| 摘 要： | 通过对岳阳城区2007 ～ 2013年663个雨量样本556个酸雨pH以及对应之风向频率下的酸雨率进行分类统计、分析,发现后3年酸雨率明显增高.针对此现象寻求原因,除工业布局、主导风向外,通过对2010年运行的巨型燃煤机组产生的SO2 、NO2浓度值进行模式计算,得出机组运行后对SO2 、NO2浓度值贡献是下游最近3年酸雨率增高的重要原因之一.

| Abstract: | The classification statistics and analysis was conducted on 663 rainfall samples,556 pH value of acid rain,and the acid rain frequency under corresponding wind direction in Yueyang City during 2007-2013.It was found that acid rain frequency is obviously increased in last 3 years.To seek reasons for this phenomenon,in addition to the industrial layout,the dominant wind direction,by calculating SO2,NO2 concentration produced from the giant coal-fired units operated in 2010,it can be concluded that the unit operation producing SO2,NO2 is one of the important reasons for acid rain increasing in downstream in recent 3 years. |
