摘要
近年来,居民源排放的餐饮油烟对大气环境影响逐渐凸显。以新密市武装部站点为研究对象,分析了站点处空气质量变化趋势、污染特征及其主要影响来源,在该监测站点周围安置餐厨油烟净化装置并设置不同气象条件下的污染物控制情景,采用计算流体动力学方法对不同控制情景下的空气质量进行模拟,评估了不同气象条件下净化装置对该站点处空气质量的改善效果。结果显示:2019年新密市空气质量相比2018年总体上有所改善,但2019年大气颗粒物浓度仍明显高于现行空气质量标准,颗粒物污染形势较为严峻。在加装净化装置后,不同气象条件下净化装置对污染物的减排均有正面效果,尤其是在不利扩散的静稳天气下,污染物净化装置能有效减轻污染状况,在持续运行的前提下可实现年均颗粒物浓度3~5μg的降低。
The impact of restaurant fumes emitted from residential combustion on atmosphere has become more and more serious in recent years.In this study,the monitoring site of the Armed Forces Department of Xinmi and its surrounding area was used as the research object.Purification devices were placed around the site,and control scenarios based on different meteorological conditions were set up under different control scenarios.This study used computational fluid dynamics methods to to simulate the air quality under different meteorological conditions and evaluated the effect of purification devices on air quality improvement at the site under different meteorological conditions.The results show that the air quality in site of the Armed Forces Department of Xinmi in 2019 has generally improved compared to 2018,but the concentration of particulate matter in 2019 is still significantly higher than the current air quality standards,which means the situation of particulate matter pollution is more severe.With the addition of purification devices,the purification devices have positive effects on pollutant emission reduction under different meteorological conditions,especially under the static weather with unfavorable diffusion.That means the pollutant purification devices can effectively reduce the pollution situation and achieve a reduction of 3-5μg of annual average particulate matter concentration under continuous operation.
