集中供热燃煤锅炉房的大气环境影响预测与评价

Prediction and Evaluation of Atmospheric Environmental Impact of Central Heating Coal-fired Boiler

以某集中供热燃煤锅炉房项目为例,本文结合《环境影响评价技术导则大气环境》(HJ 2.2—2018),采用AERMOD模型进行大气环境影响预测与评价,对AERMOD模型在预测中各参数的设置情况进行了介绍。同时,以SO2预测结果为例,计算了其在正常运行条件下锅炉烟气污染物对周围环境的影响程度和范围,并对其影响污染物扩散的因素进行了分析,为环评从业者在大气环境影响预测和AERMOD模型的使用中提供一定可借鉴的案例数据经验。

Taking a central heating coal-fired boiler house project as an example,combined with the“Environmental Impact Assessment Technical Guidelines for Atmospheric Environment”(HJ 2.2—2018),the AERMOD model is used to predict and evaluate the atmospheric environment impact,and the setting of parameters in the prediction of the AERMOD model is introduced in this paper.At the same time,taking the prediction results of SO2 as an example,the influence degree and scope of the boiler flue gas pollutants on the surrounding environment under the normal operation conditions are calculated,and the factors affecting the diffusion of pollutants are analyzed,which provides the case data experience for the environmental assessment practitioners in the prediction of atmospheric environment impact and the use of AERMOD model.
