Description:
This paper studies the characteristics of atmospheric pollutant (SO 2 , NO 2 , PM 2.5 and PM 10 ) and the effects of rainfall on the removal of atmospheric pollutants. The results show atmospheric pollutants concentration vary in different seasons and functional area: atmospheric pollutants concentration in summer and autumn is lower than that in winter and spring; the concentration of SO 2 and NO 2 in coal-chemical industry areas and light industrial areas is higher, the concentration difference of PM 2.5 and PM 10 in different functional areas is very small, the removal efficiency of rainfall on atmospheric pollutant is gradually improved with the increasing of daily rainfall, rainfall intensity and rainfall duration, the ability of rainfall to remove pollutants tends to be stable after daily rainfall and rainfall intensity exceeds 30mm and 20mm/h respectively, the effect of rainfall on the removal of...
