临安市大气中二氧化硫污染现状及环境容量测算研究

Pollution Status and Environmental Capacity Calculation of Sulfur Dioxide in Atmosphere of Lin'an City

根据2011年-2015年的监测数据分析了临安市大气中二氧化硫污染现状,并利用"A值法"测算大气中二氧化硫的最大环境容量。结果表明,能源消耗中,原煤占60%以上;大气中二氧化硫日均浓度范围为0~73μg/m3,年均排放量呈现下降趋势;1月份和12月份二氧化硫的浓度较高,7月份和8月份浓度较低。全市二氧化硫环境容量为12.21万吨,城区环境容量为2.96万吨。

The pollutionstatus of sulfur dioxide in the atmosphere of Lin＇an city was analyzed based on the monitoring data from 2011 to 2015, and the maximum environmental Capacity of sulfur dioxide was calculated by using the A - Value method. The results show that the raw coal accounted for more than 60% in the energy consumption; the daily average concentration of sulfur dioxide in the atmosphere was ranged from 0 to 73μg/m^3 , and the average annual emissions presented a downward trend; the sulfur dioxide concentration was higher in January and December, and was lower in in July and August. In the city, the environmental capacity of sulfur dioxide was 122,100 tons, and the environmental capacity of sulfur dioxide in urban area was 29,600 tons.
