【摘要】：VOCs是挥发性有机化合物(Volatile Organic Compounds,VOCs)的英文缩写,是公认的PM2.5前驱体,对人类健康具有严重危害,同时对空气能见度和环境都具有明显影响。近年来,我国工业化进程取得巨大成就,成为亚洲甚至全球最大的工业产品产销国,工业行业连续数十年保持高速发展,企业数量不断增加、规模持续扩大,各行业产能、产量几乎都位居世界前列,为推动我国经济发展做出极大贡献。然而,VOCs排放量因此大幅度上升,尤其是在京津冀、长江三角洲、珠江三角洲等工业活动集中地区。本文以西安市最大的主城区——莲湖区为调查范围。首先,从区域内排放VOCs的工业企业中进行筛选,选取包括化工品生产在内的五个行业的五家具有典型性、代表性的大型企业进行分析。而后,分别进行企业生产状况、VOCs工程治理和排放等方面的详细调查和分类。其次,列举出八类目前国内、国外典型的有机废气治理新技术、新方法进行详细介绍。分别介绍不同治理技术其适用性和优缺点。最后,以上述两个部分内容为基础,以西安这座北方工业化城市为代表,对四大类工业企业有机废气治理措施提出污染控制建议,为目前先进的有机废气治理技术如何运用于各具体工业行业,使其实现技术经济可能性最优提供了参考依据。
[Abstract]:VOCs is an acronym for volatile organic compounds (VOC) and is recognized as the precursor of PM2.5. In recent years, China has made great achievements in the process of industrialization, and has become the largest producer and marketer of industrial products in Asia and even the world. Industrial industry has maintained rapid development for decades, the number of enterprises continues to increase, the scale continues to expand, the production capacity and output of various industries are among the most important in the world, which has made great contribution to promoting the economic development of our country. As a result, the amount of VOCs emission increased greatly, especially in the areas of concentrated industrial activity, such as Beijing-Tianjin-Hebei, Yangtze River Delta, Pearl River Delta and so on. This paper takes Lianhu District, the largest main urban area of Xi'an, as the scope of investigation. First of all. From the regional emission of VOCs from the industrial enterprises to select five industries including chemical products production five typical representative large enterprises to analyze. The production status of enterprises and VOCs engineering treatment and emission aspects of the detailed investigation and classification. Secondly, listed eight types of domestic and foreign typical new organic waste gas treatment technology. The new method is introduced in detail. The applicability and advantages and disadvantages of different governance technologies are introduced respectively. Finally, based on the above two parts, Xi'an is the representative of the northern industrialized city. Four kinds of industrial enterprises organic waste gas control measures proposed pollution control for the current advanced organic waste gas treatment technology for the application of specific industrial industries. It provides a reference basis for the realization of the optimum technical and economic possibility.
