机动车辆尾气(CO)污染控制研究

Study on Motor Vehicle Exhaust Pollution (Co) Control

CO的危害对人体健康是致命的,然而CO的主要来源是汽车尾气。所以确定CO为排放因子及重点研究对象,最终得到评价模型,为公路建设项目设计、交通控制、环境污染控制、节能减排和环境评价等提供重要依据。与传统已知道路交通量通过气体排放模型、扩散模型得到排放量的方法相比,用大气污染总量控制的思路,通过道路尾气浓度反算出道路交通量。首先,采用testo435多功能检测仪测量上海市典型道路的尾气CO排放量与标准对照,通过评价模型计算CO排放在满足标准下上海市典型道路允许通过交通量的极值。最后,通过案例分析验证模型的合理性、准确性。案例分析结果表明:该评价模型具有良好实用价值。

CO is harmful to our health, even course death ,and the main source of CO is automobile exhaust. So in this article determines that the CO is the emission factor, and finally get evaluation model. Provide an important basis for the highway construction project design, traffic management, environmental pollution control, energy saving, environmental evaluation, and so on. Compared with the traditional method that calculates road traffic volume through air emissions model, emissions diffusion model, this article according to total amount of air pollution control, calculates the road traffic volume by road exhaust density. First of all. This article measures Shanghai typical road exhaust CO emissions by testo435 multifunction detector, and measurement results compared with the national standard control, and according to the standard in automobile exhaust emissions calculates the extreme values of the traffic volume over the road. Finally, through case analyze validates the model of reasonable and accuracy. Case Analyze results show that： the evaluation model has good practical value.
