Study On Methods Of Improving Air Quality In Qingdao

In order to propose methods of improving Qingdao environmental air quality according to the new situation of Qingdao air pollution,the research makes statistics and analysis to Qingdao air contamination letting situation during the past years,current environmental air quality condition and work development of air pollution prevention and cure.It especially analyzes the resources of inhalational granule which is the main contamination impacting Qingdao environmental air quality.The research also make statistics on changing trend of contamination letting and environmental air quality as well as analyze the effect of main methods of air pollution prevention and cure which have been carried out in Qingdao.The analysis shows that the air quality pollution has been controlled primarily and the environmental air quality has been improved obviously through more investment on environmental protection.enhancement of environment management and work on air pollution prevention and cure including controlling use of hi-Sulfur-coal,eliminating coal-boiler,controlling motor vehicles gas pollution and optimizing energy sources configuration.However,together with the fast development of city economy,the gross letting amount of air contamination presents increase trend potentially which brings about tremendous pressure on maintaining good cantonal air quality. PM₁₀ is the main pollution factor influencing Qingdao environmental air quality,the next is SO2. In winter,the pollution load modulus of SO₂ is the most and pollution occurred is more severe comparatively.According to development planning of Qingdao society economy,the main factors affecting Qingdao environmental air quality in the future and main issues of air pollution prevention and cure are investigated.It indicates that the main challenge of air pollution prevention and cure is that letting quantity of SO₂ is large,granule pollution impacts widely and NO-x pollution is in uptrend gradually.The granule sources are flappy dust,coal soot and construction concrete dust mainly and the flappy dust is the largest contributor.
