济南市大气燃煤污染诊断

根据对济南市大气环境质量的分析,通过多源数值模式的模拟试验,导出不同污染源类型对污染物浓度的贡献率,作出大气SO₂污染来源分析,得出如下结果:济南市SO₂浓度空间分布表现为2个高中心的特点,主要由中架源与低矮源共同作用造成的;低矮源与中架源SO₂排放量之和约占排放总量的1/3,对SO₂浓度贡献之和占主要地位;高架源污染物排放量大,但对整个研究区域的质量浓度贡献较小,如果考虑城市污染对周边的影响,高大的污染源应引以重视;防治和规划济南市SO₂污染最主要的是对中架源和低矮源加以控制. 

Diagnosis of Air Pollution from Coal Burning in Jinan

Based on the analysis of air quality in Jinan,multi\|source numerical model is used to calculate contribution rates of different kinds of sources to air pollution concentration and analyze the sources of SO\-2 pollution.The results are as follows.The spatial distribution of SO\-2 in Jinan displays the characteristic of two peaks,mainly caused by medium\|height and low sources.The sum of medium\|height and low sources occupies one third of the total emission,but plays a primary role in the distribution of SO\-2 concentration.High source has large amount of emission,but contributes less to the distribution of SO\-2 in the region of the study.The effect of high sources on surrounding areas of the city should be considered.Therefore,it is essential to control medium\|height and low sources for SO\-2 pollution control in Jinan.
