摘　　要：根据HJ2.2-2018《环境影响评价技术导则—大气环境》中推荐的估算模型AERSCREEN,预测了相同气候条件、相同地形条件下,通过5m、10m、15m、20m高度排气筒排放的同一污染源强的VOCs废气的地面浓度分布情况。通过软件模拟预测数据分析结果表明,适当提高排气筒高度,可减轻VOCs废气对排气筒附近地面敏感目标的影响,以达到环境保护的要求,对实际的大气环境影响评价具有一定的指导和促进作用。Estimated model AERSCREEN recommended in HJ2.2-2018 Technical Guidelines for Environmental Impact Assessment-Atmospheric Environment,Predicted the same climatic conditions, under the same terrain conditions,The ground concentration distribution of the VOCs exhaust gas of the same pollution source discharged through the 5 m, 10 m, 15 m, and 20 m height exhaust cylinders.The results of software simulation prediction data analysis show that,Properly increase the height of the exhaust pipe,It can mitigate the influence of VOCs exhaust gas on ground sensitive targets near the exhaust pipe.To meet the requirements of environmental protection,It has certain guidance and promotion for the actual atmospheric environmental impact assessment.
