准东工业园区大气污染物对区域内敏感地带的影响研究

Impact of Air Pollutants from Zhundong Industrial Park on Sensitive Areas

本文通过整理准东工业园区2014年度规模以上企业大气污染物排放清单,利用大气污染扩散模型,模拟2014年准东区域规模以上企业排放对周边敏感区域的影响。结果表明:2014年度规模以上企业排放的SO_2、NO_2对各个敏感点均存在影响。其中SO_2排放贡献最高的为北三电厂,贡献浓度为12.3μg/m^3,其次是五彩湾镇,贡献浓度为12.0μg/m^3,其余敏感点位贡献浓度均小于10μg/m^3。NO_2排放贡献最高的敏感点位亦为北三电厂,贡献浓度为8.72μg/m^3,其次是五彩湾镇,贡献浓度为8.69μg/m^3,其余敏感点位贡献浓度均小于8μg/m^3。现有企业为卡山保护局、五彩湾调蓄水库、奇台硅化木、五彩湾服务区等点位首要污染因素。

This paper,based on the air pollutant emission inventory of enterprises above designated size in Zhundong Industrial Park in 2014,simulates the impact of emissions from those enterprises in 2014 on surrounding sensitive areas using air pollutant diffusion model. The results indicate that： SO2 and NO2 discharged by enterprises above designated size in 2014 have an impact on all sensitive points. Beisan Power Station contributes the most to SO2 emission,with a concentration of 12. 3 μg/m^3,the second is Wucaiwan Town,with a concentration of 12.0 μg/m^3,and the concentration contributed by all other sensitive points are less than 10 μg/m^3. Beisan Power Station also contributes the most to NO2 emission,with a concentration of 8.72 μg/m^3,the second is Wucaiwan Town,with a concentration of 8. 69 μg/m^3,and the concentration contributed by all other sensitive points are less than 8 μg/m^3. Existing enterprises are primary pollution factors at Kashan Protection Agency,Wucaiwan Reservoir,Qitai Silicified Wood,and Wucaiwan Service Area.
