交通干道空气中挥发性有机物污染防控技术研究

Prevention and Control Technology of Volatile OrganicCompounds Pollution in Air onTraffic Trunk Roads

车辆行驶在交通干道上会排放大量的尾气,尾气中包含挥发性有机物,很容易造成挥发性有机物污染,给城市居民健康带来严重的损害。为有效净化挥发性有机物,研究一种交通干道空气中挥发性有机物污染防控技术,在该研究中前一部分确定交通干道空气中挥发性有机物浓度,评估交通干道重要程度,并结合交通干道基本参数,计算干道上防控点点距,完成设计防控点规划。将吸附技术+低温等离子体技术组合在一起,设计一种交通干道空气中挥发性有机物污染防控装置,并将该装置放置在防控点处,实现交通干道空气中挥发性有机物污染净化防控。结果表明:经过研究技术防控之后,交通干道空气中挥发性有机物浓度较防控之前有了很大程度的降低,证明研究防控技术的应用效果。

Vehicles driving on traffic arteries will emit a large amount of exhaust gas,which contains volatile organic compounds that can easily cause volatile organic compound pollution and serious damage to the health of urban residents.This paperstudied VOC pollution prevention and control technology in the air of trunk roads to effectively purify volatile organic compounds emitted by vehicles.The paper first determined the concentration of VOCs in the air of trunk roads,evaluating the importance of trunk roads,and calculating the distances between prevention and control points based on basic parameters of the roads in order to plan the placement of these points.By combining adsorption technology and low-temperature plasma technology,a VOC pollution prevention and control device was designed and placed at the predetermined prevention and control points to purify the air from VOC pollution.The results demonstrated a significant reduction in the concentration of volatile organic compounds after implementing the studied prevention and control technology,validating its effectiveness.
