上海市工业区对邻近居民区的大气环境影响分析

Analysis of the Impact of Industrial Zones on the Atmospheric Environment of Neighboring Residential Areas in Shanghai City

上海市某工业区靠近居民区,可能影响区域大气环境。本文以该工业区为例,采用AERMOD模型定量模拟区域污染源现状,明确整改后有机废气排放对邻近居民区的大气环境影响。分析发现,采取部分污染源关停、工艺取消、项目搬迁、废气收集处理等整改措施后,各污染因子网格点最大落地浓度均能满足相应环境质量标准,且各污染因子削减率较高。

A certain industrial zone in Shanghai City is close to residential areas,which may affect the regional atmospheric environment.Taking the industrial zone as an example,this paper uses the AERMOD model to quantitatively simulate the current situation of regional pollution sources and clarify the impact of organic waste gas emissions on the atmospheric environment of neighboring residential areas after rectification.Analysis finds that after taking rectification measures such as partial shutdown of pollution sources,process cancellation,project relocation,and waste gas collection and treatment,the maximum ground concentration of each pollution factor grid point can meet the corresponding environmental quality standards,and the reduction rate of each pollution factor is relatively high.
