以包钢工业园区采暖期颗粒物排放清单为基础,利用CALPUFF大气扩散模型进行集群污染源允许排放量动态调控,其模拟调控结果可为污染物排放控制对策、措施的制定提供一定的理论指导,有助于实现包钢工业园区大气环境稳定达标.模拟结果表明,集群污染源单位排污量对控制点浓度贡献随着污染源高度的增加而降低,低矮点源和面源应作为控制重点.在采暖期气象条件不利于污染物扩散的条件下,集群污染源最大允许排放量减少到现有排放量的8.82%,而在气象条件有利于污染物扩散的条件下,其最大允许排放量减少到现有排放量的12.03%,可以实现控制区大气环境质量达标.

Based on the particulate emission inventory during the heating period in Baotou Steel Industrial Park, the model of CALPUFF atmospheric dispersion is used to conduct the dynamic regulation on allowable emission amount, the simulation and control results are able to provide some theoretical guidance for the control strategies and measures for the cluster pollutants emission, and are of benefit to realize stable standard of the atmospheric environment. The simulation results indicate that the concentration contribution rate to the control points by cluster pollutant source unit emission amount reduces with the altitude of pollutant source increases, low and short emission sources as well as area emission sources should become the key control points. During the heating period, the meteorological conditions that do not conduce to the spread of the pollution, the maximum allowable emission amount of cluster pollution source reduce to 8.82% of existing emissions; meanwhile the meteorological conditions conduce to the pollution dispersion, the maximum allowable emission amount decreases to 12.03% of that. Therefore the nation air ambient quality standards of the control area are able to meet.
