thus cause air quality is generally mild to moderate pollution.(4)according to the simulation analysis results of backward trajectory on the pollution process of heavy pollution days in Chuzhou city,it can be seen that heavy pollution days in Chuzhou city are mainly affected by pollution transmission in northern cities.Location and meteorological conditions played a role,but local sources also contributed to the heavy pollution.(5)based on the analysis results of atmospheric environment quality in the research area and the relevant policies and programs implemented in the research area,corresponding program adjustment and new preventive measures can be made,so as to improve and improve the atmospheric environment quality in the research area to a certain extent.
