基于A值法的区域大气环境容量研究——以宁国市工业区为例

Study on Regional Atmospheric Environmental Capacity based on a Value Method——Taking Ningguo Industrial Zone as an Example

大气环境容量是一个区域在满足环境空气质量目标前提下,在区域范围内环境空气所能承纳的最大污染物负荷总量。本文通过A值法计算宁国市工业园区大气环境容量,并通过与大气污染物排放现状的比较,得知宁国市区域SO2、NO2的大气环境容量仍有较大富余空间,而PM10近年来排放量均超过其环境容量,通过大气环境容量的计算分析为宁国市制定总量控制目标及大气污染防治工作提供依据。

The regional atmospheric environmental capacity is the maximum amount of pollutant load that can be accepted by the ambient air in a region under the premise of meeting the local environmental air quality objectives. This article through the A value method to calculate the atmospheric environmental capacity of Ningguo City Industrial Park, and comparing with the present situation of air pollutant emissions, atmospheric environmental capacity of SO2 and NO2 in Ningguo area that there is still a large surplus space and PM10 emissions in recent years are more than the capacity of the environment, through the calculation of air environmental capacity analysis for Ningguo city to develop the total control targets and air pollution prevention and control provide the basis for the work.
