  • 摘要: 在污水处理厂的主要处理工艺段设置采样点,采用在线监测仪,检测空气中恶臭及挥发性有机物(VOCs)的浓度,明确主要恶臭物质和排放源,研究恶臭及VOC在不同季节的逸散特征。结果表明,恶臭和VOC的排放主要集中在进水区,浓度与进水水质相关。粗格栅间是主要的恶臭源,其恶臭、TVOC、硫化物和胺类的浓度分别为3 458.54~5 028.03 OU、120~221 mg/m3、253~464 mg/m3和15~36 mg/m3,占各个监测点浓度总量的80.6%、93%、90%和89%。主要的恶臭物质为硫化氢和氨,其浓度对应的臭气强度超过4级。恶臭与VOC的排放呈现季节变化,夏季的浓度明显高于冬季。相关性分析显示,恶臭浓度与TVOC、硫化物、胺类浓度具有明显的相关性。
    Abstract: Sampling sites were established in the main processing units of a wastewater treatment plant. The concentrations of odors and volatile organic compounds (VOCs) were detected by online monitoring and their seasonal emission variations were investigated. The main odorous substances and emission sources were identified. Results showed that odors and VOCs were mainly emitted in the water inlet areas, and their levels related to water quality. The coarse screen was the dominant emission source of the wastewater treatment plant used in this study, 3 458.54 to 5 028.03 OU of odor, 120 to 221 mg/m3 of TVOC, 253 to 464 mg/m3 of sulfur compounds, and 15 to 36 mg/m3 of amines were detected from the screen. The proportions of total emissions from all monitoring sites were 80.6%, 93%, 90%, and 89%, respectively. Hydrogen sulfide and ammonia were the dominant odors and their corresponding odor intensity reached level 4. The emissions of odors and VOCs presented seasonal variations. Levels emitted in summer were much higher than those in winter. TVOC, sulfur compounds, and amines exhibited correlation with odor concentration.
