摘要
根据自动监测仪器在塘沽区8年来所测得的SO2质量浓度资料,结合塘沽区工业污染排放的状况及其变化特征,对该区SO2质量浓度及其变化趋势进行比较分析,结果表明,2000-2007年SO2质量浓度总体均未超过国家二级标准限值,但SO2质量浓度的变化呈现波动增加趋势。SO2的污染状况始终是采暖期重于非采暖期,防止SO2污染仍将是塘沽区未来空气污染控制中十分重要的任务。
Based on the concentration of SO2 from automatic monitor instrument in Tanggu district of the past 7 years, and combined with exhaust emission and variation characteristics of industrial pollution. This paper compared the concentration of SO2 and the changing trends, the results showed that total SO2 concentration of 2001~2007 did not exceed the minimum limits of national secondary standard, but SO2 in the air showed total increasing trend, SO2 pollution in the heating period was always more serious than the non-heating period, and would prevent the SO2 pollution in the future. It would continue to be a very important mission for the Tanggu district air pollution control.
