摘要
基于长三角典型城市大气VOCs排放清单识别的8个VOCs主要排放行业,选择11家代表性企业,实测研究了VOCs治理装置、排放现状、排放组成特征,并计算相关行业排放的臭氧生成潜势.结果表明,不同净化技术对非甲烷总烃(NMHC)的去除效率差异大,存在净化后浓度增加的现象,目前的环保装置对废气的处理有待优化.本次采样的大部分企业存在NMHC、苯、甲苯、二甲苯超标现象,其中甲苯的超标情况最严重.对于筛选的8个主要行业,芳香烃和含氧VOCs,是最主要的排放化合物,芳香烃是对臭氧生成贡献最大的化合物.在不同行业中,VOCs组成存在显著差异,因此在制定VOCs减排控制措施时,应优先减排对臭氧生成贡献大的行业.
The status of treatment equipment,the emission characteristics,and the ozone formation potential（ OFP） of volatile organic compounds（ VOCs） for 11 typical enterprises,which were categorized into the 8 major VOC emission industries identified by the emission inventory of a typical city in the Yangtze River Delta,are discussed in this paper. There was a large difference in the removal efficiency of non-methane hydrocarbon（ NMHC） between different treatment techniques,and even an increase in concentration occurred after some of the treatments. The current treatment equipment for VOCs needs further optimization. The emissions of NMHC,benzene,toluene,and xylene in most of the surveyed enterprises exceeded their corresponding standards,with toluene the worst offender. The most abundant compounds in the eight emission industries were aromatic hydrocarbons and oxygenated VOCs,whereas aromatic hydrocarbons contributed the most to ozone formation potential. There were large differences in emission characteristics of VOCs from different industries. Priority should be placed on the industries that have large OFP when control strategies of VOCs are considered.
