摘要
选用"制定地方大气污染物排放标准的技术方法"中大气污染物地面浓度高斯公式作为基本公式,并采用点到直线的距离公式计算垂直于平均风向的水平横向距离y和下风向距离X,编制多点源排放在城区网格交叉点上的落地浓度叠加值的计算模型和软件,以丹东市采暖锅炉排放SO2为例计算多点源网格落地浓度。
Gauss Formula that was used for calculating pollutant ground concentration in Technological Methods for a Region to formulate its Atmospheric Pollutant Emission Standard was adopted as the basic formula. Besides, the horizontal distance ＂y＂ and downwind distance ＂X＂ perpendicular to the average wind directions was eMeulated with the beeline and dot distance formula. Accordingly, the calculation model and software for the calculation of su- perposition value of ground concentration at grid intersections among districts with multi - point source pollutant emission was developed. By taking the SO2 emission from heating boilers in Dandong City as an example, the model is verified.
