摘    要:恶臭污染具有主观性和复杂性特点,结合使用仪器分析和嗅觉方法,可以从成分和感官两方面充分反映恶臭污染特征.本文参考USEPA TO14A和GB/T 14675-93方法,选择天津滨海新区内的6个不同类型的工业恶臭源,包括制药、喷漆、炼油、石化、树脂合成和橡胶,采集了各类源工艺流程中通过有组织方式排放的恶臭废气,测定了废气的感官臭气浓度并定量分析了其中的恶臭VOCs物质.使用臭气浓度、恶臭指数及统计学方法进行研究,结果发现,炼油源和制胶源的废气具有非常严重的感官刺激性.甲硫醇等硫化物是炼油源和制胶源的主要特征恶臭物质;苯乙烯和甲苯分别是合成树脂源和喷涂源的特征恶臭组分;对苯二甲酸(PTA)源和制药源属于混合型恶臭源.甲苯是喷漆源和制药源的标识组分;二硫化碳是制胶源的标识组分;间,对-二甲苯可以用来标识石化PTA污染源;炼油源的标识组分为三氯乙烯、氯乙烷和1,2-二溴乙烷;苯乙烯是合成树脂源的标识组分.

关 键 词:恶臭  工业源  特征  嗅觉  标识

Abstract:It is difficult to describe the features of odor pollution, due to its complexity and human’s subjective feeling. The research based on instrumental analysis combined with olfactory measurement, can provide comprehensive characterization of odor pollution. According to USEPA TO14A and GB/T 14675-93 method, samples were collected from six industrial odor sources including pharmacy, painting, oil refinery, petrochemical, resin synthesis and rubber manufacturing, and then were analyzed for odorous VOCs and odor concentration. The odor characterization of these six sources was studied using olfactory odor concentration, odor index and PCA methods. According to the results, oil refinery and rubber manufacturing sources had serious olfactory stimulation. Sulfur compounds, take methyl mercaptan for example, were the major odorous compounds of oil refinery source and rubber manufacturing source. Styrene and toluene were the major odorous compounds of resin synthesis source and painting source, respectively. In addition, toluene was the marker of painting source and pharmacy source. The markers of resin synthesis source and petrochemical source were styrene and m,p-xylene respectively. Carbon disulfide could be used to mark rubber manufacturing source. Trichloroethylene, chloroethane and 1,2-dibromoethane were the markers of oil refinery source.
Keywords:odor  industrial sources  characterization  olfactory  marker
