滇南中心城市酸雨变化特征及控制对策研究
Study on Variation Characteristics ofAcid Rain and the Control Measuresin the Central City in Southern Yunnan
摘要: 为研究滇南中心城市酸雨变化趋势及成因,对2011~2019年云南中心城市酸雨监测数据进行了统计分析。结果表明:近年来滇南中心城市降雨pH年均值在小幅上升,酸雨频率逐渐减小,2010~2019年均为硫酸型酸雨,2020年转变为混合型酸雨。SO
2的浓度主要受工业排放的影响,NOx的浓度主要受移动源和工业源联合排放的影响。本研究建议加强该地区硫氮协同控制,并着力加强氮氧化物深度减排,提升管控水平,进而改善该区域酸雨的状况。
Abstract:
The change trend and causes of acid rain in the central city in southern Yunnan were studied by statistical analysis of the monitoring data from 2011 to 2019. The results show that the annual pH value of rainfall in the district had increased slightly, and the acid rain frequency had decreased gradually. From 2010 to 2019, the central city in southern Yunnan was all sulfuric acid rain, and changed to mixed acid rain in 2020. The concentration of SO2 is mainly affected by industrial emission, and the concentration of NOx is mainly affected by the combined emission of mobile source and industrial source. Therefore, this study proposes to further strengthen the coordinated control of regional sulfur and nitrogen, and focus on strengthening the deep reduction of nitrogen oxides. Moreover, the acid rain conditions in central cities in southern Yunnan will be improved.
