摘　　要：1000 MW燃煤机组火电厂排放污染气体中二氧化硫(SO_(2))浓度是我国火电厂排放污染的重点控制目标,为了研究SO_(2)浓度扩散对周围环境及人们身体健康造成的影响,对SO_(2)浓度扩散进行了模拟研究。首先,根据电厂的实际排放数据建立了高斯羽流扩散模型,利用该模型模拟在大气稳定度相同的情况下模拟不同的风速对SO_(2)浓度扩散分布规律的影响,并且分析SO_(2)浓度扩散的距离及范围。结果表明,SO_(2)浓度扩散与风速及大气稳定度有着密切的关系,风速越大,越有利于SO_(2)浓度扩散及气体的稀释,并证明了利用高斯烟羽模型模拟有害气体扩散具有较好的实际参考意义。The concentration of sulfur dioxide(SO_(2))in the pollutants discharged from 1000MW coal-fired power plants is the key control target of thermal power plants in China.In order to study the influence of SO_(2)concentration diffusion on the surrounding environment and human health,the concentration diffusion of SO_(2)is simulated.The concentration diffusion of SO_(2)is simulated.Firstly,a Gaussian plume diffusion model is established by emission data of power plant.The model is used to simulate the distribution of SO_(2)concentration for different wind speed on under the same atmospheric stability.The distance and range of SO_(2)concentration diffusion are analyzed.The results show that SO_(2)concentration diffusion is closely related to wind speed and atmospheric stability.The higher the wind speed,the more favorable the SO_(2)concentration diffusion and the dilution of gas.It is proved that the proposed model has good practical reference significance,and provides an effective method for monitoring air pollution.
