典型非石化城市大气中挥性有机物VOCS污染特征研究VIP免费

摘 要 VOCs(Volatile Organic compounds) 是一种以气态形式存在大气污染物，对人体健康和环境都具有严重的影响。随着中国经济和发展形势的复杂变化，随之而来的是环境问题也越来越复杂，近年来，VOCs 排放量越来越大，而 VOCs化学成分又相对比较复杂，治理过程相对繁琐，由此引起了人们的高度重视。目前，大气挥发性有机物污染防治成为环境治理的重要任务之一。研究挥发性有机物的组成成分及特征可以为研究 VOCs 来源、污染特征及管控策略提供重要的参考依据。本论文以某典型的非石化城市为研究区域,基于 2019 年冬季监测的 72 种VOCs 物种，研究了非石化城市的挥发性有机物的污染特征，结合监测的 VOCs数据，列出 VOCs 排放特征和成分谱特征并对其化学反应活性进行分析；据此得出了典型非石化城市大气挥发性有机物的污染防治对策。关键词：挥发性有机物，VOCs 物种组成，浓度特征、活性分析。AbstractVOCs (volatile organic compounds) is a kind of air pollutants in the form of gas, which has a serious impact on human health and the environment. With the complex changes of China's economy and development situation, the environmental problems are becoming more and more complex. In recent years, the VOCs emissions are increasing, and the chemical composition of VOCs is relatively complex, and the governance process is relatively complicated, which has attracted people's attention. At present, the prevention and control of VOC pollution has become one of the important tasks of environmental governance. The study on the composition and characteristics of VOCs can provide important reference for the study of VOCs sources, pollution characteristics and control strategies.This paper takes a typical non petrochemical city as the research area, Based on 72 VOCs species monitored from2019 in winter, the pollution characteristics of VOCs in non Petrochemical cities and the source analysis of VOCs in the atmosphere are studied. In this paper, the receptor model met...
