지하역사 미세먼지 제거방법에 대한 적정성 평가

초록

Most of the PM10 in the subway stations is spread by the train-induced wind from the tunnels. Therefore, in order to improve air quality in subway stations, it is important to remove the PM10 in the tunnels. This paper identified the sources of the PM10 and the behaviors of the PM10 in subway stations by analyzing its components and its changing patterns. Air cleaning programs, being used by the subway operating authorities, were evaluated by analyzing the forces, such as gravity, magnetic force, electric force, and air-resistance, acting on the PM10 particles. In addition, it proposed more effective and efficient methods for carrying out the air cleaning programs.
