臭氧层消耗物质控排对大气环境的影响监测研究

Impact of Controlled Emission of Ozone Depleting Substances on Atmospheric Environment

为实现保护臭氧层与大气环境的双赢,对臭氧层消耗物质控排举措及其对大气环境的影响进行详细研究。使用流体力学算法构建水平均匀的大气边界层风场,获得氟氯烃污染物扩散模式,利用核函数法计算氟氯烃污染浓度,同时针对不同污染浓度提出具体的臭氧层消耗物质控排实施方案。研究结果表明,臭氧层消耗物质在大气内的日变化幅度较小,具备夏秋高、冬春低的污染特征,污染浓度呈现逐步降低趋势,臭氧层消耗物质控排方案可有效降低大气环境污染水平。

In order to achieve a win-win situation between the protection of the ozone layer and the atmospheric environment,the control measures of ozone layer depleting substances and their impact on the atmospheric environment are studied in detail.Using fluid dynamics algorithm to build a horizontal and uniform wind field in the atmospheric boundary layer,the diffusion model of HCFCs was obtained,and the pollution concentration of HCFCs was calculated by kernel function method.At the same time,the specific implementation scheme of controlling and discharging ozone depleting substances was proposed for different pollution concentrations.The results show that the daily variation range of ozone layer depleting substances in the atmosphere is small,with the pollution characteristics of high in summer and autumn and low in winter and spring,and the pollution concentration is gradually decreasing.The control and emission scheme of ozone layer depleting substances can effectively reduce the level of atmospheric environmental pollution.
