摘要
《"十三五"挥发性有机物污染防治工作方案》(环大气[2017]121号)明确将湖北省武汉市及其周边地区列为VOCs污染治理重点地区。确定湖北省需要优先控制人为源VOCs的行业和重点污染物是实现VOCs类物质因地制宜、突出重点,分业施策治理方略的基础。采用排放因子法,以2015年为基准年,将排放量少于0.01 kt的类别剔除后得到湖北省优先控制人为源VOCs排放清单,并以生物质燃烧源为例,计算其臭氧生成潜势(OFP)。结果表明:湖北省2015年优先控制人为源VOCs排放量约为835.45 kt,燃烧源、工业源和移动源排放量分别为261.52、532.15、41.77 kt。塑料制品制造、石油化工和汽车喷涂是湖北省人为源VOCs排放量前三的工业行业;移动源的排放量占比相对较小;生物质燃烧VOCs的排放占湖北省排放总量的29%,生物质燃烧中排放的臭氧前驱VOCs共72.25 kt,所产生的OFP总量为183.63 kt,需重点控制的污染物为苯、甲苯、苯乙烯、邻二甲苯、1-丁烯、间/对二甲苯、反-2-丁烯。
Wuhan and its surrounding areas in Hubei Province are listed as one of the key regions for the pollution control of VOCs in Working Programme on the Prevention and Control of Volatile Organic Compounds in Period of the 13th Fiveyear Plan prepared by the Ministry of Environmental Protection. The key industrial sectors and primary pollutants of anthropogenic VOCs in Hubei Province are identified as the basic conditions for effective control of VOCs. The emission amount of anthropogenic VOCs in 2015 was calculated based on emission inventory method. Emission inventories of priority control an- thropogenie VOCs were listed after removing the category of emissions less than 0.01 kt. Furthermore, the ozone formation potentials of VOCs emission by biomass burning were studied. The results showed that the emission of the priority control an- thropogenic VOCs in the Province was about 835.45 kt in 2015, among which the emissions from combustion sources, indus- trial sources and vehicle sources were 261.52 kt, 532.15 kt and 41.77 kt respectively. Plastic products manufacturing, petro- chemicals and automobile spraying were the top three industrial sectors for VOCs emission. Emission from biomass burning was account for 29 percent of the total. The emission amount of ozone precursor VOCs was 72.25 kt, and the total amount of ozone formation potential in 2015 was 183.63 kt. Benzene, methylbenzene, styrene, oxylene, 1-butene, m/p-xylene and trans-2-butene are need to be concerned priority of anthropogenic VOCs control in the Province.
