【摘要】：工艺过程源和溶剂使用源是我国大气挥发性有机物(VOCs)最主要的工业来源,近年来源成分谱的研究逐步受到重视.本文总结梳理了2000年以来国内外有关工艺过程源和溶剂使用源排放VOCs特征的相关研究,对比分析了不同研究结果的差异,结合不同研究的对象和方法,探讨了影响溶剂使用和工艺过程源排放成分谱研究的主要影响因素.结果表明,工艺过程源下分的32个三级子类(参照国家《大气挥发性有机物源排放清单编制技术指南》源分类方法)中,有相关研究报道的包括八类;溶剂使用源下分的10个三级子类中,有相关研究报道的包括四类.总体而言,细化的行业研究种类比较少,不同行业排放VOCs组成差异大,可比性较差.污染源采集测试方法对同一行业源排放成分谱研究结果有较大影响.此外,成分谱中VOCs物质名录的不统一也不利于不同研究结果的比较;含氧VOCs是上述两类污染源排放的重要组分,需要纳入测量范围.未来,有必要建立开放交互式的工艺过程源和溶剂使用源排放VOCs成分谱库平台,鼓励并形成不同研究结果的共享及录入机制;并建立相关研究成果数据入库规范,包括研究的对象、方法、地区、时段以及样本量等详细信息,以便开展不同VOCs源成分谱不确定性评判.
[Abstract]:Process and solvent sources are the main industrial sources of VOCs in China. In recent years, more and more attention has been paid to the study of source composition spectrum. This paper summarized and combed the related research on the characteristics of VOCs emission from process source and solvent source since 2000 at home and abroad. The differences of different research results were compared and analyzed. Combined with different research objects and methods, the main influencing factors of solvent use and process source emission spectrum study were discussed. The results showed that: 1. Of the 32 tertiary subcategories (drawing up the technical guidelines for the preparation of the National Atmospheric volatile Organic compounds Source Emission inventory) under the process source, there are eight categories reported in the relevant studies; Of the 10 tertiary subgroups of solvent use sources, there are four related studies reported. In general, there are fewer types of research on the refined industries, and there are large differences in the composition of VOCs emissions from different industries. The pollution source collection and test method has great influence on the research results of the emission composition spectrum of the same industry. In addition, the disunity of the list of VOCs substances in the composition spectrum is also not conducive to the comparison of different research results; Oxygen VOCs is an important component of the above two kinds of pollution sources, which needs to be included in the measurement scope. In the future, it is necessary to establish an open and interactive VOCs spectrum library platform for both process and solvent source emissions. (B) encouraging and forming mechanisms for sharing and inputting the results of different studies; In order to evaluate the uncertainty of different VOCs source spectra, detailed information such as object, method, region, time period and sample size are established.
