城市典型地下空间的空气污染特征及其净化对策
Characteristics and eliminating strategies of contaminants in urban underground spaces
摘要：
以现场测试数据和对我国城市地下空间空气质量的相关文献分析为基础，总结了地下商场、地铁车站、地下车库3类典型地下空间内部的空气污染状况，并以图表的形式给出了目前我国典型地下空间中的CO2，CO，可吸入颗粒物PM10，细菌，甲醛，氡等特征污染物的浓度分布数据，并分析其成因。根据目前通风、常用空气净化技术现状以及各类地下空间的污染特征，分析指出去除地下商场和地铁车站内部污染物宜采用控制污染源、通风稀释和复合净化有机结合的技术路线，并指出研发方便、高效的复合净化技术是今后解决城市地下空间污染物净化问题的重要方向。
Abstract：
Based on the field test data and literature analyses of indoor air quality in urban underground space of China, summaries the air pollution character in three types of typical urban underground space, i.e. the underground store, underground railway station and underground garage. Provides the concentration distribution charts of the typical air pollutants, including CO2, CO, inhalable particulate PM10, bacteria, formaldehyde and radon, and analyses their sources. In view of the current ventilation and air cleaning technology and pollution characteristics, points out the technical route of pollutants removal should be properly combined pollution source control, dilution ventilation and complex cleaning for underground stores and underground railway stations. Indicates that development of convenient and efficient complex cleaning techniques is an important trend for eliminating pollutants in urban underground spaces.
