城市地下道路污染物排放控制标准研究

Study of Pollutant Emission Control Standard for Urban Underground Road

城市地下道路中由机动车排放的污染气体,无论是通过高风塔排放,还是经由道路隧道排放口通风排出,都会对周边环境空气质量造成负面影响。随着国内相关规范的出台和人们对大气环境关注度日益提升,对城市地下道路中的空气污染物进行净化处理已经成了大势所趋。现着重论述道路隧道排放口污染物排放标准提出的意义、制定方法和指标,以及其对地下道路空气净化技术的指导作用等方面内容,以供同行探讨。

The pollution gases emitted from vehicles in urban underground roads, either by the high wind tower to discharge, or by the road tunnel vent to ventilate out, will all have a negative impact on the air quality of surrounding environment. With the introduction of the domestic relevant regulations and the national attention to the atmospheric environment, it has become an inevitable trend to purify the airpollutants in urban underground road. This paper focuses discussion on the significance, the method and the index of the pollutant emission standard for road tunnel discharge outlet and the guiding role of the air purification technology for underground road.
